Comment (by Emmanuel Katchy):

 For clarity and to help whoever might take this up in the future:

 This is still an issue in Django ''5.2.dev20240621100134''.

 Given the following models


 {{{
 from django.db import models


 class Student(models.Model):
 name = models.CharField(max_length=50)
 age = models.PositiveIntegerField()

 def __str__(self) -> str:
 return self.name


 class Course(models.Model):
 name = models.CharField(max_length=20)
 students = models.ManyToManyField(
 to=Student,
 related_name="courses",
 related_query_name="course",
 )

 def __str__(self) -> str:
 return self.name

 }}}

 and the admin.py
 {{{
 from django.contrib import admin
 from django.contrib.admin import ModelAdmin

 from core.models import Course, Student


 @admin.register(Course)
 class CourseAdmin(ModelAdmin): ...


 @admin.register(Student)
 class StudentAdmin(ModelAdmin):
 filter_horizontal = [
 "course",
 ]

 }}}


 It raises an error
 {{{
 ERRORS:
 : (admin.E020) The value of
 'filter_horizontal[0]' must be a many-to-many field.
 }}}


 This error is raised by
 **django.contrib.admin.checks.BaseModelAdminChecks._check_filter_item**.

 However, getting the widget to render would require modifying
 **ModelAdmin.get_form** as well.

New description:

 Allow manytomany relationships to be defined both ways
 E.G

 {{{
 class ItemType(meta.Model):
 name = meta.CharField(maxlength=100)
 descritpion = meta.CharField(maxlength=250)

 class PropertyType(meta.Model):
 name = meta.CharField(maxlength=100)
 itemtypes = meta.ManyToManyField(ItemType)
 }}}

 Excellent. When I make a new property type in the admin screen I get a
 multiselect window for item types.

 What I want to be able to do however is have this work back the other
 way too so that when I create a new item I can specify what property
 types apply.

 Thanks

 The form approach does not work correctly because in the history view of
 the model in admin there are no entries for changed reverse M2M fields.

 This snippet provides a workaround for this: https://snipt.net/chrisdpratt
 /symmetrical-manytomany-filter-horizontal-in-django-admin/
 (and does it at the form level instead of with models)

Comment (by collinanderson):

 Awesome. As some have mentioned, I think the next basic step make auto
 created reverse related fields (especially ManyToManyRel) into actual
 fields.

 After that, we'd need to allow ManyToManyRel to be used in any model form.

 Here's what I think would be a start. (Doesn't work at all)

 The new _meta options api has landed. I'm very interested in seeing this

 work with a little bit of direction. (Not sure where the best place to
 post that kind of query).

Comment (by Koen Biermans ):

 This seems to be more or less the same as #10964. I have a more generic
 solution for it on that ticket that allows you to use the reverse
 descriptor for M2M or nullable FK (like 'book_set') in the fields set for
 any modelform. It is also available in admin (also for filter_horizontal
 and filter_vertical).

 Should one of these be considered as a duplicate?

Comment (by kux):

 For people who still bump into this, it might be worth checking
 https://github.com/kux/django-admin-extend

 It provides a mechanism for injecting bidirectional many-to-many fields in
 ModelAdmins that have already been defined by other apps.

Comment (by rhunwicks):

 Using Django 1.5.1 I was getting:
 {{{
 app.test1: Reverse query name for m2m field 'tests2' clashes with m2m
 field 'Test2.tests1'. Add a related_name argument to the definition for
 'tests2'
 }}}

 This is almost certainly because my field and model name is the same.
 Either way, I have solved it by adding `related_name` to `Test1.tests2`
 and taking the opportunity to suppress it from `Test2`:
 {{{
 class Test1(models.Model):
 tests2 = models.ManyToManyField('Test2', related_name='test2_set+',
 blank=True)

 class Test2(models.Model):
 tests1 = models.ReverseManyToManyField(Test1,
 through=Test1.tests2.through, blank=True)
 }}}

Comment (by CB):

 To update comment 28:

 This works great, but breaks south. So here's a fix for that:
 {{{
 class ReverseManyToManyField(models.ManyToManyField):
 pass
 try:
 import south
 except ImportError:
 pass
 else:
 from south.modelsinspector import add_ignored_fields
 add_ignored_fields([".*\.ReverseManyToManyField$",])

 class Test1(models.Model):
 tests2 = models.ManyToManyField('Test2', blank=True)

 class Test2(models.Model):
 tests1 = models.ReverseManyToManyField(Test1,
 through=Test1.tests2.through, blank=True)
 }}}

 A possible Django enchancement would be adding this field (or rather, the
 results of it's contribute_to_class, I think) instead of the
 ReverseManyRelatedObjectsDescriptor

 Check this out

 {{{
 class Test1(models.Model):
 tests2 = models.ManyToManyField('Test2', blank=True)

 class Test2(models.Model):
 tests1 = models.ManyToManyField(Test1, through=Test1.tests2.through,
 blank=True)
 }}}

 I guess this is the most native way

Comment:

 etienned's solution did not work for me, I am doing this instead:

 {{{

 class User(models.Model):
 groups = models.ManyToManyField('Group',
 db_table='testapp_user_groups')

 class Group(models.Model):
 users = models.ManyToManyField('User',
 db_table=User.groups.field.db_table)
 Group.users.through._meta.managed = False
 }}}


 This will also work for non symmetrical self M2M relationships:
 {{{

 class User(models.Model):
   supervisors = models.ManyToManyField('self',
 related_name='underlings_set', db_table='testapp_user_supervisors')
   underlings = models.ManyToManyField('self',
 related_name='supervisors_set', db_table=supervisors.db_table)
   underlings._get_m2m_attr = supervisors._get_m2m_reverse_attr
   underlings._get_m2m_reverse_attr = supervisors._get_m2m_attr
 User.underlings.through._meta.managed = False
 }}}

Comment (by etienned):

 I found a solution that works with 1.2. Here it is:

 {{{
 #!python
 class User(models.Model):
 groups = models.ManyToManyField('Group', through='UserGroups')

 class Group(models.Model):
 users = models.ManyToManyField('User', through='UserGroups')

 class UserGroups(models.Model):
 user = models.ForeignKey(User)
 group = models.ForeignKey(Group)

 class Meta:
 db_table = 'app_user_groups'
 auto_created = User

 }}}

 This way ''syncdb'' create the ''UserGroups'' table only one time (because
 ''users'' and ''groups'' have ''through'' as argument) but the admin think
 is ''auto_created'' so it show the ''ManyToManyField'' directly for both
 ''User'' and ''Group''.

 But that's definitely a lot of trouble to have the field in both model
 admin pages. I don't think the solution is to modified ''syncdb'' either.
 I think russellm's suggestions are good avenues.

 To fix it for 1.2, all needed is to change:

 {{{
 self.creates_table = False
 }}}

 to:

 {{{

Comment (by russellm):

 There's at least one simple approach for backwards compatibility: reverse
 m2ms are only included if they are explicitly listed in the fields list.
 Alternatively, we add an 'include_reverse_m2m' flag.

 For 2.0, we can consider dropping the flag and making reverse m2m the
 default. It's a little inconvenient, but that's the price of backwards
 compatibility.

 Doesn't look like there's been much activity on this bug for a while, but
 I'd like to point out that the workaround posted by anonymous (Django
