Have three models: Company, Job and JobApplications. When submitting the job form, the company_id and job_id are showing up as nil in the rails console. What's the best way to assign both company_id and job_id values for each job created by a company?

I've added the company_id and job_id to the companies and jobs tables. Within the create method of my jobs model, I've assigned @company_id to the job params and company_id and job_id are still showing as nil after creating a job.

Controller Actions

class CompaniesController < ApplicationController

 def new
    @company = current_user.build_company
 end

 def create
    @job = Job.new
    @company = Company.new(company_params)
 end

private
  def set_company
    @company = Company.find(params[:id])
  end

  def company_params
    params.require(:company).permit(:avatar, :name, :website, :about)
  end

class JobsController < ApplicationController

 def new
    @job = Job.new(:company_id => params[:id])
    @company_id = params[:job][:company_id]
 end

    # @job = current_user.jobs.build(job_params)
    @job = Job.find(params[:job_id])
    # @company = @job.company
    @job = Job.create(job_params.merge(user: current_user, company_id: current_user, job_id: @job))
    @company_id = params[:job][:company_id]
 end

  @job = Job.find_by(id: params[:id])
   if @job.nil?
     redirect_to jobs_path
