Posted in Tailwind - own components - yes or no?

@Ricky thanks for this input. i already have started to use more Vue including components / slots.

Posted in Tailwind - own components - yes or no?

excellent explained - thanks a lot.

Posted in Tailwind - own components - yes or no?

i have started with tailwindcss yesterday the first time and must say - wow!

but something is confusing me from the beginning. in tutorials/videos etc. everybody talk about: do not write your own css-file, just put the whole styling into view-pages. but why - it is not DRY? for a style that is used one time (e.g. body bg-grey-100) or even a couple of times in layout templates etc. it makes sense to handle style in the views.

all the styles i am using throughout the entire app (such as buttons, links, cards etc.) i will "outsource" to the css-file (@apply).

  • reusable
  • cleaner code in views (better reading)
  • faster changes
  • DRY

i am on the right way with this? or is there another approach behind "no own css components"?

thanks for your thoughts - stay safe.

Posted in Group Chat with ActionCable: Part 7 Discussion

This serie is a masterpiece - learned much. As i am using Rails 6 i was struggling several times - and gave up for a while. There are big changes between Rails 5 and 6 and also ActionCable was getting improved. Some updates here after almost 4 years since creation would be very very helpful for all the Members who are starting a new Apps - they will do it for sure with Rails 6. Thanks in advance for any helps.

wow - great! i had a little typo there. now it works perfectly. thanks a lot for super fast help - cheers.

Thanks mate. I have tried a lot and have been at this point before - but it does not show anything on the index page. I want to show you some server-logs:

using code from above:

User Search (9.8ms)  users_development/_search {"aggs":{"first_name":{"filter":{"bool":{"must":[{"term":{"account_id":1}}]}},"aggs":{"first_name":{"terms":{"field":"first_name","size":1000}}}},"languages":{"filter":{"bool":{"must":[{"term":{"account_id":1}}]}},"aggs":{"languages":{"terms":{"field":"languages","size":1000}}}}},"query":{"bool":{"must":{"match_all":{}},"filter":[{"term":{"account_id":1}}]}},"timeout":"11s","_source":false,"size":10000}

this looks fine for account: :{"must":[{"term":{"account_id":1}}]} => exactly what i need, but no User Load and empty view.

Code without query:

User Search (5.0ms)  users_development/_search {"aggs":{"first_name":{"filter":{"bool":{"must":[{"term":{"account_id":1}}]}},"aggs":{"first_name":{"terms":{"field":"first_name","size":1000}}}},"languages":{"filter":{"bool":{"must":[{"term":{"account_id":1}}]}},"aggs":{"languages":{"terms":{"field":"languages","size":1000}}}}},"query":{"bool":{"must":{"match_all":{}},"filter":[{"term":{"account_id":1}}]}},"timeout":"11s","_source":false,"size":10000}

using query or not does the same thing, just in half of the time.

kicking out args[:account_id] =

User Search (4.7ms)  users_development/_search {"aggs":{"first_name":{"terms":{"field":"first_name","size":1000}},"languages":{"terms":{"field":"languages","size":1000}}},"query":{"match_all":{}},"timeout":"11s","_source":false,"size":10000}

 User Load (0.3ms)  SELECT "users".* FROM "users" WHERE "users"."id" IN ($1, $2, $3, $4, $5, $6, $7, $8, $9, $10)  [["id", 1], ["id", 2], ["id", 3], ["id", 4], ["id", 5], ["id", 6], ["id", 7], ["id", 8], ["id", 9], ["id", 10]]

shows all of the users from all accounts - this is not what i need or want, but it shows, that the setup and view is pretty close to ok, only the scope for Current.account does not filter out the users..

Reindex shows:

User Load (0.5ms) SELECT "users".* FROM "users" ORDER BY "users"."id" ASC LIMIT $1 [["LIMIT", 1000]]
Account Load (0.4ms) SELECT "accounts".* FROM "accounts" WHERE "accounts"."id" IN ($1, $2) [["id", 1], ["id", 2]]
Userlanguage Load (0.3ms) SELECT "userlanguages".* FROM "userlanguages" WHERE "userlanguages"."user_id" IN ($1, $2, $3, $4, $5, $6, $7, $8, $9, $10) [["user_id", 1], ["user_id", 2], ["user_id", 3], ["user_id", 4], ["user_id", 5], ["user_id", 6], ["user_id", 7], ["user_id", 8], ["user_id", 9], ["user_id", 10]]
Language Load (0.3ms) SELECT "languages".* FROM "languages" WHERE "languages"."id" IN ($1, $2) [["id", 1], ["id", 2]]
User Import (25.8ms) {"count":10}
=> true

Here i am not sure, if correct - User Load does not list anything?

