ボタンを押してデータの書き換えをしたい

https://teratail.com/questions/73935
これの続きです。

評価されてない画像データを１つだけ表示して、ボタンで画像の種類を分類したいです。

python
1class Image(db.Model):
2    __tablename__ = 'images'
3    id = db.Column(db.Integer, primary_key=True)
4    name = db.Column(db.String(100), default='', nullable=False)
5    good = db.Column(db.Integer)
6    normal = db.Column(db.Integer)
7    bad = db.Column(db.Integer)

html
1{% extends "layout.html" %}
2<div class=image>
3{% block body %}
4
5    {% if session.user_id %}
6    {{ message }}
7    <img src={{ image.name }}>
8
9    #どうやって、何の要素を渡せばいいのだ・・・
10    <form action="{{ url_for('classify_images', image_id=image.id) }}" method=post class=classify-images>
11        <button type=submit class=good>GOOD</button>
12        <button type=submit class=normal>NORMAL</button>
13        <button type=submit class=bad>BAD</button>
14    </form>
15    {% endif %}
16
17{% endblock %}
18</div>

python
1@app.route('/image/', methods=['GET'])
2@login_required
3def show_image():
4    images = Image.query.all()
5    for image in images:
6        #評価されてない画像を出す、これでいいのか？
7        if image.good is None:
8            return render_template('classify_images.html', image=image)
9        else:
10            flash('All images are classified')
11    return render_template('classify_images.html', message="mou de-ta naidesu")
12
13
14@app.route('/classify', methods=['GET','POST'])
15@login_required
16def classify_images(image_id):
17    image = Image.query.get(image_id)
18    '''
19    ここら辺がグダッてる、よくわからん。GOODのボタンが押されたらgoodに１を他のには0を、
20    NORMALのボタンが押されたらnormalに1を他のには０をみたいな感じでやりたい
21    こういう感じでやりたいです・・・
22    '''
23    if request.form == ['good']:
24        image.good = 1
25        image.normal = 0
26        image.bad = 0
27    db.session.add(image)
28    db.session.commit()
29    flash('New classification was successfully posted')
30    return redirect(url_for('show_image'))

よろしくお願いします・・・・

html
1 <form action="{{ url_for('classify_images', image_id=image.id) }}" method=post class=classify-images>
2        <button type=submit value=good>GOOD</button>
3        <button type=submit value=normal>NORMAL</button>
4        <button type=submit value=bad>BAD</button>
5    </form>

python
1@app.route('/classify', methods=['GET', 'POST'])
2def classify_images(image_id):
3    image = Image.query.get(image_id)
4    if request.form['good']:
5        image.good = 1
6        image.normal = 0
7        image.bad = 0
8    if request.form['normal']:
9        image.good = 0
10        image.normal = 1
11        image.bad = 0
12    if request.form['bad']:
13        image.good = 0
14        image.normal = 0
15        image.bad = 1
16    db.session.add(image)
17    db.session.commit()
18    flash('New classification was successfully posted')
19    return redirect(url_for('show_image'))

こんな感じか・・・？

python
1@app.route('/classify', methods=['GET','POST'])
2@login_required
3def classify_images(image_id):
4    image = Image.query.get(image_id)
5    image.good = 0
6    image.normal = 0
7    image.bad = 0
8    if request.form['good']:
9        image.good = 1
10    if request.form['normal']:
11        image.normal = 1
12    if request.form['bad']:
13        image.bad = 1
14    db.session.add(image)
15    db.session.commit()
16    flash('New classification was successfully posted')
17    return redirect(url_for('show_image'))

こうかな・・・？

↑をこうした

python
1@app.route('/image/<int:image_id>/classify', methods=['GET','POST'])
2@login_required
3def classify_images(image_id):
4    image = Image.query.get(image_id)
5    image.good = 0
6    image.normal = 0
7    image.bad = 0
8    if request.form['good']:
9        image.good = 1
10    if request.form['normal']:
11        image.normal = 1
12    if request.form['bad']:
13        image.bad = 1
14    db.session.add(image)
15    db.session.commit()
16    flash('New classification was successfully posted')
17    return redirect(url_for('show_image'))

そしたら、

BAD Request
The browser (or proxy) sent a request that this server could not understand.

こうなった

この時点でhtmlのmethodがmethoになってたっぽい・・・
細かい所気をつけよう
