I want to make per server channels

What i mean with 'per server' is that the channel is bound to a server Here is the code i made:

def get_channel(client,message):
    with open('channels.json', 'r') as f:
        channels = json.load(f)
    return channels[str(message.guild.id)]

@client.event
async def on_guild_join(guild):
    with open('channels.json', 'r') as f:
        channels = json.load(f)
    channels[str(guild.id)] = ''
    with open('channels.json', 'w') as f:
        json.dump(channels,f)

@client.command()
async def cc(ctx, prefix):
    guild = ctx.guild
    with open('channels.json', 'r') as f:
        channels = json.load(f)
    channels[str(guild.id)] = prefix
    with open('channels.json', 'w') as f:
        json.dump(channels,f)
    await ctx.send('done')

This is the code where i put the function in

@client.event
async def on_member_join(member):
    channel = discord.utils.get(member.guild.channels, name=get_channel)
    await channel.send(f'Welcome {member.mention}')

The text in the database is correct The error i got: await channel.send(f'Welcome {member.mention}') AttributeError: 'NoneType' object has no attribute 'send'

def get_channel(guild):
    with open('channels.json', 'r') as f:
        channels = json.load(f)
    return channels[str(guild.id)]

@client.event
async def on_guild_join(guild):
    with open('channels.json', 'r') as f:
        channels = json.load(f)
    channels[str(guild.id)] = ''
    with open('channels.json', 'w') as f:
        json.dump(channels,f)

@client.command()
async def channel_define(ctx, channel_name):
    guild = ctx.guild
    with open('channels.json', 'r') as f:
        channels = json.load(f)
    channels[str(guild.id)] = channel_name
    with open('channels.json', 'w') as f:
        json.dump(channels,f)
    await ctx.send('done')

@client.event
async def on_member_join(member):
    channel = discord.utils.get(member.guild.channels, name=get_channel(member.guild))
    await channel.send(f'Welcome {member.mention}')

This is the corrected version of the code. But I would advise you to register channel ids rather than names though.

If you want to use the get method with ids, refer to the doc : https://discordpy.readthedocs.io/en/stable/api.html#discord.utils.get

channel = discord.utils.get(member.guild.channels, name='get_channel')

In this line you search for a channel, among the channels of the guild the member has joined, which has the name 'get_channel'. But the get function doesn't find any, so it returns None. This channel does not exist, or the cache is not loaded for this guild.

To load the cache of a guild :

await guild.chunk()
