How to lookup Company_id that has the current User - ruby-on-rails

Question

I want to create a new jobdescription with company_id from the current user, but it doesn't work, I tried different ways and it's still not working.
So, I don't know how to build the query in my controller, if you can tell me where the issue is, that would be very kind of you. Thanks.
Schema.rb
ActiveRecord::Schema.define(version: 20150212182839) do
create_table "companies", force: true do |t|
t.string "company_name"

t.datetime "created_at"
t.datetime "updated_at"
end
create_table "jobdescriptions", force: true do |t|
t.string "applyjobid"
t.string "job_title"
t.string "department"
t.text "shift"
t.string "work_location"

add_index "users", ["company_id"], name: "index_users_on_company_id"

t.integer "role_id"
end
add_index "users_roles", ["user_id", "role_id"], name: "index_users_roles_on_user_id_and_role_id"
end
Here is my JobdescriptionsController
class JobdescriptionsController < ApplicationController
layout 'application'
def new
#jobdescription = Jobdescription.new
end
def create
#jobdescription = current_user.company_id.jobdescriptions.create(jobdescription_params)
redirect_to new_jobdescription_path
end
private
def jobdescription_params
params.require(:jobdescription).permit(:applyjobid, :job_title, :work_location, :rate_pay, :shift, )
end
end
Model Jobdescription
class Jobdescription < ActiveRecord::Base
belongs_to :company
end
Model Company
class Company < ActiveRecord::Base
has_many :users
has_many :jobdescriptions
end
Model User
class User < ActiveRecord::Base
rolify
default_value_for :role_id, "1"
# Include default devise modules. Others available are:
# :confirmable, :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
has_many :timesheets
has_many :expenses
belongs_to :company
end

Answer 1

I think the problem is that current_user.company_id gives the integer value of the company_id for that user's company, when what you actually want is to get the company object instance itself. Then you can call create on that company instance.
So the assignment for #jobdescription in the create method would be:
#jobdescription = current_user.company.jobdescriptions.create(jobdescription_params)
