Rails 4 has_and_belongs_to_many -- locations & organizations

Development

Hi Tom,

Per the discussion on irc regarding the Rails 4 branch, note that there is a separate join table 'locations_organizations' to handle:

class Location < Taxonomy

has_and_belongs_to_many :organizations

class Organization < Taxonomy

has_and_belongs_to_many :locations

The problem you were problem facing is that Rails 4 changes the naming convention of the join table.

class Location < Taxonomy

has_and_belongs_to_many :organizations, join_table: : locations_organizations

class Organization < Taxonomy

has_and_belongs_to_many :locations, join_table: : locations_organizations

Otherwise it will look for a table ' location_organizations ' (NO 's') and fail.

I would not include the relationship between Location / Organization in taxable_taxonomies.

yup. it actually looked for taxonomies_taxonomies, which makes even less
sense…
Thanks, Joseph!

Tom,

Are you sure? I'm pretty sure it would look for locations_organizations and not taxonomies_taxonomies unless I'm missing something.

a
separate join table ‘locations_organizations’ to handle:

class Location < Taxonomy

has_and_belongs_to_many :organizations

class Organization < Taxonomy

has_and_belongs_to_many :locations

The problem you were problem facing is that Rails 4 changes the naming
convention of the join table.

class Location < Taxonomy

has_and_belongs_to_many :organizations, join_table: :
locations_organizations

class Organization < Taxonomy

has_and_belongs_to_many :locations, join_table: : locations_organizations

Otherwise it will look for a table ’ location_organizations ’ (NO ‘s’) and
fail.

I would not include the relationship between Location / Organization in
taxable_taxonomies.
