How to get model of entity by id in client js ?

[tothewine]

 var entity = {scope:"Call", id:"12a4c6b8ff8ad5c"};
 var model = ??????; // what do I put here ? 

some js code uses something like the following, but I do not understand if/where the id is passed

this.getModelFactory().create(entity.scope, function (model) {
   // ....
}); 

I think I need to trigger the GET api call for that entity somehow

[yuri]

this.getModelFactory().create('MyEntityType', function (model) {
     model.id = someId;
     model.fetch().then(function () {
           console.log(model); // it's fetched
     }.bind(this));
});

Thanks! Now I understand that. I hope this thread becomes canonical documentation.

Could you also tell me how waiting works? Like the last parameter of createView and this.wait.
What do they do exactly and how are they used?

There gonna be a documentation about waiting.

The problem is that sometimes we need to run some async code before view is rendered. By default a view is rendered after setup method is executed and all views created w/ createView method are loaded. The most rough way is to use wait function with a boolean argument.

setup: function () {
    this.wait(true); // start waiting
    this.model.fetch().then(function () {
          // do something if needed
          this.wait(false); // stop waiting
    }.bind(this));
}

In the doc it will be described how to use promises for waiting.

Wait argument in createView is not recommended to use.

What document are you talking about? Please give a link.

It was upcoming, I'm unsure if it is written yet

yuri I still have a doubt... are client-side models cached? What if I want to obtain a model instance without doing a server synchronization (avoiding the additional GET request) ?
