Question

I have a Model called Status, its handling a table with two columns Stat and Colour.

Since these columns are also Model methods I would expect the following to work without an error

@a = Status.where(:stat => "Operational")
@a.colour = "Green"

However when I call @a.colour I receive an error stating that the method ‘colour=’ does not exist.

I am calling @a.colour from within seeds. This is just a model, it does not have a controller with it.

What am i doing wrong?

–Edit–

Model

class Status < ActiveRecord::Base
end

schema

  create_table "statuses", :force => true do |t|
    t.string   "stat"
    t.string   "colour"
    t.datetime "created_at", :null => false
    t.datetime "updated_at", :null => false
  end

Is this what you requested? I did not fully understand the request,

Kind Regards

Answer 1

I suppose Status.where() returns more than one record. So you are trying to call the color= method on an array which obviously does not exist!

So you need to iterate trough all found records, using

Status.where(:stat => "Operational").each do |a|
   a.colour = "Green"
end

For more information check the Rails ActiveRcord Query Interface guide, it tells you:

If you’d like to add conditions to your find, you could just specify them in there, just like Client.where(“orders_count = ‘2’”). This will find all clients where the orders_count field’s value is 2.
