我在用户页面上有基于ajax 的微博评论。它有效,但不正确。当我向任何 微博提交新评论时,它总是发布到最后 微博。然后,如果我按“F5”刷新页面,一切就绪——新评论出现在正确的微博中。提前致谢。
comment.rb
class Comment < ActiveRecord::Base
attr_accessible :comment_content
belongs_to :user
belongs_to :micropost
end
comments_controller.rb
class CommentsController < ApplicationController
before_filter :signed_in_user, only: [:create, :destroy]
def create
@micropost = Micropost.find(params[:micropost_id])
@comment = Comment.new(params[:comment])
@comment.micropost = @micropost
@comment.user = current_user
respond_to do |format|
@comment.save
format.html { redirect_to current_user }
format.js
end
end
end
_micropost.html.erb
<tr>
<td class="micropost">
<span class="content"><%= wrap(micropost.content) %></span>
<span class="timestamp">
Posted <%= time_ago_in_words(micropost.created_at) %> ago.
</span>
<%= render 'shared/comment_form', micropost: micropost %>
<div id="comments">
<%= render micropost.comments %>
</div>
</td>
</tr>
_comment_form.html.erb
<%= form_for ([micropost, @comment]), :remote => true do |f| %>
<%= render 'shared/error_messages', object: f.object %>
<%= f.text_area :comment_content, :size => "40x2" %>
<button class="btn" type="submit">
Comment
</button>
<% end %>
_comment.html.erb
<span style="width: 100%; background:#dff0d8"><%= wrap(comment.comment_content) %></span>
<span class="timestamp">
Posted by <%= comment.user.name %> <%= time_ago_in_words(comment.created_at) %> ago.
</span>
create.js.erb
$('#comments').html("<%= escape_javascript(render(:partial => @micropost.comments)) %>");
最佳答案
也许你可以改变
@comment = Comment.new(params[:comment])
@comment.micropost = @micropost
到
@comment = @micropost.comments.build(params[:comment])
