I'm definitely a noob to rails so sorry if this is trivial. I have tables with associations on them. The associations are supposed to add methods to my models like model.others and model.others= and so on but when I try to use them I get errors like the following.
NoMethodError: undefined method `states' for #<Ad:0x2c8a88c> from C:/Ruby/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/attribute_methods.rb:260:in `method_missing' from (irb):4
I've followed the execution in the debugger and all that the method_missing seems to do is generate setters, getters and ? for the fields in the table, it doesn't seem to generate or look for any of the methods that
says it should. I only did this once though and I didn't really understand what I was reading
My code is the following
Model classes:
file: app/models/ad.rb class Ad < ActiveRecord::Base belongs_to :customer has_and_belongs_to_many :state end
file: app/models/state.rb class State < ActiveRecord::Base has_and_belongs_to_many :ad has_many :zip_code has_many :town end
Migration:
create_table :ads do |t| t.integer :property_type_id t.float :priority_weighting t.float :price_min t.float :price_max t.float :distance_max t.boolean :for_sale t.boolean :for_lease t.float :cost_per_click t.float :cost_per_click t.references :customer t.binary :image_size_1 t.binary :image_size_2
t.timestamps end
create_table "states", :force => true do |t| t.string "name" t.string "abbreviation" end
create_table "ads_states", :force => true do |t| t.integer "ad_id" t.integer "state_id" end
(actually I took this from schema.rb)
when I run script/console and play around I get this:
state = State.new
=> #<State id: nil, name: nil, abbreviation: nil>
state.save
=> true
ad = Ad.new
=> #<Ad id: nil, property_type_id: nil, priority_weighting: nil, price_min: nil, price_max: nil, distance_max: nil, for_sale: nil, for_lease: nil, cost_per_click: nil, customer_id: nil, image_size_1: nil, image_size_2: nil, created_at: nil, updated_at: nil>
ad.state
=>
ad.state_ids
=>
ad.state_ids = [state.id]
=> [2]
ad.states
NoMethodError: undefined method `states' for #<Ad:0x419db84> from C:/Ruby/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/attribute_methods.rb:260:in `method_missing' from (irb):20
ad.states = [state]
NoMethodError: undefined method `states=' for #<Ad:0x419db84> from C:/Ruby/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/attribute_methods.rb:255:in `method_missing' from (irb):21
ad.states << [state]
NoMethodError: undefined method `states' for #<Ad:0x419db84> from C:/Ruby/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/attribute_methods.rb:260:in `method_missing' from (irb):22
I have similar problems with has_many however belongs_to seems to work.
I get the same exact problems when I try this in the controller. I'm using Rails 2.3.5 and Ruby 1.8.7
Please let me know if you need any more info this is all I could think of.
