Python database programming: Django reads Mysql data and displays it on the front end

Today I will share with you an example of Django reading Mysql data and displaying it on the front end. It has a good reference value and I hope it will be helpful to you. Let's follow the editor to take a look
Preface:

Since the Django framework is used to build a website, it needs to dynamically display the information in the database, so it is necessary to read the database and write this blog post to record.

The next two steps to do this, add web pages, read the database;

1. Add a web page

First, add a webpage according to the steps of adding a webpage, my webpage is named table.html, and the app is named web;

Place table.html in the corresponding directory;

The forms.py file is written in advance;

Modify views.py to make a good view

from django.shortcuts import render
from web import forms
def table(request):
  table_form=forms.SignupForm()
  return render(request,'table.html',{'form':table_form}
  )

Modify url.py, add path

from django.conf.urls import url,include
from django.contrib import admin
from web import views
urlpatterns = [
  url(r'^signup/$',views.signup,name='signup'),
  url(r'^index/$',views.index,name='index'),
  url(r'^table/$',views.table,name='table') #This is table
]

This can be accessed

Display web content normally.

Two, read Mysql and display

Create the database Employee in models.py and set the name column (the default will have an id column as the primary key);

from __future__ import unicode_literals
from django.db import models
# Create your models here.
class Employee(models.Model):
   name=models.CharField(max_length=20)

Save and synchronize the database

python manage.py syncdb

Then enter mysql, find the database set by our django, enter it,

See the following table
Figure 1 Database table entry

The last web_employee is the table we just created (web is the name of my app, and the prefix is automatically added);

Use the insert statement to insert the corresponding data, as shown below:
Figure 2 employee table

The ok data has been added, and the next step is to display it on the web page. The web page can be displayed normally through the previous configuration. Now add the display database information.

First modify the views.py, the same, the modification of the view is in this file

 from django.shortcuts import render
from web import forms
from models import Employee    #Insert employee table
from django.shortcuts import HttpResponseRedirect,Http404,HttpResponse,render_to_response
# Create your views here.
def table(request):
  table_form=forms.SignupForm()  #Style, configured in forms.py
  names=Employee.objects.all()  #Get our database information into names
  #return render(request,'table.html',{'form':table_form})
  return render_to_response("table.html",locals()) #Must use this return

The variable names read our data, and then go to table.html

<html lang="en">
  <head>
    <meta charset="UTF-8">
    <title>Upload Successfully</title>
  </head>
  <body>
    <p>Student list</p>
    {% for name in names %}
    <p>{{name.id}}   :   {{name.name}}</p>
    <br>
    {% endfor %}
  </body>
</html>

Use a loop to read the information in names, name.id and name.name are two columns in our table, as shown in Figure 2 above.

The final result is as follows:
