There was a problem hiding this comment.
Unless you need to access Rails’ view helpers, another way to render to HTML is to call it. html = component.call I’m not sure how Turbo handles controller-less rendering when you pass a renderable: (see above) but I wonder if looking into this might reveal a cleaner way to get a rendering context without a controller.

@andrewjanssen thanks for the PR. I left a couple of comments. I’m going to do a little research to see if there’s any way we can improve on this. Totally agree we need to cover it in the docs. |

You're welcome! Yes, it would be nice to avoid this fake object approach. Hard for me to know if this complexity could be pushed into phlex-rails or if that would be detrimental. |

I want to migrate an existing project to Phlex. But when moving my AR-callback-driven Turbo Stream renders, I hit exceptions and confusement. This PR will help others avoid the investigation that I did to learn how to render from AR callbacks, background jobs, etc.
