Note: I started to contact the python programming language. On the first day of self-learning project framework construction, I used the current mainstream framework Django to build web projects.
Preliminary preparations:
python 3.7
Django 2.2
Pycharm
mysql
navicat
- Since I have a programming foundation, I am a Java development engineer, so I do n’t have much record of the installation process of the basic software. The current environment configuration only explains Django.
Installation of Django 2.2 environment
Open the cmd window, first make sure that the computer has python installed, and the environment has been configured well, then perform the following
pip install django==2.2 -i https://pypi.doubanio.com/simple
Note: The above command refers to the version of Django2.2 installed, the address is the domestic mirror address, the download is smooth, and the
installation will be successful:
Successfully installed django-2.2
You can also use the following command to view the current version of Django installed on the system
pip show django
Pycharm initial project creation
1.Pycharm If the community version is installed, there is no option below, the professional version refers to the operation below
1. Select Django option
2. Open Project Interpreter: Python 3.7-Existing interpreter-find the python launcher under the file directory of your python installation in Interpreter, which is python.exe
3. Fill in the name of the module in Application name, Click Create. The
initial structure has been successfully created, and then create some folders to get the general framework of Django. The
general framework is as follows:
New folder description:
1. static: static file resource directory, used to store css, js, html, etc.
2. media: a directory used to store resources such as pictures and videos uploaded and downloaded by the system
3. apps: create a package directory and place the original project package below to facilitate project management
4. extra_apps: create a package directory, It is convenient to place the source code of the third party under this directory.
5. requirements.txt: Create a requirements.txt file to record which packages the project depends on and the version of the project package
