How to to pass a parameter to update action? - ruby-on-rails

Question

In my app users has many companies, and companies has many users, companies has many divisions and users have different division in different company for example User with id 1 belongs to Company 1 and Division 2 and to Company 2 Division 3
User.rb
class User < ActiveRecord::Base
has_many :companies, through: :users_companies
has_many :users_companies
has_many :divisions, through: :users_divisions
has_many :users_divisions
has_many :users_roles, dependent: :destroy
has_many :roles, through: :users_roles
end
Company.rb
class Company < ActiveRecord::Base
#before_create :create_division
has_many :users_companies
has_many :users, through: :users_companies
has_many :divisions, dependent: :destroy
has_many :positions
end
Division.rb
class Division < ActiveRecord::Base
has_ancestry
belongs_to :company
has_many :users, through: :users_divisions
has_many :users_divisions
end
UsersCompany.rb
class UsersCompany < ActiveRecord::Base
belongs_to :user
belongs_to :company
end
UsersDivision.rb
class UsersDivision < ActiveRecord::Base
belongs_to :user
belongs_to :division
belongs_to :company
end
UsersDivision table have structure
id|user_id|division_id|company_id
when create all be fine
UsersDivision.create!(user: #user, division_id: params[:user][:division_ids], company_id: #company.id)
but when I try to update #user in table UsersDivision column company_id will be nill.
def update
#company = Company.find(params[:company_id])
#user = User.find(params[:id])
if #user.update(user_params)
redirect_to :back
end
end
How to pass params :company_id to update action?
<div class="edit-registration-container">
<%= #user.full_name %>
<%= form_for([#company, #user]) do |f| %>
<%= f.label :last_name, "Фамилия" %><br />
<%= f.text_field :last_name, type: "text" %>
<%= f.label :first_name, "Имя" %><br />
<%= f.text_field :first_name, type: "text" %>
<%= f.label :middle_name, "Отчество" %><br />
<%= f.text_field :middle_name, type: "text" %>
<%= f.label :division_ids, "Подразделение" %><br />
<%= f.select :division_ids, #divisions_select %><br />
<%= f.hidden_field :company_id, value: #company.id %>
<%= f.fields_for :positions, #position do |ff| %>
<%= ff.label :name, "Должность" %>
<%= ff.text_field :name, type: "text" %>
<%= ff.hidden_field :company_id, value: #company.id %>
<% end %>
<%= hidden_field_tag "user[role_ids][]", nil %>
<% Role.all.each do |role| %>
<%= check_box_tag "user[role_ids][]", role.id, #user.role_ids.include?(role.id), id: dom_id(role) %>
<%= label_tag dom_id(role), role.name %><br>
<% end %>
<%= f.submit "Сохранить", class: "login loginmodal-submit", type: "submit" %>
<% end %>
</div>

You need to permit that parameter to be accessible, so add it in your
user controller params permit:
params.require(:user).permit(YOUR PARAMETERS, {:company_id => []})
Then you can call it using:
params["user"]["company_id"]
I think you can simply do this inside your update action:
#company = Company.find(params["user"]["company_id"])
Here is my working example form:
<%= form_for :user, :url => custom_users_path do |f| %>
<%= f.text_field :name %>
<%= f.hidden_field :company_id, :value => Company.find(1).id %> #4
<%= f.submit "Submit" %>
After I submit, inside my custom action my params["user"]["company_id"] would have this value: 4
