The [[ do not seem to go well with the inline code. I believe I got something working with: = link(this.Author)
Note 1: link expects the full path link("path/to/" + this.Author) would be more correct. Obsidian seems to be smart about connecting links up with just the filename as long as you don’t have any notes with duplicate names in different folders of your vault!
Note 2: the one-liner DQL queries only render results in Reading View, not Live Preview, at the moment. #dataview
It did not do so for me! I am on Obsidian 0.14.15 and the most up-to-date version of dataview (Settings → Community Plugins → Check for Updates button). I don’t see anything in the dataview settings that would cause this behavior, so I wonder if some other plugin is causing it. You could try disabling different plugins, restarting obsidian, testing if the behavior changed, re-enable the plugins and/or disable different ones, restart obsidian, test again, etc. (Key here is to restart Obsidian after you change your plugin configuration to make sure the changes have “stuck”.)
