Error in creating new file

When I run this code in irb:

File.open('j1.txt','w') {|f| f.write("doc1223423")}

it works successfully. But when I do the same in a method in my controller, it gives the following error:

Errno::ENOENT (No such file or directory - file location as specified )

Why does it do that and how do I fix it?

Solved. The above file location that i was specifying didn't exist. I was doing something like this

File.open ("#{RAILS_ROOT}/jatin/j.txt", 'w+') do |f|
      f.write("blah")
    end

but the directory /jatin/ was not there, so the solution was to first create the directory and then create the file.

Dir::mkdir("#{RAILS_ROOT}/jatin")

Thanks for your help guys.

Try chagning 'w' to 'w+' - this will create a new file, 'w' just opens an existing one for writing (updating).

Here's a good round of examples that might help:
