NikUvolen's questions

我正在使用来自 YouTube 的视频和 websocket 创建聊天，一切都会很好，但是当我使用 websocket 编写类本身并导入模型进行连接时，会出现有关注册此模型的错误。我已经完成了所有内容，检查了 INSTALLED_APPS，并尝试在模型中的 Meta 中指示应用程序，但没有任何帮助。

问题在于模型本身在此文件中的导入，因为在其他文件中一切正常。这是日志：

    )
RuntimeError: Model class apps.chat.models.ChatGroup doesn't declare an explicit app_label and isn't in an application in INSTALLED_APPS.

这是有问题的文件本身：

import json
from channels.generic.websocket import WebsocketConsumer
from django.shortcuts import get_object_or_404

from .models import GroupMessage, ChatGroup

class ChatroomConsumers(WebsocketConsumer):
    def connect(self):
        self.user = self.scope['user']
        self.chatroom_name = self.scope['url_route']['kwargs']['chatroom_name']
        self.chatroom = get_object_or_404(ChatGroup, group_name=self.chatroom_name)
        self.accept()

    def receive(self, text_data):
        text_data_json = json.loads(text_data)
        body = text_data_json['body']

        message = GroupMessage.objects.create(
            body = body,
            author = self.user,
            group = self.chatroom
        )

好吧，模型本身：

class ChatGroup(models.Model):
    group_name = models.CharField(max_length=128, unique=True)

    def __str__(self):
        return self.group_name

好吧，从设置连接asgi

ASGI_APPLICATION = 'webProject.asgi.application'

已安装的应用程序：

INSTALLED_APPS = [
    "daphne",
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'crispy_forms',
    "crispy_bootstrap5",
    'debug_toolbar',
    "django_htmx",

    'mainMenu.apps.MainMenuConfig',
    'novella.apps.NovellaConfig',
    'authenticate.apps.AuthenticateConfig',
    'quiz.apps.QuizConfig',
    'chat.apps.ChatConfig'
]

我将非常感谢任何建议）

我在网站上写授权部分，js代码可以正常工作，但是当带有表单的页面更新时，输入的值仍然存在，并且js没有为输入的输入添加一个类价值。我更像是一个支持者，所以我希望你戳我的鼻子，怎么了：D

正常形式状态：

更新错误：

部分html表单：

<form id="signin-form" action="" method="POST" class="form form-sign_in" value="sign_in">
    {% csrf_token %}
    <div class="form-group">
         <label for="">Username<span class="req">*</span></label>
         {{ sign_in_form.username }}
    </div>
    <div class="form-group">
         <label for="">Password<span class="req">*</span></label>
         {{ sign_in_form.password }}
    </div>
    <button class="form-button" type="submit" name="submit" value="sign_in">Sign in</button>
</form>

js代码（jquery，因为我主要是从网上拿的）：

$('.form').find('input, textarea').on('keyup blur focus', function (e) {

var $this = $(this),
    label = $this.prev('label');

if (e.type === 'keyup') {
    if ($this.val() === '') {
        label.removeClass('active highlight');
    } else {
        label.addClass('active highlight');
    }
} else if (e.type === 'blur') {
    if ($this.val() === '') {
        label.removeClass('active highlight');
    } else {
        label.removeClass('highlight');
    }
} else if (e.type === 'focus') {
    if ($this.val() === '') {
        label.removeClass('highlight');
    } else if ($this.val() !== '') {
        label.addClass('highlight');
    }
}

});

$('.tab a').on('click', function (e) {

    e.preventDefault();

    $(this).parent().addClass('active');
    $(this).parent().siblings().removeClass('active');

    target = $(this).attr('href');

    $('.tab-content > div').not(target).hide();

    $(target).fadeIn(600);
});

UPD：以防万一，这是css：

label {
    position: absolute;
    transform: translateY(6px);
    color: rgba(256, 256, 256, 0.6);
    left: 13px;
    transition: all 0.25s ease;
    -webkit-backface-visibility: hidden;
    pointer-events: none;
    font-size: 22px;
}

label .req {
    margin: 2px;
    color: #1ab188;
}

label.active {
    transform: translateY(42px);
    left: 2px;
    font-size: 14px;
}
label.active .req {
    opacity: 0;
}

label.highlight {
    color: #ffffff;
}

input,
textarea {
  font-size: 22px;
  display: block;
  width: 100%;
  height: 100%;
  padding: 5px 10px;
  background: none;
  background-image: none;
  border: 1px solid #a0b3b0;
  color: #ffffff;
  border-radius: 0;
  transition: border-color 0.25s ease, box-shadow 0.25s ease;
}

input:focus,
textarea:focus {
  outline: 0;
  border-color: #1ab188;
}

textarea {
  border: 2px solid #a0b3b0;
  resize: vertical;
}

我正在写一份调查问卷，保存用户的问题/答案时出现问题。我不知道如何在代码中为用户创建一个单独的表（当然，除非他还有一个表）以便代码可以使用它。我将非常感谢您的解释。

以下是此类表的一些示例字段：

class UserTable(peewee.Model):
    """База данных пользователя"""

    id = peewee.IntegerField(unique=True)
    # вопрос 1
    q1 = peewee.CharField(null=True)
    # вопрос 2
    q2 = peewee.CharField(null=True)
    # вопрос 3
    q3 = peewee.CharField(null=True)
    # вопрос 4
    q4 = peewee.CharField(null=True)

    class Meta:
        database = database

如何重写和使用这个GetSprite()pod Dictionary<ItemType, Sprite>，以免为每个精灵使用单独的字段：

public Sprite GetSprite()
{
    switch (itemType)
    {
         default:
         case ItemType.Apple:
             return ItemAssets.Instance.AppleSprite;
         case ItemType.Bacon:
             return ItemAssets.Instance.BaconSprite;
         case ItemType.Bread:;
             return ItemAssets.Instance.BreadSprite;
         case ItemType.Fish:
             return ItemAssets.Instance.FishSprite;
         case ItemType.Steak:
             return ItemAssets.Instance.SteakSprite;
         case ItemType.Onion:
             return ItemAssets.Instance.OnionSprite;
    }
}

这个类也有精灵：

public class ItemAssets : MonoBehaviour
{
    public static ItemAssets Instance { get; private set; }

    private void Awake()
    {   
         Instance = this;
    }

    public Transform pfItemWorld;

    public Sprite AppleSprite;
    public Sprite BaconSprite;
    public Sprite BreadSprite;
    public Sprite FishSprite;
    public Sprite SteakSprite;
    public Sprite OnionSprite;

}
