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 .

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.
