即使使用“allow_unicode=True”，韩语中的 Slug 也无法在 Django 中工作

Question

I'm trying to make an automatic slug using the slugify in django.utils.text . The following are my code:

# models.py

from django.db import models
from django.contrib.auth.models import User
from django.utils.text import slugify

class Article(models.Model):
    title = models.CharField(max_length=100)
    slug = models.SlugField(allow_unicode=True)
    body = models.TextField()
    date = models.DateTimeField(auto_now_add=True)
    thumb = models.ImageField(default='default.png', blank=True)
    author = models.ForeignKey(User, default=None, on_delete=models.CASCADE)

    def save(self, *args, **kwargs):
        self.slug = slugify(self.title, allow_unicode=True)
        super().save(*args, **kwargs)

    def __str__(self):
        return self.title

# article_create.html

{% extends 'base.html' %}

{% block content %}
    <div class="create-article">
        <h2>Awesome New Article </h2>
        <form class='site-form' action="{% url 'articles:article_create' %}" method="POST" enctype="multipart/form-data">
            {% csrf_token %}
            {{ form.as_p }}
            <input type="submit" value="create">
        </form>
    </div>
{% endblock %}

# html template - article_lists.html

...
<a href="{% url 'articles:article_details' article.slug %}"></a>
...

I used the allowed_unicode=True in order to allow different languages to be used, but the following error comes up when I type in Korean in the title in the form:

The first underlined is the title of the article that I'm trying to post, and the second underline is the Django backend checking the slug, but I see that it doesn't recognize the Korean letters... I did what all the other similar StackOverflow, including putting the allow_unicode=True , but it's not working. What must be wrong here???

*edit: This is the urls.py code:

from django.urls import path
from . import views

app_name = 'articles'

urlpatterns = [
    path('', views.article_list, name="article_list"),
    path('create/', views.article_create, name="article_create"),
    path('<slug:slug>/', views.article_details, name='article_details'),
]

Answer 1

The error is showing what you defined in the urls.py file for the given route. You could change the route articles/?P<slug>... to include more than just [-a-zA-Z0-9_] . Then the reverse lookup should be able to match the slug.

Found out the reason to this! it wasn't working it was because of the urls.py

Before:

from django.urls import path
from . import views

app_name = 'articles'

urlpatterns = [
    ...
    path('<slug:slug>/', views.article_details, name='article_details'),
]

After:

from django.urls import path
from . import views

app_name = 'articles'

urlpatterns = [
    ...
    path('<slug>/', views.article_details, name='article_details'),
]

I had to change the <slug:slug> to <slug> ... I really don't know the reason why and maybe it's just for in Korean, but this was the right way for me.
