允许查看，但不能更改！- 姜戈

Permission to view, but not to change! - Django(允许查看，但不能更改！- 姜戈)

问题描述

是否可以授予用户查看权限，但不能更改或删除.

is it possible to give users the permission to view, but not to change or delete.

目前我看到的唯一权限是添加"、更改"和删除"......但那里没有读取/查看".

currently in the only permissions I see are "add", "change" and "delete"... but there is no "read/view" in there.

我真的需要这个，因为有些用户只能查看管理面板，才能查看添加的内容.

I really need this as some users will only be able to consult the admin panel, in order to see what has been added in.

推荐答案

更新:自 Django 2.1 现在是内置的.

Update: Since Django 2.1 this is now built-in.

在 admin.py 中

In admin.py

# 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:

In change_form.html replace this:

{{ adminform.form.non_field_errors }}

用这个:

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

然后通过删除这一行来移除提交按钮:

Then remove the submit button by deleting this row:

{% submit_row %}
