问题 I want to display ManyToManyField s in admin just like filter_horizontal does, but populate the options as the user types into the filter field. There are many options and loading them all at once takes a lot of time. I found django-ajax-filtered-fields but it seems to me an overkill as it requires changes to model classes, when all I want to do is to replace every multiple select field in a form. Writing a custom widget field that inherits from admin.widgets.FilteredSelectMultiple seems to

问题 I'm using this little jewel of a Django code snippet to edit a ManyToManyField from both directions: class ManyToManyField_NoSyncdb(models.ManyToManyField): def __init__(self, *args, **kwargs): super(ManyToManyField_NoSyncdb, self).__init__(*args, **kwargs) self.creates_table = False class Job(models.Model): persons = ManyToManyField_NoSyncdb( Person, blank=True, db_table='person_jobs' ) (snippet details here) It lets me select all the persons in a given job from the jobs form and inversely

问题 In the change list of the django admin, I want to use list_editable to display a django-autocomplete widget for a ManyToManyField. I found something similar here: list_editable and widgets Normally including a ManyToManyField in list_display raises an ImproperlyConfigured exception, eg: ""'BookAdmin.list_display[2]', 'author' is a ManyToManyField which is not supported." I (perhaps unwisely) removed 3 lines from contrib/admin/validate.py to bypass the exception. :) I now have it spitting out

问题 If I have two Models that have a manytomany relationship with a through model, how do I get data from that 'through' table. class Bike(models.Model): nickname = models.CharField(max_length=40) users = models.ManyToManyField(User, through='bike.BikeUser') The BikeUser class class BikeUser(models.Model): bike = models.ForeignKey(Bike) user = models.ForeignKey(User) comment = models.CharField(max_length=140) And I would add a user to that bike (presuming I have a myBike and a myUser already)

Considering the following models, knowing a family, how do I select Kids with no buyers? class Family... class Kid(models.Model): name = models.CharField(max_length=255) family = models.ForeignKey(Family) buyer = models.ManyToManyField(Buyer, blank=True, null=True) family = get_object_or_404(Family, pk=1) for_sale = family.kid_set.filter(buyer... this screws my child trade business family.kid_set.filter(buyer__isnull=True) should work. Manoj Govindan @piquadrat's answer is correct. You can also do: for_sale = Kid.objects.filter(family__pk = 1, buyer = None) This lets you avoid a separate query
