Rails resend email activation

Question

I am having trouble setting up a resend activation email. When the user creates an account the email sends perfectly, but when they try to resend the activation email I am getting and error. Thanks in advance for all the help.

This is the error

ActionController::UrlGenerationError in Sessions#resend_activation

No route matches {:action=>"edit", :controller=>"account_activations", : email=>"[email protected]", :id=>nil}, possible unmatched constraints: [:id]

This is the line its highlighting in account_activation.html.erb

<%= link_to edit_account_activation_url(@user.activation_token, email: @user.email) do %>

routes.rb

resources :account_activations, only: [:edit]

get '/resend_page', to: 'sessions#resend_account_activation_page'
post 'resend_activation', to: 'sessions#resend_activation'

resend_account_activation_page.html.erb

  <div class="FormBody">
      <h1 style="margin-bottom:30px">Account Activation</h1>

      <p> If you need the activation email to be resent enter the email you signed up with and hit the resend button. </p>
        <%= form_for(:sessions, url: resend_activation_path) do |f| %>

          <div>
              <%= f.text_field :email, class: "Input", placeholder: "Email"%>
          </div>

           <%= f.submit "Resend", class: "SignUpButton", data: {toggle: "tooltip"}, title: "Resend" %>
       <% end %>
    </div>

      @user.send_activation_email

      redirect_to root_url
    else
      flash.now[:danger] = 'Email is not asociated with any account, please sign up first.'
      redirect_to root_url
    end
  end

      log_in user
      flash[:success] = "Account activated!"
      redirect_to root_url
    else
      flash[:danger] = "Invalid activation link"
      redirect_to root_url
    end
  end
end

def account_activation(user)
  @user = user
  mail to: user.email, subject: "Account Activation"
end

I figured it out I forgot I had to call the create_activation_digest before I sent out the email so it creates a new token. Thanks for the help!

def create_activation_digest
  self.activation_token  = User.new_token
  self.activation_digest = User.digest(activation_token)
  update_columns(activation_digest: User.digest(activation_token))   
end
