Define Meta attributes at runtime

[Isaac]

Hi folks,

I'm wondering if it's possible to set / redefine Meta attributes of a 
given model at runtime.


The problem arises because I'm using a framework with many classes 
defined there, and interacting in a right way. I need to redefine some 
of Meta attributes of that class, but without overriding framework file, 
because it can cause many trouble in any update.


Anyone know how I can access them?

To set an example:

folder1
__init__.py
models.py

from folder1.models import ModelTrouble

ModelTrouble.Meta.verbose_name = "my_verbose_name"

Thanks in advance
Isaac

Looking for 4b gateway implementation

[Isaac]

Hi folks,

I'm looking for a django app or python package to interact with 4b 
gateway. I know there are others implemented, like sermepa or paypal, 
but can't find anyone with 4b.


Anyone know something about it?

Set order from admin

[Isaac]

Hi folks,

I've having trouble to find a clear solution to my problem. All I want 
is to set a relation between 2 classes, and set filter order from admin 
to the rest of queries.


pseudocode:

Class A
has_many B
Class B
foreign_key A

And then, I want to retrieve B objects from a given A instance in the 
same order as introduced (or changed) in admin.


Any clue about some clear mode to implement it in django?

Thanks in advance

Adding new js to admin

[Isaac]

Hi there folks,

I'm trying to add raw tinyMCE support for my project. I don't want to 
use the django-tinymce app, as it introduces some features that I don't 
want to load in my project.


I followed instructions from
https://code.djangoproject.com/wiki/AddWYSIWYGEditor
and can't get it working. I've tried to insert that js tuple from model 
and from modeladmin, but neither works. I'm using django 1.3, and all I 
need is to introduce the right js scripts in admin templates, but don't 
know how to do it.


Any clue?

Thanks in advance

Showing per-user information in admin

[Isaac]

Hi dudes,

I'm having trouble at finding a solution for my problem. All I want to 
do is tune django admin to show, for a given user an a given model, only 
instance related to that user.


my pseudocode

class User
...
class A
foreign_key User

A1 related to User1
A2 related to User1
A3 related to User2

then, I want that User1 was only be able to see A1 and A2, and User2 was 
only be able to see A3.
I know that I can create filters to allow user to filter instances, but 
all I want is not to allow user to make that decision, it will be only 
able to see what its related.


Any clue about how to use admin in this way?

Thanks in advance

Problem with translations

[Isaac]

Hi folks,

I'm having a problem with a single module and its translations.

This module has some lazy translation (the same as other modules), but 
in admin, it spreads an error.

Error is the following:

TemplateSyntaxError at /admin/tieredpricing/pricingtier/add/
Caught TypeError while rendering: Lazy object returned unexpected type.
Request Method:GET
Request URL:http://localhost:8000/admin/tieredpricing/pricingtier/add/
Django Version:1.3
Exception Type:TemplateSyntaxError
Exception Value:
Caught TypeError while rendering: Lazy object returned unexpected type.
Exception Location:
/usr/local/lib/python2.7/dist-packages/django/utils/functional.py in 
__wrapper__, line 197

Python Executable:/usr/bin/python
Python Version:2.7.1

In template 
/usr/local/lib/python2.7/dist-packages/django/contrib/admin/templates/admin/includes/fieldset.html, 
error at line 6

Caught TypeError while rendering: Lazy object returned unexpected type.
1 
2{% if fieldset.name %}{{ fieldset.name }}{% endif %}
3{% if fieldset.description %}
4 {{ fieldset.description|safe }}
5{% endif %}
6{% for line in fieldset %}

At line 6.

Then I traced that error to its dispatcher, and I found the following:

at line 402 of file django/forms/forms.py there is the following line:
self.help_text = field.help_text or ''

my problem is that field.help_text must contain an unicode string (u'') 
and not that weird object that is containing,



I've found a way to solve it, and is to call __unicode__() function on 
that object, that explicitly gives me the right unicode string, but that 
code is django core, and I don't know if it's a django issue.


