Clone Sequel Model

Question

I have a Model representing a Pricing Table with lots of entries and i want to offer the possibility to create a new Pricing with values from an existing entry. Does anyone know how to do this, then Sequel is in use? I tried dup and clone but in both cases the id is still there from the existing Model and thus will update the existing entry. If i try to set the id by hand i get following error: ``` Sequel::InvalidValue: nil/NULL is not allowed for the id column ``` So i need a to find a Way to create a Model which is new but has prefilled values without having them to set in the code by hand. Any ideas?

Accepted Answer

found it:

```
new_pricing = Pricing.new(oldprice.attributes.tap{|attr| attr.delete("id")})
```

i get the attributes from the old model as hash, then remove the id and create a new Model by passing the attributes except the id.
