RE: [Zope] Best Practice for including Javascript in Zope Applications
Hello, Ok, I came up with a solution that I like; today I spent a little while making it so I don't have to load things into memory before they are served. Now it works quite nicely for serving out js/css/gui pics. I won't post what I did right now, as I haven't really cleaned it up and I'm ashamed of how it looks at the moment, but I'll post the usage of it to see if anyone would like to use it after I clean it up: ... from util import FileSystemResource #it's just in a utility module for my current project at the moment ... MyZopeObject(Implicit,Item,Whatever): #js and css are paths that are considered relative to my package directory (not the cwd for zope). It can be absolute too, if desired. js = FileSystemResource(js,Javascript Repository) css = FileSystemResource(css,CSS Repository) Now, say that there is ext-all.js in a directory called /path/to/zope/Products/MyProduct/js/. You could then link to the java script file by going to http://domain.com:8080/myZopeObject/js/ext-all.js. In particular, in dtml, I have a standard_html_header that looks something like this: ==standard_html_header.dtml== html head !--Set the title-- titledtml-var title/title dtml-commentscript src=dtml-absolute_url;/js/navbar.js/!--GUTS navbar--/dtml-comment link rel=stylesheet type=text/css href=dtml-absolute_url;/js/resources/css/ext-all.css !--Source in local_js unless the variable isn't defined-- dtml-try dtml-in expr=local_js script src=dtml-absolute_url;/js/dtml-sequence-item;/ /dtml-in dtml-except!--Do nothing-- /dtml-try /head !--Start the body-- body class=dtml-id;-body id=dtml-id;-body !--Set basic pre-nav header-- dtml-unless NO_HEADER h1 id=main-titleThis is a title./h1 /dtml-unless ==!End standard_html_header.dtml== Then in MyZopeObject, I wrap up my DTML in a method like so: ..other class stuff... _main = DTMLFile(dtml/main,globals()) def main(self): main_js=[ext-all.js,main.js] return _main(self.REQUEST,local_js = main_js) I did the whole local_js thing so I could control what JS got dropped into what pages without having to write a different header for each one. I will probably also do the same thing for the css just in case I want page-specific css files. This is what I'm doing at the moment, and it's working great. If this would be useful to someone else, I'll give it more than an hour and a half of thought, rewrite it more intelligently, and make it available. Otherwise, thanks to everyone for their comments! -Matt -Original Message- From: Tim Nash [mailto:[EMAIL PROTECTED] Sent: Thursday, January 03, 2008 12:38 PM To: Matt Hollingsworth Cc: zope@zope.org Subject: Re: [Zope] Best Practice for including Javascript in Zope Applications Matt, Please keep us updated on your strategy for serving extjs.

I realize that zope's principle is to store everything in the database, but this is unacceptable for content such as video files, right? I mean the ZODB file would be absolutely humongous (and slow? I don't know for sure how it's implemented). If there isn't already a working solution, I would be happy to come up with one; I could just hack out the parts of LocalFS that work, add a few features, and repackage it into a new product. It's not difficult to do (my little trivial solution already would work fine if I did a non-dumb implementation of the file-serving logic), and as much as I would like to use it for other projects, it would be worth my time. For example, I want to make a little video/music server as a personal project unrelated to my current one, and I really don't want to store things in the ZODB if I can help it... 1 video = +1 gig ZODB? :S I don't know much about zope obviously, so if I get some vehement objections to this route, I'll pick another :) Thanks! -Matt -Original Message- From: Tim Nash [mailto:[EMAIL PROTECTED] Sent: Wednesday, January 02, 2008 2:03 PM To: Tom Von Lahndorff Cc: Matt Hollingsworth; zope@zope.org Subject: Re: [Zope] Best Practice for including Javascript in Zope Applications I am writing an application that uses extjs as the front end and zope on the back and they work together really well.
