Quickly test a Rails routing table from IRB

David — Fri, 27 Mar 2026 21:02:17 UT

Here is a reminder of two quick ways to check your routes work, directly in IRB. Firstly, what path can you generate from your helpers?

irb(main):001:0> app.url_for [Client.last, :manage, Project.last]
  Client Load (2.0ms)  SELECT "clients".* FROM "clients" WHERE "clients"."deleted_at" IS NULL ORDER BY "clients"."id" DESC LIMIT $1  [["LIMIT", 1]]
  Project Load (2.0ms)  SELECT "media_stores".* FROM "media_stores" WHERE "media_stores"."type" = $1 AND "media_stores"."deleted_at" IS NULL ORDER BY "media_stores"."id" DESC LIMIT $2  [["type", "Project"], ["LIMIT", 1]]
=> "http://www.example.com/2-gelato-4-u/manage/projects/7"

What is the name of a class, in a class method?

# bad
class Foo
  def self.hello
    puts class_name # is a monkey patch from yard so probably won't work in production
    puts class.name # is 'Module'  :(
  end
end

Static sites with Racket

David — Sun, 26 Jan 2020 09:12:10 UT

I saw from a recent Reddit thread that there are several static site generators in Racket. They vary in the markup language that can be used for pages, and the extent to which individual pages can have programmatically generated custom content.

Interesting options include

racket darwin (a fork of the dormant frog project; not related to ‘darwin’, Apple’s open source Mach kernel for operating systems)
pollen (that was written to make web books such as Practical Typography)
racket stories
