竟然还是Django 【关于template_dirs的设置】 搞了我一个小时，脑残了

template的默认目录在安装的目录里。所以要project 下重新设置。

找到setting.py
加上

mysite/settings.py

TEMPLATE_DIRS = [os.path.join(BASE_DIR, 'templates')]

这是目录：.

├── db.sqlite3
├── jason_auth
│   ├── admin.py
│   ├── __init__.py
│   ├── __init__.pyc
│   ├── migrations
│   │   └── __init__.py
│   ├── models.py
│   ├── tests.py
│   ├── urls.py
│   ├── urls.pyc
│   ├── views.py
│   └── views.pyc
├── jason_pro
│   ├── __init__.py
│   ├── __init__.pyc
│   ├── settings.py
│   ├── settings.pyc
│   ├── urls.py
│   ├── urls.pyc
│   ├── wsgi.py
│   └── wsgi.pyc
├── manage.py
├── static
│   └── jason_auth
└── templates
    └── jason_auth
        ├── login_failed.html
        └── login_success.html

2:About parameter.

For example:

I want to pass string 'jason' to my template

in a view function:we use render(a shortcut)

code:

return render(request,'app_name/template_name.html',{'jason':'data'}

##note:

jason is the name that template will receive and recoginze and data is the data you want to pass. It can be an object

3:See the Model function!It is powerful.Come on!

Record the main process:

1:write your home template(contains a form)

in the form you need to add {%csrf_token%} to avoid sctf

if not ,you will receive 403 error

The action is the view you want to handle the request

2:I try to create a view named "login" failed. And struggled for a long time:

Because I import a login model from django, When I want to use the login from django, it will call the login I defined.

So first change the name to login_view in view.py

Next change urls.py views.login to view.login_view

Conclusion: Make sure each view endswith _view. That will be much better

3:

Got a good point: The @ decorator:

For example:

One user want to see a login_required view.

you add @login_required 

::::  

from django.contrib.auth.decorators import login_required

@login_required

def my_view():

    youR busssiness....

4::

user create

#1 Using default user

Code:

from django.contrib.auth.models import User

#return a User 

User.objects.create(username="username",email="test@gmail.com")

5:Custom my User model

TIPS::About UserChangeForm

Class MyUserAdmin(UserAdmin):

    #with it can change user profile

      form = UserChangeForm

      add_form = UserCreationForm

6:

Add static css file

  1:In settings.py   add 

       STATICFILES_DIRS = [os.path.join(BASE_DIR,"static")] 

  2:In a template file add

        {%load staticfiles%}

  3：When you need to use a static  file

       <link rel="stylesheet" type="text/css" href="{%static "loginsys/style.css"%}">
