Question

I am writing code to clone object but have no cue from Hobo documentation.

I know how to do it in Rails but it seems no intuitive way to do it in Hobo.

The scenario is to add an button on a record page, clone an existing record, and redirect to new record after the creation.

For example

POST /papers/10/clone

Then the new record 123 will be created.

After that action, it will redirect to page /papers/123

Are there any examples and guides to achieve the scenario?

If Paper has many Comments, how to clone them as well without permission errors?

Answer 1

Hobo doesn’t have any special support for cloning an object, so you’ll have to drop down to Rails to do it:

def clone
  paper = Paper.find(params[:id])
  fail if paper.nil?
  clone = paper.clone
  clone.save!
  redirect_to paper_path(clone)
end

You could add this new controller action to your routes via Hobo’s web_method hook, but that’s designed for something else. You’re better off just adding it to your config/routes.rb in a standard Rails fashion.
