TableInfo<TableDsl extends Table, D> mixin Null safety

Base class for generated table classes.

Drift generates a subclass of TableInfo for each table used in a database. This classes contains information about the table's schema (e.g. its primaryKey or $columns).

TableDsl is the original table class written by the user. For tables defined in drift files, this is the table implementation class itself. D is the type of the data class generated from the table.

To obtain an instance of this class, use a table getter from the database.

Properties

asDslTable → TableDsl
Type system sugar. Implementations are likely to inherit from both TableInfo and Tbl and can thus just return their instance.
read-onlyoverride
$primaryKey Set<GeneratedColumn<Object>>
The primary key of this table. Can be empty if no custom primary key has been specified.
read-only
primaryKey Set<Column<Object>>
Override this to specify custom primary keys:
read-onlyoverride
uniqueKeys List<Set<GeneratedColumn<Object>>>
The unique key of this table. Can be empty if no custom primary key has been specified.
read-onlyoverride
aliasedName String
The (potentially aliased) name of this table or view.
read-onlyoverride
actualTableName String
The name of the table in the database. Unlike aliasedName, this can not be aliased.
read-only
entityName String
The (unalised) name of this entity in the database.
read-onlyoverride
columnsByName Map<String, GeneratedColumn<Object>>
Gets all $columns in this table, indexed by their (non-escaped) name.
read-only
hashCode int
The hash code for this object.
read-onlyoverride
tableName String?
The sql table name to be used. By default, drift will use the snake_case representation of your class name as the sql table name. For instance, a Table class named LocalSettings will be called local_settings by default. You can change that behavior by overriding this method to use a custom name. Please note that you must directly return a string literal by using a getter. For instance @override String get tableName => 'my_table'; is valid, whereas @override final String tableName = 'my_table'; or @override String get tableName => createMyTableName(); is not.
@visibleForOverridingread-onlyinherited
withoutRowId bool
Whether to append a WITHOUT ROWID clause in the CREATE TABLE statement. This is intended to be used by generated code only.
read-onlyinherited
dontWriteConstraints bool
Drift will write some table constraints automatically, for instance when you override primaryKey. You can turn this behavior off if you want to. This is intended to be used by generated code only.
read-onlyinherited
isStrict bool
Whether this table is STRICT.
read-onlyinherited
customConstraints List<String>
Custom table constraints that should be added to the table.
read-onlyinherited
runtimeType Type
A representation of the runtime type of the object.
read-onlyinherited
attachedDatabase DatabaseConnectionUser
The generated database instance that this view or table is attached to.
@internalread-onlyinherited
$columns List<GeneratedColumn<Object>>
All columns from this table or view.
read-onlyinherited

Methods

blob() ColumnBuilder<Uint8List>
Use this as the body of a getter to declare a column that holds arbitrary data blobs, stored as an Uint8List. Example:
@protectedinherited
boolean() ColumnBuilder<bool>
Use this as the body of a getter to declare a column that holds bools. Example (inside the body of a table class):
@protectedinherited
createAlias(String alias) TableInfo<TableDsl, D>
Creates an alias of this table or view that will write the name alias when used in a query.
override
dateTime() ColumnBuilder<DateTime>
Use this as the body of a getter to declare a column that holds date and time.
@protectedinherited
int64() ColumnBuilder<BigInt>
Use this as the body of a getter to declare a column that holds a 64-big integer as a BigInt.
@protectedinherited
integer() ColumnBuilder<int>
Use this as the body of a getter to declare a column that holds integers.
@protectedinherited
intEnum<T>() ColumnBuilder<int>
Creates a column to store an enum class T.
@protectedinherited
map(Map<String, dynamic> data, {String? tablePrefix}) FutureOr<D>
Maps the given row returned by the database into the fitting data class.
inherited
mapFromCompanion(Insertable<D> companion, DatabaseConnectionUser database) Future<D>
Converts a companion to the real model class, D.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a non-existent method or property is accessed.
inherited
real() ColumnBuilder<double>
Use this as the body of a getter to declare a column that holds floating point numbers. Example
@protectedinherited
text() ColumnBuilder<String>
Use this as the body of a getter to declare a column that holds strings. Example (inside the body of a table class):
@protectedinherited
toString() String
A string representation of this object.
inherited
validateIntegrity(Insertable<D> instance, {bool isInserting = false}) VerificationContext
Validates that the given entity can be inserted into this table, meaning that it respects all constraints (nullability, text length, etc.).
