Getting into professional django development
Hello everyone! I have been using Django for about a year now and feel that I want to take my experience to the next level. I have created a few website using Django to test my skills, although not for anyone specific. I am creating this thread as I will like to ask current Django website developers what tools and apps are crucial to be learned. Currently I have been focusing on the following: * Django 1.2 * Django-guardian * JQuery(although not specific to django) * Pyjamas(nice alternative to GWT and works with django) * Began learning Pinax(based on Django 1.1) * Began learning Django-cms * A few other, but cannot remember off the top of my head. The problem is that I'm not really sure what Django apps to learn due to the overwhelming amount of apps that do the same thing, just differently. I choose Django-guardian over Django-authority, for example. The next django app I plan on learning is Djax and Djaxice. Which Django apps does everyone use in their Django projects for your company/clients? I'd rather not learn something which is either going out of style, out of style, out dated, or barely used. I cannot take this type of experience with me to work on a larger scale project. You must agree that when you look at the djangopackages website, there are an overwhelming amount of apps which do almost the exact same thing. I'm not sure how it feels the download counts, or the other data. I would hope from PIP, but not sure if it has an open API for polling download counts and such data about packages. -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Blank output from treemenus under nginx
This is rather common when moving over from the dev server to a
production environment. Sometimes it can be tricky to map all the
static URL paths in the web server serving the static content, such as
the JavaScripts which treemenus uses. I haven't used treemenus
before, but from past experiences with working with different apps and
moving over to a production environment, I can advise the following
steps to troubleshoot.
* Compare the output HTML from both the dev server and the production
server.
* Make sure all the resources pointed to by the production server
exist, eg. /media/js/mycode.js, in Firefox you can click these
resources in the source view.
* If any resources return a Django error, or a 404 page, that's where
your problem lies. You will need to create a few location {} blocks
in nginx to point to the resources on the production server. You
should have already done this for the admin app.
* Make sure you have everything needed installed on the production
server, although if anything was missing Django would have gave an
ImportError exception, it's still good to check.
* Be sure that nginx is passing all the header information to the
application, I'm not sure how wsgi works, I personally use FastCGI
with Django and Nginx.
* Check the nginx log files to see if there are any 404 or 500 error
messages, the page won't display these for resources such as a missing
JS/CSS file.
Hope this helps in your troubleshooting efforts.

Re: Ajax replacement in django
Just a simple thought, if you'd prefer to avoid JavaScript/client-side scripting entirely, and only code using Python. It might be an idea to look at Pyjamas to generate your page. It technically uses Ajax, but from the programmers point of view, it feels more like coding a desktop application. The exposed functions on the django server are mapped as Python functions in pyjamas, so coding Ajax in this method seems very natural for a python programmer. Depending on what type of web application you are attempting to build, this might be a good solution for you. The tools you use all come down to what the end result should be. Is it a website or a web application? Should the look and feel be more like a desktop app, or a newspaper? Pyjamas also strives for cross-platform/browser compatibility for a true code once, run anywhere feeling without the Java. Pyjamas also supports some HTML5 features such as the canvas to further a desktop app like feeling for the end user. One can also mix traditional HTML and a Pyjamas app onto a single page. If, for example, your project requires a small widget which updates from the server constantly(news feed/chatbox), you can make the entire site using standard HTML/CSS and embed a Pyjamas app into a DIV tag on the site. Hopefully this gives you some ideas.

"Before the form is even displayed" is a bit of an ambiguous statement. The form isn't displayed until it's rendered on the client's web browser, and the rendering doesn't happen until the very last action in a view, so putting your logic *anywhere* would result in it being executed "before the form is displayed". The form is *constructed* much earlier (in, unsurprisingly, the get_form() method). However, the "right place" for your business logic will very much depend on what behavior you're trying to add. The easiest way to thing about this is probably to think about the problem in terms of what the Class Based View is replacing. The internals of a CBV is essentially just an implementation of the following: def my_view(request): if request.method == 'POST': form_class = get_form_class() form = get_form(form_class, data=request.POST) if form.is_valid(): return form_valid() else: return form_invalid() else: form_class = get_form_class() form = get_form(form_class) return render_to_response(context_data()) If you can find the appropriate place in a function-based view, just find the analogous place in a CBV.

