How to do wild card subdomains in rails 5

In Ryan Bates railscast on subdomains, he gives the following way to match subdomains

# config/routes.rb
match '', to: 'pro_users#show', contraints: lambda { |r| r.subdomain.present? && r.subdomain != 'www' }

but match without the HTTP verb was deprecated in rails 5, so this gives an exception

You should not use the `match` method in your router without specifying an HTTP method.

So how do you do this in rails 5 and above?

In rails 5, you have to specify which HTTP verb that you want to use. So in if you want to use that route for get and post, you would write

# config/routes.rb
    match '', to: 'pro_users#show', via: [:get,:post], contraints: lambda { |r| r.subdomain.present? && r.subdomain != 'www' }

You might also like to clean up the constraint by using a contraint class, this blog has some suggestions.

So you could write the route matcher as

# config/routes.rb
match '', to: 'pro_users#show', via: [:get,:post], contraints: SubdomainConstraint }

and

class SubdomainConstraint
   def self.matches?(request)
     request.subdomain.present? && request.subdomain != 'www'
  end
end
