我想在Flask-Admin模型列表视图中仅显示付费订单.

这是models.py:

class Order(db.Model):
   id = db.Column(db.Integer, primary_key=True)
   amount = db.Column(db.Integer)
   description = db.Column(db.String)
   paid = db.Column(db.Boolean, default=False)

这是Flask-Admin的ModelView:

class OrderView(ModelView):
    column_filters = ("paid")


admin.add_view(OrderView(Order, db.session))

过滤器工作正常,但我想使此过滤器默认.或者更好的是,不要使用过滤器,只显示输出Order.query.filter(Order.paid==True)查询的订单.

是否可以使用Flask-Admin？

我正在尝试使用Flask-Admin的'master.html'模板扩展我的模板,如下所示:

{% extends 'admin/master.html' %}
{% block body %}
    Hello!!!
{% endblock %}

我得到错误:

以下是我正在初始化Flask-Admin的方法: …

我正在使用Flask和pyMongo开发一个web应用程序,我最近开始集成Flask-Admin模块(1.0.4),给出了新的mongodb支持.

使用ModelViews时,一切都很顺畅,但是当涉及到BaseView的子类化时,我根本无法使它工作.

这是我的设置:

user_view = Admin(app, name='User stuff', url="/user", endpoint="user")


class ProfileForm(wtf.Form):
    username = wtf.TextField('Username', [wtf.Required()])
    name = wtf.TextField('Name', [wtf.Required()])


class Profile(BaseView):
    @expose('/', methods=('GET', 'POST'))
    def profile(self):
        user = User(uid) # gets the user's data from DB
        form = ProfileForm(request.form, obj=user)
        if form.validate_on_submit():
            data = form.data
            user.set(**data)
            user.save()
            flash("Your profile has been saved")
        else:
            flash("form did not validate on submit")
        return self.render('user/profile.html', form=form, data=user)

user_view.add_view(Profile(name='Profile', url='profile'))

提交表单时,wtforms不会报告任何错误(除非有任何错误)但验证不会返回到我的配置文件视图(else:分支始终执行)

尽管已经彻底扫描了烧瓶管理员文档,源代码和示例,但我无法找到这项工作.

任何人都可以建议我如何修复我的代码,或解决这个问题？

任何人都可以告诉我如何将css类分配给选择值.我想用小图像改变每个选项的背景,那么我怎么能用wtforms和css做呢？

class RegisterForm(Form):
    username = TextField('username', [validators.Length(min=3, max=50), validators.Required()])
    img_url = SelectField('avatar', 
            choices=[('static/images/avatars/1.jpg', '1'), 
                ('static/images/avatars/2.jpg', '2'),
                ('static/images/avatars/3.jpg', '3'), 
                ('static/images/avatars/4.jpg', '4'),
                ('static/images/avatars/5.jpg', '5'), 
                ('static/images/avatars/6.jpg', '6'),
                ('static/images/avatars/7.jpg', '7'), 
                ('static/images/avatars/8.jpg', '8'),
                ('static/images/avatars/9.jpg', '9'), 
                ('static/images/avatars/10.jpg','10')])
