Django之Form的ModelForm

form与model的终极结合。

from django import forms

class BookForm(forms.ModelForm):

    class Meta:
        model = models.Book
        fields = "__all__"
        labels = {
            "title": "书名",
            "price": "价格"
        }
        widgets = {
            "password": forms.widgets.PasswordInput(attrs={"class": "c1"}),
        }

class Meta:下常用参数：

model = models.Student  # 对应的Model中的类
fields = "__all__"  # 字段，如果是__all__,就是表示列出所有的字段
exclude = None  # 排除的字段
labels = None  # 提示信息
help_texts = None  # 帮助提示信息
widgets = None  # 自定义插件
error_messages = None  # 自定义错误信息
