Find out if someone has a role
提问by R. Gillie
I made a simple quote bot for a server, but the admin only wants mod+ people to be able to add quotes to avoid spam. I went to the documentation and did everything, but I can't get this to work. Here's what I have:
我为服务器制作了一个简单的报价机器人，但管理员只希望 mod+ 人员能够添加报价以避免垃圾邮件。我去了文档并做了所有事情，但我无法让它工作。这是我所拥有的：
//other code
else if (command === "addquote" && arg) {
let adminRole = message.guild.roles.find("name", "Admin");
let modRole = message.guild.roles.find("name", "Mod");
if(message.member.roles.has(adminRole) || message.member.roles.has(modRole)){
const hasArr = arr.some((el) => {
return el.toLowerCase().replace(/\s/g, '') === arg.toLowerCase().replace(/\s/g, '');
});
if(hasArr){
message.channel.send(arg.replace(/\s+/g,' ').trim() + " is already a Quote");
} else {
fs.appendFileSync('./Quotes.txt', '\r\n' + arg);
message.channel.send("Quote added: " + arg);
arr.push(arg);
}
}
}
It's very finicky. Sometimes it will work if the user has the mod role, most of the times it wont. If I do
它非常挑剔。如果用户具有 mod 角色，有时它会起作用，大多数时候它不会。如果我做
console.log(message.memeber.roles.has(adminRole));
console.log(message.memeber.roles.has(modRole));
both will output to false, but will work? Honestly, I have no idea at this point.
两者都会输出为false，但会起作用吗？老实说，我现在不知道。

The discord.js api has been updated and there is a better way since .exists()has been deprecated.
discord.js api 已更新，并且有更好的方法，因为.exists()已被弃用。
if (message.member.roles.some(role => role.name === 'Whatever')) {}
if (message.member.roles.some(role => role.name === 'Whatever')) {}
This is better than .find()because .find()returns the role object (or undefined) which is then converted into a boolean. The .some()method returns a boolean by default.
这比.find()因为.find()返回角色对象（或未定义），然后将其转换为布尔值要好。该.some()方法默认返回一个布尔值。

message.member.rolesis a collection. Instead of getting the roles object, then looking for it, just look for the role directly in the collection. Try this:
message.member.roles是一个集合。而不是获取角色对象，然后寻找它，只需直接在集合中寻找角色。尝试这个：
else if (command === "addquote" && arg) {
if(message.member.roles.find(r => r.name === "Admin") || message.member.roles.find(r => rname === "Mod")){
//Rest of your code
}
Note, the role name must be the name you put in the find including any emojis if there's any in the role name.
请注意，角色名称必须是您在查找中输入的名称，如果角色名称中有任何表情符号，则包括任何表情符号。

This worked for me with version 12.2.0
这对我的 12.2.0 版有用
if(message.member.roles.cache.find(r => r.name === "Admin")) {
// Your code
}
You can also use r.idto check with the role id
您还可以使用r.id来检查角色 ID
