Media (js/css) collection strategy in Forms has no order dependence concept

[tblanchard@…]

And thus is broken. I have a form with a bunch of fields in it and when collecting the js files to include it mixes up the order and thus core.js ends up loaded later than files that require addEvent and the js load fails. At the end of the day, this mechanism is just half baked and would be better removed entirely so busy developers can just get stuff done and not waste time with it.

For example:

class NewIncidentForm(forms.ModelForm):

place = forms.CharField(widget=EditableMap(options={

'layers': ['google.hybrid', 'google.streets', 'google.physical', 'google.satellite', ],
'default_lat': 39.4421,
'default_lon': -100.0,
'default_zoom': 7,
'geometry': 'point',
}))

when_occurred = forms.DateTimeField(widget=widgets.AdminSplitDateTime())
when_reported = forms.DateTimeField(widget=widgets.AdminSplitDateTime())

class Meta:

model = Incident

class Media:

js = ( '/media/js/core.js',

'/media/js/admin/RelatedObjectLookups.js',
'/media/js/getElementsBySelector.js',
'/media/js/actions.js', )

class Incident(models.Model):

title = models.CharField(max_length=128)
when_occurred = models.DateTimeField()
when_reported = models.DateTimeField()
reporter = models.ForeignKey(User)
place = models.PointField()
notes = models.TextField(max_length=4000)
what_type = models.ForeignKey(IncidentType)

# allow spatial querying
objects = models.GeoManager()

results in this:

<link href="/static/olwidget/css/olwidget.css" type="text/css" media="all" rel="stylesheet" />

<script type="text/javascript" src="/media/js/calendar.js"></script>
<script type="text/javascript" src="/media/js/admin/DateTimeShortcuts.js"></script>
<script type="text/javascript" src="​http://openlayers.org/api/2.8/OpenLayers.js"></script>
<script type="text/javascript" src="/static/olwidget/js/olwidget.js"></script>
<script type="text/javascript" src="​http://maps.google.com/maps?file=api&v=2&key=ABQIAAAAWGazslnMSgtzbIMfXLHIgBS5ci6sQZUkD9hfwKAiXgiJK2N7uxTWbLDcob2apHjRnK6OlA7hReqQaA"></script>
<script type="text/javascript" src="/media/js/core.js"></script>
<script type="text/javascript" src="/media/js/admin/RelatedObjectLookups.js"></script>
<script type="text/javascript" src="/media/js/getElementsBySelector.js"></script>
<script type="text/javascript" src="/media/js/actions.js"></script>

which fails because DateTimeShortcuts requires addEvent which is defined in core.js
