Ruby on Rails

Somehow I did manage to pass the parameter from the dropdown to controller.

But the problem is here - I am getting it as string.

In Controller:----

class ReportController < ApplicationController

  

  REPORT1         = "type =?", "Box"

  REPORT2         = "action = ? and type =?", "create", "Square"

 def report

   param = params[:audit_report] // How to convert this string to an object or static variable ? Or what is the best way to do it ?

   @report_data              = (Audited::Adapters::ActiveRecord::Audit.where(param))

// If I am passing this param, it comes as a string not as static varaible in this controller.

 end

end

In View :----

<script type="text/javascript">

        function audit_options(selected_audit){

jQuery("#reports").load("/audit_report/report?audit_report=" + selected_audit);  

        }

</script>

<%= select_tag "reports_name", options_for_select([["User1", "REPORT1"], ["User2", "REPORT2"]]), :onchange =>"audit_options(this.value)" %>

<div id="reports">

</div>

Sorry for late reply...

Can't we pass the param through ajax or js ?

yes you can. you have to read on ajax.

I am not adding any form because there is no model for this page. 

Only there is controller and view.

you need to add a form to pass the selected values to the controller.  It doesn't

matter whether you're accessing a model or not.

Hello,

I have a dropdown in the UI. There are many oprions.

How do I send the parameter from the dropdown - the selected value to the controller?

I have tried :-

1. <%= select_tag 'name', options_for_select(@list, :selected) %>

2. <%= select("audit", "value",options_for_select([["User Registration", "USER_REGISTRATION"], ["Download", "USER_REPORT"]], :selected => params[:value]) %>

I am not getting any parameters passed to the controller.

make sure that the select tag above is part of the form you are submitting and that you

are actually submitting to the right action.  A quick look on your code raised no issues.
