Django地理位置视觉选择器django-map-location
django-map-location是当您只需要一个视觉位置选择器时,无需完整的安装GeoDjango,只需添加一个完全静态的位置字段来管理基于位置的数据。
1.安装
pip install django-map-location
2.添加到您的INSTALLED_APPS
INSTALLED_APPS = [
...,
'map_location',
]
3.创建地图-位置字段
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>',
# },
# 'locate': {
# 'returnToPrevBounds': True,
# 'showPopup': False,
# },
})
选项参数
关键词 | 作用 |
---|---|
map | 地图选项(默认: {center: [20, -25], zoom: 2} ) |
markerZoom | 初始化缩放比例 (负载时) – (默认: 18 ) |
tileLayer | TileLayer urlTemplate (默认: "https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png" ) |
tileOptions | TileLayer选项 (默认: {} ) |
locate | Leaflet.Locate选项(默认: {returnToPrevBounds: true, showPopup: false} ) |
如果将位置导出为 json,则可以使用完全静态的地图:
_JSON_ = {'loc': [place.location.lat, place.location.long]}
<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>
