Question

我尝试构建一个带有两个轴承的嵌套表单（= post do push do reviews）我有这个错误：

我想知道我是否有成功创作的良好做法？

我的代码

查看/推手/显示：

AudioManager manager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);

int audioSessionId = manager.generateAudioSessionId();

EqualizerModel.getInstance().setEqualizer(new Equalizer(0, audioSessionId));

评论/控制器：

<%= link_to 'Add comment', new_post_push_review_path(@push.post_id, @push) %>

查看/评论/新：

class ReviewsController < ApplicationController
  before_action :authenticate_user!
  before_action :find_post
  before_action :find_push

  def new 
    @review = Review.new 
  end 

  def create
    @review = @post.push.reviews.create(review_params)
     @review.post_id = @push.post_id
    @review.push_id = @push.id 
    @review.user_id = current_user.id

    if @review.save 
      redirect_to push_path(@push.post_id, @push)
    else 
      render 'new'
    end 
  end 

  private 

  def review_params
    params.require(:review).permit(:rating, :comment)
  end 

  def find_post
    @post = Post.find(params[:post_id])
  end 

  def find_push
    @post = Post.find(params[:post_id])
    @push = Push.find(params[:push_id])
  end 

end

＆安培;路线：

<%= simple_form_for([@post, @post.push.reviews.build]) do |f| %>
  <%= f.input :rating %>
  <%= f.input :comment %>
  <%= f.button :submit %>
<% end %>

构建嵌套表单的第二步？
