            <th>Type</th>
            <th>Location</th>
            <th>Actions</th>
        </tr>
    </thead>
    <tbody>
    <% @board2.each do |board| %>
        <tr>
        <td> <%=board.name %></td>
        <td> <%=board.company_name %></td>
        <td> <%=board.status %></td>
        <td> <%=board.price %></td>
        <td> <%=board.screen_size %></td>
        <td> <%=board.viewership_count %></td>
        <td> <%=board.tpye %></td>
        <td> <%=board.location %></td>

        <%= button_to "Delete", showboard_path(board.id) , method: :delete,form: { data: {confirm: "Are you sure?" } } , class: "btn btn-danger btn-user" %></td>
        
        </tr>
            <%end%>
    </tbody>

showboard controller:

class ShowboardsController < ApplicationController
    
    def showboards
        @board = Board.all
        @user = Owner.find_by(id: session[:user_id])
        @board2 = Board.where(company_name: @user.company_name)
    end
    def edit
        @board = Board.find(params[:id])
    end
    def update
        
        @board = Board.find(params[:id])
        if @board.update(board_params)
            redirect_to showboards_path
        else
            render edit    
        end    
    end
    def destroy
        @board = Board.find(params[:id])
        if @board.destroy
            flash[:notice] ="Board deleted successfully!"
            redirect_to showboards_path 
        end
    end    
    private
    
    def board_params
        params.permit(:name, :company_name, :screen_size, :location, :price, :tpye, :status, :viewership_count)
    end
    
end
