Introduce element-ui
vscode syntax tips
Vscode-element-helper If you use the element-ui library, you can install this plug-in and automatically prompt el when writing tags.
Official introduction tutorial: Element - The world's most popular Vue UI framework
import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';
Vue.use(ElementUI);
Method 2: Create a command line window and introduce axios and element-ui:
Note: Enter the front-end storage directory and run: vue create vue-admin Note: If the creation is unsuccessful, please run the idea as an administrator
npm install --save axios vue-axios
Write some code in main.js
import axios from 'axios'
Vue.prototype.axios = axios
The username and password submitted to the backend by the vue front-end post cannot be obtained by django using request.POST.get("username")
The solution is found because the submitted parameters are json, so we need to use the qs tool class to convert them.
Solution:
1) Use cmd to open the vue project directory and install the qs modulenmp install qs --save(2) Open main.js and quote qs
//引入qs import qs from 'qs'; Vue.prototype.qs = qs;import qs from 'qs';
qs.stringify(this.loginForm)
login() {
this.$refs.loginFormRef.validate(async valid => {
if (!valid) return;
const result = await this.$http.post("login2/", qs.stringify(this.loginForm));
console.log(result)
});
}
npm i element-ui -S
main.js introduction and use
import ElementUI from 'element-ui'
import 'element-ui/lib/theme-chalk/index.css'
Vue.use(ElementUI)
vue add element
cd to the vue-admin root directory and run npm run serve after the creation is complete

问题：Command vue init requires a global addon to be installed. Please run npm i -g @vue/cli-init and
The solution is to run cmd administrator:
Today, when I installed vue-cli globally , the above problem suddenly occurred:
The reason is because the command vue init needs to install a global add-on.
Enter the command directly: npm install -g @vue/cli-init
I use vue create first-demo and press Enter to select the third item
For method 2, please refer to the following: vue init webpack projectname

Django configuration swagger
Reference tutorial: Django project uses Swagger to automatically generate API documents - Jianshu
Django projects use Swagger to automatically generate API documentation
Introduction
After the interface development is completed, the next step is to write the interface document. Traditional interface documentation is written using Word or some other interface document management platform. It is troublesome to maintain and update interface documents in this form. Every time there is a change in the interface, the document must be modified manually.
Swagger is a very useful tool for managing Api documents. Not only does the Spring series have a toolkit for automatically generating Swagger Api documents, but Python also has one (the configuration is very, very simple)!
Django is connected to Swagger. When introducing the method of connecting Django to Swagger, many materials on the Internet are based on the django-rest-swagger library. As everyone knows, starting from June 2019, the official has abandoned this library. In django 3.0 This library is no longer supported and is replaced by a new third-party drf-yasg library.
use
1.Installation
Install drf-yasg library
pip install drf-yasg2. Edit the settings file
Modify the project settings.py file and add api and drf_yasg.
INSTALLED_APPS = [ ... 'drf_yasg', ]
3.Routing settings
Edit the url.py file
# Configure various parameters of swagger from drf_yasg import openapi from drf_yasg.views import get_schema_view schema_view = get_schema_view( openapi.Info( title="XX project API", # name default_version="version v1.0.0", # version description="XX project API interaction documents are automatically generated by Swagger", # Project description ), public=True, ) urlpatterns = [ # These two url configurations must be present, used to generate the UI interface, other urls can be defined normally just path(' swagger/', schema_view.with_ui('swagger', cache_timeout=0), name='schema-swagger-ui'), path( 'redoc/', schema_view.with_ui('redoc', cache_timeout=0), name= 'schema-redoc'), ]
\1. Create a middlewares.py file under the app and write the following code:
from django.utils.deprecation import MiddlewareMixin class MyTest(MiddlewareMixin): def process_response(self, request, response): response['Access-Control-Allow-Origin'] = "*" return response\2. Register the middleware you just wrote in setting.py:
MIDDLEWARE = [ ... ... 'apidemo.middlewares.MyTest', ]
4. Test access
Access after restarting the project

Install vue-element-admin
# Clone the project git clone https://github.com/PanJiaChen/vue-element-admin.git # Enter the project directory cd vue-element-admin # Install dependencies npm install # It is recommended not to use cnpm as there are various installation issues The weird bug can be solved by the following operations: npm install --registry=https://registry.npmmirror.com # Local development startup project npm run devvueAdmin-template is a set of background management system basic templates (at least streamlined version) based on vue-element-admin, which can be used as a template for secondary development.
GitHub address: https://github.com/PanJiaChen/vue-admin-template
Suggestion: You can carry out secondary development based on vue-admin-template, use vue-element-admin as a toolbox, and copy whatever functions or components you want from vue-element-admin.
When using npm install to install dependencies, an error occurs npm ERR! Error while executing

Analysis and solutions for npm install failure, as well as the repaired code address [An effective solution verified by 2000+ people]
To-do
Built in
2022-02-22 14:17
The reason for this failure is due to the rename of tui-editor (rich text editor plug-in), which has now been renamed toast-ui/editor (the first step below) and the plug-in has also renamed its file name (the second step below) And rename the method name (the third step below)
The solution is as follows: 1. First modify the tui-editor line in package.json to "@toast-ui/editor": "^3.1.3",
2. Enter the \src\components\MarkdownEditor\index.vue file, delete all its imports and replace them with the following four lines import 'codemirror/lib/codemirror.css' import '@toast-ui/editor/dist/toastui-editor .css' import Editor from '@toast-ui/editor' import defaultOptions from './default-options'
3. Replace the getValue and setValue of the page (still the file in the second article) with getMarkdown and setMarkdown respectively. Replace all tui-editors in the page with @toast-ui/editor.
4. Save the file and npm install is done.
Or you can directly go to this address to clone the project file I repaired: vue-element-admin-fix-install-problem: Let me make a small advertisement: My domain name vue4.com is on sale in Alibaba Cloud. Clone it and just npm install it, and it will work normally. Started, corresponding to the master branch of Brother Pant. This library is only for temporary use by brothers who are troubled by the installation failure. I will delete it after Brother Pant repairs his own library.

To download Redis-x64-5.0.14.1.zip , it is recommended to use Thunder download
Redis installation + set password
1. Download the Redis installation package and unzip it.
2. Open a cmd window and use the cd command to switch directories to C:\redis and run:
redis-server.exe redis.windows.conf
At this time, open another cmd window. Do not close the original one, otherwise you will not be able to access the server.
redis-cli.exe -h 127.0.0.1 -p 6379
3. The client uses the config get requirepass command to check the password.
config get requirepass
1
1)“requirepass”
2)"" //default empty
4. The client uses the config set requirepass yourpassword command to set the password.
config set requirepass 123456
1
5. Once a password is set, it must be verified first, otherwise all operations will be unavailable.
config get requirepass
1
(error)NOAUTH Authentication required
6. Use auth password to verify password
auth 123456
OK
config get requirepass
1 2 3
1)“requirepass”
2)“123456”
7. Log out and log in again
redis-cli.exe -h 127.0.0.1 -p 6379 -a 123456
