why I get three password fields when I define my custom registration form in Django?

Question

I am defining a custom registration form that includes email Field in it. Here is the code:

forms.py:

from django import forms
from django.contrib.auth.models import User
from django.contrib.auth.forms import UserCreationForm

class MyRegistrationForm(UserCreationForm):
    #define fields
    email=forms.EmailField(required=True)

    class Meta:
        model=User
        fields=('username','email','password','password2')

        def save(self, commit=True):
            user = super(MyRegistrationForm, self).save(commit=False)
            user.email=self.cleaned_data["email"]
            if commit:
                user.save()
            return user

views.py:

def register_user(request):
    if request.method=='POST':
        #form=UserCreationForm(request.POST)
        form=MyRegistrationForm(request.POST)
        if form.is_valid():
            form.save()
            return HttpResponseRedirect("/accounts/register_success")

    args={}
    args.update(csrf(request))
    #args['form']=UserCreationForm()
    args['form']=MyRegistrationForm()
    return render(request,"register.html",args)

templates/register.html:

{% extends "base.html" %}

{% block content %}
<h2>Register</h2>
<form action="" method="post">{% csrf_token %}

{{ form }}

<input type="submit" value="register"/>

</form>
{% endblock %}

As you can see from the attached screenshot, I get three password Fields. why is that? A similar question is asked here, but no solution is provided.

Answer 1

I guess it is because you are defining a new password field. your fields in class Meta should be as follows:

class Meta:
        model=User
        fields=('username','email','password1','password2')

In this case, you are inheriting the fields from UserCreationForm.
