You can supply your own form that is using customized widgets to
construct the fields with.

I don't know if this is your problem, but in order to use certain file
formats in PIL you have to have some prequisites installed. Here is
the PIL doc page for PNG support:

http://www.pythonware.com/library/pil/handbook/format-png.htm

In particular, note:

"PIL identifies, reads, and writes PNG files containing "1", "L", "P",
"RGB", or "RGBA" data. Interlaced files are currently not supported."

And also:

"Note: To enable PNG support, you need to build and install the ZLIB
compression library before building the Python Imaging Library. See
the distribution README for details."

You do it by supplying your own widget to the form field. See:

Hmmm, I don't see anything obviously wrong. I just did something like
this myself with a model form and it worked fine for me.

What version of Django are you using? And sorry to have to ask this,
but are you using the development server? (Just ruling out that the
code is getting reloaded after you make changes.)

Well it looks like you are trying to hide the field "name". So why are
you showing us the HTML for the field named "last"?

I just did this the other day and it worked for me.

Ok, then why are you storing date and time together when all you care
about is time? To me, when you have a DateTimeField, that represents a
point in time. It doesn't make a lot of sense to ask: "does this point
in time occur less than 14:00 hours." 14:00 hours on what day? Today?
Yesterday? That is the source of friction for me. Maybe you could
explain your model a bit more.

Maybe you should consider using a TimeField instead, then your query
would be more natural.

But if you really do need to store dates and times together, then yes,
I don't think there is an easy way to just query on the time part of
the DateTime field. You might look into the new F() syntax, but you
might just have to write your own SQL.

Well, the model field is storing a date and a time. So you can't just
compare that against a time, I don't think. You need to pick a day and
a time. And then you can do the filtering, you've almost got the
syntax right. Something like this should work:

MyModel.objects.filter(date_field__time__lt=datetime.datetime.(yy, mm,
dd, 14, 0))

Assuming date_time is a field on your model:

results = queryset.filter(date_time__gte=datetime.datetime.now())

See the docs on field lookups:
http://docs.djangoproject.com/en/dev/topics/db/queries/#field-lookups

Also, you want to construct a datetime object that is equal to now,
not compare your field to the datetime.datetime.now function.

Probably what is happening is that some of the other fields you are
excluding are required fields. Thus you should use the ModelForm save
with commit=False, then assign values to the rest of the fields, then
do a save on the object.

new_member = form.save(commit=False)
new_member.x = something
new_member.y = something_else
...
new_member.save()

Where x and y are the other required fields.

I seem to recall that when you put references to files in your CSS,
they are relative to that CSS file, not to the document root. So if
that graphic file is in the same directory as your CSS file, change
your url to:

background: url(header_background.gif) no-repeat top left;

Models are simply models. They don't really say much about forms. What
the admin application does is to make some default choices about how
to display your model in the admin interface. It automatically builds
the form to edit your model using some very reasonable defaults. If
you aren't happy with those choices, you can provide the form that the
admin should use instead of the default one. In your form, you are
free to use different widgets for your fields and/or provide custom
behavior.

The docs describe how to provide your own form to the admin here:
http://docs.djangoproject.com/en/dev/ref/contrib/admin/#form

You simply provide an attribute on your ModelAdmin called 'form', set
equal to the form class you want the admin to use. This form class
should inherit from ModelForm. You can then customize the widgets and
behavior anyway you would like.

ModelForms are discussed here:
http://docs.djangoproject.com/en/dev/topics/forms/modelforms/#topics-forms-modelforms

Overriding the default field type for a field on a ModelForm is a bit
further down:
http://docs.djangoproject.com/en/dev/topics/forms/modelforms/#overriding-the-default-field-types

But before you read all that, make sure you understand forms in
Django, in general:
http://docs.djangoproject.com/en/dev/topics/forms/#topics-forms-index

Armed with that info, you should be able to make a custom form for the
admin to use. Good luck.

I thought you were trying to make a form. Are you trying to do all
this from the admin?
If that is the case you can provide your own form that the admin will
use. In that form is where you specify the fields and widgets you
need.
Take a look at the forms documentation and also the model-forms docs.

