如何从Rails的simple_format（）输出中删除空格？

Question

I am using Rails' simple_format() to output addresses from my database like this:

<%= simple_format(@person.address) %>

As I result I get this markup in my Safari browser:

<p>
  "John Doe "<br>
  "123 Main Street "<br>
  "Eggham "<br>
  "United Kingdom"<br>
</p>

This is fine as long as the text appears left aligned.

When I want the text to appear right aligned, however, the right edge is not straight. If you look closely at the HTML, you'll see why. On all lines there are blanks at the end, except for the last one.

I don't understand where these blanks come from because I always pressed return immediately after entering the last letter of each line. I never entered any of these blanks, yet they appear in every address that simple_format() gives me.

Is there another or better way to print out a textfield in Rails without those annoying blanks at the end?

Thanks for any help.

Answer 1

OK, I ended up using this helper method:

def print_multiline(field)
  field.gsub("\r\n","<br/>").html_safe
end

For me this works much better than simple_format() because it won't create whitespace at the end of lines.

I use it in my views like this:

<%= print_multiline(@person.address) %>

input_string.gsub（“\\ r \\ n”，“\\ n”）将用Unix风格的LF字符替换Microsoft风格的CR / LF。
