Adding a Drop down doesn't work

It won't show a drop down when I follow the tutorial steps. Adding a Dropdown

_form.html.erb

<%= simple_form_for(@status, html: {class: "form-horizontal"}) do |f| %>
  <% if @status.errors.any? %>
    <div id="error_explanation">
      <h2><%= pluralize(@status.errors.count, "error") %> prohibited this status from being saved:</h2>

      <ul>
      <% @status.errors.full_messages.each do |msg| %>
        <li><%= msg %></li>
      <% end %>
      </ul>
    </div>
  <% end %>

  <div class="field">

  </div>

   <%= f.input :user_id, collections: User.all, label_method: :full_name %>
   <%= f.input :content %>
  <div class="form-actions">
    <%= f.button :submit %>

Found the issue

<%= f.input :user_id, collection**s**: User.all, label_method: :full_name %>

Should be

<%= f.input :user_id, collection: User.all, label_method: :full_name %>

Ty for help

Do you have more than 1 user in your system? Try adding a few more users.

I have more than one user but I am having this same issue. What should I do? I'm using windows OS.

Found a potential fix!

Try this: 1) go to models/user.rb

2) Make the defined full name is exactly like this:

def full_name
    first_name + " " + last_name
end

3) Retry loading the page.

4) If it still doesn't work, copy and paste this in your _form.html.erb (I like having profile_name > full_name:

<%= simple_form_for(@status, html: {class: "form-horizontal"}) do |f| %>
    <% if @status.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(@status.errors.count, "error") %> prohibited this status from being saved:</h2>
 <ul>
<% @status.errors.full_messages.each do |msg| %>
    <li><%= msg %></li>
    <% end %>
    </ul>
   </div>
<% end %>
  <%= f.input :user_id, collection: User.all, label_method: :profile_name %>
  <%= f.input :content %>
  <div class="form-actions">
    <%= f.button :submit %>
  </div>
<% end %>`
