Say I have a form for entering subject marks (separate model) and I want to enter marks for students from a specific classroom from a select box. How do I upload all students based on the classroom I select and have them line up next to marks field
Classroom > One
Student Name - Mark
Steve Wonder - _______
Roman Reigns - _______
Banana Mike - _______
Rona Meakins - _______
There are many ways to solve this. I'll go with the simplest one and let's say you use simple form.
What you basically want to do is something like this:
form_for @class do |f|
# Here you can either loop trough the number of students here or make JS method call from a button to create a new instance of the div below for each student you want to add
f.simple_fields_for :students do |student_form|
# Here you have all simple_form methods available
student_form.input :score
end
f.button :submit
end
