get_absolute_url 오류 해결 방법
미해결
.html {% for c in categories %} <li> <a href ="{{c.get_absolute_url}}" class ="{% if current_category.slug == c.slug %}active{% endif %}" > {{c.name}} </a> </li> {% endfor %} 을 이렇게 넣고... 서버 돌렸을 때 해당 페이지에서 계속 아래와 같이 뜹니다. NoReverseMatch at /정보/학습후기/ Reverse for 'page_category' not found. 'page_category' is not a valid view function or pattern name. 이라고 뜹니다..ㅠ 오류가 발생한 부분은 보니 여기인데... <a href=" {{c.get_absolute_url}} " class="{% if current_category.slug == c.slug %}active{% endif %}">{{c.name}}</a> models.py class Category(models.Model): city = models.CharField( max_length = 20 , db_index = True ) name = models.CharField( max_length = 20 , db_index = True ) phoneNumberRegex = RegexValidator( regex = r'^01([0|1|6|7|8|9]?)-?([0-9]{3,4})-?([0-9]{4})$' ) phone = models.CharField( validators =[phoneNumberRegex] , max_length = 13 , unique = True ) class_date = models.IntegerField( blank = True ) slug = models.SlugField( max_length = 20 , db_index = True, unique = True, allow_unicode = True ) class Meta: ordering = [ 'name' ] verbose_name = 'category' verbose_name_plural = 'categories' def __str__ ( self ): return self .name def get_absolute_url ( self ): return reverse( 'page44:page_category' , args =[ self .slug]) views.py from django.shortcuts import render , get_object_or_404 from .models import * def page4_in_category (request , category_slug= None ): current_category = None categories = Category.objects.all() page4 = Page4.objects.all() if category_slug: current_category = get_object_or_404(Category , slug =category_slug) page4 = page4.filter( category =current_category) return render(request , 'page4/page4.html' , { 'current_category' : current_category , 'categories' : categories , 'page4' : page4 , }) urls.py from django.urls import path from .views import * app_name = 'page44' urlpatterns = [ path( ' 학습후기 /' , page4_in_category , name = ' 학습후기 ' ) , path( '<slug:category_slug>' , page4_in_category , name = 'page_category' ) , path( ' 고객센터 /' , page5Views , name = ' 고객센터 ' ) , ] app_name name 설정 했고.. get_absolute_url부분에서 reverse 부분도 딱히 문제가 없는데.. 어디가 문제일까요?? admin에서 값은 넣었습니다! ㅠㅠ
