D16 文件创建页 Create doc

先做了一个简易的文件创建页面
doc_info/views.py
设定成用get载入http://127.0.0.1:8000/doc/create/
就显示文件创建页的表单

如果是post载入
就执行资料创建还有重新转址到使用者个人文件页
render: 是将资料从这个view传送给指定的html然後呈现出来
从create的view里面return render到 user list.html
跟从user list的view里面return render到 user list.html 结果可能不一样
因为个别view里面传送出去的资讯可能不同
redirect: 等於是重新载入特定网址
此处doc_id不用指定因为会自行创建

@login_required
def doc_create(request):
    if request.method == "POST":
        user_id = request.user.id
        doc_create_date = datetime.now()
        doc_title = request.POST.get('title','')
        doc_remark = request.POST.get('remark','')
        upload_file = request.FILES.get('upload_file','')
        doc = doc_warehouse(
            create_date = doc_create_date,
            user_id = user_id,
            title = doc_title,
            remark = doc_remark,
            upload_file = upload_file,
        )
        doc.save()
        user_profile = get_object_or_404(UserProfile, user=request.user)
        user_profile.phone_number = request.POST.get('phone_number','')
        user_profile.save()
        return redirect('/doc/user/list')
    else:
        user = request.user
        Doc_warehouse = doc_warehouse.objects.filter(user_id=user.id)
        form = CreateForm()
        context = {
            'form': form
        }
        return render(request, 'doc/create.html', context)

网址就一样简单明了
doc_info/urls.py

urlpatterns = [
    path('doc/create/', views.doc_create, name='create'),
]

action保持""，在summit後会传送回本页
在测试的时候可以改成{% url 'doc_info:test' %}传送到test将request的资讯都列出来
如果使用者有手机就列出手机
没有手机就强制他一定要输入手机 送出资料後会存到使用者profile
templates/create.html
