I am using eventbrite omniauth to authenticate the user. With reference to https://github.com/k504866430/omniauth-eventbrite I included the gem and created a file omniauth.rb file as:
Rails.application.config.middleware.use OmniAuth::Builder do
provider :eventbrite, ENV['EVENTBRITE_CLIENT_ID'], ENV['EVENTBRITE_CLIENT_SECRET']
end
On the show page of each event there is link to Authenticate with eventbrite.
events/24
= link_to "Authenticate with Eventbrite", "/auth/eventbrite"
When the user allows to access I want the callback url to redirect to same event page.
Thus I need to know how to pass the event_id in params so that the application can return to the same event page and how should the callback url be defined in routes.rb file
Eventbrite’s OAuth2.0 implementation does not allow you to define the OAuth callback URL as a querystring parameter. This callback_url can only be defined by configuring your Eventbrite application key‘s ‘redirect_uri’ setting.
Pass-through of custom querystring parameters (such as an event_id) is also not supported.
Besides, you’ll need to do a bit of follow-up work AFTER the user arrives back on your site.
If you need to redirect a user after they return to your website, I would consider stashing the ‘redirect_url’ (and possibly the event_id as well) in the user’s browser session or another data store.
Setting up a single landing page (to match your redirect_uri) should allow you to complete the OAuth2.0 handshake before sending the user on to a url of your choice.
