Python 如何阻止Pyrebase set（）覆盖现有数据？

我正在使用Flask&pyrbase；我已经成功地创建了登录ok和注册表。登录并注册后，用户将重定向到其个人资料页面

我的问题是，当我尝试添加一个新条目时，我的现有数据被覆盖。当我创建一个新的db条目时，我使用set（）而不是push（），我想这可能是为什么

我已经尽可能地缩短了代码

创建帐户和注册业务：

@app.route('/register', methods=['GET', 'POST'])
def register():
unsuccessful = 'Please check your credentials'
successful = 'Registraion successful'
    if request.method == 'POST':
        email = request.form.get('email')
        confirmEmail = request.form('confirmEmail')
        password = request.form.get('pass')
        userName = request.form.get('inputName')
        businessName = request.form.get('businessName')
        startYear = request.form.get('startYear')
        selectCategory = request.form.get('selectCategory')
        businessDescription = request.form.get('businessDescription')
        businessAddress = request.form.get('businessAddress')
        businessTown = request.form.get('businessTown')
        businessCity = request.form.get('businessCity')
        businessPostcode = request.form.get('businessPostcode')
        businessNumber = request.form.get('businessNumber')
        businessEmail = request.form.get('businessEmail')
        bameRegister = dict(
            userName = userName,
            confirmationEmail = confirmEmail,
            businessName = businessName,
            businessStartYear = startYear,
            businessCategory = selectCategory,
            businessDescription = businessDescription,
            businessAddress = [businessAddress, businessTown, businessCity, businessPostcode],
            businessNumber = businessNumber,
            businessEmail = businessEmail,
        )
        if selectCategory == "arts":
            try:
                user = auth.create_user_with_email_and_password(email, password)
                auth.send_email_verification(user['idToken'])
                db.child("Bame_Buisness").child("business").child("arts").set(bameRegister, user['idToken'])
                return render_template('homepage.html', x=successful)
            except:
                return render_template('homepage.html', y=unsuccessful)
        elif selectCategory == "food":
            try:
                user = auth.create_user_with_email_and_password(email, password)
                auth.send_email_verification(user['idToken'])
                db.child("Bame_Business").child("business").child("food").set(bameRegister, user['idToken'])
                return render_template('homepage.html', x=successful)
            except:
                return render_template('homepage.html', y=unsuccessful)
       elif selectCategory == "health":
           try:
               user = auth.create_user_with_email_and_password(email, password)
               auth.send_email_verification(user['idToken'])
               db.child("Bame_Business").child("business").child("health").set(bameRegister, user['idToken'])
               return render_template('homepage.html', x=successful)
            except:
               return render_template('homepage.html', y=unsuccessful)
    return render_template('homepage.html')

创建登录名：

@app.route('/login', methods=['GET', 'POST'])
def login():
    unsuccessful = 'Please check your credentials'
    if request.method == 'POST':
        try:
            user = auth.sign_in_with_email_and_password(email, password)
            signed_in_user = auth.get_account_info(user['idToken'])
            artCategory = db.child("Bame_Business").child("business").child("arts").get(user['idToken']).val()
            foodCategory = db.child("Bame_Business").child("business").child("food").get(user['idToken']).val()
            healthCategory = db.child("Bame_Business").child("business").child("health").get(user['idToken']).val()
            if signed_in_user['users'][0]['email'] == artCategory['confirmationEmail']:
                return render_template('profile.html', artCategory=artCategory)
            elif signed_in_user['users'][0]['email'] == foodCategory['confirmationEmail']:
                return render_template('profile.html', foodCategory=foodCategory)
            elif signed_in_user['users'][0]['email'] == healthCategory['confirmationEmail']:
                return render_template('profile.html', healthCategory=heathCategory)
        except:
            return render_template('homepage.html')
    return render_template('homepage.html')

这是登录后创建新业务的路径：

@app.route('newBusiness', methods=['GET', 'POST'])
def newBusiness():
    if request.method == 'POST':
        email = request.form.get('email')
        confirmEmail = request.form.get('confirmEmail')
        password = request.form.get('pass')
        userName = request.form.get('userName')
        businessName = request.form.get('businessName')
        startYear = request.form.get('startYear')
        selectCategory = request.form.get('selectCategory')
        businessDescription = request.form.get('businessDescription')
        businessAddress = request.form.get('businessAddress')
        businessTown = request.form.get('businessTown')
        businessCity = request.form.get('businessCity')
        businessPostcode = request.get('businessPostcode')
        businessNumber = request.form.get('businessNumber')
        businessEmail = request.form.get('businessEmail')
        bameRegister = dict(
            userName = userName,
            confirmationEmail = confirmEmail,
            businessName = businessName,
            businessStartYear = startYear,
            businessCategory = businessCategory,
            businessDescription = businessDescription,
            businessAddress = [businessAddress, businessTown, businessCity, businessPostcode],
            businessNumber = businessNumber,
            businessEmail = businessEmail,
        )
        if selectCategory == "arts":
            try:
                user = auth.sign_in_with_email_and_password(email, password)
                user = auth.refresh(user['refreshToken'])
                db.child("Bame_Business").child("business").child("arts").set(bameRegister, user['idToken'])
                signed_in_user = auth.get_account_info(user['idToken'])
                artCategory = db.child("Bame_Business").child("business").child("arts").get(user['idToken']).val()
                if signed_in_user['users'][0]['email'] == artCategory['confirmationEmail']:
                   return render_template('profile.html', artCategory=artCategory)
            except:
                return render_template('homepage.html')
        elif selectCategory == "food":
            try:
                user = auth.sign_in_with_email_and_password(email, password)
                user = auth.refresh(user['refreshToken'])
                db.child("Bame_Business").child("business").child("food").set(bameRegister, user['idToken'])
                signed_in_user = auth.get_account_info(user['idToken'])
                foodCategory = db.child("Bame_Business").child("business").child("food").get(user['idToken']).val()
                if signed_in_user['users'][0]['email'] == foodCategory['confirmationEmail']:
                    return render_template('profile.html', foodCategory=foodCategory)
            except:
                return render_template('homepage.html')
        elif selectCategory == "health":
            try:
                user = auth.sign_in_with_emal_and_password(email, password)
                user = auth.refresh(user['refreshToken'])
                db.child("Bame_Business").child("business").child("health").set(bameRegister, user['idToken'])
                signed_in_user = auth.get_account_info(user['idToken'])
                healthCategory = db.child("Bame_Business").child("business").child("health").get(user['idToken']).val()
                if signed_in_user['users'][0]['email'] == healthCategory['confirmationEmail']:
                    return render_template('profile.html', healthCategory=healthCategory)
            except:
                return render_template('homepage.html')
    return render_template('homepage.html')

用户登录后，假设他们在arts类别中注册了第一个业务，当他们在arts类别中注册了第二个不同的业务时，Firebase中的原始集合将被覆盖。即使在选择其他类别时也会发生这种情况。这绝对是不理想的，因为有人可能会覆盖其他人的数据，从而导致各种各样的问题

我知道您可以使用push&set在pyrbase中创建新条目；我之所以选择set，是因为当我使用push时，它创建了一个唯一的标记，我发现很难从用户帐户获得单独的访问权限。使用set方法，可以很容易地通过

artCategory['businessName']

或

artCategory['businessDescription']

或

artCategory['confirmationmail']

等调用我想要的词典部分

我只需要在登录后创建一个新的商业登记，而不覆盖任何现有数据，如果有人能帮我想出一个解决方案，将不胜感激

亲切问候

.set（）

覆盖

.update（）

仅更新已更改的字段。

因此，我必须使用

.push（）

？
