I am trying to create some buttons with Discord.Py where the labels change. I’ve created a discord.ui.View and then inside that I have an __init__ which accepts a name and id value. When I call the class, and add a break point on that I can see that the values are assigned to self.modelName and self.modelId, however, the button generated completely ignores these values, and uses the default values.

My class is defined as the following:

class AlphaStrikeCardButtons(discord.ui.View):
    modelName = "supernova 2"
    modelId = "3133"

    #defining constructor  
    def __init__(self,name,id):  
        super().__init__()
        self.modelName = name
        self.modelId = f'asc{id}'
        
    @discord.ui.button(label=modelName, custom_id=modelId, style=discord.ButtonStyle.blurple)
    #@discord.ui.button(label='supernova 5', custom_id='asc8132', style=discord.ButtonStyle.blurple)
    async def alphaStrikeCard(self, interaction: discord.Interaction, button: discord.ui.Button):
        cardPath = f'./tmp/asc{modelId}.png' #If it already exists, we don't need to download it again
        if os.path.isfile(cardPath) == False:
            cardUrl = f'http://masterunitlist.info/Unit/Card/{self.modelId}'
            print(cardUrl)
            urlretrieve(cardUrl,cardPath)
        cardFile = discord.File(cardPath,filename=f'{self.modelId}.png')
        await interaction.response.send_message(file=cardFile, ephemeral=False)
        self.stop()

Then then I call the class using:

ASCB = AlphaStrikeCardButtons(name=modelName,id=modelId)
await interaction.response.send_message("Please click the button:",ephemeral=True,view=ASCB)

The values of modelName and modelId in are 'Supernova 5' and '8132', however, the button prompted displayed “Supernova 2” and has a custom_id of asc3133, which is the default values. I confirmed the values are assigned by adding a breakpoint and hovering over the variable:

You can clearly see that self.modelName has the value Supernova 5; so it was correctly assigned.

If I don’t assign values (assign None) to modelName and modelId at the start then when I call the class I get an even more confusing error:

In data.components.0.components.0.label: This field is required

So it’s saying I’m not even passing the value, but I most certainly am.

Why is Python ignoring the values set to the variables modelName and modelId when I’ve confirmed that the values are being assigned?
