自定义file_view以在浏览器中查看pdf [英] Customise file_view to view pdfs in the browser
问题描述
我仍在为内部网运行Plone 3.0.6.我曾尝试升级到当前版本，但始终遇到障碍.当我有更多时间时，我会再去那儿.
I am still running Plone 3.0.6 for our Intranet. I have tried to upgrade to current version, but always come up against a road block. I'll have another go at that later when I have more time.
现在，我只需要自定义/portal_skins/plone_content/file_view即可在浏览器中打开pdf附件，而无需下载它们.我们正在安装一个新的信息亭系统，该信息亭系统将在浏览器中显示PDF，但无法浏览和查看文件系统中的文件.
For now, I just need to customise /portal_skins/plone_content/file_view to make it open pdf attachments in the browser instead of downloading them. We are installing a new kiosk system that will display PDFs in the browser but can't browse and view files in the filesystem.
我已经进行了很多搜索，发现其他人已经这样做了，但是还没有找到我正在运行的版本.我不是任何类型的开发人员，所以我不知道如何做他们在系统上所做的事情.
I've done a lot of searching and found others who have done this, but not for the version I'm running. I'm not a developer of any sort, so I can't figure out how to do what they have done on my system.
这是file_view的当前代码.
Here is the current code for file_view.

</div>
<div tal:replace="structure provider:plone.belowcontentbody" />
</tal:main-macro>
</div>
</body>
</html>
我也搜索了at_download，并找到了/Plone/portal_skins/archetypes/at_download.它包含以下代码:
I've also done a search for at_download and found /Plone/portal_skins/archetypes/at_download. It contains this code:
if traverse_subpath:
field = context.getWrappedField(traverse_subpath[0])
else:
field = context.getPrimaryField()
return field.download(context)
任何人都可以告诉我要在浏览器中查看PDF时需要更改的内容吗?
Can anyone tell what I need to change to make PDFs view in the browser?
当前，当我选择一个PDF链接时，它看起来像这样. http://intranet.internal.lan/somewhere/Test.pdf/at_download/file
Currently when I select a link to a PDF it looks like this. http://intranet.internal.lan/somewhere/Test.pdf/at_download/file
我需要它看起来像这样.
I need it to look like this.
http://intranet.internal.lan/somewhere/Test.pdf
(没有/at_download/file)
(without /at_download/file)
任何帮助将不胜感激.
谢谢

推荐答案
我不知道它是否适用于plone 3.x.x，但是 我使用的是plone 4.1.6，我想渲染一个pdf文件 在浏览器中(在chrome和firefox中工作)并像这样放置 在页面模板中:
I don't know if it's work in plone 3.x.x, but I am using plone 4.1.6 and I wanted to render a pdf file in a browser (worked in chrome and firefox) and put like this in a page tamplate:
<a tal:attributes="href string:${edicao_url}/@@images/field_pdf" target="_blank">View PDF</a>
其中的网址显示:
http://localhost:8080/plone_site/content-type/@ @ images/field_pdf/
因此，字段field_pdf是内容类型的属性！ 啊，我也使用了敏捷的内容类型！
So, the field field_pdf is an attribute from a content-type! Ah, and I am using too a content type from Dexterity!
