问题描述

我有一个设置页面，用户可以选择是否要接收通讯。

I've a settings page where users can select if they want to receive a newsletter or not.

我想要一个复选框，我想要Django如果newsletter在数据库中为true，请选择它。如何在Django中实现？

I want a checkbox for this, and I want that Django select it if 'newsletter' is true in database. How can I implement in Django?

推荐答案

models.py

class Settings(model.Model):
    receive_newsletter = model.BooleanField()
    ...

forms.py

class SettingsForm(forms.ModelForm):
    receive_newsletter = forms.BooleanField()

    class Meta:
        model = Settings

如果要根据您的应用程序中的某些条件自动将receive_newsletter设置为True，请在表单中介绍 __ init __

If you want to automatically set receive_newsletter to True according to some criteria in you application you account for that in the forms __init__

forms.py

class SettingsForm(forms.ModelForm):

    receive_newsletter = forms.BooleanField()

    def __init__(self):
        if check_something():
            self.fields['receive_newsletter'].initial  = True

    class Meta:
        model = Settings

布尔表单字段默认使用CheckboxInput小部件。

The boolean form field uses a CheckboxInput widget by default.
