Modify find/where attributes

[Steve V]

Is there any way to alter attribute values sent to find_or_create_by,
or where clauses all the time? I have some values that are always in a
specific format, but depending on the datasource they are coming in
from, they can be represented differenty. Some have something
prepended to them, others have differing case. Rather than try to make
sure I catch every instance for all time, I am hoping there's a way to
just do it on the model.

Model.where username: 'prefix\somename'
or
Model.find_or_create_by username: 'a.somename'

would both be modified so that they would just be {username:
'somename'}

Thanks,
Steve

Hey Steve. What you asked really isn't Mongoid's job. So the answer is no, Mongoid doesn't do that. Mongoid simply sets the value of fields that you provide it with.

I suggest creating a custom class to massage the data before it's passed to #where or #find_or_create_by .

Cheers,

Nick
