Method: Issue#project=

Defined in:
app/models/issue.rb

#project=(project, keep_tracker = false) ⇒ Object

Sets the project. Unless keep_tracker argument is set to true, this will change the tracker to the first tracker of the new project if the previous tracker is not part of the new project trackers. This will:

  • clear the fixed_version is it’s no longer valid for the new project.

  • clear the parent issue if it’s no longer valid for the new project.

  • set the category to the category with the same name in the new project if it exists, or clear it if it doesn’t.

  • for new issue, set the fixed_version to the project default version if it’s a valid fixed_version.
