    group_id = models . IntegerField () 
    name = models . CharField ( max_length = 255 )

since in this case it GroupMeetingis connected with one Meeting , but Meetingconnected with many GroupMeeting

Answer 1

Somehow you contradict yourself
GroupMeeting can have many Meetings
and Meeting Only one group ..
So if I choose 1 meeting for 2 different groups, then it turns out that the meeting will already have 2 groups ...
I see only through
group = models.ForeignKey(GroupMeeting....)
Maybe someone else will have ideas
