I was wondering if someone could embarrass me and just post a simple inject->worldmap node example that draws a circle around a location as I can't get it do do that
doesn't the example in the readme work for you ?
I found this example in my node-RED projects. Probably is the same one from the flows page or perhaps with some modification. Anyway, it is quite simple.
[{"id":"8118e0cc.d91e5","type":"tab","label":"Flow 5","disabled":false,"info":""},{"id":"e6ac1fc6.e3157","type":"worldmap","z":"8118e0cc.d91e5","name":"","x":670,"y":200,"wires":[]},{"id":"70f8c8be.5478e8","type":"function","z":"8118e0cc.d91e5","name":"30 meters circle","func":"msg.payload = { lat:51.05, lon:-1.35, name:\"A3090\", radius:30 }\nreturn msg;","outputs":1,"noerr":0,"x":460,"y":200,"wires":[["e6ac1fc6.e3157"]]},{"id":"f5cebbf1.137988","type":"inject","z":"8118e0cc.d91e5","name":"","topic":"","payload":"","payloadType":"str","repeat":"","crontab":"","once":false,"x":290,"y":200,"wires":[["70f8c8be.5478e8"]]}]
I tried this
coverting ths
msg.payload = { name:"Joe", lat:51.05, lon:-1.35 }
to this
I get very confused with JSON but tried sticking quotes around stuff and still doesn't seem to do anything
I know its me but I've not been lucky with what I've tried
The map will not open in the dashboard. As per the worldmap help it is necessary to key ctr+shift+m (in windows)
Shortcut - `⌘⇧m` - ctrl-shift-m to jump to Map.
i know that bit
What I mean is - I can copy and paste your flow into my editor( via normal menu-import-paste from clipboard) tab but nothing appears in the editor
Very stange - not had it happen before
Really not being lucky with one
There is a specific example in the readme about circles...
[{"id":"c0e71a8c.e22e48","type":"inject","z":"dfe4ec36.0a5a5","name":"","topic":"","payload":"{ \"lat\":51.05, \"lon\":-1.35, \"name\":\"A3090\", \"radius\":3000 }","payloadType":"json","repeat":"","crontab":"","once":false,"onceDelay":0.1,"x":170,"y":1180,"wires":[["f22e5b4f.f7bf28"]]},{"id":"f22e5b4f.f7bf28","type":"worldmap","z":"dfe4ec36.0a5a5","name":"","lat":"","lon":"","zoom":"","layer":"","cluster":"","maxage":"","usermenu":"show","layers":"show","panit":"false","x":370,"y":1180,"wires":[]}]
Really strange. The flow TAB name is Flow 5. I tested by importing and it shows up in the editor.
Here is the configuration in the function node. Nothing configured in the worldmap node.
msg.payload = { lat:51.05, lon:-1.35, name:"A3090", radius:30 }
return msg;
I see now... this sems to be the issue. Comparing with Dave´s flow you can see how the JSON is supposed to be . Missing quotes in your inject node. Also missing the radius property on your flow.
{
"lat": 51.05,
"lon": -1.35,
"name": "A3090",
"radius": 3000
}
Tried that - no errors in JSON this time but I think this is where that lat/lon should be but I can't see anything - something must be broken at my end
missing the radius property ?
have you hit inject AFTER the map has connected to the server ? (plus zoom out a little)
top tip the label bottom left is green for connected, red for disconnected/error
I do think I see it, u r hitting the ball,,,yes,,,hole-in-one
#shame
It (of course) works now - thank you
I think I was getting in such a knot with my json syntax original problem and then I forgot that i should PRESS THE BUTTON! was my last error
the worldmap-in node does provide an event when someone connects (and other things) that you could of course use to trigger that automatically if required.
Any hints for using worldmap behind a reverse proxy? I'm struggling with apache and the websockets…
Edit: I did it:
<Location /red/worldmap>
RewriteEngine on
RewriteCond %{HTTP:UPGRADE} ^WebSocket$ [NC]
RewriteCond %{HTTP:CONNECTION} Upgrade$ [NC]
RewriteRule /socket/(.*) ws://127.0.0.1:1880/red/worldmap/socket/$1 [P]
