[Pharo-users] complex json parsing.

[Roelof Wobben]

Hello, I try to make a  app which displays images from a external api . I was hoping I could do it with only 1 json parsing but to get the right size of images I need more then 1 Right now I have two classes with fromJson methods Painting class >> fromJSON: json     | instance |     instance := self new.     instance         title: (json at: #title);         painter: (json at: #principalOrFirstMaker);         imageUrl: ((json at: #webImage) at: #url).     ^ instance Paintings class > fromJSON: json fromJSON: json     | instance artObjects |     instance := self new.     artObjects := json at: #artObjects.     artObjects         do:             [ :eachArtObject | instance addPainting: (Painting fromJSON: eachArtObject) ].     ^ instance but to get it working right , I have to do it like this : Painting class >> fromJSON: json     | instance |     instance := self new.     instance         title: (json at: #objectNumber);    ^ instance but the problem is now I need a second call to this url :  https://www.rijksmuseum.nl/api/nl/collection/<<objectNumber>/tiles?key=[API_KEY]&format=json and then need a new imageUrl out of it. and then have one object with objectNumber and the new url Also I have to make a call to this url : https://www.rijksmuseum.nl/api/nl/collection/<<<objectNumber>>?key=[API_KEY]&format=json and also get some data out of it so that a painting will be one object with the objectNumber, new imageurl and some data out of the last call Do I need to make some more object to get this working or is there a way I can change the code I use now to get things working Regards, Roelof
