Question

How I can clear the cache of relational Backbone? relational backbone remembers the previous values ​​after fetch

Answer 1

Backbone.Relational.store.reset()

Answer 2

Backbone.Relational.store.reset();
models.fetch({
  data: {...},
  reset: true,
  success: function(models) {...}
});

Thanks @jax.

Answer 3

Backbone.Relational.store.reset() removes also registered relations. If you want to clear the cache of stored models only, use this:

Backbone.Relational.store._collections.forEach(function each(collection) {
    collection.reset();
});
