Python study note 23: Django builds a simple blog website (1), pythondjango
The previous section describes how to download and install Django. This section describes how to use Django to create and run a website.
1. Create a project command:
Django-admin startproject mysite
# Some need to enter:
Django-admin.py startproject mysite
You will find that a folder mysite is generated under the current directory, and its structure is:
Mysite/
Manage. py
Mysite/
_ Init. py
Settings. py
Urls. py
Wsgi. py
Where:
Manage. py: a command line tool that can call Django shell and database. Type python manage. py-h to view its functions.
_ Init _. py: Let Python treat this directory as a file required by an Development Kit (that is, a group of modules. This is an empty file. You do not need to modify it.
Settings. py: the default settings of the project, including the database information, debugging flag, and other working variables.
Urls. py: Set the URL of the django project. It can be viewed as the directory of your django website and is responsible for ing the URL mode to the application.
Wsgi. py: A simple and common Interface between a Web Server and a web service program or framework.
2. Run the following command in the mysite Directory: python manager. py runserver
If an error occurs:
XXX
You have unapplied migrations; your app may not work properly until they are applied. Run 'python manage. py migrate' to apply them.
XXX
Obviously, we have already told you how to do this. Execute python manage. py migrate.
What does migrate do? It allows us to reconstruct the table structure without affecting the existing data after modifying the Model.
The following output is displayed:
Operations to perform:
Apply all migrations: admin, contenttypes, auth, sessions
Running migrations:
Applying contenttypes.0001 _ initial... OK
Applying auth.0001 _ initial... OK
Applying admin.0001 _ initial... OK
Applying sessions.0001 _ initial... OK
You will find that the file dg. sqlite3 is added to the mysite directory on the previous layer.
(Or Add the following sentence in settings. py:
TEST_RUNNER = 'django. test. runner. DiscoverRunner')
Then run the server again, with the following output:
System check identified no issues (0 silenced ).
