If using Apache/mod_wsgi it is quite simple, and wouldn't even need URL rewriting as suggested by others. So, what are you hosting it with.

Changing a constraint with live data
Hi everyone, Happy 2011. I am having an interesting problem where I need to change the foreign key on a model (A) to reference a different model. problem is, the table for A is populated with records and MySQL does not seem able to drop it. I ran manage.py sql and would like to drop the existing constraint and add the new one.

Problem with models
I have model of text, like that: class Text(models.Model): text = models.CharField() user = models.ForeignKey(User) #author And i need to compare two of texts, so i need table like this: class Compare(models.Model): text1 = models.ForeignKey(Text) text2 = models.ForeignKey(Text) user = models.ForeignKey(User) #who compared Now i want to get from Text table two random texts and at least one of them cant be compared yet by given user, how can i do this? if I try reverse relation compares_set, it doesnt work cause' i have two foreignkey of same model.

models queryset and permissions
Hi people, probably I'm making a mountain out of a molehill but I can't figure how to solve this problem; I've a form with a ModelMultipleChoiceField. The queryset will contains all models for which the user has a particular permission (django.contrib.auth.models.Permission) (can_add). This is the models.py class Esame(models.Model): name = models.CharField(max_length=80) name_model_referenced = models.CharField(max_length=80) class Ecg(models.Model): esame = models.ForeignKey(Esame) patient = models.ForeignKey(Patient, null=True) class Ecg_da_sforzo(models.Model): esame = models.ForeignKey(Esame) patient = models.ForeignKey(Patient, null=True) Supposing we have a user Tom which can add an Ecg but not an Ecg_da_sforzo, can I use the Django Queryset API to obtaing the correct queryset?

Serialize in django witha query set that contains defer
Hi, i have i little problem, and that is how can serialize a django
query with defer ?
I have this model :
class Evento(models.Model):
nome=models.CharField(max_length=100)
descricao=models.CharField(max_length=200,null=True)
data_inicio= models.DateTimeField()
data_fim= models.DateTimeField()
preco=models.DecimalField(max_digits=6,decimal_places=2)
consumiveis= models.CharField(max_length=5)
dress_code= models.CharField(max_length=6)
guest_list=models.CharField(max_length=15)
local = models.ForeignKey(Local)
user= models.ManyToManyField(User,null=True,blank=True)
def __unicode__(self):
return unicode('%s %s'%(self.nome,self.descricao))
my query is this :
eventos_totais =
Evento.objects.defer("user").filter(data_inicio__gte=default_inicio,
data_fim__lte=default_fim)
it works fine i think (how can i check if the query has realy defer
the field user ? ) but when i do:
json_serializer = serializers.get_serializer("json")()
eventos_totais = json_serializer.serialize(eventos_totais,
ensure_ascii=False,
use_natural_keys=True)
it always folow the natural keys for user and local, i need natural
keys for this query because of the fields local. But i do not need the
field user.

build application from admin code
Hello, I just started using Django and I am still "marvelling at all the code I didn't have to write". I wonder if this code, the admin interface, could be used for the application itself. I would like to do something like this: Each user of my application gets his very own predefined objects of a certain kind, which he can use, change, delete, and so on. He gets his own urls and views that are but modifications of the automatically generated admin urls and views. Like so: example.org/juan/grammar/verbs/add/ (a modification of example.org/admin/grammar/verbs/add/) or so: example.org/merche/recipes/delete (a modification of example.org/admin/recipes/delete) Juan and Merche are users of example.org, but they can have and administrate their own users. Juan, e.g., might have the users Maria and EmacsGuru. Maria and EmacsGuru can only view and manipulate the pages that Juan allows them to. And Juan can only view and manipulate the pages that the admin of example.org allows him to. Has anyone done something of this kind? Is there example code?

admin.autodiscover()
urlpatterns = patterns('',

Could this problem be related to windows 7 environment variables not
being set properly? I ask because I was upgraded recently from Win XP
to Windows 7 and have been working to set up my environment variables

them, but maybe I missed something. Please advise. Thanks.

Re: Changing a constraint with live data
You could do this with South in multiple steps. 1. South schema migration: Add the new field for the proper foreign key, but don't make the field required. 2. South data migration: Create a migration that appropriately populates the new field based on whatever rules you have. 3. South schema migration: Make the new field required, and optionally delete the old field. Shawn -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: build application from admin code
Now that you're luxuriating in the "done for you" aspect of Django, check out the ModelForm object. It gives you the goodness you seek. I don't think that setting up your URL system the way you describe is a good idea. It's a complete security failure, so you'd have to handle permissions anyway. Therefore, there's no benefit to having the username as part of the URL.

