점프 투 플라스크 207~8 페이지, 답변 댓글 설정시 detail페이지에 접근이 안되는 현상
점프 투 플라스크 207~8 페이지 진행중입니다.
<!-- 답변 댓글 Start -->
{% if answer.comment_set|length > 0 %}
<div class="mt-3">
{% for comment in answer.comment_set %}
<div class="comment py-2 text-muted">
<span style="white-space: pre-line;">{{ comment.content }}</span>
<span>
- {{ comment.user.username }}, {{ comment.create_date|datetime }}
{% if comment.modify_date %}
(수정일시:{{ comment.modify_date|datetime }})
{% endif %}
</span>
{% if g.user == comment.user %}
<a href="{{ url_for('comment.modify_answer', comment_id=comment.id) }}" class="small">수정</a>,
<a href="#" class="small delete"
data-uri="{{ url_for('comment.delete_answer', comment_id=comment.id) }}">삭제</a>
{% endif %}
</div>
{% endfor %}
</div>
{% endif %}
<div>
<a href="{{ url_for('comment.create_answer', answer_id=answer.id) }}" class="small">
<small>댓글 추가...</small>
</a>
</div>
<!-- 답변 댓글 End -->
위와 같이 코드 작성하고 detail 페이지 접근시 아래와 같은 메세지를 받습니다:
werkzeug.routing.BuildError: Could not build url for endpoint 'comment.create_answer' with values ['answer_id']. Did you forget to specify values ['comment_id']?
그리고 혹시 모를 단서를 추가하자면,
<a href="{{ url_for('comment.create_answer', answer_id=answer.id) }}" class="small">
<small>댓글 추가...</small>
</a>
위 코드의 answer_id를 comment_id로 바꾸면 detail페이지까지는 진행이 되는데, 답변의 '댓글 추가...'를 클릭하면 아래와 같은 메시지를 받습니다:
TypeError: create_answer() got an unexpected keyword argument 'comment_id'
어디를 손봐야 될지 모르겠습니다ㅠ 도와주세요

2개의 답변이 있습니다. 1 / 1 Page
comment_views.py의 create_answer 함수의 매개변수가 잘못된게 아닐까요?
작성하신 comment_views.py 파일을 봐야 알수 있을거 같습니다.
