I'm trying to implement a DynamoDB get_item call using https://github.com/aws/aws-sdk-ruby/blob/0465bfacbf87e6bc78c38191961ed860413d85cd/gems/aws-sdk-dynamodb/lib/aws-sdk-dynamodb/table.rb#L697 via our Ruby on Rails app, dr-recommends.

From reviewing this DynamoDB CloudFormation stack that I wrote, I expect the following get_item call to work, so I'm a little lost as to how to proceed.

I found some code to iterate through arithmetic operators across a static, excecutable formula in Python:

If I have an async-function which contains an explicit return statement which returns a Promise, what will be the value of an await expression calling such a function?

Does the await resolve to the value given by the explicit return-expression of the async-function, or does it resolve to what that value resolves to in case it is a Promise?

I know there are already questions related to this topic on Stack Overflow, but I would just like a precise answer to this question: "Is it possible for an 'await' to resolve to a Promise?". Yes or No? Of course if you can also explain why or why not, that would be very helpful.

I need to be able to identify whether a given PCI device is express or non-express at runtime. One possible way to ID this is to get the Configuration space and check for an extended section. If the extended section exists then it's a PCIe card. Specifically i would check the first four bytes to see if they are 0x100 as the specification requires.

Is this the best way to validate what type of card is being used? Are my assumptions correct?

I have a Django model that has a NumberVal field which is models.FloatField().

Then I need to annotate the queryset objects like so .annotate(numberval_as_text=str(OuterRef("NumberVal"))) - the same value, but as a string except for the fact that this throws QuerySet.annotate() received non-expression(s): OuterRef(NumberVal) error which is clearly right but it demonstrates the point.

I need this because this annotation is followed by an extensive second annotation where I need this numberval_as_text in subquery filters.

Any hint would be appreciated.

I have a comma-separated string that I want to plug into a function as a comma-separated expression. Specifically, there are various functions that take ... as a parameter, and I want to have a method for converting comma-separated strings into a list of comma-separated parameters that can be 'injected' into the ... parameter in a function call. I tried using parse and eval as hinted at on this page, but I am still failing to get my function to work.

Below you see a reproducible example of what I am trying to do.

This works just fine

I have a tendency to align my code by adding whitespace in the following (unconventional) way.

Django==3.2

At a breakpoint I have such queryset:

I am building an integration with Express Session and I am trying to authenticate the user in a separate webhook. So I need a way to update the user session outside of the request since it would be a different request.

What I did is I passed the session ID to the new request, and use MongoClient to update the session in the database. I remember Express Session only stores the ID on the client-side and the data is store on the database, so I assume updating the database would do it. But that doesn't seem to be the case. I can clearly see that the session on MongoDB is all updated but I kept getting the outdated data in req.session.data.

Here's what I've done

So the first thing I tried is to use the req.session.reload() method like these:

Updating express-session sessions

change and refresh session data in Node.js and express-session

But it is still giving me outdated data as if the function did nothing (it did print out logs so I assume it did run).

I tried using this that uses store.get() method from Express Session but it is giving me undefined session.

Express load Session from Mongo with session_id

So as a last resort I use MongoClient to get the session data directly and update the session with the data obtained. I use async for the route handler and await the MongoClient to get the data. It doesn't wait for the await and just kept throwing undefined. I thought it's my code that's wrong but I am able to get user data with the code and it did wait for the MongoClient to get the data, but somehow it is not working for session data.

Here's part of my code:
