Drupal 8.x

In one node content type, there are several reference fields.
How can I limit them to these referenced entities and embed them in the body?
I want to create a rule that can be embedded in the body only once after registering it in the reference field.

This behavior is similar to an insert module.
However, the insert module can insert media at 8.6 or later, but can not insert node or term.

Referenced content is node, media, and term.
The content to embed after the association is node, media, and term.

Views Backend stops working on Drupal 8 sites.....

There are no exact error or anything, just unable to edit New Views..... unable to click any ajax settings like field, criteria, node address, etc...

It happens for Newly Created Views.....

I very often create new views by Duplicating Views - those Views work and are editable.....

but New Created Views - doesn't work.... No errors...

Can some one give me an insight on how to approach this form in Drupal 8?

I have the following node/add form of my custom node typ:.

The paragraph field_para_city contain one field_city. (I later need to add other fields in the paragraph).

The user can add multiple instances from field_para_city.

field_city has an allowed_values_function defined in a YML file, which returns all possible cities from all countries.

Yeah, I badly need Jquery in my basic/ text/javascript module for dropdown combo menu.....

I used to have only google/1.8.3/js.min link in D7 times and it was working....

Now - it is still working, when I Log Out..... For Anonimous Users - it work fine, but not for Logged in User....

And it doesn't stop there.... I think most other Modules are loading very badly for Admin user.....

Views Ajax Mini-pager in block - also - doesn't work for Admin, but Log out and it work....

I've searched this forum and on google on my Drupal 7 to Drupal 8 upgrade problem, but found no success.

I am attempting to upgrade my Drupal 7 site at http://club.my-kart.org to my new install of Drupal 8 at https://my-kart.org/d8

I've done the preparation according to https://www.drupal.org/docs/8/upgrade/preparing-a-site-for-upgrade-to-dr...

Hello,

In the past 13 or so days, I had nothing but frustrations trying to get started learning Drupal 8 custom module development. Reading the online documentation, example, purchasing 2 eBooks, watching 2 Lynda.com video series, watching another series on YouTube, and I am not even close to understand what this is all about and how this works. Not to mention, why does this has to be so complex!?

I'm not looking for a line-by-line code solution, just a general guideline/idea on how should I go about doing this simple sample exercise I came up with.
