我有保存表单(wtf)到(sqlalchemy)db的问题,表单正在渲染,但提交后没有任何反应...
例如:
127.0.0.1 - - [30/Dec/2013 10:30:24] "POST /add/ HTTP/1.1" 200 -
我试图在没有验证器的情况下保存
例如:
name = TextField('Task Name')
我试图以其他方式保存表格:
if request.method == 'POST' and form.validate():
new_task = Tasks(
form.name.data,
form.due_date.data,
form.priority.data,
form.posted_date.data,
session['user_id'],
form.category.data,
form.super_category.data,
form.description.data
)
db.session.add(new_task)
db.session.commit()
以下代码:
楷模 :
# -*- coding: utf-8; -*-
from app import db
import datetime
class Tasks(db.Model):
__tablename__ = "tasks"
task_id = db.Column(db.Integer,primary_key=True)
name = db.Column(db.String(255),nullable=False)
description = db.Column(db.Text,nullable=False)
priority = db.Column(db.Integer,nullable=False)
posted_date = db.Column(db.DATE,nullable=False)
status = db.Column(db.Integer,default=1,nullable=False)
category = db.Column(db.String(255),nullable=False)
super_category …我看不到我要去哪里错了。我安装了最新的WTF表单，但是仍然出现此错误。
方法：
from flask.ext.wtf import Form
from wtforms import PasswordField, validators, fields
from wtforms.fields import TextField, BooleanField
from wtforms.validators import Required, Email, EqualTo
结果：

return str(e) …我有一个表单,并在提交时我不断收到以下错误.我无法弄清楚问题是什么,但我认为这与selectfield有关,因为这是我第一次使用它而且之前没有遇到任何问题.
这是我的表格:
class CampaignForm(Form):
name = StringField('Campaign Name', validators=[DataRequired])
start = DateField('Start', validators=[DataRequired], format='%d-%m-%Y')
end = DateField('End', validators=[DataRequired], format='%d-%m-%Y')
budget = IntegerField('Budget', validators=[DataRequired])
customer_id = SelectField(
'Customer', validators=[DataRequired], coerce=int)
这是我的观点,GET有效,但我在POST时遇到错误:
@app.route('/campaign/add', methods=['GET', 'POST'])
@login_required
def campaign_add():
form = CampaignForm()
form.customer_id.choices = [
(customer.id, customer.name)
for customer in current_user.account.customers]
if form.validate_on_submit():
campaign = Campaign(name=form.name.data,
start=form.start.data,
end=form.end.data,
budget=form.budget.data,
account_id=current_user.account_id,
customer_id=form.customer_id.data,
created_at=datetime.now(),
created_by=current_user.id,
updated_at=datetime.now(),
updated_by=current_user.id)
db.session.add(campaign)
db.session.commit()
return redirect(url_for('campaigns'))
return render_template('campaigns/add.html', form=form)
这是我得到的错误,我无法弄清楚出了什么问题.

这段代码有什么问题？
class DriverTemplateSchedueForm(Form):
def __init__(self, per_day=30, **kwargs):
self.per_day = per_day
ages = model.Agency.query.all()
ages = [(a.id, a.name) for a in ages]
self.days = [[[]] * per_day] * 7

想象一下,我需要建立一个这样的旅行计划表:
Going from [_Picadily_Circus____]
Going to [_Marylebone_____]
(Starting by) (Arriving by) [5]:[30][pm]
两者(开始)(到达)是提交按钮.这个例子是人为的,以显示一个双按钮用例,所以我们不讨论可用性.
我如何使用Flask和WTForms做到这一点？
如何查看实际按下了哪个按钮？
我有一个Flask-WTF表单,需要从字典中填充,我将其传入**kwargs.该表单用于使用该POST方法访问的Flask路径.表单未验证,字段的值为None.如何将数据字典传递给我的表单然后验证它？
@app.route('/submit', methods=['POST'])
def submit():
data = {'name': 'eee'}
form = MyForm(**data)
print(form.validate()) # False, name is required
print(form.name.data) # None
我打了电话form.validate_on_submit(),但它又回来了False.如何找出表单未验证的原因？
