create-account.hbs
```plaintext
{{#if userFields}}
{{#each userFields as |f|}}
{{user-field field=f.field value=f.value}}
{{/each}}
{{/if}}
```
js
```plaintext
var siteSettings = Discourse.SiteSettings;
console.log(siteSettings.forum_name);
complete = $(".user-field-" + siteSettings.forum_name);
```

How to check the field?
```plaintext
{{#if f.field.name == complete }} {{! doesn't work }}
OK
{{/if}}
```

set input for create-account.hbs
```plaintext
var siteSettings = Discourse.SiteSettings;
$('.control-label').each( function () {
if($(this).text().trim() === siteSettings.forum_name) {
const uuid ='lp'+(()=>([1e7]+-1e11).replace(/[018]/g,c=>(c^crypto.getRandomValues(new Uint8Array(1))[0]&15 >> c/4).toString(16)))();
var id = "user-" + $(this).parent().attr('id');
var input = $('#' + id);
input.val(uuid);
// $(this).parent().hide()
}
})
```
It looks like this
Rails.logger.warn(“#{params }”)
It looks like this
```plaintext
"user_fields"=>"true", "2"=>""}
```
“2”=\>“”
where is the second field ?

This doesn’t work because you can’t perform the actual logic calculation in a Template. This needs to be handled in the corresponding js by a Computed Property. Be sure to read [the official Ember guides (making sure you select the same version that Discourse uses)](https://guides.emberjs.com/v3.10.0/) and look at the code in one of the many popular #Customization > Plugin on here to provide you with examples.

thanks for the answer, I’m interested in examples from plugins

Here’s an example of a Computed Property from a PR I recently submitted to Ebsy’s excellent National Flags plugin: [discourse-nationalflags/assets/javascripts/discourse/components/user-nationalflags-preferences.js.es6 at master · Ebsy/discourse-nationalflags · GitHub](https://github.com/Ebsy/discourse-nationalflags/blob/master/assets/javascripts/discourse/components/user-nationalflags-preferences.js.es6)
Here’s one (“_showTimezones_”) that is actually used to hide/show in a template: [https://github.com/paviliondev/discourse-team-timezones/blob/master/assets/javascripts/discourse/components/team-display.js.es6](https://github.com/paviliondev/discourse-team-timezones/blob/master/assets/javascripts/discourse/components/team-display.js.es6)
but you’ll find tonnes of great patterns in our plugins: [Pavilion · GitHub](https://github.com/paviliondev)

Hi, I figured out how to override the action in the controllers.
example
```plaintext
import CreateAccount from 'discourse/controllers/create-account';
export default {
name: 'Create-Account-Popup',
initialize: function () {
CreateAccount.reopen({
actions: {
createAccount() {
// my code
}
}
});
}
```
How to add your `@discourseComputed` ?
I do as in the example and does not work
```plaintext
export default {
name: 'Create-Account-Popup',
@discourseComputed()
ldapForgotPassword() {
console.log('forgot!!');
return this.siteSettings.forum_login_popup_use_ldap;
},
```

Create a connector class with this code. import { set } from "@ember/object"; import EmberObject from "@ember/object"; export default { @discourseComputed("model.user\_fields.@each.value") publicUserFields() { const siteUserFields = this.site.get("user\_fields"); if (!isEmpty(siteUserFields)) { const userFields = this.get("model.user\_fields"); return siteUserFields .filterBy("show\_on\_user\_card", true) .sortBy("pos…

Happened through `@computed`
```plaintext
PreferencesAccount.reopen({
@computed
ldapForgotPassword() {
console.log('forgot!!');
return this.siteSettings.forum_login_popup_use_ldap;
},
```

You should use this to avoid a browser warning.
It’s just a different import:
```plaintext
import discourseComputed from "discourse-common/utils/decorators";
```