Blank output from treemenus under nginx
Hi everyone, I got a surprise when using treemenus, where it worked really well on my local dev (django-server) , but disappeared on live (nginx using mod_wsgi on debian). I installed the treemenu app, imported the data (menu items) from a datadump of my local app, and uploaded the templates that use treemenu. No error, but no output either. When I went to the Admin, the menus were there, but editing the items resulted in a blank editing area. I switched on debug briefly on live (in maintenance mode), but no error was reported. Has anyone else experienced blank output under mod_wsgi but not local dev? If not, could someone suggest where I could start debugging? Usually I check logs for errors or use the django error page, but both are blank :-( I've had to hard-code the navigation across the site in the meantime, which is going to get time consuming very quickly!

Re: Tutorial confusion: flat project layout with django 1.3.1
Actually, it seems like the search popup should focus on whatever documentation you're looking at. So, instead of saying "Django 1.3" I would argue that it should have said "Django Dev". That would mean that it was defaulting to the use it would probably be put to, and simultaneously tell the reader which version of the docs he's looking at. -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Tutorial confusion: flat project layout with django 1.3.1
Ah! Thanks everyone for the feedback. The reason I was confused may be stupid, but FWIW here it is: Underneath the Search input area, there's a popup menu that says "Django 1.3". My eye went over there and registered the 1.3 without figuring out that it refers to what is being searched in. I recall the thought crossing my mind that if I went to a different item on the popup, it would take me to the equivalent docs for a different version. I see that you do have functionality like that -- it's just that it's in the bottom right rather than the top right. I'm not saying I didn't make a dumb mistake. Fact is, I didn't notice the "Documentation version" widget in the bottom right. I'm quite rushed right now, and don't spend a lot of time looking at the django docs, and did not absorb the fact that the popup that said "Django 1.3" is between the text input area for the search and the search button itself -- I just glanced over, and saw the version number. If the text to the left of the popup said "Search in version" rather than just "Version" the probability that I would have avoided the mistake would have been increased, but I'm not sure how much. If the popup text itself was "Search Django 1.3" rather than just "Django 1.3" I am pretty sure I wouldn't have made the mistake. -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Question on cleaning ModelForms
I've done it before using a post save signal, although I had lat,lng = NULL
in the schema so that differs from your request here. After saving, I would
issue an update. I forget why I didn't use a pre-save signal.
Aside from signals, you may also be able to use a model field default with a
callable to set the lat/lng of the FarmersMarket object. It's an idea I
haven't tested, so I'm not positive it will work.
You could write some geocoding middleware that sets request.POST data in
some way as it passes through. I don't really like this solution since it
is kind of "magical."

django 1.3: how to use pagination with class based views?
Hello, I have following view in views.py: . class ArticleArchiveIndexView(ArticleViewAbstractClass, ArchiveIndexView): queryset = Article.live.all() date_field = 'pub_date' context_object_name = 'articles_list' paginate_by = ARTICLES_PER_PAGE .. How do I use 'paginate_by'? Should the Article model have Paginator instance? Please provide an example with template.

Question on cleaning ModelForms
class FarmersMarket(ModelForm):
class Meta:
model = models.FarmersMarket
exclude = ('location',)
def clean(self):
place, (lat, lng) = _g.geocode(self.cleaned_data['address'])
self.cleaned_data['location'] = Point(lng,lat)
return self.cleaned_data
Here's my code minus the exception handling. Now what I *want* to
have happen is that the models.FarmersMarket.location field on the
model is set sometime shortly after the form is submitted by the user,
by way of geocoding the data, rather than having them tediously enter
a POINT wkt string in the textarea field. So my idea was to put a
call to geopy.Google.geocode in FarmersMarket.self.clean. I can
confirm clean() is getting called, but for some reason, the 'location'
field isn't being set in the model. I get a whine from Django that
the location field cannot be NULL (which is true, it can't).
Can anyone tell me how I'm supposed to be doing this? I want them to
enter an address on the form, not a latitude/longitude pair.

