Removing just leading and trailing newline characters

Rails
1

Hi:

I am using FCKeditor in one of my form, when i copy and paste something
into it using WordPaste, it appends few newlines at the beginning and at
the end.
How can i strip just those \n without effecting the inbetween newlines
and the formatting.

TIA,
Priya

you may use strip

http://ruby-doc.org/core/classes/String.src/M000820.html
or any else as required .

way i want but inside code it isn’t solving the purpose.

Hi:

Its a simple form to create a job. FCKeditor has been placed with the
name job[description].
At the create event, it assigns the value to @job.description.
I was trying to strip it before saving like:
@job.description = params[:job][:description].strip, but it isnt solving
the purpose.

In the db, the description field shows a number of blank lines at the
beginning and end.

try this
*validate :striped_descriptions

def striped_descriptions

striping_description

unless self.description.nil?
    logger.debug 'self.description before strip'
    logger.debug self.description
    striped_description = (self.description).strip
    self.description = striped_description
    logger.debug 'self.description after strip'
    logger.debug self.description

end
end
*
or
try this

*before_save :striped_descriptions

def striped_descriptions

striping_description

unless self.description.nil?
    logger.debug 'self.description before strip'
    logger.debug self.description
    striped_description = (self.description).strip
    self.description = striped_description
    logger.debug 'self.description after strip'
    logger.debug self.description

end
end

This is probably best done with a regular expression.

Isn’t this just what String#strip does?

No. Strip removes all whitespace, not just newlines.
