 rails g scaffold City name:string country:references
 </code>
+==== Multiple References ====
+To create multiple references to another model (for different attribute fields):
+<code>
+# The other model
+rails g Country name
+# In the scaffold command
+rails g scaffold Staff residing_country:references
+# In the migration
+t.references :residing_country, null: false, foreign_key: { to_table: :countries }
+# In the model
+belongs_to :residing_country, class_name: 'Country', foreign_key: 'residing_country_id'
+</code>
+==== Resetting the Database ====
+<code>
+rm storage/development.sqlite db/schema.rb
+rails db:drop db:create db:migrate
+</code>
+==== Turbo Frames ====
+Turbo frames are for partial view updates. When the view is being rendered, return content within the turbo frame tag with the same identifier. domid(model_object) can be used to generate an identifier.
+<code>
+# In home/index view
+<%= turbo_frame_tag "str_1" do %>
+This is a thing
+<%= link_to 'Action', controller: 'home', action: 'info'
+<% end %>
+# In home/info view
+<%= turbo_frame_tag "str_1" do %>
+This is another thing
+<%= link_to 'Action', controller: 'home', action: 'index'
+<% end %>
+</code>
+==== Turbo Streams ====
+<code>
+# In the view
+<%= turbo_stream_from "src_1" %>
+<div id="divvy_1"></div>
+# In a controller
+Turbo::StreamsChannel.broadcast_update_to(
+  'src_1',
+  target: 'divvy_1',
+  content: DateTime.now  # html: render ...
+)