There is a form widget called SelectMultiple:

http://docs.djangoproject.com/en/dev/ref/forms/widgets/#django.forms.SelectMultiple

You could use a ChoiceField with a SelectMultipleWidget, it would
seem.

I don't think so. request.user gets set by Django based on cookies, so
it should be trustworthy as request.user.username.

It would help if you posted your model.

But from what you posted, I'm guessing that line needs to read:

obj.user = User.objects.get(username=request.user)

or maybe just

obj.user = request.user

Forms don't work that way. They aren't used to display arbitrary data.
They are used to display form fields. It sounds like you don't want
the username as a form field, you just want it as normal text. You
need to pass non-form field data to the template, in the context
dictionary. Forms should be constructed with data to bind to the form
fields (such as request.POST data) or maybe initial values for the
form fields [1]. Please see:

http://docs.djangoproject.com/en/dev/topics/forms/#using-a-form-in-a-view

and especially:

http://docs.djangoproject.com/en/dev/ref/forms/api/#ref-forms-api

So you'll need something like this (for the non-POST case):

form = MyForm()
username = ...
return render_to_response(template_name,
   { 'form': form,
 'username': username,
   },
   context_instance=context)

And then in your template, this should get you started:

{{ username }}
{{ form.as_p }}

but realize there are many other ways to display a form as the docs
note.

Hope that helps,
BN

Django and Python Warnings

[Brian Neal]

I updated my working copy of Django after a long period and was
browsing the source and noticed it was taking advantage of the Python
warnings module. What is the best way to "see" such warnings when
doing development? Is it possible to configure Python or the Django
development server to display such warning messages?

For example, I was still using admin.site.root instead of include
(admin.site.urls) in my URLConf. I see the new code now issues a
PendingDeprecationWarning for this usage, however I didn't see it in
my development server window. I'm guessing I need to turn these on
somehow?

Thanks.

Well after some thorough review of the Admin docs and some googling, I
think I found my problem. My current urlpatterns looks like this:

urlpatterns = patterns('',
   (r'^admin/(.*)', admin.site.root),
   ...

I think the new way is to do this:

urlpatterns = patterns('',
('^admin/', include(admin.site.urls)),
...

I haven't confirmed this yet but I think this will get my custom admin
view registered correctly now after skimming the django code.

I put an assert in my get_urls() function and it was not getting hit.
I made sure that my Django contrib/admin/options.py file does indeed
have the get_urls() function.
I deleted all the *.pyc files under site-packages/django and redid the
'sudo python setup.py install' step.
Still no go. I think it is just trying the last default pattern in the
base ModelAdmin get_urls() and choking on that.

ModelAdmin get_urls w/ invalid literal for int() with base 10

[Brian Neal]

I'd like to make my own custom view. In the past I did this by
following the django book and added a URL to my main urlpatterns above
the '^admin/(.*)' pattern. But I noticed a new get_urls function on
the ModelAdmin class in the docs. I'm on trunk, and just did an svn
update to 9975 to try this out.

The docs for get_urls show the view being registered as self.view. Is
that possible to register a class method as a view?

Anyway, just to try things out, I created a view function right in my
admin.py file, and my admin.py file looks like this:

http://dpaste.com/6643/

I'm kind of guessing here about the URL I need to visit to trigger
this new view. My model lives at admin/gcalendar/event, so I'm
guessing I need to visit admin/gcalendar/event/my_view. When I do
that, I get this error:

ValueError at /admin/gcalendar/event/my_view/

invalid literal for int() with base 10: 'my_view'

With this traceback:  http://dpaste.com/6649/

For reference, here is my models.py:  http://dpaste.com/6650/

I did start to use lxml.html.clean on my project. I tested it (very
casually) and it seemed to work just fine. However, in one spot in my
code I needed finer control over what tags to allow. According to the
docs and the options, it looked to me like you could operate it with a
white list. However this didn't work out in practice. The options you
give to the cleaner are confusing and seem to contradict each other. I
couldn't get it to do what I wanted. I asked about this on the mailing
list and it was conceeded that the options didn't work together very
well. I also studied the source code a bit and came to the same
conclusion.

I then turned to using Markdown and recalibrated my opinion on what to
allow as input from the user.

Thanks for the link to html5lib though. I will keep that in my back
pocket.

