22852	WHY: (admin.E013) The value of 'fields' cannot include the ManyToManyField 'make_types', because that field manually specifies a relationship model?	sharma_salient@…	nobody	"Will any one tell me why `checks.py` throws this error if I've manually defined the M2M relation table using through?

What's the difference in auto created and manually defined models class?

What's the wrong is if we're adding parameters `through` and `through_fields`? Surely auto created model/table need a class and two fields. So, manually created model/table also has same thing!"	Bug	closed	contrib.admin	dev	Normal	duplicate	M2M, admin, through, through_fields		Unreviewed	0	0	0	0	0	0
