Using hstore and saving new values for user - ruby-on-rails-4

Question

My user model contains values for things like:
name, email, phone, approved, etc..
The scope of the project I am working on includes custom user settings and for this reason I am using hstore (I dont want to create a user_settings table).
On the user edit view I want to create a checkbox called 'colors' and whether or not the checkbox is checked determines if that setting is set for the user or not.
I have already setup hstore as follows:
class AddHstore < ActiveRecord::Migration
def up
enable_extension :hstore
end
def down
disable_extension :hstore
end
end
And updated the User model as follows:
class AddSettingsToUser < ActiveRecord::Migration
def up
add_column :users, :settings, :hstore
end
def down
remove_column :users, :settings
end
end
This is essentially my user edit view:
<%= form_for(resource, as: resource_name, url: registration_path(resource_name), html: { method: :put, :class => "form-horizontal user" }) do |f| %>
<%= devise_error_messages! %>
<div class="field">
<%= f.label :name %><br />
<%= f.text_field :name, autofocus: true %>
</div>
<div class="field">
<%= f.label :email %><br />
<%= f.email_field :email %>
</div>
<div class="field">
<%= f.label :phone_number %><br />
<%= f.text_field :phone_number %>
</div>
<div class="actions">
<%= f.submit 'Update', :class => 'btn btn-primary' %>
</div>
<% end %>
At this point I am unsure as to how to actually implement this functionality. The user edit page allows the user to change their name, phone and other values but how would I include a new value for the hstore settings?

Answer 1

Inside the form_for from where you are creating users, add your hstore fileds like below :
<%= form_for resource, ...do |f| %>
#...
<%= f.fields_for :settings do |settings| %>
<%= settings.text_field :field1 %>
<%= settings.text_field :field2 %>
<% end %>
#....
<% end %>
Then update your controller strong parameter method like below to permit these new fields.:
def user_params
params.require(:user)
.permit(
:name,
:email,
settings: [ :field1, :field2 ]
)
end
Now, you are done. Open your rails console and try some sample data like
User.create(
settings: { field1: 'data1', field2: 'data2' }
)
