Create Model.json file programmatically

[Michael Inthirath]

Hello,

New to Loopback and am scratching my head on how to create a Model definition programmatically and have it generate its model.json file.

I have looked at Instance Instrospection , but I simply want to create a model from already having the definition and not having an instance yet.

 

I have this in my code:

    var newModel = db.createModel(contentType.name, properties, { "base": "PersistedModel", "idInjection": true });
    newModel.setup();
    app.model(newModel);

Which creates the model and it shows up in API explorer and all, but it doesn't create the model.json file. 

1. Is this the proper way to create a Model definition dynamically?
   
2. Is there a way to generate the model.json file or would i have to build that manually? 
   

Thanks.

Does `slc loopback:model` work for you?

Yes through the command line, but is there a built-in API command to create a model.json file from a Model or Model Definition?

Not OOB, but you can use a combination of discovery + require('fs') to do this -- see http://loopback.io/doc/en/lb2/Discovering-models-from-relational-databases.html
