kandi X-RAY | tree Summary
tree is a library for working with nested data structures. In a way, tree generalizes the builtin map function which only supports flat sequences, and allows to apply a function to each "leaf" preserving the overall structure. tree is backed by an optimized C++ implementation suitable for use in demanding applications, such as machine learning models.

QUESTION
I have prepare 2 tree view in separate iframe using jstree. The right tree view should control the left tree view. When user click one one the list in right tree view, the respective item folder will open and selected on left tree view. I can make it happen using div in single page. I control the left tree view using instance of left tree view in right jstree div var instance = $('#left').jstree(true);.
ANSWER
Answered 2021-Jun-16 at 03:07I had used document.getElementById('1').contentWindow.jQuery('#left').jstree(true); to get instance from iframe with id='1'. In order to listen to right iframe(with id='2') if any menu has been clicked, I used document.getElementById('2').contentWindow.jQuery('#right').on("changed.jstree",function(e,data){}). I get the instance of left iframe within this function. By using this instance, I has deselect previous selection, select current selection, and open children of selected menu.

I built an app using Django 3.2.3., but when I try to settup my javascript code for the HTML, it doesn't work. I have read this post Django Static Files Development and follow the instructions, but it doesn't resolve my issue.
Also I couldn't find TEMPLATE_CONTEXT_PROCESSORS, according to this post no TEMPLATE_CONTEXT_PROCESSORS in django, from 1.7 Django and later, TEMPLATE_CONTEXT_PROCESSORS is the same as TEMPLATE to config django.core.context_processors.static but when I paste that code, turns in error saying django.core.context_processors.static doesn't exist.
I don't have idea why my javascript' script isn't working.

Answered 2021-Jun-15 at 18:56Run ‘python manage.py collectstatic’ and try again.
The way you handle static wrong, remove the static dirs in your INSTALLED_APPS out of STATIC_DIRS and set a STATIC_ROOT then collectstatic again.
Add the following as django documentation to your urls.py

I am trying to use next-firebase-auth package to manage authentication in my next js app. Before messing around, I wanted to run the example. However, I could not find proper explanation for the fields required in the .env file.
Could you please explain what should be the values of following fields in local.env file here

QUESTION
I am trying to parse many XML test results files and get the necessary data like testcase name, test result, failure message etc to an excel format. I decided to go with Python.
My XML file is a huge file and the format is as follows. The cases which failed has a message, & and the passed ones only has . My requirement is to create an excel with testcasename, test status(pass/fail), test failure message.
...ANSWER
Answered 2021-Jun-15 at 17:46Since your XML is relatively flat, consider a list/dictionary comprehension to retrieve all child elements and attrib dictionary. From there, call pd.concat once outside the loop. Below runs a dictionary merge (Python 3.5+).

QUESTION
I have a question about how rebasing works in git, in part because whenever I ask other devs questions about it I get vague, abstract, high level "architect-y speak" that doesn't make a whole lot of sense to me.
It sounds as if rebasing "replays" commits, one after another (so sequentially) from the source branch over the changes in my working branch, is this the case? So if I have a feature branch, say, feature/xyz-123 that was cut from develop originally, and then I rebase from origin/develop, then it replays all the commits made to develop since I branched off of it. Furthermore, it does so, one develop commit at a time, until all the changes have been "replayed" into my feature branch, yes?
If anything I have said above is incorrect or misled, please begin by correcting me! But assuming I'm more or less correct, I'm not seeing how this is any different than merging in changes from develop by doing a git merge develop. Don't both methods result with all the latest changes from develop making their way into feature/xyz-123?
I'm sure this is not the case but I'm just not seeing the forest through the trees here. If someone could give a concrete example (with perhaps some mock commits and git command line invocations) I might be able to understand the difference in how rebase works versus a merge. Thanks in advance!

Answered 2021-Jun-15 at 13:22" It sounds as if rebasing "replays" commits, one after another (so sequentially) from the source branch over the changes in my working branch, is this the case? "
Yes.
" Furthermore, it does so, one develop commit at a time, until all the changes have been "replayed" into my feature branch, yes? "
No, it's the contrary. If you rebase your branch on origin/develop, all your branch's commits are to be replayed on top of origin/develop, not the other way around.
Finally, the difference between merge and rebase scenarios has been described in details everywhere, including on this site, but very broadly the merge workflow will add a merge commit to history. For that last part, take a look here for a start.

QUESTION
I have an object of class Employee (let us call it Alice), and want to create a copy of this object (let us call it Alice_again) such that if I change Alice, the properties of Alice_again also changes. Basically creating a copy of an object whose properties are bound to the original.
Edits
I am having two diferent ObservableCollection of Employee(Employee is User Control) and both contains same object Employee and I want to display each ObservableCollection once. For that I am using ItemsControl and I have binded ItemsSource of ItemsControl to these ObservableCollection and as I have read on this link that a given object may only be present in a given logical tree once, so I am trying to create a copy of object but I don't want to update both copies whenever there is an update.
...ANSWER
Answered 2021-Jun-15 at 10:22You do not need to create a copy.
Since the elements in the ItemsSource collection are not supposed to be Visuals, two or more source collections may contain references to the same objects.
Two different UI elements in the ItemTemplate of two ItemsControl would hence legitimately bind to the same data item object.
