This seems more like a StackOverflow question...
You can try including the relation, using scope on relation etc as described in https://loopback.io/doc/en/lb3/Include-filter.html#include-with-filters
Unfortunately, this is precisely linked to how the SDK is generated. Maybe does it expose the proper method or did I miss something?
On StackOverflow, I do not have any option to create the new TAG called loopback-sdk-builder. I need 1500 reputation. Here is the question link: https://stackoverflow.com/questions/52274917/how-to-implement-a-nested-query-using-loopback-sdk-builder
Here is my ts code:
this.souscription.find({include: {relation: 'category'} }) // this.userService.getSubscriptions(this.currentUser.id) .subscribe((tableData) => { this.dataSource.data = tableData; });
with Subscription having a BelongTo relation to Category:
{ "name": "Subscription", "base": "PersistedModel", "idInjection": true, "options": { "validateUpsert": true }, "properties": { "subscriptionName": { "type": "string", "required": true }, "subscriptionDesc": { "type": "string", "required": false }, }, "validations": [], "relations": { "category": { "type": "belongsTo", "model": "Category", "foreignKey": "", "options": { "nestRemoting": true } }
tableData value does not contain anything linked to category except the id stored in Subscription...
OK. The problem was coming apparently from one Subscription did not have any id. This is the one I checked. So everything works fine.
This is a final update for possible people asking same things.
Thanks
What type of issue are you creating?
What version of this module are you using?
Write other if any:
Please add a description for your issue:
Hello, Would you please excuse me if my question seems to easy for some. For me this is a nightmare. Let's say I have to models, A and B. A is containing a foreign key from B (relation has many). as, every request is returning an Observable, how would I access a "field" of B ? Let's say I am having an Observable after a Find ''. On each result row, I have the ID of a row in B. I want to access another column of B according to the id I got in my first find ''.
Problem: I cannot include multiple subscribes it seems as this generated hundreds of requests.
Any help is appreciated.
Thanks!
