Write file

Is it possibile to create with ruby css file to write in
public/stylesheets?
Obviously the name of the css file is variable and the internal
formatting is almost the same.

Thanks!

File.open(pathname, mode) {block} :

so i would do something like:

filename = “name_of_css_file.css”
css_file = File.open(RAILS_ROOT + ‘public/stylesheets’ + filename, ‘w’ )
{ |f|
f.puts “#someid { display: block; }/n” }

check out the IO, File, FileUtils classes; they are what you are looking
for.

hope it helps,

But in my Web ruby app directory where can I write the command lines?

Thank you!

you could create an create_css.rb file, place it in the lib/ directory,
and call it into any place where you want to use this method.

so you could do something like:
(UNTESTED CODE)

***** lib/create_css.rb ******

module CreateCss

# btw, this statement (file.open) returns nil
def make_css(filename, css_content)
  File.open(RAILS_ROOT + 'public/stylesheets' + filename, 'w') { |f|
            f.puts css_content }

end

end

and then, where ever in the app you want to do this (you could probably
even create the css_content with some form, and retrive it as params, or
whatever) just call the make_css method, and pass it the correct
parameters.
you’ll need to include the module, however.
example:
(UNTESTED CODE)

require ‘create_css.rb’ # includes the file
class SomeArbitraryController
include CreateCss # includes the specific module


# here you want to create the file:

def someaction
    .... # do some stuff
    make_css("a_new_css_file", params[:content_of_file])
    ... # continue doing some stuff
end

end


and walla! you should get a new file in your public folder:

 public/stylesheets/a_new_css_file.css

and if you opened it and looked at the content, it would contain the
content of params[:content_of_file].

cheers,

Google for “dry up your css” for some approaches to this kind of thing
