# Django: Map-Location
Adds a fully-static location field (Leaflet) to manage location-based data without the need for a full-fledged GeoDjango installation. ... when all you need is a visual position chooser.
![screenshot](screenshot.jpg)
## Install
1. Add to your INSTALLED_APPS
```py
INSTALLED_APPS = [
...,
'map_location',
]
```
2. Create Map-Location field
```py
from map_location.fields import LocationField
class Place(models.Model):
location = LocationField('Pos', blank=True, null=True, options={
'map': {
'center': [52.52, 13.40],
'zoom': 12,
},
# 'markerZoom': 18
# 'tileLayer': 'https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png',
# 'tileOptions': {
# attribution: '© <a href="http://www.openstreetmap.org/copyright">OpenStreetMap</a>',
# },
})
```
## Options Paramter
| Key | Info
|-------------|------------------
| map | [Map Options](https://leafletjs.com/reference.html#map-option) (default: `{center: [20, -25], zoom: 2}`)
| markerZoom | Initial zoom scale (on load) if a marker is set. (default: `18`)
| tileLayer | [TileLayer](https://leafletjs.com/reference.html#tilelayer) urlTemplate (default: `"https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png"`)
| tileOptions | [TileLayer Options](https://leafletjs.com/reference.html#tilelayer-option) (default: `{}`)
## Usage
You can access the location by its parts (`place.location.lat` & `place.location.long`) or by its string value (`str(place.location)` or just `place.location`) which will return a comma-separated string (`lat,long`). This string format is also used for database storage (with a precision of 6 digits, or up to 11 cm).
## Example
If you export your location as json, you can use a fully static map:
```py
_JSON_ = {'loc': [place.location.lat, place.location.long]}
```
```html
<script src="/static/leaflet/leaflet.js"></script>
<script src="/static/leaflet/locate/L.Control.Locate.min.js"></script>
<link rel="stylesheet" href="/static/leaflet/leaflet.css" />
<link rel="stylesheet" href="/static/leaflet/locate/L.Control.Locate.css" />
...
<div id="map-id"></div>
...
<script>
const osm = L.tileLayer('https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png');
const map = L.map('map-id', {
layers: [osm],
center: [52.52, 13.40],
zoom: 14,
});
L.control.locate({
returnToPrevBounds: true,
showPopup: false,
}).addTo(map);
L.marker(L.latLng(_JSON_.loc)).addTo(map);
...
</script>
```
