Hello all.

I don’t suppose some enterprising soul with much more skill than me has  
whipped up a “validates\_dateness\_of” (Complete with leap year  
calculations) method for use with all the other validation methods and  
wishes to spread much much joy?

Cheers

Think this is what you’re looking for:  
[http://svn.viney.net.nz/things/rails/plugins/validates\_date\_time](http://svn.viney.net.nz/things/rails/plugins/validates_date_time)  
[http://svn.viney.net.nz/things/rails/plugins/validates\_date\_time](http://svn.viney.net.nz/things/rails/plugins/validates_date_time)

Haven’t used it but seems to do that and more

Yeah, validates\_date\_time will probably do what you’re after. I’d be  
interested in your feedback from using it. Any thoughts? Improvements?  
Problems?

Does it validate both Date and Time together? A datetime field in MySQL  
for example.

Thanks!

At the moment it does date and time separately. That’s simply because  
I haven’t needed to validate a datetime input on a form yet. Feel free  
to write patch if you like!
