I read data from postgressql to get a latitude, longitude, and name of a JPEG file. I'm going through the record to create markers on a map. I do not receive an error message, but the card is not displayed.

I display data on the index.html page. I use iframe to display map.html. I have read a number of topics on this topic, but none of the answers work for me.

views.py:

from django.shortcuts import render
from django.http import HttpResponse
from .models Import PhotoInfo
Import folium

# Create your views here.
def index (request):
VarPhotoInfo = PhotoInfo.objects.order_by (& # 39; DateTaken & # 39;)

context = {& # 39; PhotoInfo & # 39 ;: VarPhotoInfo}

return render (request, & # 39; natureapp / index.html & # 39 ;, context)

def show_map (request):
PhotoInfo1 = PhotoInfo.objects.order_by (& # 39; DateTaken & # 39;)
m = folium. Map ([33.571345, -117.763265]zoom_start = 10)

test = folium.Html (& # 39;Hello World& # 39 ;, script = true)
popup = folium.Popup (test, max_width = 2650)
folium.RegularPolygonMarker (location =[33.571345, -117.763265], popup = popup) .add_to (m)
fg = folium.FeatureGroup (name = "MyMap")
for i in PhotoInfo1:
fg.add_child (folium.Marker (location = (float (i.Lat), float (i.Long)), popup = str (i.DateTaken) + & 39; file: & # 39; + i.PhotoName, icon = folium.Icon (color = # green #)))
m.add_child (fg)
m.get_root (). render ()

context = {& # 39; MyMap & # 39 ;: m}

return render (request, & # 39; natureapp / map.html & # 39 ;, context)

map.html:

  
    
    
      
Card goes here 
{{}} My_map.render

index.html:

  
    
    
      
Here it is! 
 {% if PhotoInfo%}
{% for photo in PhotoInfo%}
 
there is info.
   
    {{}} Photo.PhotoName
   
    {{}} Photo.Lat
   
    {{}} Photo.Long
   
  
  
  
  
  {% endfor%}
{% else%}
 
There is no information.
 {% endif%}
 

Index.html displays data correctly. Map.html shows only the heading "Map goes here". There is no error message.
