I have the 2 views for my model. One creates the ul view, the other add the li elements. The views work but they do not update after the destroy function is called. I've tried various ways to bind to the render function, but it is not being called after this.model.destroy(); What am I missing?
var NoteListView = Backbone.View.extend({
tagName:'ul',
className: 'note-group',
initialize:function () {
_.bindAll(this, "render"); // I've tried all these:
this.model.bind("change", this.render, this);
this.model.bind("destroy", this.render, this);
this.model.bind("reset", this.render, this);
this.model.bind('change', _.bind(this.render, this));
this.model.on('change',this.render,this);
},
render:function (eventName) {
_.each(this.model.models, function (note) {
$(this.el).append(new NoteListItemView({
model:note
}).render().el);
}, this);
return this;
}
});
var NoteListItemView = Backbone.View.extend({
tagName:"li",
className: 'note-item',
template:_.template($('#tpl-note-item').html()),
initizlize:function(){
this.model.on('change',this.render,this);
},
render:function (eventName) {
$(this.el).html(this.template(this.model.toJSON()));
return this;
},
events: {
"click .note-btn-delete": "deleteNote"
},
deleteNote: function(e){
this.model.destroy();
}
});
Edit: here's the Collection:
var NoteCollection = Backbone.Collection.extend({
model:Note,
url:"api.php/notes",
initialize: function (models){
this.filtered = new Backbone.Collection(models);
},
filterByCid: function(id) {
var filtered = _.filter(this.models, function (model) {
if (id==0) return true;
return model.get("contactid") == id;
});
}
});
In the router:
this.noteList = new NoteCollection();
this.noteList.fetch({data:{contactid:id},
success: function (collection){
if (collection.length>0){
$('#note-container').html(new NoteListView({model:collection}).render().el);
}
else {
$('#note-container').html('No notes');
}
}
})
