Body
I'm creating a portfolio type site. The project page shows general information about the project and a gallery. I've split it up, so the project page is a Marionette Layout. This layout renders information about the project within its own template and has a gallery region. I want to add a gallery composite view to this region. This will have a large image and a list of thumbnails. Project Layout <pre><code>ProjectView = Backbone.Marionette.Layout.extend template: '#ProjectView' className: 'project__item' events: { 'click .close-project': 'closeProject' 'click #next': 'navigateProject' 'click #prev': 'navigateProject' } regions: { gallery: ".left" } initialize: -> @galleryCollection = new GalleryCollection @model.get('images') onRender: -> @galleryView = new GalleryCompositeView { model: @model, collection: @galleryCollection } @gallery.show @galleryView </code></pre> Gallery CompositeView <pre><code>GalleryCompositeView = Backbone.Marionette.CompositeView.extend template: '#gallery__composite' itemView: GalleryItemView itemViewContainer: '.thumbs' className: 'project__gallery' initialize: -> console.log 'new GalleryCompositeView' </code></pre> Gallery Item View <pre><code>GalleryItemView = Backbone.Marionette.ItemView.extend tagName: 'li' className: 'gallery__item' template: _.template ''' <div class="loading">LOADING</div> <div class="image"></div> ''' initialize: -> console.log 'new GalleryItemView' </code></pre> When I pass both the model and the collection to the composite view I get the error below, but when I pass just the model, it renders fine just without the thumbs. I can't see anything wrong with how I have setup my composite view. Its strange that GalleryCompositeView is being initialised twice. Any direction would be appreciated, thanks. <img src="https://i.imgur.com/jK0n4ti.png" alt="Imgur"> Edit Turns out there where two issues, thanks daivd for pointing out the collection issue, I was just passing in an array or image paths. This was my fix <pre><code> images = [] _.each @model.get('images'), ( el ) -> images.push { src: el } @galleryCollection = new GalleryCollection images </code></pre> The second error was declaring my CompositeView gallery view in my code before the thumb nail views. Changing the order fixed everything. Thanks

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
