Workflow
We use the module "Users" as example
- Create a metadata description: lib/meta/users_meta.dart
import 'module_meta_data.dart';
class UserMeta extends ModuleMetaData {
static UserMeta instance = UserMeta.internal();
UserMeta.internal() : super('Users',
[
PropertyMetaData('id', DataType.reference, ':primary:', 'combo'),
PropertyMetaData('name', DataType.string, ':notnull:', '', size: 64),
PropertyMetaData('displayName', DataType.string, ':unique:notnull:', '', size: 32),
PropertyMetaData('email', DataType.string, ':unique:notnull:', '', size: 255),
PropertyMetaData('role', DataType.reference, ':notnull:', ''),
PropertyMetaData('created', DataType.datetime, '', ''),
PropertyMetaData('createdBy', DataType.string, '', '', size: 32),
PropertyMetaData('changed', DataType.datetime, '', ''),
PropertyMetaData('changedBy', DataType.string, '', '', size: 32),
],
tableName: 'loginusers',
);
factory UserMeta(){
return instance;
}
}
- Create some source files: (for example: the module "Users")
# precondition: the current directory is the base folder of the dev-app.
mkdir -p lib/meta/users
# The following call works without meta data. It works without recreation of the tool:
meta_tool print-modules Users >lib/meta/modules.dart
# Now we need a new instance of the meta_tool (to realize the meta data changes):
./ReCreateMetaTool
meta_tool print-data Users >lib/page/users/user_data.dart
# show the SQL table definition:
meta_tool print-table
- Create all source files:
# precondition: the current directory is the base folder of the dev-app.
# The following call works without meta data. It works without recreation of the tool:
meta_tool update-modules-list
# Now we need a new instance of the meta_tool (to realize the meta data changes):
./ReCreateMetaTool
meta_tool update-modules
