Ok, what im hoping is possible here is that given an input document with some json in it, I was considering creating a schema document using this json and then output it to a string which I can then use as a reference for future validation. (we have a LOT of json passed around in our software, so creating a schema from what we have will allow me to catch in CI when changes have been made so we can review for privacy violations).
I realise this isn't at all what the schema validator tools are for. but it looks like they do create internally the schema, does anyone have any idea how I might be able to do this?
Thanks

I have my data model already defined and implemented. I can very easily write manually the filter to filter out non-authorized results for the user who sent the query (which would be in the style of: "collection.acl.personId": queryPersonId )
My problem is, where and how should I write this "thing" to be as automatic as possible?
I tried to do it with a custom query and a static method, but did not had any luck on both.
Static method con: I don't want to rewrite all my code to use .then(). I want to keep the current chaining.
Custom query: it simply did not worked, even by following the doc.
Ideal the result would be something like
Model.findWithAcl(filters).lean()
Model.findOneWithAcl(filters).lean()
Note that we are using Typescript. The priority would be to have something working, but having the ability to have a working type would be the second priority right after.
Thanks for any help
Casl mongoose gives a very good way of filtering both results (row level) and fields from collections. Note that it also can be used in the front end.
Great package that works very well with auth0 rights.

I am using node.js as a scripting language and I am also using nunjucks as the template engine. I have a weird situation going where some of the data that I retrieve from the MongoDB database is not being printed into document.
As you see hear these are the values that I want to print to the web page
But when you look at the web page, only some of the data has been printed out and the other information is missing.
I console.logged the data to prove that the values are in the database
A weird thing is that if you write the whole object into the code, like so
It will output all the data in one block. That includes the month, the year, and slug property that I am trying to output to the page. Yet, it only does that if I print out the whole object
I found out what was the problem. In my mongoose schema, I did not have the properties listed like slug, month, or date. So when I tried to retrieve data from those properties it did not output them. So If you are having similar problems make sure the properties are declared in your mongoose schema
during the development of my app, i very often add custom and new fields to an existing schema, making the 'old' content in my mongodb 'incompelete' and missing the new fields. this leads sometimes to null content where it's required and it's in my use case very bad.
my question is what command/utility do i need to use to make mongoose validate my old documents, and in potential add those missing fields with pre-defined defaults to the old documents?
i remember reading something about that kind of functionality when i started learning how to use mongoose, but i just can't find it anywhere anymore..
thanks in advance :)

I'm playing around with JaySchema (https://github.com/natesilva/jayschema) for a NodeJS application I'm building using ExpressJS. I was wondering if anyone has created, or knows how to, create custom code that ammends the library to allow "strict" validation... By "strict", I mean that any JSON properties that aren't within the schema itself return an error state for the schema's validation.
If anyone has any insight into this, I'd love to hear from you.
Also, if anyone knows an alternative library (preferably available using NPM) that does offer this option, please let me know.
Thanks!
So after a bit of digging, I figured out the solution.
JaySchema supports JSON Schema's standards (details on JSON Schema Standards Docs found here). Within those standards an "additionalProperties" keyword is defined as exactly what I was looking for (more information found here).
According to the documentation (specifically section 5.4.4.4, and an example in 5.4.4.5), if "additionalProperties" is set to the boolean false, then if properties beyond those defined in the schema are found, validation fails.
Since, as I mentioned above, JaySchema supports this JSON Schema standard, if you add "additionalProperties" at the object level to false, you'll achieve the "strict" validation I was looking for.
If you're interested, you can check out the test I have up on GitHub below:
schema: with "additionalProperty" set to false
test: with an additional property added to cause validation failure
I want to have default values for certain fields in my mongoose models. The trick is I don't want to store these values in the database, but what to add them when the model is initialized.
Please help.
You can define an 'init' middleware function for the schema which runs when a model instance is loaded from the database. That should let you manipulate the instance to add your defaults as needed.
Also see this related question for more details as the docs are pretty spare on this.
Maybe a json file?
Using a require('path/to/json' ) you can acces to it and get the values.
Im actually doing something like that, but using the same JSON SCHEMA wich is build for validation purpose.
