如何調試燒瓶BuildError

我想調試燒瓶0.8應用程序中的BuildError。在嘗試呈現多步表單的第2部分時，函數personal_open_account()中發生錯誤。第1步呈現表格，如果已驗證，則執行
return redirect(url_for('personal_open_account', step='2'))。也就是說，它自稱，但是有一個新的step參數。第1步成功完成，並在表單驗證（我可以看到一個打印語句我把），但我隨後立即收到BuildError：如何調試燒瓶BuildError

功能本身看起來像：

@app.route('/personal/save/<product_type>/<slug>/open-account', methods=['GET', 'POST']) 
def personal_open_account(product_type, slug):

從查看代碼可以很容易地推斷出，product_id和slug參數並未在隨後的調用中提供。

@app.route('/personal/save/<product_type>/<slug>/open-account'是創建API的錯誤方法。在這裏，您有兩個連續的/<product_type>/<slug>/識別符，這是路由器不能接受的。嘗試改寫這樣的路線，如@app.route('/personal/save/<product_type>/slugs/<slug>/open-account'。
