rails' activerecord stores data into wrong table

Question

I have following model

# app/models/admin/furniture/wood/type.rb

class Admin::Furniture::Wood::Type < ApplicationRecord
  validates_presence_of :name
  validates_uniqueness_of :name
end

but when I'am trying to save the model, it stores into the wrong table!! only this model is wrong all other models are working ok.

I don't understand what is the problem, I checked everything model's path, even specified the table name with self.table_name nothing worked!! Why??

Edit:

The migration file:

# db/migrate/20170505064612_create_admin_furniture_wood_types.rb

class CreateAdminFurnitureWoodTypes < ActiveRecord::Migration[5.0]
  def change
    create_table :admin_furniture_wood_types do |t|
      t.string :name
      t.text :comment

      t.timestamps
    end
  end
end

Database config file:

# config/database.yml
# MySQL. Versions 5.0 and up are supported.
#
# Install the MySQL driver
#   gem install mysql2
#
# Ensure the MySQL gem is defined in your Gemfile
#   gem 'mysql2'
#
# And be sure to use new-style password hashing:
#   http://dev.mysql.com/doc/refman/5.7/en/old-client.html
#
default: &default
  adapter: mysql2
  encoding: utf8
  pool: 5
  username: root
  password: root
  socket: /var/run/mysqld/mysqld.sock
  variables:
    sql_mode: 'STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION'

development:
  <<: *default
  database: viramobl_development

# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
  <<: *default
  database: viramobl_test
  password: <%= ENV['TRAVIS'] ? '' : 'root' %>

# As with config/secrets.yml, you never want to store sensitive information,
# like your database password, in your source code. If your source code is
# ever seen by anyone, they now have access to your database.
#
# Instead, provide the password as a unix environment variable when you boot
# the app. Read http://guides.rubyonrails.org/configuring.html#configuring-a-database
# for a full rundown on how to provide these environment variables in a
# production deployment.
#
# On Heroku and other platform providers, you may have a full connection URL
# available as an environment variable. For example:
#
#   DATABASE_URL="mysql2://myuser:mypass@localhost/somedatabase"
#
# You can use this database configuration with:
#
#   production:
#     url: <%= ENV['DATABASE_URL'] %>
#
production:
  <<: *default
  database: viramobl_production
  username: viramobl
  password: <%= ENV['VIRAMOBL_DATABASE_PASSWORD'] %>
