Rails - can't tell create controller which item to create

Question

I have several models:

• User
• Relationship
• Project

• Schedule

• A user instance can be of type :student or :employer.

• A schedule belongs_to a project and
• a project has_one schedule

• project belongs_to a student and a student has_many projects.

• A relationship belongs_to Student and relationship also belongs_to Employer. Employer and Student both has_many relationships.

I am writing the controller to create a schedule and I can't figure out how to tell the controller which project the schedule belongs to. Here is what I have so far

def create 
    if current_user.type == 'Employer'
        redirect_to employer_profile_path(current_user.profile_name) 
    else
        @schedule = Schedule.find(params[:id])
        if @schedule.save(schedule_params)     
            flash[:notice] = "Successfully created schedule."
            redirect_to profile_path(current_user.profile_name)  #change to project path later
        else
            render :action => 'new', :notice => 'Invalid Schedule'
        end
    end
end

private
def schedule_params
      params.require(:schedule).permit(tasks_attributes: [:title, :content, :_destroy]) 
end

I am pretty sure I am defining @schedule incorrectly. The routes for schedule are:

resources :schedules

How do I tell the controller which Project the schedule belongs to?

Answer 1

Assuming you posted the create action for the SchedulesController there is no need for:

@schedule = Schedule.find(params[:id])

this will probably return nil, because there is no schedule (after all that is what you want to create here).

@schedule = Schedule.new(schedule_params) 

if you want to assign a project to the schedule, you need to submit this information so you can access it in the params hash. Something like:

@schedule.project = Project.find(params[:project_id])
