Functions

func DeleteParentIdFilter added in v0.3.0 

func DeleteParentIdFilter(id string) func(meta ClientMeta, parent *Resource) []interface{}

DeleteParentIdFilter is mostly used for table relations to delete table data based on parent's cq_id

func ParentIdResolver 

func ParentIdResolver(_ context.Context, _ ClientMeta, r *Resource, c Column) error

ParentIdResolver resolves the cq_id from the parent if you want to reference the parent's primary keys use ParentResourceFieldResolver as required.

Types

type ClientIdentifier added in v0.9.2

type Column 

type Column struct {
	// Name of column
	Name string
	// Value Type of column i.e String, UUID etc'
	Type ValueType
	// Description about column, this description is added as a comment in the database
	Description string
	// Default value if the resolver/default getting gets a nil value
	Default interface{}
	// Column Resolver allows to set you own data based on resolving this can be an API call or setting multiple embedded values etc'
	Resolver ColumnResolver
	// Ignore errors checks if returned error from column resolver should be ignored.
	IgnoreError IgnoreErrorFunc
	// Creation options allow modifying how column is defined when table is created
	CreationOptions ColumnCreationOptions

	// IgnoreInTests is used to skip verifying the column is non-nil in integration tests.
	// By default, integration tests perform a fetch for all resources in cloudquery's test account, and
	// verify all columns are non-nil.
	// If IgnoreInTests is true, verification is skipped for this column.
	// Used when it is hard to create a reproducible environment with this column being non-nil (e.g. various error columns).
