Chapter 6 introduced Djangos admin interface, and now its time to circle back and take a closer
look.
第六章介绍了 Django 的管理界面,现在是该回过头来仔细了解一下的时候了。

As weve said a few times before, Djangos admin interface is one of the frameworks killer
features, and most Django developers find it time-saving and useful. Because the admin interface
is so popular, its common for Django developers to want to customize or extend it.

The last few sections of Chapter 6 offer some simple ways to customize certain parts of the
admin interface. Before proceeding with this chapter, consider reviewing that material; it
covers how to customize the admin interfaces change lists and edit forms, as well as an easy way
to rebrand the admin interface to match your site.
第六章的最后几节介绍了定制部分管理界面的一些简单方法。进入本章之前,请先复习一下那部分资料;其中涵盖了如何定制管理接口的 change list 和 edit forms ,以及如何将管理界面冠以与站点一致的风格。

Chapter 6 also discusses when and why youd want to use the admin interface, and since that
material makes a good jumping-off point for the rest of this chapter, well reproduce it here:

Obviously, the admin interface is extremely useful for editing data (fancy that). If you have
any sort of data entry task, the admin interface simply cant be beat. We suspect that the vast
majority of readers of this book will have a whole host of data entry tasks.
显而易见,对数据编辑工作来说,该管理界面极为有用(想象一下)。如果用于完成某种数据的录入工作,该管理界面实在是无人能及。我们猜想本书绝大多数读者都有成堆数据录入任务。

Djangos admin interface especially shines when nontechnical users need to be able to enter data;
thats the purpose behind the feature, after all. At the newspaper where Django was first
developed, development of a typical online feature a special report on water quality in the
municipal supply, say goes something like this:
Django管理接口特别关注那些没有技术背景的用户来使用数据录入;这也是该功能的开发目的。在Django最初开发地报社,开发一个典型的在线市政供水质量报告系统,需求如下:

*   While the reporter enters data into Django, the programmer can focus on developing the

In other words, the raison dtre of Djangos admin interface is facilitating the simultaneous work
of content producers and programmers.
换句话说,Django 管理接口之所以存在的首要目的是为了方便内容编辑人员和程序员同时开展工作。

However, beyond the obvious data entry tasks, we find the admin interface useful in a few other
cases:
当然,除了显而易见的数据录入任务之外,我们发现管理界面在其他一些情况下有是很有用处的。

*   *Inspecting data models* : The first thing we do when weve defined a new model is to call it
    up in the admin interface and enter some dummy data. This is usually when we find any data
    modeling mistakes; having a graphical interface to a model quickly reveals problems.

*   *Managing acquired data* : Theres little actual data entry associated with a site like
    ``http://chicagocrime.org`` , since most of the data comes from an automated source.
    However, when problems with the automatically acquired data crop up, its useful to be able
    to go in and edit that data easily.
*  *管理获得的数据* :很少有真实数据输入会和像 ``http://chicagocrime.org`` 这样的站点相关联,因为多数数据来自自动生成的源头。然而,当所获取的数据出错而导致麻烦时,能够便捷地找到并修改出错数据将会有助于问题解决。

Djangos admin interface handles these common cases with little or no customization. As with most
design tradeoffs, though, handling these common cases so well means that Djangos admin interface
doesnt handle some other modes of editing as well.
无需或者仅需略为定制之后, Django 管理界面就能处理绝大部分常见情形。然而,正是因为在设计上极力折衷, Django 管理界面能够很好地处理这种常见情形也就意味着它无法同样处理其它一些编辑模型。

Yes, its extremely simple but that simplicity is based on a whole host of assumptions. The
entire philosophy of Djangos admin interface follows directly from these assumptions, so lets
dig into the subtext of this phrase in the sections that follow.
是的,这非常的简单,但这种简单是建立在一整堆假定之上的。Django 管理界面的全部设计理念均直接遵循这些假定,因此让我们深入理解一下这些后续小节中所出现术语的含义。

The admin interface is designed to be used by people whom you, the developer, *trust* . This
doesnt just mean people who have been authenticated; it means that Django assumes that your
content editors can be trusted to do the right thing.
管理界面被设计成由你这样的开发人员所 *信任* 的人使用。这里所指的并非只是通过身份验证的人;而是说 Django 假定可以相信内容编辑者只会做对的事情。

22#翻译
This in turn means that theres no approval process for editing content if you trust your users,
nobody needs to approve of their edits. Another implication is that the permission system, while
powerful, has no support for limiting access on a per-object basis as of this writing. If you
trust someone to edit his or her own stories, you trust that user not to edit anyone elses
stories without permission.
反过来说,这也就意味着如果你信任用户,他们无需征得许可就能编辑内容,也没有人需要对他们的编辑行为进行许可。另一层含义是,尽管认证系统功能强大,但到本书写作时为止,它并不支持对象级基础的访问限制。如果你允许某人对自己的新闻报道进行编辑,你必须能够确信该用户不会未经许可对其他人的报道进行编辑。

