我尝试自定义管理菜单中显示的export_as_csv
操作,以便我可以向导出的CSV文件添加动态字段。这是通过使用提供django-adminactions操作的Export as CSV。到目前为止,我有以下内容:
from django.contrib import admin
from adminactions.api import csv_options_default, export_as_csv as _export_as_csv
from myapp.models import MyModel
class MyModelAdmin(admin.ModelAdmin):
list_display = ('field1', 'field2', 'field3')
qs = MyModel.objects.all()
options = csv_options_default
fields = ['field4', 'field5']
header = ['Header4', 'Header5']
actions = [_export_as_csv(queryset=qs, fields=fields, header=header, options=options)]
admin.site.register(MyModel, MyModelAdmin)
但是上面的内容会在页面上生成错误,如下所示:
hasattr(): attribute name must be string
Request Method: GET
Request URL: http://localhost:8000/admin/mymodel/mymodel/
Django Version: 1.4.14
Exception Type: TypeError
Exception Value:
hasattr(): attribute name must be string
Exception Location: /home/me/.virtualenvs/myproj/local/lib/python2.7/site-packages/django/contrib/admin/options.py in get_action, line 648
Python Executable: /home/me/.virtualenvs/myproj/bin/python
Python Version: 2.7.6
我是以正确的方式做到这一点的吗?如何在管理员中为Django的export_as_csv
函数添加动态字段?

我做了一会儿:
https://djangosnippets.org/snippets/2995/
可以像这样使用:
class ExampleModelAdmin(admin.ModelAdmin):
raw_id_fields = ('field1',)
list_display = ('field1', 'field2', 'field3',)
actions = [download_as_csv("Export Special Report"),] # custom label for action
download_as_csv_fields = [
'field1', # will use Django field verbose_name as col name
('foreign_key1__foreign_key2__name', 'label2'), # traverse relations with __ syntax
('field3', 'label3'), # custom col name
],
download_as_csv_header = True # output a header row in the csv

你必须以可调用的方式包含你的电话,但只在你的行动中声明你的名字:
from adminactions.api import export_as_csv as _export_as_csv
def my_export_as_csv(modeladmin, request, queryset):
return _export_as_csv(modeladmin.qs,
fields=modeladmin.fields,
header=modeladmin.header,
filename=None,
options=modeladmin.options,
out=None)
class MyModelAdmin(admin.ModelAdmin):
list_display = ('field1', 'field2', 'field3')
qs = MyModel.objects.all()
options = csv_options_default
fields = ['field4', 'field5']
header = ['Header4', 'Header5']
actions = [my_export_as_csv]
