[Zope] How to display image returned from Catalog query

2001-01-30 Thread Timothy Wilson

Hey everyone,

I've got a PythonScript that returns a list of 'Photo' instances. I'm using

dtml-in returnPOTD size="1" orphan="0"

to grab the first instance off the list.

What I can't figure out is how to display that image. I can use

a href="dtml-absolute_url;"dtml-var title/a

to make a link to the image, but I want this method to display the image
directly.

dtml-var sequence-item returns the instance itself and doesn't display
anything. I'm sure there's something simple I'm missing here. Any
suggestions?

-Tim

Doh! I was trying to do too much with DTML. Thanks for the tip!

Re: [Zope] Is it possible to use regular CGI's like htDig withzserver?

  And if so, how would I set that up?
 
 -Use Apache as your main server.
 -Use mod_proxy(?) to proxypass Zope requests through to ZServer.
 -install htdig as a normal CGI under Apache

Presumably, then, this would be the same approach for getting Mailman
working alongside Zope?

 I don't know where it would be in the book it would be, but
 I do this something like::
 
   dtml-in expr="theCatalog( meta_type='Photo'
, display_date=ZopeTime()
, display_date_usage='range:max'
, sort_on='display_date'
, sort_order='reverse'

 The expression would be basically the same in a PythonScript::
 
   return context.theCatalog( meta_type='Photo'
, display_date=ZopeTime()
, display_date_usage='range:max'
, sort_on='display_date'
, sort_order='reverse'
)

Great! The first DTML example works perfectly. The second, however, throws
up an error. In fact, I have yet to figure out how to use ZopeTime() in a
PythonScript. Do I have to pass anything in? 

I get:

Error Type: NameError
Error Value: ZopeTime

when I try it.

 Hope that helps!

Thanks again. I should have those pictures up in no time.

[Zope] PythonScript question

2001-01-27 Thread Timothy Wilson

Hi everyone,

I'm using the Photo product to diplay some pictures at various resolutions
and to display them on a certain date. (Some may recall my questions about a
"Picture of the day" recently.) I want to set a 'display_date' property for
each Photo instance and I'd like to do it using a PythonScript. I've created
a form and PythonScript, but I get this error:

Error Type: TypeError
Error Value: argument 1: expected read-only character buffer, instance found

and this traceback:

And here's my PythonScript 'POTD_add' to which I pass the parameter list 
'title, display_date, and file':

"""
Create a "Picture of the Day" image.
"""
import string

# create a unique object id based on the display date
newID = string.split(display_date, '/')
id = ''
for i in newID:
  id = id + str(i)

# create the image
context.manage_addProduct['OFSP'].manage_addPhoto(id, title=title,
file=file)

# add a display date property
doc = getattr(context, id)
doc.manage_addProperty('display_date', display_date, 'date')

Any ideas?

Wouldn't it would be great if there was a PythonScript repository
somewhere? It would help me a ton.

At the bottom of the page there's a link called "View Source" which will

You're right. It's very handy.

[Zope] batch processing problem

2001-01-20 Thread Timothy Wilson

Hi everyone,

I was trying to throw together a page with some pictures of my brand-new
nephew for his parents to show to relatives. What should have been a
relatively simple dtml-in iteration through a folder full of images has
turned out to be headache inducing. I'm sure that there's something I'm just
not understanding, but I can't figure out why the following doesn't
work. I've tried many different combinations without success. You can see it

 Subclassing Image might be useful, but you could certainly
 get by without if, if all you need is to add a property or
 two:  Images have a propertysheet to which you could add them.

But if I use the standard Image meta type, wouldn't I have to create a
'display_date' property by hand each time I upload an image? I suppose it
would be possible to create an HTML form that would add that property for
me. I'm not sure I want to catalog every image on my site so another for
creating a separate product would be that I could make it catalog-aware on
its own. Comments?

[Zope] Picture of the day product

2001-01-17 Thread Timothy Wilson

Hey everyone,

I was looking at linux.com the today and I noticed their "Daily Photo." I
occurred to me that that would be a fun addition to the school's page that
I'm developing. My first thought would be to:

* inherit from Image
* add caption, date taken, etc. properties
* create an archive of past photos

What I'm not sure about is how to have Zope automatically display the photo
for a day, then archive it. Would a boolean property of the ZClass work? Is
it possible to have Zope set the property of a ZClass instance at certain
time? Any thoughts on how this would be designed?

