在Django管理员更改列表中的ManyToManyField小部件？ [英] ManyToManyField widget in a django admin change list?

问题描述

在django管理员的更改列表中，我想使用list_editable为ManyToManyField显示一个django-autocomplete小部件。

In the change list of the django admin, I want to use list_editable to display a django-autocomplete widget for a ManyToManyField.

我在这里找到类似的内容：一个href =https://stackoverflow.com/questions/7065982/list-editable-and-widgets> list_editable和小部件

I found something similar here: list_editable and widgets

通常包括一个list_display中的ManyToManyField引发了一个不正确的配置异常，例如：

Normally including a ManyToManyField in list_display raises an ImproperlyConfigured exception, eg:

BookAdmin.list_display [2]'，'author'是一个ManyToManyField不支持。

""'BookAdmin.list_display[2]', 'author' is a ManyToManyField which is not supported."

我（可能不明智地）从contrib / admin / validate.py中删除了3行以绕过该异常。 ）

I (perhaps unwisely) removed 3 lines from contrib/admin/validate.py to bypass the exception. :)

我现在已经把它分开了，这是接近（？）但没有雪茄。

I now have it spitting out the following, which is close(?) but no cigar.

< django.db.models.fields.related.ManyRelatedManager对象在0x1032a85d0>

<django.db.models.fields.related.ManyRelatedManager object at 0x1032a85d0>

任何想法有没有更好的方法？

Any thoughts on how to proceed? Is there a better way of doing this?

这是我现在所在的：（AuthorAutocomplete在常规管理表单中正常工作）

Here's what I have at the moment: (AuthorAutocomplete is working fine in the regular admin form)

class AuthorAutocomplete(AutocompleteSettings):
    search_fields = ('first_name', 'last_name')

class BookAdmin(AutocompleteAdmin, admin.ModelAdmin):
    def get_changelist_form(self, request, **kwargs):
      kwargs.setdefault('form', AuthorAutocompleteForm)
      return super(BookAdmin, self).get_changelist_form(request, **kwargs)    
      list_display = ['isbn', 'title', 'author', 'publisher']
      #...

class AuthorAutocompleteForm(forms.ModelForm):
    class Meta:
        model  = Book
    author = AuthorAutocomplete

谢谢！

推荐答案

这是一个旧主题，但我希望这可能有助于别人。

This is an old topic, but I'm hoping this might help someone else.

要获取ManyToMany字段的值，您可以显示其值，您可以执行以下操作。我使用list_display作为一个例子。

To get the values for a ManyToMany field so you can display their values you can do the follow. I'm using list_display as an example.

class TestAdmin(admin.ModelAdmin):
    def get_some_value(self):
        return ", " . join([x.__str__() for x in self.manytomany_field.all()])

    list_display(get_some_value)
    get_some_value.short_description = 'Title' #sets column header to Title
