adding a custom angular validator

Fun validator, check if an exercise is one of the big 3:

app.directive "compoundExercise", ->
  restrict: "A"
  require: "ngModel"
  link: (scope, element, attrs, ctrl) ->
    exercises = ["Squat", "Deadlift", "Bench Press"]
    ctrl.$formatters.push (value) ->
      haveX = value in exercises
      ctrl.$setValidity("compoundExercise", haveX)
      return value

    ctrl.$parsers.push (value) ->
      haveX = value in exercises
      ctrl.$setValidity("compoundExercise", haveX)
      return if haveX then value else null

If the field is not valid, then myForm.myFieldName.$error.compoundExercise will be true
Checking if the field is valid:

myForm.myFieldName.$valid

directive with controller in angular

Been trying to get a directive to use a controller method. I had this:

app.directive "myDirective", ->
  restrict: "A"
  controller: ($scope) ->
    sayHello: ->
      alert "Hello"
  template: '<div><a ng-click="sayHello()">Say hello</a></div>'

And it wouldn’t react. The problem was that the method had to be dined on the scope:

app.directive "myDirective", ->
  restrict: "A"
  controller: ($scope) ->
    $scope.sayHello = ->
      alert "Hello"
  template: '<div><a ng-click="sayHello()">Say hello</a></div>'

calling a builtin filter from another angular filter

I needed to call dateFilter from one of my filters. This is how I’ve done it:

app.filter "myCustomFilter", ["dateFilter", (dateFilter) ->
  (input) ->
    # call dateFilter with whatever args
]
