Short intro

So, I've been using Django for a while now and thought it would be nice to start a simple application. In an ideal World, each app must have a way of letting its users register and that's what I'm gonna do below.


I've used the latest Django version for this project -> because of this, I couldn't use django-registration module as it's incompatible with the above. Apart from this, I've used Python 3.6.5.

What I want to do it's common along other web applications:

  1. The user goes to the registration page and fills in the following fields:

    • first_name
    • last_name
    • email
  2. The user submits the form and receives a confirmation email with an URL containing a unique token.

  3. When the user clicks on the received link, he's redirected to a page where he'll set his password.

  4. When done, he's logged in to the dashboard page.

Things that I'd like to be reviewed:

  • Django Design Patterns: Did I use the correct views / forms / models in my app? Should some of the logic be written somewhere else etc...
  • Security: Is my register system secure? If not, what can I do to make it so?
  • General feedback: Anything that comes to your mind is welcome (including criticism, ideas, improvements, cats...aliens..)
  • 3
    \$\begingroup\$ It could be worth putting your code and templates in a public repo for people to clone, to make it easier to review \$\endgroup\$ – James Hiew May 24 '18 at 6:36
