Re: [Pharo-users] Date offset in Glorp and RDBMS

by Sven Van Caekenberghe

Hi Tomaz, Consider DateAndTime now asUTC asDate = Date today. which is false (on most systems), while DateAndTime now asUTC asDate equals: Date today. is true. #equals was added specifically for that purpose (ignore the offset). Note also that an abstract date (year/month/day) does not exist without the context of a proper timezone (an offset is not enough).

Date offset in Glorp and RDBMS

by eftomi

Dear all, Going through the remaining red tests in PharoADO + Glorp, I have a sort of a conceptual challenge. Some of the Glorp tests are checking the equality of dates written to and then returned from the database. Pharo regards the dates as not equal if their time offsets are different despite the fact that the date (in a narrow sense) is the same. For instance: "2019-12-29T00:00:00+01:00" is not equal to "2019-12-29T00:00:00+00:00" The challenge is that the ActiveX Data Objects (ADO) library that I'm using returnes the dates in Variants which don't have any information about the offset. The conversion from ADO variants to Pharo's Date is done in PharoCOM package. What would be the best approach to somehow ignore the missing offset or impute a proper value? Of course it's better to ignore a missing data than to impute a wrong value. How is this handled with other DB systems?

Hei Pablo and thanks for an interesting project. I liked the feature that you can write code as actually code ð -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

It's difficult to give good design advice with such a partial picture of the domain, but two straightforward solutions might be: 1. self isDeploymentMode ifTrue: [ "change data" ] 2. or, self sanitizationStrategy: (NoSanitization | ProductionSanitization) ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Users-f1310670.html

Re: [Pharo-users] can I write this without the three if then;s

by Dennis Schetinin

It would be an overkill to do it for this particular case, but Smalltalk makes it possible to implement a case-like construction: [ expression ] when: [ :value | condition1 ] do: [-0do :value | ... ]; when: [ :value | condition2 ] do: [ :value | ... ]; otherwiseDo: [ :value | ... ]; evaluate I am sure, something like this has been implemented already somewhere (maybe in Squeak?). Still not sure it is practical as compared to simple if-s, and for sure not widely used :) ...On the other hand, sometimes the case-like construction can be considered a more intension-revealing style.
