I've got a iteration (in my view):
([email protected]_i).each do |i|
...doing things...
@bigtable << @result[0..result.length-2]
end
Every @result is a string. @bigtable has every @result from iterations. Now what I want: I want to save content from the @bigtable (after clickin a button) to .csv file (and choose where to save it on my hdd). And I want do it like every @result from @bigtable is in its own single line, like this (pseudo code):
@result string from @bigtable[0]
@result string from @bigtable[1]
etc.
Please, help

First, open the text file for writing (or append) using the open() function. Second, write to the text file using the write() or writelines() method. Third, close the file using the close() method.
You can use int fprintf(FILE *fp,const char *format, ...) function as well to write a string into a file.
fputs() is used to write a string to a file.
To transform your array into a string you can do :
@bigtable.join("\n")
To write this string into a file :
File.open("path/to/file", "w") { |file| file.write @bigtable.join("\n") }
And that's it!
BTW:
@result[0..result.length-2] == @result[0..-2]
