60. 답글
ChatGPT에게 물었습니다.
I want to reply to the comment.
댓글에 대한 답글을 달고 싶어.
To add a reply feature to comments in your blog application using Vue, Vuex, Vuetify, and Firestore, follow these steps:
Vue, Vuex, Vuetify 및 Firestore를 사용하여 블로그 애플리케이션의 댓글에 답글 기능을 추가하려면 다음 단계를 따르세요.
- Modify the Comment Data Structure: Add a field for replies within each comment.
댓글 데이터 구조 수정: 각 댓글 내에 답변을 위한 필드를 추가합니다. - Update Firestore Schema: Adjust how comments are stored in Firestore to include replies.
Firestore 스키마 업데이트: 답변을 포함하도록 Firestore에 댓글이 저장되는 방식을 조정합니다. - Create a Reply Form: Allow users to add replies to existing comments.
답장 양식 만들기: 사용자가 기존 댓글에 답글을 추가할 수 있도록 허용합니다. - Display Replies: Show replies under each comment.
답글 표시: 각 댓글 아래에 답변을 표시합니다.
Updated Firestore Structure 업데이트된 Firestore 구조
Each comment will have a replies field, which will be an array of reply objects.
각 댓글에는 '답글' 필드가 있으며, 이는 응답 개체의 배열이 됩니다.
Step-by-Step Implementation 단계별 구현
Step 1: Modify Firestore Structure Firestore 구조 수정
When adding comments, include a replies array to store replies.
댓글을 추가할 때 답글을 저장할 replies 배열을 포함하세요.
Step 2: Update the PostDetailView.vue PostDetailView.vue 업데이트
Add a form to allow users to reply to comments and display those replies.
사용자가 댓글에 답글을 달고 해당 답글을 표시할 수 있도록 양식을 추가하세요.

Explanation 설명
1. Template:
- Added a button to show the reply form (<v-btn small @click="showReplyForm(comment.id)">Reply</v-btn>). 답변 양식을 표시하는 버튼을 추가했습니다.
(<v-btn small @click="showReplyForm(comment.id)">답글</v-btn>). - Added a reply form that appears when a user clicks the reply button (<v-form v-if="replyingTo === comment.id" @submit.prevent="addReply(comment.id)">). 사용자가 답글 버튼을 클릭하면 나타나는 답글 양식을 추가했습니다.
(<v-form v-if="replyingTo === comment.id" @submit.prevent="addReply(comment.id)">) - Displayed replies within each comment.
(<v-list v-if="comment.replies && comment.replies.length">).
각 댓글 내에 답변이 표시됩니다.
(<v-list v-if="comment.replies && comment.replies.length">).
2. Data:
- newReply: Model for the reply input field.
newReply: 답글 입력 필드의 모델입니다. - replyingTo: ID of the comment currently being replied to.
replyingTo: 현재 답글을 달고 있는 댓글의 ID입니다.
3. Methods:
- showReplyForm(commentId): Sets the replyingTo data property to the ID of the comment being replied to.
showReplyForm(commentId): replyingTo 데이터 속성을 답글을 달고 있는 댓글의 ID로 설정합니다. - addReply(commentId): Adds a reply to the specific comment in Firestore and updates the local comments array.
addReply(commentId): Firestore의 특정 댓글에 답글을 추가하고 로컬 댓글 배열을 업데이트합니다. - addComment: Adds a new comment to Firestore and includes an empty replies array in the comment object.
addComment: Firestore에 새 댓글을 추가하고 댓글 객체에 빈 replies 배열을 포함합니다.
By following these steps, you can implement a reply feature for comments, allowing logged-in users to reply to existing comments and view those replies.
다음 단계를 수행하면 로그인한 사용자가 기존 댓글에 답글을 달고 해당 답글을 볼 수 있도록 댓글에 대한 답장 기능을 구현할 수 있습니다.
ChatGPT에게 물었습니다.
Only logged in members can reply to comments.
댓글에 대한 답글도 로그인한 회원만 가능하도록 해줘.
To ensure that only logged-in users can reply to comments, you can modify the addReply method to check for user authentication and update the template to conditionally show the reply form based on the user's authentication status. Here's how you can do it:
로그인한 사용자만 댓글에 답글을 달 수 있도록 하려면 addReply 메소드를 수정하여 사용자 인증을 확인하고 사용자의 인증 상태에 따라 조건부로 답글 양식을 표시하도록 템플릿을 업데이트할 수 있습니다. 방법은 다음과 같습니다.
Step-by-Step Implementation 단계별 구현
Step 1: Update the Template 템플릿 업데이트
Modify the template to conditionally display the reply form only if the user is authenticated.
사용자가 인증된 경우에만 응답 양식을 조건부로 표시하도록 템플릿을 수정합니다.

Step 2: Update the Script 스크립트 업데이트
Modify the addReply method to check if the user is authenticated before allowing them to add a reply.
응답 추가를 허용하기 전에 사용자가 인증되었는지 확인하려면 addReply 메소드를 수정하세요.

Explanation 설명
1. Template Changes:
- Conditionally display the reply button (v-list-item-action v-if="isAuthenticated") based on whether the user is authenticated.
사용자 인증 여부에 따라 조건부로 응답 버튼(v-list-item-action v-if="isAuthenticated")을 표시합니다. - Conditionally display the reply form (v-form v-if="replyingTo === comment.id && isAuthenticated") based on whether the user is authenticated and if they are replying to a comment.
사용자의 인증 여부와 댓글에 대한 응답 여부에 따라 응답 양식(v-form v-if="replyingTo === comment.id && isAuthenticated")을 조건부로 표시합니다.
2. Script Changes:
- addReply method checks if the user is authenticated before adding a reply. If not authenticated, it sets an error message.
addReply 메소드는 답글을 추가하기 전에 사용자가 인증되었는지 확인합니다. 인증되지 않은 경우 오류 메시지를 설정합니다. - isAuthenticated computed property checks if there is a currently authenticated user.
'isAuthenticated' 계산 속성은 현재 인증된 사용자가 있는지 확인합니다.
By implementing these changes, only logged-in users will be able to see the reply button and reply to comments, ensuring that replies are only made by authenticated members.
이러한 변경 사항을 구현하면 로그인한 사용자만 답글 버튼을 볼 수 있고 댓글에 답글을 달 수 있으므로 인증된 회원만 답글을 작성할 수 있습니다.
