Re: creating an api using python

Re: how can I clean a form field before the clean method?
Yes, you have reason. I prefer use something like an "exclude" or "fields" tuple in the form meta, and set default values in the model to the fields that I need, but some of the default values are foreign keys. I want to do something like: .default = MyModel.objects.get(field=True) and raise an exception if don't find in the table a row with a field = True, but I don't have idea if something like this can be done.

Nuts. What if you remove the first TRANSLATE call, i.e.
cursor.execute(r"SELECT 1 FROM DUAL WHERE 'A' LIKE TRANSLATE('A' USING

If that also doesn't trigger the error, then maybe we need an actual

Class based views list view logic
Hi i m trying to use class based views on my project.
I've read the documentation but i couldnt determine it well.
what i'm trying to do is just use simple list of items of selected menu.
i have 2 classes on my model. Menu and MenuItem. Menu corresponds of
food menu types of a cafe; like "wine menu" "beef menu" ... and MenuItem
is sub item of menus. like in "Wıne menu": "red wine" or "white wine" or
some other kind of wine. but i couldnt get the list of items in the
menu.here is my models views urls and template.
models:
#!/usr/bin/env python

from photologue.models import Photo

Re: Class based views list view logic
This example should help you:
http://docs.djangoproject.com/en/dev/topics/class-based-views/#dynamic-filtering
``self.args`` and ``self.kwargs`` contain the groups matched in the
URL, so I guess you want to use ``self.args[0]`` as your Menu name.
One thing I don't understand is, why you sometimes write "Food" and
sometimes "MenuItem". Is that the same model ?

However, it sounds as though you want to build a dynamic form (some fields set dynamically, in response to certain conditions), but NOT have the user mess with these things. The ways you mention to keep the fields out of the form are the normal ways, but if you are going to build a dynamic form without doing it in the POST view, etc., you would normally do it with a custom __init__ method for the form. But since the fields have been excluded, I think this would put you back into the problem of marking form fields as hidden or something. This kinda gets to be a circular problem primarily because the function of a form is to accept user input, not hide it. I'm sure you can do it, but it really just becomes a case (in my opinion) of trying to pound a square peg into a round hole. If I understand you correctly, my advice would be to validate the data in clean(), and then to handle the object lookup in a pre_save() signal catcher (in the model) and bail from there if the value isn't found. > Thanks for read and sorry for my newbies questions.

If so, then like I mentioned, it should suffice to do something like: r'^(?P\w+)/(?P\w+)$', 'view_to_pass_to' to match against. It will then call the view you specify, and pass the kwargs main_obj and page_obj. You can then look up these two slugs in your db, check if they exist, find all page_objs that link to main_obj, etc. -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: not able to see models.DecimalField in template
I really don't have an answer to the question. Instead of asking whether or not you should convert to unicode, I think you should have converted first to unicode and see what happens. If that doesn't work, then you ask for help. It is just normal that you've used up all options you can think of before asking for help. That option you least think of in most cases works the magic.

Re: how can I clean a form field before the clean method?
Sure. Just override the clean method for the field, or the whole form if you wish. The built-in "default" validation done by Django doesn't handle any logic; it just makes sure the format and type of each field is appropriate.

UTF-8 support in custom tags
Hi,
I'm trying to write a custom tag that does a very simple action: sets
the value into a variable. E.g.
{% set variable %}The value{% endset %}
Here's the essential part of the code (omitting some details):
def set_tag(parser, token):
nodelist = parser.parse(("endset",))
parser.delete_first_token()
return SetValueNode(arg, nodelist)
class SetValueNode(template.Node):
def __init__(self, variable, nodelist):
self.variable = variable
self.nodelist = nodelist
def render(self, context):
context[self.variable] = self.nodelist.render(context)
return ""
Everything works great while I'm using ASCII symbols in a template
(between set and endset tokens). But once I add UTF-8 symbol I get
Caught an exception while rendering: ('charmap', u'\u041e
\u0442\u0432\u0435\u0442\u044b: ', 0, 6, 'character maps to
')
In a trace dump I noticed that this is UnicodeEncodeError, occurring
in "self.nodelist.render(context)".
Any ideas how to deal with it?

The Unicode documentation has specific information

Re: Need a tip on how to architect this code to be more extensible
I still haven't came up with a creative solution on this, is there
anyone that might be able to give me some ideas?

Re: UTF-8 support in custom tags
Hi Ramiro,
Thanks for tip. Setting
DEFAULT_CHARSET = "UTF-8"
FILE_CHARSET = "UTF-8"
did the trick, though I thought it is UTF-8 by default and doesn't
have to be set explicitly.
Anyway now everything's working. Thanks!
