Mutations#

In this chapter, you’ll learn how to create, update and delete objects from you database using Pop.

Create#

Without validation#

c, err := pop.Connect("development")
// [...]
fruit := &models.Fruit{}
// Create a fruit without running validations
err := c.Create(fruit)

With validation#

c, err := pop.Connect("development")
// [...]
fruit := &models.Fruit{}
// Run validations and create if all validations passed
vErrors, err := c.ValidateAndCreate(fruit)

Update#

Without validation#

c, err := pop.Connect("development")
// [...]
fruit := &models.Fruit{}
// Update a fruit without running validations
err := c.Update(fruit)

With validation#

c, err := pop.Connect("development")
// [...]
fruit := &models.Fruit{}
// Run validations and update if all validations passed
vErrors, err := c.ValidateAndUpdate(fruit)

Save#

Save checks for the ID in you model: if the ID is the zero value of the type (so for example if it’s an int and its value is 0), Save calls Create. Otherwise, it calls Update.

Without validation#

c, err := pop.Connect("development")
// [...]
fruit := &models.Fruit{ID: 0}
// Create a fruit without running validations
err := c.Save(fruit)

c, err := pop.Connect("development")
// [...]
fruit := &models.Fruit{ID: 1}
// Update a fruit without running validations
err := c.Save(fruit)

With validation#

c, err := pop.Connect("development")
// [...]
fruit := &models.Fruit{ID: 0}
// Run validations and create if all validations passed
vErrors, err := c.ValidateAndSave(fruit)

c, err := pop.Connect("development")
// [...]
fruit := &models.Fruit{ID: 1}
// Run validations and update if all validations passed
vErrors, err := c.ValidateAndSave(fruit)

Delete#

c, err := pop.Connect("development")
// [...]
fruit := &models.Fruit{ID: 1}
// Destroy the fruit
err := c.Destroy(fruit)
