Method deprecated or moved

This method is deprecated or moved on the latest stable version. The last existing version (v7.0.0) is shown here.

These similar methods exist in v7.1.3.2:

strict_loading!(value = true, mode: :all) public

Sets the record to strict_loading mode. This will raise an error if the record tries to lazily load an association.

user = User.first
user.strict_loading! # => true
user.comments
=> ActiveRecord::StrictLoadingViolationError

Parameters:

value - Boolean specifying whether to enable or disable strict loading.

mode - Symbol specifying strict loading mode. Defaults to :all. Using

:n_plus_one_only mode will only raise an error if an association
that will lead to an n plus one query is lazily loaded.

Example:

user = User.first
user.strict_loading!(false) # => false
user.comments
=> #<ActiveRecord::Associations::CollectionProxy>
