Cómo agregar campos personalizados a modelos

Plugin Extras
42

He actualizado la guía de Campos Personalizados de Temas a Discourse 3.4.0. Actualizaré la guía de categorías la próxima semana.

Hola @angus, ¡gracias por el plugin category-custom-fields!

Sin embargo, los valores no se almacenan al hacer clic en ckbdGuardar Categoríakbd:

  • La casilla de verificación de tu ejemplo sin modificar vuelve inmediatamente a sin marcar.
  • El campo personalizado no se guarda en la base de datos (lo monitoreé).

¡La imagen muestra una interfaz de usuario con opciones para “configuración de mi_campo”, con una casilla de verificación etiquetada como “mi_campo” y un botón de “Guardar Categoría” en la parte inferior. (Por IA)|422x390, 50%](upload://2pIlhH9fiTvKqIDMTleGVIzF3Ew.png)

No recibo ningún error.

¿Podrías ayudarme a averiguar esto? No puedo encontrar ninguna causa.

44

¿Existe alguna forma de asegurar en el lado del servidor que los campos personalizados sean obligatorios?

45

En un plugin, normalmente usarás el modelo ModelCustomField para añadir tus propios datos.

¿Puedes contarme más sobre lo que estás intentando hacer?

46

He añadido los campos personalizados y puedo guardarlos en la base de datos en una tabla personalizada. Sin embargo, quiero que estos campos personalizados sean obligatorios tanto en el lado del cliente como en el del servidor. En el lado del cliente, todavía es relativamente fácil. En el lado del servidor, ¿hay una forma estándar de validar que todos los campos personalizados estén llenos y luego solo permitir que se cree el tema? Ahora mismo, incluso si los campos personalizados están vacíos, el tema se crea sin ellos.

47

Ah. Eso es fácil, pero no soy lo suficientemente bueno en Rails para decirte cómo. Pero tendrás tu código detrás de un callback (Active Record Callbacks — Ruby on Rails Guides) que se llama antes de crear y fallará si tus campos no están ahí.

Hi everyone,

I set up a plugin based on Topic Custom Fields and everything was working fine until I updated Discourse to version 3.6.0.beta1-dev.

  • Topic list => OK, the columns appear correctly in the listing
  • Topic title => OK, the columns appear correctly under the topic title
  • Topic composer => KO, the fields don’t appear and I can’t compose and validate the message.

Hola @cdervout,

Problema
El componente de entrada de campo personalizado del tema utilizaba la sintaxis heredada:

{{on "change" (action @onChangeField value="target.value")}}
  • Esta sintaxis (action …) no es compatible con los componentes Glimmer modernos.
  • En consecuencia, el campo no se renderizaba en absoluto en el compositor.

Solución
Se reemplazó la sintaxis antigua por una acción Glimmer moderna:

{{on "input" this.handleInputChange}}

Y se agregó el método JS correspondiente:

@action
handleInputChange(event) {
  this.args.onChangeField(event.target.value);
}
  • Esto asegura que el campo se renderice correctamente en el compositor.

Código del componente refactorizado

import Component from "@glimmer/component";
import { Input, Textarea } from "@ember/component";
import { on } from "@ember/modifier";
import { readOnly } from "@ember/object/computed";
import { service } from "@ember/service";
import { eq } from "truth-helpers";
import i18n from "discourse-common/helpers/i18n";
import { action } from "@ember/object";

export default class TopicCustomFieldInput extends Component {
  @service siteSettings;
  @readOnly("siteSettings.topic_custom_field_name") fieldName;
  @readOnly("siteSettings.topic_custom_field_type") fieldType;

  @action
  handleInputChange(event) {
    this.args.onChangeField(event.target.value);
  }

  <template>
    {{#if (eq this.fieldType "boolean")}}
      <Input
        @type="checkbox"
        @checked={{@fieldValue}}
        {{on "input" this.handleInputChange}}
      />
      <span>{{this.fieldName}}</span>
    {{/if}}

    {{#if (eq this.fieldType "integer")}}
      <Input
        @type="number"
        @value={{@fieldValue}}
        placeholder={{i18n
          "topic_custom_field.placeholder"
          field=this.fieldName
        }}
        class="topic-custom-field-input small"
        {{on "input" this.handleInputChange}}
      />
    {{/if}}

    {{#if (eq this.fieldType "string")}}
      <Input
        @type="text"
        @value={{@fieldValue}}
        placeholder={{i18n
          "topic_custom_field.placeholder"
          field=this.fieldName
        }}
        class="topic-custom-field-input large"
        {{on "input" this.handleInputChange}}
      />
    {{/if}}

    {{#if (eq this.fieldType "json")}}
      <Textarea
        @value={{@fieldValue}}
        {{on "input" this.handleInputChange}}
        placeholder={{i18n
          "topic_custom_field.placeholder"
          field=this.fieldName
        }}
        class="topic-custom-field-textarea"
      />
    {{/if}}
  </template>
}

EDIT: He abierto un PR al respecto

¡Gracias, todo funciona bien!

He adaptado el código en el caso de que el campo sea una casilla de verificación. Para recuperar el valor, tuve que usar event.target.checked en lugar de event.target.value.
