django-leaflet allows you to use Leaflet in your Django projects.
It embeds Leaflet in version 0.5.1.
pip install django-leaflet- Add
leafletto yourINSTALLED_APPS Add the HTML header:
{% load leaflet_tags %} <head> ... {% leaflet_js %} {% leaflet_css %} </head>Add the map in your page, providing a name:
... <body> ... {% leaflet_map "yourmap" %} ... </body>- Your maps shows up!
You can use the Leaflet API as usual in the map initialization callback:
<script type="text/javascript">
function yourmapInit(map, bounds) {
...
L.marker([50.5, 30.5]).addTo(map);
...
}
</script><style>
.leaflet-container { /* all maps */
width: 600px;
height: 400px;
}
#specialbigmap {
height: 800px;
}
</style>In order to configure django-leaflet, just add a new section in your settings:
LEAFLET_CONFIG = {
# conf here
}You can configure a global spatial extent for your maps, that will automatically center your maps, restrict panning and add reset view and scale controls. (See advanced usage to tweak that.):
'SPATIAL_EXTENT': (5.0, 44.0, 7.5, 46)To globally add a tiles layer to your maps:
'TILES_URL': 'http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png'This setting can also be a list of tuples (name, url) ! A layer switcher will then be added automatically.
Disable scale control with km and miles:
'SCALE': FalseShows a small map in the corner which shows the same as the main map with a set zoom offset:
'MINIMAP': TrueBy default it shows the tiles of the first layer in the list.
callback: javascript function name for initialization callback. (Default:name + Init). Example:{% leaflet_map "yourmap" callback="window.customMap" %}fixextent: control if map initial view shoud be set to extent setting. (Default:True). Setting fixextent toFalsewill prevent view reset and scale controls to be added.creatediv: control if the leaflet map tags creates a new div or not. (Default:True). Useful to put the javascript code in the header or footer instead of the body of the html document. If used, do not forget to create the div manually.
It is possible to setup the map spatial reference in LEAFLET_CONFIG:
'SRID': 2154 # See http://spatialreference.orgAdditional parameter is required to compute scale levels : the tiles extent in local projection:
'TILES_EXTENT': [700000, 6325197, 1060000, 6617738],For more information, have a look at this example.
By default, Django will try to load the spatial reference from your static files at "proj4js/{{ srid }}.js". If it fails, it will eventually rely on spatialreference.org.
