AttributeError: module 'courses.views' has no attribute 'search'

Question

我是 Django 初学者，正在根据 Youtube 教程在一个教育网站上工作。我的问题是我不知道我的错误在哪里。

原错误：

AttributeError: module 'courses.views' has no attribute 'search'

错误 2（当我在 urls.py 中用 views.search 注释行时出现）

In template C:\Users\Vusala\Desktop\smartedu_project\smartedu_original\templates\partials_base.html, error at line 0

Reverse for 'search' not found. 'search' is not a valid view function or pattern name.

下面是项目的一些代码。

urls.py

from django.urls import path
from . import views


urlpatterns = [
    path('', views.course_list, name="courses"),
    path('<slug:category_slug>/<int:course_id>', views.course_detail, name="course_detail"),
    path('categories/<slug:category_slug>', views.course_list, name="courses_by_category"),
    path('tags/<slug:tag_slug>', views.course_list, name="courses_by_tag"),
    #path('search/', views.search, name="search"),
]

views.py

from django.http import HttpResponse
from django.shortcuts import render
from . models import Course, Category, Tag

def course_list(request):
    courses = Course.objects.all().order_by('-date')
    categories = Category.objects.all()
    tags = Tag.objects.all()
    
    
    context= {
        'courses': courses,
        'categories': categories,
        'tags': tags
    }
    return render(request, 'courses.html', context)

def course_detail(request,category_slug, course_id):
    course = Course.objects.get(category__slug=category_slug, id=course_id)
   

    context = {
       
        'course' : course
    }

    return render(request, 'course.html', context)

我希望你能帮助我，让我摆脱这种绝望。

Answer 1

错误很明显，它表示在您的视图中没有名为搜索的函数

请考虑添加代码和错误不是它们的 img ..

第二个错误发生在这里

<form method="get" id="site-searchform" action="{% url 'search' %}">
    <div>
    <input class="input-text form-control" name="search" placeholder="Search keywords..." type="text">
    <input id="searchsubmit" value="Search" type="submit">
   </div>
</form>

在此表单中 course.html 表单操作设置为 {% url 'seaech '%} 只要删除这个表格，一切都会起作用

AttributeError: module 'courses.views' has no attribute 'search'
