You're not missing something - Albatross doesn't do this. I wonder what PHP is doing?

As I speak, Debian mirrors around the globe are updating and you should be able to apt-get the package in no more than a few hours. Python 2.2 and 2.3 versions are provided, with 2.2 being the default. Installation Please refer to the APT documentation on how to add the neccessary lines for Debian unstable to your sources.list file. Then, you can apt-get install the following: python-albatross -- the current default version (choose this if unsure) python2.2-albatross -- the version for python 2.2 python2.3-albatross -- the version for python 2.3 The packages contains the latest stable version of Albatross (1.10). I'm preparing to release a newer version as soon as a new stable version is released. Reporting Bugs Please use the Debian Bug Tracking System to report bugs in these packages. If the bug is in Albatross itself rather than in my packaging, then consider reporting the issue to Object Craft as well. Known Bugs I know that there are some issues with the packages that may be inconvenient for some people. They don't affect the functionality of albatross. Please don't report these, they will be fixed in an upcoming release, or I have decided not to support those features at the moment. Feel free to discuss them publicly on the mailing list or in private email to me. * There is no python 2.1 version. I don't intend to supply one unless there is demand for it. (And then, the only argument that I buy would be that you have an existing albatross application that uses some feature unique to python 2.1.) * There is no documentation package. This is because a known bug in the dia diagram drawing program prevents generation of the diagrams in the documentation. The bug has recently been fixed, but it will take some time before a new, fixed version of dia will be available. * You will always get the session server and standalone application server, and you can enable a system-wide session server by editing the defaults file in /etc/defaults/albatross. I recently merged the separate session and application server packaged back into the main package because they are so small. A future version of the packaging may see a different kind of split. * The test suite is not run at build-time. This will require some rather large changes to the test suite to support both python 2.2 and 2.3. While it would certainly be nice to run the tests automatically at build time, I do run them manually and make sure they pass before releasing a package. I hope you will find the Debian packages useful, and I welcome bug reports, feedback and patches warmly. Finally, thanks to the Object Craft people for making Albatross!

That's my only defense :) Anyway, just a quick note for those who are not familiar with the Debian release process: new and updated packages always enter "unstable" first. At regular intervals, they are automatically moved to "testing" if they satisfy some quality requirements. Finally, the packages in "testing" will be frozen at some point and become the next "stable" version. So being in Debian unstable is not neccessarily an indicator of the quality of Albatross! As a side note, perhaps Andrew and Dave could comment on the time-frame of making a new stable release? > On a serious note, good job for making this happen!

An example would be taking the output of a perl cgi script and formatting it with albatross. To make this work, I've written a quick apacheapp Filter class, which works just like a request class. Filters are limited in what they can do, so there is a lot of pass statements. In pratice, this would work just like a Request class, ie. app.run(Filter(filter)) - filters are not passed the request object, but a filter object. There should be anything in here to change, but it is a first cut, so apply with caution. It is intended to be placed in the apacheapp.py file with the Request class for mod_python. Mike class FilterRequest(RequestFields): def __init__(self, filter): self.__req = filter.req self.__filter = filter RequestFields.__init__(self, util.FieldStorage(self.__req)) self.__status = 200 def get_uri(self): return self.__req.uri def get_path_info(self): return self.__req.path_info def get_servername(self): try: return self.__req.hostname # mod_python 3 except AttributeError: return self.__req.connection.server.server_hostname # mod_python 2 def get_header(self, name): if self.__req.headers_in.has_key(name): return self.__req.headers_in[name] def write_header(self, name, value): pass def end_headers(self): pass def redirect(self, loc): pass def write_content(self, data): self.__filter.write(data) def set_status(self, status): self.__status = status def status(self): if self.__status == 200: return 0 return self.__status From neel at mediapulse.com Sat Feb 21 03:21:55 2004 From: neel at mediapulse.com (Michael C.

Message-ID: I've come across a strang which is in 1.11+, maybe prior versions as well but I didin't check them. Normally, if you try to have several form fields defined with the same name, you either need to use the "list" argument on the tags, or make the list in the page object/module. This is very nice, because albatross doesn't pull an perl like bs of thinking for you, and letting some bug creep into production because it never caused a problem when testing. However, if you name several fields the same name, but they are different types, you can get a field that will sometimes be a list, sometime a string. To show this, here is a simple template that will show the problem: Select1 Select2 Select3 Select4 Select5
Radio1
Radio2
selbox: if you just submit, selbox is a string og the select box choice. If you also select a radio, selbox is a list of the select box choice and the radio choice. If you change either of the radio buttons to checkboxes you will get the (excpected) traceback error that selbox is not defined as a list. Normally I would dig into the source to find out what's going on, but since I'm pressed for time I thought I'd just send this now and if need be I can dig deeper later.

I tend to agree - 2.1 seems to have been bypassed - I think the people who were stuck with old applications stayed with 1.5.2, then jumped directly to 2.2. 2.2 is more stable than 2.1 without breaking too much, and I think 2.3 will prove to more stable again. > * There is no documentation package.

