Hi All,

      I have established the relationship and everything is working well, but I need to display as descried below.

I have two tables Student and Teacher.

In my application one teacher has several students under him, so how do I display the students under only that particular teacher at a given time.

Thank You

teacher model: has_many :students

student model: belongs_to :teacher

in controller: @teacher = Teacher.find(...your code...)

then all his students can be accessed: @teacher.students

for example @teacher.students.each do |student| ...do something with student end

How to student as a nested resource to teacher. Such that when I perform a show action an albums, I should be able to view only the photos associated with it and not all the photos of the table
