Can someone please explain to me how the User Card pop-up works?

Guys, i’m trying to work out how the code for User Card works.

How does it create a pop-up and then escalate to a new page?

<a href="/u/postinguser" data-user-card="postinguser" class=""><img alt="" src="/letter_avatar_proxy/v2/letter/m/bbce88/50.png" class="avatar" title="User - Frequent Poster" width="25" height="25"></a>

I can see how it is constructed from the .hbs template file, but not how the action of clicking it causes the user card to appear …

<a href="{{poster.user.path}}" data-user-card="{{poster.user.username}}" class="{{poster.extraClasses}}">{{avatar poster avatarTemplatePath="user.avatar_template" usernamePath="user.username" imageSize="small"}}</a>

But how does the javascript fit together?

What code is causing the user card to load instead of going to the user route?

I see:

/app/assets/javascripts/discourse/widgets/poster-name.js.es6

and specifically:

export default createWidget("poster-name", {
  tagName: "div.names.trigger-user-card",

  settings: {
    showNameAndGroup: true,
    showGlyph: true
  },

  // TODO: Allow extensibility
  posterGlyph(attrs) {
    if (attrs.moderator) {
      return iconNode("shield", { title: I18n.t("user.moderator_tooltip") });
    }
  },

  userLink(attrs, text) {
    return h(
      "a",
      {
        attributes: {
          href: attrs.usernameUrl,
          "data-user-card": attrs.username
        }
      },
      formatUsername(text)
    );
  },

  html(attrs) {
    const username = attrs.username;
    const name = attrs.name;
    const nameFirst =
      this.siteSettings.display_name_on_posts &&
      !this.siteSettings.prioritize_username_in_ux &&
      name &&
      name.trim().length > 0;
    const classNames = nameFirst
      ? ["first", "full-name"]
      : ["first", "username"];

    if (attrs.staff) {
      classNames.push("staff");
    }
    if (attrs.admin) {
      classNames.push("admin");
    }
    if (attrs.moderator) {
      classNames.push("moderator");
    }
    if (attrs.new_user) {
      classNames.push("new-user");
    }

    let afterNameContents =
      applyDecorators(this, "after-name", attrs, this.state) || [];

    const primaryGroupName = attrs.primary_group_name;
    if (primaryGroupName && primaryGroupName.length) {
      classNames.push(primaryGroupName);
    }
    let nameContents = [this.userLink(attrs, nameFirst ? name : username)];

    if (this.settings.showGlyph) {
      const glyph = this.posterGlyph(attrs);
      if (glyph) {
        nameContents.push(glyph);
      }
    }
    nameContents = nameContents.concat(afterNameContents);

    const contents = [
      h("span", { className: classNames.join(" ") }, nameContents)
    ];

    if (!this.settings.showNameAndGroup) {
      return contents;
    }

    if (
      name &&
      this.siteSettings.display_name_on_posts &&
      sanitizeName(name) !== sanitizeName(username)
    ) {
      contents.push(
        h(
          "span.second." + (nameFirst ? "username" : "full-name"),
          [this.userLink(attrs, nameFirst ? username : name)].concat(
            afterNameContents
          )
        )
      );
    }

    const title = attrs.user_title;
    if (title && title.length) {
      contents.push(
        this.attach("poster-name-title", { title, primaryGroupName })
      );
    }

    return contents;
  }

Can someone talk me through this latter code wrt to launching the user card in a state which will permit a further click to the user’s profile?

I think you’re looking for card-contents-base.js.es6, which defines a series of events which point to the _show method.

# card-contents-base.js.es6#103
$("#main-outlet").on(clickDataExpand, `[data-${id}]`, e => {});

$("#main-outlet").on(clickMention, `a.${triggeringLinkClass}`, e => {});

this.appEvents.on(previewClickEvent, $target => {});

# card-contents-base.js.es6#20
_show(username, $target) {}

Thanks James! I’ll have a read through that code … head spinning already though … :slight_smile:

What is the thing that you’re trying to do?

Trying to understand how the user card is wired in so I can ultimately code the same behaviour in a plug-in.

@merefield avez-vous réussi à trouver comment faire cela ?

J’essaie de comprendre comment créer un composant de thème pour modifier la carte utilisateur du plugin Emplacements afin que lorsqu’elle est cliquée, elle affiche la carte de profil au lieu d’aller directement à la page de profil, mais je n’ai aucune idée par où commencer ou chercher.

oh, c’est vieux de 5 ans… je ne m’en souviens plus :sweat_smile: … j’imagine que le code est très différent maintenant.

J’accepterais cette fonctionnalité comme une PR pour Locations car elle a été demandée plusieurs fois auparavant.

haha oui ça a du sens. Je vais peut-être me pencher dessus bientôt et si je découvre comment faire des PR de plugins, je les proposerai :folded_hands:t2:
