  1. POWhy does this ajax request replace all my comments with the newly submitted comment?
    text
    copied!<p>So I have this form which requests a JS call when a comment is submitted:</p> <pre><code>&lt;%= simple_form_for([@video, @video.comments.new], :remote =&gt; true) do |f| %&gt; &lt;%= f.association :comment_title, :collection =&gt; @video.comment_titles, :label =&gt; "Comment Title:", :include_blank =&gt; false %&gt; &lt;%= f.input :body, :label =&gt; false, :placeholder =&gt; "Post a comment." %&gt; &lt;%= f.button :submit, :value =&gt; "Post" %&gt; &lt;% end %&gt; </code></pre> <p>It calls this create action in the comments controller:</p> <pre><code>def create @comment = @video.comments.new(params[:comment].merge({:user_id =&gt; current_user.id})) if @comment.save respond_to do |format| format.html { redirect_to :back } format.js end else respond_to do |format| format.html { redirect_to :back, :alert =&gt; "Unable to add comment." } format.js { render 'fail_create.js.erb' } end end end </code></pre> <p>which renders this create.js.erb file:</p> <pre><code>$(".comment_content").html('&lt;%= escape_javascript(render(@comment)) %&gt;'); $(".comment_form")[0].reset(); </code></pre> <p>The above create.js.erb file renders the comment partial into this file:</p> <pre><code>&lt;% comment_title.comments.each do |comment| %&gt; &lt;div class="comment_content"&gt; &lt;%= render comment %&gt; &lt;/div&gt; &lt;% end %&gt; </code></pre> <p>Why are all of my comments being replaced by the newly submitted comment in this AJAX request?</p> <p>Here's my comment partial:</p> <pre><code>&lt;%= link_to image_tag(comment.user.profile.photo.url(:tiny)), profile_path(comment.user.profile), :class =&gt; "comment_image" %&gt; &lt;div class="textual_comment_content"&gt; &lt;div class="comment_text"&gt; &lt;span class="name_link"&gt; &lt;%= link_to "#{comment.user.name}", profile_path(comment.user.profile), :class =&gt; "normal" %&gt; &lt;/span&gt; &lt;%= comment.body.gsub("'",'&amp;apos;').html_safe %&gt; &lt;/div&gt; &lt;span class="comment_footer"&gt; &lt;ul&gt; &lt;li class="list_style"&gt;&lt;%= time_ago_in_words(comment.created_at) %&gt; ago&lt;/li&gt; &lt;% unless current_user != comment.user %&gt; &lt;li&gt;&lt;%= link_to "Delete", video_comment_path(:video_id =&gt; @video, :id =&gt; comment), :method =&gt; :delete, :class =&gt; "normal" %&gt;&lt;/li&gt; &lt;% end %&gt; &lt;/ul&gt; &lt;/span&gt; &lt;/div&gt; </code></pre>
