How does one populate a join table using a data migration?
Here's the situation. I have a HABM relationship between authors and
books; both tables are created and populated. I've created the join
table, authors_books, to contain author_id and book_id.
I want to use a data migration to populate the table-what's the code
for this? Since there isn't a model for the join table, it's not an
object...
If I want to add data in a migration to the books table, I can simply use:
Book.create(:name => "Alice in Wonderland")
Likewise, the author table can migrate with data like so:
Author.create(:name => "Lewis Carroll").
If the book_id is 1, and the author_id is 1, how do I get this
information in the join table?
Since it's not an object in and of itself, what's the code to create
and populate new rows in this table?
I know I can hack around it by creating a model for the join and
using the :through => New_Model to make the connection, but it seems
that there must be an easier way to get the basic data in the join
table and still have the version control over the data through the
data migration.
