Ruby on rails 无法使用acts_as_xlsx gem显示列标题

我正在使用acts_as_xlsx gem在rails中生成excel报告。我按照示例创建列标题，将它们添加到en.yml文件中，并在模型中包括：i18n=>true，但行为空。所有其他数据都显示正确

控制器：

def index
  @claims = Claim.all

  respond_to do | format |
    format.html # index.html.erb
    format.json { render :json => @claims }
    format.xlsx {

    xlsx_package = Claim.to_xlsx :name => "Claims", 
                               :header_style => {:bg_color => "377", 
                               :fg_color => "FF",  
                               :sz => 16, 
                               :alignment => { :horizontal => :center }}
    begin
      temp = Tempfile.new("claims.xlsx")
      xlsx_package.serialize temp.path
      send_data xlsx_package.to_stream.read, :filename => 'claims.xlsx', :type=> "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"
    ensure
      temp.close
      temp.unlink
    end
  }  
  end
end

acts_as_xlsx :columns => [:id, :business_unit_id, :created_at, :updated_at, :claim_number], :i18n => true

en:
  activerecord:
    attributes:
      claims: Claims
      claim:
        id: "Claim Id"
        business_unit_id: "Business Unit"
        created_at: "Created at"
        updated_at: "Updated at"
        claim_number: "Claim Number"

型号：

def index
  @claims = Claim.all

  respond_to do | format |
    format.html # index.html.erb
    format.json { render :json => @claims }
    format.xlsx {

    xlsx_package = Claim.to_xlsx :name => "Claims", 
                               :header_style => {:bg_color => "377", 
                               :fg_color => "FF",  
                               :sz => 16, 
                               :alignment => { :horizontal => :center }}
    begin
      temp = Tempfile.new("claims.xlsx")
      xlsx_package.serialize temp.path
      send_data xlsx_package.to_stream.read, :filename => 'claims.xlsx', :type=> "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"
    ensure
      temp.close
      temp.unlink
    end
  }  
  end
end

acts_as_xlsx :columns => [:id, :business_unit_id, :created_at, :updated_at, :claim_number], :i18n => true

en:
  activerecord:
    attributes:
      claims: Claims
      claim:
        id: "Claim Id"
        business_unit_id: "Business Unit"
        created_at: "Created at"
        updated_at: "Updated at"
        claim_number: "Claim Number"

En.yml:

def index
  @claims = Claim.all

  respond_to do | format |
    format.html # index.html.erb
    format.json { render :json => @claims }
    format.xlsx {

    xlsx_package = Claim.to_xlsx :name => "Claims", 
                               :header_style => {:bg_color => "377", 
                               :fg_color => "FF",  
                               :sz => 16, 
                               :alignment => { :horizontal => :center }}
    begin
      temp = Tempfile.new("claims.xlsx")
      xlsx_package.serialize temp.path
      send_data xlsx_package.to_stream.read, :filename => 'claims.xlsx', :type=> "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"
    ensure
      temp.close
      temp.unlink
    end
  }  
  end
end

acts_as_xlsx :columns => [:id, :business_unit_id, :created_at, :updated_at, :claim_number], :i18n => true

en:
  activerecord:
    attributes:
      claims: Claims
      claim:
        id: "Claim Id"
        business_unit_id: "Business Unit"
        created_at: "Created at"
        updated_at: "Updated at"
        claim_number: "Claim Number"

它不起作用的原因是您使用的en.yml文件是复数形式的索赔，您应该使用索赔

en:
  activerecord:
    claim:
      id: "Claim Id "
      business_unit_id: "Business Unit "
      created_at: "Created at "
      updated_at: "Updated at "
      claim_number: "Claim Number "

我认为i8n应该使用的开关实际上是基于最新文档的“activerecord.attributes”

:i18n => "activerecord.attributes"

另一方面，我认为您需要在标题后添加空格，否则表单中显示的标题将无法正确隔开。

好的，我意识到问题在于Mac上的预览（因为我没有excel）。当我将文档上传到google drive时，我在列标题中看到了文本（注意：我还删除了：fg_color=>“FF”，因此我的字体在黄色背景上不是白色的）。即使进行了这些更改，我仍然不确定为什么我可以使用预览在其他行中看到数据，但在列标题行中看不到数据。但是数据正确地填充了字段。
