Non-issue regarding lowercase attribute in schema declaration and queries

[daretodave]

When a property is specified to be lower cased in the schema -

...   = new Schema({
  username: {type: String, lowercase: true}
})

Shouldn't the select statements that filter on this property lower-case the input?

                User.findOne({
                    username: "DAVID"
                },

VS. doing this before hand?

                User.findOne({
                    username: username.toLowerCase()
                }

The former find seems more practical when the schema denotes the property is lower-cased.

Additionally insert has this behavior of automatically lower-casing the property.

That's a good suggestion, currently mongoose does not support that but I'd love to add it for a future release

4.10.0 has an option called runSettersOnQuery, for example:

var testSchema = new Schema({
  name: { type: String, lowercase: true },
  num: { type: Number, set: function(v) { return Math.floor(v); } }
}, { runSettersOnQuery: true });

That will run setters when you're querying
