Css and Images are missing

[Luis Goncalves]

Hello guys I need your help in here.

Sorry I am new in Django and I am having a problem, my css and jpgs
are missing.

I will write everything what i have and then maybe someone could give
me a hint :)


My settings.py:
MEDIA_ROOT = '/home/lgoncalves/Arquivos/MyVitaminesShop/media/'
MEDIA_URL = 'http://127.0.0.1:8000/media/'
ADMIN_MEDIA_PREFIX = '/media/'


My urls.py:
(r'^media/(?P.*)', 'django.views.static.serve',{'document_root':
'settings.MEDIA_ROOT'}),


And an example of base.html:
http://127.0.0.1:8000/media/
mm_health_nutr.css" type="text/css" />
http://127.0.0.1:8000/media/picture.jpg"; alt="Header image"
width="382" height="101" border="0" />


Thanks so much for your help.

Best Regards,

Luis

Re: Css and Images are missing

[Luis Goncalves]

Well i saw this:

"With that said, Django does support static files during development.
You can use the django.views.static.serve() view to serve media files.
The big, fat disclaimer¶

Using this method is inefficient and insecure. Do not use this in a
production setting. Use this only for development.

For information on serving static files in an Apache production
environment, see the Django mod_python documentation.
How to do it

Here’s the formal definition of the serve() view:

def serve(request, path, document_root, show_indexes=False):

To use it, just put this in your URLconf:

(r'^site_media/(?P.*)$', 'django.views.static.serve',
{'document_root': '/path/to/media'}),
"
So there is support on development... And i have that on my urls.py...

So i still dont understand why doesnt work,

Thanks,

Re: IDE

[luis cota]

I used to use Eclipse + PyDev - good setup, though extremely bloated.  Now I
use Komodo Edit (OpenKomodo) for my python coding.  Good autocomplete
support, much lighter than Eclipse and cleaner UI.

Good luck,

Problem loading a js file

[Luis Gustavo]

I am trying to use the calender code I found in
http://www.dynarch.com/projects/calendar/
in my form template, with a generic view.  I have copied the script
files to many places in my project and tried different configurations
in settings, but I always get the same error, Calendar is not defined.
My template starts with

@import url(calendar-win2k-1.css);





and has the date field

start: {{ form.data }} ...

  Calendar.setup(
{
  inputField  : "id_data", // ID of the input field
  ifFormat: "%m %d, %Y",// the date format
  button  : "trigger"   // ID of the button
}
  );


as described on the script site. What is wrong?

Very nice site. Just to let you know though, I found one bug.
Clicking on the Login button without entering anything gives me an

an http 500 error)

Hi Syhpoon,

I'm not too familiar with the captchas, but shouldn't you use the
template tags {% load captcha %} and {% captcha %} instead? The leading
and trailing spaces are important, I think.

Re: How to get the Exception Type

[Luis Gonzalez]

Hi as you can see here at http://docs.python.org/tutorial/errors.html
in 8.3 handling exceptions theres a piece of code that works as you
want.

for example try this:

try:
  int("a")
except Exception as e: #The key is using "as" and the variable name
you like for retrieving the exception because if you dont you will
only get
   #"Exception type" type

  print type(e) #This will give de exception type. In this case #'
  print e #This will print you the message exception.  #invalid
literal for int() with base 10: 'a'
  print e.message #This would give you the string message #invalid
literal for int() with base 10: 'a'


I hope this can help you, please forgive me for my grammar im mexican.

Re: View decorator for common navigation elements?

[Luis Morales]

wouldn't a template tag work best in a case like this?

something like {% NavBar %} or {% GetNav NavName %}

that way you can have your own cache code inside you template tag
code, like storing the database result into memcached or redis and
avoid a relational db call each page. them you you modify you
navigation data model you can you invalidate the cache and recreate
it. it will also be a lot simplier to reuse in other projects as you
wont have to inlcude a decorator on each view.

pyodbc.connect timeout question

[Luis Tavera]

Hi all,

I have some code similar to the one below that runs slightly differently if
I run it outside Django and within Django. The difference is that within
Django it takes much longer to raise the pyodbc.Error (several minutes)
than outside Django (a few seconds). I am new to Django (and Python) and I
wonder why this may be happening.

