How to save additional informations from Devise form? - ruby-on-rails

Question

I have a application controller like this :
class ApplicationController < ActionController::Base
before_action :configure_permitted_parameters, if: :devise_controller?
protected
def configure_permitted_parameters
devise_parameter_sanitizer.permit(:sign_up, keys: [:first_name, :last_name, :description, :city_id, :golf_level])
end
end
and a form sign up with device like this :
<h2 class='container'>Inscription</h2>
<div class="tab-pane show active" id="component-1-1" role="tabpanel" aria-labelledby="component-1-1">
<div class="component-example">
<div class='container'>
<%= form_for(resource, as: resource_name, url: registration_path(resource_name)) do |f| %>
<div class='row'>
<div class="col-md-6">
<%= render "devise/shared/error_messages", resource: resource %>
<div class='field form-group'>
<%= f.label 'Prénom' %><br>
<%= f.text_field :first_name, class: 'form-control' %>
</div>
<div class='field form-group'>
<%= f.label 'Nom' %><br>
<%= f.text_field :last_name, class: 'form-control' %>
</div>
<div class="field form-group">
<%= f.label :email %><br />
<%= f.email_field :email, autofocus: true, autocomplete: "email", class: 'form-control' %>
</div>
<div class='field form-group'>
<%= f.label 'Niveau' %>
<%= select_tag(:golf_level, options_for_select([['débutant', 'débutant'], ['intermediaire', 'intermediaire'], ['confirmer', 'confirmer']])) %>
</div>
</div>
<div class="col-md-6">
<div class="field form-group">
<%= f.label 'Mot de passe' %>
<% if #minimum_password_length %>
<em>(<%= #minimum_password_length %> characters minimum)</em>
<% end %><br />
<%= f.password_field :password, autocomplete: "new-password", class: 'form-control' %>
</div>
<div class="field form-group">
<%= f.label 'Confirmer mot de passe' %><br />
<%= f.password_field :password_confirmation, autocomplete: "new-password", class: 'form-control' %>
</div>
<div class='field form-group'>
<%= f.label 'Ville' %>
<%= select_tag(:city_id, options_for_select( City.all.collect { |city| [city.name, city.id] }, {target_blank: true} )) %>
</div>
<div class='field form-group'>
<%= f.label 'Description'%>
<%= f.text_area :description, size: "60x5", class: 'form-control'%>
</div>
</div>
<div class="actions">
<%= f.submit "Inscription", class: 'btn btn-primary' %>
</div>
<% end %>
<button class='btn btn-primary' style="margin-left:20px;"><%= render "devise/shared/links" %></button>
</div>
</div>
</div>
</div>
My problem is maybe stupid but : When i create a User with this form the selects tags golf_level and city_id are not save in db but all other yes. In device doc I don't find special way for select form.

Ok, your parameters are passed, but not within proper namespace. Instead of select_tag you should use f.select method:
<%= f.select(:city_id, options_for_select(City.pluck(:name, :id), target_blank: true )) %>
And likewise for the second of your params.
