主PY文件寫視圖函數，帶id參數。
@app.route('/detail/<question_id>')
def detail(question_id):
quest =
return render_template('detail.html', ques = quest)
首頁標題的標籤作帶參數的連接。
{{ url_for('detail',question_id = foo.id) }}
在詳情頁將數據的顯示在恰當的位置。
{{ ques.title}}
{{ ques.id }}{{ ques.creat_time }}

{{ ques.author.username }}
{{ ques.detail }}
創建評論的對象關係映射：css

class Comment(db.Model):
__tablename__='comment'html

嘗試實現發佈評論。app

@app.route('/detail/<question_id>')
def detail(question_id):
       quest=Question.query.filter(Question.id==question_id).first()
       return render_template('detail.html',ques=quest)
