Title: Pagination: Next/Previous related to author
ThreadText: # Pagination: Next/Previous related to author
  
  (Asked by: username_0 on 2018-10-10)
  
  I'm having trouble limiting next/previous links in one channel to articles by the author.
  
  next/previous links are working correctly on the regular blog but when included on the DJ blog I get `unknown property errors` in the template.
  
  If I remove the **merge** line below pagination appears to work, but includes DJ posts not by the current Dj.
  
  url looks like `https://domain.com/djs/503/firstName-lastName` where 503 is the author.id

  You are trying to merge an object of type `ElementQuery` with an array so your object will be transformed as an array and merged with the new array. Of course you'll end up having an array instead of a query so you can't execute it in order to fetch the entries.
  
  Instead of merging it, why not setting the parameter directly?
  
  ```
  {% do param.authorId(author) %}
  
  ```
  
  Furthermore authors are not related to entries (except you set them in an additional field)
