django model form 关联

参考：

(1)、字段类型的对应，django model的字段类型对应到form的字段类型，这里列举一下几个重要的：

 

Model field	Form field
BooleanField	BooleanField
CharField	CharField with max_length
DateField	DateField
DateTimeField	DateTimeField
FileField	FileField
ForeignKey	ModelChoiceField
IntegerField	IntegerField
ManyToManyField	ModelMultipleChoiceField
TextField	CharField with widget=forms.Textarea

• ForeignKey is represented by django.forms.ModelChoiceField, which is a ChoiceField whose choices are a model QuerySet.
• ManyToManyField is represented by django.forms.ModelMultipleChoiceField, which is a MultipleChoiceField whose choices are a model QuerySet.

 

(2)、对应的属性

如果model 字段 有blank=True, 则表单类中对应的要 required=False,否则required=True

表单字段的 label 被设置为model field的 verbose_name  且第一个字符大写.

表单字段的 help_text 对应models field的 help_text

如果model 字段有choices 则表单字段widget 设置 Select
