I am trying to count the number of questions in each subject and then
display the question count for each subject next to the subject name:
Model
has_many :questions
Controller
def index
@subjects = Subject.order(:title)
@question_number = Question.find(???).count
end
end
View
<a href="/.../<%= subject.id %>"><%= subject.title
%> (<%@question_number %>)</a>
The questions table has a subject_id attribute and this is what I want
to query on
Can''t understand how to find the count for each subject in the
@subjects
hash and then display with the associated subject
