Incorrect default value for verify_exists in URLField documentation

[Mark Tran]

The Django documentation states that the default value for the keyword argument "verify_exists" is True:

​http://docs.djangoproject.com/en/dev/ref/models/fields/#urlfield

​http://code.djangoproject.com/browser/django/trunk/docs/ref/models/fields.txt#L799

I've noticed that the default value is actually False:

​http://code.djangoproject.com/browser/django/trunk/django/forms/fields.py#L532

In [1]: from django import forms
In [2]: url = forms.URLField()
In [3]: url.validators[0].verify_exists
Out[3]: False

Default values are set according to the document and some changes are made to other code to pass pylint check

[Russell Keith-Magee]

When the implemenation has existed as-is for as long as it has, we fix the documentation, not the code. Changing the code would be backwards incompatible for anyone using (and relying on) the existing implementation.

Actually this is documented correctly. The default for form fields is False, but the default for model fields is True.

>>> from django.db import models
>>> models.URLField().validators
[<django.core.validators.MaxLengthValidator object at 0x27d34d0>, <django.core.validators.URLValidator object at 0x27d3510>]
<django.core.validators.URLValidator object at 0x27d3490>
>>> models.URLField().validators[1].verify_exists
True
