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

[Ryan Alexander]

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 = ????

Many thanks in advance,

Ryan

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()

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.
