Options

:meta_options

A list of generator options which only serve to trigger other options. These options should have no other effects, and will be treated transparently when revoking other options.

For example: –minimal implies both –skip-active-job and –skip-active-storage. Also, –skip-active-job by itself implies –skip-active-storage. If –skip-active-job is explicitly specified, –no-skip-active-storage should raise an error. But, if only –minimal is specified, –no-skip-active-storage should “undo” the implied –skip-active-job. This can be accomplished by passing meta_options: [:minimal].

In contrast, –api is not a meta option because it does other things besides implying options such as –skip-asset-pipeline. (And so –api with –no-skip-asset-pipeline should raise an error.)
