博客升级，Django1.6 to Django1.7的坑

第一个坑，django-ckeditor引发，

File "manage.py", line 10, in 
    execute_from_command_line(sys.argv)
  File "/Library/Python/2.7/site-packages/Django-1.7-py2.7.egg/django/core/management/__init__.py", line 385, in execute_from_command_line
    utility.execute()
  File "/Library/Python/2.7/site-packages/Django-1.7-py2.7.egg/django/core/management/__init__.py", line 354, in execute
    django.setup()
  File "/Library/Python/2.7/site-packages/Django-1.7-py2.7.egg/django/__init__.py", line 21, in setup
    apps.populate(settings.INSTALLED_APPS)
  File "/Library/Python/2.7/site-packages/Django-1.7-py2.7.egg/django/apps/registry.py", line 115, in populate
    app_config.ready()
  File "/Library/Python/2.7/site-packages/Django-1.7-py2.7.egg/django/contrib/admin/apps.py", line 22, in ready
    self.module.autodiscover()
  File "/Library/Python/2.7/site-packages/Django-1.7-py2.7.egg/django/contrib/admin/__init__.py", line 23, in autodiscover
    autodiscover_modules('admin', register_to=site)
  File "/Library/Python/2.7/site-packages/Django-1.7-py2.7.egg/django/utils/module_loading.py", line 74, in autodiscover_modules
    import_module('%s.%s' % (app_config.name, module_to_search))
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/importlib/__init__.py", line 37, in import_module
    __import__(name)
  File "/Users/Alan/Workspace/laonan.net/member/admin.py", line 37, in 
    class UserChangeForm(forms.ModelForm):
  File "/Library/Python/2.7/site-packages/Django-1.7-py2.7.egg/django/forms/models.py", line 284, in __new__
    opts.help_texts, opts.error_messages)
  File "/Library/Python/2.7/site-packages/Django-1.7-py2.7.egg/django/forms/models.py", line 210, in fields_for_model
    formfield = f.formfield(**kwargs)
  File "/Library/Python/2.7/site-packages/django_ckeditor-4.2.8-py2.7.egg/ckeditor/fields.py", line 18, in formfield
    return super(RichTextField, self).formfield(**defaults)
  File "/Library/Python/2.7/site-packages/Django-1.7-py2.7.egg/django/db/models/fields/__init__.py", line 1892, in formfield
    return super(TextField, self).formfield(**defaults)
  File "/Library/Python/2.7/site-packages/Django-1.7-py2.7.egg/django/db/models/fields/__init__.py", line 842, in formfield
    return form_class(**defaults)
  File "/Library/Python/2.7/site-packages/django_ckeditor-4.2.8-py2.7.egg/ckeditor/fields.py", line 24, in __init__
    super(RichTextFormField, self).__init__(*args, **kwargs)
TypeError: Error when calling the metaclass bases
    __init__() got an unexpected keyword argument 'max_length'

填坑：把django-ckeditor升级到4.4+，并且重新执行python manager collectstatics更新静态资源，还有，需要在settings.py单独为ckeditor加上jquery引用。

CKEDITOR_JQUERY_URL = '//ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js'

第二个小坑，执行python manager.py runserver，结果如下:

Performing system checks...

System check identified some issues:

WARNINGS:
?: (1_6.W001) Some project unittests may not execute as expected.
	HINT: Django 1.6 introduced a new default test runner. It looks like this project was generated using Django 1.5 or earlier. You should ensure your tests are all running & behaving as expected. See https://docs.djangoproject.com/en/dev/releases/1.6/#new-test-runner for more information.

System check identified 1 issue (0 silenced).

You have unapplied migrations; your app may not work properly until they are applied.
Run 'python manage.py migrate' to apply them.

第二个issue很好办，执行一下python manage.py migrate就完了，至于前面blabla关于unittests的部分，偶卖糕的，还要写单元测试啊。

最后，如果懒的话，在settings.py里加上这么一句吧，这下世界清静了。

TEST_RUNNER = 'django.test.runner.DiscoverRunner'

最后，博客URL改为UUID，其实我是很喜欢数字作为url的一部分的，多简洁，可是，为了防垃圾爬虫，改先，万一以后我这博客是知名博客了，再来改就来不及了。
