我正在使用Django 1.7.4和django_ajax_selects进行自动完成。
查找失败，我收到此错误：
__ init __（）得到了一个意外的关键字参数'mimetype'
完整的堆栈跟踪如下。我该怎么做才能解决这个错误？
是否可以调用GET而不是POST。 django_ajax_select是否进行了GET而不是POST？

You're seeing this error because you have DEBUG = True in your
Django settings file. Change that to False, and Django will
display a standard 500 page.

我认为您没有使用最新版本的django-ajax-selects软件包。
2014年7月进行了相关修复：
根据changeset，mimetype替换为content_type。
使用升级标志运行pip：
pip install --upgrade django-ajax-selects
或者直接从github安装：
git clone https://github.com/crucialfelix/django-ajax-selects.git
cd django-ajax-selects
python setup.py install
答案 1 :(得分：8)
在Django 1.6中，HttpResponse就像
if mimetype:
warnings.warn("Using mimetype keyword argument is deprecated, use"
" content_type instead",
DeprecationWarning, stacklevel=2)
content_type = mimetype
我们只是警告并将mimetype分配给content_type。
在Django 1.8中，我们没有使用mimetype。而不是直接这样，我们将类似＆＃34; image / png＆＃34;等等的值分配给content_type。只是一个干燥的概念。
例如
my_file = open('newimage.jpg','rb').read()
return HttpResponse(my_file, content_type = "image/png")
