Hello,
I'm trying to use collection select to implement filtering for my page. The
idea is there are a bunch of posts and I want to implement record filtering
for those.
The first collection box would have parameters like "Date",
"Amount",
"Category" and based on the selection of this a secondary drop down
would
appear and allow the user to make a selection. The records on this page
would be then filtered based on both the selection.
I have been trying out many things and have googled a lot on collection but
I have reached a dead end now. I'm pretty new and just started learning ROR.
You help is much appreciated here.
Thanks in advance.
Note: the code below might be wrong and as of now its not even compiling..
currently it complaints of "remote_function" not defined...
-----------------------------
I have a page that looks like this,
<div class="span8">
<% if @user.spendings.any? %>
<h3> Spendings (<%= @user.spendings.count %>)</h3>
<%= collection_select(:category, :category, Category.all, :id, :name
,
{:prompt => 'Select'})%>
<%= collection_select :event, :filterType, Filters.all, :id, :filterType,
{},
{
:onchange => remote_function(
:url => {:action => "updatelevel", :controller =>
"Spendings", :id =>
1},
:with => "'level_id='+this.value"
)}
%>
<ol class="spendings">
<%= render @spendings %>
</ol>
<%= will_paginate @spendings %>
<% end %>
</div>