Can anybody help me plz?

Thanks in advance

Multiple websites but one authentication system

[Isaac]

Am working on a company website and there will be having more websites as 
time goes on, they don't want to be creating authentication system in each 
of their website. To avoid stress in creating multi account on these 
platform, there is a need to have one website that will do everything 
relating to authentication and authorization, just Google is.
 For example we will have domain1.com which will handle everything relating 
to  authentication and authorization(Signup,Signin,Password reset, Password 
change, Logout) while other domains like domain2.com, domain3.com, 
domain5.com etc will be falling back to domain1.com for authenticating 
users. Plz any suggesting on how i can do this will be highly appreciated.

Re: Multiple websites but one authentication system

[Isaac]

Am trying to understand what you said sir but am still confuse, how will 
the domain2.com recognize that this person is a user ? Also how will the 
database schema  look like ? Will the two database be connected in a way ?

Re: Trouble with stockphoto

[Isaac Alston]

You do have to add to urls.py. I'm using stockphoto on one of my
sites, you can see my site's code here:
http://svn.jayparlar.com/website/trunk/awwca/


Thanks for this. What I meant was the urls.py in the stockphoto
directory (sorry I didn't make it clear). I notice that you've not
changed this (but you have changed the urls.py for the whole site, as
was in the install :-) ). Here's my urls.py for the whole site, I
can't see why it doesn't work:

http://dpaste.com/4716/

The problem does not seem to occur when I go to /stockphoto (I get a
TemplateSyntaxError (saying it can't find 'load markup'), but I think
that's good because it shows it's finding a template ;-) :-)). The
problem occurs when I go into the 'edit' part of an admin page, and
the link to the photo is given as:

http://127.0.0.1:8000/admin/stockphoto/photo/2/photos/2007/01/11/Family-2006-09-10_012.jpg

for example.

Here is my settings.py: http://dpaste.com/4717/ ; of particular note
are STOCKPHOTO_BASE and STOCKPHOTO_URL which may be causing this.

Any advice would be appreciated.

Thanks,

Re: Trouble with stockphoto

[Isaac Alston]

Your paste bin links don't seem to be working for me, but I'm going to
guess that your STOCKPHOTO_BASE and STOCKPHOTO_URL aren't right. The
link to the .jpg itself shouldn't have 'admin' in it anywhere, unless
you have your media setup in a very odd way.

This is strange, I'll paste them somewhere else, sorry about that:
http://pastebin.com/860489

Just in case that's broken as well:
STOCKPHOTO_BASE='/photos/'
STOCKPHOTO_URL='/photos/'

MEDIA_ROOT = '/home/isaac/django/threeci/smedia/'
MEDIA_URL=''

All of my media is in /smedia. I'm using runserver so I don't have a
'media server' setup yet - I've put something into urls.py from the
Django docs, which lets you serve stuff out of a folder without
setting up a 'proper' server while in development.


For my site, for example, one of the .jpgs have the link:
http://media.awwca.ca/site_media/stockphoto/2006/09/17/HPIM1621a.JPG

Is this taken from the admin 'edit' page for your photo?

Thank you very much for your time.

Re: Trouble with stockphoto

[Isaac Alston]

Hmm, that MEDIA_URL worries me. Can you try setting that to something
more concrete?


Ok, I tried setting it to "127.0.0.1:8000" (was the only thing I could
think of) and it didn't do anything, so I decided to do a fresh
install of stockphoto. Upon doing this, I now receive a new error:
"threeci.stockphoto: string index out of range" when I try to syncdb
(or go to the app). Curiouser and curiouser.

The only changes I've made, was set the stockphoto urls to '' (because
I just wanted a default install - I thought perhaps 'photos' was
causing the problem).

I wish it worked.

Re: Trouble with stockphoto

Can you paste the full traceback for the string index error?

That's the problem: there isn't one (that I can see), the error is
given by runserver:

$ python manage.py runserver
Validating models...
threeci.stockphoto: string index out of range
1 error found

Is there elsewhere I can look?

