django - 如何在管理内联中用实际对象的字段替换 content_type 和 object_id 字段？

Question

我有内联，它显示了 contenttype 模型的数据，所以我看到的不是真实对象，而是 content_type 和 object_id 字段。我可以排除这些字段 - 这不是问题，但我也想在下拉列表中使用另一个 Places 获得真实对象作为 selected .谁能告诉我，我该怎么做？

型号:

class Criterias(models.Model):
    name = ...

class Places(models.Model):
    name = ...

class PlacesToCriterias(models.Model):
    content_type = models.ForeignKey(ContentType, on_delete=models.CASCADE)
    object_id = models.PositiveIntegerField()
    content_object = GenericForeignKey()

    criteria_group = models.ForeignKey(Criterias)

管理员:

class CriteriaPlacesInlineAdmin(admin.TabularInline):
    model = PlacesToCriterias

class CriteriasAdmin(admin.ModelAdmin):
    inlines = [CriteriaPlacesInlineAdmin]

admin.site.register(Criterias, CriteriasAdmin)

我可以向 CriteriaPlacesInlineAdmin 添加一个 form，例如:

class CriteriaPlacesChoicesFieldForm(forms.ModelForm):
    places = forms.ModelChoiceField(PlaceTypesGroups.objects.all(), label='place')

但是我如何将\add object_id 传递到这个表单\query 以便在下拉列表中获得“选定”位置？

Answer 1

找到解决方案。

将表单添加到 admin.TabularInline:

class CriteriaPlacesInlineAdmin(admin.TabularInline):
    model = PlacesToCriterias
    form = CriteriaPlacesChoicesFieldForm  # <- ADDED FORM

class CriteriasAdmin(admin.ModelAdmin):
    inlines = [CriteriaPlacesInlineAdmin]

admin.site.register(Criterias, CriteriasAdmin)

表格:

class CriteriaPlacesChoicesFieldForm(forms.ModelForm):
    ct_place_type = ContentType.objects.get_for_model(PlaceTypesGroups)

    object_id = forms.ModelChoiceField(PlaceTypesGroups.objects.all(), label='places')
    content_type = forms.ModelChoiceField(ContentType.objects.all(), initial=ct_place_type, widget=forms.HiddenInput())

    def clean_object_id(self):
        return self.cleaned_data['object_id'].pk

    def clean_content_type(self):
        return self.ct_place_type
