燒瓶render_template將不會發送varriables

，所以這是我的代碼燒瓶render_template將不會發送varriables

@auth.route("/",methods=["POST","GET"]) 
def index(): 
    form=LoginForm() 

return render_template("index.html",form=form)

，這是我的login.html文件：

<form action="http://127.0.0.1:5000/auth/res" method="post">  
    {{form.csrf_token}} 
    {{form.username}} 
    {{form.password}} 
    <input type="submit" value="submit" name="submit" /> 
    <form/>

，這是我的資源路徑：

@auth.route("/res",methods=["POST","GET"]) 
def res(): 
    form=LoginForm() 
    if form.validate_on_submit(): 
     return render_template("admin.html") 
    else: return render_template("index.html")

並且每當我運行我的應用程序，我得到這個錯誤：

* Running on http://127.0.0.1:5000/ 
127.0.0.1 - - [28/Oct/2017 22:41:10] "GET /auth/ HTTP/1.1" 200 -

爲什麼在'指數return語句（）'不縮進？ – gommb

對不起，這是miastake，當我在這裏複製我的代碼xD，但我的代碼是好的 –

我相信問題是，你不及格里面的res()

這應該修復它爲形式的可變進的index.html：

@auth.route("/res",methods=["POST","GET"]) 
def res(): 
    form=LoginForm() 
    if form.validate_on_submit(): 
     return render_template("admin.html") 
    else: return render_template("index.html", form=form)

thnx這固定它xD，但更多的問題是，vlidate_on_submit是不是真的？ –

你從哪裏得到'LoginForm（）'？ – gommb
