How to to pass a parameter to update action?

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>

form_for([@company, @user]) should pass the company id. Are you setting @company in the edit action? — j-dexx
Might want to look at user_params... Test it by printing it to see if company_id is there. If it's not, might not be permitted by strong params — Mingsheng
all promblem in users_divisions table after update action column company_id will be null — adyl

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
