I am quite new in Ruby-on-rails. And I have a very simple question: This one works in my view file:
- @posts.each do |child|
= child.name
end
However, I can't create a helper method which takes an array as argument and iterate it with 'each'.
In my view file:
=f1(@posts)
In my helper file:
def f1(abc)
abc.each do |child|
puts child.name
end
end
Please help me out with this silly problem. Thanks a lot in advance
Does something like this work?
def f1(abc)
output = ''
abc.each do |child|
output << "<br/> #{child.name}"
end
output
end
In a running rails app puts outputs into the log file.
I recommend trying this approach:
Create a '_post' partial in the posts view directory, then put what you want to render out using post as the object (ie: post.name) then use render @posts in the view. This will automagically render the partial for each object in the collection.
See section 3.4.5 in the Ruby on Rails Layouts and Rendering Guide for more info
