Question

I have a custom Module on my Rails project, and I want it to be a before_filter, is there
a way I can do?

before_filter TokenGenerator::Generator.generate_token("mytoken")

Answer 1

You can use a block as a before_filter:

before_filter do |controller|
    TokenGenerator::Generator.generate_token("mytoken")
end

Or you could create a separate class:

class TokenFilter
    def self.filter(controller)
        TokenGenerator::Generator.generate_token("mytoken")
    end
end

#...

before_filter TokenFilter

Or the usual method:

before_filter :token_generator

#...

private

def token_generator
    TokenGenerator::Generator.generate_token("mytoken")
end
