Index View Error wrong amount of arguments

I'm getting an argument error and I am not to sure why. I am still fairly new to using Rails and programming overall. I am currently working on my index page and am just trying to get the description displayed. Below is the view and controller. I am not sure why t.description is being expected to have more than one argument. Is this because of strong params?

View:

<h1> All Tea Blends </h1>

<% @teas.each do |t| %>
  <h2><%= link_to t.flavor, tea_path(t.id)%> - <%= t.brand.name %></h2>
  <% link_to "Write a review", new_tea_review_path%>
<% end %>

<div>
    <p><%= t.description %></p>
</div>

Controller:

class TeasController < ApplicationController
  def index
    @teas = Tea.order_by_rating.includes(:brand)
  end
end

t.description is outside of the loop. Not sure why you'd get wrong number of arguments (t is also used for translations, though). Just move it inside the loop...

<% @teas.each do |t| %>
  <h2><%= link_to t.flavor, tea_path(t.id) %> - <%= t.brand.name %></h2>
  <% link_to "Write a review", new_tea_review_path %>

  <div>
    <p><%= t.description %></p>
  </div>
<% end %>

I'd also recommed changing your loop variable to tea instead of t. Its more descriptive and avoids conflicts.
