I have column inviter in my User model. I want get params from the link and save it in cookies. For example, from this link:
domain.com/?ref=5
I want save to cookies number ?ref=**5**
And when a user goes to registration, the user will not need to write in the number of the referral in the form, because it is already in cookies.
<%= form_for(@user) do |f| %>
<%= render 'shared/error_messages', object: f.object %>
<%= f.label :name,'Your name'%>
<%= f.text_field :name, class: 'form-control' %>
<%= f.label :email,'Email' %>
<%= f.email_field :email, class: 'form-control' %>
<%= f.label :invite, 'Number who invited you' %>
<%= f.text_field :invite, class: 'form-control' %>
<%= f.label :password, 'password' %>
<%= f.password_field :password, class: 'form-control' %>
<%= f.label :password_confirmation ,'password confirmation' %>
<%= f.password_field :password_confirmation, class: 'form-control' %>
<br>
<br>
<div class="textc">
<%= f.submit yield(:button_text), class: "formbut" %>
</div>
<% end %>
The invite number will use ?ref=**5** and register the new user.
Add something like this to your application_controller.rb:
before_action :store_ref
private
def store_ref
cookies[:ref] = params[:ref] if params[:ref].present?
end
And something like this to your user create action:
def create
@user = User.new(user_params)
@user.ref = cookies[:ref]
if @user.save
# ...
