我正在切换到peewee for flask app时出错。 “peewee.IntegerField对象有没有属性“标志”

时间：2017-06-22 19:37:07

标签： python flask wtforms peewee flask-peewee

我开始从使用烧瓶应用程序中的标准基本SQL切换到使用peewee并且我得到一个奇怪的错误，我似乎无法找到任何信息。我的端点工作正常，但当我尝试进入登录页面时，我得到“jinja2.exceptions.UndefinedError：'peewee.IntegerField object'没有属性'flags'”

这似乎与wtforms和peewee有些奇怪的互动，但我似乎无法找到类似的问题。提前致谢。

注意一切都在一个文件中

我的模特：

class pipelineForm(FlaskForm):
    pipeline = IntegerField('Pipeline ID')
class Process(Model):
    pipeline_id = IntegerField()
    process_name= CharField(null = True)
    log= CharField(null = True)
    exit_code= IntegerField()
    started= CharField(null = True)
    finsihed= CharField(null = True)

    class Meta:
        database=db

登陆终点：

@app.route('/bloodhound', methods=['GET','POST'])
def index():
    form =pipelineForm()
    print(form.errors)
    if form.validate_on_submit():
        print(str(form.pipeline.data))
        return redirect(url_for('.display', pipelineId=form.pipeline.data))#'<h1>' + str(form.pipeline.data) + '</h1>'
    return render_template('index.html',form=form)

根据您的错误消息此字段

class pipelineForm(FlaskForm):
    pipeline = IntegerField('Pipeline ID')

的类型为pewee.IntegerField，您希望它成为IntegerField类型的WTForms。如果您在同一个文件中同时拥有这两个类，则需要：

import pewee
import wtforms.fields
class pipelineForm(FlaskForm):
    pipeline = fields.IntegerField('Pipeline ID')
class Process(Model):
    pipeline_id = pewee.IntegerField() # and so on
