Gin "wildcard route conflicts with existing children"

router.GET("/:something/", Blabla)
router.GET("/:something/else", Bleble)
router.GET("/:something/:different/:again", Blibli)

panic: wildcard route ':different' conflicts with existing children in path '/:something/:different/:again'

Am I doing something wrong or is this simply not allowed?

https://github.com/gin-gonic/gin/issues/1301 , so it's not allowed

Wow, that is terrible.

Comment From: thinkerou

expected, thanks! you should re-write your route.

Comment From: wodim

Saying it's "expected" makes it double terrible, because it means you will never get around to fix it.

There is no way Gin should confuse Bleble with Blibli: Bleble has two slashes, and Blibli has three!

In the end I had to write my own router like this:

router.GET("/", ViewHome)
router.GET("/:first", ViewRouterOne)
router.GET("/:first/:second", ViewRouterTwo)
router.GET("/:first/:second/:third", ViewRouterThree)
router.GET("/:first/:second/:third/:fourth", ViewRouterFour)

Then from those functions you can redirect requests to the correct view functions. I hope this is useful to someone.

how this routes cause conflict

pGroup.POST("/fork", controllers.Fork)
pGroup.POST("/:id/process", controllers.processN)

Comment From: appcypher

Wow! Gin routing pattern matching is a mess. Now I have to refactor my app to use another framework.