The primary purpose of Djangos admin interface is to let people edit data. This seems obvious at
first, but again it has some subtle and powerful repercussions.
Django 管理界面的首要目的是让用户编辑数据。乍一看这是显而易见的,但仔细一想却又变得有点难以捉摸和不同凡响。
3318天前 翻译
25#翻译
For instance, although the admin interface is quite useful for reviewing data (as just
described), its not designed with that purpose in mind. For example, note the lack of a can view
permission (see Chapter 12). Django assumes that if people are allowed to view content in the
admin interface, theyre also allowed to edit it.
举例来说,虽然管理界面非常便于查验数据(如刚才所讨论的那样),但这并不是它的设计初衷。比如我们在第 12 章中谈到的,它缺少视图许可。Django 假定如果某人在管理界面中可以查看内容,那么也可以进行编辑。
3318天前 翻译
26#翻译
Another more important thing to note is the lack of anything even remotely approaching workflow.
If a given task requires a series of steps, theres no support for enforcing that those steps be
done in any particular order. Djangos admin interface focuses on *editing* , not on activities
surrounding editing. This avoidance of workflow also stems from the principle of trust: the
admin interfaces philosophy is that workflow is a personnel issue, not something to be
implemented in code.
还有件更重要的事情要注意,那就是对于远程调用工作流的缺乏。如果某个特定任务由一系列步骤组成,没有任何机制确保这些步骤能够以某个特定顺序完成。 Django 管理界面专注于 *编辑* ,而不关心修改周边的活动。对工作流的这种回避也源自于信任原则:管理界面的设计理念是工作流乃人为事物,无需在代码中实现。
3318天前 翻译
27#翻译
Finally, note the lack of aggregation in the admin interface. That is, theres no support for
displaying totals, averages, and so forth. Again, the admin interface is for editing its
expected that youll write custom views for all the rest.
最后,要注意的是管理界面中缺少聚合。也就是说,不支持显示总计、平均值之类的东西。再次重申,管理界面只用于编辑——它预期你将通过定义视图来完成其它所有工作。

As with the rest of Django, the admin interface wants you to work with structured data. Thus, it
only supports editing data stored in Django models; for anything else, such as data stored on a
filesystem, youll need custom views.

It should be clear by now that Djangos admin interface does *not* try to be all things to all
people; instead, we choose to focus tightly on one thing and do that thing extremely well.
现在可以肯定的是,Django 的管理界面 *并不* 打算成为所有人的万能工具;相反我们选择了专心做一件事情,并把它完成得尽善尽美。
3318天前 翻译
32#翻译
When it comes to extending Djangos admin interface, much of that same philosophy holds (note
that extensibility shows up nowhere in our goals). Because custom Django views can do *anything*
, and because they can easily be visually integrated into the admin interface (as described in
the next section), the built-in opportunities for customizing the admin interface are somewhat
limited by design.

You should keep in mind that the admin interface is just an app, albeit a very complicated one.
It doesnt do anything that any Django developer with sufficient time couldnt reproduce. Its
entirely possible that in the future someone will develop a different admin interface that is
based on a different set of assumptions and thus will behave differently.
必须记住,尽管管理界面很复杂,但它始终只是一个应用程序。只要有充足的时间,任何Django的开发者都能做到admin接口做到的所有事。
因此,我们需要寄希望于将来会有一个完全不同的admin接口会出现,这个新的接口拥有一系列不同的前提假设,并且工作方式也完全不同。

34#翻译
Finally, we should point out that, as of this writing, Django developers were working on a new
version of the admin interface that allows for much more flexibility in customization. By the
time you read this, those new features may have made their way into the bona fide Django
distribution. To find out, ask somebody in the Django community whether the newforms-admin
branch has been integrated.
最后要指出的是,在本文写作之时,Django 开发者们正在进行一个新的管理界面的开发工作,该版本将提供更多定制灵活性。当你阅读本文时,这些新特性也许已经进入了真实的 Django 发布之中。你可以向 Django 社区的某些人了解是否已经整合了 newforms-admin 主干代码。

For now, though, lets look at some quick ways of customizing the appearance (and, to some
extent, behavior) of the admin interface. Chapter 6 covers a few of the most common tasks:
rebranding the Django admin interface (for those pointy-haired bosses who hate blue) and
providing a custom admin form.

