I'm creating and saving a form using Ember but when I reload the page the toggle keeping track of whether the form has been submitted or not resets to false.
I have a page where the default text is 'You have no account linked'. I then have a button that when pressed displays a form for the user to fill out information . When they click submit and save their information, the form disappears and renders some text about their account. When I reload the page however the text renders to the default 'You have no account linked', and when I click the submit form button, their information is populated in the form fields. How can I ensure that when the page is reloaded the text about the user account is displayed?
This is the controller for the page
export default Controller.extend({
isToggled: false,
emailConnected: false,
actions: {
submitImap(mailbox, toggle, email) {
this.get('ajax').request(`/api/accounts/${this.session.account.id}/mailboxes/imap`, {
method: 'POST',
data: mailbox
})
.then(() => Utils.notify("IMAP settings saved.", 'success'))
.catch(() => Utils.notify("Error saving IMAP account. Try again", 'error'));
this.send('contract', toggle);
this.send('expand', email);
},
disconnectIMAP(mailbox, property, email) {
this.get('ajax').request(`/api/accounts/${this.session.account.id}/mailboxes/imap`, {
method: 'DELETE',
data: {
user_id: mailbox.user_id
}
}).then(() => {
this.set(property, { smtp: {}});
})
.then(() => Utils.notify("IMAP removed. ", 'success'))
.catch(() => Utils.notify("Error removing IMAP account", 'error'));
this.send('contract',email );
},
expand: function(toggle) {
this.set(toggle, true)
},
contract: function(toggle) {
this.set(toggle, false)
}
}
});
This is the template handling the form submission

Right now, if I submit the form the behavior is as expected, displaying the current username of the account, but on reload the emailConnected variable resets to false and the default of 'you have no account connected' is present and when I click the form the values are populated.
If you reload the page (or) switch to a different route, the controller's property isToggled will reset to its initial state (i.e) to false in your case.
If you want to maintain the state and make use of the property isToggled at various parts of your application, you can use ember service
But in your case, you want to maintain the property state even after the page reloads. ember service doesn't maintain the state after the page reloads.
Here comes the use of browsers localStorage
So, in your case -
1) store the value of the property isToggled in browsers localStorage
import { computed } from '@ember/object';
export default Controller.extend({
isToggled: computed(function () {
// when the user visits the page for the very first time,
// isToggled value is set to false,
// from next time it gets the value from browsers localStorage.
if (localStorage.isToggled) {
return JSON.parse(localStorage.isToggled);
} else {
return false;
}
}),
...
actions: {
...
expand: function() {
localStorage.setItem('isToggled', JSON.stringify(true));
this.set('isToggled', true);
},
contract: function() {
localStorage.setItem('isToggled', JSON.stringify(false));
this.set('isToggled', false);
}
...
}
});
Now when the page is reloaded the isToggled property state doesn't change to the initial state.
You can find the isToggle browsers localStorage variable in your browsers developer tool: Application -> Local Storage tab
