Hi, Does anyone know of a method to validate a DateTime field? I''ve looked at the validation docs and the validates_date / validates_time plug-in but I can''t find a method to validate a value in the format of yyyymmddhhmm. It seems like something that should exist already, so I''d just like to check before I attempt my own version... Cheers, Mark
Hi, please take a look at the parse method at the following site: http://www.ruby-doc.org/core/classes/DateTime.html Peace, -Conrad On 4/9/06, Mark Paxton <mark@paxton.plus.com> wrote:> Hi, > > Does anyone know of a method to validate a DateTime field? > > I''ve looked at the validation docs and the validates_date / > validates_time plug-in but I can''t find a method to validate a value in > the format of yyyymmddhhmm.

It should be reasonably straight forward to add a validates_date_time method to my plugin. Just adapt the validator and regex code for the kind of input you want. http://svn.viney.net.nz/things/rails/plugins/validates_date_time -Jonathan On 4/10/06, Conrad Taylor <conradwt@gmail.com> wrote:> > Hi, please take a look at the parse method at the following site: > > http://www.ruby-doc.org/core/classes/DateTime.html > > Peace, > > -Conrad > > On 4/9/06, Mark Paxton <mark@paxton.plus.com> wrote: > > Hi, > > > > Does anyone know of a method to validate a DateTime field? > > > > I''ve looked at the validation docs and the validates_date / > > validates_time plug-in but I can''t find a method to validate a value in > > the format of yyyymmddhhmm.

Conrad Taylor wrote:> Hi, please take a look at the parse method at the following site: > > http://www.ruby-doc.org/core/classes/DateTime.htmlThanks for the help... Is there a particular reason that validates_date and validates_time doesn''t use the above method for Date and Time? ie. Date.parse(value_before_type_cast.to_s) Rescue { errors.add.... } I''ve messed around with the plugin and got it doing something approaching what I need, but it''s not very tidy yet. My other problem is now that I have date and time on the form in seperate text boxes which are combined to be saved as one DateTime field. Is there a way to validate the input from a form that isn''t a field in the model?

I don''t mind spending a bit of time adding this sort of functionality to the plugin, I''m sure others will find it useful and I will probably need it in a month or so anyway.

I think if you define {attr} and {attr}= methods you can use the validators as normal. Untried though. -Jonathan. -------------- next part -------------- An HTML attachment was scrubbed...

Jonathan, does the validates_time support the :before and :after format? ie. validates_time :office_time, :after => "9am", :before=>"5pm" I tried it in the code, and there is no compilation error, but it failed my unit tests - thanks
Not currently, it will very soon though. I might get time today or tomorrow to implement it. Feel free to send me a patch if you feel so inclined! -Jonathan.
