Unable to pass args to context.job_queue.run_once in Python Telegram bot API

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 18:39

A 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 which JobQueue 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 whole context argument of search_msgs. Just do context.job_queue.run_once(..., context=chat_id,...)
if you want to pass both the chat_id and context.args you can e.g. pass them as tuple:

Firebase, why addValueEventListener won't get triggered?

Asked 2021-Jun-15 at 14:40

I need to get the value of another child in my Firebase database inside addChildEventListener but addValueEventListener won't get triggered. Meaning that user_name_list will always be empty. How Can I solve this issue? Thanks!

Answered 2021-Jun-15 at 14:40

The problem is not so much that your ValueEventListener isn't getting triggered, but that you call list_fonct before that happens.

I'll include some links at the bottom to learn more about this, but for now the simple fix is to move the call to list_fonct into the onDataChange that is called one the user data is loaded:

Problem with RecyclerView and Navigation Drawer

Asked 2021-Jun-15 at 13:55

I'm doing a Group Chat with Firebase and currently I'm using a RecyclerView to display chat messages and I'm having a problem. When you open the app in the fragmented home and you go to chat activity and start chatting (adding elements to recycler view) all goes fine. But, when you go via the NavigationDrawer to another fragment and get back to the chat fragment using again this Navigation Drawer. When you add one element in the chat it appears all in the blank it just displays the last message. Anybody knows why does this happens?

Here I leave the RecyclerView Adapter Code:

Answered 2021-Jun-15 at 13:55

To solve your problem you can just remove the OnResume method because you are initializing the array every time you change between fragments and that is the problem.

After div is expanded, no other buttons work in that vertical space

Asked 2021-Jun-15 at 13:20

I have a tab button that handles the chatbox functionality. By default it is closed and when clicked, expands into the chat box. When it is closed all the buttons around it work as intended, however, when expanded the buttons above it can no longer be clicked like there is a invisible div over them.

Here I will provide the pictures of what I am describing and the corresponding code.

Your #olark-box-wrapper is a div with position:absolute; top: 0; height:100%; z-index:9999999999; ... no wonder it's taking up the full height of the right window area on top of everything else. And even though it's a transparent div, mouse clicks are handled by the event handlers of that div, not by those of the elements below it.

You could add pointer-events: none; to that div, making it "transparent" to user interaction. You may have to add pointer-events: visible; to its childs, to avoid the pointer-events: none; attribute being inherited by the children.

Alternatively, you could change the layout so that the #olark-box-wrapper is exactly the same height as its children.

One note about your choice of z-index: this number might be a bit too high, see Minimum and maximum value of z-index? (tl;dr: keep it in the range of a signed 32-bit number).

All of your files are inside frontEnd folder. Like in here:

Also you don't serve static files anywhere in your code. It should be something like in the docs:

How to create query for chat app groups with only one address as a parameter?

Asked 2021-Jun-15 at 07:54

Good day everyone, I am currently struggling with writing mysql query which should make chat group from messages. App which I am making is taking data from other service, so it's not up to me to also manage chat groups, I need take this info from messages themselves.

My table of messages looks like this:

id sendAddr receiveAddr lastMessage text read 1 Ccbbd6uUZF2GD5wE5LEfjGPA3YWPjoLC6P CMKovgETx2oYxhoYKAeSakmipBjbmQ9ZHF 2021-06-02 12:57:39 test3 0 5 Ccbbd6uUZF2GD5wE5LEfjGPA3YWPjoLC6P CMKovgETx2oYxhoYKAeSakmipBjbmQ9ZHF 2021-06-02 13:00:44 test3 0 7 CMKovgETx2oYxhoYKAeSakmipBjbmQ9ZHF Ccbbd6uUZF2GD5wE5LEfjGPA3YWPjoLC6P 2021-06-10 23:13:59 testVPS 0 8 CMKovgETx2oYxhoYKAeSakmipBjbmQ9ZHF CYfMNQ62u1qwhCBqXzcmeJ8D9j4Yc1Pwef 2021-06-10 20:03:59 neco 0 9 CYfMNQ62u1qwhCBqXzcmeJ8D9j4Yc1Pwef CMKovgETx2oYxhoYKAeSakmipBjbmQ9ZHF 2021-06-10 21:03:59 test 0

