在/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_ujs
到require rails-ujs
并添加了rails-ujs gem。
