允许查看，但不能更改！-Django

Question

是否可以授予用户查看权限，但不能更改或删除。

目前，我所看到的唯一权限是“添加”，“更改”和“删除” …，但是其中没有“读取/查看”功能。

我确实需要这样做，因为有些用户只能查看管理面板，以查看已添加的内容。

Answer 1

在admin.py中

# Main reusable Admin class for only viewing
class ViewAdmin(admin.ModelAdmin):

    """
    Custom made change_form template just for viewing purposes
    You need to copy this from /django/contrib/admin/templates/admin/change_form.html
    And then put that in your template folder that is specified in the 
    settings.TEMPLATE_DIR
    """
    change_form_template = 'view_form.html'

    # Remove the delete Admin Action for this Model
    actions = None

    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):
        #Return nothing to make sure user can't update any data
        pass

# Example usage:
class SomeAdmin(ViewAdmin):
    # put your admin stuff here
    # or use pass
在change_form.html中替换为：

{{ adminform.form.non_field_errors }}

有了这个：

<table>
{% for field in adminform.form %}
    <tr>
      <td>{{ field.label_tag }}:</td><td>{{ field.value }}</td>
    </tr>
{% endfor %}
</table>

然后通过删除以下行来删除提交按钮：

{% submit_row %}
