如何使用印象派 gem rails 修复此错误

如何解决如何使用印象派 gem rails 修复此错误

嗨，我对印象派宝石有误。我使用 Rails 5.2.4.4

我做了这些步骤：

宝石“印象派”

然后捆绑安装

然后 Rails g 印象派和捆绑安装

然后下一步：

in my blogs_controllers

class BlogsController < ApplicationController
    before_action :authorize_admin,only: [:new,:edit,:create,:update]
    before_action :set_blog,only: [:show,:update,:destroy]
  impressionist :actions => [:show,:index]

  def index
    @categories = Category.all

    cate = params[:cate]

    if !cate.nil?
        @blogs = Blog.where(:category_id => cate)
    else
        @blogs = Blog.all
    end
  end

  def show
    impressionist(@blog)
  end

  def new
    @blog = Blog.new
  end

  def create
    @blog = Blog.new(blog_params)

    if @blog.save
        redirect_to blog_path(@blog),notice: "Successfully Created"
    else
        render :new
    end
  end

  def edit
  end

  def update
    @blog.slug = nil
    if @blog.update(blog_params)
    redirect_to blog_path(@blog),notice: "Successfully Update"
    else
      render 'edit'
    end
  end

  def destroy
    @blog.destroy
    redirect_to blogs_path
  end

  private

    def set_blog
      @blog = Blog.find(params[:id])
      
    end

  def blog_params
    params.require(:blog).permit(:title,:body,:image,:category_id)
  end

  def authorize_admin
    return unless !current_user.admin?
    redirect_to root_path
  end
end

在博客模型中

is_impressionable

在博客展示

<%= @blog.impressionist_count(:filter=>:ip_address) %>

我得到了这个错误：

BlogsController#show 中的名称错误
