PATCH
PATCH is an HTTP request method for applying partial modifications to a resource.
Django in Action
PATCH is an HTTP method that requests partial modification of a resource using only changed fields.
- How it is used
- Uses PATCH to partially update REST resources when clients send only changed fields.
- How deep it goes
- Walks through Django Ninja’s schema requirement and field-by-field save flow, while deferring a complete PATCH listing.
- Examples
- Contrasts full-object PUT with changed-field PATCH for venue updates, SPAs, mobile clients, and attachment-heavy models.
- What you can do after
- Apply it via Django Ninja by defining an optional-field schema and updating only submitted model fields.
.NET in Action, Second Edition
PATCH is an HTTP method conventionally used to apply a partial update to a resource.
- How it is used
- Uses PATCH for resource updates when callers should submit only the fields they want to change.
- How deep it goes
- Works through lookup, conditional field assignment, persistence, status codes, and an alternative response, but not PATCH document formats.
- Examples
- Demonstrates partially updating a Book through nullable Title and Description command fields.
- What you can do after
- Apply partial updates through a C# controller while handling missing entities and asynchronous database persistence.
The Design of Web APIs, Second Edition
PATCH is the HTTP method for applying partial modifications to an existing resource.
- How it is used
- Maps update actions to requests that modify only selected properties of an existing resource.
- How deep it goes
- Explains request models, efficiency, formats, replay risks, and compatibility, but defers detailed implementation behavior.
- Examples
- Uses product price and description changes, transaction checking, optional modification schemas, and PATCH endpoint removal.
- What you can do after
- Operate/configure PATCH endpoints with partial schemas, suitable payloads, replay precautions, and compatible method changes.
