Ability to reference an entity and auto open its edit form

Sorry for the delay in responding to this, we've been busy refactoring and cleaning up the codebase.

If I understood correctly, you want the ability to specify a reference in the URL of the add form (node/add/page?article=12), have IEF pick up that value, and auto open the edit form?

I was able to make the first part of this work with a defaultValueCallback on the parent ER field that looks like this:

  public static function prefillDefaultTeamMember() {
    $list_values[] = [
      'entity' => OrganisationTeamMember::create([
        'full_name' => 'User no1',
      ]),
    ];

    return $list_values;
  }

However, I wasn't able to make IEF default to open the form with the default values.

This is what I am needing to do as well. Prepopulate is working on a being able to preselect the reference #3029328. But how would you have it auto open the edit form?

I have added a simple helper method which allows /node/90010/edit?ief_open[]=paragraph:616562&ief_open[]=paragraph:616558 style URLs to work. I immediately use it in this patch but I also have an InlineParagraphsWidget patch which changes if ($default_edit_mode == 'open') { to if (InlineEntityFormBase::entityIsOpenFromQuery($paragraphs_entity, $form_state) || $default_edit_mode == 'open') { and now the children of those widgets open too.

I believe this is the same as inline_entity_form_open_row_form setting edit and so subsequent button presses will behave correctly / same.

One more thing: let's make it possible to scroll to the opened form.

Reroll.

tnx

Bulk reopen.

Review: I like this a lot. Needs a test though.
