Can not update array field in MYSQL

Question

I am working with MYSQL via Sequelize and I created a field for an array . I read that I could do this with DataTypes of JSON in MYSQL and set the default value to [] . I did this and I would like to update that field with string values. I have tried push like this:

category.dataValues.array_Of_food?.push('item1')

 await category.save()

It won't save the added item in the database. If I use the update method like this:

await category.update({array_Of_food: category.dataValues.category_name})

This changes the array_of_food field with simply a string and not an array. How do I simply push an item into the array field if this is possible?

Answer 1

I solved my problem by using this code:

  category.update({ array_Of_food: Sequelize.fn(
        'JSON_ARRAY_APPEND',
        Sequelize.col('array_of_food'),
        '$',
            food.dataValues.food_Name
      )})
