Hi Guys,

I have some issues with the below table relationship.

table_users
id
name

table_invoice
id
date

table_user_invoices
user_id
invoice_id

It doesn't seem to be easy way to manage the has_many for the above tables.

Looking forward for your advise.

Best Regards,
Sydore Pry

Hi Sydore,

There are two ways to work out, many-to-many relationship, has_many
:through<http://guides.rubyonrails.org/association_basics.html#the-has_many-th...>,
and has_and_belongs_to_many<http://guides.rubyonrails.org/association_basics.html#the-has_and_bel...>
. Check out the differences in the Rails
Guide<http://guides.rubyonrails.org/association_basics.html#choosing-betwee...>
.

In this case, I would suggest you to use has_and_belongs_to_many.

Cheers,
Chamnap