Re: [Zope] ZClasses meet PythonScripts, sample request

2001-01-15 Thread Timothy Wilson

Jim (or anyone else who's feeling charitable this morning),

Thanks for all your help. I really appreciate it. I wonder if you'd have
time to look one more time at the two methods I've got that aren't
working. I've included the actual code for my job posting product. Perhaps
someone will find it instructive. I have a feeling that the remaining
problem is not directly related to the processing of the form by the
PythonScript. I also included the traceback at the end of this message.

Here are the two methods. I have a table that displays the currently
available jobs and displays two little icons which call the edit or delete
methods on the corresponding instance of the 'Job Posting' class. The edit
icon links to the 'editJobForm' method which in turn calls the
'editFormAction' method that actually processing the change.

Thanks Jim.

Care to elaborate on the problems with using id as a form variable.

Re: [Zope] ZClasses meet PythonScripts, sample request

2001-01-15 Thread Timothy Wilson

On Mon, 15 Jan 2001, Jim Washington wrote:

 What is the name of the propertysheet in your ZClass that these values
 are on?  Is it 'job_info'?

Yes.

 Where is the editFormAction Python Script? It should be in your ZClass's
 /methods.  If you are instead acquiring it from a Folder somewhere, you
 will need to use 'context' instead of 'container' inside the Python
 Script.

I had them originally in the ZClass's /methods, but moved them out.

That brings up another good question that I haven't really seen
addressed. Hopefully others are still reading this thread. :-)

When is it proper to make your methods part of the ZClass itself and when
should I put them out in a folder somewhere to be acquired? I've seen it
done both ways in various products, but the difference between the two
approaches has never been completely clear to me.

Can anyone suggest a "rule-of-thumb" here?

[Zope] How to display only x records with dtml-in

2001-01-15 Thread Timothy Wilson

Hey everyone,

I've got a method to display some text which uses 
dtml-in "objectValues(['Spam and Eggs'])"
to iterate through a bunch of "Spam and Eggs" ZClass instances. I thought
that I could use size="2" in the dtml-in to display only the first two
instances, but it's not working. I want to display only the first two and
use a link at the bottom to direct people to see the rest on a separate
page. Any ideas?

Re: [Zope] ZClasses meet PythonScripts, sample request

2001-01-14 Thread Timothy Wilson

On Sun, 14 Jan 2001, Jim Washington wrote:

 You probably want the work to be done in the context of an instance of
 the class, so assure you have "context" bound to the Python Script on
 the "bindings" tab.  It's bound by default.
 
 You might want to name the Script in a Zopish way to distinguish it from
 other scripts that may do other things.  I would probably call it
 manage_changeCDProperties.
 
 You will want to pass REQUEST to it so you can use it like the Zope
 builtins:
 
 containerName.CDInfoName.manage_changeCDProperties(REQUEST)
 
 So, put REQUEST in the parameters list.

I'm afraid I'm a bit confused here. Is 'CDInfoName' the id of an instance of
this CD class? If so, what would 'containerName' be?

In the particular example I'm thinking about (not a CD collection), I've
created a form that displays the current properties of the class (a job
opening for the H.R. deparment in my case), allows the user to modify any of
the properties in the form, and submit those changes. I suppose for the CD
example it would something like: (ignoring everything but the form)

form action="manage_changeCDProperties(REQUEST)"
table border="0"

trthTitle/th
  tdinput type="text" name="title" value="dtml-var title"/td
/tr

trthArtist/th
  tdinput type="text" name="artist" value="dtml-var artist"/td
/tr

trtd
input type="submit" value=" Submit Edits "
/td/tr
/table
/form

I don't think I'm calling the PythonScript correctly. In fact, I suspect I'm
quite a bit off.

 Inside the script, you would use Zope's manage_changeProperties method:
 
 context.propertysheets['cd_info'].manage_changeProperties(REQUEST)
 -or-
 context.propertysheets.cd_info.manage_changeProperties(REQUEST)

Following Evan's advice, would this then be:

container.propertysheets['cd_info'].manage_changeProperties(REQUEST)

So that's a one-liner? Hmmm. Cool if true. :-)

Let's say that I wanted to redirect the user back to the Web page where they
had begun this process. How would that be accomplished?

