mongoose-unique-validator is a plugin which adds pre-save validation for unique fields within a Mongoose schema. This makes error handling much easier, since you will get a Mongoose validation error when you attempt to violate a [unique constraint] rather than an E11000 error from MongoDB.

QUESTION
I want to use 'mongoose-unique-validator' for handling Mongo ValidationError more easily. The issue comes when I try to force a ValidationError and it doesn't even enters into my custom error handler. Any other error works properly, but not this one.
I just want the validator to send a response JSON so the client app can see what field is wrong/not unique.

QUESTION
I'm using mongoose and the npm package mongoose-unique-validator for validation.
It worked just fine when plugged into my schema, but I changed the validation from an attribute to another one. And now I am still getting the unique mongo error for that old validation (MongoError 11000) for the email... although I moved it to the username, as if the validators from before was not removed and not properly updated.

...ANSWER
Answered 2020-Nov-01 at 15:10Mongoose supports nested populating (see in the docs: https://mongoosejs.com/docs/populate.html#deep-populate). Note that you have to specify your model name of post schema where I´ve put the "post-model-name" placeholder.
So you could try something like this:

QUESTION
I'm currently receiving a validation error when trying to save my object to MongoDB using Mongoose/Joigoose. The basic gist of the schema is that of a simple Group object with a reference to a parent Group's ObjectId (parent_group).
Here's the error:
ValidationError: parent_group: Validator failed for path 'parent_group' with value '5f32d6c58d0c4a080c48bc79'
The code for my Group schema definition looks like this:
...ANSWER
Answered 2020-Aug-16 at 19:47The reason my ObjectId was failing validation is joigoose adds joi validators to the Mongoose schema behind the scenes. Without looking into it too deeply, my understanding is that when joi validates the ObjectId as a string, it passes; after Mongoose converts the ObjectId to an object rather than a string (as the joi validator was expecting), that's where the added validator fails.
Since adding joi validators to Mongoose schema is not a functionality that I want (I am just using joigoose to consolidate schemas), as a quick-and-dirty fix, I commented that section out of joigoose directly in my local copy of it. I am currently using patch-package to maintain this patch in my application.
