注意：
我知道我有很多问题，但我真的尝试了，但有任何成果。
我正在尝试让用户在我的端点中获得所选的选项，但是它不起作用。
我已经尝试过：
在选择html标记上写入属性名称。
在后端，我尝试了这两个选项
type_user = request.form.get('type_user')和这个
type_user = request.form['type_user']
我使用调试器模式，看到auth.py仅None并没有收到任何数据。
register.html
#I don't know if it is for the desabled attribute, if the user
#is not logged so he cannot create a admin account only a normal account.
{% if g.user['type'] == 0 %}
<div class="form-group">
<label for="type_user">Type of User <span style="color: red">*</span></label>
<select class="form-control" id="type_user" name="type_user" required>
<option value="0">Admin</option>
<option value="1">User</option>
</select>
</div>
{% else %}
<div class="form-group">
<label for="type_user">Type of User <span style="color: red">*</span></label>
<select class="form-control" id="type_user" name="type_user" required disabled>
<option value="1">User</option>
</select>
</div>
{% endif %}
auth.py
@bp.route('/register', methods=('GET', 'POST'))
def register():
if request.method == 'POST':
first_name = request.form['first_name']
last_name = request.form['last_name']
type_user = int(request.form.get('type_user'))
username = request.form['username']
password = request.form['password']
db = get_db()
error = None
print(type_user)
print(first_name)
if not (first_name and last_name and type_user and username and password):
error = "Please fill all requiered fields"
elif db.execute(
'SELECT id FROM user WHERE username = ?', (username,)
).fetchone() is not None:
error = 'User {} is already registered.'.format(username)
if error is None:
db.execute(
'INSERT INTO user (first_name, last_name, type, username, password) VALUES (?, ?, ?, ?, ?)',
(first_name, last_name, type_user, username, generate_password_hash(password))
)
db.commit()
return redirect(url_for('auth.login'))
flash(error)
return render_template('auth/register.html')
错误：
第15行中的文件“ D：\ Dev \ patterns-project \ study_room \ auth.py” 寄存器 -----> type_user = request.form ['type_user'] <-----文件“ d：\ dev \ patterns-project \ my-venv \ lib \ site- packages \ werkzeug \ datastructures.py”，第442行，位于 getitem 引发异常。BadRequestKeyError（key）

我正在简化我的答案，以便更加清楚。
register.html -无需更改。你所拥有的有效。
auth.py -需要进行细微更改。下面的if / else语句添加到您的代码中：
@bp.route('/register', methods=('GET', 'POST'))
def register():
if request.method == 'POST':
first_name = request.form['first_name']
last_name = request.form['last_name']
### Start of changed section ###
# The line below will be None if type_user is disabled
# type_user = int(request.form.get('type_user'))
if "type_user" in request.form:
# Current user must be an admin and have the option to select
# the type_user for the new user, so read it here.
type_user = request.form["type_user"]
else:
# The type_user field in the form must be disabled.
# This means a standard user or anonymouse person
# must be registering a new user. So the new user
# must be a standard user.
type_user = 1
### End of changed section ###
username = request.form['username']
password = request.form['password']
db = get_db()
error = None
print(type_user)
print(first_name)
if not (first_name and last_name and type_user and username and password):
error = "Please fill all requiered fields"
elif db.execute(
'SELECT id FROM user WHERE username = ?', (username,)
).fetchone() is not None:
error = 'User {} is already registered.'.format(username)
if error is None:
db.execute(
'INSERT INTO user (first_name, last_name, type, username, password) VALUES (?, ?, ?, ?, ?)',
(first_name, last_name, type_user, username, generate_password_hash(password))
)
db.commit()
return redirect(url_for('auth.login'))
flash(error)
return render_template('auth/register.html')
在HTML中使用disabled的问题在于，它使<select>完全不可用。检查字典中的type_user可以处理这种情况，如下所示：
if "type_user" in request.form:
type_user = request.form["type_user"])
else:
type_user = 1
感谢@roganjosh指出我最初针对<div>的错误。
