I have a form which generates a report. The first issue I ran into was trying to create a model to validate some of the entries without saving them....that didnt' work out too well, so I created a report table. I figured uses could save reports for later viewing as a feature.
The form has two field names: report for fields pertaining to the report and :check which are fields not being saved. The check fields have names like: "use_agreed_to_participate" which let me know to use the data in that field to filter by. Here's a snippet:
<div class='reportRow' >
<div class='reportLeftCell'>
Schedule Date
</div>
<div class='reportCenterCell' id='reportScheduleSelects'>
From:
<%= datetime_select('report', 'schedule_date_to') %><br /><br />
<%= datetime_select('report', 'schedule_date_from') %>
</div>
<div class='reportRightCell'>
<%= check_box('check','use_schedule_date', :checked_value => "1", :unchecked_value => "0") %> </div>
</div>
Everything works perfect unless my Report object throws an error on save which brings you back to the form page.
Error snippet:
Showing app/views/admin/_report_form.rhtml where line #31 raised:
undefined method `use_updated_on' for #<HashWithIndifferentAccess:0x3c3df2c>
Extracted source (around line #31):

And finally, liine #39 in new_report:
35 @report = Report.new(@temp)
36 if @report.save
37 redirect_to :action => :show_report, :id => @report[:id]
38 else
39 render :action => 'report'
40 end
I know I'm probably missing something simple here and it has something to do with use_updated_on (and friends) not having a model backend..but is there an elegant way to fix this without hacking rails source or some such?
