Schema::table('posts', function (Blueprint $table) {
$table->dropForeign(['category_id']);
});Schema::table('posts', function (Blueprint $table) {
$table->unsignedBigInteger('user_id');

OR
Schema::table('posts', function (Blueprint $table) {
$table->foreignId('user_id')->constrained();
});//...
class ClearOldOauthRelations extends Migration
{
public function up()
{
Schema::disableForeignKeyConstraints();
// drop foreign keys
Schema::table('oauth_access_tokens', function (BluePrint $table) {
$table->dropForeign('oauth_access_tokens_session_id_foreign');
});
//...
Schema::enableForeignKeyConstraints();
}
//...
}
Schema::table('table_name', function (Blueprint $table) {
$table->dropForeign(['foreign_key']);
$table->dropColumn('column_key');
});
PS: usually foreign_key = column_key
ex:
Schema::table('despatch_discrepancies', function (Blueprint $table) {
$table->dropForeign(['pick_detail_id']);
$table->dropColumn('pick_detail_id');
}); public function down()
{
Schema::table('tarefas', function (Blueprint $table) {
$table->dropForeign('tarefas_user_id_foreign');
$table->dropColumn('user_id');
});
}Schema::table('admins', function (Blueprint $table) { $table->dropForeign('admins_post_id_foreign'); $table->dropColumn('post_id');});
