我正在尝试将Upvote函数与acts_as_votable
gem一起使用。我遇到的问题是,当我将鼠标悬停在Upvote链接上时,我可以看到comment.id
没有给出URL预览,然后当我点击Upvote时,确定的错误消息告诉我:
Couldn't find Comment with 'id'=#
<Comment::ActiveRecord_Relation:0x007f813b169658>
我的观点中的评论循环如下所示:
<div class="box">
<% @comment.each do |w| %>
<tr>
<td><b><%= w.title %></b></td><br>
<td><%= w.location %></td><br>
<td><%= w.body %></td><br>
<%= link_to "upvote", like_comment_path(@comment), method: :put
%><br>
</tr>
<% end %>
</div>
我的 CommentsController :
def upvote
@comment = Comment.find(params[:id])
@comment.upvote_by current_user
redirect_to comments_path
end
我的配置/路由:
resources :comments do
member do
put "like", to: "comments#upvote"
put "dislike", to: "comments#downvote"
end
end
这感觉它应该是非常简单的东西,但我无法弄清楚为什么没有给出id,所以非常感谢帮助: - )
答案 0 :(得分:0)
我假设您的@comment是评论的集合。如果是这样,那么您应该将@comment变量重命名为@comments并在视图中迭代@comments集合,如下所示:
<div class="box">
<% @comments.each do |comment| %>
<tr>
<td><b><%= comment.title %></b></td><br>
<td><%= comment.location %></td><br>
<td><%= comment.body %></td><br>
<%= link_to "upvote", like_comment_path(comment), method: :put
%><br>
</tr>
<% end %>
</div>
如您所见,您可以创建link_to更新您的评论项目,如下所示:
<%= link_to "upvote", like_comment_path(comment), method: :put
