link_to in Rails 7

Question

I am new to Ruby on Rails and I am making a view page showing a table from the database. I want to add a link_to to delete this record. I tried the code written below and nothing worked for me.

The browser keeps refreshing and does nothing.

ruby 3.1.2 Rails 7.0.4

<%= link_to 'Delete', @friend, data: {turbo_method: :delete, turbo_confirm: 'Sure?'}, class: "btn btn-danger" %>

also with this

<%= link_to 'Delete', @friend, method: :delete, data: { confirm: 'Are you sure?' }, class: "btn btn-danger" %>

html.erb code

<p style="color: green"><%= notice %></p>

<%= render @friend %>

<div>
  <%= link_to "Edit this friend", edit_friend_path(@friend) %> |
  <%= link_to "Back to friends", friends_path %>

  <%#= button_to "Destroy this friend", @friend, method: :delete,data: {turbo_confirm: 'Are you sure?'} %>
  <%#= button_to "Destroy this friend", @friend, method: :delete,data: {turbo_confirm: 'Are you sure?'} %>
  <%= link_to 'Delete', @friend, method: :delete, data: { confirm: 'Are you sure?' }, class: "btn btn-danger" %>
</div>

Controller code

class FriendsController < ApplicationController
  before_action :set_friend, only: %i[ show edit update destroy ]

  # GET /friends or /friends.json
  def index
    @friends = Friend.all
  end

  # GET /friends/1 or /friends/1.json
  def show
  end

  # GET /friends/new
  def new
    @friend = Friend.new
  end

  # GET /friends/1/edit
  def edit
  end

  # POST /friends or /friends.json
  def create
    @friend = Friend.new(friend_params)

    respond_to do |format|
      if @friend.save
        format.html { redirect_to friend_url(@friend), notice: "Friend was successfully created." }
        format.json { render :show, status: :created, location: @friend }
      else
        format.html { render :new, status: :unprocessable_entity }
        format.json { render json: @friend.errors, status: :unprocessable_entity }
      end
    end
  end

  # PATCH/PUT /friends/1 or /friends/1.json
  def update
    respond_to do |format|
      if @friend.update(friend_params)
        format.html { redirect_to friend_url(@friend), notice: "Friend was successfully updated." }
        format.json { render :show, status: :ok, location: @friend }
      else
        format.html { render :edit, status: :unprocessable_entity }
        format.json { render json: @friend.errors, status: :unprocessable_entity }
      end
    end
  end

  # DELETE /friends/1 or /friends/1.json
  def destroy
    @friend.destroy

    respond_to do |format|
      format.html { redirect_to friends_url, notice: "Friend was successfully destroyed." }
      format.json { head :no_content }
    end
  end

  private
    # Use callbacks to share common setup or constraints between actions.
    def set_friend
      @friend = Friend.find(params[:id])
    end

    # Only allow a list of trusted parameters through.
    def friend_params
      params.require(:friend).permit(:first_name, :last_name, :email, :phone, :twitter)
    end
end

Your code should work

<%= link_to 'Delete', @friend,
  data: {turbo_method: :delete, turbo_confirm: 'Sure?'}, class: "btn btn-danger" %>

But more reliable to use button_to that generate form tag with button

<%= button_to 'Delete', @friend,
  method: :delete, form: {data: {turbo_confirm: 'Sure?'}}, class: "btn btn-danger" %>
