Usage

After installation you can use the command to check models:

The path to the folder with models is passed as an argument. It is important that this path must be relative to the location where the script is run from.
Also this command supports both js models and ts.

Examples of using:

Check modules

The model goes through several checks, and each of them, if it finds an error, will display it in the console.
All checks and possible messages will be listed below.

• Timestamps
  • [WARN timestamps] Model '${name}' doesn't contain '${column}'. - the model does not contain the specified column.
• Paranoid
  • [ERROR paranoid] ${name}: paranoid is true, but timestamps not enabled. - paranoid option requires timestamps.
  • [WARN paranoid] Model '${name}' doesn't contain '${column}'. - the model does not contain the specified column.
• Underscore
  • [WARN underscore] Model '${name}' contains field '${column}'. - the model contains a field containing _. This field does not have to be in the model itself. It may be that some other model, referring to this field by a foreign key, accesses it through snake_case.
• Columns
  Checks if the fields in the model match the columns in the database.
  • [ERROR column] Model '${name}' miss column '${column}'. - this column is in the database, but not in the model.
  • [ERROR column] Model '${name}' has excess column '${column}'. - there is no such column in the database.
• ServiceTables
  Checks if the table name matches the service table name (attributes, sequences, foreign_tables, etc).
  • [ERROR service-tables] Table with name ${name} is service table in database. - the specified name of the table is service.
• DataType
  • [ERROR dataType] DataType of field ${model}/${column} is defined incorrectly. Database: ${type}. Model: ${type}. Correct type: ${type} - column types in the database and in the model don't match. Try set correct type in model.
