Reproduction steps

Add the following test case in Rails 8 and try to rename the variable password:

  def test_password_is_not_too_short
    password = "w" * (User::MIN_PASSWORD_LENGTH - 1)
    @user.password = password

    @user.password_confirmation = password
  end

Getting the error message The element can't be renamed.

Neovim

Same issue in neovim. But message is different though:

ruby-lsp --version: 0.23.6

Question

I am not sure if this is a bug. Maybe this is a limitation of Ruby-lsp. Please close the issue if this issue is scoped to be fixed as part of the roadmap or if it cannot be fixed.

Thank you for the report. This is not a bug, we just haven't implemented reference tracking for locals yet. I'll change the title and labels to make that clearer, since we don't have an issue for this created yet.

We can also update the docs: #3113
