如何将图像上传到Rails文章

Question

我正在Rails中重建博客，并且我正在使用Trix作为我的文本编辑器。我有关于Trix设置的所有内容。我可以拖动图像并将其放入Trix文本编辑器中，当我单击“创建文章”时，我没有错误。但是当我去看文章时，没有图像。这似乎是一个非常容易解决的问题。

show.html.erb

<h1>Showing Blog Posts</h1>

<p>
  <strong>Title:</strong>
  <%= @article.title %>
</p>

<p>
  <strong>Text:</strong>
  <%= @article.text.html_safe %>
</p>

<%= link_to 'Back', articles_path %>

article_controller.rb

class ArticlesController < ApplicationController
    def index
       @articles = Article.all 
    end

    def show
       @article = Article.find(params[:id]) 
    end

    def new
        @article = Article.new
    end

    def create
        @article = Article.new(article_params)

        if @article.save
          redirect_to @article
        else
          render 'new'
        end
    end

    def update 
       @article = Article.find(params[:id])

       if @article.update(article_params)
           redirect_to @article
       else
           render 'edit'
       end
    end

    private
        def article_params
            params.require(:article).permit(:title, :text)
        end
end
