This bug is driving me nuts. I am trying to create the backend of a website in python using flask. I am getting the following error and traceback:
KeyError
KeyError: 'person_id'

I have the following in a flask view function (_I'm using python 3.6):
#login_required
#main.route('/dashboard', methods=['GET', 'POST'])
def dashboard():
if request.method =='POST':
dash_data = namedtuple('dash_data',[('posting', str), ('folder', str)])
print(request.form.get('posting'))
posted_data= dash_data(posting=request.form.get('posting'),folder=request.form.get('folder'))
I'm getting:

'identifiers: %r' % name)
ValueError: Type names and field names must be valid identifiers: "('posting', <class 'str'>)"
What am I doing wrong?
namedtuple objects don't accept a list of (attribute, type) tuples, they just expect an iterable of attributes (or a single string):
namedtuple('dash_data', ('posting', 'folder'))
Or:
namedtuple('dash_data', 'posting folder')
Refer to the documentation for how to use namedtuple.
maybe you can use NamedTuple from typing module
using like follow:
from typing import NamedTuple
dash_data = NamedTuple('dash_data',[('posting', str), ('folder', str)])
Hi want to save the information being posted to the database. I am using python flask and this is the way i attempted it.
#app.route('/add-new-song',methods=['GET','POST'])
def add_new_song():
form = NewSongForm(request.form)
if form.validate_on_submit():
new_song = SongBook()
form.populate_obj(new_song)
db.session.add(new_song)
db.session.commit()
return render_template('add-new-song.html',form=form)
When i try this i get this error:
TypeError: __ init __() takes exactly 6 arguments (1 given)
Any thoughts on how to do this?
here are the models
class SongBook(db.Model):
id = db.Column(db.Integer, primary_key=True)
song_book = db.Column(db.String(80))
title = db.Column(db.String(120))
artist = db.Column(db.String(120))
disc_number = db.Column(db.String(120))
track_number = db.Column(db.String(120))

self.song_book = song_book
self.title = title
self.artist = artist
self.disc_number = disc_number
self.track_number = track_number
trace back

This is independent of the actual amount of arguments passed to the entity creator.

This is the db module:
class ndbc(ndb.Model):
val = ndb.PickleProperty(compressed=True, indexed=False)
key_name = ndb.PickleProperty(indexed=True)
#classmethod
def set(cls, key_t, val_t):

entity.put()

def save(obj, name):
return ndbc.set(name, obj)
Don't you mean entity = cls(val=val_t, key_name=key_t)? Also, key_name is an old db property. For ndb, you should use id:
https://docs.google.com/document/d/1AefylbadN456_Z7BZOpZEXDq8cR8LYu7QgI7bt5V0Iw/mobilebasic
Not sure id can be a PickleProperty. Interested to see if this works.
