Comment:
The patch I sent seems to work quite oki, but if I add a field dynamicaly,
even if it's in the form object, the new value is not saved:
{{{
def dynamic_fieldsets(self, request, obj=None, **kwargs):
general_fields = list(self.general_fields)
perms = PagePermission(request.user)
if perms.check('freeze'):
general_fields.append('freeze_date')
return [
[_('General'), {
'fields': general_fields,
'classes': ('module-general',),
}],
(_('Options'), {
'fields': self.normal_fields,
'classes': ('module-options',),
}),
]
}}}
My freeze field is added properly in the admin interface, but the value is
not saved. But in the other hand if I do things like that:
{{{
def get_fieldsets(self, request, obj=None):
"""
Add fieldsets of placeholders to the list of already
existing fieldsets.
"""
general_fields = list(self.general_fields)
perms = PagePermission(request.user)
# some ugly business to remove freeze_date
# from the field list
general_module = {
'fields': list(self.general_fields),
'classes': ('module-general',),
}
default_fieldsets = list(self.fieldsets)
if not perms.check('freeze'):
general_module['fields'].remove('freeze_date')
default_fieldsets[0][1] = general_module
}}}
The latest version works, but it feels like a very hackish way to do
things.
Can somebody explain me what's wrong here? Does Django have a more elegant
way to do this?
