QUESTION
In the following code how can we pass the context.args
and context
to another function, in this case callback_search_msgs
ANSWER
Answered 2021-Jun-15 at 18:39A few notes:
- job callbacks accept exactly one argument of type
CallbackContext
. Not two. - the
job_kwargs
parameter is used to pass keywoard argument to the APScheduler backend, on whichJobQueue
is built. The way you're trying to use it doesn't work. - if you want to know only the
chat_id
in the job, you don't have to pass the wholecontext
argument ofsearch_msgs
. Just docontext.job_queue.run_once(..., context=chat_id,...)
- if you want to pass both the
chat_id
andcontext.args
you can e.g. pass them as tuple:
QUESTION
From "C++ Concurrency in Action" by Anthony Williams.
The author defines a thread_guard
class which, is passed a reference to a std::thread
upon construction, and upon destruction, attempts to join()
that same thread.
Here is the definition
...ANSWER
Answered 2021-Jun-14 at 09:16The explanation given isn't the most compelling reason (imo).
There should only ever be one thread_guard
for each thread. Making it uncopyable means that it is difficult to accidentally have two guards of the same thread.
The expected use case is that both the thread and the guard are automatic storage duration objects living in the same scope, with the guard joining the thread just before it is destroyed. There isn't a need to copy the guard

QUESTION
I'm stuck with this Telegram bot since couple of days. I'm trying to setup a bot which:
- Receives the keywords in
/search_msgs userkey
command from a TG group - Search in DB for that
userkey
and send back appropriate text back
I'm getting two errors
- None type object has no attribute args, in
callback_search_msgs(context)
, see code snippet - AttributeError: 'int' object has no attribute 'job_queue',
in search_msgs(update, context)
, see code snippet.
Telegram's official documents is way too difficult for me to read and understand. Couldn't find even one place where Updater, update, Commandhandler, context are all explained together with examples.
I'm not asking you to write a complete tutorial or do my work. But a brief explanation and fix to this code will be greatly appreciated.
...ANSWER
Answered 2021-Jun-07 at 14:42Let me first try & clear something up:
Telegram's official documents is way too difficult for me to read and understand. Couldn't find even one place where Updater, update, Commandhandler, context are all explained together with examples.
I'm guessing that by "Telegram's official documents" you mean the docs at https://core.telegram.org/bots/api. However, Updater
, CommandHandler
and context
are concepts of python-telegram-bot
, which is one (of many) python libraries that provides a wrapper for the bot api. python-telegram-bot
provides a tutorial, examples, a wiki where a lots of the features are explained and documentation.
Now to your code:
In
context.job_queue.run_once(callback_search_msgs, context=update.message.chat_id)
you're not tellingjob_queue
when to run the the job. You must pass an integer or adatetime.(date)time
object as second argument.in

I need to start sending notifications to a TG group, before that I want to run a function continuosly which would query an API and store data in DB. While this function is running I would want to be able to send notifications if they are available in the DB:
That's my code:
...ANSWER
Answered 2021-Jun-05 at 13:42There are a few issues with your code, let me try to point them out:
1.
def callback_msgs(): fetch_msgs()
You use callback_msgs
as callback for your job. But job callbacks take exactly one argument of type telegram.ext.CallbackContext
.

QUESTION
My databases are broken out into teams-games and user-games. Each team can play in multiple games (no limit) that have their own total_points
column. The team's total_points
are the sum of the user-games points
column. It is setup like this:
table: team_games
team_id game_id total_points 1 1 10 1 2 20 1 3 30 1 4 3table: user_games
user_id team_id game_id points 1 1 1 3 2 1 1 7 1 1 2 13 2 1 2 7 1 1 3 13 2 1 3 17 1 1 4 3 2 1 4 0My goal is to find each users sum of points in their teams top three scoring games. I am having trouble getting the top three scoring games and summing up the users scores for those. I have tried something like below where I limit the rows to 3 to get the top three games but can not get anything to work properly.
...ANSWER
Answered 2021-Jun-01 at 21:10You could use a CTE for this. Would be nice to have more data to see if this works for you. Need to determine your expected results if multiple games have the same top score, such as how to treat if four games are in top three scoring category. Would you want to just add up the four games then? If so, this should work. Also, may want to change the join to LEFT join, depending what you are trying to show.
QUESTION
I have a use-case where I'm building to a target "state":
...ANSWER
Answered 2021-May-28 at 18:28State
is a complete subset of Partial
, that is why State | Partial == Partial
.
The only way you can coerce the Partial
into State
is by explicit setting Required
or, using type-fest and setting SetRequired, "foo" | "bar">
(but this one implies that you can extract the keys from somewhere).
