Support for JSONB, other nested data structures

[CharlieIGG]

My backend server is using PostgreSQL as a DB. For a specific field in my model, I have a JSONB column.

When I call:

myResourceInstance.update({ 
  jsonField: {stuff: 1234}
})

Then the update reaches my server without this parameter (basically it updates the model instance without any actual changes).

If I instead send some other primitive data type as the value of jsonField then I can see it come through in the request's parameters.

Any ideas how to make this work, without moving away from the JSON:API standard in my server?

I made some specs to reproduce but they passed. Can you post the resource class definition?

This is the real thing:

import resourceLibrary from './library'

class Car extends resourceLibrary.Base {
    static define() {
        this.attributes('year', 'prices')
        this.belongsTo('engine')
        this.belongsTo('make')
        this.belongsTo('model')
    }
}

export default resourceLibrary.createResource(Car);

As a temporary workaround for this I've decided to call

myResourceInstance.update({ 
  jsonField: JSON.stringify({stuff: 1234})
})

And setup a before_save filter on my Rails app that parses that JSON before attempting to save it.

update only sends changed fields to the server. If an attribute is not added in attributes then it won't be sent:

this.attributes('year', 'prices', 'jsonField')

@nicklandgrebe my example didn't match the real-world definition of the resource itself. My bad.

In the real example prices is the JSONB field. And as you can see it was already declared.

If instead of using update you use assignAttributes, what does changedFields return?

[CharlieIGG]

@nicklandgrebe I'll test it out either today or tomorrow and get back to you. 👍

Finally had a chance to test this out.

if I call:

car.assignAttributes({
        prices: update,
})

I get:
