/tags页面,我有remote: true的链接。它应该是ajax请求的链接。但有两个请求,如JS和HTML。

<%= link_to 'New', new_tag_path, class: "btn btn-outline btn-primary", remote: true %>

如果我提供new.html.erb,则此MissingTemplate错误已结束,但页面将重定向到new.html。 该请求或该链接可能出现什么问题?

编辑控制器代码     class TagsController&lt; ApplicationController的       before_action:set_tag,only:[:show,:edit,:update,:destroy,:fix_correct_name]       before_action:set_tags,仅限:[:new,:edit]

  # GET /tags/new
  def new
    @tag = Tag.new
  end

  # GET /tags/1/edit
  def edit
  end

  # POST /tags
  def create
    @tag = Tag.new(tag_params)

    respond_to do |format|
      if @tag.save
        format.html { redirect_to action: "index", notice: 'Tag adicionada.' }
      else
        format.html { render :new }
      end
    end
  end

  private
    # Use callbacks to share common setup or constraints between actions.
    def set_tag
      @tag = Tag.find(params[:id])
    end

    def set_tags
      @tags = Tag.all.pluck(:name, :id)
    end

    # Never trust parameters from the scary internet, only allow the white list through.
    def tag_params
      params.fetch(:tag, {}).permit(:name, :parent_id, :tag_name, :parent_name, :no_parent)
    end
end

在您的新操作中,您需要response_to来处理ajax调用

def new
  @tag = Tag.new
  respond_to { |format| format.js }
end 

此外,您需要一个new.js.erb文件和一个_new.html.erb部分来处理响应并更新视图。

在new.js.erb中,您必须使用类似的内容呈现视图

$(“div-id-name”).html(“<%= j render partial: “new” %>”) 

而你的新部分只会保留你的形式(或者你想呈现的任何内容)

我现在已经开始工作了,只是将int ri = func(); 替换为require jquery_ujsrequire rails-ujs并添加了rails-ujs gem。
