[RUBY] [Rails withdrawal] Create a simple withdrawal function with rails

[Rails withdrawal] Create a withdrawal function with rails

Prerequisites

Model: User model Controller: Users controller Routing: resources: describe users

Implementation process design before adding functions

(1) Acquire a record using the User id as a key, as in the case of adding the posting function. (2) Delete the record using the destroy method.

Let's actually do it!

Tinker with Users_controller.rb

`users_controller`


class UsersController < ApplicationController
  def destroy
    @user = User.find(params[:id]) #Get information with a specific id
    @user.destroy
    flash[:success] = 'The user has been deleted.'
    redirect_to :root #If the deletion is successful, return to the root page
  end
end

Tinker with view

`erb:〇〇.html.erb`


<%= link_to "Withdraw",user_path(current_user.id), class: "destroy-user",method: :delete %>

<%#here,(current_user.id)Pass the login user's id as an argument!

That's it! I couldn't make an advanced withdrawal function yet ... For the time being! !! Once with this!
