Migration error in django models.py database

Question

My app is installed correctly and its models.py reads:

from django.db import models

class Album(models.Model):
    artist = models.CharField(max_lenght=250)
    album_title = models.CharField(max_lenght=500)
    genre = models.CharField(max_lenght=100)
    album_logo = models.CharField(max_lenght=1000)

class Song(models.Model):
    album = models.ForeignKey(Album, on_delete=models.CASCADE)
    file_type = models.CharField(max_lenght=10)
    song_title = models.CharField(max_lenght=250)

But whenever I run python manage.py migrate, I get the following error:

Traceback (most recent call last):
  File "manage.py", line 15, in <module>

    super().__init__(*args, **kwargs)
TypeError: __init__() got an unexpected keyword argument 'max_lenght'

What could be wrong? I'm still a beginner and I'm still learning about databases.

OMG! That's why copying and pasting code can be dangerous sometimes. Thank you! — Douglas Gondim

Use this:

As per my comment, length (lenght) splelling is wrong.

from django.db import models


class Album(models.Model):
    artist = models.CharField(max_length=250)
    album_title = models.CharField(max_length=500)
    genre = models.CharField(max_length=100)
    album_logo = models.TextField()

class Song(models.Model):
    album = models.ForeignKey(Album, on_delete=models.CASCADE)
    file_type = models.CharField(max_length=10)
    song_title = models.CharField(max_length=250)

You have spelled length wrong here

album_title = models.CharField(max_lenght=500)

happens to the best of us.
