How to use "count" in rails to show how many projects/tasks user has?

Question

I defined method 'count' in my tasks controller as:

def count
  @count = current_user.tasks.count
end

I'm not sure how to show that in my tasks views. Do I just use Tasks count: <% @count %>? How do I get in my view how many tasks the user has?

Thanks

First of all, controller methods can't be called directly inside views, instead you need to use helper methods, however Rails still can help you DRY your code and declare a method in controller to to be a helper method that can be used in helpers and views. You can do that by adding this line in the body of Tasks controller:

helper_method :count

Then inside your view you can just do

<%=count%>

Btw you can redefine the count method as follows:

def count
  current_user.tasks.count
end

However I don't find a reason why you want to define a method for this in the controller. Were you I would call this directly in the view:

<%=current_user.tasks.count%>
