I’ll preface that I am very new to Elixir. I am trying to decode a paginated JSON response from my API but I am a bit lost on exactly how to implement the decoding. This is what the top-level JSON response looks like: _embedded: collection_currently: 0: {...} 1: {...} …

Ahh I just copied the output in my broswer. I promise it’s JSON though; I’m querying an API endpoint I created hahaha. Here’s the actual JSON response: { "_embedded": { "collection_currently": [ { "id": "5f4ff12189a6a3a49d61d7f2", "time": 1599074590, "summary": …

You can use the :as option to Poison.decode. That would be something along the lines of: Poison.decode( json_string, as: %{ "_embeded" => %{ "collection_currently" => [%CollectionCurrently{}] } } ) (Assuming that you have defined an appropriate Collection…

Ahh ok yeah I was using as: but I just wasn’t sure what the whole syntax would look like. This is what I have now: Poison.decode(body, as: %{ "_embedded" => %{ "currently_collection" => [%CurrentlyReprModule.CurrentlyBlock{}] }, "_links" => %CurrentlyRe…

The square bracket syntax in the :as option indicates a list (which makes sense, because that’s what square brackets are in Elixir.) So it makes sense to have them around %CurrentlyReprModule.CurrentlyBlock{}, because the "currently_collection" key is indeed supposed to have a list of those objects.…

Ok yeah that’s what I assumed. However, when I remove the brackets I get a Poison.EncoderError: unable to encode value: {"page", %ElixirServer.CurrentlyReprModule.Page{number: 0, size: 4, totalElements: 30, totalPages: 8}} Any idea why this is happening? The Page struct follows the same lines as m…

I’ve tried a very simplified version of it, which works: Poison.decode!(json_string, as: %{ "page" => %Page{} }) (With the Page module defined as you defined it above, and with json_string being the json string of your data.) This should work for you too. I suggest you proceed from there, and see…

You can use :jsn.as_map/1 ( jsn | Hex ) ~s( { "fields": { "summary": "Bug!", "issuetype": { "id": "10005" }, "project": { "key": "BUG" }, "description": { "type": "doc", "version"…

Your example looks like yaml, have you tried a yaml parser?
