how to set multiple default form values on submission in rails? - ruby-on-rails

Question

attendance table that takes has attribute status, date,recuritment_id, and project_site_id .
project_site has one_to_many association with attendance
recuritmenthas one_to_many association with attendance.
i am taking attribute from recruitment table when attribute status is joined in attendance#form view.
<% (1..(Time.days_in_month #project_site.attendance_month.strftime("%m").to_i)).each do |date| %>
here #project_site.attendance_month contains the attendance month value. based on month i calculate number of days column along with name from recuritmnet table.
here is view-
holydays master contains corresponding month holyday's date and in view it auto match date and prints "H",
All input default selected as P. there is final submission_button that chnages boolean attribute. now on final submission i want to push all default selected P into attendance table.
attendance_controller.rb
def new
if #project_site.submission_status == false
#attendance = Attendance.new
#date = HolydayCalendar.all
#recruitment = Recruitment.all.where(current_status: "2")
else
redirect_to project_site_attendances_path
end
end
from.html.erb (attendance controller view)

It's a little unclear what your question is, but I gather it has to do with your form sending back an array op options.
If you want your html form to return an array of information, then you need to indicate it in your html using the name = "attendance[]" syntax, notice the square brackets.
