I have an inline model formset, and I'd like to make fields non-editable if those fields already have values when the page is loaded. If the user clicks an "Edit" button on that row, it would become editable and (using JavaScript) I would replace the original widgets with editable ones. I'd like to do something like this when loading t...

At some point I need to display a "disabled" (greyed out by disabled="disabled" attribute) input of type "select". As specified in the standard (xhtml and html4), inputs of type "select" can not have the "readonly" attribute.

Django is making very nice forms after creating a models.py and an admin.py.
How can I reuse these forms (with the extra nice handling of foreign keys and many-to-many fields) in my own views?
ModelForm does only generate "simple" forms. Where do I get the extra batteries?
...
Example, for this form:
>>> class CommentForm(forms.Form):
... name = forms.CharField(initial='class')
... action = forms.ChoiceField(...)
Can I have the choices in the action field be different depending on what is in the name field?

I've got a form which includes the option to upload an image. In my model, I've defined a default image name to use when no image is selected for upload. When selecting a file, the form uploads the file to my media directory and properly places the filename in the db field (working as it should). When not selecting a file, that field ...

ordering = ('ordenacao',)
#prevent equally named menus within a store(loja)

I display a formset, which has Forms populated by the objects returned by a queryset.
The problem is that before the user submits items are modified or added, such that the queryset returns objects in a different order.
The formset then associates each form with the wrong object, users report that their data is shifting down by 1 row.

The Django admin happily supports many-to-one and many-to-many relationships through an HTML <SELECT> form field, allowing selection of one or many options respectively. There's even a nice Javascript filter_horizontal widget to help.
I'm trying to do the same from the one-to-many side through related_name. I don't see how it's much dif...
