Double updating child model causes error

[WildEgo]

Hey guys I've just crashed face first into a problem when trying to update a child model more than once. It looks like on the second attempt of me updating a model this seems to be happening TypeError: Cannot redefine property: _fromResource, has anyone ran into this before and if so how did u solve it?

Best regards, Luis Bizarro.

You might have trouble re-using the model, yes. Currently I overwrite the model instance with the response of the update, see below.

The backend might do something to the model when saving, so it is a good idea to keep backend and frontend in sync anyway.

new Task(this.task)
  .save()
  .then(task => {
    this.task = task;
  })
  .catch(error => {
    // ...
  });

I have never gotten the "Cannot redefine property" error with this. This of course assumes the backend returns the saved model.

@WildEgo Has the comment helped you fix your problem? Can we close this issue?

Today ran into a similar problem. Only the first call of patch() (and save() as well) is successful, any further attempt to call save() or patch() fails with exception.

  async created() {
    this.user = await User.find(2)
  },

// console
$vm0.user.settingsIsDark = false  // false
$vm0.user.patch()  // Promise {<pending>}
$vm0.user.settingsIsDark = true // true
$vm0.user.patch()

Model.js?b77e:89 Uncaught TypeError: Cannot redefine property: _config
    at Function.defineProperty (<anonymous>)
    at User.config (Model.js?b77e:89)
    at User.patch (Model.js?b77e:594)