My only input data which I sent from my mobile app is receiveAddr so I need to add this to group anything which containes address in either sentAddr or receiveAddr, here is representation of what I want to achieve

user otherParticipant unread lastMessage text CMKovgETx2oYxhoYKAeSakmipBjbmQ9ZHF Ccbbd6uUZF2GD5wE5LEfjGPA3YWPjoLC6P 5 2021-06-10 23:13:59 testVPS CMKovgETx2oYxhoYKAeSakmipBjbmQ9ZHF CYfMNQ62u1qwhCBqXzcmeJ8D9j4Yc1Pwef 1 2021-06-10 21:03:59 test

It needs to have latest text counted amount of 0 in read column and lastMessage which is time of last message

I came up with something which sort of works if the user of the mobile app would be just receiving messages, which would be this:

SELECT sentAddr, COUNT(IF(campus.messages.read = 0, 1, NULL)) as unread, max(receiveTime) as lastMessage, max(text) as text FROM campus.messages WHERE (SELECT max(receiveTime) FROM campus.messages) AND receiveAddr = 'CMKovgETx2oYxhoYKAeSakmipBjbmQ9ZHF' GROUP BY sentAddr, receiveAddr

But sadly that does not get me a text from the latest message and not even taking into account that if the same user send some message, it shows as different group, which is not really helpful. I also came up with something which groups sendAddr and receiveAddr into one group no matter if it's on sending or receiving side:

GROUP BY CONCAT(LEAST(receiveAddr,sentAddr),' ', GREATEST(receiveAddr, sentAddr))

However in that case I can't with this added to upper query, it does not retrieve latest text, which is useless. So is there any chance of doing this with one query, no matter how long and convoluted it would be? And just to remind, only input data is user's address, which can be either sending or receiving address from the table. So is there any solution to this?

Version of the mysql database is 8.0.25

(You can skip this part if you already downloaded GitHub Respoitory and understand how to structure Rust application.). If you have tested code at ws-rs-html-example before you read on, you should have found that a single Rust(.rs) file does everything to render html, serve file, and exchange messages. It may be a decent single file example but it will be difficult to build more complicated app later. Therefore, we will pass its role to serve files to Rocket web framework. (I prefer it for it has many examples but you may use whatever framework.). We can start this from our Cargo.toml file like the code snippet below or use $cargo add ws-rs rocket.(You can visit cargo-edit page for this command). Nothing complicated for our Cargo.toml, What we need is to notify Rust that we need Rocket to serve our files such as HTML file to work as socket client, CSS, JavaScript, images etc at webpage. Then, ws-rs crate to work as socket server to handle chat messages. (If you are not familar with .toml files, you may think it is similar to package.json in JavaScript). Then we will build main.rs file first to be starting point for our Rust app.(Please, refer to the repository I gave before whenever you have doubts.). The major part of the Rocket relevant code will be the boilerplate if you want to write minimum webpage with it. So you don't have to understand all at once. But the important points here are. The part of the code snippet above includes. They are to serve routes and init your app with them. The important part here will be static_files and ws_rs. When you see the source code for static_routes first,. It is just to serve every files in static folder. You can just copy and paste it when you need to serve every files in static folder. (You can use simplified API in newer version of Rocket if you want.). for ws_rs route, important part is. and it is to serve HTML files for chat app. The file will help users to connect socket and have their separtate data with JavaScript and brwoser API later. We will learn how to do that in the last part of this post. You can refer to Steadylearner Chat and Rocket Documentation for more information.
We use thread to separate chat server and not to affect(break) the main server that manages your website(It is Rocket here)
You can assign .stack_size(83886 * 1024) here if you want to be serious with your chat app later.(You can search "How many resources chat app need" at your search engine.)
