Javascript for the Octopus Environments page to enable/disable all machines in an environment

ConsoleScript.js

var OctoTool = {
	GetEnvironmentMap: function(machineStatus) {
		var machinesByEnv = angular.element($('.octo-group-body.machines')).scope().environments.map(function(el, i) {
			var em = angular.element($('.octo-group-body.machines')).scope().machines[el.Id];

		for (var i=0; i<machinesByEnv.length; i++) {
			values[machinesByEnv[i].EnvironmentId] = machinesByEnv[i].OnlineMachines;
		}
		return values;
	},

	SetMachinesInEnvironment: function(envId, setDisabled) {
		var envmachines = this.GetEnvironmentMap(setDisabled ? 'Online' : 'Disabled');
		if (envId && envmachines[envId]) {
			var octoUrl = window.location.href.substring(0,window.location.href.indexOf('/app#')) + '/api/machines/';
			console.log('Ok, ' + (setDisabled ? 'disabling' : 'enabling') + ' : ' + envmachines[envId].map(function(e){return e.Id;}).join(", "));

	},
	
	EnableMachinesInEnvironment: function(envId) {

	}
};

if (window.location.href.endsWith('/app#/environments')) {
	$('.octo-group-header .tools a[octo-permission=EnvironmentEdit]').each(function(i, a) {
	  var envId = a.href.substring(a.href.lastIndexOf('/')+1);
	  var dis = $('<button onclick="console.log(OctoTool.DisableMachinesInEnvironment(\''+envId+'\'))" class="btn btn-link"></a>').text('Disable All');
	  var en = $('<button onclick="console.log(OctoTool.EnableMachinesInEnvironment(\''+envId+'\'))" class="btn btn-link"></a>').text('Enable All');
	  $(a).before(dis);
	  $(a).before(en);
	});
}

Note: This is really brittle, and a fairly hacky way of solving the problem.

But as they say: if it's stupid and works, it ain't stupid :)