Re: Syntax Error
Is it possible that the problem is not in this urls.py, but rather in
'polls.urls'?
I'd check line 20 there, just to see if there's an obvious python
syntax error.

form handling in views.py
Maybe smbd could give advice how data submitted from custom.html to
views.py are handled further?
custom.html with method search1 ##
{% if Lp %}
{% for item in Lp %}
{{item.Word}}
{{item.dateWord}}
{% endfor %}
{% endif %}
views.py with method search1 ##
def search1(request):
request.encoding='utf-8'
query = request.GET.get( 'q','')
The code above works when i have one button and one text area.
I do not understand
how to find out which input was selected and
how to read text from many text areas (how to relate several text
areas in row with single button in that row ) .
regards,
gintare

Re: Syntax Error
OK. There were some problems with my django installation, due to the
OS upgrade on my machine, and things which were missing in at least
one environment variable. Since correcting these problems the basic
functionality of my tutorial site appears to be working again. Now I
appear to have at least one problem in my views.py file. Thanks for
the suggestion. It did helpme find the problem(s).

Custom queryset on a ModelForm field
Hi,
I have a 'project' model
class Project(models.Model):
title = models.CharField(max_length=100)
links = models.ManyToManyField('Link', related_name='link')
and a 'link' model
class Link(models.Model):
label = models.CharField(max_length=50)
url = models.URLField(max_length=100)
project = models.ForeignKey(Project)
I want the user to edit his project properties. I'm using ModelForm class
and a UpdateView to put everything together. But I have a problems:
I want the form to only show those *link*s who are owned by the project in
the MultipleChoisesWidget, hence the ForeignKey in the Link model.
Any help on how to achieve this? Thanks!
P.S why isn't there a proper API documentation on django like doxygen? I
find the django documentation full of content but awful structure!

Don't do any of that. Instead, read the excellent documentation about the

What actual project name are you using? Have you tried using different project names? If you're literally using "projectname" then you may be using a command-line argument and causing a conflict.

The screen will have a dropdown box, a conditional textbox, and a submit button, as well as some other informational fields and a title on it. Since this is my first explicit attempt at using a form I have the following questions: 1. How does my form get recognized by or associated with the html screen file? 2. What form field type do I use to pass a list/collection in the form to the screen (Once I get it there I know I can display its individual items from within a for loop)? 3. Then once the user selects a value from the dropdown box, how can I read the value selected, in my view? 4. Finally how do I conditionally display the textbox only if the user has selected a value from the dropdown box and not display it if a value was not selected? I would appreciate any help with any or all of the above questions. Sorry if they're too simple, but I'm a newbie and almost everything about django is new and not necessarily intuitive to me just yet. Thanks. -- You received this message because you are subscribed to the Google Groups "Django users" group. To post to this group, send email to django-us...@googlegroups.com.

Via the view, just as with any other type of content. See the documentation
on Using a form in a view:
http://docs.djangoproject.com/en/1.2/topics/forms/#using-a-form-in-a-view

forms.ChoiceField or forms.ModelChoiceField. And you don't need to use a for
loop, just render the field via {{ form.myfield }}.

By instantiating the form with the values from request.POST. Again, the
forms documentation explains all this in 'using a form in a view'.

You'll need to do this in Javascript.

automated testing: how to generate human-verifiable views?
Hi, I'm trying to figure out the best way of doing something I'd like to partially automate staging testing by generating a sequence of human verifiable views, with the goal of making sure my app views/css/ 3rd-party javascript etc. are drawing the way they ought to in more complicated scenarios.While back end code can easily be tested with TestClient, failures in the 'final mile' of rendering are really annoying. It would be nice to have a 'view test mode' that allows a tester to click through a series of database configuration / URL pairs in a relatively painless way. Is there a standard way of doing this, or any existing modules I could use to achieve this? Jennifer -- You received this message because you are subscribed to the Google Groups "Django users" group.

A few beginner questions
Hello, I am experienced PHP developer (and by PHP I mean advanced programming with MVC frameworks, TDD, ORM libraries, design patterns and such, so no scoffing please :)) and I would like to try something new. I've chosen Python and Django and I am building my bachelor thesis project with it. I dived directly into django-nonrel fork, because I am building the project on App Engine. However, I have few basic questions that concern basic relational Django as well. 1) Since Python has no object encapsulation, I have no idea how to implement computed columns in its models. E. g. I want to save forum post rating in the "posts" table even if I have related table with all the related post votes because it's faster and no joins are required to get the rating value. 2) I would like to perform some integrity checking before saving object to the database. I found here (http://docs.djangoproject.com/en/ 1.2/topics/db/models/#overriding-predefined-model-methods) that I can override entity save method and stop it's execution before calling parent implementation. However, this didn't work for me for two reasons - it somehow caused 500 error on App Engine (because the app does not know that the object was not saved?) and it does not meet my needs - I would like to "attach" some error message to this application state and I would like this message to bubble up to the form errors (in case it happens when a form is submitted) in a way compatible with Django admin, so the user can fix the problem. 3) I would like to read about some best practices about midsize and large Django projects. How to organize the code, what directory structure to choose etc. Are there any additional layers between model and views widely used? Where should I put my code that is not directly related to model and is used in more than one view? Can you recommend me some articles about this topic? 4) What about dependency injection? From what I saw so far it seems like Django is full of singletons, static attributes and methods and hidden dependencies, which are considered as bad practice. For example how can I use two connections to two different databases to load and save model entities? Are there any "inversion of control" concepts? Thank you very much! And you can expect more questions to come in this thread :) Ondřej Mirtes from Prague, Czech Republic -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: automated testing: how to generate human-verifiable views?
Can you elaborate a bit? Are you interested in having the ui render and generate a screen shot for human review? That's how I interpreted your question. If that's the case, look in to generating a screenshot by leveraging a tool that generates a png from HTML. I am eager to hear what others think.

