Prepopulate an entity reference field

Hi TD44,

On Drupal 7 there is a module that I heavily used called Entity reference prepopulate and what it does is exactly what you are asking for. Unfortunately, there is no version for Drupal 8.

I've never tried to achieve it using Business Rules and unfortunately, it's just almost possible.

• We can verify the URL to knows if you are trying to prepopulate one form field.
• We can recover this value from the URL
• We can change the form field... but there is no action to prepopulate the field with some value. I've prepered the plugin only witch actions to make the field required, optional, ready only or hidden

It's not a hard feature to implement, I'm just with no time this week and the next one to work on it, but I can do it in the second week of September.

I'm moving it to feature request.

If you or someone else has the coding skills to work on it earlier than me, the file to implement this feature is business_rules/src/Plugin/BusinessRulesAction/ChangeFieldInfo.php
