Question

I was refactoring a bit of code in a project for work when I came across an odd bit of syntax. I confirmed it has been in the file since it was first created and the bit of code is being called.

worksheet.each 1 do |row|
  Dashboard::LocalizedMessagingField.create({blah blah blah})
end

When I run something like the following in irb it complains about 1 for 0 parameters on each.

[1,2,3].each 1 do |i|
  puts i
end 

Why does it work in the RoR application? Anyone ever see something like this before?

Answer 1

I found the answer after a bit of digging. We have the Spreadsheet gem installed and it provides an each method that takes a parameter to skip the first n rows of a spreadsheet.

def each skip=dimensions[0], &block
  skip.upto(dimensions[1] - 1) do |idx|
    block.call row(idx)
  end
end
