Day 67 - #100DaysofCode - Adding Categories to Rails App

sincerelybrittany profile image Brittany ・2 min read

I spent the day trying to add categories to my rails application. I am still in the process of adding some other functionality, like the nested route portion of it. However, so far, I was able to create a migration and make sure that post belong to a category and that a category can have many posts. In addition, I was able to create a drop down for each category on the posts index page.

Schema

categories

  create_table "categories", force: :cascade do |t|
    t.string "name"
    t.text "desc"
    t.datetime "created_at", precision: 6, null: false
    t.datetime "updated_at", precision: 6, null: false
  end

posts

create_table "posts", force: :cascade do |t|
    t.string "title"
    t.text "description"
    t.integer "user_id"
    t.integer "category_id"
  end

Models

post.rb

    #Categories section
    belongs_to :category

category.rb

class Category < ApplicationRecord
    has_many :posts
end

Views

<%= form_tag posts_path, method: :get do %>
  <p>
    <%= select_tag "category_id", options_from_collection_for_select(Category.all, "id", "name"), {:include_blank => 'Search By Category'} %>
    <%= submit_tag "Search", name: nil, :class => "myButton" %>
  </p>
<% end %>

Controller

Posts Controller

if @category = params[:category_id]
        @posts = Post.where(category_id: @category)
        render 'index'
      else
        @post = Post.all
        @categories = Category.all
      end
 end

I need to refactor my code so that Post.where(category_id: @category) is in my model, instead of my posts controller, but my categories functionality seems to be coming together. I will work on it more and share the final code in the near future.

As always, thanks for reading!

Sincerely,
Brittany
