Is is a total Backbone.js noob question. I am working off of the ToDo Backbone.js example trying to build out a fairly simple single app interface. While the todo project is more about user input, this app is more about filtering the data based on the user options (click events).
I am completely new to Backbone.js and Mongoose and have been unable to find a good example of what I am trying to do. I have been able to get my api to pull the data from the MongoDB collection and drop it into the Backbone.js collection which renders it in the app. What I cannot for the life of me figure out how to do is filter that data and re-render the app view. I am trying to filter by the "type" field in the document.
Here is my script:
(I am totally aware of some major refactoring needed, I am just rapid prototyping a concept.)
$(function() {
window.Job = Backbone.Model.extend({
idAttribute: "_id",
defaults: function() {
return {
attachments: false
}
}
});
window.JobsList = Backbone.Collection.extend({
model: Job,
url: '/api/jobs',
leads: function() {
return this.filter(function(job){ return job.get('type') == "Lead"; });
}
});
window.Jobs = new JobsList;
window.JobView = Backbone.View.extend({
tagName: "div",
className: "item",
template: _.template($('#item-template').html()),
initialize: function() {
this.model.bind('change', this.render, this);
this.model.bind('destroy', this.remove, this);
},
render: function() {
$(this.el).html(this.template(this.model.toJSON()));
this.setText();
return this;
},
setText: function() {
var month=new Array();
month[0]="Jan";
month[1]="Feb";
month[2]="Mar";
month[3]="Apr";
month[4]="May";
month[5]="Jun";
month[6]="Jul";
month[7]="Aug";
month[8]="Sep";
month[9]="Oct";
month[10]="Nov";
month[11]="Dec";
var title = this.model.get('title');
var description = this.model.get('description');
var datemonth = this.model.get('datem');
var dateday = this.model.get('dated');
var jobtype = this.model.get('type');
var jobstatus = this.model.get('status');
var amount = this.model.get('amount');
var paymentstatus = this.model.get('paymentstatus')
var type = this.$('.status .jobtype');
var status = this.$('.status .jobstatus');
this.$('.title a').text(title);
this.$('.description').text(description);
this.$('.date .month').text(month[datemonth]);
this.$('.date .day').text(dateday);
type.text(jobtype);
status.text(jobstatus);
if(amount > 0)
this.$('.paymentamount').text(amount)
if(paymentstatus)
this.$('.paymentstatus').text(paymentstatus)
if(jobstatus === 'New') {
status.addClass('new');
} else if (jobstatus === 'Past Due') {
status.addClass('pastdue')
};
if(jobtype === 'Lead') {
type.addClass('lead');
} else if (jobtype === '') {
type.addClass('');
};
},
remove: function() {
$(this.el).remove();
},
clear: function() {
this.model.destroy();
}
});
window.AppView = Backbone.View.extend({
el: $("#main"),
events: {
"click #leads .highlight" : "filterLeads"
},
initialize: function() {
Jobs.bind('add', this.addOne, this);
Jobs.bind('reset', this.addAll, this);
Jobs.bind('all', this.render, this);
Jobs.fetch();
},
addOne: function(job) {
var view = new JobView({model: job});
this.$("#activitystream").append(view.render().el);
},
addAll: function() {
Jobs.each(this.addOne);
},
filterLeads: function() {
// left here, this event fires but i need to figure out how to filter the activity list.
}
});
window.App = new AppView;
});
