gorm为什么不在日志中报告插入错误？

Question

I tried performing an insert using GORM and my logs displays the insert statement and says

0 rows affected or returned

If I copy and paste the insert statement, I can see this error in psql:

ERROR: null value in column "start_dt" violates not-null constraint

Is there a way for me to see this error in my go logs right away?

Answer 1

You should use gorm in debug mode to see error messages!

// Enable Logger, show detailed log
db.LogMode(true)

// Disable Logger, don't show any log even errors
db.LogMode(false)

// Debug a single operation, show detailed log for this operation
db.Debug().Where("name = ?", "jinzhu").First(&User{})