Ok, I figured this part out. I looked at the stockphoto/models.py
code, and discovered it was doing something like STOCKPHOTO_URL[-1],
which was obviously causing the error, but I couldn't work out why.
Then I realised that if STOCKPHOTO_URL was already defined in
settings.py as '' then it would be trying to index an empty string
(which would fail). I removed my entries to STOCKPHOTO_URL and that
error has now disappeared.

Now everything is at a default install, but it's not fixed anything,
the link in admin is still:
http://127.0.0.1:8000/admin/stockphoto/photo/5/stockphoto/2007/01/17/newser.jpg
for example. Highly frustrating.

Re: Trouble with stockphoto

[Isaac Alston]

The problem is most likely with your MEDIA_URL. Make sure it ends with a '/'


Thank you very much. That seems to be it fixed :-D. First I had
MEDIA_URL set to:
' ' then
'127.0.0.1:8000', then
'127.0.0.1:8000/' then
'/', then finally
'/smedia'

which got it working. I'm so happy :-). The only thing I'm concerned
about is a) why didn't it want a URL and b) what's going to happen
when I deploy? How will this change?

Many thanks,

Re: memcached backed

[Isaac Sparrow]

I think Mark is referring to the actual 'replace' functionality of
memcached. From http://www.danga.com/memcached/

replace -- sets in the cache only if the key already exists

As opposed to:

set -- unconditionally sets a given key with a given value

Scaling django (nginx + apache + mod_wsgi + postgresql)

[Isaac XXX]

Hi folks,

I'm developing a new application that should get high traffic. Right 
now, I've other projects with the follow architecture:


Nginx on front: serving static content and redirecting to apache for 
dynamic data

Apache+mod_wsgi: serving dynamic pages
PostgreSQL: backend for data storage (RDBM)
Memcache: for caching purposes :)

All my deployments use a single server, with single frontend/backend (1 
nginx, 1 apache, 1 postgresql). The requirements for this new project 
are really large, and I think I will need to scale all system. Can 
anyone suggest me an all-in-one tutorial, discussing the main points on 
scale a system?


I know there are different alternatives for DB (master-slave, 
clustering...), nginx can serve as a reverse proxy or not... and I need 
to merge all this information in a single scalable system, but I can't 
find an unified source of information.


Can anyone help me on it?

Re: Scaling django (nginx + apache + mod_wsgi + postgresql)

[Isaac XXX]

Hi there,

thank you for response Tom.

Actually, I've a complete idea at how to build this system, but I lack 
the exact information about how to join systems, and what I was looking 
for was a source of cohesive information on all systems. At least, when 
I finish to build that system, I will write this tutorial.


For someone who can help me, I will describe here what I thought it can 
be this structure:


- 1 nginx, as a reverse proxy on frontend, serving static/media and 
redirecting content to apache clusters

- n apache servers, with mod_wsgi, serving dynamic data
- m postgresql servers, in a master-slave flavour

Cheers,

Isaac

There is unlikely to be one authoritative source that will explain
precisely how to scale an app - part of this is it is domain specific
what "scale" and "app" mean!

So first off, "scale". You can scale up, or out. Scaling up means
running everything on faster hardware. Due to how IT progresses, every
18 months you can replace your server with something twice as fast.
Scale out means running everything over more boxes. Scale up is
trivial, just spend more money, scale out can be harder.

Most parts of the stack are easy to scale, because HTTP itself is
stateless and therefore easy to scale. Eg, if you have a nginx
frontend, serving static files and proxying to backend servers for
static content, and the nginx server is overloaded, it is easy to add
a balancer to route HTTP requests to multiple nginx servers.

The same is true for dynamic content - need more workers, add more
machines, and tell nginx to talk to more machines.

The only tricky aspect of scale out is database. Most databases do not
have a simple 'scale out' option. With postgres, you can setup
master-slave trees, but this only expands your read capacity, all
writes have to go through one server (and then all the slaves, making
it more expensive the more slaves you add).