Any hints will be appreciated.

thanks,

Luis

Re: post_save signal not working in Django 1.7

[Luis Matoso]

Something similar is happening with me too: on a post_save of model it 
isn't created yet on database, so several 
error are raised by functions which expect that it is already on DB.

When the post_save handler ends, the object is saved normally.

Problem with sitemap.xml in django project.

[José Luis]

I am deploying a Django project with Gunicorn + Nginx. I create a 
sitemap.xml file with the sitemap framework 
. I use a 
127.0.0.1:8001 proxy so when i access to example.com/sitemap.xml the result 
is similar to this:






http://127.0.0.1:8001/service/item/gestionar_apertura_de_academia

monthly
0.5



When i add sitemap.xml to the Google index in Google Webmaster Tools, 
Google does not allow the sitemap.xml because the domain in location tag is 
127.0.0.1:8001 and not my domain.

Is there any solution to this problem?

I've posted this question in StackOverFlow too: 
http://stackoverflow.com/questions/28263869/sitemap-xml-file-in-django-gunicorn-nginx-web

Thank you so much for your help

Migrations force me to have, forever, any name/reference I use in field validators=, choices=, whatever, valid forever (even if the requirements change).

[Luis Masuelli]

I have an issue with migrations.

Suppose I declare (in my application, with name myapp) a field with a 
validators= declared. In such value (which is an iterable), I declare a 
function:

class MyModel(models.Model):
"""
This one is identifiable.
"""

identifier = models.CharField(max_length=10, unique=True, validators=[
valid_identifier])

Assume I created the migration with makemigrations:

# -*- coding: utf-8 -*-
from __future__ import unicode_literals

from django.db import models, migrations
from django.conf import settings
import django.core.validators
import micnt.models


class Migration(migrations.Migration):

dependencies = [
...
]

operations = [
migrations.CreateModel(
name='MyModel',
fields=[
('identifier', models.CharField(max_length=10, unique=True, 
validators=[myapp.models.valid_identifier])),
],
options={
},
bases=(models.Model,),
),
]

Assume valid_identifier is any external callable which will take one 
positional argument, and eventually raise ValidationError under certain 
conditions.

Now the requirements vary: The identifier may be national or foreign, so 
the country is required as an additional field, and also a discriminator 
field. Additionally, the validation I must perform is cross-field, so 
instead of using something in validators, I define a clean() method, and 
make the combination of country/identifier unique, instead of just the 
identifier unique:

class MyModel(models.Model):
"""
This one is identifiable.
"""

identifier_type = models.CharField(max_length=10, choices=(('passport', 
_(u'Passport')), ('national', _(u'National'))), null=False)
identifier = models.CharField(max_length=10)
country = models.ForeignKey(Country, null=False)  # assume Country 
model exists

class Meta:
unique_together = (('identifier', 'country'),)

def clean(self):
raise ValidationError('Implement this!')


And then, I don't need anymore the valid_identifier function, since my code 
does not use it anymore. So I delete it.

Now I will create the migration with makemigrations as usual. What will 
happen?

a. The command will succeed.
b. The command will explode (i. e. a normal Python exception).
c. The command will create an inconsistent migration, without exploding.
d. Jesus will come again.
e. The command will get into a kind of endless loop.

If you guesses "b", you were right. Django will report an error, since 
myapp.models.valid_identifier does not exist anymore (AttributeError).

So, once I set a value for validators= parameter and create a migration, I 
am forced to keep such reference valid for the rest of my life (e.g. by 
having valid_identifier=None, if I don't need the function anymore), or 
else the migrations will not work again since they will be traversed, 
imported, and will get such AttributeError.

