Go's Gorm database operation error WHERE conditions required

This is the problem I am writing this code

result := db.Save(&emergency)

This error is because GORM needs to specify the WHERE condition when submitting the saved data to ensure that the database operation can be performed correctly. To fix this, try using Createthe method substitution Savemethod while storing the result of the creation in a variable so you can check for errors.

In GORM, both Savemethods and Createmethods are used to save data to the database. Their main differences are:

save method

• usage:db.Save(&data)
• Function: Perform insert or update operations based on the provided data object (structure). If the provided object already exists in the database (based on primary key or unique index), an update operation will be performed; otherwise, an insert operation will be performed.
• If the data object contains primary key or unique index fields, GORM will use these fields to decide whether to perform an insert or update operation.
• After performing the save operation, Save the method returns an  *gorm.DB object whose  Error properties can be used to check whether an error occurred.

Create method

• usage:db.Create(&data)
• Function: Insert the provided data object into the database. It  Save differs from the method in that it only performs inserts and does not attempt updates.
• Create method ignores the primary key and unique index fields in the data object, and instead fills these fields with default values ​​generated by the database (such as auto-increment IDs) or random values.
• Similar to  Save methods, Create methods also return an  *gorm.DB object whose  Error properties you can use to check for errors.