The only true way of scaling out with database servers is to shard
your data, splitting it up by some arbitrary algorithm (usually on
user), but sharding isn't easy, you will have to design your database
and app around it. There are some very good videos, docs and talks
from the likes of Facebook and the like, sharding is not a panacea and
requires a lot of work.

Cheers

Tom

Re: Scaling django (nginx + apache + mod_wsgi + postgresql)

[Isaac XXX]

Hi Tom,

you're right, I was not really explicit about what were my lacks of 
information. Right now, the following points are the ones I can't found 
a howto for the desired deployment:


- Create a master-slave system on postgresql, maintaining all systems up 
to date, distributing reads, and centralizing writes
- How to configure a cluster of reverse proxies (a single reverse proxy 
can not be enought, and I need to plan to deploy more than 1 load balancers)


The rest (configure apache with mod_wsgit, configure nginx to serve 
static content and so on), is now solved on my current deployments, so 
it should not be a problem on a distributed environment.


Cheers,

Isaac

I'm confused about what you are confused about - you seem to grasp
precisely what is required.

IE, which of the following Qs are you stuck at:

How to configure nginx to reverse proxy and balance to other http servers?
How to configure apache, mod_wsgi and django?
How to configure pgsql in a master/multiple slave environment?
How to configure django to issue write requests to the write master,
and distribute reads to read-only slaves?

Hi Isaac,

If there is one thing I have learnt about scaling apps, it's about 
trying things out for yourself.


Sure there are some best practice guidelines (i.e. serving files from 
nginx, or using apache's X-SendFile rather than streaming out via the 
webapp), but if someone comes along and tells you to use X instead of 
Y, then you don't get the advantages of learning "the hard way".


Another important note is that scaling rarely goes up on a 1:1 ratio, 
i.e. the configuration and resources required to handle X number of 
requests/sec, may be completely different if you need to handle Y 
number of requests/sec.


And often what works for one person, won't work for another (scaling 
is entirely dependant on your application, despite what any of these 
cloud providers might tell you!)


In my own experience, I've found that;

* SSDs with Percona MySQL, resolves a LOT of performance problems - 
but don't abuse it

* Lots and lots and lots of query tuning and InnoDB tuning
* New Relic to identify bottlenecks
* IO contention is a big thing
* Snowball prevention (i.e. you set max clients to X, your backend 
can't handle it, your requests stack up, the load balancer forces time 
out, and your database gets smashed - or you set max memory too high, 
server goes into swap etc).

* uWSGI + nginx is amazing
* Identify where your bottlenecks are (in my own experience, IO/memory 
tends to come up more often than CPU)


Sadly I haven't tried PSQL so I can't offer any advice on this - 
Percona are dragging MySQL kicking and screaming into the 21st century 
and really doing some amazing things, but it's by no means perfect!


The above has helped us grow past 8k-12k requests/minute, the largest 
database we manage is around 1.1 billion rows weighing in at 160GB+, 
and we maintain around 60+ servers.


I should reiterate, the above is purely based on my own experience and 
use cases - I am by no means an expert on the subject and I'm still 
learning approaches on a daily basis - so this is really meant as 
"food for thought" rather than a "this is how you should do things".


Hope this helps a bit!

Re: Scaling django (nginx + apache + mod_wsgi + postgresql)

[Isaac XXX]

Hi there,

maybe you're right, but I'm not really worried about RAM footprint, or 
resources consumption. I'm concerned now on architecture, setting a 
right scalable system, and a right cluster of systems, without lacks of 
communications between them.


Underlaying technologies can be easily replaced (say apache-mod_wsgi for 
gunicorn or uwsgi), and some performance improvements can be made, but 
this is not what I'm looking for. I'm looking for the tools to generate 
a robust system, balancing requests through several systems, and 
allowing increase the size of this system (adding more servers) without 
trouble.


Cheers,

Isaac

Why not just ditch Apache entirely and just use Nginx for serving all 
media (both static and dynamic)? You can then save quite a few 
resources as you only need to run one HTTP server rather than two.


