Django: Point not passing from ModelForm clean to Model clean

Question

I have an Occurrence model that I am putting as TabularInline on the admin page of another model. It has a PointField and a PolygonField, of which at least one must exist.

Here is part of the model:

class Occurrence(models.Model):
    name = models.CharField(max_length=254)
    location = models.PointField(null=True, blank=True)
    bounding_polygon = models.PolygonField(null=True, blank=True)

    def clean(self):
        # Checks if at least one of the spatial fields is filled in
        if not self.location and not self.bounding_polygon:
            raise ValidationError('At least one of the spatial fields (point or polygon) is required.')

In the TabularInline I wanted to put the name and location but when I add new rows the map of the location does not appear. To get around this problem, I used a form where you can enter the latitude and longitude, which is then converted to the Point of location.

Here is my form:

class OccurrenceForm(forms.ModelForm):
    latitude = forms.FloatField(
        min_value=-90,
        max_value=90,
        required=False,
        help_text="Enter coordinates as an alternative to selecting a point on the map."
    )
    longitude = forms.FloatField(
        min_value=-180,
        max_value=180,
        required=False,
    )

    class Meta(object):
        model = Occurrence
        exclude = []

    def __init__(self, *args, **kwargs):
        super(OccurrenceForm, self).__init__(*args, **kwargs)
        coordinates = self.initial.get("location", None)
        if isinstance(coordinates, Point):
            self.initial["longitude"], self.initial["latitude"] = coordinates.tuple

    def clean(self):
        data = super(OccurrenceForm, self).clean()
        #if "latitude" in self.changed_data or "longitude" in self.changed_data:
        lat, lng = data.pop("latitude", None), data.pop("longitude", None)
        if lat and lng:
            data["location"] = Point(lng, lat, srid=4326)
        return data

Here is my TabularInline model:

class OccurrencesInline(admin.TabularInline):
    model = Occurrence
    fields = ('name', 'latitude', 'longitude')
    show_change_link = True
    extra = 1
    form = OccurrenceForm

However, the Point created for the location in the ModelForm is not passed to the Model clean. I have tested this same ModelForm without being in a TabularInline and it works without problems.

Does anyone have any idea why this happens?

Answer 1

I'd say that Orion would allow Context Providers using HTTPS endpoints the same way as with subscriptions, as the code is the same (i.e. the code to deal with outcoming requests is shared between notification logic and request forwarding logic).

Could you check and tell us if it works (as comment to this answer), please? :)

EDIT: the test cases included in this PR assure that HTTPS CPrs are working.
