GeoDjango PointField admin visualization

Question

I was wondering how I could change the default PointField visualization (the Openstreetmap) in admin so that I could enter simple latitude/longitude instead of select a point on the map?

I looked at this one Latitude/longitude widget for pointfield? but could not get it working in any way in Django 1.6b4

Thanks

As Bibhas says you can override the widget used for the field, but the simple text input may not be usefull. So here is an example with a full widget that can be used for PointField of geodjango:

class LatLongWidget(forms.MultiWidget):
    """
    A Widget that splits Point input into latitude/longitude text inputs.
    """

    def __init__(self, attrs=None, date_format=None, time_format=None):
        widgets = (forms.TextInput(attrs=attrs),
                   forms.TextInput(attrs=attrs))
        super(LatLongWidget, self).__init__(widgets, attrs)

    def decompress(self, value):
        if value:
            return tuple(value.coords)
        return (None, None)

    def value_from_datadict(self, data, files, name):
        mylat = data[name + '_0']
        mylong = data[name + '_1']

        try:
            point = Point(float(mylat), float(mylong))
        except ValueError:
            return ''

        return point

And now you can override your model Admin:

from django.contrib.gis.db import models as geomodels
class CompanyAdmin(admin.ModelAdmin):
    list_display = ('name', 'approval', 'company_view',)
    list_filter = ('approval',)
    formfield_overrides = {
        geomodels.PointField: {'widget': LatLongWidget},
    }

You can override a widget with another in Django admin. From the documentation -

from django.db import models
from django.contrib import admin

# Import our custom widget and our model from where they're defined
from myapp.widgets import RichTextEditorWidget
from myapp.models import MyModel

class MyModelAdmin(admin.ModelAdmin):
    formfield_overrides = {
        models.TextField: {'widget': RichTextEditorWidget},
    }

This overrides TextField with RichTextEditorWidget. Just find the field type for point field and override it with TextField.
