I am using datetime\_select to get the date and time from the user to  
execute a certain program (details unrelevant). What I need to do is  
to take certain parts from datetime\_select and manipulate/use them.

## In my view

\<% form\_for(@schtask) do |f| %\>

Scheduled Time  
 \<%=h f.datetime\_select(:schtime, :prompt =\> {:month =\> 'Select month', :day =\> 'Select day', :hour =\> 'Select hour', :minute =\> 'Select minute'}, :start\_year =\> Time.now.year, :order =\> [:month, :day, :year, :hour, :minute], :minute\_step =\> 5)%\>

\<%= f.submit 'Create' %\>

\<% end %\>
## My attempt to get the :day parameter from datetime\_select in the controller

def schedule  
@schtask = Schtask.find(params[:id])  
@day = params[‘schtime(3i)’] #this results in a nil  
#@day = @schtask.schtime.day  
end

Note: schtime parameter is a datetime type in the database

I’d appreciate any help

Thanks,

Have a look in the log to see how it is being passed in the params.  
If you still can’t work it out break into your code using ruby\_debug  
and have a look at params to see what it consists off. I think you  
will find that schtime is inside schtask in the params hash. If you  
have not used ruby\_debug have a look at the rails guide on debugging.

I’ve looked in the log and the parameter passed is schtime(3i). I  
tried doing @day = @schtask.schtime(3i), but the RadRails IDE is not  
reading the parenthese and 3i as part of schtime. I’ll try  
ruby\_debug…
