Template two models in one view - Backbone/Marionette

问题

I'm trying to use two models in one view, and template using both of them. I'm working with Marionette. Here is me initialization of the view:

main_app_layout.header.show(new APP.Views.HeaderView({
 model: oneModel,
 model2 : twoModel}
));

Here is my view:

APP.Views.HeaderView = Backbone.Marionette.ItemView.extend({

    template : '#view_template',

    className: 'container',


    initialize: function() {
               //This correctly logs the second model
                console.log(this.options.model2);

    }

});

And here is the template:

 <script id="view_template" type="text/template">
        <p>{{twoModel_label}} {{oneModel_data}}</p>
        <p>{{twoModel_label2}} {{oneModel_data2}}</p>
    </script>

It renders everything correctly using the oneModel data, but doesn't render the second, even though it logs it correctly. I'm using Mustache as my templating language.

Can anyone help?

回答1:

You can override the serializeData method on your view and have it return both models' data:


APP.Views.HeaderView = Backbone.Marionette.ItemView.extend({

  // ...

  serializeData: function(){
    return {
      model1: this.model.toJSON(),
      model2: this.options.model2.toJSON()
    };
  }

});

Then your template would look like this:

<script id="view_template" type="text/template">
    <p>{{model1.label}} {{model1.data}}</p>
    <p>{{model2.label}} {{model2.data}}</p>
</script>

try creating a complex model that contains the two models, this new model will have the other two as properties and you can acccess the properties of each one like this answer explains..
