Subject: [albatross-users] Links to related projects
Message-ID: 

Hi,

	I'm going though and cleaning up my little axe project
(http://axe.pseudocode.net), and was wondering if linking to this from
the Wiki was a good idea or not; and if so where to link it in.  At one
time it was talked about having a related links section on the albatross
site, but that's up to the object craft guys =).

	Also, I just may (being XMas and all) go though the TODO list of
11pre2 and knock out those items (esp. since most have my name beside
them, lol).  Before I start, is 11pre2 the latest or is there a CVS copy
I can get at I should work from?

Thanks,
Mike

Subject: [albatross-users] Patch to 1.11pre2
Message-ID: 

I went though the TODO list with 1.11pre2 and fixed the items I
reported:

*  is confusing. Consider having ctx.req_equals()
  check for "name.x" if "name" doesn't exist? Should at least mention
  it in the section of the manual that talks about tags (Michael C.
Neel).

---> ctx.req_equals() will return true for input type=image with only
the name given

* Allow multiple Cookie values to be set (Michael C. Neel).

---> Biggest change made here.  The headers mixin now keeps a list of
values for each header, which also means get_header returns a list.  I
opted for get_headers to always return a list as it's consistent, but it
could be changed to only return a list on more than one value to remain
backwards compatible.  Also, this does not work with the httpdapp.py
request class, as it keeps headers as a dict internally so doesn't
handle duplicate keys.  the apacheapp.py was changed to use the add(key,
val) method of mod_python to handle the dupes.

* ctx.add_session_vars() should create non-existent varaibles with value
  of None (Michael C. Neel).

---> Does just that now.

* Second submission of form will return ctx.req_equals() TRUE for empty
  fields (Michael C. Neel).

---> I couldn't get this to occur on 1.11pre2, so I consider it fixed =)

The patch is against 1.11pre2.  All feedback, comments, flames welcome.

Thanks,
Mike

After some thought, I've added a method ctx.add_header.  Add_header
appends the header to the list, set_header replaces keeping it's same
behavior.  Otherwise you would have to del_header before every
set_header for 95% of headers.  This way you just add_header when you
want more than one header of the same name.

This is a resend of the complete patch again, to be patched against
1.11pre2.

Thanks,
Mike

Subject: [albatross-users] Trouble with custom tag
Message-ID: <01d401c3cdb6$e00c72c0$c100a8c0@CLAPTON>

I'm trying to create a custom tag that wraps it's contents in some flash
sniffing javascript.  The contents of the tag need to be executed as
normal, as they could contain other albatross tags, and to do this I'm
calling the Content's to_html method.  The Context class however is set
to write to sys.out, and I need to stop this because I need to alter the
results.  Here is what I'm trying:

import albatross, copy

class NoFlash(albatross.EmptyTag, albatross.tags.EvalAttribMixin):
    name = "alx-noflash"

class Flash(albatross.EnclosingTag, albatross.tags.EvalAttribMixin):
    name = "alx-flash"

    def __init__(self, ctx, filename, line_num, attribs):
        albatross.EnclosingTag.__init__(self, ctx, filename, line_num,
attribs)
        self.flash = self.content
        self.noflash = albatross.Content()
        self.noflashseen = 0

    def to_html(self, ctx):
        dummy = copy.copy(ctx)
        dummy.send_content = send_content
        self.flash.to_html(dummy)
        self.noflash.to_html(dummy)

    def append(self, tag):
        if isinstance(tag, NoFlash) or self.noflashseen:
            self.noflash.append(tag)
            self.noflashseen = 1
        else:
            self.flash.append(tag)

def send_content(data):
    assert 0, data
    pass

My assert is not going off.  If I don't do a copy.copy it will go off
correctly, but since it's a reference I just killed the real
send_content, and that's bad.

Any thoughts?

Okay, I'm an idiot, I look right past the push/pop content trap
functions.  All I needed was is this:

    def to_html(self, ctx):
        ctx.push_content_trap()
        self.flash.to_html(ctx)
        flash = ctx.pop_content_trap()

        ctx.push_content_trap()
        self.noflash.to_html(ctx)
        noflash = ctx.pop_content_trap()

        ctx.write_content(flash)

Subject: [albatross-users] pagination with al-for
Message-ID: <696013985.1072829688@lsanca1-ar1-4-62-158-245.lsanca1.dsl-verizon.net>

Hello,

I've set up a portion of my app that displays some log results with
pagination (assuming that there are more log entries than the page size
I've set).

It wasn't too hard to get the prevpage/nextpage links working, so that I
can page forward or backward through the entire sequence display.

However, I like to be able to jump directly to a particular page.

For example, if pagesize is 6, and there are 26 entries, and thus 5 pages...

How would I best display a list of page numbers so that I can click
directly on a given page number and go to that list of six items?

I started to think maybe I need to go to trees for this? 

Well, hoping for tips or suggestions.

Thanks,
