Setting collection data to an object

[chmchmchm]

Hiya, we're using GenericData.SetData in both this client and the javascript client. In the javascript client, the docs example allows for passing in an object with multiple properties to be serialized.

In this client I can't see a way to do that except setting multiple name/value pairs? Is there a way to pass in an object instead? If not, would you be able to add an overload for that?

Thanks very much!

In the Stream docs on collections here:

1. The javascript docs passing in an object with two properties
   

2. The C# docs calling SetData once for each property
   

3. What we'd be keen for

var collectionData = new GenericData();
collectionData.SetData(new Food("cheese burger", "4 stars"));
await client.Collections.Add("food", collectionData, "cheese-burger");

Hey @chmchmchm!

So it's important to know that the properties of collection entries are key-value pairs. new Food("cheese burger", "4 stars") is a good value, but it needs to have a key.

But you could do this already:

collectionData.SetData(foodId, new Food("cheese burger", "4 stars"));

Would that work for you?

I think if we did that the collection would have the structure

{
  "foodIdValue": {
    "name": "cheese burger",
    "rating": "4 stars"
  }
}

but we want this structure, without the extra level of nesting:

{
  "name": "cheese burger",
  "rating": "4 stars"
}

Is there any way to get that without calling SetData once for name and then again for rating?

Hey @chmchmchm,

The code snippet I have provided to you does exactly that.

var foodId = "foodIdValue";
collectionData.SetData(foodId, new Food("cheese burger", "4 stars"));

This will do that:

{
  "foodIdValue": {
    "name": "cheese burger",
    "rating": "4 stars"
  }
}

This already works today.

Hi @peterdeme,

Thanks for looking into this but I think we're misunderstanding each other - what you posted here:

That is the structure we don't want, from my message here:

What we would like is to not have foodIdValue, is that possible? To only have name and rating:

{
  "name": "cheese burger",
  "rating": "4 stars"
}

We'd like to be able to get that format by running just one command, passing the whole object, the same as you can do with the javascript client.

Hey @peterdeme - if that last reply isn't making sense, I'd be happy to set up a call to chat about it if that could be easier!

@chmchmchm it makes sense. Peter is back on Wed and we can probably provide an override

[peterdeme]

@chmchmchm hopefully this solves your problem: #68

edit: it is release now https://github.com/GetStream/stream-net/releases/tag/4.8.0

Hi, sorry for the slow reply.

I'm not sure that that does solve our problem, are you saying we should use the SetData<T>(string name, T data, JsonSerializer serializer) overload? Doesn't that still require a name property, where name would be a key to the rest of the data? We want just the object properties as the data themselves, with no other name.

Like this format:

{
  "1": "2",
  "3": "4"
}

How could we use that overload to get this format?

@chmchmchm

look at this one:

This is addressed by upgrading to v6 of the library, thanks very much everyone for the update 👍
