ruby on rails - current_user on model

Question

I need to call current_user on a model (I have installed devise). I use this method but it doesn't work:

class Todo
  def category_name
    category.try(:name)
  end

  def category_name=(name)
    self.category = Category.find_or_create_by(name: name, user_id: current_user)
  end

end

how can I fix it?

From the console, I get an error because there is no variable current_user — Giacomo Carrozzo, Feb 18 '16 at 18:14
If you try to explain what you're exactly trying to do here, then perhaps we can help. Having `current_user` in model is not really a good idea. — Surya, Feb 18 '16 at 18:15
from todo form I want to assign a category to the new todo (and create it if necessary) with the name and associate it (category) with the logged user — Giacomo Carrozzo, Feb 18 '16 at 18:39

current_user is a devise helper to be used on Views and Controllers. If you have an instance method that needs the current_user you should probably move it's logic to a Controller.

It's better explained here: Access to current_user from within a model in Ruby on Rails
