I’ve been following the rails/osx tutorial at
This develops a simple application with expenses and accounts.
Near the end of the tutorial, there is a view which allows expenses to
be added to an account.
This view has the “parent” @account rendered, then iterates throught
@account.expenses to display the existing accounts, then has a form.
<%= start_form_tag :action => ‘record’, :id => @account %>
On <%= date_select 'expense', 'paid_on', :order => [:month, :day, :year] %> to <%= text_field 'expense', 'payable_to', :size => 25 %> in the amount of $<%= text_field 'expense', 'amount', :size => 9 %><%= submit_tag 'Record!' %> <%= end_form_tag %>
Which then calls the record action in the controller:
redirect_to :action => ‘show’, :id => params[:id]
and all is well. Very neat.
Except when you try to validate something in the new expense.
I’ve tried replacing the hand coded expense form with the partial in
/expenses/form (which has the “error_messages_for ‘expense’ line”),
but the validation messages don’t show up. The record is validated,
but the rendering of the error messages (and the nice red lines!)
I would be grateful for help! I wonder if it’s due to the page being
unable to find the expenses instance…
Thanks very much
