Re: De-serialization of ManyToManyField

[sk]

Hi,

I finally worked out where the problem was!

I am posting the answer in case that someone else has a similar issue
and stumbles upon this.

So I have reverted to the original model, as defined in the first
email here. The problem was with my definition of the natural keys, my
function was not retruning a tuple.

The solution was to add a comma to the return value of the natural_key
methods:

---
from django.db import models
class TestManager(models.Manager):
def get_by_natural_key(self, name):
return self.get(name=name,)


class Test(models.Model):
name = models.CharField(max_length = 100, unique = True)
date = models.DateField()


def __unicode__(self):
return self.name


def natural_key(self):
return (self.name,)


class InstanceManager(models.Manager):
def get_by_natural_key(self, name):
return self.get(name=name,)


class Instance(models.Model):
name = models.CharField(max_length = 100, unique = True)
test = models.ManyToManyField(Test)
date = models.DateField()


def __unicode__(self):
return self.name


def natural_key(self):
return (self.name,)

I realise this is a pretty basic Python 'gotcha' and one I would hope
I would normally spot! In this case I was just not sure where the
problem was.

I hope this helps someone else with the same problem, at some point!

regards
Stephen

After creating the user, I can verify that user.is_active is in fact

Any thoughts?


Yes: You have to call user.save() after creating it. Otherwise the user 
object exists, but it isn't saved to the database yet. And 
"self.client.login()" queries the database, not user objects local to 
the test.



Creating model objects in tests and testing them afterwards is something 
that needs a bit of care. I've made several mistakes with them already 
:-) Look at [1] for an example error.

Re: TestCase Client.login() fails

[jondbaker]

Problem solved. I forgot that .create_user will create and return a hashed 
password, which obviously won't work if said returned object password 
property is entered into the password field of the login form.

To make things easier, create a free host redirect on no-ip.org[1] and name
it something like 'mydjangoserver.no-ip.org', then install the No-IP
service for automatically updating the redirect to match your current IP
(on a defined interval, which I usually set for 30 mins). This way you can
always point to http://mydjangoserver.no-ip.org regardless of which network
you're currently on. Helps if you're on the go often, or if you've got a
dynamic IP (my original problem back when I started using it).

Re: TestCase Client.login() fails

[Alexey Kinyov]

Hello, Jonathan!

I think issue is in the fragment 'password=user.password' in the line:

>         response = self.client.login(username=user.username,
> password=user.password)

'user.password' - is not plain text password, it's encrypted and it's
not equal 't3stp@s$' !

Hello, Reinout!

That' wrong.

Documentation says:

create_user(username, email=None, password=None)

Creates, saves and returns a User.

https://docs.djangoproject.com/en/1.4/topics/auth/#django.contrib.auth.models.UserManager.create_user

I think the problem is that 'user.password' is hashed value but
login() method receives raw plain text password, as I answered above.

That' wrong.

Documentation says:

 create_user(username, email=None, password=None)

 Creates, saves and returns a User.


You're right, I was wrong :-)  I overlooked that create_user is a 
special call and thought it was just a generic create statement.

However, the error comes from BaseForm's clean method, which expects a

Re: Need help creating model.

[Psamathos]

I would create a many-to-many relationship between Student and Class 
through a custom intermediate model called Grade. You can then add a date 
field to Grade and any other extra fields you want.

Read up on m2m relationships here: 
https://docs.djangoproject.com/en/dev/topics/db/models/#many-to-many-relationships

Basically, you want to add a field to Student like

classes = models.ManyToManyField(Class, through='Grade')

Then add a new model like this:

class Grade(models.Model):
student = models.ForeignKey(Student)
class = models.ForeignKey(Class)
grade = models.IntegerField()
date = models.DateField(auto_now_add=True)

comparing custom template tag within if tag

[Nikhil Verma]

Hi all

i have a custom template tag that takes some argument and calculates the
result.
I want to compare that value obtained from that custom tag with another
variable.

Custom template tag
{% price_for_pax service pax '' %}

variable :

{{service.price}}

What i want is {% if service.price == price_for_pax service pax ' ' %}
   do something
 {% endif %}

When i look for the result it does not show anything
Can i compare like this ? If not what can be the solution ?

Thanks in advance

Re: Http404 and process_exception

[Justin Holmes]

Russell,

Thanks for the reply.

Two reasons:

1) Up until now, I hadn't encountered a 404 that had triggered this
particular process_exception.  It hadn't occurred to me that since
get_object_or_404 actually raises the Http404 exception that the behavior
was going to be different than, say, a try block whose exception clause
returned HttpResponseNotFound.

2) Once I had encountered this phenomenon, a quick google search led me to
this page from the book:

http://www.djangobook.com/en/beta/chapter16/

which seemed, at least for a moment, to verify my previous experience.

I think though that I simply hadn't raised Http404 since implementing this
middleware.  It makes perfect sense that it behaves the way it does.

