Tag function using acts-as-taggable-on on Devise My memo

gem installation

gem 'acts-as-taggable-on', '~> 6.0'
bundle install

Create table

$ rake acts_as_taggable_on_engine:install:migrations
$ rake db:migrate

Save tag Add the following to the model you want to tag. (This time I wanted to tag the Post model, so write it in post.rb) From the model folder

class Post < ApplicationRecord
  acts_as_taggable
end

Add the following with registration edit

  <div class="field">
    <%= f.label :tag_list %><br />
    <%= f.text_field :tag_list, value: @user.tag_list.join(","), class:"form-control" %>
  </div>

If you want to separate them with spaces, create acts_as_taggable_on.rb in config / initializers / and write as follows.

ActsAsTaggableOn.delimiter = ' '

users show.html.erb should also be below

<% @user.tag_list.each do |tag| %>
  <span class="badge badge-primary mr-1 p-2"><%= tag %></span>
<% end %>

<% @post.tag_list.each do |tag| %>
  <span style="background-color: #e9e9e9; border-radius: 5px;"><%= tag %></span>
<% end %>

Do you have the following for application.controller?

devise_parameter_sanitizer.permit(:account_update, keys:[:tag_list])

Additional Information Obviously, there are various methods available.

find_related_skills Tasks related to the same tag are displayed Although it is not the taggings_count method, the number of times the corresponding tag has been used is displayed. tag_counts All tag data can be acquired And so on ..... there were more.

Please refer to the reference for how to use it.

If the tags are registered with the same name, they will have the same ID. Example: Even if you register with Rails and a separate task, the id will be the same
