Two models one form, or use generic CreateView

[The Sha]

Hi 

I hava a problem in django, i have to models one is a CustomUser Model and the other is a Address model. 

The problem is that when i create a generic CreateView for the Address model and use a pk: url the address form wont get the instance of the users PK for adding a new address.

my models look like this, Even though i pass the PK in the URL the CreateView does not understand that i want to add a address to user with id: 42 in this example. How can i solve this problem?

The URL

 path('<int:CustomUser_id>/address', views.AddressCreateView.as_view(), name='Address-add'),

This is my view

class AddressCreateView(CreateView):

    model = Address

    template_name = 'members/address_form.html'

    success_url = reverse_lazy('MemberIndex')

    fields = ('CustomUser', 'address', 'zip_code', 'city', 'state','active')

The model

class CustomUser(AbstractBaseUser, PermissionsMixin):

    email = models.EmailField(_('email address'), unique=True)

    personal_Id = models.CharField(max_length=12, blank=False)

    first_name = models.CharField(_('first name'), max_length=30, blank=True)

    middle_name = models.CharField('middle name', max_length=30, blank=True)

    last_name = models.CharField(_('last name'), max_length=30, blank=True)

    is_staff = models.BooleanField(default=False)

    is_active = models.BooleanField(default=True)

    date_joined = models.DateTimeField(default=timezone.now)

    avatar = models.ImageField(upload_to='images', blank=True)

    def __str__(self):

        return self.email

    def full_name(self):

        return '%s %s %s' % (self.first_name, self.middle_name, self.last_name)

    USERNAME_FIELD = 'email'

    REQUIRED_FIELDS = []

    objects = CustomUserManager()

class Address(models.Model):

    CustomUser = models.ForeignKey(CustomUser, on_delete=models.CASCADE)

    address = models.CharField(max_length=60, blank=False)

    zip_code = models.CharField(max_length=8, blank=False)

    city = models.CharField(max_length=30, blank=False)

    state = models.CharField(max_length=30, blank=False)

    active = models.BooleanField(name='active', default=True, editable=True)

    address_reg_date = models.DateTimeField(default=timezone.now)

    class Meta:

        verbose_name_plural = "Address"

 

    def __str__(self):

         return self.address +', '+ str(self.zip_code) + ', ' + self.city

There's many ways to solve it. My favorable approach will be to override the save method in the targeted form.

It's pretty straight forward, just search about overload save function for update view, that will make u create a save function in your form, do the necessary actions on your instance, and voula

Hi Sha, 

I like your template CSS styling and formatting. 

Could you please post your index HTML and CSS style if you don't mind.

Thanks in Advance

Your code is fine but you will need to preload your form with the customer which you want this can be done in the get method of that create view.Read more about  use of DjangoModel form

https://docs.djangoproject.com/en/3.1/topics/forms/modelforms/

Then override the get() method  and respond with the form populated with the customer details  .

Alternative use javascript to just take the  pk from your url 

Alternatively  pass it as a separate argument in your context  by again overriding the get() method.

Personally will do it right way using  model forms

You could use InlineFormSet, which is designed specially to handle such problems. Refer to the documentations here https://docs.djangoproject.com/en/3.1/topics/forms/modelforms/#inline-formsets 

Here you could provide the primary model (in your case it will be CUstomUser), and the secondary model (which will be Address).

Something similar to below.

from django.forms import inlineformset_factory
CustomerFormSet = inlineformset_factory(CustomUser, Address, fields=('email', 'firstname', ......  'address','zipcode',....))

  Hope this helps. 

 

Thanks & Regards,
