Question

当我尝试使用Flask-WTForms时，我按照以下步骤操作：

from flask_wtf import Form
from wtforms import StringField, PasswordField
from wtforms.validators import DataRequired, Email

class EmailPasswordForm(Form):
    email = StringField('Email', validators=[DataRequired(), Email()])
    password = PasswordField('Password', validators=[DataRequired()])

@app.route('/form',methods=['GET','POST'])
def email_form():
    form = EmailPasswordForm()
    return render_template('form.html',
       title = 'Sign In',
       form = form)

然后我得到TypeError：类型'_RequestGlobals'的参数不可迭代。

这是form.html：

<html>
<head>
    <title>Login Page</title>
</head>
<body>
    <form action="{{ url_for("form") }}" method="POST">
        <input type="text" name="email" />
        <input type="password" name="password" />
        {{ form.csrf_token }}
    </form>
</body>

Answer 1

这是由于您的视图功能的名称。只需更改名称即可。它应该工作正常。

@app.route('/test',methods=['GET','POST'])
def my_form(): # See this line
    form = EmailPasswordForm()
    return render_template('form.html',
       title = 'Sign In',
       form = form)

'_RequestGlobals'类型的Flask参数不可迭代
