Present? and Blank? Are not working anymore

[rmm5t]

Thanks for the report. And just to confirm, this was working as expected with Mongoid 3.0?

Not sure if that's Mongoid 3.1 problem or carrierwave mongoid itself. Today I did bundle update and the test above failed.

I was going to try to write a failing test, but I first just tried this on a project of mine. I cannot reproduce the same problem.

Mongoid 3.0.17 and Mongoid 3.0.22:

>> Mongoid::VERSION
=> "3.0.21"
>> i.file
=> import/file/5116bcdcc2e4dc4647000005/alpha_import.csv
>> i.file.present?
=> true
>> i.file.blank?
=> false
>> i.file.nil?
=> false

Mongoid 3.1.0

>> Mongoid::VERSION
=> "3.1.0"
>> i.file
=> import/file/5116bcdcc2e4dc4647000005/alpha_import.csv
>> i.file.present?
=> true
>> i.file.blank?
=> false
>> i.file.nil?
=> false

@khelll If you could distill this down to a failing spec and submit a pull-request, I'd be happy to look into a potential fix.

Also, what does your Carrierwave configuration look like?

Sorry for the messed up ticket! After digging more into it, I found out that the uploads folder was missing(what a coincidence after updating the gems!).
The test above seems reasonable now as the .present? seems to be looking for the physical file, not the field value. A little bit new to my taste but it explains everything.
I'm closing this ticket now.

Thanks @rmm5t
