Dependency Injection for serializers

[tvanderlois]

Looking at the code, it doesn't look like Taffy does dependency injection on serializers currently. 3.0.0 C2

I took some time to look at this yesterday evening and thought I had made some progress but although the dependency injection itself seemed to work, I started getting strange issues with things not being returned from the endpoint correctly - so strange that it must be something about my particular codebase.

What I did find:

In newRepresentation() https://github.com/atuttle/Taffy/blob/develop/core/api.cfc#L929 you are using the loaded beanFactory to create the serializer.

If you are using an external beanFactory, and you have your custom serializer loaded into the bean factory, and you provide just the name of the customSerializer, not the path to framework.serializer - everything should work at that point. Again, in mine I was getting strange issues, but they were so strange I can't believe it is a taffy issue, but I didnt have enough time to research it further.

Now, if you are not using an external bean factory, I don't believe the internal bean factory is loading anything but the resources directory: https://github.com/atuttle/Taffy/blob/develop/core/api.cfc#L320
That may be the issue with the example (https://github.com/atuttle/Taffy/tree/master/examples/api_jsonutil) not working.

So I started researching this again this morning and found the issue I was having, you need to ensure that your beanFactory is treating the serializer as transient, or it will cache withStatus() inputs from previous calls.

[atuttle]

Excellent point: Serializers should definitely be treated as transients. I do that with Taffy's built-in factory but we should document it for anyone using an external bean factory.

I have some changes in progress in the built-in factory to resolve dependencies of serializers as they're requested, but I still have 1 failing unit test that I need to resolve.

Leaving this open for now as a reminder to update the docs as discussed.
