I am just getting started with Rails, don''t know any Ruby, and don''t quite even get object oriented programming yet. I have tweaked my schema to The Rails Way and have generated a bit of scaffolding. I am trying to create a new Part, which references a PartName and a PartNumber. I can create a PartNumber on the fly, but the PartName has to exist. I have an inelegant solution

It was working before (as far as I can tell), but I freezed_edge and now... The first time I load this page, it works fine, the second time I get the superclass mismatch, the third time (and any subsequent times ) i get undefined method. I think this means my class is getting loaded twice? my model looks like this: class Quotation < ActiveRecord::Base has_many :price_breaks has_many

What could cause this? >> sdfl=PartNumber.find_by_part_number("1111111") => #<PartNumber:0xb78fc744 @attributes={"id"=>"11601", "part_number"=>"1111111"}> >> sdfl=PartNumber.find_or_create_by_part_number("1111111") NoMethodError: undefined method `find_or_create_by_part_number'' for PartNumber:Class

In my controller, I do this to instantiate and populate my Part, PartName and PartNumber objects. def edit @part = Part.find(params[:id], :include => [:part_name, :part_number]) end But in the view, this doesn''t refer to the right object. I somehow need to indicate that the part_name object is a child of the part object. <%= text_field_with_auto_complete :part_name,

I''m getting errors whenever the user chooses, for example, April 31st ( since there is no 31st in April, navicat freaks out ), there MUST be a method that ruby has that would allow me to validate a date before I submit to navicat. I haven''t been able to find anything online about it either, it''s probably something simple, I just can''t figure it out. Thanks
