Subject: Re: Rails DB convention info is a big fat secret??

Then off through the second "read more" to learn about associations.

http://api.rubyonrails.com/classes/ActiveRecord/Associations/ClassMethod
s.html#M000474

Your big secret table linking name is actually the most clear of the
documentations:

has_and_belongs_to_many(association_id, options = {}, &extension)
Associates two classes via an intermediate join table. Unless the join
table is explicitly specified as an option, it is guessed using the
lexical order of the class names. So a join between Developer and
Project will give the default join table name of "developers_projects"
because "D" outranks "P".

The documentation for the other table bindings is not quite as clear
(you have to read the doc to get it), but it's all there.


Anything you don't understand, the nice people at

to help.
