I am trying to render a backbone collection on a template that is built with mustache.js . The problem is I couldn't get the cid of the model in the template. My code is
<div class="phone span4">
<h5> Phone Appointments</h5>
{{ _.each(slots, function(slot) { }}
{{ if(slot.aptType == "P"){ }}
<h6 cid="{{=slot.cid}}" aptId="{{=slot.aptId}}"> {{=slot.beginTime}} - {{=slot.endTime}} </h6>
{{ } }}
{{ }); }}
</div>
from the above code, I can get the aptId, beginTime and end Time, but not the Cid. How to get the Cid of the model from a collection while rendering it on a template?
and my render method from the view looks like this
render:function(){
var template = _.template($("#slot-display-template").html());
compiledTmp = template({slots: this.collection.toJSON()})
this.$el.append(compiledTmp);
}
Also is there any disadvantage of using cid as the unique identifier of a model ?
Thanks in advance !!!
The cid
is not included by default in the toJSON
output. You will need to override toJSON
in your model definition and include cid
.
toJSON: function() {
var json = Backbone.Model.prototype.toJSON.apply(this, arguments);
json.cid = this.cid;
return json;
}
如果您需要广告解决方案,这也可以:
var params = _.extend({}, this.model.toJSON(), {cid: this.model.cid})
By the way if you don't need to extend behavior of all models you can just add cid
to your model using parse
method. For example you have collection 'Collection'. You can specify model for this collection and override parse
method to attach model's cid
to the response.
var Collection = Backbone.Collection.extend({
model: Model
});
var Model = Backbone.Model.extend({
parse: function(response) {
response.cid = this.cid;
return response;
}
});
So you'll be able to get cid
from model's attributes.
