[英]How can i submit data in django?
我想要3页。 一个显示某个目录的某些用户名,称为“静态”(您将在我的views.py中看到它)。 如果用户想要添加用户,则按下2个“添加”按钮中的一个...如果他这样做,他将进入第二页,在那里他可以输入用户名和密码,并可以通过“提交”进行确认“按钮。 然后数据应保存在“静态”文件夹中。 之后,他被定向到另一个网站,在那里它说“注册成功”,3秒后他回到index.html查看结果。 在django文档中,我认为它们只是以另一种方式几乎相同xP https://docs.djangoproject.com/en/1.5/intro/tutorial04/我只是不知道如何将他们的示例分配给我的项目:/她是我的观点:
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')
这是第一个网站的模板:
<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>
这是我的第二个网站的模板:
<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>
这是重定向网站的模板:
<head>
<meta http-equiv = "refresh" content = "3; URL=http://10.0.3.79:8000/sslcert/">
{% block title %}
<h4>
Registration successful !
</h4>
{% endblock %}
</head>
我阅读了文档,我发现了这个代码示例:
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,)))
我认为这条线可能会有所帮助:
try:
selected_choice = p.choice_set.get(pk=request.POST['choice'])
但我真的不知道如何将它分配给我的项目:/我已经在模型中创建了2个类,名称为“Username”和“Password”。 请大家帮帮我:(
非常感谢帮助:)
好吧,当浏览器首先填写表单时,您正在发送GET
请求。 否则,如果您向服务器发送信息,则需要发送POST
请求。 看一下文档 。
好吧,我自己找到了答案......令人沮丧的是,我浪费了这么多时间,但我在adduser.html(第二页)中有点盲目xP我只是在提交按钮周围...只有提交的东西是csrf_token。 现在它看起来像这样,它也提交用户名和密码:
<!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>
我改变了我的观点。像这样:
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')
