Read-only & non-realtime mode activated to improve browser performance
Message pops up in my project and I'm unable to delete the nodes as well
Also I read this https://groups.google.com/forum/#!topic/firebase-talk/qLxZCI8i47s
Which states :
If you have a lot of nodes in your Firebase (say thousands), we need to create a new element for each node and modern browsers simply have limitations of how many DOM elements you can add to a page
It says:
To resolve this problem, don't load your Firebase Dashboard at the root of your Firebase, but instead load it lower down in the hierarchy
I do not get what it means
How do I get back to my Realtime Dashboard?
If you want to delete a high level node when this is activated, I recommend doing this.
Open up a text editor and type in { }. Save this file as "blankJSON.json".
Go to high level node you want deleted and select it, once it opens up and shows you all the nodes that need to be removed, select the three bars at the top right and select "Import JSON", (It would be safe to first "Export JSON" If you don't have backups, in case you make a mistake here). Import the JSON file we created earlier titled "blankJSON".
This will delete all of the data inside.
Once again, I highly suggest you make a backup before doing this, It's extremely easy to make a backup and also it is much easier than you would think to upload this blankJSON to the wrong node and then erasing a bunch of important data.
When it detects that it's downloading too many nodes from your database, the Firebase Console stops using real-time mode and switches to read-only mode. In this mode it requires less work from the browser, so it is more likely that the browser will stay performant.
To get back to realtime mode, you have to go to a location that has fewer nodes. So say that you start loading the database at the root, that means that "pseudo address bar" at the top of the data tree will say:
https://<your-project>.firebaseio.com/
And then will show the list of items. Now click on the URL in that pseudo address bar and change it to:
https://<your-project>.firebaseio.com/<one-of-your-keys>
And hit enter. The data tree will reload with just the node from one-of-your-keys and down and will likely switch to realtime mode again.
Every node key in firebase is a link, you can open a sub-node in a new tab and then edit that sub-node and its children.
Right click on a sub-node you want to edit or delete
Select open link in a new tab
Edit the sub-node in the new tab
1) Click on the Node you want to mass delete
2) Import an empty .json file (just containing curly braces, {} )
3) The node value will be set to null, in other words it is deleted or rather overridden with an empty node!
What you can do is to have an OnClickListener and call the remove value method to your DatabaseReference, like this:
mCart.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
mDatabaseReference.removeValue();
}
});
I have the same problem... I'm a bit surprised because I though Firebase could easily scale to support huge amount of data (example million users, etc.).
I have a node with 80000 sub-nodes (each object has his own push-id) and I cannot delete or perform any action on it because the real-time doesn't work in Firebase console.
I think the only way to udate or delete the data it's to do it via JAVA code :(
Multiple times trying to load the specific keys can be tiresome. There is a python library that could do this for you easily.

I needed to delete a lot of keys and this helped me do that in one go.
What I do is export the entire tree, edit/add the node I want using an editor, then import the JSON and overwrite the previous node/tree. Problem solved! Risky though 😁
I am running a loop where if condition met to select check box. I am unable to to do select multiple check boxes. It select first check box then run loop again but doesn't select next check boxes where condition are met.

To give some insight into what you're probably experiencing - Automation Anywhere object cloning basically operates like Javascript's getElementById in that it locks onto the first available item that meets the criteria you set forth in the object cloning parameters. There is no way to populate an array with these items like Javascript's getElementsByClassName might do.
This is interesting because if there are multiple items on the page that you're trying to work with and object cloning, by default, sets parameters that those items share, you'll only ever be able to interact with the first one.
I would suggest looking into additional parameters that distinguish each check box using Chrome's inspector or the other properties object cloning makes available to select.
For a tag system, when entering a new item, I'd like the user to start typing a letter or two and see possible tags...similar to how SO tags work on the website i.e. Ajax.
Is there a way to do this on IOS?
Basically the Add Item screen has some empty text fields where you put the name etc.
I'd like to have an additional empty field where as you enter letters you see possible tags appear below and can then select one to tag the item.
The tags would be served from an entity or table so there would have to be a call to core data to supply them based on the letters typed.
Do I have to implement a full blown tableview to do this? Or is there a way to make the possible tags show up below the textfield box.
Thanks for any suggestions.
You could try a third party development in order to make what you want. In a recent project I have used this one:
https://github.com/EddyBorja/MLPAutoCompleteTextField
One of our clients has a website that uses a lot of TreeListEx type field. By default, when an item is selected and moved over to the right side in the TreeListEx editor, the selected element is added to the bottom of the list on the right. The editors for this client would like to have this changed so that the element is added to the top of the list on the right.
For this I tried to look in the Shell folder at Treeview.js and Treelistexeditor.js. But I could not figure where to make the change.
In the TreeListExEditor.js file, look at the scSetMastersType.prototype.moveRight() function. In a loop it calls selected.appendChild(opt) which you may want to change to prepend the option. This would require a bit of JavaScript hackery on your part.
Perhaps start with a typeof(selected) to see what it is. I assume an array. If so, maybe do this:
Reverse the original array
Append your new item at the end of the revered data
Reverse it again to back to normal. Now your new option is at the beginning
Again, because this is JavaScript, there are plenty approaches you can take.
Say I make a work item in TFS. Then I make a change and update the text in the History tab (then save).
Using the TFS API, how can I get that text?
I would have thought it would have been in the History string for last item in the Revisions collection on the work item. (Because to set the string via the API you can use History on a normal work item.) However, in the Revisions array, all the work items are showing up as having History empty.
Any ideas on how I can get this string?
Check this blog post out: http://blogs.msdn.com/b/aaronbjork/archive/2011/01/10/programmatically-reading-work-item-comments.aspx
It’s a simple operation, but it might not be clear at first unless you discover that you need to loop through the collection of Revisions of the work item in order to view those comments.
You can get any of the basic tfs fields via aaronbjork's link and change it to use
Field f = r.Fields.TryGetById(1); or Field f = r.Fields["Title"]
title = 1
description = 52
the list of names and Ids is in the CoreField enumeration (only for non-custom fields)
