Agile Web Development with Rails 8: Iteration K3 various issues (B3 PDF p. 265-271)
- Paragraph on p 265, you no longer navigate to
http://localhost:3000/adminto login. It’s nowhttp://localhost:3000/session/new(or just try to access the support requests resource and you’ll be redirected there after login) - The screenshot at the top of page 266 shows the login prompt instead of the support requests.
- If you try to access the support requests before you set up
ActionText, you’ll get aNoMethodErroron the template. - The code snippet on pages 264-265 shouldn’t have the conditional about
<% if support_request.response.blank? %>yet if the intent is to show the index before the rich text is implemented - You need to run a
bundle installafterbin/rails action_text:installand beforebin/rails db:migratebecause the ActionText install adds in theimage_processinggem. - When the
<% if support_request.response.blank? %>section is added on pages 267-269, it is duplicated (because it was already there in error in the previous snippet). - Update controller method doesn’t use the new
params.expectconvention. It will also respond irrespective of whether theSupportRequestsuccessfully updates or not. - The
rich_text_areaoccurrences in iteration K3 and the reference in the index at the back of the book should be updated torich_textareato match current Rails convention and guides. - There is a snippet to add
SupportRequestMailer.respond(support_request).deliver_nowto the update method on page 271, but it was already present (in error) on page 269. - This is probably more of an iteration K2 issue, but the inverse relationship to
SupportRequeston theOrdermodel (has_many :support_requests, dependent: :nullify) never gets created. I discovered it when I created aSupportRequestfixture that had an order and my other tests started failing.
