我正在挽救类似的错误
undefined local variable or method 'something' for #<PdfHelper::MyPdfHelper...................@stream="\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00\\x00........................"
这里的@stream基本上存储了整个原始pdf数据,因此错误消息非常非常长。我需要将此错误消息保存到记录中,但以更短的方式,有什么好的方法可以做到这一点,而不是仅仅将消息截断为几个字符?
我尝试将其截断为仅几百个字符,但正在寻找更好的方法。
为了更有效地处理错误消息,您可以专注于提取消息中最相关的部分,而不仅仅是截断它。这是实现它的分步方法:
这是此方法的一个示例:
begin
# Code that might raise an error
rescue => e
error_message = e.message
# Use regex to remove the raw PDF data part (assuming @stream is what you want to remove)
# The regex @stream="[^"]*" targets the @stream part of the error message and replaces it with [REDACTED]
cleaned_message = error_message.gsub(/@stream="[^"]*"/, '@stream="[REDACTED]"')
# Optionally, further reduce the size by truncating if needed
summary_message = cleaned_message.truncate(300) # Adjust the length as needed
# Save the cleaned and shortened error message to a record
ErrorLog.create(message: summary_message)
# Also log the complete error message for debugging purposes
Rails.logger.error(e.full_message)
# Or save the complete error message to a detailed error log
DetailedErrorLog.create(message: e.full_message)
end
