problem with Django model

Question

Hi :) , I use Djnago a few weeks ago I started a django app and wrote these lines in model.py

    from django.db import models
class Publisher(models.Model):
    name = models.CharField(max_length=30)
    address = models.CharField(max_lenght=50)
    city = models.CharField(max_length=60)
    state_province = models.CharField(max_length=30)
    country = models.model.CharField(max_length=50)
    website = models.URLField()

class Author(models.Model):
    first_name = models.CharFiled(max_length=30)
    last_name = models.CharField(max_length=40)
    email = models.EmailField()

class Book(models.Model):
    title = models.CharField(max_length=100)
    authors = models.ManyToManyField(Author)
    publisher = models.ForeignKey(Publisher)
    publication_date = models.DateField()

When I trying to Validate or sqlall

python manage.py validate
or 
python manage.py sqlall appname

It print this error message

            Traceback (most recent call last):

    TypeError: __init__() got an unexpected keyword argument 'max_lenght'

Please help me to fix this error

Answer 1

The exception message couldn't be clearer:

TypeError: __init__() got an unexpected keyword argument 'max_lenght'

Here's the offending line, looks like a typo.

address = models.CharField(max_lenght=50)
                                   ^

Answer 2

don't want to be rude, but did you bother to read the error message?

unexpected keyword argument 'max_lenght'

(you've misspelled max_length)

Edit:

The sheer amount of error messages may be intimidating but there's a nice hint in the first line:

Traceback (most recent call last):

Start looking from the bottom, where indeed your error may be found.

Another tip (though no help this time) is to scan the code for errors in files you've written (as opposed to django library code), which is sometimes in the middle of the list.
