Setting up Alarm notification with Popup

[Abraham Francisco]

Been quite a journey for me thus far and I'm finally getting to the meat and potatoes of what my app is supposed to do.

Would like to first off thank this forum for all the help thus far,

Where I'm at now, I've made an alarm method that in theory I thought would check the current time, check if it coincides with the set alarm time, then play a specific sound. Unfortunately, nothing happens. lol Not sure where to go next. Any suggestions on why things aint working?

Here's my code. I used a random .mp3 file as the loaded sound but left it blank in my code here just so you can use your own file.

There are a few things to work here. 

The most important is where you are testing the for the alarm.

The code to check if an alarm time has been reached needs to go into your update_time method.  You are entering this method once per second to update the time, you also need to check if the alarm time has been reached here.

 

To access the alarm times from the update_time method you would do the following:

 

class MyClock(Label):

    current_time = StringProperty(strftime("%I:%M:%S %p"))

 

    def __init__(self, **kwargs):

        Clock.schedule_interval(self.update_time, 1)

        super().__init__(**kwargs)

 

    def update_time(self, dt):

        self.current_time = strftime("%I:%M:%S %p")

        app = App.get_running_app()

        t1 = app.root.ids.sm.get_screen(‘edit_1_page’).alarm(self.current_time) 

        # the alarm current code needs to change – you are passing in the current time, the alarm knows the alarm time.

        # make sure the format of the current_time and the alarm are the same for the comparison.

 

I also recommend you crete some content for your popup, at least a button that can dismiss the popup.

So here's my attempt. I think I'm stuck in how to properly format in strftime my alarm_time. Added a few lines trying to feel my way to the answer but I'm still getting no sound and now I get error:

     self.passed_alarm = formatted_alarm.strftime("%I %M %S")
 AttributeError: 'list' object has no attribute 'strftime'

Code Below:

        app = App.get_running_app()
        t1 = app.root.ids.sm.get_screen('edit1_page').alarm(self.current_time)

class AlarmEdit(Screen):  # Moved to the screen
    alarm_time = StringProperty()
    alarm_am_state = StringProperty('down')  # set default values
    alarm_pm_state = StringProperty('normal')

    # formatted_alarm = StringProperty()
    passed_alarm = StringProperty()

    def __init__(self, **kwargs):
        super().__init__(**kwargs)
        if os.path.isfile("alarm1_details.txt"):
            with open("alarm1_details.txt", "r") as f:
                d = f.read().split(",")
                self.alarm_time = d[0]
                self.alarm_am_state = d[1]
                self.alarm_pm_state = d[2]

    def set_alarm(self):
        # am_pm = {'down': 'AM', 'normal': 'PM'}[self.alarm_am_state]

        self.alarm_time = f"{self.ids.alarmtime.text}:00"
        formatted_alarm = self.alarm_time.split(":")
        self.passed_alarm = formatted_alarm.strftime("%I %M %S")
        # alarm_1 = self.alarm_time
        # self.alarm(alarm_1)

        with open("alarm1_details.txt", "w") as f:
            f.write(f"{self.ids.alarmtime.text},{self.alarm_am_state},{self.alarm_pm_state}")
        # print(f'Alarm time set: {self.alarm_time}')

    def alarm(self, current_time):
        if self.passed_alarm == current_time:
            popup = Popup(title='Alarm 1', content=Label(text=self.alarm_time), size_hint=(None, None), size=(400, 400))

            popup.open()
            sound = SoundLoader.load("")
            sound.play()


class MyButton(ToggleButtonBehavior, Label, Image):
    def __init__(self, **kwargs):
        super(MyButton, self).__init__(**kwargs)
        self.source = 'atlas://data/images/defaulttheme/checkbox_off'

    def on_state(self, widget, value):

[Elliot Garbus]

The code below works.  Here is a summary of the most significant changes.

def alarm(self, current_time):
        am_pm = {'down': 'AM', 'normal': 'PM'}[self.alarm_am_state]
        a_time = f'{self.alarm_time}:00 {am_pm}'
        if a_time[1] == ':':  # if the : is the second char,a leading zero is missing, insert it.
            a_time = '0' + a_time
        print(f'a: {a_time} ct: {current_time}')  # test to watch the time...
        if a_time == current_time:
            popup = Popup(title='Alarm 1', content=Label(text=self.alarm_time), size_hint=(None, None), size=(400, 400))
            popup.open()
            sound = SoundLoader.load('Ring05.wav')
            sound.play()

The method alarm() is called every second by the update_time() method.

It constructs a string a_time that matches the formatting of the current_time.  The time can be entered with or without a leading zero.  If a ‘:’ is the second character in the string, a ‘0’ is prepended, to ensure the formatting matches.

The alarm time and the current time are printed to support debug.  The Popup comes up and the sound plays.

The set_alarm() method was simplified.

 

You might want to consider creating a text input widget that only allows a valid time to be entered.

Full code with update below:

-----

# am_pm = {'down': 'AM', 'normal': 'PM'}[self.alarm_am_state]
        self.alarm_time = self.ids.alarmtime.text
        # formatted_alarm = self.alarm_time.split(":")
        #
        # self.passed_alarm = formatted_alarm.strftime("%I %M %S")

        # alarm_1 = self.alarm_time
        # self.alarm(alarm_1)

        

with open("alarm1_details.txt", "w") as f:
            f.write(f"{self.ids.alarmtime.text},{self.alarm_am_state},{self.alarm_pm_state}")
        # print(f'Alarm time set: {self.alarm_time}')

    def alarm(self, current_time):
        am_pm = {'down': 'AM', 'normal': 'PM'}[self.alarm_am_state]
        a_time = f'{self.alarm_time}:00 {am_pm}'
        if a_time[1] == ':':  # if the : is the second char,a leading zero is missing, insert it.
            a_time = '0' + a_time
        print(f'a: {a_time} ct: {current_time}')  # test to watch the time...
        if a_time == current_time:
            popup = Popup(title='Alarm 1', content=Label(text=self.alarm_time), size_hint=(None, None), size=(400, 400))
            popup.open()
            sound = SoundLoader.load('Ring05.wav')
            sound.play()

class MyButton(ToggleButtonBehavior, Label, Image):
    def __init__(self, **kwargs):
        super(MyButton, self).__init__(**kwargs)
        self.source = 'atlas://data/images/defaulttheme/checkbox_off'

    def on_state(self, widget, value):
        if value == 'down':
            self.source = 'atlas://data/images/defaulttheme/checkbox_on'
        else:
            self.source = 'atlas://data/images/defaulttheme/checkbox_off'

I'm sure your code works buts I'm looking at mine and if formatted_alarm did equal the right time code and I made sure to always put a 0 before a single digits numbers when setting my alarm, then shouldn't my version work as well?

[Abraham Francisco]

Is adding in if it's am or pm necessary when matching time formats? Could that be why my code didn't work. Hmm

[Elliot Garbus]

The current time is formatted as:

09:34:10 PM

So we need to match that. 

 

You were making changes to set alarm, creating an attribute that would hold the time in a format to compare current time:

        formatted_alarm = self.alarm_time.split(":")

This will create a list of items separated at the ‘:’ or using 09:34:10 PM’

[‘09’, ‘34’, ’10 PM]  I’m not sure what you were trying here, perhaps you were going to convert hours and minutes to ints for the compare operation.

        self.passed_alarm = formatted_alarm.strftime("%I %M %S")

The line above was the line that was failing – I’m not sure what you were trying to do here.