This is a hard choice (it should only be the doc tests that fail) - there may be ways of solving it, but they won't be pretty. I'm a little reluctant to make the test harness more complicated because I worry that bugs will creep in. BTW, I think I updated the doc tests to 2.3 output in the latest snapshots. -- Andrew McNamara, Senior Developer, Object Craft http://www.object-craft.com.au/ From korg at darkqueen.org Tue Feb 24 20:25:09 2004 From: korg at darkqueen.org (Cameron Blackwood) Date: Tue, 24 Feb 2004 20:25:09 +1100 Subject: [albatross-users] al-input type="image" with variable src Message-ID: <20040224092509.DD7FB534DE@firewall.darkqueen.org> Hi everyone! its been ages since Ive had time to play with albatross, but im at it again.... and sadly my albatross brainspace has rusted shut. :( Im trying to make an array of graphic buttons, each clickable.

Hmm, al-input does not have a srcexpr attribute so it's not going to be as nice as it could be. However, something like this (untested) should work: " name="button-at" value="3,4" /> I assume foo is some function you have made available in the context. Alternatively, you could write a custom tag that understands a srcexpr attribute. There's a custom tag example in the wiki and albatross.tags is fairly straightforward. > > I guess I could wrap a whole lot of 's in 's, but id > really rather not.

The solution is to extend Albatross to provide a mechanism to evaluate any attribute, so you could do something like: Unfortunately, that doesn't help you.

I tried "_." but then I remembered that was a zope thing, or atleast from somehere weird inside my rotting brain. So I ended up with: and albatross code to do: if ctx.get_value('newpos'): p=ctx.get_value('newpos') if p[0]=='(' and p[-1]==')': sp=string.split(p[1:-1],',') if len(sp)==2: x=string.atoi(sp[0]) y=string.atoi(sp[1]) ctx.locals.design.view_move(x,y) ctx.locals.msg='Moved view by %s,%s to %s
\n'%(x,y,ctx.locals.desig n.pos) Which isnt very safe, input wise, but its just a hack until I get something else worked out (or im brave enough to try adding srcexpr to albatross :) Actually, that does raise another question, im on albatross-1.10.tar.gz if I was going to try to add srcexpr, then which version of the code would it be best to do that to? -- / `Rev Dr' cam at darkqueen.org Roleplaying, virtual goth \ < http://darkqueen.org Poly, *nix, Python, C/C++, genetics, ATM > \ [+61 3] 9809 1523[h] skeptic, Evil GM(tm).

Unless the parsse can be written in such a way that an al- pre fix is picked up like Andrew write. Though al- there might be confusing, I'd go with either: anything ending in expr or (my preference) anything leading with an underscore: _src="'foo(%d,&d)' % (3,4)" Mike From gabriel.cooper at mediapulse.com Thu Feb 26 02:42:31 2004 From: gabriel.cooper at mediapulse.com (Gabriel Cooper) Date: Wed, 25 Feb 2004 10:42:31 -0500 Subject: [albatross-users] al-input type="image" with variable src In-Reply-To: References: Message-ID: <403CC267.9020601@mediapulse.com> Michael C.

Typical size might be 20 rows by 5 columns, and maybe 20% of the squares would need to be entered. (If it helps, the entries should all be integers > 0). I'm struggling to find a natural way to handle this in Albatross. My first cut did something like this: etc This has 3 problems, more or less, as it stands: - Finding out which cells are entered is awkward: for r in range(rows): for c in range(cols): v = getattr(ctx.locals, 'r%dc%d' % (r, c)) if v: # Do stuff # may need to be "v is not None" depending on blanks etc - If I discover an error in the page_process() (i.e. mis-typed cell contents), then redisplaying the page without navigating to a new one blanks all the cells. This is a surprise..... and a pain if if forces a bunch of re-typing. It seems the "fill in the default value from ctx.locals" is not working for al-input when nameexpr is used instead of name? - (this is a web problem more than an Albatross problem...) When typing in a cell, the browser keeps "helpfully" suggesting possible completions in little tool-tip-like boxes. This is a HUGE PITA. Any clues or ideas?

I'm going off of the general idea here, you'll have to adapt it, but say it's a 3x3 grid. If we can number each box 1-9 and assume a setup like: 123 456 789 The first we setup a box class, with an albatross alias: class Box(object): def __init__(self, position): self.postition = position self.value = '' def albatross_alias(self): # this must be unique # in a pinch, you can do some id() and time() trickery to make up # a unique value return self.position ... Then in our page module populate a list ... ctx.locals.boxes = [] for i in range(1,10): ctx.locals.boxes.append(Box(i)) ... Then in the template ... ... And back in the page module on submit ... for box in ctx.locals.boxes: do_something(box.value) Mike > -----Original Message----- > From: albatross-users-admin at object-craft.com.au > [mailto:albatross-users-admin at object-craft.com.au] On Behalf > Of Gregory Bond > Sent: Friday, February 27, 2004 1:31 AM > To: albatross-users at object-craft.com.au > Subject: [albatross-users] Need some hints on: filling in a grid > > > I have an application where the user needs to fill in some > entries on a grid. > Typical size might be 20 rows by 5 columns, and maybe 20% of > the squares would > need to be entered.

There's an upcoming version of the package which fixes some issues. That version will default to python 2.3 since it's the next default version in Debian. > Dia. Sigh. I believe the next release of Dia will have addressed the issues you've had with it.
