Django之CURD

创建[app名称]模块

python manage.py startapp [app名称]

添加到项目settings.py的INSTALL_APPS中

# mysite/settings.py
INSTALLED_APPS = [
     'django.contrib.admin',
     'django.contrib.auth',
     'django.contrib.contenttypes',
     'django.contrib.sessions',
     'django.contrib.messages',
     'django.contrib.staticfiles',
     '[app名称]',
 ]

然后把[app名称]下的路由添加到项目的urls.py中取

 from django.contrib import admin
 from django.urls import path, include

 urlpatterns = [
     path('admin/', admin.site.urls),
     path('tasks/', include('tasks.urls'))
 ]

创建[app名称]模型及其关联表单

模型很简单 仅包含name和status两个字段 我们还使用ModelForm类创建了XxxForm 在创建或者更新的时候要用到这个表单

# tasks/models.py
 from django.db import models

 class Status(models.TextChoices):
     UNSTARTED = 'u', "Not started yet"
     ONGOING = 'o', "Ongoing"
     FINISHED = 'f', "Finished"


 class Animals(models.Model):
     name = models.CharField(verbose_name="Task name", max_length=65, unique=True)
     status = models.CharField(verbose_name="Task status", max_length=1, choices=Status.choices)

     def __str__(self):
         return self.name

 # tasks/forms.py
 from .models import Task
 from django import forms

 class AnimalsForm(forms.ModelForm):

     class Meta:
         model = Task
         fields = "__all__"
