QUESTION
I'd like to be able to extract the task dependency graph for a celery AsyncResult/Signature. My AsyncResult/Signature may be a complex chain/group/chord. I'd like to extract the graph of task_id from parent/children AsyncResults and serialize it so that I can reconstitute the AsyncResult from task_id string at a later date.
I suspect this output would come from traversing the AsyncResult.children or AsyncResult.parent tree of tasks, but wanted to see if anything in celery already existed for this without having to write my own traversal code.
I'd like an output something roughly akin to:

Answered 2022-Apr-03 at 17:49Looks like lots of the tools to use are discussed in this answer on GitHub.
Main tools:
Async/GroupResult.as_tuple()gives a serialized tuple representation of the entire dependency graph. Used in conjunction withcelery.result.result_from_tuple(tuple_representation)to rehydrate anAsync/GroupResultfrom the tuple serialization.my_group_result.save()if trying to accessGroupResultobjects in the future from a single id. This saves the tuple representation to the bckend. Used in conjunction withGroupResult.restore(group_id). Note that it does not capture the parents of either the group or its childrenAsyncResults.
If you want to save these results to a database so that they can be fully retrieved at a future date with just an id the following methods provide that:
QUESTION
Thanks in advance for reading. I'm working on my final project for CS50W which involves working with a series of local audio files (user cannot upload additional files at this time). The issue occurs when I try to populate an src attribute with the file. I have two URL paths which deal with accessing these files: new/ and edit/int:id. When I access the audio files in new/, it works as intended and I can play the file from the tag. However, when I try to access the files in the edit/int:id path, I get this error:
GET http://localhost/edit/8/media/Aminor_Ipi3udk.mp3 net::ERR_ABORTED 404 (Not Found)
I am relatively new to coding (just did CS50x and then started CS50w) and I don't understand why I'm getting this error or how I can fix it - I'm doing the same thing for both paths and yet it only works in one of them. I would be grateful if someone could help me to remedy this or at least point me in the direction of understanding why this is happening.

...ANSWER
Answered 2022-Mar-31 at 19:39The quick fix here is to change media/{{ chord.file }} to /media/{{ chord.file }}. However, you shouldn't be manually creating this path in the first place. I think you can do {{ chord.file.url }} instead. Here I'm assuming that chord is a model object with a FileField named file. I suggest you check the documentation for FileField to verify this and understand it better.

ANSWER
Answered 2022-Mar-14 at 16:49The menu toggle button is outside the element you are attaching the outside click listener to, so when you are trying to close the menu the toggle callback and the checkIfClickedOutside handlers are cycling the isMenuOpen state.
Wrap both the menu button and the menu in a div for the ref to be attached to. There is also no reason really to check if isMenuOpen is true in the checkIfClickedOutside handler. If isMenuOpen is already false, enqueueing another state update to set it false is generally ignored by React. This allows you to remove it as a dependency.

In my home page, I have a search bar with a button at the top of my page and I displayed all my songs using their title from my database underneath that.
The search bar is working fine since every song title I typed, it took me to the correct detail page.
I'm just wondering how can I also click on the song title and take me to each song detail page.

In my Gatsby typescript project, the types defined in the "*.d.ts" files are always unrecognized and is always highlighted as an unknown type.
But when the respective type file is opened in a new tab, the respective lint errors are abscent.
How to make sure VS CODE auto scans and identifies type files in the project folder without having to open them manually everytime ?

Answered 2022-Mar-04 at 21:44You should put everything related to the Chord class into the Chord.ts file. d.ts files are used to define types for JavaScript modules which is not what you have here.
In your index.tsx file you can then import the Shapes type like so:
QUESTION
I want to find a Powershell version of the bash edit-and-execute-command widget or the zsh edit-command-line widget.
Short commands get executed directly on the command-line, long complicated commands get executed from scripts. However, before they become "long", it helps to be able to test medium length commands on the command-line. To assist in this effort, editing the command in an external editor becomes very helpful. AFAIK Powershell does not support this natively as e.g. bash and zsh do.
I am new to Powershell, so I'm bound to make many mistakes, but I have come up with a working solution using the features of the [Microsoft.Powershell.PSConsoleReadLine] class. I am able to copy the current command-line to a file, edit the file, and then re-inject the edited version back into the command-line:
ANSWER
Answered 2022-Feb-19 at 12:16This code has some issues:
- Temp path is hardcoded, it should use
$env:tempor better yet[IO.Path]::GetTempPath()(for cross-platform compatibility). - After editing the line, it doesn't replace the whole line, only the text to the left of the cursor. As noted by mklement0, we can simply replace the existing buffer instead of erasing it, which fixes the problem.
- When using the right parameters for the editor, it is not required to create a job to wait for it. For VSCode this is
--wait(-w) and for gvim this is--nofork(-f), which prevents these processes to detach from the console process so the PowerShell code waits until the user has closed the editor. - The temporary file is not deleted after closing the editor.
Here is my attempt at fixing the code. I don't use gvim, so I tested it with VSCode code.exe. The code below contains a commented line for gvim too (confirmed working by the OP).

Answered 2022-Jan-19 at 07:40There are several issues here:
- The main problem is that you have to scroll the element you want to click on into the view. Your default initial screen height presents 8 rows while to click on 9-th row and more you have to scroll that element first into the view.
- You could set driver window to better dimensions, this will show you more screen, however you will still have to scroll, but after 15 elements.
- You should improve your locators.
- You should not mix up

I have installed the Ursina game engine recently and I am getting started with it, but as I write a basic program it gives me a traceback contradicting some built in programs in ursina and ending with a Filenotfound Winerror 3 pointing to a music folder which has nothing to do with python, I double checked if Ursina is installed properly but it was not the case, and I checked the folder it is pointing to which as expected contained only music. Is there a problem with the path of the engine? I hope you can answer me. Anyway here is the code:
...ANSWER
Answered 2022-Jan-04 at 17:12Since you put your script directly on the Desktop, you made that your project folder. So when you try to load a model, ursina will search all your files and folders on the desktop for a file matching that name.
Move your scripts and relevant assets into a separate folder.
