Hey there,

This seems like something that should be simple to do but I'm having a 
heck of a time with it and google searches don't reference anything 
that's helping me out.


I have a form that a user fills out, and it creates a db row based on 
the input.  Model as below:


class Accounts(models.Model):
authid = models.CharField(max_length=128)
authtoken = models.CharField(max_length=128)
provider = models.ForeignKey(Provider)
user = models.ForeignKey(User, unique=True)


How do I feed the current user value to the form?  Form code:

class AccountForm(forms.ModelForm):

  provider = forms.ModelChoiceField(queryset=Provider.objects.all(), 
help_text="Provider")

  authid = forms.CharField(max_length=256, help_text="AuthID")

  authtoken = forms.CharField(max_length=256, help_text="AuthToken")

   user = 

If you are using a class based view like CreateView you can set the 
current user in the form_valid method like this:


def form_valid(self, form):
form.instance.user = self.request.user

Furthermore you don't need to define a modelform when using CreateView.

Re: FORM: How to specify current user as value for a form ForeignKey referencing logged on user

[Vijay Khemlani]

If you are using a modelform then you don't need to re-define the original
model fields, in this case

Class AccountForm(forms.ModelForm):
class Meta:
model = Accounts
fields = ['authid', 'authtoken', 'provider']

You leave the "user" field out as it is not part of the form itself

Then in your view you can do something like this:

form = AccountForm(self.request.POST)
if form.is_valid():
instance = form.instance
instance.user = self.request.user
instance.save()
