import * as models from "models";

for(let model in models) {

  let attributes = models[model].attributes;

  for(let column in attributes) {
    delete attributes[column].Model;
    delete attributes[column].fieldName;
    delete attributes[column].field;
    for(let property in attributes[column]) {

  let schema = JSON.stringify(attributes, null, 2);
  let tableName = models[model].tableName;

  let template = `'use strict';
module.exports = {
  up: function(queryInterface, Sequelize) {
    return queryInterface.createTable('${tableName}', ${schema});
  },

  if(models[model].tableName !== undefined) {
    fs.writeFileSync('./tmp/' + models[model].tableName + '.js', template);
  }

};
