Type Error:() hat ein unerwartetes Schlüsselwortargument erhalten

Question

Ich habe Probleme herauszufinden, wo meine Funktion editMenuItem() das unbekannte Schlüsselwortargument restaurant_id abbekommt. Ich habe ähnliche Fragen durchsucht und finde keine Lösung. Wenn jemand irgendwelche Vorschläge hat, würde ich sie sehr schätzen.

editMenuItem()

### Edit a menu item. ### 
@app.route('/restaurant/<int:restaurant_id>/menu/<int:menuitem_id>/edit/', 
      methods=['GET', 'POST']) 
def editMenuItem(menuitem_id): 
    menuitem = session.query(MenuItem).filter_by(id=menuitem_id).one() 
    if request.method == 'POST': 
     if request.form['newname']: 
      menuitem.name = request.form['newname'] 
     if request.form['newdescription']: 
      menuitem.description = request.form['newdescription'] 
     if request.form['newprice']: 
      menuitem.description = request.form['newprice'] 
     session.add(menuitem) 
     session.commit() 
     return redirect(url_for('showMenu', restaurant_id=menuitem.restaurant_id)) 
    else: 
     return render_template('editMenuItem.html', menuitem=menuitem) 

Relevant html

{% extends "base.html" %} 
{% block content %} 
<div class="row"> 
    <div class="six columns"> 
    <form action="{{ url_for('editMenuItem', menuitem_id = menuitem.id) }}" method="post">

Ich bin mir nicht sicher, wo dieses Schlüsselwort Argument herkommt, wie die restaurant_id sollte geben, um für meine Funktion nicht notwendig Arbeit. Was mache ich hier falsch? Vielen Dank.

Answer 1

Dank Wombatz Hinweis konnte ich das Problem lösen, indem ich meine editMenuItem Funktion änderte und die notwendige Vorlage änderte.

Aktualisiert Funktion:

### Edit a menu item. ### 
@app.route('/restaurant/<int:restaurant_id>/menu/<int:menuitem_id>/edit/', 
      methods=['GET', 'POST']) 
def editMenuItem(menuitem_id, restaurant_id): 
    menuitem = session.query(MenuItem).filter_by(id=menuitem_id).one() 
    restaurant = session.query(Restaurant).filter_by(id=restaurant_id).one() 
    if request.method == 'POST': 
     if request.form['newname']: 
      menuitem.name = request.form['newname'] 
     if request.form['newdescription']: 
      menuitem.description = request.form['newdescription'] 
     if request.form['newprice']: 
      menuitem.description = request.form['newprice'] 
     session.add(menuitem) 
     session.commit() 
     return redirect(url_for('showMenu', restaurant_id=menuitem.restaurant_id)) 
    else: 
     return render_template('editMenuItem.html', menuitem=menuitem, restaurant=restaurant) 

Aktualisiert Vorlage:

<form action="{{ url_for('editMenuItem', menuitem_id = menuitem.id, restaurant_id = restaurant.id) }}" method="post"> 

<a href="{{ url_for('showMenu', restaurant_id=menuitem.restaurant_id) }}" class="button">Cancel</a> 

Ich bin neu diese Seite zu verwenden, damit ich nicht sicher bin, ob ich Ihren Kommentar wombatz „upvote“, aber dank für den Hinweis.
