How inline keyboard starts conversation handler, when ended edit existing message with inline keyboard - python-telegram-bot

Question

This is the code, a message is displayed with 3 vaiables that will be filled with the buttons, except for Hostname, that button will call a Conversation Handler in order to specify the hostname.
def custom_search_ask(update: Update, _: CallbackContext) -> None:
query = update.callback_query
query.answer()
query.edit_message_text(
text=f"Please configure the custom search:\nTime: {ctimechoosen}\nHostname: {chostnamechoosen}\nSeverity: {cseveritychoosen}",
reply_markup=custom_search_keyboard())
This is the keyboard with the options
def custom_search_keyboard():
keyboard = [[InlineKeyboardButton('Time', callback_data='time_menu')],
[InlineKeyboardButton('Hostname', callback_data='hostname_search')],
[InlineKeyboardButton('Severity', callback_data='severity_menu')],
[InlineKeyboardButton('Return back', callback_data='main')]]
return InlineKeyboardMarkup(keyboard)
The button that calls the conversation handler
def hostname_ask(update: Update, _: CallbackContext) -> None:
query = update.callback_query
#query.answer()
query.edit_message_text(text=f"Selected option: {query.data} \nPlease specify hostname:")
return HOSTNAME
Conversation handler:
entry_points= [
CallbackQueryHandler(hostname_ask, pattern='^hostname_search$')
]
states = {
HOSTNAME: [
MessageHandler(filters = Filters.all , callback = custom_search_hostname_choosen)
],
Edit message and anwser with the introduced user data with new inline keyboard
def custom_search_hostname_choosen(update: Update, _: CallbackContext) -> None:
message = update.effective_message
message.edit_text(
text=f"Hostname specified \nTime: {ctimechoosen}\nHostname: {chostnamechoosen}\nSeverity: {cseveritychoosen}\nConfigure other presets or search?",
reply_markup=search_yes_no())
Really thanks for the help.

Answer 1

In custom_search_hostname_choosen, the variable query will be an object of type Message - because update is of type Update and the attribute update.effective_message is a Message.
the class Message does not have a method edit_message_text. It does however have a method Message.edit_text. So you should change query.edit_message_text to query.edit_text. I also recommend to rename query to e.g. message to give it a more meaningful name.
