similar to: validates_format_of date

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_other_date, :with =>

Hi all, I''m hoping to stir the Rails pot a little bit here, so please go easy with me ;-) Regular Expressions is the most densely inhumane language construct ever invented 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

Railsters: ActiveRecord''s validation system puts other database systems to shame. However, the newbies might not know how to write a regexp that excludes a match, instead of tests for it. Understand - I''m just asking this question to help them. I have been using Regexps since ''grep'' on Xenix! But the newbies here might not know how to do this:

Hi all, I''ve got a form which accepts 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''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 declare the field mandatory, you add a

I''m using validates_format_of and the validation I want to do works, but I can''t get an error message to be displayed if the data is invalid: validates_format_of :mobile, :with => /\A[\+0-9]+\Z/, :message => " - Wrong" I have another validation some where else that does display the error message: " - Name is too long" validates_length_of :name,

I need a validates_format_of that disallow dots. In the api there is nothing to find about how validates_format_of exatly works. Is there a better documentation or is there something that can tell me howto disallow dots. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups

Been manually testing file column with success except it seems to upload the file before validating it. Also .pdf files (which shouldn''t even validate) crash WEBrick. What am I missing to solve these problems? (apart from a brain!) validates_presence_of :title, :file validates_format_of :file, :with => %r{.(gif|jpg|png)$}i, :message => "File must end with .jpg, .gif or

Often I need to do a one-off validation before Rails has had a chance to convert. For example, a date. Is there a general mechanism to cause validations to run on the raw input or do I have to resort to: private def validate unless attributes_before_type_cast[''date_of_loss''] =~ /^(\d+(-|\/)){2}\d{4}/ errors.add(''date_of_loss'', ''use the

Hi there, I''ve got the following in my model: validates_format_of :postcode, :with => /^([a-zA-Z]{1,2}[0-9]{1,2} [0-9]{1}[a-zA-Z]{2})$/, :message => "is not valid", :if => :postcode ... but it''s not working - it always insists on validation, even if postcode is empty. Basically, the postcode field is optional, but if it''s filled in, I want to

What''s the best way to check a field to ensure it is a valid datetime? I could validates_format_of :with a regular expression for "yyyy-mm-dd hh:mm:ss", but I''m wondering if there is a more direct way to do this. -- Posted via http://www.ruby-forum.com/.

Hi, I''ve put together a simple form that contains among other things a date_select: <%= date_select(:user, :dob, :order => [:day, :month, :year], :start_year => 1900, :end_year => Date.today.year) %> In my controller I have some code to create a user entity from the parameters posted up from the form, like so: parameters:

Dear all, I'm not sure whether this is a bug or not... But some help would be greatly appreciated. I have a dataframe, which I read in using read.xport (from the foriegn library) as the orginal data is in SAS format. 3 columns of this dataset are supposed to be dates, but read.xport doesn't recognise them as dates (all columns are read in as mode numeric). So I load up the date library

Hello, I am trying to read a database exported from SAS. It is form of csv, and the date format reads '02-Feb-99'.

I have files which have columns of data that look like this: DOB 9/27/1964 ... That is, dates in month/day/year format. When variables like DOB are read in, they are converted to factors. So, I wrote this to convert from date to age in years: age<-function(x) {as.numeric(Sys.time()-strptime(as.character(x),format="%m/%d/%Y"))/365.25} This isn't very precise or pretty, but it

Hello All, I've been reading books about R for awhile now and am in the process of replicating the SAS analyses from an old report. I want to be sure that I can do all the things I need to in R before using it in my daily work. So far, I've managed to read in all my data and have done some data manipulation. I'm having trouble with fixing an error in a date variable though, and was
