Associations

Hello,

If user --> has_many :address

How can we do a build_address as it expects a has_one relationship?

Thanks,
Avi

@user.addresses.build( … )

Have a look at the Rails Guide on ActiveRecord Associations. It shows
all the methods available for each association type.

The association is created by a foreign key on addresses which should
be user_id unless you want a custom field (for example I would
prefer it to be uid so I tell them that is the case but you need to
read the links provided by others to see how to do that.) Then to the
easiest way to create records on the association is:

User.find_by_email(“[email protected]”).addresses.new

Though again, for the sake of context and readability I prefer to also
alias all my associations to their singular form for creation because
to me it makes no sense to do User.new.addresses.new when you are only
creating a single address, it only makes sense when pulling the them.
