TicketType(#70316537311800) expected, got String(#10085740)

app/controllers/reasons_controller.rb:44:in `new' app/controllers/reasons_controller.rb:44:in `create'

View:

<%= f.label :ticket_type %><br /> <%= f.select :ticket_type, TicketType.all.collect {|t| [ t.description, t.description]}, {:include_blank => "Please select one"}, :method => 'get'%>

Controller:

@reason = Reason.new(params[:reason])

respond_to do |format|       if @reason.save         format.html { redirect_to manage_tickets_path, notice: 'Reason was successfully created.' } etc

Model:

class Reason < ActiveRecord::Base   validates :description, :ticket_type, :presence => true         attr_accessible :description, :ticket_type

  belongs_to :ticket_type, :foreign_key => :ticket_type end

class TicketType < ActiveRecord::Base         attr_accessible :description

  has_many :reasons, :foreign_key => :ticket_type end

I have read the "Kitchen" posting about the same error, the only problem is i am using a description, not ID. Changing the form just gives errors, any help would be greatly appreciated. Thanks!

If you have the foreign key column called ticket_type and also belongs_to ticket_type, then when you do @reason.ticket_type how is rails going to know whether you want the value of the column or the associated object? Best to stick to the conventions and call the column ticket_type_id.

By the way, when posting an error it is a good idea to tell us which line is the line the error refers to (ie which is line 44 in this case) in order to save us having to work it out ourselves.
