如何允许参数中带有 id 键的 hash？

Question

Having this kind of params where 14 and 5 are keys. They are not randomly generated. Those are payment_ids(ask you can see).

<ActionController::Parameters {"14"=>{"customer_id"=>"28", "payment_id"=>"14", "plan_id"=>"121"}, "5"=>{"customer_id"=>"28", "payment_id"=>"5", "plan_id"=>"7"}} permitted: false>

So my question would be how correctly permit params?

I understand that I need to do something like this but in a current way "14" is hardcoded and static

params.require(:param_name).permit("14" => {})

This seems to be working given your example:

# Find the keys that are 1-2 digit numbers
numeric_param_keys = params.keys.select { |key| key =~ /\A\d{1,2}\z/ }
# Create an array of hashes from those numeric keys
permissions = numeric_param_keys.map { |key| { key => {} } }
params.permit(permissions)
