Added two charts for Number of Volumes and Total Volume Storage quotas on Python launch instance modal when cinder is enabled. The charts reflect the volume usage of the new instances to be created as the user changes the configuration on the modal.

/*
|
|
Used for animating and displaying quota information on forms using
|
|
D3js progress bars. Also used for displaying flavor details on modal-
|
|
dialogs.
|
|
|
|
Usage:
|
|
In order to have progress bars that work with this, you need to have a
|
|
DOM structure like this in your Django template:
|
|
|
|
<div id="your_progress_bar_id" class="quota_bar">
|
|
</div>
|
|
|
|
With this progress bar, you then need to add some data- HTML attributes
|
|
to the div #your_progress_bar_id. The available data- attributes are:
|
|
|
|
data-quota-used="integer" REQUIRED
|
|
Integer representing the total number used by the user.
|
|
|
|
data-quota-limit="integer" REQUIRED
|
|
Integer representing the total quota limit the user has. Note this IS
|
|
NOT the amount remaining they can use, but the total original quota.
|
|
|
|
ONE OF THE THREE ATTRIBUTES BELOW IS REQUIRED:
|
|
|
|
data-progress-indicator-step-by="integer" OPTIONAL
|
|
Indicates the numeric unit the quota JavaScript should automatically
|
|
animate this progress bar by on load. Can be used with the other
|
|
data- attributes.
|
|
|
|
A good use-case here is when you have a modal dialog to create ONE
|
|
volume, and you have a progress bar for volumes, but there are no
|
|
form elements that represent that number (as it is not settable by
|
|
the user.)
|
|
|
|
data-progress-indicator-for="html_id_of_form_input"
|
|
Tells the quota JavaScript which form element on this page is tied to
|
|
this progress indicator. If this form element is an input, it will
|
|
automatically fire on "keyup" in that form field, and change this
|
|
progress bar to denote the numeric change.
|
|
|
|
data-progress-indicator-flavor
|
|
This attribute is used to tell this quota JavaScript that this
|
|
progress bar is controller by an instance flavor select form element.
|
|
This attribute takes no value, but is used and configured
|
|
automatically by this script to update when a new flavor is chosen
|
|
by the end-user.
