sequelize updating a table code example

Example 1: create or update in sequelize

async function updateOrCreate (model, where, newItem) {
    // First try to find the record
   const foundItem = await model.findOne({where});
   if (!foundItem) {
        // Item not found, create a new one
        const item = await model.create(newItem)
        return  {item, created: true};
    }
    // Found an item, update it
    const item = await model.update(newItem, {where});
    return {item, created: false};
}

Example 2: update column with find sequelize

Project.find({ where: { title: 'aProject' } })
  .on('success', function (project) {
    // Check if record exists in db
    if (project) {
      project.update({
        title: 'a very different title now'
      })
      .success(function () {})
    }
  })
