After chapter 5 things are starting to gel. I’m now finding the ‘principle of least surprise’ applies:

  • "Hmm, I don’t like that validation error message. What if I add another parameter message: "my user friendly message? And it worked.
  • File upload functionality had some of the File API that looks a lot like Ruby’s, so again principle of least surprise
  • I can now work test-first more often. Tests for the Search page context were straight forward. Thanks to this forum I found the errors_on function in DataCase to write more readable and precise tests for error messages.
  • DRYing the validation for a 7 digit SKU was easy (extract function in Product and reuse that in ProductSearch.)

I skipped the image upload error handling exercise in Your Turn for now. I don’t need image uploads any time soon. It was fun to do the exercise in the chapter, as it gives more of a feel for handling state and working with files. Also, I want to skip ahead. I want to extract duplicate HTML in the search page. I copied the HTML from products/show and it looks like I need a function component for that, which is covered in the next chapter. Onward! :grinning:
