Django Relationship :- User Email Not Showing

[mihir-patel535535]

I Have Created Project Using Custom User Model & I Have Used Relationships To Get Users, But I Am Unable To Get User Email Addresses In Relationship Field

Here Is Models.py File

from django.db import models
from django.contrib.auth.models import (
    BaseUserManager,
    AbstractBaseUser,
    PermissionsMixin,
)


# Create your models here.
class User_Manager(BaseUserManager):

    def create_user(self, email=None, password=None, **extra_fields):
        user = self.model(email=self.normalize_email(email))
        user.set_password(password)
        user.save(using=self._db)
        return user

        extra_fields.setdefault("is_superuser", True)
        extra_fields.setdefault("is_active", True)
        extra_fields.setdefault("is_admin", True)

        if extra_fields.get("is_staff") is not True:
            raise ValueError("Superuser must have is_staff=True.")
        if extra_fields.get("is_superuser") is not True:
            raise ValueError("Superuser must have is_superuser=True.")

        return self.create_user(email, password, **extra_fields)

You need to post the relevant code (and/or) templates here showing what you’re trying to do.

Note, when posting code here, enclose the code between lines of three backtick - ` characters. This means you’ll have a line of ```, then your code, then another line of ```. This forces the forum software to keep your code properly formatted, which is critical with Python.

[mihir-patel535535]

Sir, I Just Edited The Code

[KenWhitesell]

Yep, I see that. So what specifically in that code is not working as intended?

[mihir-patel535535]

Everything is Fine, First It Was Showing Me An Error Due To Not Adding null=True In Relationship Field In Model " Django Integrity Error : NULL Constrained Failed "

After That i Kept null=True In Relationship Field Then It Is Stop Showing Me Error But It is Not Showing Me User Email Which Is Unique Field In My User Model

[mihir-patel535535]

Have You Find Any Error In Coding ?

[KenWhitesell]

Changing null=True is addressing the symptom and not the real problem.

You’ve got a couple different issues here.

• Your contact_website_view does not set the user_email field in the instance of Contact_website being created.

• Your user_email field in Contact_website is misnamed. It’s a foreign key field, which means it’s a reference to an instance of the User_signup model, not the email field within that instance.

• Your validation of first and last names not being the same don’t belong in a clean_fieldname method. Validation accessing more than one field should be done in the form’s clean method.

• You have a clean_rpassword method that doesn’t appear like it’s ever going to be used.

• You shouldn’t be calling super().clean() within a clean method. The form class makes the cleaned_data dict available as an attribute of that class, accessible using self.

• You have a lot of code to copy values in your fm.is_valid block that aren’t needed when you use a model form.

• There’s no reason to make both password and password2 fields in your model.

• To avoid confusion in the future, I strongly suggest you adopt Django’s coding conventions regarding class and attribute names.

And these are just the things I spotted right off-hand.

I suggest you review the docs for:

• Working with forms | Django documentation | Django
• Form and field validation | Django documentation | Django
  and
• Creating forms from models | Django documentation | Django

You may also consider it worthwhile to look at the forms created by the Admin for the built-in user class.

I Made Changes To Identify User in Contact Website Form As Below

def contact_website_view(request):
   
    if request.method == 'POST':
        fm = Contact_website_form(request.POST)
        if fm.is_valid():
            fm.save(commit=False)
            fm.instance.user_name=request.user
            fm.save()
            success_id = 3
            return redirect(f'/success_responce/{success_id}/')
    else:
        fm = Contact_website_form()
    return render(request, 'news/contact_website.html', { 'user': request.user,'form': fm})```

But It Is Still Not Saving Form, And Not Even Showing Any Error .

[KenWhitesell]

The easiest way to diagnose this would be to add some print statements at the appropriate points within this view to see what the data is that you are receiving and understanding why certain code-paths are being taken.

[mihir-patel535535]

In forms.py I Have Used Below Code

class Contact_website_form(forms.Form):
    class Meta:
        model = Contact_website
        fields = '__all__'

I Tried With forms.ModelForm And Tried To Print Output But It Is Not Saving Form And I Am Unable To Access Another Model Using User Model by Applying Query Like {{user.Contact_website.website_message}}

For Above Code I Have Written View Code Like This

@login_required(login_url='/userlogin')
def contact_website_view(request):
   
    if request.method == 'POST':
        fm = Contact_website_form(request.POST)
        
        if fm.is_valid():
            website_message  = fm.cleaned_data.get('website_message')
            user1 = Contact_website(
                                  user_name = request.user,
                                  website_message=website_message,
                                  
                                  )
            user1.save()
            success_id = 3
            return redirect(f'/success_responce/{success_id}/')
    else:
        fm = Contact_website_form()
    return render(request, 'news/contact_website.html', { 'user': request.user,'form': fm})

And With Using Forms.ModelForm
I Had Wrote View Like This, But Is Was Unable To Save Form

def contact_website_view(request):
   
    if request.method == 'POST':
        fm = Contact_website_form(request.POST)
        if fm.is_valid():
            fm.save(commit=False)
            fm.instance.user_name=request.user
            fm.save()
            success_id = 3
            return redirect(f'/success_responce/{success_id}/')
    else:
        fm = Contact_website_form()
    return render(request, 'news/contact_website.html', { 'user': request.user,'form': fm})```

I have suggested you add some print statements to your view to show you what data you’re working with at each step.

Please post the view with the print statements you have added along with the output generated by those statements from your console.
