| GaryPoster | hi y'all. Two related questions about datetimeutils. I needed something to localize a naive datetime.datetime (i.e., add a timezone) on the basis of system time. I decided to harden them using the approach in datetimeutils, so I leveraged some protected (_*) methods in datetimeutils and got something that does the job in five or six lines. My questions: does something like this exist already? If not, anyone mind if I check it into | 03:08 |

| mgedmin | I have a question about menus and i18n | 16:37 |
| mgedmin | are menu titles i18n message IDs? | 16:37 |
| mgedmin | if so, do I need to explicitly say i18n:translate="" when I use tal:content="menuitem/title"? | 16:38 |
| mgedmin | the rotterdam skin does so, and I'm not sure why | 16:38 |
| srichter | I think they are message ids | 16:39 |
| dreamcatcher | mgedmin: i think the rotterdam skin may predate message ids *wink* | 16:39 |
| srichter | but just because you call menitem/title does not mean they get translated | 16:39 |
| srichter | i18n:translate="" tells the title to be translated | 16:39 |
| mgedmin | ah | 16:40 |
| mgedmin | I recall a discussion on zope3-dev about automatic translation of message IDs when they are included in page templates | 16:40 |
| mgedmin | at the time message IDs got translated even without i18n:translate="" | 16:41 |
| mgedmin | was that changed? | 16:41 |
| srichter | no, we never had this functionality | 16:41 |
| * mgedmin blinks | 16:42 | |
| srichter | it was proposed to do that | 16:42 |
| mgedmin | I'll believe you ;-) | 16:42 |
| srichter | but Jim vetoed this proposal | 16:42 |
| J1m | explicit is better than implicit | 16:42 |
| J1m | actually, I didn't veto the proposal | 16:43 |
| J1m | because there never was a proposal | 16:43 |
| J1m | When I sked for a proposal, the potential proposers ran out of steam | 16:43 |
| srichter | because they saw no hope to get it passed ;-) | 16:44 |
| J1m | When I asked for a proposal, the potential proposers ran out of steam | 16:44 |
| srichter | which is good, I totally agree with you | 16:44 |
| mgedmin | approach #12 from http://www.skirsch.com/humor/techarg.htm :-) | 16:45 |
| * mgedmin changes the topic | 16:46 | |
| J1m | I actually thought they were making some reasonable arguments | 16:46 |
| dreamcatcher | i dont quite agree. i think it's moving explicitness the wrong way. explicitness in code should have precedence over explicitness in display, but im not too strong on that :) | 16:46 |
| J1m | (I don't remember what they were) | 16:46 |
| *** apoirier has joined #zope3-dev | 16:46 | |
| mgedmin | if I get a 500 Internal Server Error in a functional doctest, what is the easiest way to get the traceback? | 16:46 |
| J1m | I had (and still have) an open mind on the topic. | 16:46 |
| J1m | ++skin++Debug | 16:46 |
| J1m | If that doesn't work, or is insufficuent, then pass handle_errors=False to http | 16:47 |
| J1m | Then you can do post-mortem debugging | 16:47 |
| mgedmin | thanks | 16:50 |

| *** regebro has joined #zope3-dev | 18:40 | |
| regebro | Hi all! I just ran into a (mainly stylistic) problem: In CMF, when you want a form to do something, like remove attendees from a calendar event, you write a little method on the object, or make a python script. | 18:41 |
| regebro | I guess in Zope3, you make a method on the view, and then configure that up as a page, right? And end the view with a redirect? | 18:42 |
| regebro | Is that the "Zope3ish" way? | 18:42 |
| *** bradb has quit IRC | 18:43 | |
| mgedmin | I think the usual Zope 3 idiom is to have an 'update' method in the view | 18:44 |
| *** bradb has joined #zope3-dev | 18:44 | |
| mgedmin | that checks for various submit buttons in self.request and performs required actions | 18:45 |
| mgedmin | usually you will include something like <tal:defs tal:define="dummy view/update" /> at the top of the page template | 18:45 |
| mgedmin | and define a self-posting form inside | 18:45 |
| *** Aiste has joined #zope3-dev | 18:46 | |
| regebro | Ah, OK. Yeah, that gives a nice flexibility in how to build the forms. | 18:46 |
| SteveA | mgedmin: I'd really like to get this dummy tal statement removed from page templates | 18:46 |
| *** vlado has quit IRC | 18:46 | |
| SteveA | mgedmin: and have the zcml page directive to have a pre-render attribute to say what attribute on the page's view's class is called | 18:47 |
| SteveA | mgedmin: before the page is rendered | 18:47 |
| regebro | Yeah, that would be a bit neater. | 18:48 |
| regebro | OK, so I'll do the dummy thing, and I'm easily forward-updateable if we get the pre-render attribute. ;) | 18:48 |
| regebro | Thanks. | 18:49 |
| J1m | SteveA, I hope to propose something along those lines soon | 19:12 |

| SteveA|out | J1m: I know that we talked about this a while ago. I originall proposed a magic attribute. You counter-proposed an explicit zcml attribute. I agreed, and said something about doing a proposal. | 19:21 |

| J1m | And Gary has done some interesting things along these lines. | 19:23 |
| J1m | Which I need to review | 19:23 |
| SteveA | forms isn't the only use-case for the pre-render attribute in zcml, but it is the main one. | 19:24 |
| J1m | yup | 19:30 |
| SteveA | so, are you still keen on a pre-render attribute, or will formcontroller-like stuff make a pre-render attribute unnecessary ? | 19:32 |
| J1m | I don't know the details at the moment. :) | 19:33 |
| J1m | I'm keen on a silution to the problem soon. | 19:33 |

| __gotcha | is it correct that views have been replaced by multiadapters ? | 19:45 |
| __gotcha | or a wrong supposition ? | 19:45 |
| SteveA | views are implemented using multiadapters | 19:45 |
| SteveA | there's still the notion of presentation components | 19:46 |
| SteveA | and a view is a kind of presentation component | 19:46 |
| __gotcha | ok | 19:46 |
| __gotcha | thanks | 19:46 |
| SteveA | but at the implementation level, they're all adapters | 19:46 |
| __gotcha | iam I correct if I think that vew being adapters is recent | 19:47 |
| __gotcha | iam I correct if I think that views being adapters is recent | 19:47 |

| __gotcha | ok | 19:47 |
