| mgedmin | you could extract the principal from the current interaction... | 00:10 |
|---|---|---|
| philiKON | well, from one of the participations of the current interaction | 00:11 |
| philiKON | though usually the only participation hapens to be the reuqest :) | 00:11 |
| baldtrol | yeah :\ | 00:11 |
| baldtrol | basically i have a few content objects associated with a principal. the content objects hook back into an rdb, and it's a view on those content objects that need to have the choice widget. but the vocabulary needs "request" in order to seek for the right bits out of the rdb to create the right choice elements... | 00:13 |
| baldtrol | if vocabularies aren't the right way, that's ok too. | 00:13 |

| flox | i see that directive <factory> is deprecated, replaced by <utility> | 10:34 |
| flox | but we still use sub-directive <factory> inside a directive <class> | 10:34 |
| flox | right? | 10:34 |
| *** romanofski has joined #zope3-dev | 10:35 | |
| *** romanofski has quit IRC | 10:40 | |
| philiKON | flox, you can, but you don't have to | 10:40 |
| philiKON | flox, i don't :) | 10:40 |
| *** romanofski has joined #zope3-dev | 10:49 | |
| flox | in ur example, u still use subdirective 'factory' | 10:52 |
| flox | <class ...><factory id="worldcookery.Recipe" title="Create a new recipe" description="..." /> | 10:54 |
| philiKON | well, yeah, my example is also 2 years old :) | 10:54 |
| flox | i know | 10:54 |
| flox | but how i formulate this one differently? | 10:54 |
| flox | i try to remove any deprecation from these exemples (to better understand how things evolve) | 10:55 |
| philiKON | from zope.component.factory import Factory | 10:55 |
| philiKON | recipeFactory = Factory(Recipe) | 10:55 |
| philiKON | <utility component=".recipe.recipeFactory" name="worldcookery.Recipe" /> | 10:55 |
| flox | first 2 lines should be added to "recipe.py", i guess | 10:56 |
| *** alga has joined #zope3-dev | 10:59 | |
| philiKON | flox, exactly :) | 11:04 |
| flox | thks | 11:04 |
| flox | no more deprecation on example from chapter 12 | 11:05 |
| flox | hehe | 11:05 |
| philiKON | flox, :) | 11:05 |
| flox | philiKON: still a problem in zcml file | 11:10 |
| flox | philiKON: it does not accept subdirective <utility> below a directive <class> | 11:11 |
| *** baijum has quit IRC | 11:11 | |
| philiKON | flox, not utility subdirective | 11:12 |
| philiKON | flox, utility top-level directive | 11:12 |
| philiKON | it's just a standard utility | 11:12 |
| flox | but i can link the class to the utilty? | 11:12 |
| flox | or i just repove the class... | 11:12 |
| philiKON | ? | 11:12 |
| flox | s/repove/remove/ | 11:12 |
| philiKON | huh? | 11:12 |
| philiKON | recipeFactory = Factory(Recipe) | 11:13 |
| philiKON | Recipe is the class | 11:13 |
| philiKON | recipeFactory is a factory from the Recipe class | 11:13 |
| flox | ok | 11:13 |
| flox | how i register them in the zcml? | 11:13 |
| philiKON | i just told you | 11:13 |
| flox | the utility is top-level, ok | 11:13 |
| flox | i just keep remove the old <factory> from the <class> and that's all? | 11:14 |
| flox | ok i try this | 11:14 |
| philiKON | flox, have a look at http://www.zope.org/DevHome/Wikis/DevSite/Projects/ComponentArchitecture/ReducingTheAmountOfZCMLDirectives | 11:14 |
| flox | factly, i already seen this page.... | 11:15 |
| flox | but i missed the point on *class/factory* | 11:16 |
| flox | now it is ok... :) | 11:16 |
| philiKON | :) | 11:16 |
| flox | thank | 11:17 |
| flox | it works! | 11:17 |
| flox | i am in charge to evaluate the benefit to switch from to Zope3 for our Zope/Plone project | 11:19 |
| philiKON | if it uses a lot of plone technology, it might make more sense to use zope3 technology in zope 2 via five | 11:20 |
| flox | no... factly we changed completely the Plone skin... we do not use it. | 11:20 |
| *** volvox has joined #zope3-dev | 11:21 | |
| flox | we started with Plone bec we were newbies, and it looks easier, at the beginning | 11:21 |
| flox | and the features or Plone, we do not use a lot | 11:21 |
| flox | we have to clean-up everything and re-engineer large parts of the site | 11:22 |
| flox | this is the reason, i try to push to adopt Zope3.... | 11:23 |
| flox | but i lack some arguments | 11:23 |
| philiKON | well, why reengineer if it already works? | 11:23 |
| flox | it is low-performance | 11:24 |
| philiKON | there's your argument :) | 11:24 |
| philiKON | of course, plone can be made fast... | 11:24 |
| flox | in ur book u tell that catalog and indexing are "still in development" | 11:25 |
| flox | i guess that today it works ok, no? | 11:25 |
| philiKON | yup | 11:29 |

