Django user registration and logon: Django User Registration

Django user registration and logon: Django User Registration

Django is a free open-source website framework developed by Python. It can be used to quickly build high-performance and elegant websites!

It is very difficult to learn django, and it is so difficult to get the simplest user logon and registration interface recently. At present, it is basically implemented. Although the function is particularly simple, it makes a record, further study will be provided in the future:

First, create a project and go to the project directory: django-admin startproject demo0414_userauth

Go to project: cd demo0414_userauth

Create the corresponding app: django-admin startapp account

Structure of the entire project

── Account
│ ── Admin. py
│ ── Admin. pyc
│ ── Apps. py
│ ── Init. py
│ ── Init. pyc
│ ── Migrations
│ ── 000w.initial.py
│ ── 000w.initial.pyc
│ ── Init. py
│ ── Init. pyc
│ ── Models. py
│ ── Models. pyc
│ ── Tests. py
│ ── Urls. py
│ ── Urls. pyc
│ ── Views. py

│ ── Init. py
│ ── Init. pyc
│ ── Settings. py
│ ── Settings. pyc
│ ── Urls. py

│ ── Wsgi. py
│ ── Wsgi. pyc
── Manage. py
└ ── Templates
── Register.html
├ ── Success.html
── Userlogin.html

4 directories, 29 files

Then add the app account to the installed_app of the setting file;

 

Create a templates folder, which can be placed in the project root directory or app directory. Generally, it is recommended to store them in the app directory. If you put down the root directory of the project, you must set 'dirs': [OS. path. join (BASE_DIR, 'templates')] In the setting file. Otherwise, the template cannot be used.

 

In addition, due to the page Jump problem in this project, in order to prevent csrf attacks safely, related settings are available in one template. At present, I still don't use this item. It is said that adding label {% csrf_token %} to form can be implemented, but I have not succeeded. So ignore this issue and comment out the middleware 'django. middleware. csrf. CsrfViewMiddleware 'in seeting.

 

Then, create the corresponding database in the model:

class User(models.Model): username = models.CharField(max_length=50) password = models.CharField(max_length=50) email = models.EmailField()

View. Pdb was used for breakpoint debugging. I like it very much. If you are not interested, just comment it out.

The Tempaltes folder contains three pages:

Register.html

<? Xml version = "1.0" encoding = "UTF-8"?> <! DOCTYPE html PUBLIC "-// W3C // dtd xhtml 1.0 Strict // EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
