	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'

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 bieng called. resource holds the current row we are resolving the column for.

func ParentPathResolver

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 Database

type Database interface {
	Insert(ctx context.Context, t *Table, instance []*Resource) error
	Exec(ctx context.Context, query string, args ...interface{}) error
	Delete(ctx context.Context, t *Table, args []interface{}) error
	Query(ctx context.Context, query string, args ...interface{}) (pgx.Rows, error)
}

type ExecutionData

type ExecutionData struct {
	// Table this execution is associated with
	Table *Table
	// Database connection to insert data into
	Db Database
	// Logger associated with this execution
	Logger hclog.Logger
	// contains filtered or unexported fields
}

ExecutionData marks all the related execution info passed to TableResolver and ColumnResolver giving access to the Runner's meta

func NewExecutionData

func NewExecutionData(db Database, logger hclog.Logger, table *Table, disableDelete bool, extraFields map[string]interface{}) ExecutionData

NewExecutionData Create a new execution data

func (ExecutionData) ResolveTable

func (e ExecutionData) ResolveTable(ctx context.Context, meta ClientMeta, parent *Resource) (uint64, error)

func (ExecutionData) WithTable

func (e ExecutionData) WithTable(t *Table) ExecutionData

type IgnoreErrorFunc

type IgnoreErrorFunc func(err error) bool

IgnoreErrorFunc checks if returned error from table resolver should be ignored.

type LengthTableValidator

type LengthTableValidator struct{}

func (LengthTableValidator) Validate

func (tv LengthTableValidator) Validate(t *Table) error

type PgDatabase

type PgDatabase struct {
	// contains filtered or unexported fields
}

func NewPgDatabase

func NewPgDatabase(ctx context.Context, dsn string) (*PgDatabase, error)

func (PgDatabase) Delete

func (p PgDatabase) Delete(ctx context.Context, t *Table, args []interface{}) error

func (PgDatabase) Exec

func (p PgDatabase) Exec(ctx context.Context, query string, args ...interface{}) error

Exec allows executions of postgres queries with given args returning error of execution

func (PgDatabase) Insert

func (p PgDatabase) Insert(ctx context.Context, t *Table, resources []*Resource) error

Insert inserts all resources to given table, table and resources are assumed from same table.

func (PgDatabase) Query

func (p PgDatabase) Query(ctx context.Context, query string, args ...interface{}) (pgx.Rows, error)

Query allows execution of postgres queries with given args returning data result

func (PgDatabase) QueryOne

func (p PgDatabase) QueryOne(ctx context.Context, query string, args ...interface{}) pgx.Row

QueryOne allows execution of postgres queries with given args returning data result

type Resource

type Resource struct {
	// Original resource item that wa from prior resolve
	Item interface{}
	// Set if this is an embedded table
	Parent *Resource
	// contains filtered or unexported fields
}

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
