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:
Subject Model
has_many :questions
Controller
def index
@subjects = Subject.order(:title)
@question_number = Question.find(???).count
…
View
<% @subjects.each do |subject| %>
<%= subject.title %> (<%=@question_number %>)
The questions table has a subject_id attribute and this is what I want
to query on
Best way to find the count for each subject in the @subjects
hash and then display with the associated subject?

Can’t understand how to find the count for each subject in the @subjects
hash and then display with the associated subject
<%= subject.questions.count %> doesn’t work?
