FirebaseDatabase display a single value from a single user


FirebaseDatabase display a single value from a single user

Hope this helps Assuming that Users node is a direct child of your Firebase database root and 0x2s4Ft... is the uid of the logged in user, to get the value only from your Displayname field, please use the following code:
code :
FirebaseUser firebaseUser = firebaseAuth.getCurrentUser();
String uid = firebaseUser.getUid();

DatabaseReference rootRef = FirebaseDatabase.getInstance().getReference();
DatabaseReference uidRef = rootRef.child("Users").child(uid);
ValueEventListener eventListener = new ValueEventListener() {
    @Override
    public void onDataChange(DataSnapshot dataSnapshot) {
        String Displayname = dataSnapshot.child("Displayname").getValue(String.class);
        Log.d("Testing: ", Displayname);
    }

    @Override
    public void onCancelled(DatabaseError databaseError) {}
};
uidRef.addListenerForSingleValueEvent(eventListener);
Testing: Chrisharvz

Combine array values into a single value to display in a single column of a grid

may help you . You can't have an array as a single column
You should make it string in the Model, or have another property with the joined array:
code :
public class MyModel
{
    public string parentName {get; set;}
    public string[] childrenNames { get; set; }
    public string JoinedNames { get; set; }
}

loo[1] = new MyModel();
..
...
loo[1].JoinedNames  = string.Join("," loo[1].childrenNames);

@(Html.Telerik().Grid(Model)
.Columns(columns =>
{
    columns.Bound(o => o.parentName).Width(100).Title("Parent");
    columns.Bound(o => o.JoinedNames).Width(250).Title("Kids");
 }

fixed the issue. Will look into that further I am able to get to this point, and not sure how to print the result of the latest entry. I've a class called "Transaction" and multiple column, and hundreds of rows that is entered in different date and time. I'm only interested to display the latest entry from the class. Please help if you have any idea. thanks. , To get access to the objects that are returned, you can do this:
code :
if error == nil {
    let foundObjects: [PFObject] = objects!
    for object in foundObjects {
        print(object["city"])
    }
}
Why single-{slug}.php not calling in wordpress for single post display?

Why single-{slug}.php not calling in wordpress for single post display?

it helps some times Hey everyone I am facing trouble calling single-{slug}.php in wordpress when I am displaying a particular post. , Here is the correction
code :
single-{post-type}-{slug}.php – (Since 4.4) First, WordPress looks for a template for the specific post. For example, if post type is product and the post slug is dmc-12, WordPress would look for single-product-dmc-12.php.

help you fix your problem It seems model.getUserid() in mDatabaseUsers.child(model.getUserid()) is null which causes the NullPointerException.
Why it's null is hard to tell with the code you've provided, but you should be able to debug it.
Display child elements in a single row unless they overflow, then display a single column

Display child elements in a single row unless they overflow, then display a single column

Hope this helps I think this is not possible without JavaScript (because you need it to detect overflow). With that being said, you could base your solution around flexbox as it allows you to switch between row / column layout via single CSS property on your container element. Other option might be to switch between inline-block / block display on the children for example, but you would have to do that for all of them - that's why flexbox is better here. Example might look like this:
code :
const outer = document.querySelector('.outer')

if (outer.clientWidth < outer.scrollWidth) {
  outer.classList.add('direction-column');
} else {
  outer.classList.add('direction-row');
}
.outer {
  background-color: lightgrey;
  width: 500px;
  padding: 10px;
  display: flex;
  align-items: flex-start;
}

.inner {
  background-color: darkgrey;
  margin: 5px;
  flex: none;
}

.direction-row {
  flex-direction: row;
}

.direction-column {
  flex-direction: column;
}
<div class="outer">
  <div class="inner">Some text, blah</div>
  <div class="inner">Some text, blah blah</div>
  <div class="inner">Some text, blah blah blah</div>
  <div class="inner">Some text, blah blah blah blah</div>
  <div class="inner">Some text, blah blah blah blah blah</div>
  <div class="inner">Some text, blah blah blah blah blah blah</div>
</div>
