Rails: rake task with arguments not working

Question

Here is my rake task

namespace :users do
  task :change_role, [:role] => :environment do |t, args|
    puts args.role
  end
end

I am calling it like this:

rake users:change_role["role"] but I am getting this error no matches found: users:change_role["role"]

Where are you putting this? There's nothing wrong with what you've written, or how you're invoking it. – Suasion

does your rake task file has file extension as .rake? – Superiority

@Superiority - my file is named users.rake – Gambrill

@meagar - it's in app/lib/tasks – Gambrill

Answer 1

You need to escape the square brackets when using them in some shells like zsh:

rake users:change_role\["role"\]

Defer

No it is not. That is the error from your shell telling you there are no matches for that command found. With zsh and no escaping the output is zsh: no matches found: users:change_role[ok]. Using zsh with escaping the output is ok – Defer

You're correct, its rake saying it can't find the command. In any case, you need to escape the brackets with zsh. – Defer

Ah, actually I think you're right. "No matches found:" is definitely not being output by rake; rake would have said "don't know how to build task...". – Suasion

That escaping isn't correct... I tried this rake users:change_roles[\"hello\"] and I am still getting the same error – Gambrill

Did you mean rake users:change_role[\"hello\"]? – Defer

Great call! the full error is indeed: zsh: no matches found: – Cannery

Answer 2

Put the rake task in single quotes.

rake 'users:change_role["role"]'

The only thing that works for me (Rails 5.0.7.2)!! – Obeisance

This is a zsh prereq. – Mithraism

we should ask the OP if he is using zhs or not. But this helped me, as I just switched to zhs. – Vladi

Answer 3

You can add unsetopt nomatch to your .zshrc file, as Chad Pytel describes in here

You the man, dog. This is the right answer for most people, especially those that are coming from bash. – Underdrawers

Answer 4

@infused way works, but if you want change to be permanent, so you can simply call rake users:change_roles["hello"], add following to your .zshrc:

alias rake='noglob rake'

this is working fine with me on Ubuntu 20.4, thank you – Greaves
