Basic usage (without Spatial Database)

from django.db import models
from location_field.models.plain import PlainLocationField

class Place(models.Model):

  • Browser autocomplete creates incorrect point

    Browser autocomplete creates incorrect point

    Hi Team, thanks for creating a cool app.

    I have found an issue recently where if browser autocomplete is used then the location field point is incorrect.

    screenshot - good point created on typing typing in - address works

    screenshot - bad point created on autocomplete (Note: the fields in yellow were the browser autocomplete fields) autocomplete - address does not work

    I have <form ... autocomplete="off">... but a lot of browsers ignore this anyway.

    Thanks for your assistance in advance.

    Missing leaflet static files causing errors with ManifestStaticFilesStorage

    When you're using the ManifestStaticFilesStorage, collectstatic fails because it can't find two files. Namely:

    • location_field/images/layers.png
    • location_field/images/layers-2x.png

    The solution would be either to remove those lines from leaflet.css or include the images with the package.

    How to load static files?

    I'm sure I'm missing the obvious here. My form displays a blank space where the map should go, essentially because the static files do not get loaded (or referenced for that matter) in my template. How should I link them? How should I configure the static files?

    Not compatible with Django 2.1

    I did a basic install and added a PlainLocationField to my model, and now the admin crashes with:

    TypeError: render() got an unexpected keyword argument 'renderer'

    It seems on the Django side it is calling:

    widget.render(
            name=self.html_initial_name if only_initial else self.html_name,
            value=self.value(),
            attrs=attrs,
            renderer=self.form.renderer,
        )

    But the LocationWidget doesn't accept renderer as a keyword argument.

  • How to update map marker with current location on the map

    How to update map marker with current location on the map

    Good day,

    We are using the library with this configuration

    LOCATION_FIELD = {
    "map.provider": "openstreetmap",
    "search.provider": "nominatim",
}

    The model is using a PlainLocationField.

    We need to allow the users to use their current location in the map. For this, we implemented this little script

      function getLocation() {
    if ("geolocation" in navigator) {
      navigator.geolocation.getCurrentPosition(showPosition, error);
    } else {
      $("#location-message").show()
    }
  }
  function showPosition(position) {
    $("#id_location").val(position.coords.latitude + "," + position.coords.longitude)
  }
  function error(err) {
    $("#location-message").show()
  }

    it is working fine, the latitude and longitude is automatically updated; however, the marker is not. How may we force the marker to move to the new coordinates?

    We tried editing the coordinates directly and it is not working either; it seems that the marker updates the coordinates field but it does not work in the other way.

    Thank you,

  • LocationField throws AttributeError because value is always None

    LocationField throws AttributeError because value is always None

    Hello there. I have a strange behaviour with the LocationField in my forms.py. I guess i do something wrong, but have no idea what it is (maybe the problem is that i use crispy-forms?)

    I have a Spatial LocationField in my model and added it also to my Create-Form.

    forms.py

    from location_field.forms.spatial import LocationField

class SomeCreateForm(forms.ModelForm):
    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.fields['location'].initial = "2.0,2.0"

        self.helper = FormHelper()
        self.helper.form_tag = False
        self.helper.layout = Layout(
           ...
            LocationField("location"),
            ...
            Submit("create", "Create", css_class="some_class"),
        )

    class Meta:
        model = Place
        fields = (..., 'location', ...)

    Problem:

    When LocationField.clean() is called, the value is always None, which leads to a AttributeError. The initial-value gets propagated to self.initial in my case.

    class LocationField(PlainLocationField):
    def clean(self, value):
        try:
            lat, lng = value.split(',')
            return Point(float(lng), float(lat))
        except ValueError:
            return None

    So as a workaround i created a costum MyLocationField() where i add the initial value directly into the .clean() function. I am looking forward to any kind of help or advice here. Thank you!
