QUESTION
I am running the following in my React app and when I open the console in Chrome, it is printing the response.data[0] twice in the console. What is causing this?
...ANSWER
Answered 2021-Jun-16 at 02:48You have included fetching function in the component as it is, so it fires every time component being rendered. You better to include fetching data in useEffect hook just like this:

I'm trying to understand how parallelization works in Durable Function. I have a durable function with the following code:
...ANSWER
Answered 2021-Jun-10 at 08:44There are two approaches that are possible. The first is to use a suborchestrator for each job so that each suborchestrator handles just a specific job. Here is the docs for this approach https://docs.microsoft.com/en-us/azure/azure-functions/durable/durable-functions-sub-orchestrations?tabs=csharp Example from docs seem to be alike to yours.
The other is to use ContinueWith so that each job has its own "chain"

I've ran into problem getting UI lags when this line is running:
...ANSWER
Answered 2021-Jun-16 at 00:29I don't believe you can use SharedPreferences within an Isolate without support for MethodChannel / accessing platform-specific underlying OS frameworks on iOS / Android.
You would need to use FlutterIsolate or a similar package to provide that support.
chunhunghan has a good answer detailing this.
Alternatively, you could run the crypt.generateKeys()
by itself in your Isolate.spawn()
call and use the results after in a separate method accessing SharedPreferences
. (Assuming that crypt
package is also not relying on platform-specific code.)
QUESTION
Can someone help me investigate why my Chainlink requests aren't getting fulfilled. They get fulfilled in my tests (see hardhat test etherscan events(https://kovan.etherscan.io/address/0x8Ae71A5a6c73dc87e0B9Da426c1b3B145a6F0d12#events). But they don't get fulfilled when I make them from my react app (see react app contract's etherscan events https://kovan.etherscan.io/address/0x6da2256a13fd36a884eb14185e756e89ffa695f8#events).
Same contracts (different addresses), same function call.

Here's the code I use to call them in my tests

seems not right, you are currently trying to query on the url. Not on the query options. The following function should work.

QUESTION
I am new to rust and I was reading up on using futures
and async / await
in rust, and built a simple tcp server using it. I then decided to write a quick benchmark, by sending requests to the server at a constant rate, but I am having some strange issues.
The below code should send a request every 0.001 seconds, and it does, except the program reports strange run times. This is the output:
...ANSWER
Answered 2021-Jun-15 at 20:06You are not measuring the elapsed time correctly:
total_send_time
measures the duration of thespawn()
call, but as the actual task is executed asynchronously,start_in.elapsed()
does not give you any information about how much time the task actually takes.The
ran in
time, as measured bystart.elapsed()
is also not useful at all. As you are using blocking sleep operation, you are just measuring how much time your app has spent in thestd::thread::sleep()
Last but not least, your
time_to_sleep
calculation is completely incorrect, because of the issue mentioned in point 1.
QUESTION
I need a cloud function that triggers automatically once per day and query in my "users" collection where "watched" field is true and update all of them as false. I get "13:26 error Parsing error: Unexpected token MyFirstRef" this error in my terminal while deploying my function. I am not familiar with js so can anyone please correct function. Thanks.
...ANSWER
Answered 2021-Jun-15 at 16:13There are several points to correct in your code:
- You need to return a Promise when all the asynchronous job is completed. See this doc for more details.
- If you use the
await
keyword, you need to declare the functionasync
, see here. - A
QuerySnapshot
has aforEach()
method - You can get the
DocumentReference
of a doc from theQuerySnapshot
just by using theref
property.
The following should therefore do the trick:
QUESTION
One of my functions can cause a KeyError
error to be raised. This raises a CommandInvokeError
. However, there are other errors, like DivisionByZero
that can cause the CommandInvokeError
to be raised. I only know one way to handle errors and it's:
ANSWER
Answered 2021-Jun-15 at 19:52@cmd.error
async def cmd_error(self, ctx, error):
if isinstance(error, commands.CommandInvokeError):
if isinstance(error.original, KeyError):
await ctx.send("Error!")
QUESTION
I'm writing a Firebase function (Gist) which
Queries a realtime database ref (events) in the following fashion:
await admin.database().ref('/events_geo').once('value').then(snapshots => {
Iterates through all the events
snapshots.forEach(snapshot => {
Events are filtered by a criteria for further processing
Several queries are fired off towards realtime DB to get details related to the event
await database().ref("/ratings").orderByChild('fk_event').equalTo(snapshot.key).once('value').then(snapshots => {
Data is prepared for SendGrid and the processing is finished
All of the data processing works perfectly fine but I can't get the outer await (point 1 in my list) to wait for the inner awaits (queries towards realtime DB) and thus when SendGrid should be called the data is empty. The data arrives a little while later. Example output from Firebase function logs can be seen below:
10:54:12.642 AM Function execution started
10:54:13.945 AM There are no emails to be sent in afterEventHostMailGoodRating
10:54:14.048 AM There are no emails to be sent in afterEventHostMailBadRating
10:54:14.052 AM Function execution took 1412 ms, finished with status: 'ok'
10:54:14.148 AM
Super hyggelig aften :)
super oplevelse, ... long string generated

I'm probably mixing up my async/awaits because of the awaits inside the await. But I don't see how else the code could be written without splitting it out into many atomic pieces but that would still require stitching a bunch of awaits together and make it harder to read.
So, two questions in total. Can this code work and what would be the ideal way to handle this pattern of making further processing on top of data fetched from Realtime DB?
Best regards, Simon
