Class methods

any?

Returns true if at least one of the collection's members is truthy.

[nil, true, 99].any? # => true
[nil, false].any?    # => false
([] of Int32).any?   # => false

#present? does not consider truthiness of elements.
#any?(&) and #any(pattern) allow custom conditions.

NOTE: #any? usually has the same semantics as #present?. They only differ if the element type can be falsey (i.e. T <= Nil || T <= Pointer || T <= Bool). It's typically advised to prefer #present? unless these specific truthiness semantics are required.

find(id) : T

first

Returns the first element in the collection. Raises Enumerable::EmptyError if the collection is empty.

([1, 2, 3]).first   # => 1
([] of Int32).first # raises Enumerable::EmptyError

first?

Returns the first element in the collection. When the collection is empty, returns nil.

([1, 2, 3]).first?   # => 1
([] of Int32).first? # => nil

last

last?

new_with_existing_query(query : Avram::QueryBuilder)

none?

Returns true if all of the elements of the collection are falsey.

[nil, false].none?       # => true
[nil, false, true].none? # => false

It's the opposite of all?.

truncate(*, cascade : Bool = false, restart_identity : Bool = false)

Removes all data from a table using the TRUNCATE postgres SQL command.

You should run this command with cascade: true if your table columns are referenced by other foreign key constraints. Use delete instead if you don't want to accidentally delete rows referenced elsewhere.

To delete all data referenced by foreign keys as well, set cascade to true.
