Retrieve Data from Firebase Database to Kivy App

[Lizzie Faye]

Hi,
I've been having some trouble accessing the path of an id that is located in a .kv file

On my main.py, I have imported the necessary libraries and also have the configurations and inistialization of firebase. I have this command that gets the data from the databse. However, I'm having trouble when passing the data/value to the id. 

Here's my code on my main.py

def get_user_data1(self, account_username):

       

        user_id = account_username

        username = database.child(user_id).child("UsersData1").child("Username").get().val()

      

        self.root.get_screen("account").ids.account_username.text = username

My account.kv file has the id account_username

MDScreen:

    name:"account"

    MDFloatLayout:

        md_bg_color: 1, 1, 1, 1        

        MDIconButton:

            icon: "chevron-left-circle"

            pos_hint: {"center_x": .1, "center_y": .945}

            user_font_size: "10sp"

            theme_text_color: "Custom"

            text_color:  rgba(11, 69, 128, 255)

            on_release:

                root.manager.transition.direction = "right"

                root.manager.current = "home"

        MDTextButton:

            text: "Back"

            font_name: "MPoppins"

            theme_text_color: "Custom"

            font_size: "18sp"

            text_color: rgba(11, 69, 128, 255)

            pos_hint: {"center_x": .23, "center_y": .946}

            on_release:

                root.manager.transition.direction = "right"

                root.manager.current = "home"

    MDFloatLayout:

        size_hint: .9, .09

        pos_hint: {"center_x": .5, "center_y": .85}

        md_bg_color: rgba(241, 241, 243, 255)

        radius: [10]

        Image:

            source: 'assets/account_small.png'

            size_hint: .5, .5

            pos_hint: {"center_x": .11, "center_y": .5}

           

        MDLabel:

            text: "> Home > Account"

            font_name: "MPoppins"

            font_size: "15sp"

            pos_hint: {"center_x": .69, "center_y": 0.5}

            color: rgba(146,146,148,255)

<AccountInfo1>:

    MDIcon:

        icon: "card-account-details"

        font_size: "18sp"

        pos_hint: {'center_x': 0.13, 'center_y': 0.77}

        theme_text_color: "Custom"

        text_color: rgba(11, 69, 128, 255)

    MDLabel:

        text: "Username"

        font_name: "MPoppins"

        font_size: "18sp"

        pos_hint: {'center_x': 0.67, 'center_y': 0.77}

        color: rgba(112, 177, 220, 255)

    MDFloatLayout:

        size_hint: .85, .09

        pos_hint: {'center_x': 0.5, 'center_y': 0.7}

        canvas:

            Color:

                rgb: rgba(241, 241, 243, 255)

            RoundedRectangle:

                size: self.size

                pos: self.pos

                radius: [10]    

        MDLabel:

            id: account_username

            #text: root.account_username_label

            #text: "Ethel"

            font_name: "MPoppins"

            font_size: "14sp"

            size_hint: 1, None

            pos_hint: {'center_x': 0.55, 'center_y': 0.5}

            theme_text_color: "Custom"

            text_color: rgba(55, 112, 148, 255)

        

Also the get_user_data1 is called when the button is released in a separate .kv file, login.kv

I've tried fixing my path to the id but i can't get it right. Also, I always get this error
 
AttributeError: 'super' object has no attribute '__getattr__'. Did you mean: '__setattr__'?

Any help would be appreciated. Thanks!

Where are you instancing AccountInfo1 ?

 

The id you are trying to access is not in the “account” screen, it is in AccountInfo1, if you are instancing and adding AccountInfo1 with python you would need to use the children list of the account screen to get to AccountInfo1, then use the ids.

 

There are a number of techniques you could use to simplify accessing the widget – but there is not enough info here to suggest an approach.

Ooops, I didn't include the instance of AccountInfo1. Thanks for pointing that out! The issue is finally fixed.
