如何在django中提交數據?

[英]How can i submit data in django?

我想要3頁。 一個顯示某個目錄的某些用戶名,稱為“靜態”(您將在我的views.py中看到它)。 如果用戶想要添加用戶,則按下2個“添加”按鈕中的一個...如果他這樣做,他將進入第二頁,在那里他可以輸入用戶名和密碼,並可以通過“提交”進行確認“按鈕。 然后數據應保存在“靜態”文件夾中。 之后,他被定向到另一個網站,在那里它說“注冊成功”,3秒后他回到index.html查看結果。 在django文檔中,我認為它們只是以另一種方式幾乎相同xP https://docs.djangoproject.com/en/1.5/intro/tutorial04/我只是不知道如何將他們的示例分配給我的項目:/她是我的觀點:

from django.shortcuts import render
import os


def index(request):
        os.chdir("/home/ubuntu/newproject/static")
        files = []
        for file in os.listdir("."):
            files.append(file)
        return render(request, 'sslcert/index.html', dict(files = files))

def adduser(request):
        return render(request, 'sslcert/adduser.html')

def redirect(request):
    return render(request, 'sslcert/redirect.html')

這是第一個網站的模板:

<head>
 {% block title %}
  <h3>
   Following users exist in the folder 'static' :
  </h3>
 {% endblock %}
</head>

<body>
 <table border = "0" width = "100%" align = "left">
  <tr>
   <td align = "right">
    <form action = "adduser.html" method = "post">{% csrf_token %}
    <input type = "submit" name = "form" style = "width:8%" value = "Add">
   </td>
  </tr>
   {% for file in files %}
  <tr>
   <td align = "left"> {{ file }} </td>
  </tr>
   {% endfor %}
  <tr>
   <td align = "right">
    <form action = "adduser.html" method = "post">{% csrf_token %}
    <input type = "submit" name = "form" style = "width:8%" value = "Add">
    </form>
   </td>
  </tr>
 </table>
</body>

這是我的第二個網站的模板:

<head>
 {% block title %}
  <h2 align = "middle" >
   <u>Add a user</u>
  </h2>
 {% endblock %}
</head>

<body>
 <table border = "0" width = "100%">
  <tr>
   <td>
    <p>Username:</p>
    <input type = "text" name = "" value = "" />
   </td>
  </tr>
  <tr>
   <td>
    <p>Password:</p>
    <input type = "password" name = "" value = "" />
   </td>
  </tr>
  <tr>
   <td>
    <form action = {% url 'sslcert:redirect' %} method = "post"> {%csrf_token %}
    <input type = "submit" value = "Submit">
    </form>
   </td>
  </tr>
 </table>
</body>

這是重定向網站的模板:

<head>
 <meta http-equiv = "refresh" content = "3; URL=http://10.0.3.79:8000/sslcert/">
 {% block title %}
  <h4>
   Registration successful !
  </h4>
 {% endblock %}
</head>

我閱讀了文檔,我發現了這個代碼示例:

from django.shortcuts import get_object_or_404, render
from django.http import HttpResponseRedirect, HttpResponse
from django.core.urlresolvers import reverse
from polls.models import Choice, Question
# ...
def vote(request, question_id):
    p = get_object_or_404(Question, pk=question_id)
    try:
        selected_choice = p.choice_set.get(pk=request.POST['choice'])
    except (KeyError, Choice.DoesNotExist):
        # Redisplay the question voting form.
        return render(request, 'polls/detail.html', {
            'question': p,
            'error_message': "You didn't select a choice.",
        })
    else:
        selected_choice.votes += 1
        selected_choice.save()
        # Always return an HttpResponseRedirect after successfully dealing
        # with POST data. This prevents data from being posted twice if a
        # user hits the Back button.
        return HttpResponseRedirect(reverse('polls:results', args=(p.id,)))

我認為這條線可能會有所幫助:

try:
            selected_choice = p.choice_set.get(pk=request.POST['choice'])

但我真的不知道如何將它分配給我的項目:/我已經在模型中創建了2個類,名稱為“Username”和“Password”。 請大家幫幫我:(

非常感謝幫助:)

好吧,當瀏覽器首先填寫表單時,您正在發送GET請求。 否則,如果您向服務器發送信息則需要發送POST請求。 看一下文檔

好吧,我自己找到了答案......令人沮喪的是,我浪費了這么多時間,但我在adduser.html(第二頁)中有點盲目xP我只是在提交按鈕周圍...只有提交的東西是csrf_token。 現在它看起來像這樣,它也提交用戶名和密碼:

<!DOCTYPE html>
<html>
 <head>
  {% block title %}
   <h2 align = "middle" >
    <u>Add a user</u>
   </h2>
  {% endblock %}
 </head>

 <body>
 <form action = "{% url 'sslcert:redirect' %}" method = "post">{% csrf_token %}
  <table border = "0" width = "100%">
   <tr>
    <td>
     <p>Username:</p>
     <input type = "text" name = "username" value = "" />
    </td>
   </tr>
   <tr>
    <td>
     <p>Password:</p>
     <input type = "password" name = "password" value = "" />
    </td>
   </tr>
   <tr>
    <td>
     <input type = "submit" value = "Submit">
    </td>
   </tr>
  </table>
 </form>
 </body>
</html>

我改變了我的觀點。像這樣:

from django.shortcuts import render
import os

def index(request):
        os.chdir("/home/ubuntu/newproject/static")
        files = []
        for file in os.listdir("."):
            files.append(file)
        return render(request, 'sslcert/index.html', dict(files = files))

def adduser(request):
        return render(request, 'sslcert/adduser.html')

def redirect(request):
        username = request.POST['username']
        password = request.POST['password']

        print username
        print password


        return render(request, 'sslcert/redirect.html')
