Apache environment variables in Django 1.6

[Jon Dufresne]

Hi,

I recently upgraded my Django application from 1.5 to 1.6. This
application runs on Apache with mod_wsgi. After upgrading, Django
seems unable to access environment variables set by Apache using
SetEnv and SetEnvIf. Using Django 1.5 I was able to access this using
the following recipe in wsgi.py:

---
import os

from django.core.wsgi import get_wsgi_application
_application = get_wsgi_application()

def application(environ, start_response):
os.environ['MY_SETTING'] = environ['MY_SETTING']
return _application(environ, start_response)
---

Then, in settings.py, I would access MY_SETTING using os.environ['MY_SETTING'].

Is this a bug that this no longer works in Django 1.6? Is there a
better way to access Apache environment variables?

Thanks

Model Design: Adding Params to Relationship FIelds

[Thomas Murphy]

Hi all,

I'm working on a hour-reporting system.

Each Project has many Users, and each User has many Projects(These are
established and working nicely).

My design issue is this:
How can I assign each User an IntegerField "Hours" on each Project
they are assigned to? This Integer Field is personal to them, but must
be able to summed by the Project "Hours" count later(This last part is
trivial to design, just wanted to include)

Here's relevant code:

class Project(models.Model):
client = models.CharField(max_length=500)
name = models.CharField(max_length=500)
campaign_start_date = models.DateField()
hours = models.IntegerField(default=0)
members = models.ManyToManyField(User)
hours = models.IntegerField(default=0)

def __unicode__(self):
return self.name

class UserProfile(models.Model):

user = models.OneToOneField(User)

#Additional Attributes Defined Below
project = models.ManyToManyField(Project)
rate = models.IntegerField(default=0)

def __unicode__(self):
return self.user.username

def project_names(self):
return ', '.join([p.name for p in self.project.all()])

Re: Using Aggregate and Count

[Timothy W. Cook]

Does the fact that I use a relat_name on the Review.paper field have
anything to do with it not working?

In the Review model, notice:
paper = models.ForeignKey(Paper, verbose_name=_('Paper'),
related_name="%(app_label)s_%(class)s_related+", null=False,
blank=False, help_text=_("Select a paper."))

In the annotation I tried:
papers =
Paper.objects.filter(project__id=self.kwargs['pk']).annotate(Count('papers_reviews_related+'))

with and without the '+'.   Still get a Field Error.

Thanks,
Tim

The django admin code is very extensible and re-usable. The
documentation may not stress this enough, but it is possible to do
virtually anything you want with it.

If I'm understanding your "outside" of the admin concept correctly,
what you want to do is extend the AdminSite[0] class (or maybe not
even that, just create a new instance) and attach the ModelAdmins you
want to it. I think you can even use autodiscover with a custom
AdminSite instance too if you need to have all models from
settings.INSTALLED_APPS attached to it.

Well, it should definitely work. Can you perhaps post your Review and Paper 
models?

I had actually tried this.  However, this is a reverse relationship
The foreignkey is on Review to Paper.  So if I use your suggestion or
even:
papers = 
Paper.objects.filter(project__id=self.kwargs['pk']).annotate(review_count=Count('review__paper'))

Which I first thought was correct.  I get a FieldError:
FieldError at /papers/papers_list/1
Cannot resolve keyword 'review' into field. Choices are: abstract, authors, ...

I thought that the docs at:
https://docs.djangoproject.com/en/1.6/topics/db/aggregation/#following-relationships-backwards

say this would work but apparently Django can't find the Review->Paper
relationship.

I'm stumped.

You're accessing a `review_count` attribute via each Paper instance, but 
you haven't set up anything that would do that - you only have a single 
top-level `review_count` dictionary.

Instead of a separate `aggregate` call, you should be using `annotate` on 
the original Paper queryset:

papers = 
Paper.objects.filter(project__id=self.kwargs['pk']).annotate(review_count=Count('review'))

Now each element in `papers` has a `review_count` attribute.

Using Aggregate and Count

[Timothy W. Cook]

I see there was a similar question on this issue earlier today but
alas it didn't answer my question.

In my app I have models for:
Project:  a project (not really part of this question but used for
context in the question).
Paper: an academic paper description
Review: a review of a paper
... other things not pertinent.

I can list Projects and from there I can list Papers assigned to each project.
In the listing of papers I want to show how many reviews there are for
each Paper.

Paper has a ForeignKey to Project and Review has a ForeignKey to Paper.

I have this code as my view:

class PapersListView(ListView):
model = Paper
template_name = 'papers/papers_list.html'

def get_context_data(self, **kwargs):
context = super(PapersListView, self).get_context_data(**kwargs)
papers = Paper.objects.filter(project__id=self.kwargs['pk'])
review_count = Review.objects.aggregate(review_count=Count('paper'))
print(review_count)
context['papers'] = papers
context['review_count'] = review_count
return context

and this in my template:

   


Title
Reviews
Year
Journal
Current Stage

{% for p in papers %}

{{p.title}}
{{p.review_count}}
{{p.year_published}}
{{p.journal}}
{{p.current_stage}}

   {% endfor %}



The print() inserted in the view gives me this:
{'review_count': 2}

In the rendered template the Reviews column is empty.

