Beginner> When developing Cho-A

The target is a comment If the user is the target of clicking like,
It's good to keep the user and comments in an n:m relationship You can create and manage tables.

It's good to have user's fk and comment's fk I just need a table.
If a user presses like on b comments, creating a like record with a.id and b.id increases one like, and
If you press like again, there is already a record, so it's good to delete it You will be able to implement cancellation.

features non-members not support if it because it is possible only in this case members.

If you are a non-member, I think it would be a good idea to organize it by dividing it into IP and User agent information.

If the basic user's pk is a non-member, it is good to satisfy both members and non-members by creating a separate key followed by the 'ip+user agent value I think it's a system.

Crying... Masters!
