I am doing some styling in my code where I want to display the time a message is posted on a groups forum in my app. Currenlty posting of every message in this forum works with AJAX functionality implemented via Jquery 1.4.
On including the div tag in my post_message.js.erb file, i find that the message doesn't post on the groups home page( the place where I have all the group specific discussions - a functionality similar to what one would get to see in FB groups ).
The message gets saved in my DB and on refereshing the page I get to see the latest message posted.
The code in post_message.js.erb looks like this:-
$("#new_post").before('<div id ="new_post"><%= escape_javascript(flash.delete(:notice)) %></div>');<!--TO-DO the flash messages aren't yet enabled/working-->
$("#latest_post").prepend("<%= @group_post.message %> by <%= Investor.find(@group_post.post_by).first_name %> <%= distance_of_time_in_words(@group_post.created_at,Time.now) %> ago <br/><br/><hr/>");
$("#new_post")[0].reset();
The above code stops functioning properly when I change the second line to:-
$("#latest_post").prepend("<%= @group_post.message %> by <%= Investor.find(@group_post.post_by).first_name %> <div class ="contentdispgrp"> <%= distance_of_time_in_words(@group_post.created_at,Time.now) %> ago </div><br/><br/><hr/>");
The part of the code corresponding the above in _common.html.erb file( this is a partial view where I have all the html tags and id's which I am eventually using in my .js.erb file) looks like this:-
<table>
<tr>
<%if @current_user.is_an_existing_member_of_group(@investor_group)%>
<%form_for :group_post, @group_post, :url => {:action => :post_message, :id => params[:id]},:html => {:multipart => 'true', :id => 'new_post'} do |f| -%>
Start Discussion:<br><%=f.text_field :message%>
<!--<%=f.file_field :photo%> -->
<%=submit_tag "Post"%></p>
<%end%>
<div id = "latest_post"> </div>
<%for a in @group_all_posts %>
<%= a.message %> by <%= Investor.find(a.post_by).first_name %> <div class ="contentdispgrp" id="style_chck"> <%= distance_of_time_in_words(a.created_at,Time.now) %> ago </div><br/><br/> <hr/>
<%end%>
</tr>
<%end%>
</table>
My post_message method in my groups controller looks like this:-
def post_message
@investor_group = InvestorGroup.find(params[:id])
unless @current_user.is_an_existing_member_of_group(@investor_group)
flash[:notice] = "Please join this group to participate in discussions"
redirect_to :action => :show, :id => @investor_group and return # try to find out what exactly does this command do with return stmnt
else
@group_post = GroupPost.new(params[:group_post])
end
#@group_post = GroupPost.new(params[:group_post])
investor_id = session['investor_id']
@group_post.investor_group_id = @investor_group.id
@group_post.post_by = investor_id
if @group_post.save
flash[:notice] = 'Post was successfully created.'
# redirect_to :action => :show, :id => params[:id] - removed after trying to implement ajax via jquery
else
flash[:notice] = 'Post was not successfully created.'
end
respond_to do |format|
format.html {redirect_to :action => "show", :id => params[:id]}
format.js
end
end
How can I fix this without refreshing the page? I am not sure of what I am doing wrong. Kindly help.
Thanks.
[EDIT]
group.js file code:-
jQuery.ajaxSetup({
'beforeSend' : function(xhr) {
xhr.setRequestHeader("Accept","text/javascript")
}
})
$(document).ready(function(){
$("#new_post").submit(function(){
$.post($(this).attr("action"),$(this).serialize(),null,"script");
return false;
})
})