Interesting, I've also come across this:

http://codespeak.net/lxml/lxmlhtml.html#cleaning-up-html

I've heard it is very fast as it is just a python binding to a C-

I've been using Markdown after seeing it used in many places. There is
a safe mode that instructs it to escape the HTML it would normally
allow. Check the django source for usage.

I'd like to hear more about this as well. The Django docs don't say
much about this, but the Django Book still has a section on this that
is still relevant to 1.0. See http://www.djangobook.com/en/1.0/chapter17/
and scroll down to the section titled "Creating Custom Admin Views". I
used the advice in there to create a custom admin view that allowed a
site admin to send a bulk email to all people registered with the site
email list.

I'm not quite sure if this is what you are asking about, but look it
over and see.

See the recent thread on why this hasn't been done to date.

But after watching all the fuss yesterday I decided to try to generate
the docs myself. It basically went like this:

$ sudo easy_install Sphinx
$ (cd to docs directory)
$ make html

Works for me. :)

After doing some reading about Sphinx I'm not sure why you would not
want to have it installed.

Re: Serialization

[Brian Neal]

Russ said it better than me. You simply return the serialized JSON
string as the HttpResponse. You then deserialize it somehow in the
client's Javascript code (perhaps with an "eval" statement or by the
assistance of a Javascript library like jQuery, etc.). You then have a
nice Javascript object that you can manipulate and use to add points
to the map in Javascript.

I have implemented something like this before with PHP and Javascript.
I am converting it to my Django powered site. My current client code
is straight Javascript. This time I intend to leverage jQuery to make
my code smaller, and hopefully a bit more portable.

If you want to see how I did it in plain old Javascript, my old code
can be found here:
https://sourceforge.net/projects/membermapnuke/

If you drill into the code look for mmap.js for the client side stuff
and ajax.php for the server side. I'm porting this to Django at the
moment, and I'm looking forward to trying out Django's serializer for
this.

Best,
BN

Re: Serialization

[Brian Neal]

Hi -

I'm working on a very similar problem (displaying data on a Google
map). I haven't totally implemented this yet, but my way forward is to
use AJAX to request the map data from my Django application, which
will serve it as JSON (by serializing it). You then "deserialize" it
in the Javascript code, turning it into a Javascript datastructure on
the client side. If you are using jQuery for example, jQuery will
deserialize it for you. If you are writing the Javascript by hand, you
deserialize it by doing an "eval" on the received data.

Well, I'm not sure you are catching the right exception. If you look
at the source code to get_profile() you can see it raises
SiteProfileNotAvailable, not ObjectDoesNotExist (I'm assuming you are
running trunk or something recent). However I would still expect you
to receive a 500 error for the uncaught exception.

Why don't you try running the code interactively in the python shell
and see what happens? Do something like:

$ python manage.py shell
>>> from django.contrib.auth.models import User
>>> u = User.objects.get(pk=xxx)# where xxx is a key you know has a profile
>>> p = u.get_profile()

Just make sure that works first without an exception. That may tell us
something.

It is also strange that you are passing in request.user to the
form.save(), but then you turn around and get another user object
(user_obj). Your profile is calling user.get_profile(), but you are
saving the 2nd user (user_obj.save()). Probably not your problem, but
you might want to clean up that code. I'm not sure why you are saving
user_obj anyway, you don't seem to change it. And finally your form
save() method isn't returning anything explicitly (and thus implicitly
returning None), but your form code is catching the return value
(although you don't do anything with it).

Good luck.

The user field in your MemberProfile is a CharField (I was expecting
it to be a ForeignKey to the User table).

I think the problem is you can't assign request.user to a CharField
(line 31). I'm surprised you don't get an error on line 34. Is
settings.DEBUG True?

You should also review the Django docs on all the settings. Your
MEDIA_ROOT should be a path, not a URL. Your ADMIN_MEDIA_PREFIX should
not be the same as your MEDIA_URL.

Basically you setup a directory somewhere, usually in your httpdocs
directory for your media files. That is your MEDIA_ROOT. Put your
static files there. Your admin files have to go under there too,
somehow. This can be by symlink or by copying the django admin files
in there. This is covered in the django docs on deploying under Apache/
mod_python. Your ADMIN_MEDIA_PREFIX will be put in front of any admin
static file.

