_init__() got an unexpected keyword argument 'mimetype' in EXPORT

Question

I get this error when I try to export data from model through the xadmin pages.

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')

Environment:

I have added the list_export as suggested in the xadmin documents. But not much help. what am I doing wrong? Any suggestion would be much appreaciated. Thanks.

Answer 1

The version of xadmin that you have installed is not compatible with Django 1.7+ It is using the the mimetype argument, which was removed in Django 1.7.

The issue has been fixed in the master branch, but it doesn't look as if there has been a new release since then.

You could try installing the master branch, but I would be wary of using an app that hasn't had a release for so long, unless you're confident debugging issues like this.
