Following Django Tutorial (CRM)-Part9

This post is for myself to remember how to build Django project.
I did follow the tutorial from the JustDjango Learn website free tutorial.
And this is the fourth tutorial named Getting Started With Django.
I am not going over all the details and descriptions for each part. There are good explanations on video of the JustDjango Learn. So, visit their site and try their tutorials if you need more details. Also, the orders of this post and their video might be different because I put things first what I think should come first.

I am doing this on Windows 10 with just Windows PowerShell. Not using virtual machines at all.

1. built-in authentication source code provided by django

to see the source code go to
env -> bin -> lib/python -> site-packages -> django -> contrib -> auth -> views.py
the above path is from the video, but my local has little different.

for the description, please see their video about authentication

2. create login

create registration folder under template
create login.html file under registration folder
write/copy code below

{% extends 'base.html' %}

{% block content %}

<form method="post">
	{% csrf_token %}
	{{ form.as_p }}
	<button type="submit">Login</button>
</form>

{% endblock content %}

go to urls.py under root project folder, djangocrm in my case
import Loginview and add path for login like screenshot below

save files and go to “http://localhost:8000/login/” to check if the login page shows
since we have superuser already, you should be able to login with superuser
if you try to login, you will see error like below screen

this means you are logged in, but the url “http://localhost:8000/accounts/profile/” is defined as default by django after login
to change the redirect page after login, go to settings.py
add code below at the bottom

LOGIN_REDIRECT_URL = "/leads"

after save the file, test to login again
after you logged in, you don’t know you are logged in now.
to show you are whether logged in or not, go to navbar.html
add code like below screenshot

3. create logout

go to urls.py under root project folder
import LogoutView
add path

go to navbar.html
add href link for logout

4. Create Signup

there is no signup view in source code, so need to create our own
create signup.html under registration folder
copy content from login.html and just change “Login” to “Signup”

go to views.py under leads folder
import UserCreationForm
add SignupView class

class SignupView(generic.CreateView):
	template_name = "registration/signup.html"
	form_class = UserCreationForm

	def get_success_url(self):
		return reverse("login")

go to urls.py under djangocrm folder
import SignupView and add path

go to navbar.html
add href link for signup

save files, go to browser, if you are logged in, log out
go to home or lead list page
click signup button
signup for test user

you will see this kind of error
this is because user is defined as built in django model user
to make it custom model, go to forms.py under leads folder
import some and add class there like below screenshot

go to views.py
import CustomUserCreationForm from .forms
and get rid of UserCreationForm
replace UserCreationForm to CustomUserCreationForm on class

save files and try to signup again and try login
to see users logout from the test user, login again with superuser
go to http://localhost:8000/admin/ and go to Users tab.

5. tests

again, I am not going over all the details, for the description of each of them, please go to their site and watch the video.
below steps are for when the projects getting bigger. and it is explained almost at the end of the video.
create folder name tests
create init file
move tests.py into tests folder and rename it, and create another file

write/copy code below on test_views.py

from django.test import TestCase
from django.shortcuts import reverse

# Create your tests here.

class LandingPageTest(TestCase):

	def test_get(self):
		response = self.client.get(reverse("landing-page"))
		self.assertEqual(response.status_code, 200)
		self.assertTemplateUsed(response, "landing.html")

stop the server on console
type “python manage.py test”
see the result
