Simple Login Problem

2014-11-27 Thread Rootz 
I have a django app but I having problems with my login views and logout 
views. I do not have a html template designated to handle user login/logout 
view.
Django project is configured as follows:

INSTALLED_APPS 

 setting:

   1. 'django.contrib.auth' contains the core of the authentication 
   framework, and its default models.
   2. 'django.contrib.contenttypes' is the Django *content type system* 
   , which 
   allows permissions to be associated with models you create.
   3. 'django.contrib.sessions',
   
 MIDDLEWARE_CLASSES 

 setting:

   1. SessionMiddleware 
   

manages *sessions* 
    across 
   requests.
   2. AuthenticationMiddleware 
   

 associates 
   users with requests using sessions.
   3. csrf.CsrfViewMiddleware 


Using Django Template Language and Template inheritance. The login form is 
on the base template on other templates extends from this base template.

All my login attempts result in some of the views rendering the user info 
(username to welcome user back) while other views rendering the page as if 
the user is an anonymous user. If I try to login in again I get an error 
page stating that there is a missing csrf token or incorrect. Adding to 
this I have identified many instances where I have tried to logout and it 
does not seem to log me out because it is still showing the last user login 
info. For my base template I have hard coded the form (meaning not using 
Django Form class).

Can You identify the possible fault in how i am implementing the login and 
logout views?

 
 Here is a copy of my login and logout views

def members_login(request):

if request.method == 'POST':
password = request.POST['password']
username = request.POST['username']
user = authenticate(username=username,password=password)

if user is not None:
if user.is_active:
login(request,user)
return redirect('members:index')
else:
#inactive users required to re-register
return redirect('members:index')
else:
#no account required to register to create one
return redirect('members:register')

else:
#test if login is a regular get request then redirect
return HttpResponseRedirect(reverse('members:index'))


def members_logout(request):
logout(request)
return redirect('members:index')

Re: Does Django offers a way to generate data grid from database table like web2py

2014-11-27 Thread Sarbjit singh 
What web2py GRID does is, that it takes the SQL table/query as argument, 
and return the records satisfying the query. 

Records which are returned are seen in bootstrap enabled table with 
features having pagintation, sorting, search, ability to edit/delete/view 
individual record, add new record etc.

(See for link - web2py grid snapshot as well 

)

*What I want?*

I just wanted to have the end result similar to as of web2py grid where 
records (satisfying any query) can be seen inside a tabular form with the 
ability to search, sort, edit/delete individual record etc. 

Since, I am new to Django, I am not sure if Django provides such a thing 
out of box or any third party app provides this capability.

If you just click on web2py link above, snapshot of web2py grid will give 
you a clear idea.

Re: Test client to a redirect requiring a login doesn't set redirect_chain properly?

As a bit of follow-up information, if I use runserver and browse to
the view, it redirects me to /admin/common/region/add/ but it
displays as the login screen.  Am I missing why this wouldn't do a
redirect to my named login URL?

(this at least demonstrates that the test-client and browser/server
behavior is consistent; I'm just unsure why I'm not getting the login
url)

Thanks,

Test client to a redirect requiring a login doesn't set redirect_chain properly?

2014-11-27 Thread Tim Chase 
I have a view that can redirect to /admin/common/region/add/ but that
url (being an admin page) should require login (right?).  My test that
logs-in works as expected.

However, when I try to do an assertRedirects() without logging in
first, the assertRedirects() doesn't seem to follow through to the
login URL.

def test_no_region_not_logged_in(self):
# if we have no regions and attempt to visit
# the "home" page, the site has been misconfigured so
# it should redirect to the admin page (via login)
# where a new region can be created.

url = reverse("home") # the URL that
# should redirect to /admin/common/region/add/
# via the login page

# self.client is instantiated in setUp()
response = self.client.get(url, follow=True)

# print repr(response.redirect_chain)
# the redirect_chain contains just has one entry
# rather than the two I'd expect

add_region_url = reverse("admin:common_region_add")
login_url = reverse("login")
expected_url = "%s?next=%s" % (
login_url,
quote(add_region_url)
)
self.assertRedirects(response, expected_url)

However my test fails with:

  AssertionError: Response redirected to
  'http://testserver/admin/common/region/add/', expected
  'http://testserver/accounts/login/?next=/admin/common/region/add/'

Where am I going wrong?  Do admin pages not have @login_required as I
expect?  Does the test-client not fully follow when follow=True?

For what it's worth, this is Django 1.6.7 (I need something pre-1.7
because my hosting-provider's target environment only has Python 2.6,
not 2.7)

Thanks for any hints you might be able to offer.

Re: strange question when i access related object

2014-11-27 Thread James Schneider 
Try throwing in an event.save() after creating the eventdate_date. The
event.dates.all() is spawning a new query, and you are trying to list
changes that haven't yet been committed to the database.

Newbie help - running django-admin.py produces empty mysite folder

2014-11-27 Thread David Pride 
Title says it all really. Have just installed Django 1.8, can test django 
version and get correct response so am *fairly* happy it's installed 
correctly. I have had Python 2.7 installed and been using perfectly for 
several months. 

Altered the PATH variable as discussed so it points to correct directory. 

However when I run...

django-admin.py startproject mysite 

The mysite folder is created - but it is empty, none of the following is 
created...

mysite/
manage.py
mysite/
__init__.py
settings.py
urls.py
wsgi.py

All tips gratefully received!

Many thanks, 

D.P.

Re: Does Django offers a way to generate data grid from database table like web2py

2014-11-27 Thread Avraham Serour 
maybe you'll get a better chance of responding if you explained what this
web2py feature does exactly

currently you have a very low chance of getting a response because you need
from someone knowledgeable in both django and web2py.

What do you need? an html table with database data?

strange question when i access related object

2014-11-27 Thread daedae11 
My EventDate model has a ForeignKey to Event shown as follows:

class EventDate( models.Model ): # {{{1
""" stores dates for events """
eventdate_name = models.CharField(
_( u'Name' ), blank = False, null = False,
max_length = 80, help_text = _(
"Example: call for papers" ) )
eventdate_date = models.DateField( _( u'Date' ), blank = False,
null = False, db_index = True, validators = [validate_year] )
event = models.ForeignKey( Event, related_name = 'dates' )
objects = models.GeoManager()

The shell output is:
In [10]: event.dates.create(eventdate_name='start', 
eventdate_date=datetime.date.today())
Out[10]: 
In [11]: event.dates.all()
Out[11]: []

Why is event.dates.all() empty?

Does anyone have some advance?

Oh ok.

so it would be something like:

in home.html
{% include 'category-list.html' %}

in category-lists.html
{% load those_categories %}


?

Newbie: How to implement a app/module, which I can include from my html?

2014-11-27 Thread ThomasTheDjangoFan 
Hi guys,

I want to display a block of category-links in various places of the 
website. Those links are populated by making a Category.objects.all request 
in a view. So right now it seems like each view that should contain those 
links needs to put the "Category" Model in its context.

Now I would be really thankful for a tip on how to NOT repeat myself (DRY):
Is there a way to "{% include 'category-links.html' %}" and have the .html 
get its content from a specific view?

Kind regards
Thomas
