Re: [Pharo-users] Voyage: Circular references

by Esteban Lorenzano

Hi Sabine, I'm trying to understand your problem. As far as I see, you have: - A set of Countries - A set of Trips Why Country is transient? When you declare an attribute as *transient*, that means its value will not be persisted, then when you retrieve it again, you will have country = nil in your trip (which I imagine is an error). How I would solve this problem? Well... both Trip and Country has to be persistent (both #isVoyageRoot should answer true). That should be enough... Now... you probably want your list of countries to be constant inside your app (since they are basically the same 150+others new each year-some no-more-there each year). This is like an enumeration (Country = #(Argentine France Germany ...) if this is your case, what you can do is to declare a different kind of accessor (in the same way you do it for magritte + seaside): something like this: Trip class>>#mongoCountry <mongoDescription> ^ VOMongoToOneDescription new attributeName: 'country'; accessor: (MAPluggableAccessor read: [ :trip | trip country name ] write: [ :trip :value | Country countryWithName: value ]); yourself this way you can keep in the database whatever value you want (an ISO, an internet extension, etc.) I hope this solve your problem :) Esteban On Jul 29, 2013, at 7:01 PM, Sabine KnÃ¶fel <sabine.knoefel(a)gmail.com> wrote: > Hi esteban, Thank you for answering.

OSProcess execution from specific directory

Hi! On execution of (PipeableOSProcess command: 'pwd') output , it always says root directory ("/"). Is it possible to execute command from specific directory? Or the only correct solution is like this?: (PipeableOSProcess command: 'cd /Users/jura/ ; pwd') output Thanks a lot. Cheers, Jura
