Fix

Technical

Remove if/else condition, uses the lst['key'] to determine if the user is the owner of the list and show relevant components within the account/view.html template.

Testing

• Create two user accounts and use one account to create a list of books
• Navigate to the list page and check that the follow button does not appear within the list of lists and single list webpages.
• Sign out of the list creator account and sign into the other newly created account.
• Navigate to the created book list, verify that the follow button appears on the list page and that pressing follow will add the creator's account to the visitor's Following tab.
