django出现__init__() got an unexpected keyword argument 'mimetype‘ 问题解决

这种问题好多新手按照djangobook学习的时候应该都遇到过，是因为这是老的django的写法，新的django已经升级改变了很多东西。

处理方法如下：

I think you are not using the latest version of django-ajax-selects package.

There was a related fix made in July 2014:

• Django's HttpResponse object has deprecated the mimetype kwarg in 1.7

Either run pip with an upgrade flag:

pip install --upgrade django-ajax-selects

or, install it directly from github:

git clone https://github.com/crucialfelix/django-ajax-selects.git
cd django-ajax-selects
python setup.py install

According to a changeset, mimetype was replaced by content_type.

就是先升级django-ajax-selects，然后把代码里边的mimetype换成content_type，就OK了。
