How to create a view block of one content type filtered by author? I have a Book Club website which has a page created from a view where different members can add their recommendations. I want to create a block view which can be inserted into a Panel Page for each author, but I am struggling to get the contextual filters and relationships to work.

Below is the basic setup of the view page.



This is the contextal filter setting.



This now works if I put a user name into the context preview section.
I thought if I added a user context to the panel page this would then allow me to add the user name into the block, but I don't get this option.
I eventually got this to work by using a page view with a path /reading-list/% rather than trying to make it work through panels.
