i want to pass pk using react to django

like this when using only django Add comment

but i dont know how to pass pk using react template!!

this is my django models.py

I have a script that changes the Windows background image considering the current time of the day (day or night). I wanted to make this script scalable in order to be used on another computer without any change in the code.

I am parsing some interestingly formatted data from https://raw.githubusercontent.com/QuantConnect/Lean/master/Data/market-hours/market-hours-database.json

It contains a snippet (removing some days) as below:

I made navigation which is working in html and css, but when I added to it react it didn't work and also, I'm Unable to add script in file also but it didn't work. I used a react helmet but it also didn't help me. In-fact when I added the bootstrap navbar it also didn't help me. As I'm a facing problem when I make it to px below 800 it shows the hamburger menu option but when I click on it doesn't show the menu . One thing more when it always shows the home menu while on low px

this is my JSX code

I need to set expire date of product as present date till midnight as shown below in UTC format.

"2021-05-28T23:59:59Z"

How i can write this in C#.

I'm not sure if the title makes sense, it was the best I could come up with, so here's my scenario.

I have an ASP.NET Core app that I'm using more as a shell and for DI configuration. In Startup it adds a bunch of IHostedServices as singletons, along with their dependencies, also as singletons, with minor exceptions for SqlConnection and DbContext which we'll get to later. The hosted services are groups of similar services that:

1. Listen for incoming reports from GPS devices and put into a listening buffer.
2. Parse items out of the listening buffer and put into a parsed buffer.

Eventually there's a single service that reads the parsed buffer and actually processes the parsed reports. It does this by passing the report it took out of the buffer to a handler and awaits for it to complete to move to the next. This has worked well for the past year, but it appears we're running into a scalability issue now because its processing one report at a time and the average time to process is 62ms on the server which includes the Dapper trip to the database to get the data needed and the EF Core trip to save changes.

If however the handler decides that a report's information requires triggering background jobs, then I suspect it takes 100ms or more to complete. Over time, the buffer fills up faster than the handler can process to the point of holding 10s if not 100s of thousands of reports until they can be processed. This is an issue because notifications are delayed and because it has the potential for data loss if the buffer is still full by the time the server restarts at midnight.

All that being said, I'm trying to figure out how to make the processing parallel. After lots of experimentation yesterday, I settled on using Parallel.ForEach over the buffer using GetConsumingEnumerable(). This works well, except for a weird behavior I don't know what to do about or even call. As the buffer is filled and the ForEach is iterating over it it will begin to "chunk" the processing into ever increasing multiples of two. The size of the chunking is affected by the MaxDegreeOfParallelism setting. For example (N# = Next # of reports in buffer):

• N3 = 1 at a time
• N6 = 2 at a time
• N12 = 4 at a time
• ...

• N6 = 1 at a time
• N12 = 2 at a time
• N24 = 4 at a time
• ...

• N12 = 1 at a time
• N24 = 2 at a time
• N48 = 4 at a time
• ...

• N24 = 1 at a time
• N48 = 2 at a time
• N96 = 4 at a time
• ...

This is arguably worse than the serial execution I have now because by the end of the day it will buffer and wait for, say, half a million reports before actually processing them.

Is there a way to fix this? I'm not very experienced with Parallel.ForEach so from my point of view this is strange behavior. Ultimately I'm looking for a way to parallel process the reports as soon as they are in the buffer, so if there's other ways to accomplish this I'm all ears. This is roughly what I have for the code. The handler that processes the reports does use IServiceProvider to create a scope and get an instance of SqlConnection and DbContext. Thanks in advance for any suggestions!

I'd like to serialize a std::chrono::local_time by sending it's time_since_epoch().count() value. My question is how is a non-C++ receiver supposed to interpret that value? Is it the actual number of ticks since the epoch at local midnight (1970-01-01T00:00:00)? What about daylight saving time changes? Is the time_since_epoch() bijective with the wall clock time? That is, can there be two values of std::chrono::local_time::time_since_spoch() that represent the same wall clock/calendar time?

I cannot find detailed information about the interpretation of std::chrono::local_time::time_since_spoch() at the usual places: cppreference, the latest C++ standard draft, or Howard Hinnant's date library documentation.

'Why even serialize a std::chrono::local_time?', you may ask. Well, a use case would be a building automation system that must perform a certain task at a given local time on a special day, regardless of timezones or daylight saving time. For example, "turn off the lights at 20:00 local time on Earth Day, 2021 (April 22).

EDIT: 'Why not serialize it as an ISO8601 date/time (without any offset), you may ask?'. I want to serialize it as a compact number using a binary protocol, such as CBOR.

I'm using EF Core with .NET 5.0 and SQL Server Express. Basically I'm wondering if it generated a buggy SQL query or if my code is buggy (probably :D). I provided a mre at the bottom of the question, but hopefully the problem becomes evident from the data I've collected (I've already asked a similar question, but felt that it needed a complete overhaul)

I have a record and a DbContext like the following. It's stripped down to the important property Moment, which must be of type DateTimeOffset (company guideline).

I have a daily scheduler sequential scenario that needs to run every midnight:

1. Check_Tenant_Expiry and Get its return value (true/false)
2. Run_Daily_Report (pass the returning value from Check_Tenant_Expiry)

I expect to do Check_Tenant_Expiry and after it completed it will continue with Run_Daily_Report, I use the code below
