django-simple-history，TemplateDoesNotExist 位于 /admin/shared_models/mannedsetting/1/history/ simple_history/object_history.html

Question

我正在使用 django-history-admin

我有模特班

class MannedSetting(BaseModel):
    history = HistoricalRecords()
    class Meta:
        db_table = 't_manned_setting'
    confirm_msg = m.CharField(max_length=400)

然后在admin.py中

from simple_history.admin import SimpleHistoryAdmin
class MannedSettingAdmin(SimpleHistoryAdmin):
    list_display = ["id","confirm_msg"]
admin.site.register(MannedSetting,MannedSettingAdmin)

MannedSetting

实例编辑页面出现历史记录按钮

但是当点击按钮时，出现这个错误。

如果您在设置过程中忘记将

simple_history

添加到项目设置中的

INSTALLED_APPS

，则会出现此错误

INSTALLED_APPS = [
    # ...
    'simple_history',
]

您可以在项目上找到安装说明快速入门
