- The only string works much the same as before with its comma separation -- Nested includes are indicated with square brackets "[ ]" -- The nested include is the value immediately preceding the square brackets -- The only string is the comma separated string inside those brackets - Default includes are split between format types when necessary -- This prevents unnecessary includes from being added on page load - Available includes are those items which are allowed to be accessible to the user -- Some aren't because they are sensitive, such as the creator of a flag -- Some aren't because the number of associated items is too large - The amount of times the same model can be included to prevent recursions -- One exception is the root model may include the same model once --- e.g. the user model can include the inviter which is also the user model -- Another exception is if the include is a has_many association --- e.g. artist urls can include the artist, and then artist urls again
