Rails: path of file

Question

I have inside app a directory called csv and inside this dir I have a file called names.csv I want to use File.read(path:string)

Answer 1

file = File.join(Rails.root, 'app', 'csv', 'names.csv')
File.read(file)

Answer 2

Rails.root points to the top folder of your rails project, so the path would be:

File.read(File.join(Rails.root, 'app','csv','names.csv'))

Answer 3

You should do: Rails.root.join "app", "csv", "names.csv"

Rails.root returns a PathName object. PathName has a join method which takes any number of arguments and appends it to the pathname to create the new path.

Read on PathName#join here:

http://www.ruby-doc.org/stdlib-1.9.3/libdoc/pathname/rdoc/Pathname.html#method-i-join

Answer 4

Thanks for above answers, It also worked this way for me:

"#{Rails.root}/public/spreadsheets/file_name.xlsx"
