我如何使其不刷新页面?相反,它只会更新计数数字吗?任何帮助,将不胜感激!
故事 Controller :
def like
like = Like.create(like: params[:like], user: current_user, story: @story)
if like.valid?
flash[:success] = "Your selection was succesful"
redirect_to :back
else
flash[:danger] = "You can only like/dislike a story once"
redirect_to :back
end
end
index.html.erb:
<div class="pull-right">
<%= link_to like_story_path(story, like: true), :method => :put, :remote => true do %>
<i class="glyphicon glyphicon-thumbs-up"></i><%= story.thumbs_up_total %>
<% end %>
<%= link_to like_story_path(story, like: false), :method => :put, :remote => true do %>
<i class="glyphicon glyphicon-thumbs-down"></i><%= story.thumbs_down_total %>
<% end %>
</div>
Story.rb模型:
def thumbs_up_total
self.likes.where(like: true).size
end
def thumbs_down_total
self.likes.where(like: false).size
end
最佳答案
Controller 应按照Working with JavaScript in Rails中的说明对respond_to
“格式”进行js
编码。
代替redirect_to :back
,以有意义的状态码响应,例如201(成功)(创建新资源时)或400(错误请求)。
参见RFC 2616, section 10 - Status Code Definitions。
然后,在您的JS中处理ajax:success
事件。 Working with JavaScript in Rails中也对此进行了描述。
