ruby-on-rails - HAML:得到 "elsif"，前面没有 "if"

Question

我的 HAML 代码中需要这种构造:

- if @organisation.type == 'Company'
%p
  %strong Number of Employees:
  = @organisation.number_of_employees
- elsif @organisation.type == 'EducationalInstitution'
%p
  %strong Number of Students
  = @organisation.number_of_students

但是我得到一个语法错误:得到了前面没有“if”的“elsif”我必须如何更新我的代码才能解决错误？

您的缩进看起来可能是问题所在

- if @organisation.type == 'Company'
  %p
    %strong Number of Employees:
    = @organisation.number_of_employees
- elsif @organisation.type == 'EducationalInstitution'
  %p
    %strong Number of Students
    = @organisation.number_of_students

额外的缩进怪癖

如果评论不符合正确的缩进，则 if/else 语句失败。

例如

- if @organisation.type == 'Company'
  %p
    %strong Number of Employees:
    = @organisation.number_of_employees

-# Institutional case
- elsif @organisation.type == 'EducationalInstitution'
  %p
    %strong Number of Students
    = @organisation.number_of_students

会失败。在哪里

- if @organisation.type == 'Company'
  %p
    %strong Number of Employees:
    = @organisation.number_of_employees

- elsif @organisation.type == 'EducationalInstitution'
  -# Institutional case
  %p
    %strong Number of Students
    = @organisation.number_of_students

意志是正确的。
