hi, i was working my way through the LB4 tutorial and got stuck when this error started getting thrown when running npm run build / npm run migrate

Migrating schemas (alter existing schema) Cannot migrate database schema Error: Cannot migrate models not attached to this datasource: TodoList Todo TodoListImage Note at /Users/~/~/code/~/api-test/node_modules/loopback-datasource-juggler/lib/datasource.js:1146:12

Tried reverting to earlier commits, destroying the db, etc but to no avail - any ideas?

debugging the connector inside lib/datasource seems to suggest it is finding the postgresql connector, but the models are not assigned to it

@wildtangent
previously it had worked, while using the same project so something has gone wrong along the way, subsequent to the original migrations being run
:(
DB is postgres, running on docker, nothing fancy

hi guys, do you have any guide/tutorial to learn more about loopback? I'm just starting out and there are not many tutorials I can find online, and most of them is just using the cli to generate code, it doesn't help me to understand and use the framework, is there any tutorial that not only use the cli but actually write some new code? Thank you so much for your time!

@dangchinh2501_gitlab, here is a YouTube video created by one of our maintainers: https://www.youtube.com/watch?v=cgBCRY169qg&feature=youtu.be. It explains pretty well about the framework.
Here is a list of tutorials: https://loopback.io/doc/en/lb4/Tutorials.html. Hope can help you started.
For further questions, please join our Slack community: https://join.slack.com/t/loopbackio/shared_invite/zt-8lbow73r-SKAKz61Vdao~_rGf91pcsw. Thanks!

Hi everyone,
I am working on creating dynamic models and repositories in lb4. I came across this issue:

'BookModel' refers to a value, but is being used as a type here. Did you mean 'typeof BookModel'. in
'''
const DynamicRepositoryClass = defineCrudRepositoryClass<
BookModel, // issue is here
typeof BookModel.prototype.id,
{}

>(BookModel);

'''
But if typeof is used I get an error as follows:

Type 'DynamicModelCtor<typeof Entity, { id: number; title?: string | undefined; }>' does not satisfy the constraint 'Entity'.

I used the Model definitions as given in the documentation https://loopback.io/doc/en/lb4/Dynamic-models-repositories-controllers.html#defining-a-datasource
'''
const bookDef = new ModelDefinition({
name: 'book',
properties: {
....
},
},
title: {
},
settings: {
idInjection: false,
mysql: {schema: 'test', table: 'BookStore'},
},
});

const BookModel = defineModelClass<typeof Entity, {id: number; title?: string}>(
  Entity,
  bookDef,
);

'''

Please help.

Hello world. In lb3 can we trap errors in a remote call in some middleware?
For e.g. consider there is a model. and we try to create a record via the http api POST /api/Customers with some irrelevant json data...
There would be some output on the console to this reflect this...
what middleware is responsible for that...? And how do I put my middleware before it?
arun.jayapal
@deostroll
Okay. never mind. I found the answer.

Hello Community
I posted a question related to an issue I am facing with postgres connector here: https://groups.google.com/g/loopbackjs/c/vY3ykgBgH3Q/m/MIb3Gqq3AAAJ. Can I assume the community is fairly active to get a response ? Just trying to figure this thing out asap.
