SQLite does not support addForeignKey() #218

Description

@Tigrov

SQLite does not support addForeignKey() but supports foreign key constraints inside columns definitions of CREATE TABLE query.

https://www.sqlite.org/foreignkeys.html

CREATE TABLE track(
  trackid     INTEGER, 
  trackname   TEXT, 
  trackartist INTEGER,
  FOREIGN KEY(trackartist) REFERENCES artist(artistid)
);

The follow command throws an Exception in SQLite

./yii migrate:create post --command=table --fields='department_id:integer:notNull:foreignKey(department)'

Due to column foreign key is initialized separately

echo " \$b->createTable('$table', [\n";
foreach ($columns as $column) {
if (!$column->hasDecorators()) {
echo " '{$column->getProperty()}',\n";
} else {
echo " '{$column->getProperty()}' => \$b->{$column->getDecoratorsString()},\n";
}
}
echo " ]);\n";
echo $this->render(__DIR__ . '/_addForeignKeys.php', [
'table' => $table,
'foreignKeys' => $foreignKeys,
]);
