作用：验证+（生成HTML+保存上次提交的数据）

         使用：

             1、创建类

             2、创建字段（）

             3、验证用户输入：

                 obj=Form(request.POST,request.FILES)

                     if obj.is_valid():

                         obj.cleaned_data

                     else:

                         obj.errors

             4、clean_字段

             5、clean()  _post_clean()

             PS:__all__ 整体错误信息

1.form类的运行顺序是init，clean，validte，save
其中clean和validate会在form.is_valid()方法中被先后调用。(这里留有一个疑问，结构完全相同的两个form，但是一个为先验证后clean，另一个先clean后验证。原因不明。)
这里https://docs.djangoproject.com/en/dev/ref/forms/validation/给的是先验证后clean
2.cleaned_data中的值类型与字段定义的Field类型一致。
如果字段定义charfield，那么clean方法返回的cleaned_data中对应的字段值就是字符型，
定义为ModelChoiceField，则cleaned_data中字段值是某个model实例。
定义为ModelMultipleChoiceField，则cleaned_data中字段值是个model实例list。
3.clean等步骤遇到的异常：Exception Value: argument of type 'NoneType' is not iterable.
可能是cleaned_data中某个字段值应该是个列表，实际上却是空值。
4.ModelForm的Meta类中定义的fields
默认的Field是Model中定义的Field，如需更改，可在Form类内以同名字段覆盖，比如自定义widget和required属性等。
不管字段在form中怎么自定义，cleaned_data中对应的值都必须按照model中定义的字段类型取值，否则校验不通过或保存时报错。
暂时记这几条，form还可以重写init、save方法，并且可以自定义方法。如果对这几个东西不懂，想办法找例子读一遍就懂了。
※※※ clean方法重写时一定不要忘了return cleaned_data ※※※
补充：
5.form的四种初始化方式
①实例化oneform(initial={'onefield':value})
②定义字段时给初始化值oneformfield = forms.CharField(initial=value)
③重写Form类的__init__()方法：self.fields['onefield'].initial = value
④当给form传参instanse(即oneform(instanse=onemodel_instance))时，前三种初始化方法会全部失效，即使重写__init__时，先调用父类的__init__再使用方法③，仍然无效(不是很爽)。
这时想重新初始化字段值只能在__init__()里 self.initial['title'] = value，直接对Form类的initial属性字典赋值。