Settings docs:
http://docs.djangoproject.com/en/dev/ref/settings/#ref-settings

Deploying on Apache/mod_python docs:
http://docs.djangoproject.com/en/dev/howto/deployment/modpython/#howto-deployment-modpython

Good luck!

You might want to look into using the contributed app Flatpages for
these static pages.

http://docs.djangoproject.com/en/dev/ref/contrib/flatpages/

Alternatively, in an Apache environment, you could use the location
directive to tell Apache not to send requests for certain files in a
certain directory through mod_python. This would be similar to telling
Apache not to send media files through mod_python, as discussed here:

http://docs.djangoproject.com/en/dev/howto/deployment/modpython/#id1

Maybe something like:


SetHandler None


Then put all your static html files in that directory.

As I recall, PIL out of the box only handles a very small number of
file formats. When I installed it, I had to ensure several pre-
requisites were met before PIL would handle jpegs and even gifs (maybe
- my memory is fuzzy on that one). Once I had the prerequisite
packages, I recompiled PIL and all was fine: I could then handle
jpegs.

Try this. Just get into the Python shell and try to manipulate some
images interactively. I would expect that you would be getting error
messages from Django however. But try that just to see what happens.

HmmYou haven't shown your template. Do you have the correct
enctype attribute set on your  tag?

http://docs.djangoproject.com/en/dev/ref/forms/api/#binding-uploaded-files-to-a-form

If you forgot this, the form would still validate because your image
field has required=False.

You just have to get your page to include the correct CSS and
Javascript files, just like any other editor like this. If this is a
public facing form, check out the docs on form media:

http://docs.djangoproject.com/en/dev/topics/forms/media/

If it is for the admin area, you can do something similar:

Of course you'll need some software on the server side that translates
the wiki markup to HTML. I'm not familiar with that part. But there is
great Textile and Markdown support in Django. See:

Style Question: Template tag or include?

[Brian Neal]

I have an object that I display on multiple pages. Initially I created
a little template .html file for it, and I simply

{% include 'my_object.hml' %}

every where I need it.

I have since discovered inclusion tags. Would it be better, worse, or
just different to do this instead?

{% load my_tags %}
..
..
{% display_my_object obj %}


Thanks.

Read the documentation on forms, then checkout the section on form
media:

I've integrated several jQuery plugins using both Widget and Form

Re: template tag not rendered - why not?

[Brian Neal]

I ran into this also.

I need to do a {% get_comment_form for story as form %} early on in
the template so I can do {{ form.media }} inside a block. I found that
I had to call get_comment_form twice, once in a block for CSS and once
in the block for content.

{% extends 'base.html' %}
{% block custom_js %}
{% get_comment_form for story as form %}
{{ form.media }}
{% endblock %}
.. a bunch of stuff omitted
{% block content %}
..
{% get_comment_form for story as form %}
{{ form.as_p }}
...
{% endblock %}

If I put the get_comment_form tag outside of these blocks, the render
method is never called.

Thanks.

You didn't list any admin.py code. Check out the docs on the admin
interface:

http://docs.djangoproject.com/en/dev/ref/contrib/admin/#module-django.contrib.admin

After you read through that, pay attention to the ModelAdmin media
definitions:

http://docs.djangoproject.com/en/dev/ref/contrib/admin/#modeladmin-media-definitions

It is there you specify the tinymce javascript files. When the admin
displays the form for your models it will generate the appropriate
script tags to the javascript files.

Good luck!

Yeah I would (and have) done that type of stuff there. See also the
documentation for the admin interface and overriding the save_model
method on admin.ModelAdmin. You can hang custom behavior there also,
if you only want that behavior when you save a model from the admin
interface.

I've used the PIL (Python Imaging Library) to manipulate images. Be
aware that there are other django pluggable applications that you
could use also: search for django Photologue, django-thumbs, and
django-sorl. It is fairly easy to manipulate images with PIL so I just
rolled my own. I used Photologue in a previous project, it is a
fantastic full-blown gallery app for django.

Have fun!

Sorry, posted too soon. Also, you have to send an instance of
RequestContext to your templates.

