    <p>I'm building a Q&amp;A site where one can comment on questions and their answers.Its a threaded commenting system with ajax.</p> <p><strong>this is the javascript part:</strong></p> <pre><code>function bindPostCommentHandler() { $('.commentFormWrapper form').submit(function() { var current = $(this); $.ajax({ type: "POST", data: current.serialize(), url: "{% comment_form_target %}", cache: false, dataType: "html", beforeSend:function(xhr){ $('.submit', current).html('&lt;img id="preloader" class="va-mid" src="{{MEDIA_URL}}img/indicator.gif" title="processing.." /&gt;'); $('#commentError').remove(); }, success: function(html, textStatus) { current.parent().replaceWith(html); bindPostCommentHandler(); }, error: function(xhr, textStatus, errorThrown) { $('#commentError').remove(); $('.submit', current).html('&lt;input type="submit" name="submit" class="submit-post small-button" value="Submit" /&gt;'); if(xhr.status == 400){ current.before('&lt;li id="commentError" class="no-bullet errornote margin10"&gt;OOPS ! your comment looked liked a spam. Try again with some modifications.&lt;/li&gt;'); }else { current.before('&lt;li id="commentError" class="no-bullet errornote margin10"&gt;Your comment was unable to be posted at this time. You may try after sometime.&lt;/li&gt;'); } //bindPostCommentHandler(); } }); return false; }); } $(document).ready(function() { bindPostCommentHandler(); }); </code></pre> <p><strong>the html part:</strong></p> <pre><code>&lt;!-- comment form for question --&gt; &lt;div class="commentFormWrapper"&gt; {% render_comment_form for question %} &lt;/div&gt; &lt;!-- comment form for answers --&gt; {% for answer in question.answers.all %} &lt;div class="commentFormWrapper"&gt; {% render_comment_form for answer %} &lt;/div&gt; </code></pre> <p><strong>The problem is</strong>, when there is only a single form in a page it works smoothly. With multiple forms its working but sending the request to the server muliple times(grows in multiples). </p> <p>Also, it would be better to dynamically insert/remove forms. But if I add the html for forms manually, I'll miss out csrf tokens and timestamp fields in the comment form. Anybody has solutions to these ?</p>

    1. COWhen do you call your bindPostCommentHandler function? Is it perhaps called multiple times?

    2. COI call it once at the page loading time and once when the comment was posted successfully. You ca see that inside $.ajax({...success:function(..){ --here-- }. Is the problem occurring due to html tags class name . Should I use id's instead and then bind.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
