..., using R objects to represent elements of a database system (statements, clauses, operators, functions, fields, tables, etc.). R5 classes have made the development of this package somewhat easier than it would have been in the past (in my view, at least). Then an expression like: query(some_table$some_field)$where(some_table$some_field != NA & some_table$some_other_field %in% c(1, 2, 3)) would generate SQL like: SELECT `database`.`some_table`.`some_field` AS `some_field` WHERE `database`.`some_table`.`some_field` IS NOT NULL AND `database`.`some_table`.`some_other_field` IN (1, 2, 3); The basic f...

...me validations during a migration period, is there a way? I tried to use if, with a static method of one of my models, but the behaviour is something strange It seems that the static method should be in a string to be evaluated. And the order of the elements in the if is counting... :if => (:some_field && ''MyModel.some_static_stuff'' ) -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I''m having a bit of difficulty when testing my models, I''ve read a few times the testing chapter in Agile web development with rails and at http://manuals.rubyonrails.com/read/chapter/27 but i''m still unsure of what I should be testing.

I have a form with about 30+ fields, which the client is wanting to separate into 3 pages/steps - just wondering what is the best way to go about this, specifically remembering data entered, from one page to another, and making sure the various bits of data are validated correclty, error messages outputted etc etc... is there a best practice method for doing this? -- Posted via
