Re: [Pharo-users] Rest Services with pharo objects as parameters

by Esteban Lorenzano

Hi, if this is from voyage, then is a complicated query, because it is storing a reference to a second root. Letâs say you have an object a1 who is an instance of A and an object b1 who is an instance of B. b := B new. a := A new data1: 42; data2: âsomethingâ; refB: b. which means what you want, in plain Pharo would be something like this: aCollectionOfA select: [ :each | each refB = b ]. but since you want to use Voyage, I guess you want to execute the query *in mongo* (to avoid loading all instances of A into memory). So, in voyage you need to do it in some hack way: B selectOne: [ :each | â¦ ]. A selectMany: [ :each | (each at: ârefB.__idâ) = b voyageId ]. this will solve your problem, I guess. Esteban ps: this is hacky because what in general you do with this kind of structures is to keep a list of A in B, along with your list of B in A (that means, you define a many-to-many relationship) > On 22 Nov 2016, at 11:42, Asbath Sama biyalou via Pharo-users <pharo-users(a)lists.pharo.org> wrote: > > > From: Asbath Sama biyalou <asamabiyalou(a)yahoo.com> > Subject: Rest Services with pharo objects as parameters > Date: 22 November 2016 at 11:42:25 GMT+1 > To: Pharo users users <pharo-users(a)lists.pharo.org> > > > Hello Everybody. > > I have two classes ClassA(data1 data2 ref_ClassB) ClassB (data3 data4). > > I want to get list of classA where ref_ClassB = ClassB.

Rest Services with pharo objects as parameters

by Asbath Sama biyalou

Hello Everybody. I have two classes ClassA(data1 data2 ref_ClassB) ClassB (data3 data4). I want to get list of classA where ref_ClassB = ClassB. I don't know how to do my url in order to sent ClassB as a parameter of the service. I am using Pharo 4.0 with Voyage-Mongo.

PharoJS

by Brad Selfridge

Does anyone know what the state of PharoJS is? I am looking at working on a big node.js project and would like to see if I could use PharoJS to do a lot of the work. ----- Brad Selfridge -- View this message in context: http://forum.world.st/PharoJS-tp4924045.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Re: [Pharo-users] [UFFI] Dealing with Windows types

by Dimitris Chloupis

ah perfect , easy enough, thank you Sven , I learned a ton today. Definitely will keep in mind. I can have a mix of non Unicode and Unicode data, so its not a problem per se. For now I am focused on creating a RPC, which means I will pass strings that will be interpreted by C++ and translated to Unreal API calls. Additionally to that I will be passing byte data for regular data, player lives, game level, ammo, time left etc. A part of the shared memory could be Unicode for international text that will appear in game. My problem was that Windows uses Unicode everywhere and it also uses data types that are double in size for C++ just to accommodate Unicode. That creates incompatibilites for the memory model I am creating that I want to be the same across Windows, Linux and MacOS. Basically the entire shared memory model will be one huge byte array shared between Pharo and C++ separated in 3 sections: Section 1- Header - this is where global data / general information is stored [standard size] Section 2- Commands - strings and data to be interpreted by C++ as Unreal API commands , 1 command at a time [standard size] Section 3- Live data- this is data to be stored with the game and describe the live state of the game itself so the player can carry on from where it exited the game without any need to save.

Definitely bookmarked for future reference. Thanks You might as well use the real thing (and then you're good for the future too): ZnUTF16Encoder new encodeString: 'ÎÎ»Î»Î¬Î´Î±'. "#[3 149 3 187 3 187 3 172 3 180 3 177]" ZnUTF16Encoder new encodeString: 'Greece'. "#[0 71 0 114 0 101 0 101 0 99 0 101]" ZnUTF16Encoder new decodeBytes: #[3 149 3 187 3 187 3 172 3 180 3 177]. "'ÎÎ»Î»Î¬Î´Î±'" ZnUTF16Encoder new decodeBytes: #[0 71 0 114 0 101 0 101 0 99 0 101]. "'Greece'" Good luck with your coding. Sven