[Zope] Design/DTML question

2001-01-10 Thread Timothy Wilson

Hi everyone,

I'm working on a Web page for our local school board. I'd like to create a
table that would display links to past board meeting minutes. The table
would look like this: (Note: dates are bogus)

+---+
| Meeting Minutes   |
|   |
| Monday, Jan. 10  Monday, Mar. 7   |
| Tuesday, Jan. 24 Monday, Mar. 20  |
| Monday, Feb. 7   Monday, Apr. 5   |
| Monday, Feb. 27  Tues., Apr. 19   |
|   |
|1999 | 2000 | 2001 |
+---+

By default, dates for the current year would be displayed, but clicking on
the years at the bottom of the table would display those dates.

Right now, I've got the dates stored in a TinyTable. I can iterate through
that list and generate the links, but I can't figure out how to display the
table in two columns.

dtml-in meetingDateTable
 trtddtml-var meeting_date/td/tr
/dtml-in

will print the dates in a single column, but how can I iterate through and
refer to two different dates in one dtml-in pass? (Does that make sense?)

The second thing I'm tring to figure out is how to make the year links at
the bottom generate the new table of dates from a different TinyTable. Maybe
I should use the same TinyTable for all of the meeting dates and pull out
whichever year I need when the table is rendered.

I'm also wondering if I should implement these meeting minutes and agendas
in a ZClass. At first it seemed like this would be too simple to bother
with, but now I'm wondering if a ZClass would be a better approach. I'd
appreciate any comments.

[Zope] user property sheets

2000-12-18 Thread Timothy Wilson

Hey everyone,

I'd like to make a product so that Zope users' contact info would be
available on a "MemberBio" page whenever you click on a hyperlink of their
name. The MemberBio page would also contain a form that could be used to
send them email.

I know there's been some discussion of property sheets for Zope users, but I
don't know if this would be the correct approach. Should I create something
totally separate, use property sheets, or some combination. The advantage of
a separate product is that the person wouldn't have to exist as an official
Zope user to have a "MemberBio" page. Any advice?

[Zope] Pesky DateTime problem

2000-12-15 Thread Timothy Wilson

Hi everyone,

I would *really* appreciate some advice about a problem with a ZClass I
created. This product is a Job Board that our H.R. department can use to
post openings and the public can view. I began by looking at the very nice
"Build a Searchable Job Board" How-To at
http://www.zope.org/Members/mukhsein/job_board_howto and combined that with
the ZClass approach put forward in the Beehive ZClass documentation.

The problem lies in adding an instance of the job board ZClass at which
point Zope reports an "Invalid Date-Time String". At the risk of providing
too much information, I'm going to include some of the relevant methods and
the traceback. I would love it if someone could spot my error. (Why do I
have this feeling that it's something really simple and that I'm an even
larger moron than my friends and acquaintances assume me to be? :-)

Here the traceback:

 You might have considered this already, but you're not supplying a 
 default date in the DateTime field of the form.  This can cause problems, 
 because there's a bug in zope that won't allow null values in DateTime 
 properties.  

I thought that was only a problem when defining the list of properties
initially. I didn't think you had to supply a default when creating actual
instances of the class.

[Zope] Problem with 2.2.2 and date properties?

2000-10-12 Thread Timothy Wilson

Hi everyone,

I'm having trouble with a ZClass I've created that uses, among others, two
date properties. I'm suddenly having problems creating new instances or
working with existing instances of my ZClass. I can't be sure, but it seems
like the onset of the problems coincided with my upgrade to 2.2.2. Has
anyone else seen any problems with date properties and Zope 2.2.2?

[Zope] Using ProxyPass and SiteRoot

2000-10-11 Thread Timothy Wilson

Hi everyone,

I've read the "Using Apache with ZServer (NOT Zope.cgi)" How-To and I find
that my situation is different enough from the ones described that I'm not
having any luck setting it up. I'd appreciate any suggestions on the
following:

My current Zope site is at http://www.isd197.k12.mn.us/ which uses
Zope.cgi. There are a number of other static, non-Zope virtual hosts running
on that same machine representing a number of our elementary schools.

I've been developing a new Zope site on a separate machine at
http://206.131.108.103:8080/ using just ZServer and I would like to use
ProxyPass to pass a request for www.isd197.k12.mn.us through to this new
site.