Using Nginx to serve Django content works well. Just serve your Django 
application via FastCGI or uWSGI and you'll significantly simplify 
your configuration and reduce RAM usage on your servers as well.

Alternatives to celery

[Isaac XXX]

Hi folks,

I need a solution to create cron-like jobs into my django projects. I've 
a server with several projects.


I've testes celery, and it seems to work well with only 1 project, but 
when I need to set up several projects with celery support, I can't 
figure how to do it (because daemonization of celeryd process, described 
here 
http://celery.readthedocs.org/en/latest/cookbook/daemonizing.html#daemonizing 
only describes how to start workers for a single process because this 
directive CELERYD_CHDIR="/opt/Myproject/").


Well, my question is the following:

Is there any good tutorial about deploying django with celery on several 
projects, sharing celery support? if not, is there any alternative 
viable to celery for django?


I've found APScheduler, that seems to be a good scheduler for python, 
but integration with django seems a bit tricky. Is it a good alternative?


I will be pleased to read all your feedback about it.

Thanks in advance,

Isaac

Video conference on django app

[Isaac XXX]

Hi folks,

I know that it's not mainly django topic, but I know here's is a well 
documented community through several areas.


I need to set a video conference (1 on 1) feature for a project in 
django. Can you provide me some hints about open-source (or 
free-royalty) apps, or frameworks, to get a simple videochat running in 
my nginx-apache-django environment?


I don't care if I need to install aditional server (like red5), but will 
be helpful if you provide some tutorial about how to deploy it along app.


Thanks a lot!

Force exception raising when transaction fails

[Isaac XXX]

Hi everybody,

I run into a weird scenario, caused by a complex code involving threads 
and so on.


The problem arised in some point, with a DatabaseError exception, saying:

/current transaction is aborted, commands ignored until end of 
transaction block/


Obviously, the line which arises that error is the next one after 
transaction is corrupted. So, my question is: how do I can force django 
to raise exceptions when a given transaction fail?


An example is the following

func1()
func2() <-- Here, a db transaction fails, making all next calls raise 
that DatabaseError exception

func3() <-- Here DatabaseError is raised

I just want that func2 notice me that there is an error with its 
transaction.


Thank you in advance

Vyrphan

"Principle of least privilege" in accessing a DB from an app

[Isaac Perez]

Hi guys,

I'm creating a new app and I'd like to know how would be the best way to 
implement the principle of least privilege.
At the moment the DB has 5 users:

   - 1 is the root user for the DB (which I don't want it to be used by the 
   webapp)
   - 1 has read access to the data fields
   - 1 has write access to the data fields
   - 1 has read access to the users table
   - 1  has write access to the users table

What I intend to achieve is that if in any occasion we've got a sql 
injection for whatever the reason, the access to the DB from the app form 
will be as limited as possible.

If using python directly I would create a DB connection for each 
functionality so they use the right DB user and have the right permissions.

In Django, though, as you have to configure the default DB access in the 
settings and it has to sync, etc... I'm not sure what will be the best way 
to implement that splitting of privileges.

I've configured the 5 connections in the settings but not sure how to best 
use them for the different functions of authenticate, read and write from 
the DB.

Any ideas?


Thanks,
Isaac

Re: "Principle of least privilege" in accessing a DB from an app

[Isaac Perez]

Hi Dennis,

yes, we are going to filter the input and the parameterized queries.
But I always prefer to have more than one layer of security.
And users won't be using any sql queries, they will just input text.

Does the django configuration always need to have full access to the DB?

Thanks,
Isaac

Re: "Principle of least privilege" in accessing a DB from an app

[Isaac Perez]

Hi Tom,

my main goal is to avoid that the access to the users table by anything
else other than the authentication module.
I understand that writing the app correctly and filtering the input, etc...
will do the same, but it's just another layer of security.

I'll take a look to the DB routers and how this can be implemented.

Thanks for your reply.

