attempt to override the ''tag'' method
I want to override the ''tag'' method in
ActionView::Helpers::TagHelper to do some generalized
error handling similar to the way scaffolding puts a
red border around fields that fail validation.
I''ve created a file lib/rails_patches/tag_helper.rb
which contains the following.
module ActionView
module Helpers
module TagHelper
alias_method :orig_tag, :tag

def update
@question = Question.find(params[:id])
if @question.update_attributes(params[:question])
flash[:notice] = ''Question was successfully updated.''

best practice on making a searchable/filterable list?
Hi, I have many pages that list information (modified from the
scaffolding). I would like to include a box at the top of these pages
that has some search criteria with drop downs, date ranges, etc.
When the user submits, the controller then adds appropriate conditions
to the find method, and the matching records are displayed with the
search form maintaining the users selections.

options_from_collection_for_select - NIL Object
i am kind of desparated
i try with options_from_collection_for_select to get option values, but
it says
You have a nil object when you didn''t expect it!
You might have expected an instance of Array.
The error occured while evaluating nil.inject
but @customers is not empty ->
def get_customer
@customers=Customer.find_all
end
i have tested it and also the attributes "id"

Help: Input of form 1 to hidden field in form 2?
Hi all I''m new to rails an i''m trying to build a step by step form /
process to gather data. For example:
form one:
User enters a 8 digit number
the submit button points to form 2.
form two:
the 8 digit number from form one becomes a hidden field in form 2.
The problem I have is that the entire hash from form 1 is showing up in
form two rather than just the input data.

AJAX call chain and DRY questions
Hey
I have a page with a drop list. When the user selects an option in the
drop I call an action in the controller with ajax. Now, in the
controller, I gather some data from the db, but how do I present these
data in a nice way? I really need to make use of the html helpers, but
these clearly are not available in the controller. How do I output the
array that I have gathered?