Can someone suggest ProxyPass and SiteRoot settings that will make this
work?

[Zope] sudden ZClass breakage

2000-10-05 Thread Timothy Wilson

Hi everyone,

I've been working away on a ZClass-based product that will provide a
searchable job board for our Human Resources Dept. here at school. Things
were going along fine until, it seemed, out of the blue I started getting an
error message about an "Invalid Date-Time String" and a lengthy
traceback. I'm wondering if anyone can glean anything from the
traceback. Is this one of those obvious errors that I'm just missing? I'm
really puzzled. Any advice would be appreciated. Here's the traceback:

[Zope] handling date properties in dtml-if

2000-09-30 Thread Timothy Wilson

Hi everyone,

I've created a simple ZClass to allow our Human Resources dept. to post job
openings on our Web site. There's a DTML method that iterates through a
folder containing all of the 'Job Board Entry' instances and displays them
in an HTML table. No problem there.

The ZClass has a number of properties including two dates, 'date_posted' for
the date that the job is officially available and 'offer_expires' for the
date the job opening officially closes. I want to display only those jobs
for which the current date is on or after the 'date_posted' and on or
before 'offer_expires'. I've tried a bunch of things, but haven't hit upon
the winning answer. Any takers?

[Zope] ZClass for PDFs

2000-09-07 Thread Timothy Wilson

Hi everyone,

I'd like to make a large number of PDF files available for download from my
site. HTML versions of the files will also be available for online viewing.

I could certainly include the PDF files as regular file objects or I could
create a ZClass specifically for PDF files.

I suspect that this question may be of general interest, so I'm asking for
comments about the pros and cons of either approach.

Thanks for the pointer.

It doesn't appear that the ZpdfDocuments is what I'm looking for.
ZpdfDocument seems to render PDF on the fly from structured text or HTML. I
was interested in simply storing an existing PDF file in the ZODB and making
it available for download.

Is there a reason to make a PDF ZClass? Would it make things easier?

If you're running a 2.2.x version of Zope, then the new security model

Re: [Zope] queries and tiny tables and python methods... oh my!

  The problem is hooking them all together. Passing the query to a

 The error means you're trying to split up a string, but the argument is
 no string, but an instance (a Python Object). In many cases this is
 caused by an omission of parenthesis, like so 
 
 called_object instead of called_object()

OK, that makes sense.

 in which case the object is referenced instead of called and nothing is
 returned (of course). I did not find the culprit in your description,
 though. 

 I do not quite get what part you want to parse. Is it 'SB_B208'?
 accessing this in python is a bit strange due to the returned value. You
 get to the 'SB_B208'part in the following way:
 
 whateverreturnstheresult(someargument)[0][0][0], meaning (in this
 case):

I was trying to walk the fine line between providing too much detail and not
enough. Briefly, 'SB_B208' is an example of the type of string I'm trying to
parse. I do a string.split('l', '_') (where 'l' is the argument to the
string-splitting Python method) and get ['SB', 'B208']. 'SB' is one of the
two-letter codes that gets lookup up in the Tiny Table and 'B208' is an
office number. Together, these two strings represent a person's location in
our LDAP directory.

I don't understand where the weird tuple in the traceback is coming from.

  Here's the code for parseLocation ('l' is the argument):
  
  x = string.split(l, '_')
  return x[0]
 
 I may be reading badly, but can you explain what the l is (or is
 supposed to be)? Is it the tuple in the traceback?

'l' is passed to the Pyton Method. Examples would be: FH_123, SB_A231,
DO_111, etc.

  (BTW, changing it to x = string.split(`l`, '_') eliminates the error, but
  nothing is rendered.
  
  qry_person is an ZLDAP filter method that takes one argument (uid). The
  original dtml to display this mess looks like:
  
  dtml-call "REQUEST.set('user_id', user_id)"
  dtml-in "qry_person(uid = user_id)"br
dtml-in "buildingCodes(parseLocation(l))"
  dtml-var buildingbr  # 'building' comes from the Tiny Table
/dtml-in
  /dtml-in

Anyone see where the problem lies?

[Zope] queries and tiny tables and python methods... oh my!

