create button and open scooby in new window

[grantgeorge]

Proposed fix for #272

I don't know of a way to open a new window within the django admin.py. This hack opens Scooby in a new window while the save functionality is fired.

My concern is that there's potential for a race condition where the new window fetches the location data before it can be saved.

Perhaps I can test this in a stage environment but I'll have to spend some time getting acquainted with stage. @simonw is it possible for me to get setup in stage?

Sorry for not reviewing this sooner!

The way you have this working at the moment affects all of the admin pages - for example here's what I'm seeing on http://0.0.0.0:3000/admin/auth/group/11/change/

To avoid this, one way could be to create a brand new template called admin/change_form_location.html that looks something like this:

{% extends "admin/change_form.html" %}
{% block admin_change_form_document_ready %}
{{ block.super }}
<script>
function onClickSaveOpenScooby(element, locationId) {
    window.open('https://help.vaccinateca.com/call/?location_id=' + locationId, '_blank');
}
</script>
{% endblock %}

{% block submit_buttons_bottom %}
{% load admin_modify %}
    <input 
        onclick="onClickSaveOpenScooby(this, ({{ location_id }}))"
        type="submit"
        value="Save and open Scooby"
        style="margin-bottom: 15px;"
    >
{% submit_row %}
{% endblock %}

Then add the following to the LocationAdmin class:

    change_form_template = "admin/change_form_location.html"

@simonw circling back to this now, thanks for the feedback! I'll take a look at that and test on other admin pages :)