I quote from the docs again:

"
def some_view(request):
# ...
return render_to_response('my_template.html',
  my_data_dictionary,
  context_instance=RequestContext
(request))
"

So, 1) ensure your TEMPLATE_CONTEXT_PROCESSORS contains the media
processor, and then 2) pass a RequestContext to your templates.

Hope that helps,

Look at this:

Using that makes {{ MEDIA_URL }} available in your templates. Then you

Okay I think I figured it out. I studied the existing filters a bit.
You can test the input value to your filter function with "isinstance
(value, SafeData)". If so, you don't need to escape it.

Markdown filter piped into custom filter

[Brian Neal]

I wrote a filter that searches for patterns in text and replaces them
with  tags:

{{ comment.text|smilify }}

It does various silly things like replace :-) with an actual smiley
face image. Seems to work great.

When I combine it with the markdown filter, like this:

{{ comment.text|markdown:"safe"|smilify }}

It seems to escape the HTML that the markdown filter produces. In
other words if my comment text is ":-)" then the output I get (when
viewing the raw HTML source of the document) is p/p

Is it not possible to use the markdown filter like this? Or is the
markdown filter supposed to mark its output as safe and my filter is
incorrectly escaping it?

The source for my filter is here:

I'm not exactly sure what you mean, as you don't want to put a 
inside a text area without escaping it.

If you are talking about displaying text that you got from a text
area, then the PHP idiom is nl2br().

In Django templates, see the linebreaks and linebreaksbr filters:

If you use RequestContext and have the settings in your

for use in your templates. Check out:

Check out the save_model() method that you can override in your

Not sure what you are asking. I look in /etc/group to see what groups
apache belongs to. On my system, apache belongs to a group called
apache. So I did something like:

# chgrp apache uploads
# chmod 775 uploads

Instead of 0777 I use 0775. I chgrp on the uploads directory, making
the group be a group that includes the apache user.

You may not have the correct libraries installed for PIL to work with
gif's and jpegs. I think I ran into this. I believe there is something
in the PIL docs that notes this and tells you what other packages you
need to install to support those formats.

That's because you don't have a 404.html or 500.html template.

It isn't a bug. Read the docs. Create yourself an empty 404.html and
500.html file in your templates directory and your flatpage will work
with DEBUG=False.

You are almost there. You are assigning a form instance to your custom
profile's user foreign key. That is not what you want. You want to
assign the appropriate user instance to that foreign key field.

Instead of:
extraformedit.user = userformInstance

Try this:
extraformedit.user = request.user
or
extraformedit.user = userforminstance.user

Another suggestion: you probably need to check to see if both forms
are valid before going ahead with the saving.

if form.is_valid() and extraform.is_valid():

I recently did something similiar, I found my code and dpasted it. In
my case I am showing the view for a user to edit her existing profile.
I hope it helps:

Perhaps apache (or whatever user apache runs under in your system)
doesn't have permission to read/execute wherever you installed
MySQLdb?

I think I had this issue. I also ran into the "egg" issue for MySQLdb,
which is documented in the FAQ.

Yes. You need to set the user foreign key inside the extraform before
you save it. See the discussion here about ModelForms save() with
commit=False:

Technically speaking, ASCII is only a 7-bit code.

However, what is your DOCTYPE and charset on the page you are serving?
How are you displaying 'data'?

Check this out: 
http://docs.djangoproject.com/en/dev/topics/forms/#displaying-a-form-using-a-template

Try using the form.as_p or form.as_table methods. If that doesn't work
for you, you can render each field yourself.

Well..you aren't passing auth_id to the template, you are passing
form. auth_id is a field inside your template. Can you post your
template?

Well, if you worked through the tutorial you should know that you need
to run syncdb after creating a new model. Your user profile is a model
after all and it needs to reside in your database for get_profile to
work. To be honest, it seemed to me your post was a thinly disguised
jab at the docs. We all feel the way you do at first, that everything
is hard to find. But if you keep reading the docs and studying other
people's source code (check out all the django apps on
code.google.com), you'll get the hang of this.

I realize we all learn differently and at our own pace. I think that
the django docs are some of the most well written and comprehensive
docs I have seen for an open source web framework. Seriously. Have you
ever looked at another frameworks docs? If you find the docs lacking
on some point, write a Trac ticket. The developers are very responsive
to documentation requests in my one single experience. They understand
the value of good docs.

