Link_to in view that redirects to another view by id-CodePudding

So i have 2 models Users and books. Books has user_id,name, User has name,adress. Both have views. I did create a link_to in user view to redirect to books view, but i want to redirect by id.

What i mean if i click in User1 link_to, i want to view only user1 books(books that have only user_id:1 if it is possible to see the most recent created at the beginning, so if i have created book.id=5 would get first and book.id=1 would be lastone).

User model:

Class User < ApplicationRecord
has_many :books

Book Model:

Class Book < ApplicationRecord
belongs_to :user

Controller book show:

def show 
 @book = Book.all
end

if you need anything else, just ask in comments and i will edit. Also sorry if im not explaining correctly.

CodePudding user response：

In your books#index controller action

def index
  @books = Book.all
  @books = @books.where(user_id: params[:user_id]) if params[:user_id].present?
end

And in your users#show view

link_to "This user books", books_path(user_id: @user.id)

So if you will go to /books you will see all books

But if you click the link on user's page -- you will see only this user books

CodePudding user response：

For me, the best soluction is leave the default methods and create a new one:

def show_user_books
  @books = Book.where(user_id:params[:user_id]).order(created_at: :desc) if params[:user_id].present?

  redirect_to books_path 
end
