Django中自带有forms模块，直接使用即可。
例如：
from django import forms
class CommentForm(forms.Form):
user = forms.CharField(label="用户",max_length=10,required=True,widget=forms.TextInput(attrs={"class":"comment","id":"comment"}))
content = forms.CharField(label="内容",required=True,widget=forms.Textarea(attrs={"class":"content"}))
time = forms.DateTimeField(label="提交时间")
第二种
继承ModelForm：根据model生成表单，在实际开发中经常使用。
1、建立model
class Server(models.Model):
name = models.CharField(u"名称", max_length=30, null=True, blank=True, unique=True)
ip = models.IPAddressField(u"IP地址", max_length=20,unique=True)
port = models.IntegerField(u"通信端口")
cpunum = models.IntegerField(u"CPU核数", null=True, blank=True)
mem = models.IntegerField(u"内存", null=True, blank=True)
state = models.CharField(u"状态", max_length=20, null=True, blank=True)
def __unicode__(self):
return self.name
class Meta:
ordering = ['name','ip']
2、建立表单
from django.forms import ModelForm
from .models import Server
cpunum_choice = (
('', u"---------"),
(2, u"2"),
(4, u"4"),
(8, u"8"),
(16, u"16"),
)
class ServerForm(ModelForm):
#修改属性
cpunum = forms.ChoiceField(label=_(u"CPU核数"),required=True, choices=cpunum_choice)
class Meta:
model = Server
#限定属性
fields = ('name', 'ip', 'prot', 'cpunum', 'mem')
此方法也可以自定义css
如下：
class UserForm(forms.ModelForm):
class Meta:
model = User
fields = ['username','password']
widgets = {
'username': forms.TextInput(attrs={'class': 'form-control','placeholder':'用户名',}),
'password': forms.TextInput(attrs={'class': 'form-control','placeholder':'密码',}),
}
修改表单项
level_choice = (
('ext', u"特急"),
('ugt', u"紧急"),
('nor', u"普通"),
)
class ServerForm(ModelForm):
level = forms.ChoiceField(label=_(u"任务等级"),required=True, widget=forms.RadioSelect, choices=level_choice)
class Meta:
model = Server
fields = ('name', 'ip', 'prot', 'cpunum', 'mem')
