Members don't seem to have a banner attribute?

[glass-ships]

version: discord.py==2.0.0a4074+g95deb553

It could just be my implementation so I thought I'd ask here first before creating an issue or something.
I made a simple banner command that returns an embed with a user's banner:

@commands.command(name="banner", aliases=['b'])
async def banner(self, ctx, *, user: discord.Member=None):
    """
    Returns a user's Discord banner
    if a user is mentioned, or self if not.
    """
    if not user:
        u = ctx.author
    else:
        u = user
    userBannerUrl = u.banner.url
    embed = discord.Embed(description=f"{u.mention}'s banner")
    embed.set_image(url=f"{userBannerUrl}")
    await ctx.send(embed=embed)
    await asyncio.sleep(3.0)
    await ctx.message.delete()

The avatar equivalent works perfectly, but when calling [p]banner I keep getting the error:
Command raised an exception: AttributeError: 'NoneType' object has no attribute 'url'

Has anyone else run into this / found a workaround?

You need to fetch it, cause discord limitation.

[glass-ships]

Ahh, fetch the member or the banner asset?

[JDJGInc]

You need to use fetch_member to get the banner asset, it's not given by default.

Aha I see! Thanks so much, I'll update my code :)

[glass-ships]

Thanks again @JDJGInc that did the trick!

I should add for clarification purposes that, as the docs state - it's Client.fetch_user() or self.bot.fetch_user() in the case of a cog command.

Works like a charm!

The updated banner command, in case anyone will find the code useful:

    @commands.command(name="banner", aliases=['b'])
    async def banner(self, ctx, *, user: discord.Member=None):
        """
        Returns a user's Discord banner
        if a user is mentioned, or self if not.
        """
        if not user:
            u = ctx.author
        else:
            u = user
        mem = await self.bot.fetch_user(u.id)
        userBannerUrl = mem.banner

        embed = discord.Embed(description=f"{mem.mention}'s banner")
        embed.set_image(url=f"{userBannerUrl}")
        await ctx.send(embed=embed)
        await asyncio.sleep(3.0)
        await ctx.message.delete()

Fyi you could just use user = user or ctx.author
