为 Flask 应用程序切换到 peewee 时出错。 'peewee.IntegerField object' 没有属性 'flags'
Error as I'm switching to peewee for flask app. 'peewee.IntegerField object' has no attribute 'flags'
我开始从在我的烧瓶应用程序中使用标准的基本 SQL 切换到使用 peewee 并且我遇到了一个奇怪的错误，我似乎无法找到任何相关信息。我的端点工作正常，但当我尝试转到登录页面时，我得到 "jinja2.exceptions.UndefinedError: 'peewee.IntegerField object' has no attribute 'flags'"
这似乎是与 wtforms 和 peewee 的一些奇怪的交互，但我似乎找不到类似的问题。提前致谢。
注意所有内容都在一个文件中
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
着陆页的终点：

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>'
