Rails 3.1 需要在索引页面上进行就地编辑 [英] Rails 3.1 Need to do in place editing on an Index page

问题描述

我有一个带有自由格式评论字段的索引页.Comment 字段是另一个不相关的模型的一部分——长篇大论、一部分我、一部分用户.

I have an index page with a free form comment field. The Comment field is part of another model that is not associated-- long story, part me, part user.

我需要弄清楚的是用什么来做到这一点.我遇到了 Best In Place 的问题 (此处) 并且不确定这是否是可解析的路径.

What I need to figure out is what to use to do that. I ran into a problem with Best In Place (here) and am not sure if that is a resolvable path.

那么，有没有人有教程或建议来指导我对索引进行就地编辑?

So, does anyone have a tutorial or advice to point me to regarding doing in place editing for an index?

推荐答案

我最终做的是:

在表格中创建一行是 TextArea 并为文本区域分配一个类:

<td class="textcell" id="<%= crb_agenda.key %>"><%= text_area_tag 'comment', if @pdms_comment.user_comments.nil? == false then @pdms_comment.user_comments end, :rows => 3, :id => "_" + @pdms_comment.jira_key %><%= link_to "[+]", "#", :class => "comment_row" %></td>

[对不起，我对这个格式有一段时间的困扰]

[sorry I am having a devil of a time with the formatting for this]

创建一个控制器来更新数据库中的字段:

  def comment_push
    @jira_key = params[:key]
    @comment = params[:comment]
    @user_name = params[:name]
    @user_pw = params[:pw]

    @comment_record = Comment.find_by_jira_key(@jira_key)
    @comment_record.update_attribute(:user_comments, @comment)

    Comment.add_comment_to_jira_ticket(@user_name, @user_pw, "MCTEST-293",@comment)

    respond_to do |format|
      format.js
    end
  end
 [note, this required a comment.js.erb file in the views; it was blank. Also, I created a route for it]

根据我分配给文本区域的类创建一个 jquery 函数，该类将必要的参数从控制器传递到路由...

  $('.comment_row').live("click", function() {
        var user_name = $('#user_name').val();
        var user_pw = $('#user_pw').val();
        var tr = $(this).closest("tr");
        var td = $(this).closest("td");
        var ta_id = '_' + td.attr("id");
        var comment = $('textarea#' + ta_id).val();
        $.ajax({
            url: '/crbagenda/comments/comment_push',
            type: 'GET',
            data: 'key=' + td.attr("id") + "&name=" + user_name + "&pw=" + user_pw + "&comment=" + comment
        });

这就解决了.
