I will try to explain in detail the essence of the problem that I recently encountered. According to the textbook wrote a simple online store. Without design, with bare buttons and input fields everything was fine. But when I started working on the selection of color, something went wrong - the description of the laid out goods was not visible, more precisely, they simply did not exist.

The order of my work.

  1. At first I made changes to the seeds file - more precisely, I simply copied them from the website of the textbook and pasted them.

  2. Then I worked with the SASS language, in the file depot/app/assets/stylesheets/products.css.scss , by writing the following:

     /* START_HIGHLIGHT */ .products { table { border-collapse: collapse; } table tr td { padding: 5px; vertical-align: top; } .list_image { width: 60px; height: 70px; } .list_description { width: 60%; dl { margin: 0; } dt { color: #244; font-weight: bold; font-size: larger; } dd { margin: 0; } } .list_actions { font-size: x-small; text-align: right; padding-left: 1em; } .list_line_even { background: #e0f8f8; } .list_line_odd { background: #f8b0f8; } }

  3. The file in the /depot/app/views/layouts/application.html.erb directory ( here it is ) I changed the fourth line from the end (from <body> to what is available now).

  • I think it is more appropriate to ask this question on the lesson resource. It is unlikely that there is someone in the subject of all the details of what is happening. Information is extremely small. - SlyDeath
  • Roll back the changes you made step by step until the data comes back. this will allow you to localize your (or textbook writers) error. but in general, of course, it was necessary to refer to the source. - aleksandr barakin
  • Tell me which page of your online store do you visit? If localhost:3000/products , then send the contents of the file app/views/products/index.html.erb . - installero
  • What does "not exist" mean? Is this code that the tracks did not render? - Mal Skrylev

Try to “roll back” step by step all the changes you made until the data “go back”.

This will allow you to localize your (or author of the textbook) error.

but in general, of course, it would be worth referring to the original source: the author of the textbook.
