如果字段名称与 slug 不同，则 Slugfield 不起作用

Question

晚上好，Django 对我来说是全新的，这是我的第一个问题。我正在尝试创建一个 Webapp。我正在使用 Django、Python 和 MariaDB。我创建了一个包含两个应用程序的项目，每个应用程序都有一个模型。在第一个中，我使用“slug”作为字段名称，一切正常。在第二个中，我想区分该字段，给出一个不同的名称 (bk_slug)，定义为 SlugField。我尝试使用相同类型的指令行并修改它们似乎不起作用的字段名称。我无法拥有正确的 URL（基于 Class 的 ListView）并且无法访问基于 Class 的 DetailView.... 在此先感谢您的支持。

models.py


    from django.db import models
    from django.conf import settings
    from django.utils import timezone
    from django.urls import reverse
    
    # book masterdata
    
    
    class Book(models.Model):
        bk_title = models.CharField("Book Title", max_length=100, 
            primary_key=True)
        bk_originaltitle = models.CharField("Book original Title", 
            max_length=100, blank=True)
        bk_author = models.CharField("Author", max_length=50)
        bk_editor = models.CharField("Editor", max_length=50)
        bk_editiondate = models.CharField("Book Edition date", 
            max_length=30)
        bk_recblocked = models.BooleanField("Book record blocked")
        bk_creator = models.ForeignKey(
            settings.AUTH_USER_MODEL, on_delete=models.PROTECT, 
            related_name='+', verbose_name="Created by")
        bk_creationdate = models.DateTimeField("Creation date", 
            auto_now=True)

        bk_modified = models.DateTimeField("Last modification date", 
            auto_now=True)
        bk_slug = models.SlugField(max_length=100, allow_unicode=True, 
            blank=True)

Answer 1

在您的 DetailView 中，您需要将 slug_field [Django-doc] 指定为 'bk_slug':

class BookDetailView(DetailView):
    model = Book
    <strong>slug_field = 'bk_slug'</strong>
    
    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        return context

在模型中，您将需要 slugify(…) [Django-doc] 名称，因此：

from django.utils.text import <strong>slugify</strong>

class Book(models.Model):
    # …

    def save(self, *args, **kwargs):
        if not self.bk_slug:
            <strong>self.bk_slug = slugify(self.title)</strong>
        return super().save(*args, **kwargs)

如果字段名称与 slug 不同，则 Slugfield 不起作用

Slugfield not working if field name is different from slug

django

url

slug
