Functions

func DeleteParentIDFilter

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

Types

type ClientMeta

type Column

type Column struct {
	// Name of column

	// Description about column, this description is added as a comment in the database
	Description string `json:"description,omitempty"`
	// 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 `json:"-"`
	// Creation options allow modifying how column is defined when table is created
	CreationOptions ColumnCreationOptions `json:"creation_options,omitempty"`
	// 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).

}

Column definition for Table

}

type ColumnResolver

type ColumnResolver func(ctx context.Context, meta ClientMeta, resource *Resource, c Column) error

ColumnResolver is called for each row received in TableResolver's data fetch. execution holds all relevant information regarding execution as well as the Column called. resource holds the current row we are resolving the column for.

func CQUUIDResolver

func CQUUIDResolver() ColumnResolver

func ParentPathResolver

func ParentPathResolver(path string) ColumnResolver

ParentPathResolver resolves a field from the parent

func ParentResourceFieldResolver

func ParentResourceFieldResolver(name string) ColumnResolver

ParentResourceFieldResolver resolves a field from the parent's resource, the value is expected to be set if name isn't set the field will be set to null

func PathResolver

func PathResolver(path string) ColumnResolver

PathResolver resolves a field in the Resource.Item

Examples: PathResolver("Field") PathResolver("InnerStruct.Field") PathResolver("InnerStruct.InnerInnerStruct.Field")

type LengthTableValidator

type LengthTableValidator struct{}

func (LengthTableValidator) Validate

func (LengthTableValidator) Validate(t *Table) error

type Meta

type Meta struct {

}

type ResolverMeta

type ResolverMeta struct {
	Name    string

	// Set if this is an embedded table
	Parent *Resource `json:"-"`
	// internal fields

	// This is sorted result data by column name
	Data      map[string]interface{} `json:"data"`
	TableName string                 `json:"table_name"`
}

Resource represents a row in it's associated table, it carries a reference to the original item, and automatically generates an Id based on Table's Columns. Resource data can be accessed by the Get and Set methods
