g：筛选InlinePanel ForeignKey的结果 [英] Wagtail: Filter results of an InlinePanel ForeignKey

问题描述

这些模型允许我为一个工具建立多个人工编辑器：

These models allow me to establish multiple human "editors" for a tool:

class ToolPageEditors(models.Model):
    person = models.ForeignKey('people.UserProfile')
    page = ParentalKey('ToolPage', related_name='toolpage_editors')


class ToolPage(BaseAsset):
    content_panels = BaseAsset.content_panels + [
        InlinePanel('toolpage_editors', label="Tool Editors")
    ]

但是每个 ToolPageEditors 实例都是一个下拉列表，拥有3,000多个用户。我想将该下拉菜单的内容限制为给定组中的人员。我知道如何通过覆盖admin表单在Django中执行此操作，但是在弄清楚如何在Wagtail中完成操作时遇到了麻烦。

But then each ToolPageEditors instance is a dropdown with more than 3,000 users. I'd like to limit the contents of that dropdown to people in a given group. I know how to do this in Django by overriding the admin form, but am having trouble figuring out how to accomplish it in Wagtail.

建议？谢谢。

更新：

密钥是 limit_choices_to 。对该类进行如下修改，并且可以正常工作：

The key is limit_choices_to. Modified the class as follows and it works:

class ToolPageManagers(models.Model):
    def get_tool_editors():
        g = Group.objects.get(name='Tool Editors')
        return {'groups__in': [g, ]}

    person = models.ForeignKey('people.UserProfile',  limit_choices_to=get_tool_editors)
    page = ParentalKey('ToolPage', related_name='toolpage_editors')

推荐答案

答案是对原始问题的更新，并在下面粘贴了一些文档链接。

您可以通过kwarg limit_choices_to 。

You can limit the available choices on a Django model's foreign key relationship by the kwarg limit_choices_to.

注意：此

将会为关系增加一个限制，而不仅仅是UI中可用的选择。 ode

class ToolPageManagers(models.Model):
    def get_tool_editors():
        g = Group.objects.get(name='Tool Editors')
        return {'groups__in': [g, ]}

    person = models.ForeignKey('people.UserProfile',  limit_choices_to=get_tool_editors)
    page = ParentalKey('ToolPage', related_name='toolpage_editors')