I also encourage you to get on the IRC channel. You can get fast
pointers from experts that way if you are stuck.

And finally, don't forget the actual django source code. Learning how
to navigate it and find things in it is very useful. If you are
confused about the docs, take a peek at the code. You will also learn
something about python that way.

Enjoy your experience with django!

Well...yes, in my experience it is easy to add CSS later to change the

Well you need to pass both forms to the template to get them both to

You still don't have a SetHandler None on your media directory. You
need to let Apache serve your media, not django. See

I disagree with "Django is not easy to start for a newbie". The online
docs and tutorial at http://docs.djangoproject.com/en/dev/ are
excellent and are current. The book is out of date, just use it as a
back up to the docs. Also you will get many answers in the IRC channel
and on this group.

ASCII is a 7-bit code. There is no character with the value 184 in
ASCII.

? is a special character in regular expressions, just like $, ^, etc.
You must escape it if you want to use it literally, e.g. \?. However,
I don't think the ? as part of any GET arguments in a URL are going to
be available to you, from what I remember about django works.

I'm not really following what you are trying to do however.

Well it might also just work. I am running a site with PHP, django via

I take it you mean the flat pages part of step 3? I am using TinyMCE
for admin text areas, and it works great. I've never tried it with
flat pages yet. But the reason you have to do that unregister and
register step (for flat pages only), is that because flat pages are a
contributed app, and existing code is already registering a model
admin class for it. If you want to use TinyMCE for flat pages, you
have to create your own model admin for it with the appropriate media
class, undo what the flat pages app already did by unregistering it,
then replacing it with your own.

You don't have to do all that unregister/register stuff for the models
you write.

I'm not really sure what you mean. The docs are showing you an example
of interactive Python using the shell. You don't type the above into
your program. You do know about Python's interactive shell, right?

The  Blog.objects 
business is the shell printing out the __unicode__ representation of
an object.

It is just python, really. So yes, you could do lots of things. You
could have a server running in C++ that your python app hands the
calculations off to. The C++ app could even send the results back to
your python code to store in the database. You have lots of options.

Okay. I am using TinyMCE with many textareas on my site, however I
have not tried it with flatpages yet, so I can't vouch for those
instructions on the wiki. Can you activate it on a "normal" model in
the admin area? That might narrow it down.

Check out the django Photologue application. It's really slick. You
can upload through the admin interface a zip file of photos and it
will create a gallery for you from that. It also automatically resizes
photos according to a set of sizes you specify, and creates them only
on demand.

As for your question about how to make your own admin apps, check out
the online Django book, which has a chapter on how to do that
(suprisingly this isn't really covered in the online Django docs).

In addition to what has already been mentioned, it is also handy to
define convenience functions on your model classes that return
information like this. So your model could be given a total_price()
member function that calculates it based upon member data. These
convenience functions are easily accessed in the template.

djandrow, you may also consider using a "slug field" instead of the
category name for your urls if you don't like the url encoding. Many
people do not like spaces in URL's. A slug is a unique key for each
category that is made up of letters, digits, and the dash (-)
character.

Maybe use a honeypot field in the form like the comments app does. You
can even label it with a label that says "do not fill in this form or
we will think you are spamming us". Hide this field on the form with
CSS (display: none) so most users with modern browsers won't even see
it. Spammers using automated tools typically fill in random garbage
into all fields on a form. Reject any form submission that has that
field filled in.

Sounds reasonable. However I am using a RadioSelect widget in my "rite-
of-passage" first Django poll app. It looks very weird to see this on
a form (please forgive the crude ASCII art):

Vote Now:
* 
* Yes
* No
[Submit]

However I looked at the django source code and found that you can set
empty_label to None to get rid of that first choice. Here is how I did
it in my form class:

from django import forms
from gpp.polls.models import Choice

class VoteForm(forms.Form):
   """Form for voting in a poll."""
   options = forms.ModelChoiceField(queryset = Choice.objects.none(),
widget = forms.RadioSelect)

Huh? They were just as specific to django as yours were.

