Come aggiungere campi personalizzati ai modelli

Plugin Extra
42

Ho aggiornato la guida dei Campi Personalizzati dell’Argomento a Discourse 3.4.0. Aggiornerò la guida delle categorie la prossima settimana.

Ciao @angus, grazie per il plugin category-custom-fields!

Tuttavia, i valori non vengono salvati quando si fa clic su Salva categoria:

  • La casella di controllo del tuo esempio non modificato torna immediatamente a non selezionata.
  • Il campo personalizzato non viene salvato nel database (l’ho monitorato).

L'immagine mostra un'interfaccia utente con opzioni per le impostazioni di "my_field", caratterizzata da una casella di controllo etichettata "my_field" e un pulsante "Salva categoria" in basso. (Didascalia dell'IA)

Non ricevo errori.

Potresti aiutarmi a capire? Non riesco a trovare alcuna causa.

44

C’è un modo per assicurarsi lato server che i campi personalizzati siano obbligatori?

45

In un plugin, di solito si utilizza il modello ModelCustomField per aggiungere i propri dati.

Puoi dirmi di più su cosa stai cercando di fare?

46

Ho aggiunto i campi personalizzati e sono in grado di salvarli nel database in una tabella personalizzata. Tuttavia, voglio rendere questi campi personalizzati obbligatori sia lato client che lato server. Sul lato client è ancora relativamente facile. Sul lato server, esiste un modo standard per convalidare che tutti i campi personalizzati siano compilati e quindi consentire solo la creazione dell’argomento. Al momento, anche se i campi personalizzati sono vuoti, l’argomento viene creato senza di essi.

47

Ah. È facile, ma non sono abbastanza bravo con Rails per dirtelo. Ma avrai il tuo codice dietro un callback (Active Record Callbacks — Ruby on Rails Guides) che viene chiamato prima della creazione e fallirà se i tuoi campi non ci sono.

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.

Ciao @cdervout,

Problema
Il componente di input del campo personalizzato dell’argomento utilizzava la sintassi legacy:

{{on "change" (action @onChangeField value="target.value")}}
  • Questa sintassi (action …) non è supportata nei componenti Glimmer moderni.
  • Di conseguenza, il campo non veniva affatto visualizzato nel composer.

Correzione
Sostituita la vecchia sintassi con un’azione Glimmer moderna:

{{on "input" this.handleInputChange}}

E aggiunti il metodo JS corrispondente:

@action
handleInputChange(event) {
  this.args.onChangeField(event.target.value);
}
  • Ciò garantisce che il campo venga visualizzato correttamente nel composer.

Codice del componente rifattorizzato

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);
  }

    {{/if}}

    {{#if (eq this.fieldType "string")}}

        placeholder={{i18n

}

MODIFICA: Ho aperto una PR per lo stesso

Grazie, tutto funziona perfettamente!

Ho adattato il codice nel caso in cui il campo sia una casella di controllo. Per recuperare il valore, ho dovuto usare event.target.checked invece di event.target.value