2000-06-29 Thread Timothy Wilson

Hi everyone,

(Please excuse the vague Wizard of Oz reference in the sub., but my brain
may be imploding. :-)

I'm trying to merge several type of Zope objects, and I'm getting lots of
little errors. I wonder if someone could suggest where my problem lies.

1. I'm querying our LDAP server to retrieve the records for a given person
in the directory. No problem there.

2. I'm parsing one of the entries in the LDAP directory to retrieve the
user's location. Python method code is simple.

3. I'm using a Tiny Table to look up a value for one of the parsed strings.
Easy.

The problem is hooking them all together. Passing the query to a
PythonMethod is throwing up the following error:

Error Type: TypeError
Error Value: argument l: expected read-only character buffer, instance found

(BTW, Netscape on Windows doesn't product a traceback, but Netscape on Linux
does.)

parseLocation is a Python Method which takes 1 argument (a string) and 
returns the first element of the list that's formed by splitting the string.
That first element is a two-letter code that's looked up in a Tiny Table
called buildingCodes which returns the full name of the building.

OK, it looks to my relatively inexperienced eyes that the Python Method
isn't getting an argument of the type is expects.

Here's the code for parseLocation ('l' is the argument):

x = string.split(l, '_')
return x[0]

(BTW, changing it to x = string.split(`l`, '_') eliminates the error, but
nothing is rendered.

qry_person is an ZLDAP filter method that takes one argument (uid). The
original dtml to display this mess looks like:

dtml-call "REQUEST.set('user_id', user_id)"
dtml-in "qry_person(uid = user_id)"br
  dtml-in "buildingCodes(parseLocation(l))"
dtml-var buildingbr  # 'building' comes from the Tiny Table
  /dtml-in
/dtml-in

I'd appreciate it if anyone has any ideas about this. I'm probably making
the whole thing too complicated, but for reasons of code reuse, this seemed
like the most efficient approach.

[Zope] parsing strings in DTML

2000-06-26 Thread Timothy Wilson

Hi everyone,

I'm working on what should be a simple problem.

I pulling an address out of an ldap query and the data is in the form of a
$-separated string. Example:

101 Main St.$Anytown$MN$12345

Please correct me if I'm wrong, but I could probably do dtml-call
"REQUEST.set('parsed_address', _.string.join(old_address, '$')" except for
the fact that getting "old_address" (the $-separated one) would require its
own dtml-var old_address statement. I can't nest dtmls so how to I
combine these?

Second question... Once I've got my string parsed into a list called
"parsed_string", what's the syntax for accessing certain elements of the
list?

Thanks.

-Tim

P.S. Maybe I should do this in an external or python method, but I thought
it would be overkill for a single operation like this. Am I wrong?

 I'm not sure I get you right.
 try something like (untested):
 
 dtml-call "REQUEST.set('parse_address', _string.split(old_address, '$')"

You're right, of course, about the "split." A slip of the typing fingers.
:-)

 If you want to know more, you should probably look at the Python docs, as
 this is Python stuff.

Doing this in Python is easy. That's not the problem. I've been struggling
with all of the RESPONSE.set, REQUEST.set, etc. stuff. I can't keep it all
straight. Adding the dtml layer to this really adds to the comlexity of it
all. I just need more Zen. :-)

Thanks for the help.

 for parsing the string

But what if "parse_address" comes from a SQL query? Like this:

dtml-in qry_contactInfo
  dtml-call "REQUEST.set(dtml-var parse_address, ... etc.

Don't I run into trouble with nested DTML here?

[Zope] Attn all Minnesota Zope fans

2000-06-12 Thread Timothy Wilson

Hi everyone,

I'd like to know if anyone else in the Twin Cities region of Minnesota is
using Zope. I've hooked up with a couple other people in the past few
months, and I'm wondering if there's a critical mass of people who would be
interested in a *very* informal Zope SIG. Please let me know (even if you
don't want to be involved in any sort of SIG).

 I was among one of the first to be active in the zope-edu list and I am
 still interested and even working on a product for course maintenance. I
 even sent Shane an immature snapshot, but had to reimplement the product
 because of nesting ZClasses (sigh). Moreover, I was changing jobs as well,
 which did not exactly help in getting things from the ground.
 
 So - yes I'm still interested Shane.

I'm still very much interested in this. School's out in a week or so, and I
plan to work hard this summer worked on developing Zope stuff to be used
here at school. I would love to renew the discussions.
