[Zope] variable propagation

2006-07-24 Thread Pavel Zaitsev
Hi,
I would like to ask how to propagate variables from initial index_html
call to deeper levels. Say I have index_html python script, I invoke it
then I would like to feed some data to generic template, that will in
turn will invoke template in the same directory that will do nice layout
of my results. Generic template lies below all other objects, in
directory tree, in the root.
When I execute the command chain, variables are not passed and options
is lost on one layer of zpt calls. Is there way to rectify that.
Thanks
Pavel

Pavel,

You question is a bit vague but ...

Make your index_html a python script.  And then stuff your REQUEST with 
info you want


Then just call the Page Template ...

request.set('formvar1', somevalue)
return context.myPageTemplate(context.request)

Of course of you have forms submit with an action=. and method=post.

Then you can intercept all calls using index_html, do what you need to 
do and *then* render the next form.

here is description:

root/
index_html
index_tmpl -- invokes here.content_html
 
root/some/web/page
index_html  -- overriding root one, calls --   context.index_tmpl(some
parameters=some parameters).
content_html -- gets called from index_tmpl

So i want parameters that are presented to index_html be presented to
context_html just like they would be presented to index_html.
So i would be able to call context_html from outside as well from the
inside. Ie span tal:replace=username/ should work in both
cases. I thought thats the way zope's code reuse works.

Pavel,

How are you invoking templates?  Give code snippets.  

Have you read the "Advanced Scripting" section in the Zope book? 
Plope.com has a the latest version (i think).

[Zope] variable length forms...

2000-11-07 Thread zope

Hi.

I have tried to implement a variable length form.

Yes, I have read 
http://www.zope.org/Members/jpenny/variable_length_forms/index_html.!

I a form, I'm using following form fields:

dtml-in "_.range(1, _.string.atoi(form_numpages)+1, 1)"
tr align="center" valign="middle"
tddtml-var sequence-number/td
tdinput type="text" name="form_time_out" size="6" 
maxlength="4"/td
tdinput type="radio" name="radiobdtml-var sequence-number"/td
tdinput type="radio" name="radiobdtml-var sequence-number"/td
/tr
/dtml-in

where form_numpages is a variable that i got from a previous form.
This form works fine and generates me form_numpages lines with always one 
textfield and a group of 2 radiobuttons named per line.

form_time_out  radiob1   radiob1
form_time_out  radiob2   radiob2
form_time_out  radiob3   radiob3
...

The contents of this form is submitted and I want to interpret the data 
with following method:

1: dtml-in "_.range(1, _.string.atoi(form_numpages)+1, 1)"
2:  dtml-var sequence-number:
3:  dtml-var "_['radiob'+_['sequence-number']]"
4: /dtml-in

This returns the following Zope error:

Error Type: TypeError
Error Value: illegal argument type for built-in operation

If I'm replacing the third line with dtml-var "_['sequence-number']", the 
sequence-number is printed out. So I'm sure that it exits.

How can I get the contents of radiob1, radiob2, radiob3, ...

Thanks a lot for your help!

[Zope] Variable name use in with statement

2000-10-13 Thread Burchill, Scott B.

I'm working on a simple auction site as a newbe challenge.  I am taking bids
on three static items, none will be added or removed.  I have a folder named
bid_records in which there is a folder for each item.  These item folders
have current bid information in properties and bid history in ZClass items
stored in them.

When I'm working with a specific auction item I have the name of the folder
in a REQUEST variable.  I am finding myself doing the following and am sure
there is a simpler way to do this.

Any help would be greatly appreciated!  Thanks.

dtml-with bid_records
  dtml-if "_.str(REQUEST.form['selection']) == 'walkon'"
dtml-with walkon
  dtml-call "REQUEST.set('cur_bidder', bidder)"
/dtml-with
  dtml-elif "_.str(REQUEST.form['selection']) == 'fullhouse'"
dtml-with fullhouse
  dtml-call "REQUEST.set('cur_bidder', bidder)"

 dtml-in user_select

If you are sure, that only these values can occur in
"selection" (as I expect, as otherwise, it would not be a selection),
then you can use:

dtml-call "REQUEST.set('cur_bidder',_.getitem(REQUEST.form['selection']).bidder)"

Re: [Zope] Variable sort in dtml-in

2000-07-14 Thread Adam Karpierz

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

Hi Aaron again

I have attached appropriate patch for dtml-in tag for Zope 2.2.0b3/b4
(Of course this patch was checked and works ok).

Just for you, the syntax of my patch for dtml-in should be:

dtml-in SQL_search sort="expr:_['in_sort_by']" size=list_size start=query_start

or best and simply (and strict equivalent above):

dtml-in SQL_search sort="expr:in_sort_by" size=list_size start=query_start

I want extend my proposal to others attributes like eg. size:

dtml-in SQL_search sort="expr:in_sort_by"
  size="expr:REQUEST.user_list_size" 
start=query_start

It is possible easy extend other DTML tags through the same way  too,
but I dont know what other zopistas (especcially from DC)  thinks about this.

My syntax proposal is one which not caused serious comtatibility problems.
Eg. natural syntax attr="something" is treated (unfortunately) as attr=something
and therefore would not be adapt and apply for indirect lookup of attribute
without breaking of compatibility.

Very please all for comments.

 I have attached appropriate patch for dtml-in tag for Zope 2.2.0b3/b4
 (Of course this patch was checked and works ok).

Thanks again for the patch.  It is a much needed option (and rather a glaring omission 
from
the original code).  So far it is working flawlessly for me.

 I want extend my proposal to others attributes like eg. size:

 dtml-in SQL_search sort="expr:in_sort_by"
   size="expr:REQUEST.user_list_size" 
start=query_start

Is this necessary?  I actually use a variable for size (size=list_size) in the same 
dtml-in,
and that part seems to work just fine.  Maybe mine is a special case, but I don't 
think so.

 It is possible easy extend other DTML tags through the same way  too,
 but I dont know what other zopistas (especcially from DC)  thinks about this.

I for one am for it.  The lack of multiple and variable sort keys in version 2.14 were 
a major
hindrance to me.  I am sure that many tags could benefit from similar improvements.

Thanks again,

Aaron

[Zope] Variable sort in dtml-in

2000-07-13 Thread Aaron Williamson

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

[Zope] Variable which delivers the author of an document

2000-05-23 Thread Stefan Pöhnlein

I would like to know,if there is a Variable, which delivers as value the
author of a document, similiar to "AUTHENTICATED_USER", which delivers
the user name.

I couldn't find anything about it in the Zope DTML Reference.

Thanks a lot in advance,

Stefan
