Service decorator for entity list builder?

Is it possible to use a service decorator, or similar mechanism, to override a method in an entity’s list builder?

For my specific use case, I want to override the render() method of the Drupal\webform\WebformSubmisionListBuilder class, which is the list builder for the Drupal\webform\Entity\WebformSubmission entity. I’d prefer to not have to replace the list builder class entirely.

I did come across this post, but it doesn’t seem to provide a solution to my use case. I also didn’t fully comprehend the information in the post, so I might have missed the solution.

Can DDD entity rely upon infrastructure library?

Suppose I want this on my User entity:


That means:

public void createNewSecurityToken() {   var buffer = new byte[32];   new RNGCryptoServiceProvider().GetBytes(buffer);  // <--- here's the issue   this.Token = Convert.ToBase64String(buffer); } 

This is not a DI dependency, just a class from the infrastructure. But does that “break” DDD?

The alternative is this:

user.setSecurityToken(token);   // pass it in (probably from a domain service) 

But that leads to anemic entities.

Which is the preferred DDD approach, and what considerations should I take into account when faced with this sort of design decision?

Authorization using Entity Framework in ASP.NET MVC

1. Backstory

I recently starting programming and I found out that Entity Framework works perfect for my small-sized applications due its simplicity.

I’ve made my custom authorize attribute for MVC controllers and controller methods to check if the current user has a certain role (which is an enum type in my case).

The following code represents my authorize attribute:

public class HasRoleAttribute : ActionFilterAttribute {     private Role _role;      public HasRoleAttribute(Role role)     {         this._role = role;     }      public override void OnActionExecuting(ActionExecutingContext filterContext)     {         var context = new FactoryManagementContext();          var userName = filterContext.HttpContext.User.Identity.Name;         var user = context.Users.FirstOrDefault(item => item.UserName == userName);                var hasRole = user.Role == _role;          if (user == null || !hasRole)         {             // If this user does not have the             // required permission then redirect to login page             var url = new UrlHelper(filterContext.RequestContext);             var loginUrl = url.Content("/Account/Login");             filterContext.HttpContext.Response.Redirect(loginUrl, true);         }     } }  public enum Role  {     Engineer,     Manager,     Admin } 

2. Question

It works as a charm, but I have only one question: is it necessary to initialize the database context every single time when authorizing a user?

Is a refresh token an entity or value object?

I have a User entity, which may have a RefreshToken (for authentication).


  • A refresh token doesn’t have “identity”, but is related to a single user – it is only valid for that user. In the db that means a foreign key to users table. In Entity Framework I can however model it as an “owned” type so that it’s part of the users table.
  • A refresh token can be revoked, i.e. deleted from the database
  • A refresh token can be renewed – at the domain level that means replacing the old with a new one, but at the db level that means simply updating the existing record (unless it’s an “owned” type in which case I’ll update the user record)

So, is the RefreshToken an entity or a value object?

Subrequests: Assigning Paragraphs entity to node

Migrating a content type from D7 into a greenfield D8 app, so I’m using Subrequests and jsonapi modules. My first subrequest to create a simple Paragraph returns the new ID and it properly replaces my token in my node–person, until it gets wiped out at some point within the many calls to httpKernel->handle($ request) class. I’ve burned a few hours setting breakpoints to see how its losing the replaced Paragraph ID but I’ve not mastered the Symfony Http system.

I’ve tried adding an owner iid, attempted to derive a “meta” array for a target_revision_id from the drupal_internal_revision_id property but that returns a 500 error. Here’s a minimized code of the blueprint.

function bodyPerson($  person){$  data = ["data" =>       ['type' => 'node--person',        'attributes' =>         ['title' => 'ignored',         'status' =>"1",         'field_body' =>           ['value' => 'Highlights.',              'format' => 'full_html',              'summary' => ''],        'field_last_name' =>           'Walls'     'relationships'=>       [        'owner' => ['data' =>          ['type' => 'user--user',          'id' => '2061b881-d5ea-4daa-a006-616e47xxx']],        'field_title' =>['data' =>          ['type' => "paragraph--title",            'id' => "{{paragraph-title-1.body@$}}"]            ]       ]]];       return $  data;      } 
     $  bodyp = json_encode(["data" => ['type' => 'paragraph--title',        'attributes' => ['field_department' => ['value' => "my dept 1a"]],        ['field_title' => ['value' => "my title 1a"]]]]       ); 
     $  blueprint = json_encode([['action' => 'create', 'requestId' =>    'paragraph-title-1', 'body' => $  bodyp, 'uri' => '/jsonapi/paragraph/title', 'headers' => $  headers], ['action' => 'create', "waitFor" => ["paragraph-title-1"], "requestId" => "person-test", 'headers' => $  headers, 'uri' => "/jsonapi/node/person", 'body' => $  bodyPer]]); 

