Printing system in Zope
by Jason Spisak 24 Mar '00

24 Mar '00

Felipe, i had the ned for this too at the start of my current project. I actually have the fortune of having a smart printer. If I shoot a pdf via lpr, it just prints it. It's an HP 4050. lpr -P HP4050_raw myfile.pdf works fine. So I was just writing an external method to slap that document to my printer. But I stopped thinking about this because we decided online delivery of all documents was okay and other things took priority. If you wanted to print more than just plain text, I guess the mime type would have to have a "printer" application sort of, or filter just like they have "viewers". -- Jason Spisak 444(a)hiretechs.com

Clever about object updating
by Jason Spisak 24 Mar '00

24 Mar '00

Michel, > Do some benchmarks, ZODB is very fast if you are a little more clever > about how you change your objects. Is there a place where we developers can learn what "clever" means in this regard. I would love to know what i can do as a developer to gain speed when changing my objects. What are some of the secrets? All my best, -- Jason Spisak 444(a)hiretechs.com -- Jason Spisak 444(a)hiretechs.com

Newbie question: using backing files.
by Michael T. Richter 24 Mar '00

24 Mar '00

I have a situation where there are some HTML files which I do not control that I would like to open up to access through my Zope server. I don't want to import these HTML files as Zope objects because these files will frequently be edited and updated in place and I want any changes made to these HTML sources to be immediately reflected in Zope as they occur. I also don't want to just use a URL to access them because a) the end-users shouldn't be aware that they're exiting Zope scope for these items and b) no URL could possibly point to these files since they're actually stored in a revision control system through a "view" (in essence, a virtual local directory tree). So what this basically boils down to is this: I'd like to take a URL like this... http://my.intranet.site/Documentation/ComponentSpecs/MyComponent.html ...and have the logic behind it conform roughly to the following pseudocode: 1. Switch to "/viewdir/source/component/MyComponent/doc". 2. Open the file "ComponentSpec.html". 3. Serve up the contents of that file to the user. The user should see no visible signs that the data comes from outside of the Zope environment. I've already investigated using an external method to accomplish some of this. For example I served up an outside file in almost exactly the way I wanted to accomplish this using code like the following: def testMethod(): s = "" f = open("/viewdir/[...]/ComponentSpec.html", "r") for l in f.readlines(): s = s + l[:-1] return s Indeed this does EXACTLY what I want. (In any production version of this--this was only a quick'n'dirty hack--I'd be doing some significant caching and version checking. But the example gets the drift across.) The only problem is that I can't figure out how to translate a URL like the one I provided above into a method call like testMethod("MyComponent"). (The documentation on these things is a bit... spare.) So does anybody out there have any suggestions? I'm not afraid to get my hands dirty with Python (it being my scripting language of choice for the past 4+ years) and I'm not afraid to learn Stupid DTML Tricks. I just don't know enough Zope yet to even be dangerous.

PropertySheets again (QUEST)
by Oscar Picasso 24 Mar '00

24 Mar '00

Hi, As I didn't receive any answer from my previous message, I guess it wasn't very clear. How can I get a list of property.ids, property.types of a ZClass propertysheet from outside the product containing my ZClass. I tried a lot of things but i hit a wall. Thanks

I haven't bought the eMatter edition of Learning Python =), but I did by the Eff-bot's guide. I was able to print it fine, although personally I prefer nicely bound books to large amounts of single-sided A4/letter pages with too much whitespace around the borders. Also, know that some folks have had problems with eMatter's distribution schemes, especially those with non-US installations of Windows, from what I gather. Luckily, I hear that fatbrain's technical support helps folks get past these issues. On the positive side, I do like the ability to search PDF files. --David Ascher PS: Even more off-topic, and shameless promotion: Learning Python is now available in German (Einf\"uhrung in Python) and French (Introduction \'a Python). ObZope: Overheard at the SD2000 conference: """I figure that learning about Python and Zope has already paid for the conference. We were going to buy product X, which costs $10,000, and now I learned about Zope, which is free. It cost my company $10,000 to send me and my buddy here, so they're coming out even."""

Printing from Zope
by Felipe E. Barousse Boue 24 Mar '00

24 Mar '00

Hello all: Not sure if this has been asked before, probably yes, but haven't been able to find anything yet. Does any of you has been able to print from a Zope application to a printer attached to the same machine where Zope is running, in my case it's a Red Hat Linux 6.1 box. I need to print from Zope with a specific printing format (like invoices, receipts, etc). This will be done on always the same Intranet and printing will be controlled from the Linux spooling system. If you can copy your comments to me by email besides the mail list, it'd be great. ,Any help is appreciated, thanks in advance. Felipe Barousse

Indirect calling of extensions?
by Glenn Rogers 24 Mar '00

24 Mar '00

Imagine I have a python extension, with zope id pyFetch def Fetch (self, href): ... I want to call this in a manner similar to:      But I get an error: Error Type: TypeError Error Value: not enough arguments; expected 2, got 0 So it seems to evaluate and call the extension without adding the parameters. I guess I need something like lambda in python. Can anyone help me please? Thanks, Glenn

Hello, I intend to get from fatbrain the e-matter edition of the Learning Python book. Can someone comment their experience with this format? The problem is that they mention that e-matter works only on windows platforms, and I want to know if it is possible to print the book so that I can use it while working my computer, which does not run windows.

How to serve php from within Zope
by Andres Corrada-Emmanuel 24 Mar '00

24 Mar '00

Hi, I'm using Apache to serve my Zope pages. I want to serve up some PHP scripts as part of a page wrapped with Zope methods. How do I serve the contents in the /some/other/directory/for/PHP/scripts from within Zope? For example, I want to call index.php3 from within the index_html of a Zope folder and have the contents included in the place I make the call. Andres Corrada
