For simplicity, am using an easy example.
I have a controller method:
def test
@books.each do |book|
@book_id = "EMI:#{book.id}"
@book_test = ....(some function)
end
end
How do I pass the '@book_id' & '@book_test' values from the loop to the view page?
Please note that I don't want to repeat the code in the view page. Just want to pass the values in the loop to the view page.
You have @books in the test method then why you are making your loop in that method? Do it in your view file directly no repetation needed.
Or other wise make two arrays like @book_ids and @book_tests and collect your prepared values and use them in your views like the following:
def test
@book_ids=[]
@book_tests=[]
@books.each do |book|
@book_ids << "EMI:#{book.id}"
@book_tests << ....(some function)
end
end
Your controller takes unnecessary works it should have.
The jobs are better for Model, from what I've seen in the question
class Book < ActiveRecord::Base
def book_id
"EMI:#{self.id}"
end
def book_tests
"some function"
end
end
# Then in the view
@books.each |book| do
book.book_id
book.book_tests
end
Isn't this way cleaner?
