QUESTION
In my django app I am using Geodjango, django-leaflet and leaflet-ajax. I have a route model with a LineStringField. I want to render that route in a template using a leaflet map. I have tried the following code with other models (those that have a Point field instead). But for any reason this code is not working with the RouteModel. The leaflet map shows nothing. How can I add that route to the "gis" leaflet map
Here is the model definition
...ANSWER
Answered 2021-Jun-08 at 16:35I just found the Issue: I had a duplicate of the route_get_location function in another file. So the this post is a working example of how to represent a Geodjango model using django-leaflet and leaflet-ajax

...ANSWER
Answered 2021-Jun-07 at 08:39The geojsons contain only geometry, so you will need to read each from the array and create a Feature which can be displayed on the map.
QUESTION
I'm new to NetLogo and I have a question that I'm sure is pretty basic. But, I'm not getting over the difficulty.
If anyone can help me overcome this difficulty, I would be very grateful.
I would like from the patch where the turtle is found to consider the 8 neighboring cells in search of the highest pveg value. If it has equally high values, choose 1 of these randomly. Upon finding the highest pveg value of the neighbors, the turtle went there.
I am using the command: max-one-of. I think it serves my purpose. But, I'm making some syntax error that shows the following error: MOVE-TO expected input to be an agent but got NOBODY instead.
Thanks in advance
...ANSWER
Answered 2021-Jun-04 at 08:04The NetLogo dictionary says, max-one-of
needs an agentset and a reporter as input:

QUESTION
Although I have read many similar articles about PointField
and 'NoneType' object error
, I can't figure out how this field should be automatically save according to the latitude and longitude variables I received from the user.
Here is my model:
...ANSWER
Answered 2021-Jun-01 at 16:02Why am I getting the 'NoneType' object error?
Because you defined save
as a @property
. As a result if you use self.save
, it will call the save method, and self.save
will take as value what the object returned, but that is None
, hence the error.
You thus should remove the @property
decorator:
QUESTION
At the outset, let me just add that I am using Anylogic for the first time, please be understanding.
I have strange problem with conversion GIS .shp file to road network.
I follow the directions in the documentation (I'm trying to do exactly the same as in the documentation example):
https://anylogic.help/markup/converting-roads.html
As you can see, Anylogic generated a lot of road networks for me. It should all be in one road network. For this reason, there are no intersections and this is the biggest problem. It does not generate intersections at all, but joints these roads somehow artificially ...
Can anyone tell me what I am doing wrong? Why no intersections are generated and everything is thrown into separate road networks? In the example from the documentation, the intersections have been generated.
I am using Anylogic Professional 30 days trial. Previously I was using the Personal Learning Edition version and there was exactly the same problem.
...ANSWER
Answered 2021-May-29 at 06:52You are not doing anything wrong. It is caused by the shape file structure. AnyLogic can only interpret what it gets and if the data is not formatted correctly, i.e. road paths are not actually connected in the .shp file, it will create separate networks.
So either adjust the shape file or manually combine the networks, there is no other way, afaik.

QUESTION
I've seen some threads on how to remove the leaflet attribution in the bottom right. It seems like the creators of leaflet have no issue with it, so to save space I'd like to remove mine. Here is a thread on it, but no answers relate to Vue unfortunately. https://gis.stackexchange.com/questions/192088/how-to-remove-attribution-in-leaflet
I'm using nuxt but would greatly appreciate help if it's directed toward Vue. The l-tile-layer has an attribute-prop which indeed helps me add attributions, but removing it made me realize the attribution seem to be connected to the l-map component as it's visible with no tile layer.
TLDR: I want to remove the "Leaflet"
Suggestions?
...ANSWER
Answered 2021-May-19 at 20:52With the Leaflet API, it is removed by this config.