Re: "Principle of least privilege" in accessing a DB from an app

[Isaac Perez]

Hi John,

I think you are going one step further of what I intended to protect from.
That makes me think about what you are saying but I think it's going to be
too complicated, I'll have to see the risk of that happening.

In a few words what I want to protect from is that an sql query could be
passed in the main input text box and it could access other users passwords
or information.
Also don't feel comfortable with the app having root access to all the DB
if it doesn't need it for it's main function, just in case.
It may be unlikely that this happens and we are implementing other input
controls, etc...
But I thought it would have been easy enough to just have different
connections and use each one for a different function inside the app.
If routing does that, I think it's enough.

If the whole app gets compromised, we are in trouble :-)

Thanks for your reply
Isaac

Getting related values from map table with foreign keys

[Isaac Perez]

Hi,

I'm building an app that has some text with tags, the tags are mapped to 
the text through a mapping table (toxi model).
Something like that:
TEXTID <-->TAGID<-->TAGID
TEXT  TEXTID TAG
What would be the best way to display the text and its tags?

I'm very new to django, and programming in any case,  I can create a list 
for the texts for a certain user, but I don't see how to add only the tags 
for that text in the same list or create somehow a hash with both values.

Is there a django way to do this?

Thanks,
Isaac

Problem with layout

[Isaac XxX]

Hi friends,

recently I upgraded my django installed version to 1.3.

To test it, i got a free html/css template from a page, and started a little
web. The surprise came when I open development webserver, with all static
files configured properly, and the resulting website (without any
modification, only serving the same web template from django instead of
filesystem) is wider, and some parts are malformed.

I used the same html template (without modifications), and the same images
and CSS (CSS only modified to get properly routes).

Then, i set the same index.html and served from django server as static file
(without using django routes, only servinc static html file). This file is
malformed too, at the same way as serving as django page. The last test was
to open that html file, from the same browsers, but this time from
filesystem, instead of from django. File display correctly all layout.

Any idea about what is happening?

Thanks in advance

Django admin and changes

[Isaac XxX]

Hi mates,

i'm having trouble using django admin. Currently, i've finished a project,
and it is the only issue i've open.

When i add or update something through django admin interface, the rest of
the web does not notice it. I need to restart server, and then all behaves
in the normal way (new records are displayed).

I'm not using any cache, so cache is not the problem. I will deploy my
project in a production environment soon, and this is an issue that must be
arranged before this last step.

Thanks in advance!

Problem with translations

[Isaac XxX]

Recently, i've found a problem with i18n translations in Django.

All my translations are located inside views functions, templates and some
of them are in a file called forms.py (where i store some of my forms).

The problem arise when I render that forms. First render time, seems that
locale is applied, but next times the same locale is displayed again,
without beign able to change it through locale selector. The rest of
translations are behaving correctly. Any clue about what's happening with
translations outside of views and templates files?

Thank you in advance

Isaac

Re: i18n issue with compilemessages

[Isaac XxX]

The problem seems to come from your python path, that is not well defined.

Try to define path in an absolute (not realtive) fashion.

import os

os.environ['PYTHONPATH'] = '/path/to/myproject'
os.environ['DJANGO_SETTINGS_MODULE'] = 'myproject.settings'

and then, apache should be able to execute compile messages

Greetings,

Isaac

How to work with views like classes

[Isaac XxX]

Hi folks,

Currently i'm getting trouble with a single feature in django. When i've
some inheritance in templates, like the following

TemplateA

TemplateB inherits A

TemplateC inherits B
TemplateD inherits B

If I need to define something depending on provided data in TemplateA or
TemplateB, then all views that render TemplateC and TemplateD should provide
the needed data. For example

Template A
...
{% my_var %}
...

How can define "my_var" as global variable for all views that would render
an inherited template of A (or B, or whatelse needed) without recurring to
middlewares?

I've have programmed many time in RoR, and is really simple to define global
vars, or complex inheritance patterns to share common data.

BTW, I though about decorators, implement some "pre-post" processment, but
it's not as clean as i want, because I should get the specific context
(normally RequestContext, but it can be another one in other projects)
rendered by view.

