Hello,
I’m brand new to ROR and in general server side programing. I’m a iOS developer who is trying to learn ROR.
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>
