I'm trying to usé Realm database un à flutter project. How to update an entier object? It is hard to do it property by property.
I find a solution:It consists of adding setting update = true in add method.
realmDb.write<ObjectModel>(() => realmDb.add<ObjectModel>(newValue, update: true));

What I'm trying to do is to add a new reference to this object:
Just insert a new element inside "citas". This is what I have so far.
database.collection('NegociosDev').doc('Peluquerías')
.collection('Negocios').doc('PR01').collection('empleados').where('Nombre', '==','Ale')...
I guess I shouldn't use "add()" as it is used to add a new document right? Any ideas?
Indeed, you should update your document this way:
database.collection('NegociosDev').doc('Peluquerías').update({
citas: firebase.firestore.FieldValue.arrayUnion("new value")
})
I have implemented Google enhanced Ecommerce Via GTM for GA Property (New), keeping the old classic analytics code in the webiste, Now I removed the old classic code and pushing the events data from the same GTM account to (old) GA property (Replicated the Tags with different GA Property, Reference url : http://www.kristaseiden.com/step-by-step-adding-a-second-ga-property-via-google-tag-manager/).
The first GA property transactions are used to track properly, But after adding another GA property the transactions and all other events are not tracking accurately. In both the accounts Transactions are dropped to 50 percent.
Could someone help me. Thanks in advance.
You can create a custom JS variable:
function() {
var newTrackingId = 'UA-XXXXXX-XX'; // Replace here
var globalSendTaskName = '_' + newTrackingId + '_originalSendTask';
return function(customModel) {
window[globalSendTaskName] = window[globalSendTaskName] || customModel.get('sendHitTask');
customModel.set('sendHitTask', function(sendModel) {
var hitPayload = sendModel.get('hitPayload');
var trackingId = new RegExp(sendModel.get('trackingId'), 'gi');
window[globalSendTaskName](sendModel);
sendModel.set('hitPayload', hitPayload.replace(trackingId, newTrackingId), true);
window[globalSendTaskName](sendModel);
});
};
}
And then add this as a custom task on fields to set:
Hope it helps!

How do I update WordPress user role capability value through the database? i want to add custom capability like as post_limit, then update those post limit value
Below is a screenshot showing the wp_user_roles options;
wp_user_roles => value (i want to update this unserialized value)
Note: i want to update existing capability value not add_role or remove_role
You can create new roles using the command add_role.
add_role( 'custom_role', 'Custom Subscriber', array( 'read' => true, 'level_0' => true ) );
To modify an existing role you would need to remove it first and then add it back in.
remove_role( 'custom_role' );
add_role( 'custom_role', 'Custom Subscriber', array( 'read' => true, 'level_0' => true ) );
Be aware that modifying the capabilities array and re-executing add_role() will not necessarily update the role with the new capabilities list. The add_role() function short-circuits if the role already exists in the database.
I'am using ionic 3 and firebase 4.5.2 to make an application. I have a project in firebase and I would like to add and delete some values in my list "shoppingItems". I can now retrieve the list view and add items.
Screen of my database
My problem I can't remove a task because the $key of my value is undefined.
I get my list like this :
My values are contained in my variable result ( is an array of the object item: which contain 2 string the value and the key).
Thank's
What version of angularfire2 are you using? I've been attempting to learn Angular and in running through a CRUD tutorial while running on angularfire2 v5.0, I discovered that valueChanges() does not return any metadata.
The following information is gleaned from the angularfire2 documentation located at https://github.com/angular/angularfire2/blob/master/docs/version-5-upgrade.md
Calling .valueChanges() returns an Observable without any metadata. If you are already persisting the key as a property then you are fine. However, if you are relying on $key, then you need to use .snapshotChanges() and transform the data with an observable .map().
The documentation does provide an example as well.
constructor(afDb: AngularFireDatabase) {
afDb.list('items').snapshotChanges().map(actions => {
return actions.map(action => ({ key: action.key,...action.payload.val() }));
}).subscribe(items => {
return items.map(item => item.key);
});
}
Hopefully, you've discovered the solution by now. But I thought I'd drop this here in the event someone else finds your post.
How to get support for dot notation/nested objects in backbone model. The plugins that are available are buggy and wondering if backbone would ever support
person = { name : {first: 'hon',last:'son'}}
model = new Backbone.Model(person)
model.get('name.first')
model.set('name.first','bon')
There are two plugins to get the job done:
Backbone Nested
Backbone Deep Model
Both handle getting and setting attributes and change events for dot notation.
I did that if i were you:
var nameObj = model.get('name')
nameObj.first = bon
model.set('name', nameObj)
