Make new array in controller by finding id-CodePudding

I have an array with Product Ids and Color HEX Codes

Input:

@campaign.selectedproducts

Output:

["2,333333","1,333333",4,444444"]

I'm trying to make a new array with all of the product data by finding it with id:

@selectedgifts = @campaign.selectedproducts.collect [{|i| Product.find(i) }, |i| i.split(',').last]

Array should output

["Product Object, HEX code", "Product Object, HEX code"]

¿Any help?

Thanks!

CodePudding user response：

You can try with group_by method like below:

@campaign.selectedproducts.group_by(&:color_code).transform_values{|val| val.pluck(:id).uniq}

CodePudding user response：

Converting Product object to string is not what you want i guess. So i suggest you storing each element as hash instead of string.

@campaign.selectedproducts.map do |string|
  id, hex_code = string.split(',')
  product = Product.find(id)
  { product => hex_code }
end

Edit: Or you can store each element as array like this:

@campaign.selectedproducts.map do |string|
  id, hex_code = string.split(',')
  product = Product.find(id)
  [product, hex_code]
end
