fix: incorrect value type when using @default with boolean field from auth()

[ymc9]

fixes #2038

[coderabbitai]

📝 Walkthrough

Walkthrough

This pull request updates the schema generation process to handle Boolean default values correctly. The setDummyDefault method in the Prisma schema generator now assigns false as a Boolean rather than the string 'false'. Additionally, a new regression test (issue 2038) has been added to confirm that models using Boolean defaults are generated and processed accurately in the system.

Changes

File(s)	Change Summary
packages/schema/src/.../schema-generator.ts	Modified setDummyDefault to assign Boolean false (Boolean type) instead of 'false' (string) for Boolean fields in the generated schema.
tests/regression/tests/issue-2038.test.ts	Added a regression test for issue #2038 which loads a schema with Boolean fields and asserts that default values are correctly applied during creation.

1-26: Well-designed regression test for issue #2038

This test effectively verifies the fix for incorrect boolean type handling when using @default with auth(). It creates a clear scenario where a Post model has a published field defaulting to the value of auth().flag, and confirms the boolean value is correctly propagated.

896-896: Good fix for boolean type handling

This change fixes the core issue by ensuring that default values for Boolean fields are represented as actual Boolean types (false) rather than strings ('false'). This is essential for proper type handling when using @default(auth().flag) as demonstrated in the regression test.

The AttributeArgValue constructor expects the value's type to match the specified type parameter, and this change correctly aligns them.

• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
