Sinatra and post datamapper association

I am building a rest api with sinatra and datamapper and I have my database file which looks like this:

require 'data_mapper'

DataMapper.setup(:default,'sqlite::memory:')


class Company
 include DataMapper::Resource

 property :id, Serial
 property:name, String, :required => true
 property:adress,String,:required => true
 property:city,String, :required => true
 property:country,String,:required => true
 property:email,String
 property:phoneNumber,Numeric
 has n, :owners, :constraint => :destroy

end

class Owner
 include DataMapper::Resource

 property :id,Serial
 property:name,String, :required => true
 property:id_company,Integer, :required =>true

 belongs_to:company
end

DataMapper.finalize
DataMapper.auto_migrate!

and I want to make a post method to add an owner to a company

post '/owners'do
  content_type :json
  owner = Owner.new params[:owner]
  if owner.save
    status 201
  else
    status 500
    json owner.errors.full_messages
  end
end

but when I tried to run this request I get this error :

curl -d "owner[name]=rrr & owner[id_company]=1" http://localhost:4567/owners
["Company must not be blank"]

Can somebody tell me how to make the association between the company and the owner in the post method?

Solution

  • The problem is that it should not be id_company has to be company_id, changing...

     property:id_company,Integer, :required =>true

    by

    property :company_id,Integer, :required =>true

    and doing curl on this way, has to fix this error 

    curl -d "owner[name]=rrr & owner[company_id]=1" http://localhost:4567/owners
