通過引用將數據添加到wtforms

Question

我想用我的數據庫中的數據預先加載wtforms中的表單數據而不知道列名。

只要我知道我想要的列名，這項工作。

form.column.data=User.query.get(1).first().column 

我想要做的就是去了所有列像這樣：

for attr, value in User.query.get(1).__dict__.iteritems(): 
form.attr.data = value 

這樣做給我的錯誤：

AttributeError: 'EditUsersForm' object has no attribute 'attr' 

這裏是我的代碼的片段努力開始專門工作。

forms.py

class EditUsersForm(ModelForm): 
    class Meta: 
     model=User 
     exclude=['password_hash'] 

models.py

class User(db.Model): 
    id = db.Column(db.Integer, primary_key=True) 
    username = db.Column(db.String(32), index=True, unique=True) 
    password_hash = db.Column(db.String(128)) 
    email = db.Column(db.String(120), index=True, unique=True) 
    posts = db.relationship('Post', backref='author', lazy='dynamic') 
    #mobilitys = db.relationship('Mobility', backref='username', lazy='dynamic') 
    about_me = db.Column(db.String(140)) 
    last_seen = db.Column(db.DateTime) 

    def __repr__(self): # pragma: no cover 
     return '<user> %r' % (self.username) 

views.py

@app.route('/manpower_edit_users', methods=['GET', 'POST']) 
@login_required 
def manpower_edit_users(): 
    form=QueryAllUsers(request.form) 
    forms=EditUsersForm(request.form) 
    ''' 
    if forms.validate(): 
     print("validate") 
     print("forms.validate=",forms.validate) 
     flash("User added") 
    ''' 
    if request.method == "POST": 
     for attr, value in User.query.get(user_list).__dict__.iteritems(): 
      forms.attr.data=value 
    elif request.method == "GET": 
     for attr, value in User.query.get(1).__dict__.iteritems(): 
      forms.attr.data=value 
    return render_template('manpower_edit_users.html',title='Manpower Edit User', form=form, forms=forms) 

Answer 1

edit_user_form = EditUsersForm(obj = User.query.get(1)) 

可以填充從數據的表單。在WTForms文檔關鍵字參數obj說：

obj – If formdata has no data for a field, the form will try to get it from the passed object.
