@curiouspaul1 Amazing job, really! I was wondering about further development. Do you have any post I could look into?

Curious Paul • Apr 8 '22 • Edited

thanks for the kind words,
any post regarding what would you like me to help you with

@curiouspaul1 I tried to modify and use your Bot in my university so students can sell and buy things.
So, a few things I wish you could show/teach:
Divide posts/ads into categories but not businesses.
Also, I noticed that when fetching posts/ads from the databases sometimes it fails because, perhaps the user added unnecessary space or capitalization error (i tried to put a bunch of lower().strip() everywhere)
In addition, it would be amazing if SME and Customer both had the same functionality (both can buy and sell).
And I kinda failed to add Back buttons everywhere, but managed to add Exit button (just used you /cancel function)
Lastly, some buttons make require to be pressed two times, do you know why?

The bot: @ucaStudentStore_bot

hmm, thanks a lot for pointing all of these out, I will work on them and once an upate is ready, i'll let you know

Curious Paul • Apr 20 '22

you're also welcome to join me in implementing these, i see you;ve forked the repository already. Btw there's an option to filter post/ads by category already.

Hello. I rewrote your main code and when I run the code, it says the following:
& C: /Users/maxpy/AppData/Local/Programs/Python/Python39/python.exe
d: /Plmenno/main.py
File "", line 1
& C: /Users/maxpy/AppData/Local/Programs/Python/Python39/python.exe
^ d: /Plmenno/main.py

SyntaxError: invalid syntax.
What should I do?

Curious Paul • Jun 11 '22

Hi! I have problem when I try upload an image using Cloudinary, I don't know what happen. This is my code:

def add_media(update, context):
  send_photo = upload('http://res.cloudinary.com/demo/image/upload/couple.jpg')

The console show:

2021-07-15 14:01:44,494 - telegram.ext.dispatcher - ERROR - No error handlers are registered, logging exception.

    filename, data = value

Does anyone have any idea what is going on?

Curious Paul • Jul 15 '21

Hi, this doesn't seem like the code i wrote in the demo, for this article, however this doesn't look like the code to upload an image to cloudinary looks like. You might want to check the docs or use the one i wrote on the product_info method in handlers.py from the tutorial.

Álvaro Göede Rivera • Jul 15 '21 • Edited

I get the same problem when doing the demo, that's why I simplified it.

def add_media(update: Update, context: CallbackContext):
  logger.info(f"El usuario {update.effective_user['username']}, subió foto")
  quote = context.user_data["new_quote"]
  photo = context.bot.getFile(update.message.photo[-1].file_id)
  file_ = open("product_image", "wb")
  photo.download(out=file_)
  send_photo = upload("product_image", width=200, height=150, crop='thumb')

dp.add_handler(ConversationHandler(
  entry_points = [CommandHandler("new", handlers.start)],
  states={
    handlers.QUOTE: [
      MessageHandler(
          Filters.all, handlers.add_quote
      )
    ],
    handlers.MEDIA: [
      MessageHandler(Filters.photo, handlers.add_media)
    ]
  },
  fallbacks=[CommandHandler('cancel', handlers.cancel)],
  allow_reentry=True)
)

The console show the same error:

ValueError: not enough values to unpack (expected 2, got 1)

I know the error is upload because when I remove it the error does not appear.

Curious Paul • Jul 15 '21

I see, do you add caption to the image when you test it though.?

Álvaro Göede Rivera • Jul 15 '21

Could you check my code and see if there is something I am doing wrong?

github.com/alvaaz/telegram_bot

I would really appreciate it

Curious Paul • Jul 15 '21

oh great!, thanks for making this easier I'll take a look

Cant seems to solve this error while running the Main.py

Traceback (most recent call last):
File "C:\Users\ACER\Desktop\Bot\Bot\main.py", line 35, in
main()
File "C:\Users\ACER\Desktop\Bot\Bot\main.py", line 16, in main
entry_points=[CommandHandler('start', handlers.start)],
NameError: name 'handlers' is not defined. Did you mean: 'handler'?

Curious Paul • Dec 6 '21

did you rename the "handlers.py" file

pradiepp • Dec 7 '21

No, its 'handlers.py' only.

prodplug • Dec 1 '21

File "\main.py", line 9, in
updater = Updater(token=TOKEN, use_context=True)
File "\updater.py", line 237, in init
raise ValueError('token or bot must be passed')
ValueError: token or bot must be passed

any way to fix this (removed directory for privacy purpose)

this is when i enter python main.py

Curious Paul • Dec 2 '21

You have to replace "TOKEN" with the actual token that you got from the telegram Bot-father and use that instead, i just put "TOKEN" as a placeholder

BalighMehrez • Jun 13 '21

Awesome

Just wanted to notify you forgot to define the market on choose method
