プラグイン：モーダルから toolbarEvent へのアクセス

開発

My plugin inserts a button in the composer toolbar. This toolbar opens a modal, and when the modal is closed I want to add text to the post. Everything works perfectly except the last step, because I’m struggling to give the modal access to the composer.

If I put the button under a menu in the toolbar, everything works fine:

      api.modifyClass("controller:composer", {
        pluginId: "discourse-n8n-wf",
        actions: {
          showWfModal2() {
            showModal("discourse-n8n-wf").setProperties({"toolbarEvent": this.toolbarEvent});
          },
        },
      });
      api.addToolbarPopupMenuOptionsCallback(() => {
        return {
          action: "showWfModal2",
          icon: "network-wired",
          label: "n8n workflow"
        };
      });

But if I put it on the top level, I don’t seem to have access to the toolbarEvent to pass to the modal

      Composer.reopen({
        actions: {
          showWfModal: function () {
            console.log(this.toolbarEvent); // undefined
            showModal('discourse-n8n-wf', {title:'Insert n8n workflow'});
          }
        }
      });

      api.onToolbarCreate(toolbar => {
        toolbar.addButton({
          id: 'discourse-n8n-wf',
          group: 'extras',
          icon: 'network-wired',
          action: 'showWfModal',
          title: 'Insert workflow'
        });
      });

Any tips?

The toolbarEvent should be available in your modal controller (discourse-n8n-wf), you don’t need to pass it. You can also look at how other modals do this, for example, see discourse-post-event-builder.js.es6 in the poll plugin.

Thanks, Penar! I’m not quite there yet though:

I found the file you referenced in the discourse-calendar plugin (couldn’t find it in the poll one), but there it seems like the toolbarEvent is indeed being passed in the action (through setProperties())?

Was just wondering whether you had any more thoughts here, @pmusaraj?

@sirdavidoff さん、こんにちは。

まだこの問題で詰まっているか分かりませんが、私も同様にモーダルからツールバーイベントにアクセスする方法を調べていたところ、イベントをパラメータとして次のように渡せることを見つけました。

action: (event) =>

私はこのように使用しました。

  const composerController = api.container.lookup('controller:composer');

  api.onToolbarCreate((toolbar) => {
    toolbar.addButton({
      id: 'math-editor',
      group: 'extras',
      icon: 'square-root-alt',
      sendAction: (event) => composerController.send('showMathEditor', event),
      title: themePrefix('insert_equation'),
    });
  });

そして、次のように action: {} メソッドで使用できます。

@action
showMathEditor(event) {
   showModal('matheditor-modal').set('toolbarEvent', event);
}

数年後、私も同じ問題（モーダル内でtoolbarEventにアクセスできなかった）に遭遇しましたが、この解決策は私にも有効でした。

      api.onToolbarCreate((toolbar) => {
        toolbar.addButton({
          ...
          sendAction: (event) =>
            toolbar.context.send("triggerMyModal", event),
          ...
        });
      });

      api.modifyClass("component:d-editor", {
        modal: service(),
        pluginId: "poll",
        actions: {
          triggerMyModal(toolbarEvent) {
            this.modal.show(MyCustomModal, {
              model: {
                toolbarEvent,
              },
            });
          },
        },
      });

Keeganさん、助けてくれてありがとう。