Is this an expected, normal, behavior?

[Luis Masuelli]

Thanks :D Did not think about squashing migrations as solution for this 
problem! But it does the job.
OTOH the fact about historical models has nothing to do with my problem 
(since it is not related at all with instancing a model, but just about the 
definition and not getting a NameError).

Re: Using proxy kind of Table in Admin Interface

[luis zarate]

Maybe you can use get_queryset in the admin class and replace the query
manager

ref:
https://docs.djangoproject.com/en/1.7/ref/contrib/admin/#django.contrib.admin.ModelAdmin.get_queryset

https://docs.djangoproject.com/en/1.7/topics/db/managers/

you can do something like this:

def get_queryset(self, request):
"""
Returns a QuerySet of all model instances that can be edited by the
admin site. This is used by changelist_view.
"""
if request.user.is_superuser:
qs = self.model.superuser_manager.get_queryset()
else:
qs = self.model._default_manager.get_queryset()

ordering = self.get_ordering(request)
if ordering:
qs = qs.order_by(*ordering)
return qs

Re: Form In modal

[luis zarate]

Fast solution:
In Javascritp you can do this:

element = document.getElementById("myinput");
window.open("http://127.0.0.1:8000/consulta/?consulta="+element.value,
"MsgWindow", "width=200, height=100");


but continue reading


Are you use ajax?
If the answer is not, then see https://github.com/yceruto/django-ajax.

A concept problem is there, modal is a interface view (in the browser) and
your method refresh the page (It is a GET Request).

I don't know what kind of framework you are using, but in general you can
do something like this:



Operadora  Tipo
CLAROMOVEL



$("#mymodal").modal();




for more information see
http://getbootstrap.com/javascript/#modals
http://jqueryui.com/dialog/

PD: You can do better implementation if you are using django ajax

Re: Django OperationalError

[luis zarate]

If you deleted your db and created again and the issue persist then maybe
the problem is in your apps.

Try removing db, comment 3th party apps in settings and run migrate with
only django core apps, put again 3th party apps and run migrate.

 Hi Petar,
 I'm actually not sure why you want to call sqlflush. If you're trying
to clear out the database, you may need to delete the migrations table
manually, but it just might be simpler to delete the either database and
re-create it, rather than the individual tables.

Re: django beginner

[luis zarate]

what is the output of django-admin --version ?

Instructions:
 1) open cmd
2) change your current directory to your work directory
3) run django-admi --version
4) copy and paste the output  here.

The output will be like "1.7.2"

Re: django beginner

Your python configuration is ok. so I guest you have someone of this
problem.
 - Your work path has spaces and python confuse with them.
 - Your system mimetype for .py use notepad++ for open it.

I don't know if this solve your issue but I think that check this prevent
you a headache

I test doing a simple project and this is my result.

$ django-admin startproject mysite
$ tree

Internationalization to 3rd party Django apps

[Luis Masuelli]

I use django-rest-framework==3.0 in an application as an example case (*) 
of what I am talking about. Most of the messages in DRF are not 
internationalized, and had to use the following mechanism to create the 
internationalization for DRF messages:

   - Properly set LANGUAGES and locale directories, so `makemessages` knows 
   where to store the generated messages.
   - Add a symbolic link into my django root directory, pointing to the 
   directory being the rest_framework package (in site-packages).
   - Running `makemessages` adding the `--symlinks` options, so the 
   rest_framework would be inspected as well as the regular (project-wise) 
   applications are.
   - Removing the symbolic link I created, from my django root directory.
   
Finally, assuming the global locale dirs are set accordingly, I get the 
messages being generated for the desired locales (i.e. I only have to edit 
the .po files with the appropiate translations).

