I have to connect to an external database which I don’t have control of.
They were not setup with a Rails application in mind. I can extract
information easily enough, but creating associations between the models
is my problem. I am not certain how exactly to let Rails know what the
primary key column is.
I have two tables, properties and photos. I would like to create an
association like this:
has_many :photos, :class_name => “Photo”, :foreign_key => “propNum”
belongs_to :property, :class_name => “Property”, :foreign_key =>
The properties table uses ‘propNum’ instead of ID. The photos table uses
photoNum instead of ID, and associates to the properties table using a
propNum column versus property_id.
I am not certain how exactly to specify what the primary column name is
so Rails can understand the association. Any help would be great.
