Not compatible with ruby 3.0

[rubydev]

After upgrade Ruby to version 3.0.1 code is crashing:

config.before(:suite) do
  DatabaseCleaner[:mongoid].strategy = :deletion, { except: %w[roles exchange_rates] }
end

An error occurred in a `before(:suite)` hook.
Failure/Error: DatabaseCleaner[:mongoid].strategy = :deletion, { except: %w[roles exchange_rates] }

ArgumentError:
  wrong number of arguments (given 1, expected 0)

It looks, that it is related with DatabaseCleaner/database_cleaner#677

@rubydev Yes, that syntax no longer works in Ruby 3.0... you'll need to pass an array instead:

config.before(:suite) do
   DatabaseCleaner[:mongoid].strategy = [:deletion, except: %w[roles exchange_rates]]
end

I've updated the README to that syntax, while I was at it. I wonder if its possible to do a deprecation warning in < Ruby 3.0, and a more helpful error message in >= Ruby 3.0?

@botandrose Hello, thank you! But after change to array, result is same:

An error occurred in a `before(:suite)` hook.
Failure/Error: DatabaseCleaner[:mongoid].strategy = [:deletion, except: %w[roles exchange_rates]]

ArgumentError:
  wrong number of arguments (given 1, expected 0)

# ./spec/rails_helper.rb:32:in `block (2 levels) in <top (required)>'

Any idea why it doesn't work? Thank you!

same here, any solutions?

[tstaetter]

found a solution, works for me:

# inside rails_helper.rb
RSpec.configure do |config|
...
  # Clean DB after testing
  config.before :each do
    strategy = DatabaseCleaner::Mongoid::Deletion.new except: %w[<your collection names here>]
    DatabaseCleaner[:mongoid].instance_variable_set :'@strategy', strategy
    DatabaseCleaner[:mongoid].start
  end

  config.after do
    DatabaseCleaner[:mongoid].clean
  end
end

Thank you, that works for me too!