@Chris, thanks for fast reply. I am working quite some time on this piece of code - and whatever i try, it does not work. Or in other words: i don't know how to follow your advise and put the stuff together. Some more help is needed, i guess.

My App uses Current.account from ActiveSupport and i need to show only Users (for filtering) who belongs to the Current.account.

The following Setup for Search Filters with Aggregations (searchkick) works so far. BUT:

  • it does show all User Records - not only Current.account.users
  • when i delete || "*" from the query in the controller i get nothing shown up

Means, i have a serious problem with this kind of "Top Level Scope".

# user.rb
  searchkick filterable: [:first_name, :languages, :account]

  has_many :user_languages
  has_many :languages, through: :user_languages
  belongs_to :account

    scope :search_import, -> { includes(:account, :languages) }

    def search_data
            account_id: Current.account,
            first_name: first_name,
# user_controller.rb
def index
    query = params[User.where(account_id: Current.account)]  || "*" 

    args = {}
    args[:first_name] = params[:first_name] if params[:first_name].present?
    args[:languages] = params[:languages] if params[:languages].present?
    @users = query, where: args,
                                aggs: {
                                  first_name: {},
                                  languages: {}
# users/index.html.erb
<div class="container">
  <div class="row">
    <div class="col-sm-3">
      <div><%= link_to "List All", users_path %></div><br>
      <h6>First Name</h6>
      <% @users.aggs["first_name"]["buckets"].each do |bucket| %>
          <% if params[:first_name] == bucket["key"].to_s %>
            <strong><%= link_to bucket["key"], request.params.except(:first_name) %></strong>
          <% else %>
            <%= link_to bucket["key"], request.params.merge(first_name: bucket["key"]) %>
          <% end %>

          (<%= bucket["doc_count"] %>)
      <% end %>

      <% @users.aggs["languages"]["buckets"].each do |bucket| %>
          <% if params[:languages] == bucket["key"].to_s %>
            <strong><%= link_to bucket["key"], request.params.except(:languages) %></strong>
          <% else %>
            <%= link_to bucket["key"], request.params.merge(languages: bucket["key"]) %>
          <% end %>

          (<%= bucket["doc_count"] %>)
      <% end %>
    <div class="col-sm-9">
      <%= render 'user_index' %>

Thanks a lot for a any clue or hint - Cheers.

i like this hack - thanks for sharing.

Posted in How Do I Use Selectize in Rails 6

Hi @Jeremy, the following implementation works well for me in Rails 6:

yarn add selectize


@import "selectize/dist/css/selectize";
@import "selectize/dist/css/selectize.default";



javascript/packs/language.js (code from video)

$(document).on("turbolinks:load", function() {
    var selectizeCallback = null;

    $(".language-modal").on("", function(e) {
        if (selectizeCallback != null) {
            selectizeCallback = null;


    $("#new_language").on("submit", function(e) {
            method: "POST",
            url: $(this).attr("action"),
            data: $(this).serialize(),
            success: function(response) {
                selectizeCallback({value:, text:});
                selectizeCallback = null;


        create: function(input, callback) {
            selectizeCallback = callback;


and finally the view on edit.html.erb

          <%= :language_ids, Language.all.pluck(:name, :id), {}, { multiple: true, class: "selectize" } %>

                    <div class="modal fade language-modal" tabindex="-1" role="dialog" aria-labelledby="mySmallModalLabel">
  <div class="modal-dialog modal-sm" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button>
        <h4 class="modal-title" id="mySmallModalLabel">Add Language</h4>
      <div class="modal-body">
        <%= form_for do |f| %>
          <div class="form-group">
            <%= f.label :name %>
            <%= f.text_field :name, class: "form-control" %>
          <div class="form-group">
            <%= f.submit class: "btn btn-primary" %>
        <% end %>

That's it - hope it helps. Cheers
