After much ado about the naming of model adn controllers...
model : Expense
controller : Expenses
route : map.resources :expenses
Here I am using mysql database and created a unique index, since
db:migrated created an id object and made it as primary key. Now in
the
def create
@expense = Expense.new(params[:expense])
if @expense.save
flash[:viola] = 'New expense saved.. be frugal, save during this
bad economy'
redirect_to expenses_path
else
render :action => 'new'
#redirect_to new_expense_path
end
Here I try to save, and if any error, render action =>'new'. When I do
that I get the
Called id for nil, which would mistakenly be 4 -- if you really wanted
the id of nil, use object_id
Extracted source (around line #1):
1: <% form_for @e1 do |er| %>
2: <p>
3: name :<br />
4: <%= er.text_field :name %>
I have the @e1 defined correctly in the controller (how can it work
when I go to the new page directly using localhost:300/expenses/new ).
And the trace :
vendor/rails/actionpack/lib/action_controller/record_identifier.rb:
72:in `dom_id'
vendor/rails/actionpack/lib/action_view/helpers/
record_identification_helper.rb:16:in `dom_id'
vendor/rails/actionpack/lib/action_view/helpers/form_helper.rb:264:in
`apply_form_for_options!'
vendor/rails/actionpack/lib/action_view/helpers/form_helper.rb:248:in
`form_for'
app/views/expenses/new.html.erb:1:in
`_run_erb_47app47views47expenses47new46html46erb'
app/controllers/expenses_controller.rb:18:in `create'
What I don't understand is the form_for works fine when used
initially, or even through the
redirect_to new_expense_path
but not through the action => 'new'
Any help is appreciated......
