When i call lastest.json?page=0&per\_page=10&foo=bar

```plaintext
     # TypeError:
     # String can't be coerced into Integer
     # ./lib/topic_query.rb:729:in `*'

```

I think can resolve by:

```plaintext
if options[:page]
  offset = options[:page].to_i * options[:per_page].to_i
  result = result.offset(offset) if offset > 0
end

```

This is a bit of a feature request, per\_page is not part of our API (not used by the client at all). This would not fully solve the issue cause per\_page would need to come with an upper limit of say maximum of 100-200.

Is there a specific reason you are looking to override page sizes?

Yes, We have a customer page to get the topics with waterfall flow.  
Sure I think this is a feature request.  
We can use default per\_page and remove the per\_page query.
