This article delves into the causes of the 'null value in column 'id' violates not-null constraint' error when using PostgreSQL with the Yii2 framework. Through a detailed case study, it explains how the database attempts to insert a null value into the 'id' column even when it is not explicitly included in the INSERT statement, leading to constraint violations. The core solutions involve using SERIAL data types or PostgreSQL 10+ IDENTITY columns to auto-generate primary key values, thereby preventing such errors. The article provides comprehensive code examples and best practices to help developers understand and resolve similar issues effectively.
