Why this?

I was searching for some django location field which uses mapbox and I could use in my project. I didn't find anything which suits my needs in 100% and that is why I created this simple django app. My philosopy was simplicity but I wanted to create complete solution for picking location.

Feel free to open issues, make pull request and request some features or instructions. Let me know if you think it is not flexible enought.

Compatibility

For now I tested it only on

• Django 2.2
• Python 3.6.1

Travis and unit tests also on other versions in near future.

Instalation

Using pip: pip install django-mapbox-location-field

Configuration

• Add "mapbox_location_field" to INSTALLED_APPS in your settings file

INSTALLED_APPS += ("mapbox_location_field",)

• Define MAPBOX_KEY in your settings file. This is vulnerable information which has to be passed to frontend, so it can be easily access by user. To ensure your safety, I would recommend using url restrictions and public scopes. More information on linked websites.

MAPBOX_KEY = "pk.eyJ1IjoibWlnaHR5c2hhcmt5IiwiYSI6ImNqd2duaW4wMzBhcWI0M3F1MTRvbHB0dWcifQ.1sDAD43q0ktK1Sr374xGfw"

Usage

• Just create some model with LocationField.

from django.db import models
from mapbox_location_field.models import LocationField

class SomeLocationModel(models.Model):
    location = LocationField()

• Create ModelForm

from django import forms
from .models import Location

class LocationForm(forms.ModelForm):
    class Meta:
        model = Location
        fields = "__all__"

• Then just use it in html view. It can't be simpler! Paste this in your html head:

{% load mapbox_location_field_tags %}
{% location_field_includes %}
{% include_jquery %}

• And this in your body:

   <form method="post">
        {% csrf_token %}
        {{form}}
        <input type="submit" value="submit">
    </form>
{{ form.media }}

• Your form is ready! Start your website and see how it looks. If you want to change something look to the customization section.

Customization

In order to change few things you have to use map_attrs dictionary. Default map_attrs looks like this:

default_map_attrs = {
            "style": "mapbox://styles/mapbox/outdoors-v11",
            "zoom": 13,
            "center": [17.031645, 51.106715],
            "cursor_style": 'pointer',
            "marker_color": "red",
            "rotate": False,
            "geocoder": True,
            "fullscreen_button": True,
            "navigation_buttons": True,
            "track_location_button": True,
            "readonly": True,
            "placeholder": "Pick a location on map below",
        }

To change some values, just pass it when you creates model.

from django.db import models
from mapbox_location_field.models import LocationField

class Location(models.Model):
    location = LocationField(map_attrs={"center": [0,0], "marker_color": "blue"})

map_attrs

• style - <string>, mapbox style url. Read more here.
• zoom - <int>, map's zoom. Read more here.
• center - <list> or <tuple> of <float>s, defaults map's center point in [latitude, longitude]
• cursor_style - <string>, css cursor style. Read more here.
• marker_color - <string> css color property. Read more here and here.
• rotate - <bool>, whether you can rotate map with right mouse click or not.
• geocoder -<bool>, whether geocoder searcher is showed or not.
• fullscreen_button - <bool>, whether fullscreen button is showed or not.
• navigation_buttons - <bool>, whether navigation buttons are showed or not.
• track_location_button - <bool>, whether show my location button is showed or not.
• readonly - <bool>, whether user can type location in text input
• placeholder - <string>, text input's placeholder

bootstrap

MapInput widget is fully compatibile with bootstrap library. I can even recommend to use it with django-bootstrap4 or django-crispy-forms.

Admin interface usage

First create some model with location field like in usage section. Then register it in admin interface like this:

from django.contrib import admin
from .models import Location
from mapbox_location_field.admin import MapAdmin

admin.site.register(Location, MapAdmin)

In example above, Location is name of your model. Everything from customization section also works in admin interface.
