Django管理界面中的只读模型?
如何在管理界面中将模型完全设为只读?它用于一种日志表,我在其中使用管理功能来搜索,排序,过滤等,但无需修改日志。
万一这看起来像是重复的,这不是我想要做的:
- 我不是在寻找只读字段(即使将每个字段都设为只读也可以让你创建新记录)
- 我不是要创建一个只读用户:每个用户都应该是只读的。

class ReadOnlyAdminMixin(object): """Disables all editing capabilities."""
change_form_template = "admin/view.html"
def __init__(self, *args, **kwargs):
super(ReadOnlyAdminMixin, self).__init__(*args, **kwargs)
self.readonly_fields = self.model._meta.get_all_field_names()
def get_actions(self, request):
actions = super(ReadOnlyAdminMixin, self).get_actions(request)
del_action = "delete_selected"
if del_action in actions:
del actions[del_action]
return actions
def has_add_permission(self, request):
return False
def has_delete_permission(self, request, obj=None):
return False
def save_model(self, request, obj, form, change):
pass
def delete_model(self, request, obj):
pass
def save_related(self, request, form, formsets, change):
pass
templates / admin / view.html
{% extends "admin/change_form.html" %}{% load i18n %}
{% block submit_buttons_bottom %}
<div class="submit-row">
<a href="../">{% blocktrans %}Back to list{% endblocktrans %}</a>
</div>
{% endblock %}
templates / admin / view.html(用于Grappelli)
{% extends "admin/change_form.html" %}{% load i18n %}
{% block submit_buttons_bottom %}
<footer class="grp-module grp-submit-row grp-fixed-footer">