Hosting tutorials

[Jak]

Hello All,

I am new to programming, and I have spent the year learning HTML, CSS,
Python, and now Django. I can build a basic dynamic site on the
development server, but I have no idea how to share this site with the
world. The Django deployment section in the Django book is difficult
to understand. What do I need to know before I can begin hosting my
projects. Do I need to know apache? I'm not even entirely sure how
servers work. I read the w3schools sever tutorial, but it only
describes what a server is, not how or what you need to host your
site. Does anyone know of any good tutorials for beginners?

Thanks

django.contrib.auth.views.login no response

[jondbaker]

I'm trying to build a login form by following the instructions on this page 
https://docs.djangoproject.com/en/dev/topics/auth/#django.contrib.auth.views.login.
 
The form is rendered in the template with a username and password field, 
but the hidden "next" field has no value, the form does not return error 
messages and there's no response on submit. Here is my code:

*urls.py*
urlpatterns = patterns('',
url(r'^accounts/login/$', 'django.contrib.auth.views.login', {
'template_name': 'accounts/login.html'
}
)

*templates/accounts/login.html*
{% extends 'base.html' %}
{% load url from future %}

{% block content %}

{% if form.errors %}
Your username and password didn't match. Please try again.
{% endif %}


{% csrf_token %}

{{ form.username.label_tag }}
{{ form.username }}


{{ form.password.label_tag }}
{{ form.password }}

Re: Hosting tutorials

[NENAD CIKIC]

Hi,
i am also new to django. I have put alive my first django project on
linode VPS.
First I have created on my development machine the virtual box with
last ubuntu. Then I have put alive the django project following
instruction on
https://code.djangoproject.com/wiki/DjangoAndNginx
i.e. I have used nginx as it seemed from newgroup posting easier to
install for newbies.
After I have done it on vbox I have bought linode account and repeated
the sequence there.

All in all, in two days I have put the project alive. Probably not all
is done as it should be, but it is live.

The most time I have spent is on how to share the folder between vbox
and windows host. The not documented hint (at least i did not find
anywhere) is that the root user of ubuntu shall be part of vboxusers
group, so I have created the group with
groupadd vboxusers
and added the user to the group
sudo usermod -a -G vboxusers cikic
After that I could use the vbox additions; i.e. I could map one folder
for data exchanging.

Re: Hosting tutorials

[yati sagade]

Hi
I you just want to share your apps with the world, you do not need to pay
for a complete server setup. I have been using OpenShift(
https://openshift.redhat.com/app/) for long now, and it's quite easy to get
up and running. Others are[not tried, but heard are great] Heroku(
http://www.heroku.com/), Google AppEngine(https://appengine.google.com/).
I've actually used GAE for Python, but using Django and it's ORM is a bit
tricky here, but nonetheless doable. Another one with great reviews is
CloudFoundry by VMWare (http://www.cloudfoundry.com/).

Cheers!

Re: Django With Tweepy

IntegrityError at /register/ auth_user.username may not be NULL

[laurence Turpin]

I'm getting the following error with my registration  section of my
program.

IntegrityError at /register/
auth_user.username may not be NULL

I am using django 1.3.1 and python 2.7.2 and I'm using sqlite3 as the
database.
I am a newbie and I'm learning Djanogo from the book "Learning website
development with Django"

The registration form is displayed ok  and I'm able to fill it out and
it is when I click register that the problem occurs.

///

My views.py  looks like the following and register_page is the
relevant function here:

///

from django.http import Http404
from django.contrib.auth.models import User
from django.shortcuts import render_to_response
from django.http import HttpResponseRedirect

'main_page.html', RequestContext(request)
)

def user_page(request, username):
try:
user = User.objects.get(username=username)
except:
raise Http404('Requested user not found')

bookmarks = user.bookmark_set.all()
variables = RequestContext(request, {
'username': username,
'bookmarks': bookmarks
})
return render_to_response('user_page.html', variables)

def logout_page(request):
logout(request)
return HttpResponseRedirect('/')

def register_page(request):
if request.method =='POST':
form = RegistrationForm(request.POST)
if form.is_valid():
form.user = User.objects.create_user(
username = form.cleaned_data['username'],
password = form.cleaned_data['password1'],
email = form.cleaned_data['email']
)
return HttpResponseRedirect('/register/success/')
else:
form = RegistrationForm()
variables = RequestContext(request, {
   'form': form
})
return render_to_response(
   'registration/register.html',
   variables
)

///

My forms.py  is the following:

///

from django import forms

from django.contrib.auth.models import User
from django.core.exceptions import ObjectDoesNotExist

class RegistrationForm(forms.Form):
username = forms.CharField(label="Username", max_length=30)
email = forms.EmailField(label='Email')
password1 = forms.CharField(
label='Password',
widget=forms.PasswordInput()
)
password2 = forms.CharField(
label='Password',
widget=forms.PasswordInput()
)

def clean_password2(self):
if 'password1' in self.cleaned_data:
password1 = self.cleaned_data['password1']
password2 = self.cleaned_data['password2']
if password1 == password2:
return password2
raise forms.ValidationError('Passwords do not match.')

def clean_username(self):
username = self.cleaned_data['username']
if not re.search(r'^\w+$', username):
raise forms.ValidationError('Username can only contain
alphanumeric characters and underscores')
try:
User.objects.get(username=username)
except ObjectDoesNotExist:
return username
raise forms.ValidationError('Username already taken. ')

///

my register.html looks like the following:

///

{% extends "base.html" %}
{% block title %}User Registration{% endblock %}
{% block head %}User Registration{% endblock %}
{% block content %}
{% csrf_token %}
{{ form.as_p }}


{% endblock %}

///

I hope somebody has an idea of what the problem is all I know is it's
something to do with the database.