Thanks in advance

Re: How to work with views like classes

[Isaac XxX]

Thanks for your responses.

The problem here is that there are some "dirty" solutions to this problem,
but i'm sure there is a good way to proceed with it.

This issue should be really simple to resolve if django make use of classes
instead of functions for views, and then, template would be benefited
receiving that class as parameter, using all provided data from that class
(and its superclasses).

Anyway, I think the django solution to accomplish it is to use middleware
nowadays, like i18n or authentication django plugins do.

Selecting a shopping cart

[Isaac XxX]

Hi there,

Recently I decided to develop a project that will involve some shopping cart
capabilities (we will sell some products, mainly by using credit card
payment methods).

I've been checking some packages - frameworks, and I can decide wich is
better fit for me. By now, I visited the following:

- LFS: Not a bad choices, but I found it a bit hard to be customized.
- Satchless: Maybe an early stage
- Satchmore: Seems a good choice, but still beign a framework. Maybe an app
is better fitted for me.
- DjangoShop: Seems that people are developing it to be a django built-in,
and it can be an interesting point to use it. However, there is not good
documentation / examples about its use and capabilities

By the way, I wish that selected package offer me a really deep level of
customization, but giving an inicial ready-to-use base to be started from.
Something like LFS do (only install framework and initialize db, and then
you have a shop ready), but being able to customize it in the way I want
(use or not portlets, use custom templates for whole / part of web, activate
shopping cart only in parts of the given web site...)

Thanks in advance,

Greetings

E-Commerce - Payment

[Isaac XxX]

Hi folks,

after some time spent in investigating django solutions for shopping carts,
i got satchmo as my one. I've developed a custom shopping cart, and this app
is ready to be published. The problem arised when I started to look for some
information about how to manage payments: all information is abstract and
nothing concise. By now, I only want to manage credit card payments
directly, bank transfers and maybe a paypal alternative.

Paypal seems to be clear at how to manage, but I don't know really how to
manage credit card data: can be stored? shall I transfer directly that ssl
channeled data to my bank? shall I manage it handly?
A good documentation source is really wellcome.

I know it is a transversal issue to django, but by now I don't know where to
ask it.

Thanks in advance

And then, some advice at how to manage "credit card gateways"? or some

Sorry if this is a beginner question, but is my first e-commerce
application, and had never deal with payments and credit card information.

Having issue sending email when model is save and not updated.

[Isaac Imafidon]

Am working on an ecommerce project and i want to be able to do two things 
before the model save .
1) I want to update the cost of an item
2) I want to send two  email to the receiver . One when the object just 
gets created while the other when the object gets updated. 
I go through django documentation about pre_save signal and post_save 
signal but don't really understand it.

This is my model
  
class Item(models.Model):
# set of possible order statuses
ITEM_STATUSES = (('PICK UP','PICK UP'), #default
('IN TRANSIT','IN TRANSIT'), # To let ur customer know their order 
is now been process
('DELIVERED','DELIVERED'),#Now delivered to them

)
cost = models.DecimalField(max_digits=10, decimal_places=2)
sender_name = models.CharField(max_length=150)
sender_email = models.EmailField()
receiver_name = models.CharField(max_length=150)
receiver_email = models.EmailField()

Before this model is save i want to update the cost by adding 10% of the 
cost variable to create a new cost that will be shown in the view also i 
want to send email to receiver_email  variable. Once the user update the 
model i want to still add my 10% to the cost and instead of sending email 
one, i will send email two. 
Something like this 

Model as before
if just_created :
   update the cost by 10% before save to the database
   send email 1 carrying the new cost variable and the receiver name to 
receiver email
   then save()
else:
   update the cost by 10% before saving to the database
   send email 2 carrying the new cost variable and the receiver name to 
receiver email
   then save()

Please guys i really need your help in this.

I think there's a problem with your database. Try deleting your dbsqlite
database and run migrations a again.

If I send a request to an invalid URL, the NEXT request sent to that URL is
