Question

我正在尝试显示我的基本模板中的值，以便在单击标记时显示在子模板（placenamelist.html）中，但是无法识别这些值，它只是按原样打印。我已经将我的基本模板扩展到了孩子，但它仍然无效。我从python循环通过oracle使用jinja2渲染父模板，但子模板不呈现for循环值

Jinja模板

def getMarkers():
conn = cx_Oracle.connect(dsn="sgen", user="s14346", password=pw)
c = conn.cursor()
c.execute("SELECT A.PLACENAME_ID, A.OLD_NAME,  DBMS_LOB.substr(A.SUPPLEMENTARY,3000), B.ICON_PATH \n, A.DESCRIPTION, A.LATITUDE, A.LONGITUDE FROM PLACENAMES A, ICONS B WHERE A.ICON_ID = B.ICON_ID ORDER BY PLACENAME_ID")
markers = []
for row in c:
    markers.append([row[0],row[1],row[2],row[3],row[4], row[5], row[6]])
conn.close
return markers


def render_site(base_template):
env = Environment(loader=FileSystemLoader('../jinja'))
template = env.get_template('placenamelist.html')
return template.render(base_template='test_template.html', markers=markers)

markers = getMarkers()


print(render_site('test_template.html'))

Base_template

  {% for item in markers %}
 var marker{{ item[0] }} = L.marker({{ item[5:] }});

  // Create an element to hold all your text and markup
 var popup{{ item[0] }} = $('<div/>');

  // Delegate all event handling for the container itself and its contents to the container
   popup{{item[0]}}.on('click', '.special', function (){
  var url = "http://www.geos.ed.ac.uk/~s1774346/jinja/placenamelist.html#"+{{item[0]}};
  open(url);
        event.preventDefault();
}); 

  // Insert whatever you want into the container, using whichever approach you prefer
  popup{{item[0]}}.html(("<table height='90'><tr><td>{{ item[1] }}</td></tr><tr><td align='center'><b><i>{{ item[4] }}</b></i></td></tr><tr><td align='center'><button   class='special'><img src='../icon/contract.svg' height=30 width=30 /></button></td></tr></table>"));

  // Insert the container into the popup
  marker{{ item[0] }}.bindPopup(popup{{ item[0] }}[0]);
 markers.addLayer(marker{{ item[0] }});
 map.addLayer(markers)

  {% endfor %}

儿童模板（placenamelist.html）

Content-Type: text/html
 {% extends base_template %}

<!DOCTYPE html>

 <html lang="en">  
 <head>
    <link rel="stylesheet" type="text/css" href="https://www.geos.ed.ac.uk/~s14346/stylesheet.css"> 
  </head>
  <body>
<table> 
   {% for item in markers %}
<tr><td>{{ item[2] }} </td></tr> 
 {% endfor %}
</table>

</body>

无法在Jinja2中将父模板中的python值渲染为子模板