Re: automated testing: how to generate human-verifiable views?
OK, to elaborate: I have a open source project with consistent pain points around css and browser testing. Example concrete issues for this project are a) multi-language support, as varying text length will often throw off the aesthetics of the layout, and b) recently, a mysterious failure in geodjango google-map drawing where in some corner-cases, the map silently fails to draw. Really, I'm looking for a framework for a human tester to be able to look at a sequence of html pages generated with different test data in the database. I want the tester to be able make a 'pretty/ugly/ horribly wrong' call without having to do a bunch of clicking or data entry. Ideally, they would just click 'next' on some widget, which would pull up the next URL/test db combination.

You're problem here suggests two things to me, 1. you're a novice to python/django (it's fair, we all got to start somewhere). 2. you have no clue on how any of your operating systems really work (again we have to start somewhere). I would suggest before you run off and make "the next big website", you sit back and take a few weeks to learn the basics of both administration for your operating systems (focusing on what os your site is going to run on in production) and working with python before you start building your site. (if this is a problem, i.e. you've taken a job without the minimum requirements met and need to get this done now, then do them side by side). If you don't, you'll find yourself with many more headaches like file permissions, where files are uploaded and how to access them and store them securly, dealing with module paths and import problems and even figuring out how to get your webserver of choice to serve your django site. These are mainly operating system issues. Also learn the difference between a python module and a python application. In this case django is a python module that provides a few python applications to make the developers life easier. You should be able to recognize them on sight and be able to use them both easily before you begin developing. Also if you google your error and the command name[3] you'll see that the solution for you in the first page of results (in this case the first hit[4]). 99% of most problems are answerable this way... as others have documented or asked a similar question and given a solution from various sources. If your google-fu isn't that great, time to practice this also. It'll save you much time and headaches. For me, these three things are essential: Knowing how a computer works, knowing how your operating system works and knowing how a programming language and the tools work are 3 different things and equally important in development, regardless if it's a website, desktop application, or server/service. IMO a good developer is also a good admin and visa-versa. *being an admin led me to being a developer, from wanting to understand how to debug and trace application issues to get around problems* Mike [1] http://www.tech-recipes.com/rx/2621/os_x_change_path_environment_variable/ [2] http://code.djangoproject.com/browser/django/trunk/django/bin [3] http://www.google.com/search?q=command+not+found+%2Bdjango-admin.py [4] http://code.djangoproject.com/wiki/InstallationPitfalls -- The worst cliques are those which consist of one man. -- G.B.

Re: A few beginner questions
Hi Ondřej. For your question #1, you could create a field in the model itself and then use signals[1] to populate it upon the saving of a "vote" instance. #2: The validation should all be done during form validation[2], prior to save. Using a Form or ModelForm. That way, the user can get friendly, useful errors. #3: I have no idea. Maybe someone else has recommendations. #4: There's a whole lot of stuff in that question. Maybe if you broke out some specific examples someone will try to explain the rationale behind the design.

The most likely reason for no user attribute on the request at this point is missing AuthenticationMiddleware, but if AuthenticationMiddleware is in place then there must be something else causing the problem. I happened to just stumble across one of these other possible problems: some other error in the project code. In my case I had a model with a method with a @Property decorator applied (leftover deliberate error to see what message that would generate -- should be @property). With that error in place, adding RemoteUserMiddleware to my config and trying to access the site via apache/mod_wsgi produced the error message you are seeing. The real error was obvious when I tried running the dev server, which would not even start properly with that error in place. Also, removing the RemoteUserMiddleware from the settings and accessing the site via apache/mod_wsgi showed the true error. Once I removed the erroneous @Property decorator, the RemoteUserMiddleware error went away. I'm not sure why this RemoteUserMiddleware error is having the effect of hiding other errors, and don't have time to dig into that right now. But one possible way to figure out what is going on in your case would be to try removing that middleware and seeing if some other error is reported.

Any Django framework command to freeze/wait/notify ?
Hi all, This is a common scenario which many of you have faced. Say, I created a simple view file, in which user uploads a file and does some processing at backend and after processing is finished I am rendering a html page with some processed result. My problem is that, there should be some kind of a mechanism, by which I can notify user that "processing is going in background, so please wait till the processing finished." So, what are the easy to implement options I have ? Does Django provides something for these scenario ? Will javascript (timer mechanism) work ?
