Creating a form
Django already has a User model which can create, remove and edit users. We will use all the built in functionality. We therefore only need to create a form. So in a new python ('.py') document enter the following:
from django import forms
from django.contrib.auth.models import User
from django.contrib.auth.forms import UserCreationForm
class UserRegistrationForm (UserCreationForm):
email = forms.EmailField(required=True)
first_name = forms.CharField(required=True)
last_name = forms.CharField(required=True)
class Meta:
model=User
fields = [
'username',
'first_name',
'last_name',
'email',
'password1',
'password2',
]
Now save this in the 'users' app folder, and call it 'forms.py'.
Create a view
Now in the 'views.py' file within your 'users' app folder, add the following import:
from .forms import UserRegistrationForm
from django.contrib import messages
Now we need to declare the view, enter the following:
def register(request):
if request.method=='POST':
form = UserRegistrationForm(request.POST)
else:
form = UserRegistrationForm()
return render(request, 'users/register.html', {'form':form})
The if statement is to check if the page has form data or not. If it doesn't the form will be empty, and if it does we grab the data and put it into the form.
Check the data
Now we have a form, and have the form data we need to check the form. So after the line 'form = UserRegistrationForm(request.POST)' add the following code:
if form.is_valid():
username = form.cleaned_data.get('username')
email = form.cleaned_data.get('email')
first_name = form.cleaned_data.get('first_name')
last_name = form.cleaned_data.get('last_name')
form.save()
messages.success(request, 'Your account has been created! Now you can login!')
else:
form = UserRegistrationForm(request.POST)
messages.success(request, 'Error in creating your account, the form is not valid!')
return render(request, 'users/register.html', {'form':form})
This code will check the form is valid, if it is then the data is cleaned from the form and finally saved. A message is created to tell you the account was created. If the form isn't valid it will retain the form data and display a message to say the form was invalid.
Final view
This should be your final view:
def register(request):
if request.method=='POST':
form = UserRegistrationForm(request.POST)
if form.is_valid():
username = form.cleaned_data.get('username')
email = form.cleaned_data.get('email')
first_name = form.cleaned_data.get('first_name')
last_name = form.cleaned_data.get('last_name')
form.save()
messages.success(request, 'Your account has been created! Now you can login!')
else:
form = UserRegistrationForm(request.POST)
messages.success(request, 'Error in creating your account, the form is not valid!')
return render(request, 'users/register.html', {'form':form})
else:
form = UserRegistrationForm()
return render(request, 'users/register.html', {'form':form})
Register template
In the 'templates' folder in the 'users' app, copy the 'login.html' and duplicate it. Change the name to 'register.html'.
Edit your new 'register.html' and change references to 'Login' to 'Register':
{% extends "MyApp/base.html" %}
{% block content %}
<h2>Register</h2>
<form method="post">
{% csrf_token %}
{{ form.as_p }}
<button type="submit">Register<button>
</form>
{% endblock %}
Set URL
Now in the 'urls.py' file in the project folder (mine is called 'MyProject'), add the new path in the 'urlpatterns':
path('register', user_views.register, name='register'),
