我開始從在我的燒瓶應用程序中使用標準的基本SQL切換到使用peewee和得到一個奇怪的錯誤我似乎無法找到任何有關信息。我的終結點工作正常，但當我嘗試去登陸頁面時，我得到「jinja2.exceptions.UndefinedError：'peewee.IntegerField對象'沒有屬性'標誌'」錯誤，因爲我切換到peewee燒瓶應用程序。 'peewee.IntegerField對象'沒有屬性'標誌'
這似乎是一些奇怪的與wtforms和peewee但我似乎無法找到類似的問題。提前致謝。
注一切都在一個文件中
我的模型：
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
終點着陸頁：
@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)

完美！將pipeline = IntegerField（'Pipeline ID'）'改爲'pipeline = wtforms.IntegerField（'Pipeline ID'）'解決了我的問題。 – patrick1378
