翻译I've been trying to display a Generic Foreign Key in the Django admin but can't get it working. I have a FullCitation class that can be linked to either a NonSupportedProgram or a SupportedProgram class. So, I have used a generic foreign key.
In the admin, I want users to only be able to select 'NonSupportedProgram' or 'SupportedProgram' from the content_type dropdown and then, from the object_id field, I need users to be able to select from a dropdown listing the existing NonSuportedPrograms or the existing Supported Programs, with the option of creating a new one. Is this possible? Where am I going wrong?
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',)
