Search form don't update table in RoR - ruby-on-rails

Question

I'm trying to write a filter for the table. Here is the code:
.../models/message.rb
Class Message < ActiveRecord::Base
include Filterable
belongs_to :user
default_scope -> { order('created_at DESC') }
validates :user_id, presence: true
validates :content, presence: { message: "Выберите файл послания для загрузки!" }, file_size: { less_than_or_equal_to: 20.megabytes }
validates :fromdate, presence: true
validates :tilldate, presence: true
mount_uploader :content, ContentUploader
scope :id, -> (id) {where id: id }
scope :tariff, -> (tariff) { where tariff: tariff }
scope :status, -> (status) { where("status like ?", "#{status}%")}
end
.../controllers/concerns/filterable.rb
module Filterable
extend ActiveSupport::Concern
module ClassMethods
def filter(filtering_params)
results = self.where(nil)
filtering_params.each do |key, value|
results = results.public_send(key, value) if value.present?
end
results
end
end
end
.../controllers/messages_controller.rb
...
def index
#messages = Message.filter(params.slice(:id, :tariff, :status)).paginate(page: params[:page], :per_page => 10)
end
...
.../views/messages/index.html.erb
...
<table class="table table-bordered">
<thead>
<tr>
<th>Клиент</th>
<th>№</th>
<th>Дата</th>
<th>Послание</th>
<th>Тариф</th>
<th>Показ с</th>
<th>до</th>
<th>Стоимость, р.</th>
<th>Статус</th>
<% if current_user.admin? %>
<th>Модератор</th>
<% end %>
</tr>
</thead>
<tbody>
<tr>
<%= form_tag messages_path, method: "get" do %>
<td><%= text_field_tag "client" %></td>
<td><%= text_field_tag "id", nil, size: 1 %></td>
<td></td>
<td><%= submit_tag "Выбрать" %><br><br><%= button_tag "Очистить" %></td>
<td><%= select_tag "tariff", options_for_select(["", "1. Вечер", "2. Весь день", "1001. ВЕЧЕР БЕСПЛАТНО", "1002. ДЕНЬ БЕСПЛАТНО"]), {} %></td>
<td></td>
<td></td>
<td></td>
<td><%= select_tag "status", options_for_select(["", "В обработке", "Исполняется", "Отклонена", "Выполнена"]), {} %></td>
<td></td>
<% end %>
</tr>
<%= render #messages %>
</tbody>
</table>
</div>
...
.../views/messages/_message.html.erb
...
<% case message.status
when "В обработке"
#messagecolor="warning"
when "Исполняется"
#messagecolor="success"
when "Выполнена"
#messagecolor="info"
when /Отклонена.*/
#messagecolor="danger"
end
unless message.moderator.nil?
#moderator = User.find(message.moderator).name
end
%>
<tr class=<%= #messagecolor %> data-message_id="<%= message.id %>">
<% if current_user.admin? || current_user.role == "Модератор" %>
<td><%= message.user.name %></td>
<% end %>
<td><%= message.id %></td>
<td><%= message.created_at.strftime("%d/%m/%Y %T %z") %></td>
<td><img src="<%= message.content_url(:thumb) %>" data-toggle="modal" data-target="#myModal" data-content="<%= message.content_url%>"></td>
<td><%= message.tariff %></td>
<td><%= message.fromdate.strftime("%d/%m/%Y") %></td>
<td><%= message.tilldate.strftime("%d/%m/%Y") %></td>
<td><%= message.cost %></td>
<td class="status">
<%= message.status %>
<% if (current_user.admin? || current_user.role == "Модератор") && message.status == "В обработке" %>
<br>
<div class="btn-group">
<button type="button" class="btn btn-success" data-status="Исполняется" data-message_id="<%= message.id %>">Принять</button>
<button type="button" class="btn btn-danger" data-status="Отклонена" data-message_id="<%= message.id %>">Отклонить</button>
</div>
<% end %>
<% if (current_user.admin? || current_user.role == "Модератор") && message.status == "Исполняется" %>
<br>
<%= link_to "Изменить", edit_message_path(message.id), :class => "btn btn-info" %>
<% end %>
</td>
<% if current_user.admin? %>
<td class="moderator">
<%= #moderator %><br>
<%= message.updated_at.strftime("%d/%m/%Y %T %z")%>
</td>
<% end %>
</tr>
...
The filter only works after the page is refreshed. It is worth to get back to the page through the menu - the form button does not work, update by F5 - it works. Why?
I will also be grateful if you tell me how to save the selected filter values ​​in the fields after it is applied.

Answer 1

I found the answer to my main question: it need to include the entire table into the form in .../views/messages/index.html.erb
...
<%= form_tag messages_path, method: "get" do %>
<table class="table table-bordered">
<thead>
<tr>
<th>Клиент</th>
<th>№</th>
<th>Дата</th>
<th>Послание</th>
<th>Тариф</th>
<th>Показ с</th>
<th>до</th>
<th>Стоимость, р.</th>
<th>Статус</th>
<% if current_user.admin? %>
<th>Модератор</th>
<% end %>
</tr>
</thead>
<tbody>
<tr>
<td><%= text_field_tag "client" %></td>
<td><%= text_field_tag "id", nil, size: 1 %></td>
<td></td>
<td><%= submit_tag "Выбрать" %><br><br><%= button_tag "Очистить" %></td>
<td><%= select_tag "tariff", options_for_select(["", "1. Вечер", "2. Весь день", "1001. ВЕЧЕР БЕСПЛАТНО", "1002. ДЕНЬ БЕСПЛАТНО"]), {} %></td>
<td></td>
<td></td>
<td></td>
<td><%= select_tag "status", options_for_select(["", "В обработке", "Исполняется", "Отклонена", "Выполнена"]), {} %></td>
<td></td>
</tr>
<%= render #messages %>
</tbody>
</table>
<% end %>
</div>
...
And now it works correctly.
