When I was porting my site to Phoenix a while back one of the things that I got hung up on was porting the RSS route, which was previously “tag.rss”. With the period there I couldn’t figure out how to get it working and ended up just going with :name/rss in the short term.
Any suggestions for how to make this work?
There’s a plug just for this situation!
Thanks! Very vague on the usage details but hopefully simple enough to just dig into the code.
Lifted from the readme:
# If you are using phoenix:
# Add the plug to your endpoint.ex file:
defmodule MyProject.Endpoint do
plug TrailingFormatPlug # add this
That’s all there is to it
One detail that took some trial and error on my part to find was that you should not specify the
.format route separately. That led to a rabbit hole of confusion about not allowed characters due to trying to map
I.e. you do need to adjust your
plug :accepts list accordingly for the pipeline (add extension, in my case
Speaking of which, it would be cool if you could specify
accepts for individual routes rather than just an entire pipeline.
This is the point of pipelines You could create a scope for the routes needing specific content negotiation and then
Yeah, I get that. It’s just kind of cumbersome when you are dealing with a single action on a
resources derived route. Particularly when it’s a nested resource.
In my case, I just want to add a
text/calendar representation to
:show action for a resource.
Just my opinion, but it sounds like that is a scenario that’s more the exception than the rule, meaning it should be a cumbersome 1-off rather than something cumbersome that you’d be doing over and over.
Just raising it as something that has a bit more friction than I expect from Phoenix’s otherwise really excellent routing.
I’ve also encountered this when wanting to provide RSS representations for search results, etc. That was a bit easier though because the routes weren’t nested.
Having said that, I could see adding RSS for index actions in a number of places. Time will tell.
