Question

用户登录后，用户可以提交表单。单击“提交”按钮，数据将存储在数据库中，但如何将此信息连接到提交用户。

我需要代码以及新db

的结构

有点从django开始。任何帮助将不胜感激!!!

我已将用户作为外键包含在CustomizeRequest模型中，但现在我该如何填写此信息？

完全情景：用户登录后，一旦他来到contactUs.html，他就会提交一份表格，告知旅客人数。该号码存储在DB中。但是现在如何将这些数字中的每一个连接到提交的用户？

models.py

class CustomizeRequest(models.Model):
    user = models.ForeignKey(User)
    travellers = models.CharField(max_length=2)

    def __str__(self):
        return self.travellers

contactUs.html

<form method="POST" class="form-horizontal">
{% csrf_token %}
<div class="btn-group" data-toggle="buttons">
{% for radio in crform.travellers %}
    <label class="btn btn-default {% if radio.choice_label = '1'   %}active{% endif %}" for="{{ radio.id_for_label }}">
      {{ radio.choice_label }}
      {{ radio.tag }}
    </label>
{% endfor %}
</div>
<button type="submit" class="btn btn-default btn-block btn-warning">SUBMIT</button>
</form>

views.py

def contactUs(request):
    if request.method=="POST":
        form = CustomizeRequestForm(request.POST)
        form.save()
    else:
        form = CustomizeRequestForm()
    context_dict = {'form': form}
    return render(request, 'tour/contactUs.html', context_dict)

Answer 1

已记录的用户可用作request.user属性。您可以使用form.save(commit=False)技巧获取未保存的模型实例，设置user字段，然后将实例保存到数据库：

from django.contrib.auth.decorators import login_required
from django.shortcuts import redirect, render

@login_required
def contactUs(request):    
    if request.method == "POST":
        form = CustomizeRequestForm(request.POST)
        if form.is_valid():
            customize_request = form.save(commit=False)
            customize_request.user = request.user
            customize_request.save()
            return redirect('.')
    else:
        form = CustomizeRequestForm()
    context_dict = {'form': form}
    return render(request, 'tour/contactUs.html', context_dict)

Answer 2

基于catavaran答案（检查表格是否有效）：

from django.contrib.auth.decorators import login_required
from django.shortcuts import redirect, render

@login_required
def contactUs(request):    
    form = CustomizeRequestForm(data=request.POST or None)

    if request.method == "POST":
        if form.is_valid():
             customize_request = form.save(commit=False)
             customize_request.user = request.user
             customize_request.save()
             return redirect('.')
        else:
             pass # could add a notification here

    context_dict = {'form': form}
    return render(request, 'tour/contactUs.html', context_dict)
