Bulletins and Boards

my Rails Portfolio Project

welcome to my rails portfolio project summary, the concept is to build an online bulletin board. bulletin board is a surface(board) intended for the posting of public messages, for example, to advertise items wanted or for sale, announce events, or provide information.

After creating crud actions for class model Board and Bulletin and created a Users sign up and Log in, my first question is how can I associate Users and Boards and how can I add Bulletins into the Board??

looking at my association: Board belongs_to :user and User has_many :boards

Board has_many users, through: :bulletins & User has_many :boards, through: :bulletins

connecting user and boards

in my application controller I define a method called current_user this method will allow me to build associations with the user upon creation of a new object.

app/controllers/applicationcotrller.rb

def current_user
      @current_user ||= User.find_by_id(session[:user_id]) if session[:user_id]
 end

Now in my board controller; I use the build method to create boards that is associated with the current_user.

app/controllers/ boards_controller.rb

    def create 
      @board = 
      @board = current_user.boards.build(board_params)

      if @board.save 
        redirect_to board_path(@board)
      else 
        render :new 
      end
    end

Now ist time add bulletins to the board

in my association, boards has_many :bulletins and bulletins belongs_to : board

now I can say that Board is a parent of Bulletin. I can create a nested routes.

and a link_to for more easier navigation in my application

config/routes

resources :boards do 
    resources :bulletins, shallow: true 
  end   

board index.html.erb

<p> <%= link_to "Create New Bulletins", new_board_bulletin_path(board)%> </p>

the code below tells us: ` if board is nested look for board_id in the params else` create a new bulletins associated with the current_user.

and add board_id to bulletin_params

app/controllers/bulletincontroller.rb

def new                                                
      if @board = Board.find_by_id(params[:board_id]) if params[:board_id]                             
         @bulletin = @board.bulletins.build 
      else 
        #flash[:message] = "Board does not exist!"
        @bulletin = current_user.bulletins.build 
      end
  end  

def bulletin_params 
      params.require(:bulletin).permit(:title, :content, :rating, :board_id) 
end 

Views

view/bulletins/new.html.erb

Header for my new form to support the conditional in my new action

if nested create nested bulletins for this board else create unnested bulletins

   <%  if board %>
     <%=  "New Bulletins for #{board.title}" %>
   <% else %>
      <%= "New Bulletin" %>
     <% end %>

<%= form_for ([@board, @bulletin]) do |f| %>

  <% if !@bulletin.board %> 
	
  <%= f.label :board %>
  <%= f.collection_select :board_id, Board.all, :id, :title %>
	
  <% else %>
  <%= f.hidden_field :board_id %> 
   <% end %>

  <%= f.label :title %>
  <%= f.text_field :title %>
  <%= f.label :content %>
  <%= f.text_field :content %> 
  <%= f.submit %>
<% end %>

Setting up my associations and connecting all my models together is the most challenging part of my rails project. now I can start adding validations and additional features in my application.
