rails 应用程序助手不支持中文字符 [英] rails application helper didn't support chinese characters

问题描述

  def top_cateogries_with_home(category_id=-1)
    concat(raw "<select name='category_id' id='category_id'>")
    container=[]
    for category in Category.top
      container.push([category.name,category.id])
    end
    concat(raw "<option value='-1' selected>首页</option>")
    concat(raw options_for_select(container, selected = nil))
    concat(raw "</select>")
  end

我写了一个辅助方法application_helper.rb，但是它会抛出问题，如果容器中文字符首页，如果我用数字或其他字符替换它们，没关系，

i write a helper method a application_helper.rb,but it will throw issue,if container chinese character 首页,if i replace them with number or other character, it's ok,

我可以使用带有中文字符的注释，但是如果我想在助手中使用它会抛出错误，也可以用ror很好地显示数据库中的中文数据，

i can use comment with chinese character,but if i want to use in helper it throw error, also in the database's chinse data can display with ror well,

希望有人能帮助我，谢谢

hope someone could help me,thanks

推荐答案

尝试将魔术注释 # coding: utf-8 添加到 application_helper.rb 的开头

Try adding the magic comment # coding: utf-8 to the beginning of your application_helper.rb

如果您在 Ruby 1.9 上运行，则需要它.你也可以把它添加到你所有的 .rb 文件

It is needed if you are running on Ruby 1.9. You may as well add it to all your .rb files
