Calling .attributes on model object avoid fileds with nil values

Question

When attributes() is called on a Mongoid model object it excludes the fields with nil values, is there a way to get all the fields irrespective of their values?

media = Media.first
media.attributes #=> ignores nil values

Also, FYI this happens when a record is created with only a few attributes, but when we create a record by assigning nil values to the remaining fields explicitly it works fine!

Any help would be highly appreciated!

You can have callback like before_save to assign remaining attributes as nil. This is the default property of mongoid to skip missed attributes — Bijendra, Feb 19 '19 at 08:45

mongoid used to remove empty fields. If you kept some fields empty on insert, mongoid will removes them.

Use media.to_json instead for your case.

Right, to_json returns all the attributes! Thanks for the workaround! – Rajdeep Singh Feb 19 '19 at 09:50

`as_json` works even better, it returns a hash just like `attributes` with all the fields! – Rajdeep Singh Feb 19 '19 at 10:12
