Discord.py json文件而不是添加新值，json将所有值替换为一个

Question

所以，我创建了将用户输入存储到 json 文件中的命令，代码如下：

       for user in client.users:
            with open('suggestions.json', 'r') as f:
                h = json.load(f)

             h[str(f'{user.id} | {user.name} ')] = message.content

            with open('suggestions.json', 'w') as f:
                json.dump(h, f, indent=4)

问题在于，当两个或多个不同的用户使用该命令时，他们的所有输入都会在最后一个输入中发生变化，例如：

{
    "ID| USER NAME ": "ol",
    "ID | USER NAME ": "ol",
    "ID | USER NAME ": "ol"
}

由于某种原因，还存储了用户输入的机器人名称和 ID，以及在那一秒输入的所有成员或机器人，其值与发出命令的人相同，我尝试了很多东西，我真的不知道，也许只是使用数据库，但 atm 我对此一无所知。

为了更好地查看，我的命令此时看起来像这样：

@client.command()
async def suggestion(ctx):
    await ctx.send("You want to submit a suggestion?")
    message = await client.wait_for ('message' ,timeout=25, check = lambda m: m.author == ctx.author and m.channel == ctx.channel)

    if message.content == "yes"  :
        await ctx.send("Good choice, now let's hear your suggestion : ")

        message = await client.wait_for('message', timeout=25, check=lambda m: m.author == ctx.author and m.channel == ctx.channel)
        await ctx.send("Alirght, i will send this suggestion to the developer, thanks ! ")
        for user in client.users:
            with open('suggestions.json', 'r') as f:
                h = json.load(f)

            h[str(f'{user.id} | {user.name} ')] = message.content

            with open('suggestions.json', 'w') as f:
                json.dump(h, f, indent=4)

    elif message.content == "no":
        await ctx.send("Too bad, please use this command just if you have any ideas.")

所以，你正在做一个简单的建议命令，这是用于将数据完美地存储在 json 中的方式:)

def saveJson(data, file):
    json.dump(data, open(file, "w"), indent = 4)

_suggestions = open('./suggestions.json', 'r')
suggestions = json.load(f)
_suggestions.close()

@client.command()
async def suggest(ctx, *, message):
    user = ctx.author.id
    username = str(ctx.author)
    for current_user in suggestions['users']:
        if current_user['id'] == user:
            current_user['suggestions'].append(message)
            if username != current_user['name']:
                current_user['name'] = username
            break
    else:
        suggestions['users'].append({
            'id':user,
            'name':username,
            'suggestions': [message]
        })
    saveJson(suggestions, "./suggestions.json")

您的 json 文件应如下所示，

{
    'users': [
        {
            'id': 123456789,
            'name': 'billy#1234',
            'suggestions: [
                'be good',
                'drink milk',
                'eat cookies'
            ]
        },
        {
            'id': 1234512345,
            'name': 'willy#1234',
            'suggestions: [
                'don't be good',
                'don't drink milk',
                'don't eat cookies',
                'drink orange juice'
            ]
        }
}
