Bulk creating objects with nested attributes in ruby-CodePudding

We are encountering a problem in a new app we are creating. We have two models: Packages and products, a package has many products. We need to create a controller that can bulk create packages so we started using the activerecord-import gem which allows for bulk creates. However the problem is that the gem does not allow for the use of nested attributes to create products, which means I cannot create the corresponding products for each package. Has anyone encountered a similar problem or have any potential elegant solutions?

The JSON for the controller would be similar as below.

{
  packages: [
    {
      weight: 'x',
      products_attributes: [
        {
          code: x
        },
        {
          code: x
        }
      ]
    },
    {
      weight: 'y',
      products_attributes: [
        {
          code: y
        },
        {
          code: y
        }
      ]
    },
  ]
}

CodePudding user response：

books = 10.times.map do |i|
  book = Book.new(name: "book #{i}")
  book.reviews.build(title: "Excellent")
  book 
end
Book.import books, recursive: true

You can try this, iterate your hash, and build objects for packages, and for each package, iterate products, and build products objects assigned to package object. Another way - is build raw SQL, but it's harder
