plugins for admin?

[geomajor56]

I'm using django-leaflet for admin only right now and I'd like to have a plugin like Leaflet.Coordinates available for adding points.
My programming skills are limited, but I'd like to try to add plugin functionality to the admin site. Needless to say, I have no idea where to start. Could you point me to an example? It would be great if I could contribute something.

Thanks for considering to contribute :)

Sorry for the delay. It looks like the guyz at Makina Corpus are busy those days :)

Regarding the inclusion of custom script in forms, you can try this (untested):

LEAFLET_CONFIG = {
    'PLUGINS': {
        'forms': {
            'js': ['vendors/Leaflet.Coordinates.js', 'yourapp/script.js']
            'auto-include': True
        }
     }
}

In script.js:

$(window).on('map:init', function (e) {
    var detail = e.originalEvent ?
                 e.originalEvent.detail : e.detail;
    ...
    // Play with Leaflet.Coordinates
    L.marker([50.5, 30.5]).addTo(detail.map);
    ...

    // Optional specific behaviour for particular field
    map.on('map:loadfield', function (ev) {
        ...
        // Customize map for field
        console.log(ev.field, ev.fieldid);
        ...
    });
});

Good luck!

Any news to share ?

Hi !

This works indeed.

But is there a way to load only specific plugins for specific fields ?

Here I'm trying to display the other features around the edited feature in the admin widget (I intend to allow to snap to those other features). I managed to create a geojson overlayer layer by creating a custom plugin.

LEAFLET_CONFIG = {
    'PLUGINS': {
        'myoverlay': {
                'js': ['/static/leaflet-layers/myoverlay.js'],
                'auto-include': False,
        },
     }
}

But I can't find how to add that plugin to a specific widget. It seems the only way is to add the plugin to

LEAFLET_CONFIG = {
    'PLUGINS': {
        'forms': {
                'js': ['/static/leaflet-layers/myoverlay.js'],
                'auto-include': True,
        },
     }
}

This results in adding the layer in all my widgets. But that overlay only makes sense in a specific field !

I was expecting something like :

class MyModel( models.Model ):
    geom = leafletmodels.Geometry( plugins='myoverlay' )

or the ability to define plugins in LeafletWidget (so that I could override my widgets).

Is this possible ?

Thanks !

Is this possible ?

It is not impossible, but not available out of the box :(

When you say type of field, you mean geometry type?

I am trying to load plugin as it's present in the doc but no result. I want to load the same plugin Leaflet.Coordinates in my admin LeafletgeoAdmin widget.
Apparently JS or CS files are not loaded whereas I put leaflet_tags in the leaflet/admin/widget

Sorry, I should miss something but I don't know what ?
Please could you explain step by step ?

thanks a lot for your share
Best

well done, I fix my trouble by using 'forms' otherwise the 'name of the coordinate plugins'
I had insert the js code in the admin widget by using window.event

sorry for the noise
bye !

this issue is currently giving me grief, and after much work porting mapentity to python 3 and django 1.9 it feels pretty irritating to be stumped by admin templating of a JS library plugins.

Could we get some clear direction as to either the 'right way' to solve this, or acknowledgement that this is indeed a missing feature?

[techdragon]

Ok, I've found the cause of all the trouble.

The media method is 'naive', it explicitly passes the base leaflet JavaScript, plus the JavaScript and CSS defined in _form_js and _form_css which are created in leaflet/__init__.py and used to build the 'forms' plugin and added to the plugin dictionary.

I don't have a PR handy at the moment, but I do have working code. Which I am using with a custom template that overrides the callback block in order to hook into the map creation callback.

I'll try and find time to fork the repo and write a PR.

Great!

[...] it feels pretty irritating [...] Could we get some clear direction [...]

I completely understand, and feel sorry for that.

As I said ealier and elsewhere, I cannot maintain this library anymore. I wrote it while I was working at makina corpus, and haven't used it since I left. The new team seems pretty busy and it looks like they can't take time to review/comment/help...
