How to use rendear
By using the render method, you can display the view directly without going through another action.
Specify the view you want to display, such as ** render (“folder name / file name”) **.
If you use the render method, you can use the @variable defined in the action as it is in the view, unlike the case of using the redirect_to method.
class UserController < ApplicationController def top @user = User.find_by(email: params[:email], password: params[:password]) if @user else render ("home/signup") end end end
