Question

当我尝试通过xadmin页面从模型导出数据时出现此错误。

Class ModelAdmin(object):
    reversion_enable = True
    list_display = (
    'name', 'description', 'pref_name', 'target_type', 'organism', 'tax_id', 'chembl_id', 'uniprot_accession')
    search_fields = ['name', 'description', 'chembl_id', 'uniprot_accession', 'pref_name']
    style_fields = {'description': "rich-textarea"}
    list_export = ('xls', 'xml', 'json', 'csv')

Exception Type: TypeError at /xadmin/idg/moleculedictionary/
Exception Value: __init__() got an unexpected keyword argument 'mimetype'

我已按照xadmin文档中的建议添加了list_export。但帮助不大。我究竟做错了什么？任何建议都会得到很大的启发。感谢。

Answer 1

您安装的xadmin版本与Django 1.7+不兼容它使用的mimetype参数为removed in Django 1.7。

问题一直是fixed in the master branch，但从那时起看起来并没有新版本。

你可以尝试安装master分支，但我会谨慎使用一个没有发布这么久的应用程序，除非你有信心调试这样的问题。

_init __（）得到了一个意想不到的关键字参数＆＃39; mimetype＆＃39;在出口