I don't like this method. Looks ugly. Isn't there another method to grab 
ugettexted messages from 3rd party applications and add them to django.po?
(* Please: don't attend my problem in terms of DRF since I could have 
another issue with another application and would need to ask the same 
question again)

Re: authenticate() not working

[Luis Zárate]

It's because you need to login the user (authenticate don't login only get
the user )

It's something like this:

from django.contrib.auth import authenticate, login
def my_view(request):
username = request.POST['username']
password = request.POST['password']
user = authenticate(username=username, password=password)
if user is not None:
if user.is_active:
login(request, user)
# Redirect to a success page.
else:
# Return a 'disabled account' error message
...
else:
# Return an 'invalid login' error message.
...

Re: Adding admin access for external users

[Luis Zárate]

Are you deploy your application ?
https://docs.djangoproject.com/en/1.8/howto/deployment/

It's important *Don't use development environment in production apps!!!*

It's simple to login user in admin site, create a user and check the *is
staff* option and set the user permissions. ( site admin chech user
permission and show only the models that the user has permission so if the
user don't has one he can't view nothing)

Re: Upload above apache web root?

[Luis Zárate]

Hi,

Django provide for development MEDIA_URL and MEDIA_ROOT for uploaded file,
for production used static deploy strategy, see the documentation about
static files.

Model file field has an url attribute that return a media url, you use in
template like {{obj.file.url}}

You still need an actual URL that is served by your webserver. Obviously, a

Re: Upload above apache web root?

[Luis Zárate]

You are not set base_url in FileSystemStorage so you are using MEDIA_URL by
default.

The imagefield url property is called like this

def _get_url(self):
self._require_file() # check if It is an object
return self.storage.url(self.name)
url = property(_get_url)

And self.storage.url throw exception if base_url is not set.


def url(self, name):
if self.base_url is None:
raise ValueError("This file is not accessible via a URL.")
return urljoin(self.base_url, filepath_to_uri(name))

So, I should try to call datamine.image.url() in shell and see what happen

[Luis Zárate]

Other thing that I forgot in the last mail is how use function now()

Wrong solution

from datetime import datetime
datetime.now()

Good solution

from django.utils import timezone
timezone.now()

Re: Model with two e-mail fields uniques

[Luis Zárate]

I don't know if work with many to many is the best approach, because if you
know that only have two emails for user and you check his email a lot then
the cost of join in time and machine resources increase innecessarily  So
knowledge of you requirements determine your db scheme.

Using the first solution I thing in something like this.
in models.py

class Person(models.Model):
first_name = models.CharField(max_length=100)
last_name = models.CharField(max_length=100)
email1 = models.EmailField()
email2 = models.EmailField(null=True, blank=True)



in your forms forms.py

from django.forms import ModelForm
from myapp.models import Person

class PersonForm(ModelForm):

def clean(self):
cleaned_data = super(PersonForm, self).clean()
if cleaned_data['email1'] == cleaned_data['email2']:
raise forms.ValidationError("Emails are equals ")




class Meta:
model = Person
fields = ['first_name', 'last_name', 'email1', 'email2']


And if you want to use in admin site

class PersonAdmin(admin.ModelAdmin)
form = PersonForm


2015-04-08 9:01 GMT-06:00 Bruno A. :

 it's a very bad idea to have plurality by adding a number of similar
 fields.  instead, you should have a related table

 class Person(models.Model):
 first_name = models.CharField(max_length=100)
 last_name = models.CharField(max_length=100)

 class Email(models.Model):
 person = models.ForeignKey(Person)
 email = models.EmailField(unique=True)

Grouped Select in admin django

[Luis Salvay]

I have a model "Company" having many to many relationships with Country and 
City while country and city have one to many relationship between them. The 
problem is that when loading an "enterprise" have to select the countries 
atienede the company and the cities they serve, but the list of cities is 
very long and also the cities are all mixed without distinguishing what 
country you are. What I'd like is to group the cities by country. It is 
exactly what django-smart-selects, only this plugin does not work in many 
to many relationships. Someone could help me adapt this plugin to work with 
many to many relationship or comment me if they think of another 
alternative. Thank you very much!

