Expose remote methods to the nested model

[konst...@bodnia.net]

Hi everyone!

I'm trying to have a remote method described for a specific model exposed as the parent's method nested call (if i'm saying this correctly)

Let's say I have two models:

parent.json:

{ "name": "Parent", "relations": { "model": { "type": "hasMany", "model": "Child" } } }

and child.json

{ "name": "Child", "relations": { "model": { "type": "belongsTo", "model": "Parent", "foreignKey": "parentId", "options": { "nestRemoting": true } } }, "methods": { "prototype.approve": { "accepts": [], "description": "Approves child", "http": [ { "path": "approve", "verb": "put" } ], "returns": { "arg": "data", "type": "Child", "root": true } } } }

That's the setup.

Explorer shows me that I have these this method to as the `/Child/{id}/approve` endpoint.

But parent model doesn't have it `/Parent{id}/Child/{id}/approve`.

What's the best practice to achieve this behaviour?

Thanks everyone!

Hi there,

Check https://loopback.io/doc/en/lb3/Nested-queries.html for that.

Additionally, you've given the name "model" to the relation going from Parent to Child. Not sure that's what you want, as it'll give you a URL like this: /Parent/{id}/model/{id}/approve which is different from your example.

Hope it helps, good luck!

Okay, I've found the reason why.

You were partly right, it was the naming problem. But it's not the name of the relation that matters (they don't matter in any case).

It's the name of the method.

Instead of "prototype.approve" you had to name it "prototype.__approve__child". Then loopback will regex it and detect as a nested remote method.

Hi,

A quick question: I have nest APIs for belongsTo as true. How do I reference nested APIs for disabling method or adding ACLs? First level access using prototype.__create__orgGroups for GET /Orgs/{id}/orgGroup works fine. But the Second level nested API access for belongsTo relation using prototype.__create__orgGroups_Orgs or prototype.__create__orgGroups__get__Orgs for GET /Orgs/{id}/orgGroup/Orgs does not work.

Any help with how to access the method name?

Regards,
Ganesh
