Where is the right place to write code in a backbone application?

Question

backbone.js

Hello.
Suppose in the project structure, for example, this:
-Models
----users.js
----groups.js
-collections
----users.js
----groups.js
-views
----users.js
-- --groups.js
Is there a code that, when entering data into an input, creates instances of the users model, where is it more correct to write this code? In the model or in the view? Or maybe you can write in a separate file all the interaction with the main objects of the application?

Answer 1

Your models do not exist outside of collections. This means that the logic for their creation (and deletion) lies in the collections.
Of course, the logic for extracting data from the form and passing it to the collection remains in the view.

Answer 2

There is also such a thing as a controller. View calls the controller because its state has changed, the controller decides what to do and what it tells the view to update.
