wildcard route ':id' conflicts with existing children in path

[tochka]

I have the following routers, but when I run the program I see the next error

r.POST("/user/actions/search", s)
r.POST("/user/:id/collections/relations", addR)
r.DELETE("/user/:id/collections/relations", removeR)
r.GET("/user/:id", g)
r.POST("/user", a)
r.DELETE("/user/:id",d)

panic: wildcard route ':id' conflicts with existing children in path '/user/:id/collections/relations'

See julienschmidt#175 (comment)

Maybe user_id or user_token in url query string or form data is a better practice.

r.POST("/user/actions/search", s)
r.POST("/user/collections/relations", addR)
r.DELETE("/user/collections/relations", removeR)
r.GET("/user", g)
r.POST("/user", a)
r.DELETE("/user",d)

http "localhost:80/user/actions/search?user_id=137118"

PS. thanks for your reply~ @erikdubbelboer
