ipyleaflet Search Control never successfully searches

I've followed the examples but I can never get the ipyleaflet SearchControl to work in my JupyterLab notebook:

import json
from ipyleaflet import Map, GeoJSON, SearchControl, LayerGroup

m = Map(center=(40, -100), zoom=10)
data = {}
#  fill data as {'layer': GeoDataFrame}

search_space = LayerGroup()

for layer in data:
    search_space.add_layer(
        GeoJSON(data=json.loads(data[layer].to_json(drop_id=True)))
    ) #  `data[layer]` is a geopandas GeoDataFrame

m.add_control(SearchControl(
    position = 'topleft',
    layer = search_space,
))

Even when I grab the same JSON file used in the docs, I still suffer the error that no search term is ever found.

Additionally, I've noticed the map populates with unclickable markers when I attach the controls to map. These markers align with the locations from my data. So something is happening, but it is certainly wrong behavior.

Running ipyleaflet 0.17.0 on Python3.

Solution

  • I had no idea what property_name did because it was undocumented. I created a PR to fix it.
