Drupal 8.x

Drupal 8 uses the Twig templating engine
Drupal 7 uses a different templating engine.

There are many templating engines and handful of examples include
C# - razer, java - Thymeleaf, nodeJS - Jazz

I understand the need for these in languages other than PHP - the only other way to get the output of back end code into the front end page is if the WHOLE front end page is dynamically generated, without a templating engine ether the whole page is dynamically generated or nothing is.

But PHP has a feature which most languages dont.

Hi!

So I created my own module and directly beneath my mymodule-folder are the files mymodule.links.action.yml and mymodule.routing.yml.

The problem I have is, that the actions-links are not shown in the browser.

mymodule.links.action.yml

mymodule.country_add:
  route_name: mymodule.country_add
  title: 'Add Country'
  appears_on:
    - entity.mymodule_country.collection
    - entity.mymodule_country.canonical

mymodule.routing.yml

Generally when I'm trying to alter a submit handler through a form alter I do this...

array_unshift($form['#submit'], '_email_subscription_form_submit_global_handler');

But the contact form that's built into Drupal 8 has the submit handler much more nested, and I have to do this...

Hello!

I have worked with Drupal on several different projects, but this is my first time creating a Drupal 8 site on my own, so please bear with me. I am trying to create a real estate website for a small business. I need to make two pages with category lists of all properties they have for sale and all auctions that they are currently doing. However, every module that I attempt to download is meant for Drupal 7 and none of them are installing correctly. I have tried "Recipes," Taxonomy_Facets," and "Real Estate" most recently.

I just installed Drupal 8 using Drush (followed installation guidelines) and the site seems to work fine. I get a home page (probably the default one, no styling). The links like "contact" "login" etc all return 404 (i have mod_rewrite enabled on apache2).

Anyway, even /?q=admin or /?q=user do nothing (200 OK from the apache2 log file) and clean URLs all return 404.

I found nothing helpful googling this issue.

Any help?

More info:

Drupal 8.2.5
Ubuntu 16.04 LTS running under VM Workstation Player
Apache 2.4.18

Thank you,
