Overriding scaffold erb templates

[craic]

Rails 7.0.2.3 ruby 3.0.0p0 ubuntu

I want to modify the erb templates used in scaffolding but the tailwindcss template engine doesn't pick up custom templates from lib/templates/erb/scaffold

Does it use a different location ? I don't see an option in 'rails g scaffold --help' where I can specify that explicitly

Thanks !

You can configure which files are watched in tailwind.config.js.

Please, can you double-check your answer? It sounds to me like it has nothing to do with the issue.

We are trying to override the erb templates generated by rails g scaffold [resource].
Usually, we put the erb files in locations like:

lib/templates/erb/scaffold/*.html.erb

Also, I have tried this path:

lib/generators/tailwindcss/scaffold/templates/*.html.erb

Both are not working.

Thanks @dhh

Ah I read it as a watching question. This gem is already overriding the scaffold templates, so that's probably why. Would be happy to look at a PR if you find a way to make this compatible with overwritten templates.

This source_root line here is overriding the default behaviour

tailwindcss-rails/lib/generators/tailwindcss/scaffold/scaffold_generator.rb

Lines 1 to 9 in 47f636b

	require 'rails/generators/erb/scaffold/scaffold_generator'
	require "rails/generators/resource_helpers"
	module Tailwindcss
	module Generators
	class ScaffoldGenerator < Erb::Generators::ScaffoldGenerator
	include Rails::Generators::ResourceHelpers
	source_root File.expand_path("../templates", __FILE__)

If I comment that out then I can pick up from
lib/templates/erb/scaffold/*.html.erb

Maybe an if / else clause that looks to see if the app has defined custom templates then use those, if not then use the ones in tailwindcss

Unfortunately I don't see how where the custom template path is defined in the regular generator.
If you can give me a pointer then I will try it out

@craic Not sure if this could be merged into the gem, but overriding the class method source_root did the trick.

I added this file lib/generators/tailwindcss/scaffold/scaffold_generator.rb

require 'rails/generators/erb/scaffold/scaffold_generator'
require "rails/generators/resource_helpers"

module Tailwindcss
  module Generators
    class ScaffoldGenerator < Erb::Generators::ScaffoldGenerator

      def self.source_root
        default_path = Rails.root.join("lib", "templates", "erb", "scaffold")
        return default_path if Dir.exists?(default_path)

        File.expand_path("../templates", __FILE__)
      end
    end
  end
end
