In a model I have following validates_format_of. Is there an easy way to DRY this up? It seems to be rather repetitive. validates_format_of :expiration_date, :with => /^[0-9]{4}[-][0-9]{2}[-][0-9]{2}$/ validates_format_of :activation_date, :with => /^[0-9]{4}[-][0-9]{2}[-][0-9]{2}$/ validates_format_of :some_oth...

...vented in any ''civilisation'', and the fact that we still have to dirty our minds with this in Rails is something that (sh/c)ould ideally be corrected in Rails (preferably before the release of 1.2 (?)) or in the form of a plugin. A very common scenario in Rails models are: validates_format_of :name, :with => [ only characters that are commonly found in Names, ie: NOT {^%$([]\/><?;* ) ] validates_format_of :email, :with => [ valid email format & characters ] validates_format_of :url, :with => [ valid url format & characters ] valida...

I''ve noticed that validates_format_of will return invalid if the field is nil. Question 1) How should we declare a validation that will validate it with a regex if it is set, but, if the field is not set, just move on Question 2) Why is it done this way? The other validators are only invoked if the field is set . If you want to...

...a "price" field and I''m attempting to validate it and allow some flexibility in the way the user enters it. It''s a numeric field but I want the user to be able to enter dollar signs and commas naturally in the data entry. I''m trying to understand how to use validates_format_of, and I''m not sure what I''m missing. I''m a beginner at regular expressions but I''ve been researching it. I tried an extremely simple case: validates_format_of :price, :with => /^\d$/ If I understand correctly, this validation should only succeed for a si...

I''ve got a regex validation on one of the inputs to my application, a file path. Now these only ever come from trusted users (administrators), but it would still be good to catch the most obvious attempts at directory traversal, etc. I''ve already got a regex that only allows \w then -, . and /. However, I want to stop two dots in a row, so I was wondering how to make the

How should I make it optional? Altering the regex? Bt...
