How to make user_helper correctly?

Question

Ruby on Rails

I want to make a helper for avatars, but even it doesn’t work
. In general, what we have:

module UsersHelper
  def avatar_for(user, options = { size: 50 })
    if user.nil? or user.avatar.nil?
      image_tag('/uploads/1.png', :size => 50)
      size = options[:size]
    else
      image_tag(user.avatar.thumb, :size => 52)
      size = options[:size]
    end
  end
end

I insert it into the view
<%= avatar_for @user %>
But it doesn't work, I use carierwave and rmagick for cropping.
Yes, by the way, can anyone come across crop? What do you advise?

Answer 1

The task is clear, but it looks like this:

module UsersHelper
  def avatar_for(user, options = { size: 50 })
    if user.try(:avatar).blank?
      image_tag('/uploads/1.png', :size => options[:size])
    else
      image_tag(user.avatar.thumb, :size => options[:size])
    end
  end
end

It's not clear what you're doing size = options[:size]here. You need to pass size to image_tag, but in fact your helper just outputs options[:size] instead of image_tag.
