Table Relationship Reference Ruby on Rails -

i working on web application contractor (electrician, roofer, plumber) etc can make proposal online. pictures, youtube videos of project, , text description provided contractor customer.

so far working on pictures feature using carrierwave

this table of model in schema

  create_table "project_pictures", force: true |t|     t.string   "name"     t.string   "picture"     t.datetime "created_at"     t.datetime "updated_at"   end 

here 2 records in rails console

 projectpicture load (0.4ms)  select "project_pictures".* "project_pictures"  => #<activerecord::relation [#<projectpicture id: 2, name: "request siding quote customer a", picture: "siding.jpg", created_at: "2013-08-15 16:10:22", updated_at: "2013-08-15 16:47:02">, #<projectpicture id: 1, name: "request siding quote customer a", picture: "sidingrequest.jpg", created_at: "2013-08-14 01:54:27", updated_at: "2013-08-15 16:47:39">]>  

the thing trying link multiple pictures 1 customer. lets above 2 pictures belong 1 customer , there 2 rows because there 2 pictures.

how reference in table, lets have 1 customer , thats me "judy" both record should reference judy's id?

and in view, can draw both pictures out using image tag belong customer id 1 - name = "judy" or customer id = 1?

if not making things clear please let me know, not familiar tables relationships , relationship me most.

   create table :projects |t|     t.references :clients     t.timestamps   end
  
create_table :pictures |t|     t.string :name, null:false     t.string :location, null:false     t.references :projects, null:false     t.timestamps   end 

... meanwhile.. in model layer

 class project < activerecord::model    has_many :pictures, :dependent => destroy end
  
class picture < activerecord::model   belongs_to :project   validates_presence_of :project end 

to judy's pictures

client.where("name ?", "judy").projects.first.pictures
