Recently I wrote code that should forward every message from a certain user to all groups that I joined but it doesn't. Here my code:

        for message in client.iter_messages('aliakhtari78'):
        try:
            dialogs = client.get_dialogs()
            for dialog in dialogs:
                id_chat = dialog.message.to_id.channel_id
                entity = client.get_entity(id_chat)
                client.forward_messages(
                    entity,  # to which entity you are forwarding the messages
                    message.id,  # the IDs of the messages (or message) to forward
                    'somebody'  # who sent the messages?
                )

        except:
            pass

in this code first I take every message which send to me by 'aliakhtari78' and then get entity of the groups that I joined to and in the end it should forward the message to all groups but it doesn't, I check my code and replace the entity with a user entity and it worked and I know the problem is because of entity, but I cant find out what is my problem. In addition, I'm sorry for writing mistakes in my question.

In order to send messages to any entities in Telegram, you need two pieces of information:

  1. the constant unique ID of the entity (It's an integer. It's NOT username string)
  2. the access_hash which is different for each user for each entity

You can only pass @username to client.get_entity, and Telethon automatically resolves the @username to an entity with id and access_hash. That's why it works when you change your code like that. However, in your code, you have passed channel_id (which is the constant unique ID of the entity) to client.get_entity, not username.

Note that client.get_dialogs returns entities along with dialogs. You have just ignored the entities! This is how you can get an array of all entities:

dialogs, entities = client.get_dialogs()

Then simply pass the corresponding entity from the entities array to client.forward_messages.