| adamSummers | but I get the following error when viewing the page: File "/Users/adam/z3-dev/Zope3/src/zope/publisher/http.py", line 851, in _implicitResult | 12:56 |

| *** mgedmin has joined #zope3-dev | 12:57 | |
| philiKON | hmmm. that's weird | 12:57 |
| adamSummers | No mate- I wouldn't dream of it :) | 12:57 |
| philiKON | i wonder if that's mandated by some spec | 12:58 |
| philiKON | i would file a bug | 12:58 |
| mgedmin | but is it a bug? | 13:00 |
| * mgedmin reads logs | 13:00 | |
| mgedmin | if a view's __call__ returns a unicode string | 13:00 |
| *** faassen has joined #zope3-dev | 13:00 | |
| *** mkerrin has joined #zope3-dev | 13:00 | |
| mgedmin | the zope publisher encodes that string into some charset (well, it's always UTF-8, but it could be some other) | 13:01 |
| mgedmin | and changes the Content-Type header to mention that charset | 13:01 |
| mgedmin | now the charset="..." parameter is only defined for text/* MIME types | 13:01 |
| philiKON | true | 13:01 |
| philiKON | so, there's the spec :) | 13:01 |
| mgedmin | adamSummers: I'd fix that in a view class: | 13:01 |
| mgedmin | class MyView(BrowserView): | 13:01 |
| mgedmin | template = ViewPageTemplateFile('whatever.pt') | 13:01 |
| mgedmin | def __call__(self): | 13:02 |
| mgedmin | self.request.response.setHeader('Content-Type', 'whateveritwas') | 13:02 |
| mgedmin | return self.template().encode('UTF-8') | 13:02 |
| philiKON | self.request.response.setHeader('Content-Type', 'whateveritwas; charset=UTF-8') | 13:02 |
| philiKON | and i'd use BrowserPage as a base class :) | 13:02 |

| mgedmin | volvox: you might want to specify a more human-readable name to the @action decorator | 14:44 |
| mgedmin | it uses the hex-encoded label by default (when the label contains certain unsafe characters) | 14:45 |
| volvox | oh well, the label is 7-bit ascii | 14:45 |
| volvox | i'm not diving inside "Wrong contained type"... message errors are a bit obscure sometimes, but I can handle it | 14:46 |

