提交关注者表单后页面出错

我在rails控制台中的关注者#create方法中执行所有命令，它可以正常工作。但由于某些原因，当我在页面上执行表单时，它似乎没有保存用户，然后我在页面上收到此错误。有任何想法吗？不确定它是否与我的路线有关，所以我也会发布它们。

routes.rb中：

TwitterApp::Application.routes.draw do
    get "followers/show"
    get "followers/new"
    get "dashboard/new"
    get "users/new"
    get "users/edit"
    get "sessions/new"
    get "add_follower" => "followers#new", :as => "add_follower"
    #get '/followers/:id', to: 'followers#show', as: 'followers'

    get '/like/:id', to: 'followers#like', as: 'like'
    get "log_out" => "sessions#destroy", :as => "log_out"
    get "" => "sessions#new", :as => "log_in"
    get "sign_up" => "users#new", :as => "sign_up"
    get "settings" => "users#edit", :as => "settings"
    get "dashboard" => "dashboard#new", :as => "dashboard"
    root :to => "sessions#new"
    resources :users
    resources :sessions
    resources :followers
end

追随者表格：

<%= @follower_to_save.inspect %>
                        <h3>Add Follower: </h3>
                        <%= form_for @follower do |f| %>
                            <% if @follower.errors.any? %>
                                <div class="error_messages">
                                    <h2>Form is invalid</h2>
                                    <ul>
                                        <% for message in @user.errors.full_messages %>
                                            <li><%= message %></li>
                                        <% end %>
                                    </ul>
                                </div>
                            <% end %>
                            <%= f.text_field :follower_username, class: "form-control", autofocus: "", required: "", placeholder: "Twitter Username" %><br/>
                            <p class="button"><%= submit_tag "Add", class: "btn btn-lg btn-primary btn-block" %></p>
                        <% end %>
