help with ''error_messages_for''
Greetings,
I''m in the throws of deploying an app on site5, and I''m getting strange
errors. I think I might need to understand how error_messages_for
works.
I get a pretty standard looking error:
"
You have a nil object when you didn''t expect it!
You might have expected an instance of ActiveRecord::Base.
The error occured while evaluating nil.errors

Formating Float ActiveRecord attributes in text inputs
I have AMOUNT field that ActiveRecord maps to Float.
Then I use text_field helper to generate text inputs on forms.
Helper takes model object and attribute name and does not provide any
formatting abilities, thus 2.40 is shown as 2.4 which is fine with
floats but does not look good with currency.
I have worked around this issue by adding amount_f attribute to the
model that returns formatted

Getting the object in fields_for
I''m using the fields_for helper with accepts_nested_attributes_for

Unit testing + instance variables
After *much* digging and playing around, I finally figured out how to
unit test instance variables that are created by actions. It was
more difficult than I expected. It seems like there should have been
a more straight forward way to do this. Can someone enlighten me? A
simplified and somewhat contrived example of what I am current doing:
Thanks.

Serialized object behaves weird
Hi!
I got a class named EinsatzFilter which I serialized to session. Before
saving to session it works afterwards I keep getting the message:
"undefined method `to_s'' for #<Person:0x38c6ab8>". "Person" is a from
ActiveRecord::Base inherited class.
Code:

Active Record, Migration, and Translation
Hi,
I think the columns and table in migration should be able to have an
optional "display_name" set manually. Something like:
create_table :people, {display_name => "Personne"} do |t|
t.column :first_name :string, :display_name => "Prénom".
end
Let me explain my point of view:

How do i switch off error wrapping for a specific field?
Hi, i have some issues with the default rails error wrapping. It wraps
errors in a div with class ''fieldsWithError'', which is not good practice
in my eyes. Adding a class ''error'' to the field would be much nicer.
My solution to the problem: build your own FormBuilder. Funny enough, i
found no (nice) possibility to switch error wrapping off while using the

ActionView::Helpers::FormHelper instance methods should take an object reference rather than an object_name.
Hi
ActionView::Helpers::FormHelper methods (e.g. #text_field,
#check_box...) take object_name as an argument. From this argument
they infer a name that is supposed to contains the reference to the
relevant object.
I can''t see why the FormHelper methods were designed that way.
Compared to simply passing them a reference, the current way seems too
complicated and an invitation to problems

Rails Plugin to Help Debug Views
Hi,
I just released a plugin to help debug views. The plugin makes it easy
to add a button that will popup a new window that displays the
following debug data;
* Request Parameters
* Session Variables
* Flash Variables
* Assigned Template Variables
It was derived from code that traces back to Marten Veldthuis in
Epilog. You can check out webpage and plugin via;
