将提交表单的用户存储到同一个表中？

Question

我正在寻找存储负责表单提交的用户名称的最可取的方法，以便我可以轻松地按用户名组织他们提交的表单，就像每个用户的“帐户设置”一样。

我已经搜索过，但解决方案非常分散，所有关于此的帖子都指的是旧版本以及每个 Django 版本中更改的最佳解决方案。我仍在学习 Django 的基础知识，这可能无济于事。

这是我的views.py：

def add(request):
    title = 'Add Reddit Account'
    # ADD FORM
    form = AddRedditForm(request.POST or None)
    instance = form.save(commit=False)
    instance.user = request.user
    instance.save()
    if request.method == "POST":
        print(request.POST)

    context = {
        "form": form,
        "title": title,
        "user": instance.user
    }
    return render(request, "addreddit/add.html", context)

还有我的models.py：

from django.db import models

class Account(models.Model):
    user_name = models.CharField(max_length=20)
    password = models.CharField(max_length=18)
    secret = models.CharField(max_length=100)
    tag = models.CharField(max_length=20, blank=True)
    timestamp = models.DateTimeField(auto_now_add=True, auto_now=False)
    user = models.ForeignKey('auth.User', null=True)

    def __str__(self): #Python 3.3 is __str__
        return str(self.user)
        return self.user_name
        return self.password
        return self.secret
        return self.tag
        return self.timestamp

最后，forms.py 是相关的：

from django import forms
from .models import Account

class AddRedditForm(forms.ModelForm):
    class Meta:
        model = Account
        fields = ['user_name','password','secret','tag']
    user_name = forms.CharField(required=True)
    password = forms.CharField(widget=forms.PasswordInput,required=True)
    secret = forms.CharField(required=True)
    tag = forms.CharField(required=False)

这似乎工作得很好，除了保存在表单中的唯一是用户，而不是其他信息。

建议编辑：

from django.conf import settings
from django.core.mail import send_mail
from django.shortcuts import render, redirect
from .forms import AddRedditForm


# Create your views here.
def add(request):
    title = 'Add Reddit Account'
    # ADD FORM
    if request.method == "POST":
        form = AddRedditForm(request.POST or None)
        print(request.POST)
        if form.is_valid():
            instance = form.save(commit=False)
            instance.user = request.user
            instance.save()
            return redirect('addreddit/add') 

    context = {
        "title": title,
        "user": request.user,  # not available if you haven't submitted the form
        "form": form
        }
return render(request, "addreddit/add.html", context)

即使请求方法不是 POST，您也在该视图中做了很多工作来保存表单数据。在这种情况下，当您发出 GET 请求时，将保存一个表单实例，其中仅填充了 .user 字段。您也没有验证表单，这是一个有用的 Django 内置功能。试试这个：

def add(request):
    title = 'Add Reddit Account'

    if request.method == 'POST':
        form = AddRedditForm(request.POST)
        if form.is_valid():
            instance = form.save(commit=False)
            instance.user = request.user
            instance.save()
            return redirect('addreddit/add')  # or whatever named URL this is
    else:
        form = AddRedditForm()

    context = {
        "form": form,
        "title": title,
        "user": instance.user  # not available if you haven't submitted the form
    }
    return render(request, "addreddit/add.html", context)

在 GET 请求中，instance.user 将给出名称错误。我想它只是为了调试。否则，您仍然可以访问request.user。

我建议的另一个修改是 POST 之后的重定向，这样刷新页面就不会意外地重新提交表单。通过导入得到这个：

from django.shortcuts import redirect

ModelForm 不需要您重新定义字段。我会重写你的 forms.py 来反映这个事实。

class AddRedditForm(forms.ModelForm):
    class Meta:
        model = Account
        fields = ['user_name','password','secret','tag']
