Working with 2 tables in a Controller

Hi

a) I have 2 tables, namely workplans and timesheets.
b) What I am trying to do is to add a custom link to AS List … OK

c) Then, when I click this link eg ‘transfer2timesheet’, a new record
will then be created in the timesheets table and populated with the
values from the workplan table

d) I added a transfer2timesheet method after the local config block
in workplans controller as follows :-

class WorkplansController < ApplicationController
active_scaffold :workplan do |config|
config.columns
=[:calen_date,:staff,:customer,:category,:work_plan,:no_of_hrs,
:where_work]

config.action_links.add 'transfer2timesheet', :label

=>‘Transfer’, :type => :record, :page => false
end

def transfer2timesheet
newtimesheet=Timesheet.new
newtimesheet=User.current_user.login
sourcetable=Workplan.find(Param[:id]) # this where the 500
error is triggered
newtimesheet.where_work=sourcetable.where_work
newtimesheet.save
end
end

Result : 500 error

e) I have also tried

def transfer2timesheet
newtimesheet=Timesheet.new
newtimesheet=User.current_user.login
newtimesheet.where_work=Workplan.where_work # this where the 500
error is triggered
newtimesheet.save
end
end

Result : 500 error

Any assistance to resolve the error in (d) and (e) is greatly
appreciated.

TIA.

Hi,

sourcetable=Workplan.find(Param[:id])

this where the 500 error is triggered

If you’re trying to use a value in the params hash, the syntax would
be…
Workplan.find(params[:id])

HTH,
Bill

Hi Bill

Thanx for pointing out the typo error !
