Whether project config changes should be written to YAML files automatically.

If set to false, you can manually write out project config YAML files using the project-config/write command.

WARNING

If this is set to false, Craft won’t have a strong grasp of whether the YAML files or database contain the most relevant project config data, so there’s a chance that the Project Config utility will be a bit misleading.

__construct()

Constructor.

The default implementation does two things:

• Initializes the object with the given configuration $config.
• Call init().

If this method is overridden in a child class, it is recommended that

• the last parameter of the constructor is a configuration array, like $config here.
• call the parent implementation at the end of the constructor.

View source

Arguments

• $config (array) – Name-value pairs that will be used to initialize the object properties

applyConfigChanges()

Applies given changes to the project config.

View source

Arguments

• $configData (array)

4.0.0

Applies changes in external config to project config.

View source

Throws

• craft\errors\BusyResourceException
  if a lock could not be acquired
• craft\errors\StaleResourceException
  if the loaded project config is out-of-date

areChangesPending()

Returns whether a given path has pending changes that need to be applied to the loaded project config.

View source

Arguments

• $path (string, null) – A specific config path that should be checked for pending changes. If this is null, then true will be returned if there are any pending changes in external config.
• $force (boolean) – Whether to check for changes even if it doesn’t look like anything has changed since the last time ignorePendingChanges() has been called.

Returns

boolean

defer()

Since

3.1.13

Defers an event until all other project config changes have been processed.
