Question

I’m using Mongoose ODM to partially validate models before they are stored to MongoDB.

Is it possible to relax Mongoose schemata so that a given part of the document is not validated? I have tried to the following:

var MySchema = new Schema({
    user_id: { type: Schema.ObjectId, ref: 'User' },
    freeform_data: {},
});

For instance if I set the contents to:

{
   user_id: '123456',
   freeform_data: {
      dataitem1: 'a',
      dataitem2: 'b',
      items: [ 1, 2, 3, 4 ]
   }
}

Then only user_id is stored, which makes perfectly sense security-wise.

How can I disable mongoose’s validation for this field?

I am using this application only for prototyping purposes so I don’t care about security right now (I just want to prototype).

When you modify the contents of a Mixed field like freeform_data, you need to notify Mongoose that you’ve changed its value by calling markModified(path) on the modified document or a subsequent save() call won’t save it.

For example:

user.freeform_data = { foo: 'bar' };
user.markModified('freeform_data');
user.save();
