Rails 6 API What are good practices for sending and serializing data?

Question

I have problem and I don't know how to solve it in a correct way. In my front-end app I have select which shows all products, so I need to send request to my Rails API. Controller has method index that sends all products, but with many different attributes and associations. I don't think so it's a good idea to send request to this method, because in <select> I need only product name and id. Example:

ProductController.rb

 def index
   render json: @products, include: 'categories, user.company'
 end

ProductSerializer.rb

class ProductSerializer < ActiveModel::Serializer
  attributes :id, :name, :desc, :weight, :amount, ...

  belongs_to :user
  has_many :categories
end

As u can see ProductSerializer send many things and it is expected but in a different view in FE app. In another page I need only id and name attributes to <select>. I know that I can create new Serializer and add if like this:

  def index
    render json: @product, each_serializer: ProductSelectSerializer and return if pramas[:select]
    render json: @products, include: 'categories, user.company'
  end

But I'm not sure is a good idea to create new Serializer only for one request, because in bigger application can be many situations like this. This if in index method dose not looks good too in my opinion, so maybe I should create new method for this request, but it's worth for one small request? Are there any good practices that can help to properly resolve such situations?
