我已经用尽了所有尝试为此设置解决方案的途径,但我目前对Python和Django的了解只能让我到目前为止。
我正在创建一个基本的票务系统,CreateView过去一直工作,直到我创建了一个Profile模型,然后将Ticket模型分成了自己的应用程序。当我重构我的代码时,已经创建了几张票,这就是我知道ListView工作的原因,DeleteView和DetailView一样工作。 CreateView一直有效,直到我点击保存按钮。
我的观点和模型如下;我希望有人可以帮我解决这个问题。
票证模型
from django.db import models
from django.contrib.auth.models import User
....
from qcapp.models import Profile
class Ticket(models.Model):
# Relations
user = models.ForeignKey(Profile, on_delete=models.CASCADE, related_name="tickets", verbose_name="user")
# Attributes
title = models.CharField(max_length=250, verbose_name="Title", help_text="Enter a Ticket Title")
color = models.CharField(max_length=7,
default="#ffffff",
validators=[RegexValidator("(^#[0-9a-fA-F]{3}$)|(^#[0-9a-fA-F]{6}$)")],
verbose_name="Color",
help_text="Enter the hex color code, like #ccc or #cccccc")
description = models.TextField(max_length=1000)
created_date = models.DateTimeField(default=timezone.now, verbose_name='Created Date')
created_by = models.ForeignKey(User, related_name='created_by_user')
# Attributes
# Object Manager
objects = managers.ProjectManager()
# Meta and String
class Meta:
verbose_name = "Ticket"
verbose_name_plural = "Tickets"
ordering = ("user", "title")
unique_together = ("user", "title")
def __str__(self):
return "%s - %s" % (self.user, self.title)
def get_absolute_url(self):
return reverse('ticket_detail', args=[str(self.id)])
故障单视图(仅限CreateView)
# -*- coding: utf-8 -*-
...
from django.views.generic import CreateView, UpdateView, DeleteView
...
from .models import Ticket
...
class TicketCreate(CreateView):
model = Ticket
template_name = "tickets/ticket_form.html"
fields = ['title', 'description']
def form_valid(self, form):
form.instance.created_by = self.request.user
return super(TicketCreate, self).form_valid(form)
...
个人资料模型(导入故障单模型)
from django.db import models
from django.conf import settings
from django.contrib.auth.models import User
from django.dispatch import receiver
from django.db.models.signals import post_save
from . import managers
class Profile(models.Model):
# Relations
user = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name="profile", verbose_name="user")
# Attributes
interaction = models.PositiveIntegerField(default=0, verbose_name="interaction")
# Attributes
# Object Manager
objects = managers.ProfileManager()
# Custom Properties
@property
def username(self):
return self.user.username
# Methods
# Meta and String
class Meta:
verbose_name = "Profile"
verbose_name_plural = "Profiles"
ordering = ("user",)
def __str__(self):
return self.user.username
@receiver(post_save, sender=settings.AUTH_USER_MODEL)
def create_profile_for_new_user(sender, created, instance, **kwargs):
if created:
profile = Profile(user=instance)
profile.save()
答案 0 :(得分:4)
您似乎需要在TicketCreate
函数的form_valid
课程中添加以下内容:
form.instance.user = Profile.objects.get(user=self.request.user)
让我知道这是否有效!
