新定义的表单django.forms.ModelForm--做为客户端的控制
管理模块django.admin.ModelAdmin --做为服务端的控制
在models.py中我有如下的数据库Blog
#coding: utf-8
from django.db import models
# Create your models here.
class Blog(models.Model):
caption = models.CharField(max_length=200,verbose_name=u"标题")
content = models.TextField(verbose_name="内容")
visit = models.IntegerField(verbose_name=u"访客")
weight = models.IntegerField(verbose_name=u"权重")
date = models.DateField(auto_now=True, verbose_name=u"更新时间")
class Meta:
verbose_name = u"文章"
def __unicode__(self):
return '%s %s'%(self.caption,self.date)
对应的默认后台管理表单
如果要修改客户端显示，即主要修改forms.ModelForm,主要的几个属性就是widget、CharField等
class BlogForm(forms.ModelForm):
content = forms.CharField(initial='like oldrss',widget=forms.Textarea(attrs={'class':'vLargeTextField'}))
image = forms.ImageField()
visit = forms.CharField(initial=0,widget=forms.TextInput(attrs={'readonly':'true'}))
uid = forms.CharField(initial=0, widget=forms.TextInput(attrs={'readonly':'true'}))
class Meta:
forms.model = Blog
forms的属性可以这样查看
>>> dir(django.forms)

修改表单显示
from django import forms
class BlogForm(forms.ModelForm):
content = forms.CharField(initial='like oldrss',widget=forms.Textarea(attrs={'class':'vLargeTextField'}))
image = forms.ImageField()
visit = forms.CharField(initial=0,widget=forms.TextInput(attrs={'readonly':'true'}))
uid = forms.CharField(initial=0, widget=forms.TextInput(attrs={'readonly':'true'}))
class Meta:
forms.model = Blog
其中initial初始化表单的值，相当于value的值。widget后面的参数attrs是属性设置。
控制表单的显示
class BlogAdmin(admin.ModelAdmin):
list_display = ('caption','uid','date')#modify display
search_fields = ('caption','uid')#add search
list_filter = ('date',)
date_hierarchy = 'date'
form = BlogForm
fields = ('caption','content','visit','weight')
list_display 是ModelAdmin的一个属性，控制显示以上几个字段，searc_fields 控制显示一个搜索框，list_filter控制date为过滤选项等等。fields控制表单只显示如上的几个属性。
以上即可以实现修改一个表单。一份较为完整的代码如下。
from django.contrib import admin
from models import *
from django import forms
class BlogForm(forms.ModelForm):
content = forms.CharField(initial='like oldrss',widget=forms.Textarea(attrs={'class':'vLargeTextField'}))
image = forms.ImageField()
visit = forms.CharField(initial=0,widget=forms.TextInput(attrs={'readonly':'true'}))
uid = forms.CharField(initial=0, widget=forms.TextInput(attrs={'readonly':'true'}))
class Meta:
forms.model = Blog
class BlogAdmin(admin.ModelAdmin):
list_display = ('caption','uid','date')#modify display
search_fields = ('caption','uid')#add search
list_filter = ('date',)
date_hierarchy = 'date'
form = BlogForm
fields = ('caption','content','visit','weight')
# Register your models here.
admin.site.register(Blog,BlogAdmin)