Re: django 1.8 and wsgi_mod

[Luis Zárate]

Your server log said this (loading my.wsgi)
Exception occurred processing WSGI script
'/code/projects/my_web/wsgi/my.wsgi'.


But your structure said that wsgi file is called different (idrac.wsgi).

Other thing, call core your app is not a good idea, do it if you understand
well how python import work, otherwise it is a pain in the ask

Re: NoReverseMatch at /polls/1/results/

[Luis Zárate]

Which urls.py you paste here? The project URLs or the app urls .?

It is because you are using namespace in the url reverse so you need to
named in your project's URLs and put the code paste here in your app urls.

Re: Kivy and Djangp

Take a look at this http://kivy.org/docs/api-kivy.network.urlrequest.html
for Kivy
and http://www.django-rest-framework.org/ for django.

You need to do a web service with django I suggest a restfull service and
with kivy urlrequest create a client.

Re: change the style of the forms been render in the httml?

[Luis Zárate]

It is easy, you only need to put id attribute to form statement like this

 {{form.as_p}}

In CSS use cascade starting by #myform.

Other thing I was used form.as_p for printing as , but you could used
form.as_ul or form.as_table too.  By default as_table is set when you do
{{form}}

httml form to django

[Luis Zárate]

You don't need to alter any model, only need to create a form class
(better) or using request.POST.get("username").

If you want to do in right way
See

Re: Django formset hidden id field

Mmm I am not sure of this but I guest that this number is not a primary key

forms in correct order also)

It has to be updated by a form. To make it a correct django form there is a
hidden field with the CSRF token. This protects the database being updated
from any illegal source.

 Hello,

 I have a formset and when I render it, Django would include this line
in the HTML:

 

 I am curious what is the purpose of having an id field here.

 I mean in what situation would you use it. I did look through
Django's documentation on formsetbut cannot find much documentation on this.

 One answer I got is that this id field is the value of the primary key
of the model bound to this form. It is there so that when the formset
updates, people can use it to retrieve the corresponding record from the
database.
 Is the above explaination correct?
 If this explaination is correct, then my next question is, wouldn't it
be dangerous to expose the primary key like that? I can make a post call to
your server with a modified pk which can mess up your database.
 Thank you!

Re: Help needed for big django project (crm+shop+cms+autoresponder). What apps shall I build on?

[Luis Zárate]

Did you serch for something like this https://www.*odoo*.com/, It is not
django but it is in python and  released under the AGPL license.

If you want to build your software stack based in django then start
searching in https://www.djangopackages.com/.


1. *CRM* system
 -> client database
 -> ticket system (client communication including sending emails from
backend)


 2. *Shop*
 -> calender booking system
 -> PDF billing generation
https://github.com/burke-software/django-report-builder

 3. email *autoresponder* system
 4. *CMS* functionality would also help


django-oscar is interesting software, take a look at
https://github.com/django-oscar/django-oscar

Re: No Email field in the User Registration Form

[Luis Zárate]

Where is your meta class ?

It is not in __init__() function, is it?
if it is then problem is there.

class Meta:
> model = CustomUser
> fields = ['email',]

del self.fields['username']

this is wrong, use exclude in Meta class to remove fields

SITE_ID = 1 in your settings.

Re: Best Queryset Practice

[Luis Zárate]

Querysets are lazy,  so Model.objects.all().filter(...) execute a same
query that Model.objects.filter(...).all()  and Model.objects.filter(...).
For check this tray  in shell

str(Model.objects.all().filter(pk=1).query)

str(Model.objects.filter(pk=1).all().query)

str(Model.objects.filter(pk=1).query)

¿Que tipo de búsquedas desea hacer?

Si son consultas en la base de datos puede usar el ORM de django para

Django 1.8 feature in 1.7.9?

