Unable to use your connector ( model configuration issue, automigration gives NaN 'cassandra' )

[Orxcle-xx]

Hi guys,

I am trying to use integrate loopback-connector-cassandra with no success.

First issue I stumbled upon is how models should be configured. According to the documentation, they should be configured similar to this:

zipCodes = db.define('zipCodes', {
  state: String,
  zipCode: Number,
  });

But loopback configures them totally differently! The common structure is:

{
  "name": "AppUser",
  "base": "User",
  "idInjection": true,
  "options": {
    "validateUpsert": true
  },
  "properties": {
  },
  "validations": [],
  "relations": {},
  "acls": [],
  "methods": {}
}

How exactly they should be configured?

I also tried to create tables in Cassandra using this code ( I tried both methods autoupdate & automigrate ):

var server = require('./server');
var ds = server.dataSources.cassandra;
var models = []; // will be aplied to all models
ds.autoupdate(models, function(er) {
  if (er) throw er;
  console.log('Loopback tables [' - models - '] created in ', ds.adapter.name);
  ds.disconnect();
});

My datasource name is "cassandra". However, code just prints:

NaN 'cassandra'

Do you have any basic example of fully configured Loopback project with cassandra datastore? I believe it will help a lot.

Thank you in advance.

Best,

Sorry, this one slipped through the cracks. Technically, in the body of the model definition, you'll want to add your properties in the properties collection.

So, in the above example you've given, it would look like this:

{
  "name": "AppUser",
  "base": "User",
  "idInjection": true,
  "options": {
    "validateUpsert": true
  },
  "properties": {
    "state": {
      "type": "string"
    },
    "zipCode": {
      "type": "number"
    }
  },
  "validations": [],
  "relations": {},
  "acls": [],
  "methods": {}
}
