I have 2 question cause little bit comfused with django-reversion app. I have page where users can see list all of reversions. Every version has button to revert.
1 Question: How to show only some fields of changes. Right now it shows me all fields. I use version.field_dict.items.
2 Question: How to make correct revert to specific version?
Here below you can see code but it raise Error in views.py when I try to click to revert link. What I did wrong?
template.html
{% for version in versions %}
{% for field_name, field_value in version.field_dict.items %}
{{ field_name }}
{{ field_value }}
{% endfor %}
<a href="{% url 'project:group_task_revert' project_code=project.code group_task_code=group_task.code group_task_reversion_id=version.revision.id%}">REVERT</a>
{% endfor %}
urls.py:
url(r'^(?P<project_code>[0-9a-f-]+)/(?P<group_code>[0-9a-f-]+)/(?P<group_reversion_id>\d+)/$',
group_revert,
name='group_revert'),
views.py:
def group_revert(request, project_code, group_code, group_reversion_id):
project = get_object_or_404(Project, pk=project_code, status='open')
group = get_object_or_404(Group, pk=group_code)
versions = Version.objects.get_for_object(group)
versions[group_reversion_id].revision.revert()
return redirect('project:project_detail', project_code=project.code)
