Django通过CheckboxSelectMultiple窗口小部件选择groupby [英] Django form choices groupby with CheckboxSelectMultiple widget

问题描述

更新：看起来我必须创建自定义窗口小部件（在Django中分组复选框选择多个选项）。在完成后会包括最终的代码。

UPDATE: Looks like I will have to create custom widget (Grouping CheckboxSelectMultiple Options in Django). Will include the final code when I'm done.

我已经设置了一个django形式的选项字段，类似于另一个 SO问题。

I have set up a choice field in a django form similar to another SO question.

但是，我想使它成为一个 CheckboxSelectMultiple 窗口小部件，但是在类Meta中创建整个组的复选框。这是我需要在 __ init __ 中执行的操作，如果是这样？

However, I would like to make it a CheckboxSelectMultiple widget, but doing so in the class Meta creates a checkbox for the entire group. Is this something I need to do in the __init__, if so how?

class FooIterator(models.ModelChoiceIterator):
    def __init__(self, *args, **kwargs):
        super(models.ModelChoiceIterator, self).__init__(*args, **kwargs)
    def __iter__(self):
        for thing in MyModel.objects.all():
            yield (thing.name, [(x.id, x.name) for x in MyModel2.objects.filter(name=thing.name)])

class MyForm(ModelForm):
    def __init__(self, *args, **kwargs):
        super(MyForm, self).__init__(*args, **kwargs)
        self.fields['myField'].choices = FooIterator()
        for x in self.fields:
            self.fields[x].widget.attrs['class'] = 'input-block-level'

推荐答案

看起来像创建自定义小部件是要走的路径 - 根据分组复选框在Django中选择多个选项

Looks like creating a custom widget was the way to go - as per Grouping CheckboxSelectMultiple Options in Django

注意：我按照如何在Django Select窗口小部件中分组？