Past that point, the goal usually involves changing some of the templates for a particular item.
Each of the admin views the change lists, edit forms, delete confirmation pages, and history
views has an associated template that can be overridden in a number of ways.
更进一步的目标常常会包含,改变模板中的一些特殊的项。每一种admin的视图,包括修改列表、编辑表单、删除确认页以及历史视图,都有一个与之相关联的模板可以以多种方式来进行覆盖。

First, you can override the template globally. The admin view looks for templates using the
standard template-loading mechanism, so if you create templates in one of your template
directories, Django will load those instead of the default admin templates bundled with Django.
These global templates are outlined in Table 17-1.
首先,你可以在全局上覆盖模板。admin视图使用标准的模板载入机制来查找模板。所以如果你在模板目录中创建了一个新的模板,Django会自动地加载它。全局的模板在表17-1中列出。

Most of the time, however, youll want to change the template for just a single object or
application (not globally). Thus, each admin view looks for model- and application-specific
templates first. Those views look for templates in this order:

Why put the custom view *before* the admin inclusion? Recall that Django processes URL patterns
in order. The admin inclusion matches nearly anything that falls under the inclusion point, so
if we reverse the order of those lines, Django will find a built-in admin view for that pattern,
which wont work. In this particular case, it will try to load a change list for a ``Report``
model in the ``books`` application, which doesnt exist.
为什么要将定制试图置于管理内容 *之前* 呢?回想一下,Django 是按照顺序处理 URL 匹配式的。管理内容几乎匹配内容点之后所有的东西,因此如果我们把这几行的顺序颠倒一下, Django 将会为该匹配式找到一个内建管理视图,并将试图在 ``books`` 应用程序中为 ``Report`` 模型再入更新列表,而这却是不存在的。

    We use ``RequestContext`` as the third parameter (``context_instance`` ) to
    ``render_to_response`` . This ensures that information about the current user is available
    to the template.
我们将 ``RequestContext`` 用作 ``render_to_response`` 的第三个参数(``context_instance`` )。这就确保了模板可访问当前用户的信息。

Finally, well make a template for this view. Well extend the built-in admin templates to make
this view visually appear to be part of the admin interface:
最后, 我们为这个视图做一个模板。我们将扩展内置管理模板,

By extending ``admin/base_site.html`` , we get the look and feel of the Django admin for free.
Figure 17-2 shows what the end result looks like.
通过扩展 ``admin/base_site.html`` , 我们没费丝毫气力就得到了 Django 管理界面的外观。图 17-2 我展示了像这样的一个最终结果。

You can use this technique to add anything you can dream of to the admin interface. Remember
that these so-called custom admin views are really just normal Django views; you can use all the
techniques you learn in the rest of this book to provide as complex an admin interface as you
need.
使用该技术,你可以向管理界面中添加任何你梦想中的东西。需要记住的是这些被叫做定制管理视图实际不过是普通的 Django 视图,你可以使用在本书其它部分所学到的技术制作出符合自己需要的复杂管理界面。

At times the default admin views just dont cut it. You can easily swap in your own custom view
for any stage of the admin interface; just let your URL shadow the built-in admin one. That is,
if your view comes before the default admin view in the URLconf, your view will be called
instead of the default one.
有时缺省的管理视图无法完成某项工作。你可以轻松地换上自己的定制视图;只需要用自己的 URL 遮蔽内建的管理视图。也就是说,如果在 URLConf 中你的视图出现在缺省管理视图之前,你的视图将取代缺省视图被调用。

For example, we could replace the built-in create view for a book with a form that lets the user
simply enter an ISBN. We could then look up the books information from `http://isbn.nu/`_ and
create the object automatically.
举例来说,我们可以用一个让用户简单输入 ISBN 的窗体来取代内建的书籍创建视图。然后,我们可以从 `http://isbn.nu/`_ 查询该书的信息,并自动地创建对象。

If this bit comes before the admin URLs in your URLconf, the ``add_by_isbn`` view will
completely replace the standard admin view.
如果这个代码片段在 URLConf 中出现于管理 URL 之前, ``add_by_isbn`` 视图将完全取代标准的管理视图。

We could follow a similar tack to replace a delete confirmation page, the edit page, or any
other part of the admin interface.
按照这种方式,我们可以替换删除确认页、编辑页面或者管理界面的其它任何部分。

If youre a native English speakerand we expect that many readers of this English-language book
areyou might not have noticed one of the coolest features of the admin interface: its available
in almost 40 different languages! This is made possible by Djangos internationalization
framework (and the hard work of Djangos volunteer translators). The next chapter explains how to
use this framework to provide localized Django sites.
如果你的母语是英语——我们预料这本英文书的许多读者都是——你可能还没有注意到本书最酷的特性——它提供 40 种不同的语言!这大概益于 Django 的国际化架构(以及 Django 翻译志愿者的辛勤劳动)。下一章讲解如何使用该架构打造本地化 Django 站点。
