Controller Problem(Dispalying points to the map)

[martjan dedi]

HI Guys 

I am having trouble to display the points of the example given in the tethys website.

I run the code below and no errors but the points don't display to the map.(The code is from controllers.py file)

If someone can take a look at my question and help me ill be very graceful.

Thanks and Happy Coding.

The code is shown below :

import json

from django.shortcuts import render

from django.contrib.auth.decorators import login_required

from tethys_apps.sdk.gizmos import *

from .model import SpatialSessionMaker , SpatialAddressPoint

from tethys_gizmos.gizmo_options import MapView, MVLayer, MVView

import geoalchemy2

@login_required()

def home(request):

session = SpatialSessionMaker()

address_points = session.query(SpatialAddressPoint.geom.ST_AsGeoJSON()).all()

features = []

for address_point in address_points:

address_point_feature = {

'type':'Feature',

'geometry': json.loads(address_point[0])

}

features.append(address_point_feature)

geojson_address_points = {

'type' : 'FeatureCollection',

'crs':{

'type':'name',

'properties':{

'name': 'EPSG:4326'

}

} ,

'features':features

}

address_points = MVLayer(

source = 'GeoJSON',

options = geojson_address_points,

legend_title = 'jani',

)

initial_view = MVView(

                projection='EPSG:4326',

                center=[-100, 40],

                zoom=2,

                maxZoom=20,

                minZoom=2

            )

map_options = MapView(height = '600px',

              width= '100%',

              layers= [address_points],

              legend=True,

              basemap= 'OpenStreetMap',

              view=initial_view

    

        )

context = {'map_options': map_options}

session.close()

return render(request, 'postgis_app/home.html', context)

Do you get any JavaScript errors? If you are using Chrome, right-click anywhere on the page and select inspect element. Then take a look at the Console tab. Post any errors you received.