Re: Iteration over queryset in a model
Ok, sorry I thought I was starting to understand it a little better,
but now I think I took a step backwards, so if it is ok with you let's
step back and take it a step at a time.
So, my first step is wondering if I really need a manager or not??
I was thinking from your first response to me that you might be
suggesting that I did. Let's start there.
If I understand it correctly the Manager is a way of retrieving
specific information.
thanks

cannot concatenate 'str' and 'FilterExpression' objects
Dear Folks,
I am using a number of subdomains for my website and decided to create
a custom url tag and try as shown on
http://stackoverflow.com/questions/3461806/django-subdomains-and-mod-rewrite-urls-messing-up-on-deployment-setups
My template tag being used in my template like this:
About
Us
My template tags functions looks like this:
class SubdomainURLNode(URLNode):
def render(self, context):
request = context['request']
domain = request.get_host()
subdomain = re.sub(r'^www\.','',domain).split('.')[0]
path = super(SubdomainURLNode, self).render(context)
return "%s/%s" % (str(request.get_host()), path)
@register.tag
def subdomainurl(parser, token, node_cls=SubdomainURLNode):
"""Just like {% url %} but checks for a subdomain."""
node_instance = url(parser, token)
return node_cls(view_name=node_instance.view_name,
args=node_instance.args,
kwargs=node_instance.kwargs,
asvar=node_instance.asvar)
While trying to render the template tag it comes back saying:
TemplateSyntaxError at /
Caught TypeError while rendering: cannot concatenate 'str' and
'FilterExpression' objects
My template tag function does not return the path value from the
statement:
path = super(SubdomainURLNode, self).render(context)
because the URLNode function fails on line 442 because of a type
mismatch:
url = reverse(project_name + '.' + view_name,
I just tried using the standard url method in django {% url
"app.views.view_decider" "about" %} and this works. I would like to
know where I am going wrong with my function so I can get this to
work.
The full traceback of the error is below:
Thanks in advance.

Looking for a good Document Management System (DMS) to plug into my Django app
Hi folks, I have been looking around all over to find a high quality DMS to plug into my Django application. I'd like to be able to upload and download .docx or .pdf files, edit the metadata, and also be able to serve the content of the files on the front end. If the plugin allows for preview, that would be great as well. I am currently building a content rich django app and need to be able to do something like this: http://bit.ly/pUyLyC I have come across Mayan, and although it has all the features I need, its a separate app in itself and there is no API for me to connect my app to data sitting on Mayan. Any other insight or points in the right direction would be tremendously helpful. Best, Harshil -- You received this message because you are subscribed to the Google Groups "Django users" group.

Hey, I have a FormView and a Form. I want to put in some logic that will take place before the Form is even displayed.

Re: Automaticall list all fields of generic model in template
Did either of you read the OPs email? He is not looking for forms... OP: There is nothing built in, but you can easily iterate through a model's fields, they are all available in the _meta attribute on a model instance: >>> u = User.objects.get(id=1) >>> for field in u._meta.fields: ... print "%s => %s" % (field.name, getattr(u, field.name)) ... id => 1 username => tevans@... first_name => Tom last_name => Evans email => tevans@... is_staff => True is_active => True is_superuser => True last_login => 2011-10-17 15:46:33 date_joined => 2008-11-10 10:54:33 Using this information, you can easily produce a method that will output a HTML table of that data. If you can modify your model classes, you can make them inherit from an abstract base model that includes this method, and then it will be available in all your classes (that inherit from the base class, obviously). Much more hackily, you could monkey patch models.Model instead.

Re: models.Model
Hello Daniel thanks for your answer and sorry for my english. As you said, it could be a problem of translation !!! :-) I really appreciate your help, I'm doing lots of progress in my python object programming curve ... OK, then to be sure how Python works ... let see this code: 1 from django.db import models 2 3 class Person(models.Model): 4 first_name = models.CharField(max_length=30) 5 last_name = models.CharField(max_length=30) Ligne 1 imports module "models". I've browse the source code of Django. In the "models" folder, there is a __init__.py file and a lots of .py other files. There is folders too and specially one called "fields". Here is my question : - When importing models on line 1, doest it import all the .py files in this module, then all classes, Class, functions, variables at the top level of each .py are available for use ? Or there is only an automatic import of the __init__.py ? Line 4 : : The CharField Class definition is in models/fields/__init__.py. In the code above, there nowhere a reference at "fields". But the line 10 of the the __init__.py in models is " This file is automatically loaded by Python. In this file on line 10, there is "from django.db.models.fields import *". " Here is my question : - Does it means that the CharField Class is available inside Person Class because there is a cascading import following this way: - models contains an __init__.py wich import fields and __init.py in fields has a definition of Class CharField on line 601 Hope it's enugh clear ... don't spend much time when it is not and just ask for reformulation, I'll dot it ...

