我想在我的项目中使用 django reversion 应用程序。我有点困惑。如何在模板中显示更改列表 (field_dict.items())?
模型.py :
@reversion.register()
class Function(models.Model):
***FIELDS***
views.py :
def function_revisions(request, function_code):
function = get_object_or_404(Function, pk=function_code)
versions = Version.objects.get_for_object(Function)
context = {
'function': function,
'versions': versions,
}
return render(request, 'project/function_revisions.html', context)
function_revisions.html :
{% for version in versions %}
<p>Version: {{ forloop.counter }}.</p>
<p>Revision by {{ version.revision.user }}.</p>
<p>Date of revision : {{ version.revision.date_created }}.</p>
{% for field_name, field_value in version.field_dict.items() %} <-- ???
<p>Field </p>{{ field_name }} had the value {{ field_value }}<p>
{% endfor %}
{% endfor %}
错误 :

最佳答案
您将错误的内容传递给 get_for_object
- 您需要传递实例 function
,而不是模型 Function
。
