Variable sort in dtml-in
by Aaron Williamson 14 Jul '00

14 Jul '00

In my search form, I have a selection box "in_sort_by" whose value can be "Category", "Field", or "Title". I am trying to make dtml-in sort by this value. I am using: <dtml-in SQL_search sort="_['in_sort_by']" size=list_size start=query_start> And I've tried other variations, but I always get an attribute error. The strange thing to me is that list_size is also a variable and it works fine, but I've tried just using in_sort_by and that doesn't work. What am I missing here? Many thanks, Aaron

HTMLFile from within a method?
by Rob Miller 14 Jul '00

14 Jul '00

Greetings. I'm a fairly experienced Python programmer, but am new to Zope. I'm working on a Python product, and through this process I'm learning my way around the Zope innards. I'm running Zope 2.2.0b3 on an RH6.1 box. By declaring a class member that is an instance of the HTMLFile class, I can publish dtml files. This is right out of the "Boring Product" How-To; it looks like this: ---------------------- class Product(Implicit, Persistent, RoleManager, Folder): index_html = HTMLFile('index', globals()) ---------------------- Then when I browse to an installed instance of my Product, I'll see the appropriate output generated by my 'index.dtml' file, which is in the same directory as my Product's python modules. What I'm having trouble doing is something similar but from within one of my Product class's methods. I've tried this: ---------------------- class Product(Implicit, Persistent, RoleManager, Folder): def form_handler(self, REQUEST=None): return HTMLFile('form_results', globals()) ---------------------- This causes the output to be munged, like so: <dtml-var standard_html_header> <dtml-in "REQUEST.keys()"> ... and so on ... I've also tried: ---------------------- class Product(Implicit, Persistent, RoleManager, Folder): form_results = HTMLFile('form_results', globals()) def form_handler(self, REQUEST=None): return self.form_results() ---------------------- This causes zope to attempt to publish the object, but the object (my DTML method, stored in "form_results.dtml") doesn't seem to have access to the Product's namespace. That is, I get an error like: Error Type: KeyError Error Value: standard_html_header ...even though there's definitely a standard_html_header defined. Finally, I've tried this: ---------------------- class Product(Implicit, Persistent, RoleManager, Folder): def form_handler(self, REQUEST=None): dtml = open('lib/python/Products/Product/form_results.dtml', 'r') s = dtml.read() dtml.close() return s ----------------------- This causes the right data to be passed out, but it's not treated as dtml. A garbled version of my output appears in the browser window, and if I view source I see: <html><head></head> <dtml-var standard_html_header> <dtml-in "REQUEST.keys()"> ... and so on ... I know there are other ways to accomplish what I'm trying to accomplish, but I really want to understand what's going on here. Can anyone enlighten me as to why I'm seeing the results I'm seeing? Does anyone have suggestions for an appropriately Zen approach to publishing dtml files from within a Product's methods? Thanks for your time, rob

Re: [Zope] Linux user group

Curtis, I 'run' the LiBC --Linux in Boise Club--- and the website(s). We run Zope. You can show them: http://www.libc.org http://theigloo.libc.org As examples, and I might be able to be talked into converting one or two of them into CDROM demos... Though they are both being migrated to 2.2, and improved in the process. ---note: the first URL is a ZEO server ;-) hmmm... somthing tells me ZEO on a CDROm could be righteous.... -- Do not meddle in the affairs of sysadmins, for they are easy to annoy, and have the root password.

Still Problem with LocalFS
by Jorgen Gardsted Jorgensen 13 Jul '00

13 Jul '00

I have had a similar problem. My solution is based on an external method. I have a folder named localFS with 1) a Local File System named images pointing somewhere in file system. 2) an ExternalMethod called addFile looking like this: def addFile(self, file, fullpath): outfile = open(fullpath, 'w') outfile.write(file.read()) _______ the Upload form has this input: <INPUT TYPE="file" NAME="file" SIZE="25" VALUE=""> ________ the action-method looks somewhat like this. <dtml-call "REQUEST.set('fullpath',localFS.images.getProperty('basepath'))"> <dtml-call "REQUEST.set('imgresult',localFS.addFile(file,fullpath))"> ________ This is all very new to me. The file is there, and I can read it, so it should work, I guess. There's no error checking though, so be careful. I also intend to let the external method return something meaningful instead of None. best regards Jørgen

Lucas, If you don't know of a reason you would need Apache, you don't need it. :-) Zope does not directly handle PHP tags. -----Original Message----- From: Lucas Young (c) [mailto:lyoung@sapient.com] Sent: Thursday, July 13, 2000 6:44 PM To: 'zope(a)zope.org' Subject: [Zope] Newbie: Zope a webserver? Serving PHP and Perl Hi Have just installed Zope under Win2K and it works fine - I see a lot of people mention using Apache to server Zope, but isnt Zope a webserver itself? I can browse to http://server:8080/ and view Zope pages, so why would I need Apache? Also, How do I set Zope up so it handles PHP tags? thanks in advance Lucas Young

Re: Re: [Zope] LocalFS Documentation
by Kelvin Cheong 13 Jul '00

I'm puzzled...there isn't any upload at the bottom of the page...but there has always been an upload at the top of the page in the Zope content management interface (along with "Contents", "Edit", "View", "Properties"...etc). If you're talking about, the bottom of the page, there is only an Available objects selection list and an "Add" button. Perhaps it would be better to let you know that I just installed LocalFS, and am very new to Zope. And frankly, I don't even know where to start with the LocalFS product i have installed. The only thing i've done with it so far is add it into my Zope management console from the Available Objects list. Btw, just to fill you in, I'm using Zope 2.1.6 and LocalFS 0.9.4 (could it possibly be the versioning that makes the difference ??).

Blank Date Field?
by James W. Howe 13 Jul '00

13 Jul '00

Is there some easy way to allow for the storage and display of an empty/blank date field? It seems that you are unable to enter a blank value if you defined a property field as storing a date value. I want to be able to store dates in my object, but the date value is optional. Any tips would be helpful. James W.
