Re: ReStore and storing mixed dictionaries

by John Aspinall

Hi Offray, Youâre correct that ReStore canât store that kind of mixed dictionary directly. You could store the entire STON text as one string and reify it on read, though that would mean you canât easily query on the metadata. A compromise solution would be to define objects and slots for the key data youâd need to query on and a STON string for the residue. This could be a better solution anyway as excessive/complex Dictionaries can be a sign that you need to define a new class/classes. For your particular project this would depend on how similar the metadata is between tweets - if thereâs not much commonality then a Dictionary approach may be more appropriate.

Hi, Thanks, I will open a Ticket with the provider. All in all, I am not that happy with Empathyâ¦ maybe we should start looking for an alternative hosting provider for the mailing lists.

ReStore and storing mixed dictionaries

by Offray Vladimir Luna CÃ¡rdenas

Hi all, First of all, despite of being on a non-directly related matter with my question, congrats of Pharo 10. We (as now we have 2 active Smalltalkers in my country... Yay!) are creating a civic tech project with Pharo/Lepiter and we would like to store some Tweet metadata coming from Nitter[1]. As we're dealing with the differences between the official Twitter API and the unofficial Nitter one, we put the metadata we need in a dictionary that has several kinds of objects, from ordered collections to other dictionaries. [1] https://nitter.net/about Currently if we serialize a Tweet object in STON, we get this: Tweet { #created : 'Tue, 05 Apr 2022 12:37:56 GMT', #text : ' [ANN] Pharo 10 Released: pharo.org/news/pharo10-releaâ¦ <https://pharo.org/news/pharo10-released> \n', #id : '1511322244353597443', #user : NitterUser { #userName : 'pharoproject', #profileImageUrl : URL [ 'http://nitter.42l.fr/pic/pbs.twimg.com/profile_images/541743734/icone-pharo…' ] }, #metadata : { 'queries' : OrderedCollection [ { 'date' : DateAndTime [ '2022-04-05T13:36:58.546011-05:00' ], 'parameters' : 'https://nitter.42l.fr/pharoproject' } ], 'timelines' : { 'pharoproject' : '1511048498703126529' } } } As you can see, the metadata slot contains a dictionary with mixed classes of objects. But I read in the ReStore manual[2] (pg 14): """ Like other collections, the class of elements for both key and value can be any other persistent class, and will be the same for all elements of that collection (except in the case of inheritance). """ So, is ReStore unable to store metadata dictionaries like the one described in the previous STON code? if this is possible, how can I define it in the Tweet class>>reStoreDefinition? For the moment, I'm going to create a explicit "timelines" slot to store what was being stored at the #timelines key of the metadata dictionary. But, as metadata increases, instead of moving variables previously inside of a dictionary as explicit slots of an object, I think that having a explicit way of storing dictionaries with different kinds of objects, in contrast with only uniform ones, would be needed (but I don't know if this is in the design scope of ReStore). BTW, Lepiter has allow us to build a pretty fluent interface to browser Twitter/Nitter profiles and messages. Here it is how such UI looks for browsing last @pharoproject tweets: https://i.imgur.com/bxFze1g.png Any help on how to use ReStore in storing mixed dictionaries is appreciated. Thanks, Offray
