Hello- I've been reading and hacking and reading and hacking and getting frustrated cause my Java background never touched this metaprogramming stuff. I was hoping someone out there could help.
Basically I want to use the ActiveRecordValidation on a a tableless *dynamic* model. I've found lots of good stuff on validating tabless models, it's the dynamic part that alludes me. I was hacking around with some code I found here: http://rails.techno-weenie.net/tip/2005/11/19/validate_your_forms_with_a_table_less_model I posted the code from that link below. The dynamic part is: I have questions in the database, these questions have 'name', 'validation', 'errormessage' and some other fields. I display these questions on a page , when they submit, I need to take this collection of questions (with the users answers), and validate them. Therefore my generic-tableless-model needs to take this collection, create instance attributes for each question.name, then call the given validation (question.validation) on the given value (question.answer) and return question.errormessage if the validation fails. (validation and errormessage are comma separated so that multiple validations can be run) Any help/pointers/suggestions are very much appreciated! Thanks- Michael 1 class Contact < ActiveRecord::Base 2 def self.columns() @columns ||= []; end 3 def self.column(name, sql_type = nil, default = nil, null = true) 4 columns << ActiveRecord::ConnectionAdapters::Column.new(name.to_s, default, sql_type.to_s, null) 5 end 6 7 column :name, :string 8 column :city, :string 9 column :state, :string 10 column :phone, :string 11 column :email_address, :string 12 13 validates_presence_of :name, :email_address 14 end _______________________________________________ PDXRuby mailing list [email protected] IRC: #pdx.rb on irc.freenode.net http://lists.pdxruby.org/mailman/listinfo/pdxruby