The exception location is:
C:\Python27\lib\site-packages\django\db\b

Looks like you have an indentation problem in clean_username - the lines 
under the first "raise forms.ValidationError" should be one level to the 
left, otherwise they will never be reached and the method will never return 
the cleaned value for username.

Re: Django With Tweepy

[Python_Junkie]

Interesting question.

I would have to think about your larger question, but the smaller issue, is 
that you need to close the crsr and you need to commit, 

I would think that you would not want to make commit automatic, so that 
your code has a chance to do some error checking and perhaps roll back.

Tweepy Not Displaying

[coded kid]

Hi guys, I want to display user’s timeline in my django app but it’s
not working. It only display a white blank page! I’m using Tweepy.
Below are my codes:

Views.py

import tweepy

def tweetstream(request):
consumer_key=""
consumer_secret="XXX"
access_token="XXX"
access_token_secret=""
auth=tweepy.OAuthHandler(consumer_key, consumer_secret)
auth.set_access_token(access_token, access_token_secret)
api=tweepy.API(auth)
status=api.user_timeline()
for status in status:
if status:
status.__getstate__()
return render_to_response('tweet.html',
context_instance=RequestContext(request))

Template:
{% extends "base.html" %}

 {% block content %}

 {% for status in status %}
   {% if status %}
{{ status.author.screen_name}} {{status.text}}
{{status.source}}

{% endif %}
 {% endfor %}


{% endblock %}

What I’m I missing? How can I make it return user’s timeline?

strange problem deleting objects

[Marc Aymerich]

Hi!,
I've overrided the save() method of one of my ModelForms and I'm
performing a delete of some related objects depending on some form
fields values. The thing is I'm getting differents behaviours
dependening on how the deletion is performed, consider:

1) self.instance.delete()
2) MyModel.objects.get(pk=self.instance.pk).delete()

I'm listening the post_delete of self.instance class, in there I
create a "dependency graph" of their related objects. The problem is
that at some point I'm retriveing self.instance like:
MyRelatedModel.self_instance_related_name and with the first (1)
delete method I can still access to self.instance but with the second
(2) delete method i'm getting a DoesNotExist.

Why it's different?

Thanks!

Yes - that does seem to suggest 404's don't trigger exception middleware. 
However, I've checked the code back to the magic-removal merge (in 2005) [1], 
and I can't see any evidence that 404's have ever been a special case. 

[1] 
https://code.djangoproject.com/browser/django/trunk/django/core/handlers/base.py?rev=2809#L73

The only change to this area that I can see is to make sure that the response 
raised by the exception middleware is in recent times has been a modification 
that means that if the exception middleware returns a response, that response 
goes through the response middleware; back in the days of magic-removal, it 
would be returned verbatim.

Yes and no; yes, in that it's an exception; no, in that it's an interesting 
inconsistency that 404s are (or can be) handled as exceptions, but no other 
status code is handled as an exception.

That bit looks like it might cause trouble.  You are assigning status to 
status.  Normally you'd want something like...

{% for status in statuses %}

or

{% for status in status_list %}

or

{% item in status %}

Use whatever variable names you want as long as you're not clobbering 
variables that are needed while looping.

Cant get spatialite and pysqlite working

[Jak]

We have a Django aplication which depends on Spatialite and Pysqlite.
It works well for testing under Ubuntu, but when we try to install it
on the server, we are getting the following error after installing
PySqlite. We did set it up with define=OMIT_SQLITE_LOAD_EXTENSION
commented out:
django.core.exceptions.ImproperlyConfigured: The pysqlite library does
not support C extension loading. Both SQLite and pysqlite must be
configured to allow the loading of extensions to use SpatiaLite.

What could be causing this?

Re: Django With Tweepy

[Python_Junkie]

I believe he means using the Object Relational Model  ORM, which is an API 
abstraction for several frameworks.

Whether you use sql or the ORM (you can learn more about the ORM on the 
django project tutorial) only clouds the issue that you are trying to answer

SQL is SQL whether you make an abstraction layer or not

Re: Auth app in separate database

[Amit]

While running syncdb command django uses default database to create
tables.
You can do one thing, first create default database using syncdb then
copy auth related tables to another database.
Then define router for auth. You can get more ref form django
documentatiion.

Amit
