如何在沒有Devise的情況下在主頁上放置sign_up表單？

Question

我來到How to display a custom sign_in form anywhere in your app，它使用Devise在任何地方放置任何形式。

但我們不想使用Devise。

我已經嘗試使用：

<%= render 'sessions/new', :locals => {:session => Session.new} %> 

而且形式：

<%= simple_form_for(session, url: sessions_path) do |f| %> 

但沒有奏效。

我也試過加載會話，它也沒有工作。

有人有任何提示嗎？

before_filter :load_categories 
    protected 

    def load_categories 
    @sessions = Session.new 
    end

內的routes.rb

resources :sessions, only: [:new, :create] 

應用程序/控制器/ session_controller.rb內

class SessionsController < ApplicationController 
    def new 
    # just put empty here 
    # rails will automatically render views/sessions/new.html.erb 
    # makesure you have this file 
    end 

    # I put create and delete session in case you need it later 
    def create 
    user = User.find_by_username(params[:session][:username]) 
    if user && user.authenticate(params[:session][:password]) 
     login user 
     flash[:success] = "Anda berhasil login" 
     redirect_to yours_path 
    else 
     flash.now[:error] = 'sorry cannot login' 
     render 'new' 
    end 
    end 

    def destroy 
    session[:user_id] = nil 
    flash[:success] = "Log out" 
    redirect_to root_url 
    end 
end 

內部的意見/會話/ new.html.erb（我把樣品登錄頁面所以你可以檢查）

<%= form_for(:session, url: sessions_path) do |f| %> 
<h2>Please sign in</h2> 
    <p> 
    <%= f.label :username, "User name", class: "sr-only" %><br> 
    <%= f.text_field :username, class: "form-control", placeholder: "User name" %> 
    </p> 
    <p> 
    <%= f.label :password, class: "sr-only" %><br> 
    <%= f.password_field :password, class: "form-control", placeholder: "Password" %> 
    </p> 
    <div class="checkbox"> 
    <label> 
     <input type="checkbox" value="remember-me"> Remember me 
    </label> 
    </div> 
    <%= f.submit "Log in", class: "btn btn-lg btn-primary btn-block" %> 
    <h4> 
    <%= link_to "Reset Password?", new_password_reset_path %> 
    </h4> 
<% end %>
