RSpec控制器测试从不调用创建

Question

我试图通过rspec在控制器中测试创建方法，但无法获得进入控制器或创建方法之前存在的任何回调的测试。这是我的控制器

# frozen_string_literal: true
class Admin::TaggingsController < Admin::BaseController
  before_action :check_tag, only: [:create]

  def create
    debugger
    unless (@tag = Tag.find_by('lower(name) = ?', tagging_params[:name].downcase))
      @tag = Tag.create(name: tagging_params[:name])
      @tag.created_by ||= current_admin_user.id
    end
    @tagging = Tagging.new(taggable_type: params[:tagging][:taggable_type],
                           taggable_id: params[:tagging][:taggable_id],
                           tag: @tag)
    if @tagging.with_user(current_admin_user).save
      respond_to do |format|
        format.js {}
      end
    else
      respond_to do |format|
        format.js { render text: "console.log('tag save error (tag may already exist)')" }
      end
    end
  end

  def bulk_create
    unless (@tag = Tag.where('lower(name) = ?', tagging_params[:name].downcase).first)
      @tag = Tag.create(name: tagging_params[:name])
      @tag.created_by ||= current_admin_user.id
    end
    taggings = []
    tagging_params[:taggable_ids].each do |id|
      taggings.push(Tagging.find_or_create_by(taggable_type: tagging_params[:taggable_type] || 'Person',
                                              taggable_id: id,
                                              tag: @tag))
    end
    if taggings.count == tagging_params[:taggable_ids].count
      flash[:notice] = 'Tags applied successfully'
    else
      flash[:warning] = 'Problem applying tags'
    end
    redirect_to :back
  end

  def destroy
    @tagging = Tagging.find(params[:id])

    if @tagging.destroy
      respond_to do |format|
        format.js {}
      end
    else
      respond_to do |format|
        format.js { render text: "alert('failed to destroy tag.')" }
      end
    end
  end

  def search
    @tags = Tag.where('name like ?', "%#{params[:q]}%").
            order(taggings_count: :desc)
    render json: @tags.to_json(methods: [:value, :label, :type])
  end

  private

    def tagging_params
      params.require(:tagging).permit(:taggable_type, :taggable_id, :name, taggable_ids: [])
    end

    def check_tag
      debugger
      redirect_to :back if tagging_params[:name] == ''
    end
end

这是我的rspec测试

RSpec.describe Admin::TaggingsController do
  describe 'POST create' do

    it 'Does not create taggings with empty tag names' do 
     post :create, params: {name:"waffles"}
    end

  
   
  end
end

这时，我只是想让RSPEC进入控制器。非常感谢您的帮助。
