Référence de ressource imbriquée [Modèle] doit exister erreur sur formulaire soumettre

Question

J'ai regardé toutes sortes de threads sur la même erreur et essayé différentes choses que les gens ont suggéré, mais ne semble pas comprendre celui-ci. J'utilise Rails 5 et continuer à obtenir cette erreur lorsque je tente de soumettre ma forme:

Step reference must exist 

Voici mes itinéraires

Rails.application.routes.draw do 
    resources :jobs do 
    resources :steps, except: [:index], controller: 'jobs/steps' 
     member do 
     patch :complete 
     end 
    end 

    get '/job/:id/next_step', to: 'jobs#next_step', as: 'next_step_jobs' 

    root "pages#home" 
end 

J'ai un modèle d'emploi et l'étape modèle

class Job < ActiveRecord::Base 
    has_many :steps, dependent: :destroy 
    accepts_nested_attributes_for :steps 

    def step_completed? 
    !steps.last.completed_at.blank? 
    end 
end 

class Step < ActiveRecord::Base 
    belongs_to :job, optional: true 
    belongs_to :step_reference 
end 

Voici les deux contrôleurs

class JobsController < ApplicationController 
    before_action :set_job, only: [:show, :edit, :next_step, :update] 

    # GET /jobs 
    def index 
    @dashboard = Dashboard.new 
    end 

    # GET /jobs/:id 
    def show 
    end 

    # GET /jobs/new 
    def new 
    @job = Job.new 
    end 

    # GET /jobs/:id/edit 
    def edit 
    end 

    # POST /jobs 
    def create 
    @job = Job.create(job_params) 
    if @job.save 
     # redirect to the next_step_path to ask questions 
     redirect_to next_step_jobs_path(@job), flash: { success: "Job successfully added" } 
    else 
     redirect_to new_job_path, flash: { danger: @job.errors.full_messages.join(", ") } 
    end 
    end 

    # PATCH /jobs/:id 
    def update 
    if @job.update(job_params) 
     redirect_to jobs_path, flash: { success: "Job successfully updated" } 
    else 
     redirect_to edit_jobs_path(@job), flash: { danger: @job.errors.full_messages.join(", ") } 
    end 
    end 

    # GET /jobs/:id/next_step 
    def next_step 
    # get question number from query string 
    @q = params[:q] 
    # create new instance of step 
    @next = Next.new 
    # pull the next_step object with question and answers to pass to the view 
    @next_step = @next.next_step(@job, @q) 

    if @next_step[:answers][0][:text].nil? 
     redirect_to new_job_step_path(@job) 
    else 
     @next_step 
    end 
    end 

    private 
    def set_job 
     @job = Job.find(params[:id]) 
    end 

    def job_params 
     params.require(:job).permit(:company, :position, :contact, :contact_email, 
     :posting_url, steps_attributes: [:step_reference_id, :job_id, :completed_at, :next_step_date]) 
    end 
end 



class Jobs::StepsController < ApplicationController 
    before_action :set_job 
    before_action :set_step, only: [:show, :edit, :update, :complete] 

    # GET /jobs/:job_id/steps/:id 
    def show 
    end 

    # GET /jobs/:job_id/steps/new 
    def new 
    @step = @job.steps.new 
    end 

    # GET /jobs/:job_id/steps/:id/edit 
    def edit 
    end 

    # POST /jobs/:job_id/steps/ 
    def create 
    @step = @job.steps.create(step_params) 
    if @step.save 
     redirect_to jobs_path, flash: { success: "Next step successfully added." } 
    else 
     redirect_to jobs_path, flash: { danger: @step.errors.full_messages.join(", ") } 
    end 
    end 

    # PATCH /jobs/:job_id/steps/:id 
    def update 
    if @step.update(step_params) 
     redirect_to jobs_path, flash: { success: "Next step successfully updated." } 
    else 
     redirect_to edit_job_step_path, flash: { danger: @step.errors.full_messages.join(", ") } 
    end 
    end 

    # PATCH /jobs/:job_id/steps/:id/complete 
    def complete 
    if @step.update_attribute(:completed_at, Date.today) 
     redirect_to jobs_path, flash: { success: "Job step completed" } 
    else 
     redirect_to jobs_path, flash: { danger: @step.errors.full_messages.join(", ") } 
    end 
    end 

    private 
    def set_job 
     @job = Job.find(params[:job_id]) 
    end 

    def set_step 
     @step = Step.find(params[:id]) 
    end 

    def step_params 
     params.require(:step).permit(:step_reference_id, :job_id, :completed_at, :next_step_date) 
    end 
end 

Et voici mon avis pour/Emploi /: JOB_ID/étapes/nouvelles

<h1 class="text-xs-center">New Step</h1> 

<%= form_for @step, url: job_steps_path(@job) do |f| %> 
    <div class="form-group"> 
    <%= f.label :next_step_date %> 
    <%= f.date_field :next_step_date, class: "form-control", id: "add-next-date-field" %> 
    </div> 
    <%= f.submit 'Save', class: "btn btn-primary" %> 
<% end %> 

Ainsi, le formulaire doit être soumettre à créer la méthode du StepsController, mais quand il soumet je reçois la « référence Step doit exister » erreur. Basé sur d'autres threads, il semble que cela puisse avoir à voir avec les paramètres forts, mais tout me semble assez standard.

Voici le journal du terminal

J'ai couchait avec cela pendant des heures, donc si quelqu'un peut faire la lumière je serais extrêmement reconnaissant !!!

Answer 1

Je pense que votre problème n'est pas lié à vos paramètres, mais plutôt à la façon dont vous avez construit votre formulaire. Généralement, la façon de faire des formulaires avec des attributs imbriqués consiste à utiliser l'assistant fields_for (info here).

donc votre formulaire devrait ressembler à ceci:

<%= form_for @job do |f| %> 
    <%= f.fields_for :steps do |steps| %> 
    <div class="form-group"> 
     <%= steps.label :next_step_date %> 
     <%= steps.date_field :next_step_date, class: "form-control", id: "add-next-date-field" %> 
    </div> 
    <% end %> 
    <%= f.submit 'Save', class: "btn btn-primary" %> 
<% end %>
