php - Laravel many to many relashionship -


i have users, meetings , comments tables , want users able post comments on users profile , meetings.

i know how make 1 many relationships users , comments tables, want comments saved in 1 table , show comments on users profile , meetings.

this table structure:

users id name comment_id  meetings id name  comments id user_id comment

tl;dr solution use polymorphic relationships laravel makes easy.

imho don't think many-to-many relationship job. mean that:

  • a user can post multiple comments. okay
  • a comment can belong multiple user. weird
  • a meeting can have multiple comments. okay
  • a comment can belong multiple meetings. weird

plus need 2 comments tables achieve that. instance comment_user table , comment_meeting.

the kind of relationship fit situation polymorphic one. name can scary because comes ancient greek. concept behind name simple. , laravel makes polymorphic relationships easy. recognize situation in example given in laravel documentation ;)
