Error in creating new file

Rails
1

In my controller method, I am doing this

      File.open ("#{RAILS_ROOT}/directory/

#{params[:file_name]}.#{params[:file_type]}", ‘w’) do |f|
f.write(params[:file_body])
end

but I am getting this error

       NoMethodError (undefined method ` ' for

#ProgramsController:0xb66b4354):

I have tried passing the absolute path and still it doesn’t work. And
I have also tried escaping the whitespace between “.open” and
“(”…still doesn’t work.
I don’t know what I am doing wrong and how can I fix it?

Hi Jatin K.,

It’s work for me. I am testing this on console. Please try this.

file_name = “test”
=> “test”

ext_name = “txt”
=> “txt”

File.open("#{RAILS_ROOT}/directory/#{file_name}.#{ext_name}", “w”) do |f|
f.write(“Hello World!”) end
=> 12