Passing the $ blueprint and the two body blocks into curl returns the new Paragraphs object, passing it to the final POST subrequest. The result is an empty “data” array where the Paragraphs’ link should be.

            "field_title": {                 "data": [],                 "links": {                     "self": {                         "href": "\/jsonapi\/node\/person\/9ebcdd24-d8ee-428d-8770-1ad62eexx\/relationships\/field_title?resourceVersion=id%3A1045"                     },                     "related": {                         "href": "\/jsonapi\/node\/person\/9ebcdd24-d8ee-428d-8770-1ad62exx\/field_title?resourceVersion=id%3A1045"                     }                 }             } 

Subrequests is working for other subrequests in this body.

Unica consulta em múltiplas tabelas similares – Entity Core 2.0

Tenho uma view que faz um union all em varias tabelas similares

 SELECT Id, Codigo, Descricao, TopologiaId, TipoEntidadeId FROM [dbo].[Blend]    UNION    SELECT Id, Codigo, Descricao, TopologiaId, TipoEntidadeId FROM [dbo].[Conjunto] Select.... Union....Select 

Estou removendo todas as procedures e views para consultas direto no C#

Agora estou com problemas para achar um jeito limpo de fazer o union em meu código.

Acredito que a melhor maneira não seja concatenar na hora da consulta, pois minha view tem mais de 20 tabelas mapeadas, isso deixaria o código “sujo”.

Vi alguns tópicos como POCO class e splitting mas não achei nada que me atende ainda.

Gostaria de ser capaz de fazer a consulta como

var retorno = _UnitofOr.SimilarTable.Get(); 

Onde SimilarTable retorna os registros das tabelas Blend e Conjunto

Estou usando Entity com repositório generico

entity_lookup for user entity type

I’m trying to link a field in my spreadsheet file to a user that is previously created with a migration from the same spreadsheet. The Backup column consists of multiple names divided by the backward slash (Firstname Lastname/Firstname Lastname)


process:   field_backup:     -       plugin: explode       delimiter: '/'       source: 'Backup'     -       plugin: entity_lookup       value_key: name       ignore_case: true       entity_type: user       bundle_key: uid       bundle: people 


process:     name:       plugin: concat       source:         - 'Firstname'         - 'Lastname'       delimiter: ' ' 

The backup field is just skipped when migrating the profiles. The only error I’m getting is when i go to a profile page and check the log messages.

User error: “attributes” is an invalid render array key in Drupal\Core\Render\Element::children() (regel 97 van /var/www/html/web/core/lib/Drupal/Core/Render/Element.php) #0 /var/www/html/web/core/includes/ _drupal_error_handler_real(256, ‘”attributes” is…’, ‘/var/www/html/w…’, 97, Array) #1 [internal function]: _drupal_error_handler(256, ‘”attributes” is…’, ‘/var/www/html/w…’, 97, Array) #2

/var/www/html/web/core/lib/Drupal/Core/Render/Element.php(97): trigger_error(‘”attributes” is…’, 256) #3

Can you not use entity_lookup for users or am I doing something wrong in my configuration?

Any help would be much appreciated

Entity getOwner()

In what table does an entity “foo” get its metadata stored? In Drupal 7, there are tables for all the fields for a content type and the node table had some metadata stored, but most data for a content type were in other tables. I think I understand that configuration is what metadata is required for an entity. But I cannot figure out which tables would store an association between node/100 and user/10. Using breakpoints I’m trying to troubleshoot where in the node object this info resides and try to deduce its definitions to backtrack where metadata like author/owner is stored.
