I do not know much about asynchrony, I tried to turn for loops into async for, but now only
the first element of the generator is working, the rest are ignored. What is wrong with
this code?
async def get_requests(self, data, request_type):
for x in data:
r = [
'subscribe_on_model',
{
'collection': None,
'id': None,
'recursive': ''
}
]
r[1]['collection'] = request_type
r[1]['id'] = x
yield r
async def get_results(self):

await ws.receive()

async for bundle_request in bundle_requests:

b_request = [bundle_request]
await ws.send(b_request)

bundle_ids = b_response[0][1].get('lineCountryIds')

I am programming Telegram Login page with Flet Gui and Telethon module.

This is our CentralSystem.py
We have a LIVE charger configured to connect to our websocket
Ex - ws://HostName:Port/Charger Serial Number
As soon as the Charger is connected to our central system, it automatically sends us the following:
Charge point /D5200372001000010101 connected
INFO:ocpp:D5200372001000010101: receive message [2,"530","Heartbeat",{}]
Heartbeat
INFO:ocpp:D5200372001000010101: send [3,"530",{"currentTime":"2022-06-10T10:43:26Z"}]
INFO:ocpp:D5200372001000010101: receive message [2,"531","Heartbeat",{}]
Heartbeat
Issue 1 - We receive the heartbeat every 2mins but do not see anything for BootNotification and Status Notification when no vehicle is connected.
However, when the vehicle is connected, we do see a Status Notification and Heartbeats.
Issue 2 - Now, we have a mobile app that is built using Flutter which should allow us to enable "Remote Start Transaction". What is the best way to achieve this? Should we connect to the same websocket endpoint and call RemoteStartTransaction.

At first my discord bot doesn't work, in this code is erorr and i can't find it, and second is that it doesn't changing status, it was changing when you put just 2 text but when trying to put client.guilds it not
#tasks.loop( seconds = 12 )
async def changeStatus():
iterationPosition = 0
status = [f' on { len(client.guilds) } servers', '~help']
await client.change_presence(activity=discord.Activity(type=discord.ActivityType.playing, name=status[iterationPosition]))
iterationPosition = 0 if (iterationPosition is len(status) - 1) else (iterationPosition + 1)
#client.event
async def on_ready():
print( 'bot connected' )
changeStatus.start()
*Working code but with problem that he writes me answer to commands as many times as all servers he on
tasks.iterationPosition = 0
#tasks.loop( seconds = 5 )
async def changeStatus():
status = [f" on { len(client.guilds) } servers", "~help"]
await client.change_presence(
activity=discord.Activity(
type=discord.ActivityType.playing, name=status[tasks.iterationPosition]
)
)
tasks.iterationPosition = (
0
if (tasks.iterationPosition is len(status) - 1)
else (tasks.iterationPosition + 1)
)
#client.event
async def on_ready():
print( 'bot connected' )
changeStatus.start()
In your code you always assign 0 to iterationPosition at the start of loop, instead put it in "global" scope like this:
tasks.iterationPosition = 0
#tasks.loop(seconds=12)
async def changeStatus():
status = [f" on { len(client.guilds) } servers", "~help"]
await client.change_presence(
activity=discord.Activity(
type=discord.ActivityType.playing, name=status[tasks.iterationPosition]
)
)
tasks.iterationPosition = (
0
if (tasks.iterationPosition is len(status) - 1)
else (tasks.iterationPosition + 1)
)
I am trying to interject a username into the footer of a discord embedded message, that says who requested the command and I've tried varies things and I cant get it to work the way I want it to. Any help would be appreciated. I want it to go into the price command
#client.command(pass_context=True)
async def ping(ctx):
username = ctx.message.author.display_name
channel = ctx.message.channel
t1 = time.perf_counter()
await client.send_typing(channel)
t2 = time.perf_counter()
embed=discord.Embed(title="Pong at {username}".format(username=username), description='It took {}ms.'.format(round((t2-t1)*1000)), color=0xDA70D6)
await client.say(embed=embed)
#client.command(aliases= ['price', 'p'])
async def calc(quantity: int, itemA: str, itemB: str):
#itemAPrice = get_value(itemA)
#itemBPrice = get_value(itemB)
itemAPrice = items[aliases[itemA]]
itemBPrice = items[aliases[itemB]]
if itemAPrice and itemBPrice:
itemQuotient = itemAPrice/itemBPrice
itemBEquivalent = round(quantity * itemQuotient, 2)
embed=discord.Embed(title="Exchange Rate", description='{quantity} {itemA} is equal to {itemBEquivalent} {itemB}'.format(quantity = quantity, itemA = itemA, itemBEquivalent = itemBEquivalent, itemB = itemB), color=0xDA70D6)
await client.say(embed=embed)
elif not itemAPrice:
await client.say('No match found for ' + itemA)
elif not itemBPrice:
await client.say('No match found for ' + itemB)
Pass the invocation context into the command, then use that to get the name of the user who invoked the command. From there, you can use ctx.message.author.name, and insert that in your footer:
#client.command(aliases= ['price', 'p'], pass_context=True)
async def calc(ctx, quantity: int, itemA: str, itemB: str):
itemAPrice = items[aliases[itemA]]
itemBPrice = items[aliases[itemB]]
if itemAPrice and itemBPrice:
itemQuotient = itemAPrice/itemBPrice
itemBEquivalent = round(quantity * itemQuotient, 2)
embed=discord.Embed(title="Exchange Rate", description='{quantity} {itemA} is equal to {itemBEquivalent} {itemB}'.format(quantity = quantity, itemA = itemA, itemBEquivalent = itemBEquivalent, itemB = itemB), color=0xDA70D6)
embed.set_footer(text="Command invoked by {}".format(ctx.message.author.name))
await client.say(embed=embed)
elif not itemAPrice:
await client.say('No match found for ' + itemA)
elif not itemBPrice:
await client.say('No match found for ' + itemB)
If you want to mention the user, you can use ctx.message.author.mention instead
Looks like you can't, only text and icon are supported
