Thor::Error: Could not find "config/database.yml"

Describe the bug This occurs immediately after running the template.

I am running a rails 7.2 application.

It fails to find my database.yml file.

It exists as expected here.

It added 2 gems to my Gemfile

  LOCATION=https://raw.githubusercontent.com/fractaledmind/enlitenment/main/template.rb?token=****

├── config
    ├── application.rb
    ├── database.yml
    ├── puma.rb
    └── routes.rb

Expected behavior

N/A

I meant try this:

full_path = in_root { find_in_source_paths("config/database.yml") }
database_yaml = DatabaseYAML.new full_path

[thedumbtechguy]

It didn't work.

The source paths do not include the application root as listed here

[fractaledmind]

Try simply adding readme "config/database.yml" to the script and see if that errors

[fractaledmind]

And ?

in_root { readme "config/database.yml" } 

Ps. Thanks a ton for experimenting for me

[thedumbtechguy]

Same error

[thedumbtechguy]

Are you suspecting that the rails treats the app root as a source directory for templates? Does it do that on fresh install maybe?

[fractaledmind]

Can you add puts destination_root into the template and tell me what (if it executes) it outputs. We might need full_path = File.expand_path(path, destination_root)

[fractaledmind]

I am hopeful that this new commit will fix the issue. Can you give the new template a try: https://github.com/fractaledmind/enlitenment/commit/024e262931982f00979b7570722068bb1fc40ce1

[thedumbtechguy]

destination_root outputs the correct path.

[thedumbtechguy]

Confirmed that the change to destination_root fixes the problem

[fractaledmind]

Perfect.
