Python：无法从导入的模块调用方法

Question

I have a simple function to log a user in. It first comfirms whether the users details are correct;

import user    


@app.route("/login/", methods=['POST', 'GET'])
def login():
    if request.method == 'GET':
        return render_template('login.html')
    else:
        _email = request.form['email']
        _password = request.form['password']
        if user.loginValidate(_email, _password) == True:
            session['username'] = user.getUserName(_email)
            session['loggedin'] = True
            return redirect(url_for('home'))
        else:
            flash('Email or password incorrect!')
            return render_template('login.html')

Now for some reason when I try to call loginValidate I get an error that 'function' object has no attribute loginValidate .

The module does have loginValidate which returns either True or False , so I don't see what the issue is.

loginValidate (within user module):

def loginValidate(this_email, this_password):
    db = sqlite3.connect('data')
    cursor = db.cursor()
    cursor.execute("SELECT password FROM users WHERE email = ?", (this_email,))
    row = cursor.fetchone()
    hash = row[0]
    db.close()
    return hash == bcrypt.hashpw(this_password, hash)

Any help is appreciated!

Answer 1

Try:

from user import loginValidate

And:

if loginValidate(_email, _password) == True:

While I can't exactly point to where this arises, the error itself seems a clear enough hint. Python thinks that "user" is a function, not a module. Maybe there's a "user" function defined somewhere else, and python actually imports that
