我想将我的rails应用生成的结果导出为excel格式。 distribution_sheet,结果和标本都是模型。这是我的控制器中的脚本:
def first
@distribution_sheet = DistributionSheet.find(:all, :conditions => ["lifecycle_state = ?","closed"]).last
@results = @distribution_sheet.results
@specimens = @distribution_sheet.specimens
end
include DisplayResultHelper
def show
respond_to do |format|
format.html
format.csv {
@specimens.each do |sp|
send_data(generate_csv([["Lab No","Assay","Batch","Cuttoff"],[sp.id]]),
:filename => "my_data-#{Time.now.to_date.to_s}.csv",
:type => 'text/csv')
end
}
format.xls{
send_data(generate_xls([["Lab No","Assay","Batch","Cuttoff"],[]]),
:filename => 'my_date.xls',
:type => 'application/vnd.ms-excel')
}
end
end
end
如果我在数组中添加任何单词,这是有效的,但是一旦我添加sp.id就失败了。我想在sp.id中添加数据。有线索吗?

我不确定您使用的是哪个库 - 但也许它需要在这些数组中使用真正的字符串,因此请尝试传入sp.id.to_s
而不仅仅是sp.id
