No implicit conversion of Symbol into Integer. A error still no solution for me

Question

I have a view with checkboxes and input text. I checked one checkbox and digit value on input, after submit. But have two problem... A error on params and don't save the values on my table, this is my code:

refinancings_controller.rb

 def new
    if params[:authorization]
      @selected_ids = params[:authorization][:contract_ids]
      @authorizations = Authorization.where("contract_number in (?)", @selected_ids)
    end
    @employee = Employee.search_cpf(params[:search_employee_by_cpf])
    @refinancing = Refinancing.new
    Authorization.where(id: params[:authorization][:contract_ids]).update_all(value_solve: params[:authorization][:value_solve], situation: 2)
  end

My console this is:

Processing by RefinancingsController#new as HTML
  Parameters: {"utf8"=>"✓", "search_employee_by_cpf"=>"11111111111", "authorization"=>{"value_solve"=>["", "3444555", ""], "contract_ids"=>["33"]}, "commit"=>"Reserve"}
Completed 500 Internal Server Error in 11ms (ActiveRecord: 0.3ms)

TypeError (no implicit conversion of Symbol into Integer):
  app/controllers/refinancings_controller.rb:37:in `[]'
  app/controllers/refinancings_controller.rb:37:in `new'

This is a first error:

no implicit conversion of Symbol into Integer

The other error is don't show params situation...

Answer 1

Rails passes the keys of the params hash as strings not symbols, as you can see in the stack trace that you've provided.

Parameters: {"utf8"=>"✓", "search_employee_by_cpf"=>"11111111111", "authorization"=>{"value_solve"=>["", "3444555", ""], "contract_ids"=>["33"]}, "commit"=>"Reserve"}

Change your code to use strings e.g.

if params["authorization"]
  @selected_ids = params["authorization"]["contract_ids"]

etc.

Answer 2

def new
    if params[:authorization].present?
      @selected_ids = params[:authorization][:contract_ids]
      @authorizations = Authorization.where("contract_number in (?)", @selected_ids)
      Authorization.where(id: params[:authorization][:contract_ids]).update_all(value_solve: params[:authorization][:value_solve], situation: 2)
    end
    @employee = Employee.search_cpf(params[:search_employee_by_cpf])
    @refinancing = Refinancing.new
  end

Try this

Answer 3

With this code:

  def new
    if params[:authorization].present?
      @selected_ids = params[:authorization][:contract_ids]
      @authorizations = Authorization.where("contract_number in (?)", @selected_ids)
      Authorization.where(id: params[:authorization][:contract_ids]).update_all(value_solve: params[:authorization][:value_solve], situation: 2)
    end
    @employee = Employee.search_cpf(params[:search_employee_by_cpf])
    @refinancing = Refinancing.new

Have no more errors, ok, but don't save in my table Authorization, because the id is get wrong. Look my console:

Started GET "/refinancings/new?utf8=%E2%9C%93&search_employee_by_cpf=02849112321&authorization%5Bcontract_ids%5D%5B%5D=11&authorization%5Bvalue_solve%5D%5B%5D=89888&authorization%5Bvalue_solve%5D%5B%5D=&authorization%5Bvalue_solve%5D%5B%5D=&commit=Reserve" for 127.0.0.1 at 2016-04-18 10:40:08 -0300

The "authorizations"."id" = 11, but I don't have id 11 for authorizations, was to be id 1. What I do? Please : (

UPDATED --------------------------------

This is my view index.html.erb. I marked the checkboxes and digit some value on input value_solve and click in Reserve

<% if params[:search_employee_by_cpf].present? %>
  <h4><b>Results</b></h4>
  <%= form_tag(new_refinancing_path, name: 'form', method: :get) do %>
    <%= hidden_field_tag 'search_employee_by_cpf', params[:search_employee_by_cpf] %>
    <% @employees.each do |employee| %>
      <table class="table table-condensed">
        <tr>
          <th>Name</th>
          <td><%= employee.person.name %></td>
        </tr>
        <tr>
          <th>Register</th>
          <td><%= employee.register %></td>
        </tr>
        <tr>
          <th>CPF</th>
          <td><%= employee.person.cpf %></td>
        </tr>
      </table>

      <hr />

      <table class="table table-condensed table-bordered table-hover">
        <thead>
          <th>&nbsp;</th>
          <th>Contract number</th>
          <th>Total Value</th>
          <th>Value to Solve</th>
        </thead>
        <tbody>
          <% employee.authorizations.each do |authorization| %>
            <tr>
              <td><%= check_box_tag 'authorization[contract_ids][]', authorization.contract_number %></td>
              <td><%= authorization.contract_number %></td>
              <td><%= authorization.total_value %></td>
              <td>
                <input class="string required" placeholder="Digit a value" type="text" name="authorization[value_solve][]" id="authorization_value_solve">
              </td>
            </tr>
          <% end %>
        </tbody>
      </table>

    <% end %>

    <%= submit_tag "Reserve %>

  <% end %>
<% end %>

The controller for form index is simple and work, just this:

  def index
    if params[:search_employee_by_cpf].present?
      @employees = Employee.search_cpf(params[:search_employee_by_cpf]).includes(:authorizations)
Authorization.search_employee_by_cpf(params[:search_employee_by_cpf]).all
    else
      @authorizations = []
    end
  end

After click in Reserve, with the checkboxes checked and value digited my console is this, how I said:

Started GET "/refinancings/new?utf8=%E2%9C%93&search_employee_by_cpf=02849112321&authorization%5Bcontract_ids%5D%5B%5D=11&authorization%5Bvalue_solve%5D%5B%5D=777777&authorization%5Bvalue_solve%5D%5B%5D=&authorization%5Bvalue_solve%5D%5B%5D=&commit=Reserve" for 127.0.0.1 at 2016-04-18 16:08:37 -0300

  SQL (0.2ms)  UPDATE "authorizations" SET "value_solve" = '---
- ''777777''

- ''''
', "situation" = 2 WHERE "authorizations"."id" = 11

Answer 4

The answer this is:

      auth_params = params[:authorization]
auth_params[:contract_number].zip(auth_params[:value_solve].reject(&:blank?)).each do |contract_number, value_solve|
          Authorization.where(contract_number: contract_number).update_all(value_solve: value_solve, situation: 2)
      end
