automatic model creation

[reidlai]

In order to avoid JSON circular reference error when model not found in ArangoDB (see issue 29 below), automatic model creation option should be implemented. This feature can also simplify agile development for fast prototyping.

#29

Please add step to reproduce the issue. Thanks.

@mrbatista
I think he is talking about this issue, e.g.:

In Loopback I have a "Topic" Model.
In ArangoDB the "Topic" Collection is missing.

Now we get this "JSON circular reference error" when trying to query a topic.

An Auto-Creation of the collections ("if collection not exists, then create collection") would be very helpful :)

@mrbatista The automatic model creation is already implemented. So this issue can be closed.
@reidlai I know what your problem is and here is the solution:

Just create a file in database/migrate.js with this content:

var app = require('../server/server');
 
var ds = app.dataSources.arangodb;

ds.automigrate(function() {
  console.log("migrated everything, yeah!")
})

Every connector has a automigrate function which you can call with this command.

Just run it with node database/migrate.js and there you go!
