具有角色和状态的Ember.js模型架构

Question

I am currently diving into Ember.js. I have started a new project which should handle todo tasks.

However I have some problems in translating the database architecture and/or OOP architecture to an ember model architecture.

What I would like to have is:

A task which has the following attributes:

• id
• title
• state ('open', 'closed')
• editor
• creator
• createdAt
• modifiedAt

The point were I stuck is:

• how to abstract the state (in OOP I would create a struct for this)
• how to abstract the editor/creator thing

I would be glad if anyone would have a suggestion for me since the Ember.js documentation only covers basic use cases and is lack of things like states.

Answer 1

Well actually Ember is OOP, just to mention that first!

Now lets talk about your editor / editor . I would recommend to basically create another model person , and then you could so something like this:

creator: belongsTo('person'),
author: belongsTo('person'),

You don't need an inverse relationship so this will basically just work, as long you don't want to find all task 's one person has created or so.

For the state you basically have three ways:

1. What I recommend is to use another model for this, and use a belongsTo relationship. But this is not a good way if you want to execute different code on different states. But the best if you want to have a dropdown or so to select the state .
2. You could just sent the strings.
3. You could sent integers and have somewhere a mapping to the values. Like an object or an map, to map the integers to the strings.
