This is somewhat related to my previous post. I didn’t want to include my user profile value in the form and instead add it during validation. This caused the model validation to be skipped in part. I had to do some gymnastics to get it to run.<\/p>\n
In this latest attempt, I have instead included that profile as a hidden field and compare it to the current user profile. Much cleaner! Now all I have to to is get that current value into the form.<\/p>\n
It didn’t take long on Google to find several examples. Here is my rendition:<\/p>\n
In the view, I overrode the get_form method to add the profile as a paramter<\/p>\n
def get_form(self, form_class=None):\r\n\r\n if form_class is None:\r\n form_class = self.get_form_class()\r\n return form_class(**self.get_form_kwargs(),current_user_profile=get_profile(self.request.user))<\/pre>\nNext, in the form I need to pop that value from the kwargs dictionary as assign to a object variable<\/p>\n
class LinkForm(ModelForm):\r\n\r\n def __init__(self, *args, **kwargs):\r\n\r\n self.current_user_profile = kwargs.pop('current_user_profile')\r\n\r\n super(LinkForm, self).__init__(*args, **kwargs)\r\n\r\n self.fields['profile'].widget=HiddenInput()<\/pre>\nI also set the profile field to hidden here.<\/p>\n
Now I can write a clean method for the profile field like so:<\/p>\n
def clean_profile(self):\r\n\r\n profile = self.cleaned_data.get('profile',None)\r\n\r\n if profile != self.current_user_profile:\r\n self.add_error(None,ValidationError('Web page altered. Try again.', code='wrong_profile'))\r\n\r\n return profile<\/pre>\nThis is much easier and clearer than my previous method. Not bad for working late on a Wednesday night.<\/p>\n","protected":false},"excerpt":{"rendered":"
