can't read multipe text files through a loop in ruby on rails -

i trying read multiple text files @ time. first line making difference between text files while text files name same. using following code can read 1 text file not whole. please me out. here controller code

def index   dir.chdir("/home/sbrc/sukanta/opengrok")    @f = dir.glob("**/*.txt")     = 0   @params = []   while i<@f.length     data = io.readlines("/home/sbrc/sukanta/opengrok/"+@f[i])      if  data[0] == "jbp prod\n"        #@project = data[1]       # @cl = data[4]       @params = data[1]     end     i+=1   end  end 

my view file code , showing undefined method `each' "aruba-i8262-slim-03\n":string "aruba-i8262-slim-03\n 2nd line of text.

<% @params.each |pro| %>  <%= pro %> <% end %> 

here getting data 1 text file

try change line

@params = data[1] 

to

@params << data[1] 

or better refactor code bit, like

def index   @params = []   dir.glob("/home/sbrc/sukanta/opengrok/*.txt") |file|     data = io.readlines(file)     @params << [data[1], data[4]].join('@') if  data[0] == "jbp prod\n"   end end
