Include Shapeeditor urls in urls.py, then we can open the editor from the site, draw the shape and download as a shapes.txt or import it to the database.

urlpatterns = [
    path('shapeeditor/', include('shapeeditor.urls')),
]

Just to be sure database is ok run the next commands.

./manage.py makemigrations
./manage.py migrate

Usage

./manage.py runserver localhost:8080

## Open the editor in your favorite browser
firefox localhost:8080/shapeeditor

Map interface allows the user to draw a shape, cut links and delete links and nodes, to create a shape you need to define two endpoints then put waypoints between the begin and end, more waypoints means better aproximation.

Most of the features are already implemented in JS but there is not a GUI equivalent to call for methods yet.

Shapes are made with nodes, nodes have a type, it could be endpoint for start or end of shapes, stops, these can be part of the shape too, fork are the nodes where are more than two links, waypoint are the common nodes. To create a Shape first draw paths clicking on map with the interaction add_node, when you already have a connection between two endpoints through multiple nodes and links add a Shape in the section below, once added the shape pick the waypoints with select_node + Shift, when you pick a waypoint and it is in a shape segment, the whole segment is selected, pick only waypoints their segments are in the shape.

Pick waypoints from the start node to the final node, keep the waypoints in order to avoid backward motion, when you pick a waypoint the section>accordion for the shape we are adding the waypoints will show the waypoints list, when the the waypoints are enough click on save button to write the shape, then push it to database.
