document.save after setting an autopopulated field about mongoose-autopopulate

@naeemshaikh27 what does your schema validation failed error look like?

[naeemshaikh27]

its a cast error for the autopopulated field, I got the result autopopulated and was trying to save after updating the field as just objectId.

Example:
got result as,

company:{
   _id: 'some Object Id'
   name : 'some name',
   admin:'admin name'
  }
});

and now I am trying to save it as:
company: someObjectId';

Now as the schema says, company is type objectId

var schema = new mongoose.Schema({
  company:{
   type: Schema.Types.ObjectId,
   ref: 'companyProfile',
   autopopulate: { select: 'name _id  admin'},
  }
});

it should save, but i get following error-

{ [ValidationError: companyProfile validation failed]
  message: 'companyProfile validation failed',
  name: 'ValidationError',
  errors: 
   { 'company': 
      { [CastError: Cast to ObjectID failed for value "ObjectID,WNËvgÝÛ\o�¦" at path "company"]
        message: 'Cast to ObjectID failed for value "ObjectID,WNË\u0018vgÝÛ\\o�¦" at path "company"',
        name: 'CastError',
        kind: 'ObjectID',
        value: [Object],
        path: 'company',
        reason: [Object] } } }

Try to use mongoose-autoset which will set id from instance which have already been populated.

For your model update property/field definition to

var schema = new mongoose.Schema({
  company:{
   type: Schema.Types.ObjectId,
   ref: 'companyProfile',
   autoset:true,
   autopopulate: { select: 'name admin'},
  }
});

schema.plugin(require('mongoose-autoset'));

After that you dont have to worry about set id each time you have and ref that is already populated.

Hope it helps.