There are two Review instances in the database.  But, they are for two
separate Papers in two separate Projects.  So, my guess is that I have
two problems but after scouring the docs I can't determine where the
mistakes/misunderstandings are.

Any help is appreciated.

Cheers,
Tim

Re: Writing your first Django app, part 1

Found it.  I had Polls in the wrong place in the settings file.

Thanks!

Re: Writing your first Django app, part 1

[Jonathan Baker]

Is "polls" listed in within INSTALLED_APPS of settings.py? If so, does your
polls app have an __init__.py file?

Writing your first Django app, part 1

[Larry Barnett]

In the tutorial after I enter:

python manage.py sql polls

I get the following error:

CommandError: App with label polls could not be found. Are you sure your 
INSTALLED_APPS setting is correct?

I have built the site twice with the same results.  I cannot locate any 
error in the example or the Django environment. Everything worked prior to

works both adding or deleting a many to many related field so the 
difference is in the save methods
editform.save() in this working case and 
af = adviceform.save(commit=False)
af.organisation = organisation
af.save()
which doesn't

Now I deliberately used commit = False because I wanted to prepopulate the 
organisation rather than have the user select(again) the organisation so I 
therefore had to add the value of organisation to the form save hence using 
commit=False, unless someone can spot an error somewhere that is causing 
the problem or knows of a differnt way of accomplishing what commit does.  
Cannot just save the form as adviceform.save() because organisation MUST 
have a value see the Organisation model.
Any ideas?

Using admin views "outside" of admin

[Brad Smith]

Hello all,

Based on other threads I've read here, it seems that the conventional 
wisdom is that the admin interface is only for low-level access to the 
database, and isn't designed for anything "fancy", like users with 
different levels of administrative rights within an app, etc. Ok, I get 
that, but if I may grasp at some straws briefly I'd like to ask one 
follow-up that I haven't seen answered elsewhere: my app has a bunch of 
objects with complicated relationships for which I've devised a reasonably 
pretty and intuitive editing interface using Django's admin and Grappelli. 
Since this took a nontrivial amount of effort, I wanted to ask here if 
there are any tricks I should know about for re-using *any* views, inlines, 
etc from that admin interface in a more integrated editing interface with 
granular access controls, or do I just need to suck it up and rewrite 
everything from scratch using regular Django forms?

Thanks to anyone who can offer some advice. 
--Brad

Re: Django Admin Error: pop-up entry form

[Derek]

Solved.  You need to add "u" to the unicode representation of your model's 
record.  As in:

def __unicode__(self):
return u'%s' % self.fieldname

This "error" does not show up in the normal admin page for the model, only 
when its accessed via the pop-up route.

Re: Tango with Django Chapter 7 (Add_page)

[Amimo Benja]

Hi Lee,

I have been continuing with the django tutorials and at the moment I am on 
chapter 10 dealing with cookies.

On the exercises when a user logs in and clicks the about page link, mine 
just shows he visited the site 1 time no matter how many times he clicks on 
the about page. Is it supposed to be so or am I missing something?

Re: data not saving through a many to many relationship

[MikeKJ]

Decided that the relationship  advice = models.ManyToManyField(Advice, 
through='AdviceLevel') in the Organsiation model is redundant and removed 
it but it hasn;t made any difference to the now NON intermdiate model 
AdviceLevel

data not saving through a many to many relationship

[MikeKJ]

In the view do_advice the specialism, delivery_method and 
face_to_face_locations selections are not being saved into the 
corresponding tables
of 
advicelevel_specialism,
 
advicelevel_delivery_methodand
 
advicelevel_face_to_face_locationswhich
 are the fields of advicelevel_id  and x_id where x = specialism etc, 
normal many to many table right? 
The actual AdviceLevel table is properly saved to with the advice_id, 
organisation_id, the selected levels etc everytning that is not a many to

Non-Ascii Characters in URL causes crash

[Peter]

I have a slightly weird issue.  Someone is sending http requests with 
Chinese characters in the URL.  Ok, it's probably just Chinese hackers 
trying something.  But it's causing Django to fall over with a 
UnicodeEncodeError in the response.

I'm thinking this must be a bug in Django as the response is generated by 
Django itself.

I have flatpages turned on, and obviously this url doesn't match anything I 
have in flatpages so it's somewhere in the flatpage not found path.  I also 
have I18N turned on.

I'm running Django version 1.4.8.  Below is the traceback.

Should I just ignore this?

Are you trying to annotate each row in the 'articles' queryset with
the count of the number of publications associated with that article?

from django.db.models import Count
articles = Article.objects.all().annotate(num_publications=Count('publication'))

{% for article in articles %}
{{ article.id }}
{{ article.num_publications }}
{% endfor %}

Cheers

Tom

This is to be expected - in order to effectively test your code, you
need to write effective tests, which takes time.

The more tests you write, the better you will become at writing your
code in ways that make it easier to test.
