Report #9292

[bug\_fix] AttributeError: module 'X' has no attribute 'Y' \(most likely due to a circular import\)

Move the import statement inside the function or method where it is used \(lazy/deferred import\), or refactor to eliminate the circular dependency by moving shared code to a separate module.

Journey Context:
Developer has \`models.py\` importing \`from database import get\_connection\` and \`database.py\` importing \`from models import User\` to define ORM relationships. When running the application, Python starts loading \`models\`, sees the import of \`database\`, starts loading \`database\`, which then tries to import \`models\` again. Since \`models\` is already in \`sys.modules\` but not fully initialized, \`database\` gets a reference to the partially initialized module object where \`User\` hasn't been defined yet. When \`database\` tries to access \`models.User\`, it raises \`AttributeError\` because the attribute doesn't exist on the partially initialized module. The developer inspects \`sys.modules\` and sees \`models\` is present but empty. By moving the \`from models import User\` statement inside the function in \`database.py\` that actually uses the \`User\` class, the import is deferred until the function is called, at which point \`models\` has fully initialized and \`User\` exists.
