Mongoose Routes

Description

In this assignment we will integrate menus and sorting into a single application. The goal is provide you a blue print for doing the same thing in your final.

Menus

The menu starts like this:

nav.navbar-default.navbar-fixed-top
    .container-fluid

Inside the div with the class container-fluid we want to put two more divs. The first is the hamburger menu:

.navbar-header
    button(type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#myTarget")
        span.sr-only Toggle navigation
            span.icon-bar
            span.icon-bar
            span.icon-bar
        a.navbar-brand(href="#/") Final

The hamburger menu is boilerplate. It will look the same in all code, with the exception of the last line, navbar-brand which is the title of your application. The data-target can also change, as explained below.

Then we put in our menu, giving it the same id as the data-target from navbar-header. The ID we assign to data-target ties this list of menu items to the hamburger menu. It is what tells bootstrap what to show when the user selects the hamburger menu. The point is that this is the menu that will collapse into the hamburger menu:

#myTarget.collapse.navbar-collapse
    ul.nav.navbar-nav
        li(ng-class="{ active: isActive('/')}")
            a(ng-href='#/') Home
        li(ng-class="{ active: isActive('/edit')}")
            a(ng-href='#/edit') Edit
        li(ng-class="{ active: isActive('/subjects')}")
            a(ng-href='#/subjects') Subjects
        li(ng-class="{ active: isActive('/comments')}")
            a(ng-href='#/comments') Comments
        li(ng-class="{ active: isActive('/about')}")
            a(ng-href='#/about') About

In Chrome, choose the Toggle Device Mode option and select your mobile device, or several mobile devices.

Don't forget to add in the meta data in layout.jade:

html
    head
        meta(charset='utf-8')
        meta(name='description', content='Final by Charlie Calvert for Prog 219 Spring 2015')
        meta(name='viewport', content='width=device-width, initial-scale=1')
        title= title
        etc...

The viewport is essential to make it work on a mobile device. See HTML5 Boilerplate web site for latest and details.

Also add this code to make sure we can see the whole of the jumbotron:

    .elf-container
        div.jumbotron
            h1= title
            p Welcome to #{title}

        #monogoData(data-ng-view="")

And this CSS in JavaScripts/css/Styles.css:

.elf-container {
  border: solid #004b63 thin;
  margin-top: 25px;

Below is my complete for my menus. It's nice to be able to just paste this in, but it is much better if you can see the two main sections:

The Hamburger menu which is the begings with .navbar-header
The menu items, which bigin with the div labeled #myTarget.collapse.navbar-collapse
Notice that the id #myTarget ties the two sections together. If you don't match the two ids, then when you click on the hamburger menu, nothing happens.

extends layout
block content
    nav.navbar-default.navbar-fixed-top
        .container-fluid
            .navbar-header
                button(type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#myTarget")
                    span.sr-only Toggle navigation
                    span.icon-bar
                    span.icon-bar
                    span.icon-bar
                a.navbar-brand(href="#/") Final
            #myTarget.collapse.navbar-collapse
                ul.nav.navbar-nav
                    li(ng-class="{ active: isActive('/')}")
                        a(ng-href='#/') Home
                    li(ng-class="{ active: isActive('/edit')}")
                        a(ng-href='#/edit') Edit
                    li(ng-class="{ active: isActive('/subjects')}")
                        a(ng-href='#/subjects') Subjects
                    li(ng-class="{ active: isActive('/comments')}")
                        a(ng-href='#/comments') Comments
                    li(ng-class="{ active: isActive('/about')}")
                        a(ng-href='#/about') About
    div.jumbotron
        h1= title
        p Welcome to #{title}

    #monogoData(data-ng-view="")

This is the example that I use when I get confused about how to build menus:

Sorting

Arrays have a sort function. For simple arrays, you can just call sort and JavaScript will figure out what to do. If you have an array of object, however, it is often necessary to create a custom callback. The callback allows you to compare two items from the array, returning:

one if the first is larger
Minus 1 if the second is larger
0 if they are equal

Lets assume we have a simple object with an id and name. We place these objects in an array:

    var allNames = [{id: scientist._id, name: scientist.firstName + ' ' + scientist.lastName}];

Here we have only one item in the array, but if we had more items we would want to sort the array by name. We could approach that task like this:

allDataNames.sort(function(scientistA, scientistB) {
    if (scientistA.name > scientistB.name) {
        return 1;
    }
    if (scientistA.name < scientistB.name) {
        return -1;
    }
    // a must be equal to b
    return 0;
});

Routing Comments

This part of this assignment has been moved into a new, separate assignment, called MongooseComments.

This part of this assignment will not be graded. It is included in a new document which is purely informational, it is not an assignment.

Turn it in

Put your work in a folder called either Week11-MongooseRoutes or Week11-MongooseMenuSort, which is a better name for this project. Please specify the name of the folder that contains your work when you submit this assignment.

If your project already contains a solution for the MongooseComments assignment, that is, if it contains a working page that handles comments in routes/comments.js and public/javascript/comment-factory.js, then that is fine. I will give you credit for that work in the MongooseComments assignment.
