我介紹和評論,每個演示讓許多意見和這些意見可以這樣說時,渲染匹配...的Rails的link_to募集不僅路由錯誤從JS
在我的陳述顯示,我成功地使這個評論方法:
<div id= "container_comments">
<%= render @presentation.comments.where(ancestry: nil) %>
</div>
這種方式,所有的評論都是使用這個基礎_comment.html.erb文件中呈現
<div class="media" id="comment_<%= comment.id %>">
<div class="media-left">
<img src="<%= image_path("comment.png")%>" class="media-object" style="width:45px">
</div>
<div class="media-body">
<h4 class="media-heading"><%=User.find(comment.author_id).username%> <small><i>Publicado: <%=comment.created_at.strftime('%F %T') %></i></small></h4>
<p><%=comment.body%></p>
<%= link_to "Reply", new_comment_congress_category_presentation_comment_path(@congress, @category, @presentation, :parent_id => comment), :class => "btn", :remote => true, "data-toggle" => "modal", "data-target" => "#mynewcomment"%>
<% replies = Comment.where(ancestry: comment) %>
<% if replies.any? %>
<% replies.each do |reply| %>
<div class="media">
<div class="media-left">
<img src="<%= image_path("reply.png")%>" class="media-object" style="width:45px">
</div>
<div class="media-body">
<h4 class="media-heading"><%=User.find(reply.author_id).username%> <small><i>Publicado: <%=reply.created_at.strftime('%F %T') %></i></small></h4>
<p><%=reply.body%></p>
</div>
</div>
<%end%>
<%end%>
</div>
</div>
一切工作正常這裏,prese ntation負荷評論和回覆正常,問題是回答的的link_to:
<%= link_to "Reply", new_comment_congress_category_presentation_comment_path(@congress, @category, @presentation, :parent_id => comment), :class => "btn", :remote => true, "data-toggle" => "modal", "data-target" => "#mynewcomment"%>
至極從演示放映視圖correclty負載不允許從JS文件的呈現,它顯示「無路由匹配」錯誤與遺漏鍵[ :ID]。
這是我的js文件:
$("#mynewcomment").modal('hide');
$(".comment_title").val('');
$(".comment_content").val('');
<%if @comment.parent == nil%>
$("#container_comments").append('<%= j render @comment %>');
$("#comment_<%= @comment.id %>").hide().fadeIn(1000);
<%else%>
<%@parent = Comment.find(@comment.parent_id)%>
$("#comment_<%= @parent.id %>").replaceWith('<%= j render @parent %>');
<%end%>
這裏是錯誤的樣子:
ActionView::Template::Error (No route matches {:action=>"new_comment", :category_id=>#<...category info here...>, :congress_id=>#<...congress info here...>, :controller=>"comments", :parent_id=>#<...parent comment info here...>, :presentation_id=>#<...Presentation info here...>}, missing required keys: [:id]):
7: <p><%=comment.body%></p>

我不知道確切的同一個文件是如何失敗的渲染throught js的....我真的對你的幫助感到滿意,這是我完成第一個鐵軌項目的唯一步驟,再次感謝!