No, I was pointing out there may be other issues beyond the ones you

That's great that you got it working, but that isn't always the case.
Some hosts will not allow you to edit/have your own .htaccess files or
edit the main httpd.conf file. In addition, I found that I needed a
PYTHON_EGG_CACHE, a directory where apache could write to to extract
eggs. Some hosts aren't going to let you have shell access to chmod a
directory to allow this. Yes it can be done but you may have to work
with your host or purchase your own dedicated hosting.

Does that profiles_edit_profile function exist somewhere? Is that
urls.py in an application that is listed in your INSTALLED_APPS
setting?

What exactly are you having problems with? The tutorial covers the
usage of the development server quite well. Are you having problems
getting the package, unpacking it, what? What step in the tutorial has
you stumped? Really, I don't want to seem patronizing, but the
tutorial does tell you what you need to do.

I am developing on Windows using the development server. I have also
setup Apache and mod_python on Windows with the XAMPP package using
the instructions on the django doc site. And finally I have setup
Apache and mod_python on a linux server using the same instructions.
The docs don't give every last detail for an apache setup, but if you
are familiar with apache it is not hard at all. But, as Karen said,
for learning and development, the development server is the best and
easiest option.

That was my fallback. In my case that would mean 8 URLs or so. Not too
bad.

However I just tried naming my pattern and referencing that from the
template, and it worked!

Re: Problem with url tag (Caught an exception while rendering: Reverse ...)

[Brian Neal]

I might have found my answer. I was looking at the list of
incompatible changes and found this:

http://code.djangoproject.com/changeset/8760

Which led me to this:

http://docs.djangoproject.com/en/dev/topics/http/urls/#reverse

I quote from the docs:

"The reverse() function can reverse a large variety of regular
expression patterns for URLs, but not every possible one. The main
restriction at the moment is that the pattern cannot contain
alternative choices using the vertical bar ("|") character. You can
quite happily use such patterns for matching against incoming URLs and
sending them off to views, but you cannot reverse such patterns."

This is exactly what I am trying to do. My pattern is using the |
alternation. So apparently the url tag eventually calls reverse and it
is failing to find my pattern.

Hmmm, it isn't crystal clear (to me anyway) that you are supposed to
drop the application name. It says "The first argument is a path to a
view function in the format package.package.module.function.". That is
what I am doing: gpp.weblinks.views.view_links. Futhermore, this is
how I have been doing it since I started using django a few months
ago. Is there fallback logic in the url resolver logic that undoes
what I am doing?

Anyway, I will try it, but I believe I did already.

I am also seeing strange things if I change the order of the URLs in
my URL patterns list.

Problem with url tag (Caught an exception while rendering: Reverse ...)

[Brian Neal]

This is my urls.py for an app (notice the two that start with
^category/, they both vector to my function view_links):

from django.conf.urls.defaults import *

urlpatterns = patterns('gpp.weblinks.views',
   (r'^$', 'link_index'),
   (r'^add/$', 'add_link'),
   (r'^category/(?P\d+)/$', 'view_links'),
   (r'^category/(?P\d+)/(?Ptitle|date|rating|hits)/(?
Pup|down)/(?P\d+)/$', 'view_links'),
   (r'^new/$', 'new_links'),
   (r'^popular/$', 'popular_links'),
   (r'^random/$', 'random_link'),
   (r'^top_rated/$', 'top_rated_links'),
   (r'^visit/(\d+)/$', 'visit'),
)

This is my signature for my function view_links in gpp.weblinks.views:

def view_links(request, category, sort = 'title', dir = 'up', page =
'1'):

If I type these links manually into my browser, they both work. Each
exercises one of my urlpatterns that start with category: (note that I
have a parent urls.py that looks for "^links/" and then includes the
above urls.py)

http://localhost:8000/links/category/1/
http://localhost:8000/links/category/1/title/up/2/

However when I try to then add the following bit of stuff to my
template, then visit http://localhost:8000/links/category/1/, I get an
error.

   {% if page.has_next %}
   
  Next Page
   {% endif %}

Here is Traceback for the error that I get. Notice that in the error
message it says this: "Reverse for
'gpp.gpp.weblinks.views.view_links' ... ".  Why is gpp on there twice?
It should just be gpp.weblinks.views.view_links. Anyway, here it is:
