Do I have to create the join tables?

Hello,

Suppose I have the following tables:

table X ( id name )

table Y ( id name )

And I have a many to many relation between them. So, I put in each of the tables the "has_and_belongs_to_many". In the real database it should be a X_Y join table. Do I have to create that table with a migration or the model will take care of that?

you have to create it with a migration (or by hand, phpmyadmin, or some other software)

example: Model 1: Post Model 2: Authror

Join table: authors_posts

Rule for the table name: order of model names alphabetically. both model names pluralized

generally i suggest has_many_through over has_and_belongs_to_many, as it let's you access the join table thorugh it's own model...