| * mgedmin wants a frozendict | 17:04 | |
| * benji wants a pony | 17:09 | |
| baldtrol | hah! | 17:09 |
| rocky | hmm... how do you all feel about a new zcml directive that creates an actual new view component (and even creates the new class for that component) but doesn't need an existing class to exist? is it evil? i guess this is sort of what <browser:page> does | 17:13 |
| mgedmin | yup, evil | 17:15 |
| benji | rocky: I'd suspect most would consider that evil | 17:15 |
| baldtrol | not that i'm a core dev guy at all, but i'm -1 on zcml doing more than it does already :\ | 17:15 |
| * mgedmin sometimes wishes for user-defined zcml macros | 17:16 | |
| * mgedmin is sometimes evil, too | 17:16 | |
| rocky | any of you familiar with the zope 2 CMFFormController product ? | 17:16 |
| * Theuni wants a frozenpony | 17:18 | |
| ignas | rocky: evil, as it does not save that much effort, but greatly increases the effort required for extending the view in any way | 17:18 |
| rocky | ignas: well, the particular idea i have would be *greatly* simplified if it were all done via zcml | 17:19 |
| rocky | basically i want to define the page flow in ZCML which would create a view component that follows that page flow | 17:20 |
| faassen | rocky: it's currently not allowed to extend ZCML for anything :) | 17:20 |
| rocky | lol | 17:20 |
| ignas | which would basically become a tool for doing that specific task, in a general purpose framework | 17:20 |
| faassen | rocky: you're supposed to type a lot of ZCML | 17:20 |
| *** whit has joined #zope3-dev | 17:20 | |
| rocky | faassen: have you used CMFFormControler before? | 17:20 |
| faassen | rocky: no, I saw a presentation on it once long ago. | 17:21 |
| rocky | basically i'd like to define page flow: if page 1 is submitted by action 1, it goes to page 2, if its submitted by action 2, it goes to page 3 ... when action 8 is submitted on page 3, it performs some validation and then goes to page 6 | 17:21 |
| rocky | etc etc | 17:21 |
| rocky | with CMFFC, that kind of logic is defined by .metadata files | 17:21 |
| rocky | i'd like to do a similar concept but defined by ZCML | 17:22 |
| benji | rocky, I don't hold "custom" ZCML up to the same standard as core ZCML though, if you define ZCML for your project and it helps you, feel free | 17:22 |
| *** vlado_ has joined #zope3-dev | 17:22 | |
| rocky | benji: well, what i'm brainstorming about i'd love to contribute back to zope 3 core as an extension to formlib or as a new "zope.pageflow" type project | 17:22 |
| * rocky wishes people weren't so anti-zcml these days ... | 17:23 | |
| faassen | rocky: if you want it to fly at all in the current Zope 3 consensus thing.. | 17:23 |
| faassen | rocky: you define it in terms of existing ZCML thingers. | 17:23 |
| rocky | faassen: nothing to compare it to ;) | 17:23 |
| faassen | rocky: and you have a few handy factory functions that you call from your ZCML | 17:23 |
| rocky | well... perhaps describing it like how you do zope.wfmc stuff | 17:23 |
| faassen | rocky: the zope.annotation package has an example of a handy factory thing. | 17:23 |
| faassen | rocky: formlib of course does a lot in Python and then hooks it up using ZCML | 17:24 |
| benji | if you really think the ZCML makes a major contribution (opposed to using Python), try it; if it's compelling it might get into the core | 17:24 |
| faassen | rocky: I don't know whether your usecase could work that way. I don't even know whether I agree with the consensus on ZCML. | 17:24 |
| *** vlado has quit IRC | 17:24 | |
| faassen | rocky: but I also don't disagree with the consensus, so I'm just waiting until I got a better idea. :) | 17:25 |
| rocky | well, all i'm really talking about is basically autogenerating formlib based views with appropriate actions so that i can model page flow in zcml and touch little code (of course you'd still need to write code if you want custom stuff to happen during an action) | 17:25 |
| faassen | autogenerate formlib based views, huh? :) | 17:26 |
| faassen | I mean, I can tell you one thing, editform was evil. | 17:26 |
| ignas | rocky: ZCML being something like a small Domain Specific Language that can be extended "easily" i am weary of adding new keywords to it unless they are of a general purpose (having an extension, like another namespace etc. is fine though) | 17:26 |
| * mgedmin is pushing for a purely functional zcml | 17:27 | |
| *** BjornT has quit IRC | 17:27 | |
| mgedmin | or should I say declarative? | 17:27 |
| faassen | mgedmin: how is ZCML not purely declarative now? | 17:27 |
| rocky | i can see the only way i could properly get feedback is if i were to demonstrate a use case being fulfilled ;) | 17:27 |
| mgedmin | well, I want it to be order independent | 17:28 |
| faassen | that'd be nice. | 17:28 |
| mgedmin | and unloadable at run time | 17:28 |
| faassen | I'm interested in experimenting with a way to make ZCML go away/autogenerate ZCML, something. | 17:29 |
| mgedmin | with an internal notation that is not a list of tuples that contain references to unpickleable closures constructed by the parser | 17:29 |
| benji | plus, if ZCML were "unloadable" the test layers could then be torn down, making the tests faster | 17:29 |
| faassen | I mean, ZCML should be there when needed but not when not needed. As to ZCML being a more declarative language I'd be happy, I pushed for that in the past. | 17:30 |
| faassen | when TALES expressions were sneaking in and such. :) | 17:30 |

