POBackbone-Relational related models not being created
text
Body
copied!<p>I'm trying to create a nested, relational backbone project but I'm really struggling. The rough idea of what I'm trying to do is shown below but I was under the impression upon calling fetch() on Client, a number of bookings would automatically be created based on the bookings being returned as JSON.</p> <p>The format of my JSON can be seen beneath the outline of the MVC:</p> <pre><code>/**************************************************** /* CLIENT MODEL - Logically the top of the tree /* has a BookingsCollection containing numerous Booking(s) /* Client /* -Bookings [BookingsCollection] /* -Booking [Booking] /* -Booking [Booking] /*****************************************************/ var Client = Backbone.RelationalModel.extend({ urlRoot: '/URL-THAT-RETURNS-JSON/', relations: [ { type: Backbone.HasMany, key: 'Booking', relatedModel: 'Booking', collectionType: 'BookingsCollection' } ], parse: function (response) { }, initialize: function (options) { console.log(this, 'Initialized'); } }); var Booking = Backbone.RelationalModel.extend({ initialize: function (options) { console.log(this, 'Initialized'); } }); var BookingsCollection = Backbone.Collection.extend({ model: Booking }); </code></pre> <p><img src="https://i.stack.imgur.com/f3owB.jpg" alt="Approximate JSON being returned"></p> <p>Any help outlining what I'm doing wrong would be massively appreciated.</p> <p>Thanks</p> <p>EDIT</p> <p>Thanks for taking the time to post the feedback, it's exactly what I was hoping for.</p> <p>Is it the case that the JSON physically defines the actual attributes of models if you don't go to the effort of setting attributes manually? In other words, if the JSON I get back is as you have suggested above, would Backbone simply create a Client object (with the 4 attributes id, title, firstname & surname) as well as 2 Booking objects (each with 4 attributes and presumably each members of the BookingsCollection)?</p> <p>If this is the case, what is the format for referencing the attributes of each object? When I set up a non-backbone-relational mini-app, I ended up in a situation whereby I could just reference the attributes using Client.Attribute or Booking[0].EventDate for example. I don't seem to be able to do this with the format you have outlined above.</p> <p>Thanks again.</p>
