Django 管理中的泛型关系/泛型外键

Question

我一直在尝试在 Django 管理中显示GenericForeignKey，但无法让它工作。我有一个可以链接到NonSupportedProgram或SupportedProgram类的FullCitation类。因此，我使用了通用外键。

在管理员中，我希望用户只能从content_type下拉列表中选择'NonSupportedProgram'或'SupportedProgram'，然后，从object_id字段中，我需要用户能够从列出现有NonSuportedProgram或现有SupportedProgram的下拉列表中选择，并可以选择创建新。这可能吗？我哪里出错了？

models.py

class FullCitation(models.Model)
    # the software to which this citation belongs
    # either a supported software program or a non-supported software program
    limit = models.Q(app_label = 'myprograms', model = 'supportedprogram') | models.Q(app_label = 'myprograms', model = 'nonsupportedprogram') 
    content_type = models.ForeignKey(ContentType), limit_choices_to = limit, )
    object_id = models.PositiveIntegerField()
    content_object = generic.GenericForeignKey('content_type', 'object_id')
    is_primary = models.BooleanField(help_text="Is this the Primary Citation for the software program?")
    class Meta:
        unique_together = ('content_type', 'object_id')
        app_label = 'myprograms'
reversion.register(FullCitation)
class NonSupportedProgram(models.Model):
    title = models.CharField(max_length=256, blank = True)
    full_citation = generic.GenericRelation('FullCitation')
    class Meta:
        app_label = 'myprograms'
reversion.register(NonSBGridProgram)
class SupportedProgram(models.Model):
    title = models.CharField(max_length=256, blank = True)
    full_citation = generic.GenericRelation('FullCitation')
    # and a bunch of other fields.....

admin.py

class FullCitationAdmin(reversion.VersionAdmin):
    fieldsets = (
    ('Which Program', { 
        'fields': ('content_type', 'object_id', ),
    }),
    ('Citation Information', {
        'fields': ('is_primary',),
    }),)
# autocomplete_lookup_fields = {
#     'generic': [['content_type', 'object_id']],
#     } 
# inlines = ['NonSupportedProgramInline', ]
list_display = ('content_object', 'is_primary',)
search_fields = ('content_object__title', )
# list_filter = ('content_object',)

这是一个在 Django Admin 中渲染 GenericForeignKeys 的模块：

它只是不适用于没有冲突的jQuery设置(如来自Django CMS的设置(。