| rocky | faassen: the biggest problem with the whole "be there when needed but not when not needed" is that most people have no idea when its needed or not needed ;) | 17:38 |
| rocky | so many people don't understand that keeping configuration out of python has huge advantages when bringing in non-python people | 17:39 |
| benji | rocky, I percieve some of that as is a tension between the we-write-deploy-and-maintain-it people and the we-write-it-and-throw-it-over-the-wall people | 17:41 |
| baldtrol | rocky: not to jump in, but the glut of zcml directives provides another hurdle to jump when bringing in non-python people. i've been playing with zope3 for almost a year, and i still learn new things about zcml once in a while. | 17:41 |
| *** hdima has quit IRC | 17:41 | |
| baldtrol | unless zope3 is the only framework you use and develop for and in, it's just "another thing to remember and forget" | 17:41 |
| rocky | baldtrol: the logic has to be implemented somewhere, whether its in xml or in python code, its still "another thing to remember and forget" | 17:43 |
| rocky | but regardless, too much xml is a bad thing too | 17:43 |
| rocky | i'm not saying zcml is perfect | 17:43 |
| rocky | i just think there's a healthy compromise | 17:43 |
| rocky | j2ee has waaaaaay too much crap in xml | 17:43 |
| Theuni | baldtrol: i'm "using" zope 3 since it began, and i'm learning news things everyday :) | 17:46 |
| baldtrol | ;) | 17:51 |
| baldtrol | sorry, didn't mean to dip on the conversation... we found a baby snake in the office, had to escort it outside | 17:52 |
| Theuni | lol | 17:52 |
| benji | strangely enough, baldtrol, I've had the same experience, but with a baby bird :) | 17:53 |
| baldtrol | rocky: i think zcml is great, i'm not picking on it directly. i just know that i use rails, a little pylons, turbogears, and a lot of zope3... things in markup that are obvious (browser:page, mailer: etc) should be there... | 17:53 |
| baldtrol | but too much configuration that's not in the language i'm using, or using an xmlns i'm not familiar with, just makes for something that impedes, rather than accelerates, development times :\ | 17:54 |
| *** admp has joined #zope3-dev | 17:54 | |
| baldtrol | benji: hee... a little snake i can see sneaking in... how did a baby bird wander in? :) | 17:54 |
| rocky | baldtrol: right, i think thats pretty much how i feel | 17:55 |
| rocky | but for me, i see modeling workflow as something better suited to XML than python | 17:55 |
| faassen | I'm not discounting explicit configuration. | 17:55 |
| faassen | or domain specific languages. | 17:55 |
| faassen | I'm just wondering whether we have a more graceful path. | 17:55 |
| faassen | from just 1 file apps to multi file explicit configuration apps. | 17:56 |
| faassen | let alone multi file explicit configuration you've got tests for everything under the sun apps. | 17:56 |
| baldtrol | rocky: i agree... have you looked at the xml design for workflow in srichter's workflow package? it's a good one, and is set up as an element of the workflow, not zcml config. admittedly, that may be picking nits at that point, but the UI dumps and reads in the xml on it's own, should you want to do it that way | 17:56 |
| faassen | and I wonder whether we can't get mor agility into it all. | 17:56 |

| mgedmin | Field inherits Attribute, but IField does not inherit IAttribute | 19:00 |
| mgedmin | is that correct? | 19:00 |
| mgedmin | I mean, intentional? | 19:00 |
| * mgedmin just discovered that adding an attribute named 'interface' to a custom field is not a good idea | 19:01 | |
| srichter | not intentional | 19:02 |
| srichter | you can safely add this | 19:02 |
| srichter | since attribute requires there to be a name, which certainly IField also requires | 19:03 |

| flox | i try to send back a 'application/xml' document fom a PT | 22:05 |
| flox | but an error occurs bec of "ValueError: Unicode results must have a text content type." | 22:05 |
| baldtrol | flox: if it's really just an encoding issue, you can str() your results, or .encode("latin1") or something similar | 22:07 |
| flox | my tag is: <tal:if condition="validReceipt" replace="structure context/example.xml/data" /> | 22:08 |
| mgedmin | flox: http://zope3.pov.lt/irclogs/%23zope3-dev.2006-06-20.log.html#t2006-06-20T13:00:44 | 22:08 |
| flox | i should use python inside the TALES expression? | 22:08 |
| flox | the XML is plain ASCII | 22:08 |
| mgedmin | flox: ignore the tales expression; read the irc log excertp I linked | 22:08 |
| mgedmin | it contains the answer to your question | 22:09 |

| mgedmin | file a bug? | 22:13 |
| flox | mgedmin: but i will implement ur example, i think | 22:13 |
| flox | mgedmin: this is a bug, you think | 22:13 |
| mgedmin | maybe | 22:15 |
| mgedmin | well, yes | 22:15 |
| mgedmin | you should not be able to cause a SystemError by entering values in web forms, IMO | 22:15 |
| mgedmin | I take that back | 22:15 |
| mgedmin | syntax errors in page templates cause System error messages too | 22:16 |
| mgedmin | nevertheless it is at the very least confusing to the users, as you've demonstrated | 22:16 |
| flox | i try to change the Charset inside the header... but useless: | 22:18 |
| flox | <span tal:define="dummy python:request.response.setHeader('Content-Type', 'application/xml;; charset=UTF-8');" /> | 22:18 |
| flox | j'ai la même erreur à la sortie | 22:19 |
| mgedmin | I think you cannot work around this restriction | 22:19 |
| flox | ok | 22:20 |
| flox | so i will add some piece of python code to work around this | 22:20 |
| flox | taking ur example from earlier today | 22:20 |
