Django管理界面中的只读模型? [英] Readonly models in Django admin interface?

问题描述

如何在管理界面中将模型设为完全只读?这是一种日志表，我使用管理功能进行搜索、排序、过滤等，但不需要修改日志.

How can I make a model completely read-only in the admin interface? It's for a kind of log table, where I'm using the admin features to search, sort, filter etc, but there is no need to modify the log.

如果这看起来像重复，这里是不是我想要做的:

In case this looks like a duplicate, here's not what I'm trying to do:

• 我不是在寻找只读的字段(即使将每个字段设为只读仍然可以让您创建新记录)
• 我不想创建一个只读用户:每个用户都应该是只读的.

• I'm not looking for readonly fields (even making every field readonly would still let you create new records)
• I'm not looking to create a readonly user: every user should be readonly.

参见 https://djangosnippets.org/snippets/10539/

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 = [f.name for f in self.model._meta.get_fields()]

    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">
    <header style="display:none"><h1>{% trans "submit options"|capfirst context "heading" %}</h1></header>
    <ul>
       <li><a href="../" class="grp-button grp-default">{% blocktrans %}Back to list{% endblocktrans %}</a></li>
    </ul>
  </footer>
{% endblock %}
