Undefined Method 'View Render' for #{Model} w/ use of Decorator

Ruby on Rails
1

Having an odd issue involving a decorator that works inconsistently as a result of a Undefined Method 'View_Renderer error. Unless it’s a caching issue, It seems I sometimes can render inside a decorator and sometimes can’t without any tweaks to my decorator in between diagnosing this behavior.

The decorator is defined as follows:


class ProjectDecorator 

  include ActionView::Helpers 

  attr_reader :project 


  def active_model_serializer
    ProjectSerializer
  end

  def initialize(project)
    @project = project 
  end

  def self.decorate_projects(projects)
    projects.map { |project| new(project)}
  end

  class << self 
    alias_method :build_collection, :decorate_projects
  end

  # Proper Delegation 
  def method_missing(method, *args, &block)
    project.send(method, *args, &block)
  end

  def respond_to_missing?(method, include_private=false)
    project.respond_to_missing?(method) || super 
  end

  def is_decorated? 
    kind_of?(ProjectDecorator) 
  end

  def display_goals
    if project.goals.any? 
      render 'shared/goal_list', object: project
    else 
      content_tag(:strong, "This Project doesn't have goals, or it wasn't applicable for this particular project to have goals.", class: 'empty_content')
    end
  end

  def display_personas
    if project.personas.any?
      render project.personas
    else
      content_tag :strong, "This project currently doesn't have personas associated with it.", class: "empty_content"
    end

  end

  def display_attachments
    if project.attachments.any?
      render project.attachments
    else
      content_tag :strong, "This project currently doesn't have personas associated with it.", class: "empty_content"
    end

  end

  


end
