常见的想当然

A conditional Preload filters root parent records and Joins can load a HasMany slice association in GORM 1.31.2.

这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。

契约

• assert Preload with a condition returns both parent records and leaves the nonmatching parent's child slice empty
• assert Preload plus a root Where on the unjoined child table returns a no such column SQL error
• assert Joins on the tested HasMany slice relation panics during reflection instead of populating the slice
• assert Joins on the tested HasOne relation returns one matching parent and populates its nested struct
• assert an explicit SQL join with Distinct filters the parent records and conditional Preload attaches the matching child
• assert plain Delete leaves the seeded child rows present in the test database
• assert Select with clause.Associations on Delete removes the seeded child rows
• assert Omit with clause.Associations on Create inserts only the parent row
