Kann nicht verstehen, warum ich einen Keyerror in meiner Django Python App bekomme

Question

Ich weiß, dass ein Schlüssel Fehler ausgelöst wird, wenn ein dict() Objekt angefordert wird (im Format a = adict [key]) und der Schlüssel nicht in der Wörterbuch. Aber mein Schlüssel ist da. Es ist mir zu sagen, dass die ‚einbetten‘ Schlüssel das Problem meines Code

, bevor ich die Einbettungs Schlüssel alles funktionierte gut aufgenommen. Wenn jemand meinen Fehler entdecken kann, lass mich bitte wissen, wo ich falsch gelaufen bin. Vielen Dank.

Der Schlüssel ist eindeutig nicht da, sonst würdest du keinen KeyError bekommen.

Sie legen den Schlüssel nicht in Ihrer scrape_and_store_vlad Methode fest.

def scrape_and_store_vlad(): 
    ... 
    entries = [{'href': url_two + div.a.get('href'), 
       'src': url_two + div.a.img.get('data-original'), 
       'text': div.find('p', 'entry-title').text, 
       'comments': make_soup(url_two + div.a.get('href')).replace("\\", ""), 
       'name': name, 
       'url': url_two + div.a.get('href') 
       } for div in titles][:6]
