带参数的rails任务

Question

我是 rails 任务的新手，我想在任务中执行并传递参数，然后在循环中说是或否执行其他任务（不取决于 ENV，而是取决于我的“即时”需求）。 这是代码：

我的任务：

namespace :invoices do
  desc "CREATE PDF AND SEND MAIL TASK"
  task create_and_send_pdf: :environment do
    Invoice.all.each do |invoice|
        invoice.create_and_send_pdf({send_invoice: true})
    end
  end
end

我要调用的其他函数：

def create_and_send_pdf(options = {})
    begin
        to_print = self
        ...
        if options[:send_invoice].blank? || options[:send_invoice]
            send_to_customer(to_print) 
        end
        ...

    end

    return true
end


private

    # Call mailer and send mail to customer
    def send_to_customer(invoice)
        unless invoice.send_at
            key = SecureRandom.hex(10)
            # Update invoice attibutes
            invoice.update_attributes({track_number: key, send_at: DateTime.now})
            InvoiceMailer.sample_email(invoice, key).deliver!
        end
    end

还有我的 rake 任务：

rake invoices:create_and_send_pdf

所以这是交易，如果我使用 send_invoice: false 参数执行我的任务，我不想调用 send_to_customer 函数

谢谢

Answer 1

task :create_and_send_pdf, [:send_invoice] => :environment do |task, args|
  Invoice.all.each do |invoice|
    invoice.create_and_send_pdf({send_invoice: args.send_invoice})
  end
end

rake invoices:create_and_send_pdf[true]
rake invoices:create_and_send_pdf[false]
