Fantastic, Rafe! Thanks so much!

Posted in How to use Hotwire in Rails Discussion

Can someone help me? I'm confused about Hotwire and some of the latest stuff that came out.

1) What is exactly Hotwire does?
2) And how can be it compared to StimulusJS, Stimulus Reflex and Actioncable?

I'm just having dificulties to understand what each of those are and how each can be used.

Thanks in advance.

Nice, @eelcoj and @Ali Ahmed. Thanks for sharing.

To anyone looking for more info about how to work with associated models, here is:

Item.rb (model):

  # Relations
  belongs_to :brand

    ## many-to-many relations between Items and Textures
    has_many   :item_attribute_for_textures
    has_many   :textures, through: :item_attribute_for_textures, :class_name => 'ItemAttribute::Texture'


    # Searchkick
  searchkick

  def search_data
    {
      full_item_title:  full_item_title,
      brand:            brand.try(:title),
      texture:          textures.map(&:title)
    }
  end   

ItemController.rb:

  def index
    args = {}
    args[:brand]          = params[:brand]          if params[:brand].present?
    args[:texture]        = params[:texture]        if params[:texture].present?

    query = params[:busca].presence || "*"
    @items  = Item.search query, where: args, 
      aggs: { 
          full_item_title:  {},
          brand:            {},
          texture:          {}
          }
  end

and view index.html.erb:

<div class="row">
  <div class="col-sm-2" style="font-size: 0.75rem">

    <h5>Brands</h5>
    <div>
      <% @items.aggs["brand"]["buckets"].sort_by{ |b| b["key"] }.each do |bucket| %>
        <div>
          <% if params[:brand] == bucket["key"].to_s %>
            <strong><%= bucket["key"] %></strong>
          <% else %>
            <%= link_to bucket["key"], request.params.merge(brand: bucket["key"]) %>
          <% end %>
          (<%= bucket["doc_count"] %>)
        </div>
      <% end %>
    </div>
    <hr>

    <h5>Texture</h5>
    <div>
      <% @items.aggs["texture"]["buckets"].sort_by{ |b| b["key"] }.each do |bucket| %>
        <div>
          <% if params[:texture] == bucket["key"].to_s %>
            <strong><%= bucket["key"] %></strong>
          <% else %>
            <%= link_to bucket["key"], request.params.merge(texture: bucket["key"]) %>
          <% end %>
          (<%= bucket["doc_count"] %>)
        </div>
      <% end %>
    </div>
    <hr>

  </div>
</div>

Be careful: you shouldn't allow any origin ("*") in your config CORs.

Posted in DataTables Install via Webpacker

Hi, Dan. Still in trouble? I managed to get a demo app running data-tables e others jquery library here: https://github.com/lucaszmoraes/Demo-Datatables-with-jQuery-Notifications

This demo is running Rails 6 with Webpack and Yarn.

According to the error that you describred at Datatables forum, looks like that you're missing to declare the jquery global variable '$'. Take a look to my environment configs (environment.js, app.js, etc) at the repo above.

Hi, Bozazitz! Thanks for the help out!

Fantastic, Chris! Thanks!

Hi, all.

We has an app with Rails 4.2.5 and Angular 2 integrated (we do not use it very much). But we would like to switch to another JS framework: Vue and Reacth are good options.

But will we have any conflicts since there will be two JS framework working?
