DataMapper 1.2.0 not returning error messages

[Paul]

Hi,

I recently upgraded to DataMapper 1.2.0 from 1.1.0 and I am not
getting validation error messages anymore. I still get
DataMapper::Validations::ValidationErrors in my exception but no error
messages are populated.

Any ideas as to why this happens?

Thanks,

Paul

I am using Rails 3.2.0 if it makes a difference.

Seems like in the 1.2.0 version of the datamapper, the parent/children
objects are also validated as well when saving an object. That's why
it was failing validation because one of my parent object was not
valid and no errors messages are shown because of that.

Hi Paul,

I wrote a little helper addressing that problem:

Just include it into you models or into DataMapper::Resource and `my_resource.all_errors` will return a nested hash of all errors in associated dirty objects.
