您如何将这种多行失败转换为 HAML？

我无法完全理解这一点。

原始：

<%=
Shasta::CSV.generate do |csv|
  csv << ["Customer", "Job Name", "Payment Date", "Amount", "Notes"]

  for payment in @payments
    csv << [
      payment.customer.name,
      payment.jobs.map(&:name).join(" "),
      I18n.l(payment.created_at, :format => :short_date),
      number_to_currency(payment.amount),
      payment.notes
    ]
  end
end.html_safe
%>

HTML2HAML 将其转换为此，但失败

= Shasta::CSV.generate do |csv|                                        |
    csv << ["Customer", "Job Name", "Payment Date", "Amount", "Notes"] |
    for payment in @payments                                           |
      csv << [                                                         |
        payment.customer.name,                                         |
        payment.jobs.map(&:name).join(" "),                            |
        I18n.l(payment.created_at, :format => :short_date),            |
        number_to_currency(payment.amount),                            |
        payment.notes                                                  |
      ]                                                                |
    end                                                                |
  end.html_safe                                                        |

I can't quite wrap my mind around this.

Original:

<%=
Shasta::CSV.generate do |csv|
  csv << ["Customer", "Job Name", "Payment Date", "Amount", "Notes"]

  for payment in @payments
    csv << [
      payment.customer.name,
      payment.jobs.map(&:name).join(" "),
      I18n.l(payment.created_at, :format => :short_date),
      number_to_currency(payment.amount),
      payment.notes
    ]
  end
end.html_safe
%>

HTML2HAML Converted it to this, but it fails

= Shasta::CSV.generate do |csv|                                        |
    csv << ["Customer", "Job Name", "Payment Date", "Amount", "Notes"] |
    for payment in @payments                                           |
      csv << [                                                         |
        payment.customer.name,                                         |
        payment.jobs.map(&:name).join(" "),                            |
        I18n.l(payment.created_at, :format => :short_date),            |
        number_to_currency(payment.amount),                            |
        payment.notes                                                  |
      ]                                                                |
    end                                                                |
  end.html_safe                                                        |

这并不完全是您问题的答案，但编写多行 haml 语句很痛苦，这就是为什么您应该将其移至助手中。

= some_descriptive_method_name @ payments

def some_descriptive_method_name(payments)
  Shasta::CSV.generate do |csv|
    csv << ["Customer", "Job Name", "Payment Date", "Amount", "Notes"]

    payments.each do |payment|
      csv << [
        payment.customer.name,
        payment.jobs.map(&:name).join(" "),
        I18n.l(payment.created_at, :format => :short_date),
        number_to_currency(payment.amount),
        payment.notes
      ]
    end
  end.html_safe
end

This isn't exactly the answer to your question, but it's a pain to write multiple line haml statements which is why you should probably move it into a helper.

= some_descriptive_method_name @payments

def some_descriptive_method_name(payments)
  Shasta::CSV.generate do |csv|
    csv << ["Customer", "Job Name", "Payment Date", "Amount", "Notes"]

    payments.each do |payment|
      csv << [
        payment.customer.name,
        payment.jobs.map(&:name).join(" "),
        I18n.l(payment.created_at, :format => :short_date),
        number_to_currency(payment.amount),
        payment.notes
      ]
    end
  end.html_safe
end
