Class Method Details

.create_for_designs(design_actions, sha, author) ⇒ Object

This is the one true way to create a Version.

This method means you can avoid the paradox of versions being invalid without designs, and not being able to add designs without a saved version. Also this method inserts designs in bulk, rather than one by one.

Before calling this method, callers must guard against concurrent modification by obtaining the lock on the design repository. See: `DesignManagement::Version.with_lock`.

Parameters:

  • design_actions [DesignManagement::DesignAction]:

    the actions that have been performed in the repository.

  • sha [String]:

    the SHA of the commit that performed them

  • author [User]:

    the user who performed the commit

returns [DesignManagement::Version]
