Bootstrap Widgets

A simplistic way of rendering dashboard widgets with Bootstrap.

Add this line to your application's Gemfile:

gem 'bootstrap_widgets'

And then execute:

$ bundle

Or install it yourself as:

$ gem install bootstrap_widgets

Require the CSS file in application.css

//= require bootstrap_widgets

Require the JS file in application.js

//= require bootstrap_widgets

Include the Widgets Module in your Application Helper (plus any other model or controller you want to use it in):

module ApplicationHelper
  include BootstrapWidgets
end

Then in your erb views just call the Helper:

<%= widget @some_dashboard_widget %>

A Dashboard Widget can be created by calling:

DasboardWidget.new(title, panel='text', opts={}, data={})

As you can see, only title is required. Panel Type defaults to text, and opts/data are initialized to {}.

Currently the available panel types are: "text", "bar_graph", "line_graph", "donut_graph", "area_graph".

The following helper methods are available to handle data:

widget.add_data_pair(key,value)
widget.remove_data_pair(key, value)

The opts array can take the following custom options:

• row_size ~> The vertical size of the widget (small, medium, large, x-large). The default is medium.

• col_size ~> The horizontal size (number of columns) of the widget (1-5). The default is 1.

• text ~> The text to be displayed at the top of the widget. The default is nothing. If you set text, the recommended size is large or x-large.

• color ~> The color of the array. See below for more details.

  On top of the above options, for any graphs, Morris.js options can be passed as a hash array. You can read more about which ones are available here

  Here is an example hash: { text: 'I want to be the very best', size: 'large', color: 'light-blue', pointFillColors: ["#469ad0"], pointSize: 10, lineWidth: 10 }

Each of Bootstrap's main colours have been mapped to a type that may make more sense. These are listed below, however, you may use the default Bootstrap names.

'primary' => 'primary',
'green' => 'success',
'light-blue' => 'info',
'yellow' => 'warning',
'red' => 'danger'

By using a widget_group and passing an array of widgets, a dashboard is automatically created with Masonry (auto resizing and position dashboard). Number of Columns can be anything, but obvious limits of a screen exist. Columns defaults to 3.

<%= widget_group [widget, widget, widget], num_of_columns=3 %>

On resize, the library redraws the graphs. Due to this, we put up a loading spinner briefly and redraw the graphs in behind this spinner. This allows for a smoother experience.
