Each loop in Ruby on Rails

Question

So I have this following request:

{"utf8"=>"✓",
 "student_work"=>{"work_experiences_attributes"=>{"1415498778636"=>{"company_name"=>"Company1",
 "start_year"=>"2014",
 "end_year"=>"2014",
 "job_title"=>"Title1",
 "job_description"=>"test1"},
 "1415498795509"=>{"company_name"=>"Company2",
 "start_year"=>"2014",
 "end_year"=>"2014",
 "job_title"=>"Title2",
 "job_description"=>"Test2"}}},
 "commit"=>"Next"}

or to make it easier:

student_work[work_experiences_attributes][1415498778636][company_name]:Company1
student_work[work_experiences_attributes][1415498778636][start_year]:1
student_work[work_experiences_attributes][1415498778636][start_year]:2014
student_work[work_experiences_attributes][1415498778636][end_year]:2
student_work[work_experiences_attributes][1415498778636][end_year]:2014
student_work[work_experiences_attributes][1415498778636][job_title]:Title1
student_work[work_experiences_attributes][1415498778636][job_description]:test1
student_work[work_experiences_attributes][1415498795509][company_name]:Company2
student_work[work_experiences_attributes][1415498795509][start_year]:3
student_work[work_experiences_attributes][1415498795509][start_year]:2014
student_work[work_experiences_attributes][1415498795509][end_year]:4
student_work[work_experiences_attributes][1415498795509][end_year]:2014
student_work[work_experiences_attributes][1415498795509][job_title]:Title2
student_work[work_experiences_attributes][1415498795509][job_description]:Test2

How do I access each values using the each loop in Ruby? I am still new to Ruby, please help. Thanks

Update Those number (1415498778636 and 1415498795509) is always changing, so the loop must be able to handle any different kind of numbers

In future, please simplify your example as much as possible. Here, for example, there are many key-value pairs that could be removed without making the example less meaningful. Also, shortening names makes it more readable. — Cary Swoveland

params['student_work']['work_experiences_attributes'].values.each do |hash|
  hash.each do |key, value|
    # ...

end

Actually as student_work[work_experiences_attributes] is a Hash, so you can just use each method.

You mean response instead request right? You could do:

attr=params[:student_work].keys.each do |key|
    key.to_i > 0
end[0] 
params[:student_work][attr].each do |key, value|
# do something
end
