No, you wuld do something like this:

```ruby
model = Model.new(model_params)
if model.save
  # success action, like redirect to model
else
  # failure action, like responding with the error messages in model.errors
  # setting a flash message and redirecting or rerendering the form
  # See ActiveModel::Errors on http://api.rubyonrails.org/
end
```
