在django中内置了form类和model类，当页面中的form值和model字段值完全一样时，此时可以通过model生成一个完全一样的form，Django中的modelForm就因此而生。
目标：
定义Author表，通过modelform提交数据到数据库
创建工程及app
python django-admin.py startproject formstudy cd formstudy python manager.py startapp study
编辑models.py
from __future__ import unicode_literals
from django.db import models
# Create your models here.
TITLE_CHOICES = (
(‘MR‘,‘Mr.‘),
(‘MRS‘,‘Mrs.‘),
(‘MS‘,‘Ms.‘),
)
class Author(models.Model):
name = models.CharField(max_length=100)
title = models.CharField(max_length=3,choices=TITLE_CHOICES)
birth_date = models.DateField(blank=True,null=True)
def __unicode__(self):
return self.name
class Book(models.Model):
name = models.CharField(max_length=100)
authors = models.ManyToManyField(Author)
在app目录下新建forms.py
修改views.py
修改urls.py
urlpatterns = [
url(r‘^admin/‘, admin.site.urls),
url(r‘^testModelform/$‘, views.testModelForm, name=‘testModelForm‘),
]
在templates目录下创建testModelForm.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Mode测试</title>
</head>
<body>
<form method="post" action=".">{% csrf_token %}
<table>
<tr>
<td>
<label for="id_name">作者名:</label>
</td>
<td>
{{ form_info.name }}
</td>
<td>
{{ form_info.name.errors }}
</td>
</tr>
<tr>
<td>
<label for="id_title">标题:</label>
</td>
<td>
{{ form_info.title }}
</td>
<td>
{{ form_info.title.errors }}
</td>
</tr>
<tr>
<td>
<label for="id_title">出生日期:</label>
</td>
<td>
{{ form_info.birth_date }}
</td>
<td>
{{ form_info.birth_date.errors }}
</td>
</tr>
<tr>
<td>
<input type="submit" value="注册">
</td>
<td>
<input type="reset" value="重置">
</td>
</tr>
</table>
</form>
</body>
</html>
修改admin.py
from django.contrib import admin
import models
# Register your models here.
class AuthorAdmin(admin.ModelAdmin):
list_display = [‘name‘,‘title‘,‘birth_date‘]
admin.site.register(models.Author)
修改settings.py
INSTALLED_APPS = [
‘django.contrib.admin‘,
‘django.contrib.auth‘,
‘django.contrib.contenttypes‘,
‘django.contrib.sessions‘,
‘django.contrib.messages‘,
‘django.contrib.staticfiles‘,
‘study‘,
]
启动服务
python manage.py runserver 127.0.0.1:8001
效果图
此时可以通过表单提交数据到数据库了
