I have created multiple forms for signup with extending abstractuser model. also I have put all these forms in template separately. Is it the correct way to handle multiple forms. Facing issue in the line (vendordetail.save()) Not null field (onetoonefield related issue). But I don't know how to write views for this all forms. Please help me to get this solved.

CodePudding user response：

Where are you inserting the correct vendoruser? That needs to be filled in prior to calling save().

You need to do something like:

vendordetail.instance.vendoruser = request.user

If indeed vendoruser is the user that's currently logged in, else you need to get it from somewhere else. After insertion you can call:

vendordetail.save()

Edit: I missed that you are creating your user on the same page in another form. In that case you can first save your user form:

new_user = form.save()

The save() method of a model form will return the new object, therefore you can use it afterwards for your other forms:

vendordetail.instance.vendoruser = new_user