The order of configuration in the file is also important; on a connection attempt the records are examined sequentially.

Re: Tutorial help: Make the poll app modifiable in the admin
thanks for your reply. 1. yes i am following the tutorial explicitly. 2. yes, i haven't removed it. 3. yes using 1.3 I did manage to find a workaround though. I simply executed the commands via the python shell (run-> shell). the error i was getting was when i went to run->run module.

Re: Django models design question
Hello Omer -- I believe you have two options. You could use the AttributeValue approach I described earlier. You could add features to take care of 'data types' and the like. The work may be quite tedious, but it has the advantage of not being clever. In other words, you would do the work to implement each feature as you like, with no magic involved. The other approach is to extend django/python itself. Basically the approach here is what has been called dynamic models. You can google for it, but your best bet is probably this blog post and the pages it references. http://martyalchin.com/2007/aug/14/dynamic-models-in-real-world/ However, note that the article is over four years old. You would no doubt have to update this approach for django 1.3. This approach would require knowledge of django/python extension points and likely some internals. It's probably the "better" approach assuming you are up for it. You would have to decide when to construct these dynamic models, among many other decisions. I'm on holiday for the next couple days, but I will check back with the list to see how you're getting on when I return.

I didn't say that a function can't be imported. It definitely can. As you
say, function and method aren't the same thing - a method is a function that
belongs to a class. It's not possible to import just a method, because
there's no way of referring to it except via the class. But anything at the
base level of a module - whether it's a class, a function, a variable,
anything - *can* be imported.

Person inherits from models.Model, so all methods that are defined in the superclass are also available to the subclass - that's how Person gets methods such as `save`. As for `max_length=30`, when you instantiate a class Python calls the `__init__` method of that class, which in this case accepts a number of arguments including max_length. -- DR. -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: models.Model
hello again, sorry for eventually annoying. But later in the Django
tutorial,
there is this code:
from django.conf.urls import patterns, include, url
.
urlpatterns = patterns('',
(r'^polls/$', 'polls.views.index'),
..)),
)
What I understand here is that "patterns", "include" and "url" modules
are imported.
After the result of the function "patterns" is assigned to
"urlpatterns". AS Daniel said that a function can't be imported, this
means that a method can be called (but not imported) or this means
that a function and a method are not the same thing ?

Re: models.Model
Thanks you 2 for your answers. I think I've understood now. Again I apologize for the newby Python question but I've read three times "Dive in Python" and it hasn't made me thnigs clear. That's the reason why I've posted. I thought there was a hierarchy like this models.Model.CharField That's the reason why I didn't understood. Daniel, you said, that a method can be imported, this mean that an external method (method from a class like Model) can't be used directly in the Person class for example ? If I understand well, in "first_name = models.CharField(max_length=30)", first_name is an instance of class CharField. This instance send "30" to the "max_length" parameter of class CharField. This parameter is used by an internal method of class CharFiled.

You need to set your pg_hba.conf settings to allow the user to connect. The default config on Debian/Ubuntu is to allow you to connect to Postgres as the same username as the OS user.

At the root of your confusion, I think, is that you're mixing up methods and modules. `models` in the code above is a module[*] containing multiple classes. You can't import a method, as that's simply a function belonging to a class. You can import modules - `from django.db import models` - or elements such as classes and constants directly inside a module - `from django.db.models import Model`. So, the `models` module includes a class named Model, and also several other classes which represent fields - CharField, BooleanField, etc. All of these live directly inside the models namespace, so are referred to in exactly the same way - models.Model, models.CharField, etc. -- DR.
