[RUBY] [Rails] I made a draft function using enum

Introduction

When I thought about making a draft function, there weren't many articles, so I decided to keep a record.

Development environment

ubuntu(WSL)
Ruby 2,5.1
Rails 6.0.2

Advance preparation

The following functions are assumed to have been created.

--Post function / details / delete / edit (Post) --Create / Details of User (User)

models/post.rb


  belongs_to :user

models/user.rb


  has_many :microposts, dependent: :destroy

Add a column to the Post table

First, add a status column to the Post model to make it a boolean type. It is possible to use interger instead of boolean. Enter the following command.

bin/rails g migration AddStatusToPost status:boolean

Edit the migration file.

migrationfile.rb


  def change
    add_column :microposts, :status, :boolean, default: true, null: false
  end

After editing, migrate.

Add enum to Post model.

models/post.rb


  enum status: { draft: false, published: true }

Specify the draft of the status column as false and the published of the status column as true.

Get information for each user

Get the id of user with @ user.

users_controller.rb


  #For draft
  def confirm
    @user = User.find(params[:user_id])
    @microposts = @user.microposts.draft.page(params[:page])
  end

  #For publication
  def show
    @user = User.find(params[:id])
    @microposts = @user.microposts.published.page(params[:page])
  end

Add routing

If you add collection, the URL will not have an id.

routes.rb


resources :users do
  get 'confirm'
end

View settings

I have extracted only the relevant parts.

view/users/show.html.slim


//User details screen
= link_to "Post list", @user
= link_to  "favorite", user_likes_path(current_user)
= link_to "Draft list", user_confirm_path(current_user)

//View my post
- if @microposts.present?
  = render "microposts/list", microposts: @microposts
- else
h4 No posts

Please write the draft list according to your preference.

view/users/confirm.html.slim


h4 draft list

table.table.table-hover
  thead.thead-default
    tr
      th = Micropost.human_attribute_name(:title)
      th = Micropost.human_attribute_name(:content)
      th = Micropost.human_attribute_name(:created_at)
      th
  tbody
    - @microposts.each do |micropost|
      tr
        td = link_to micropost.title, micropost
        td = link_to micropost.content, micropost
        td

The contents of ╩╗icroposts / list` are the same as above.

At the end

If you make a mistake, please make an edit request or comment.