[Luis Zárate]

Maybe you need to uninstall django first, clear pip cache and install again.

pip uninstall django==1.7.9
rm ~/.cache/pip/*# or wherever it is pip cache folder
pip install django==1.7.9

Knowing what we know now, I guess next time (hopefully there won't be one)
I will just roll a new version. If you think I should do that at this

Re: design decision tree survey using django admin interface

[Luis Zárate]

I know it is not the answer of your question but for your survey design it
is important that you see this links.

https://github.com/chrisglass/django_polymorphic

I know that because I did a survey app years ago, but unfortunately it is
not free and it is in spanish too.

Re: my mysite/templates/admin/base_site.html is ignored (tutorial unclear?)

[Luis Zárate]

Sory for not answer before, but I think I could help.

First you need to know how django find the templates, so take a look
template loaders

https://docs.djangoproject.com/en/1.9/ref/templates/api/#django.template.loaders.filesystem.Loader

There are two default loaders (filesystem and app )

['django.template.loaders.filesystem.Loader',
 'django.template.loaders.app_directories.Loader']

so take a look 
https://docs.djangoproject.com/en/1.9/ref/settings/#template-loaders

So is important the app order.

django middleware process exception not call

[Luis Zárate]

Hi,

I was working with middleware that catch exceptions and redirect to other
view depending of except type.

My idea was raise custom exceptions in several parts of the code and catch
in middlewaware with proces exception function, but I have an exception
raise in template tag when template is render and after process exception
call, so this function is never call.

I surft in django code an understand what happen but I thing that django
could call process exception if exception occurred in template o have some
way to catch template exceptions, something like a function named process
template exception.

Re: Displaying a document

[Luis Zárate]

Do you have a model  with a fileField?


I think you are wrong passing file to template, if  you have a model with
filefield you can use media url something like

class Mymodel(Model):
  myfile = models.FileField(upload_to="my_file_path_in_media")


so you can use a form

class Myform(forms.ModelForm):

 class Meta:
 model=Mymodel
 fields = '__all__'

so in the view you have

if request.method=='POST':
   form = MyForm(request.POST, request.FILE)
   if form.is_valid():
instance=form.save()


so you can pass instance in template context

   render(request, 'mytemplate.html', {'instance': instance}

in your template you can put a link or whatever you want.

Re: Hi - I'm new to Python and DJango

[Luis Zárate]

Sure,

It's good enough and more.

There is some development in ERP but nothing stable or usable (not that I
known).

So if you are interested in develop something could be great know about.

Note: I thing first step is search what programs exists and try to
collaborate with one, but if nothing is good enough then start with new
develop and look for help.

Re: Why is my Django template not displaying?

[Luis Zárate]

Use  plays as a list in form.

You are passing context_list as context object so all variable inside
context_list are available in template but not context_list.

Other option is
return render(request,'live.html',
{"context_list": context_list})

You'll probably need Celery to process the commands for adding/removing
hosts from the backend and other management tasks.

Django should be able to handle (probably in combination with Celery).

Non Ascii character in upload file crash in python 3

[Luis Zárate]

Hi,

I am having this issue in server production, I developed with python 3
and with others fields work great but when file is involved I don't
know how to intermediate and remove non ascii characters.

Part of my stack trace is:

Internal Server Error: /vistapublica/perfil/editar

UnicodeEncodeError at /vistapublica/perfil/editar
'ascii' codec can't encode character '\xd1' in position 74: ordinal
not in range(128)

FILES:
foto = 

So, how can I fix this issue?.

Re: choices field language

[Luis Zárate]

Use in the first line

#- coding: utf-8
from __future__ import unicode_literals

And put in models



from django.utils.encoding import python_2_unicode_compatible

@python_2_unicode_compatible
class MyClass(object):
   def __str__(self):
   return "Instance of my class"

Re: Django urls.py reload (not from database)

[Luis Zárate]

I put all in urls and check permissions with

https://docs.djangoproject.com/en/1.9/topics/auth/default/#django.contrib.auth.decorators.user_passes_test

so if not

config.L7V_INITIALIZATED


I raise a 404 exception.

No need to reload urls.
