当我发帖时，它显示这个错误字段“id”期望一个数字，但得到了“d”。注意：帖子已创建，但我收到此错误

Question

我已经尝试了很多方法来解决这个问题，但它们都不起作用，这就是为什么我想在这里问比我更好的人。我试过使用 slug 字段它没有显示，但我想在它开始显示错误时使用 id。注意：帖子创建得非常好，然后显示此错误，但帖子已发布。我尝试使用前端的表单发布帖子

让我展示一些代码 视图.py

def blogpost(request):
    if request.method == "POST":
        form = BlogPostForm(request.POST, request.FILES)
        if form.is_valid():
            form.instance.creator = request.user
            form.save()  # ← no commit=False
            messages.success(request, f'Hi, Your Post have been sent for review and would be live soon!')
            return redirect('blog:home')
    else:
        form = BlogPostForm()

    context = {
        'form': form
    }
    return render(request, 'blog/AddPost.html', context)

# this is the blog list view
def blog_list(request):
    posts = Blog.objects.filter(status='published').order_by('-created')
    categoriess = Category.objects.all()

    context = {
        'posts': posts,
        'categories': categoriess,
    }
    return render(request, 'blog/bloghome.html', context)

#this is the blog detail view
def blog_detail(request, post_id):
    post = get_object_or_404(Blog, id=post_id)
    # post = Blog.objects.filter(slug=blog_slug)
    categories = Category.objects.all()
    comments = post.comments.filter(active=True)
    new_comment = None
    if request.method == "POST":
        comment_form = CommentForm(request.POST)
        if comment_form.is_valid():
            new_comment = comment_form.save(commit=False)
            new_comment.post = post
            new_comment.name = request.user
            new_comment.save()
    else:
        comment_form = CommentForm()

    context = {
        'post': post,
        'comments': comments,
        'comment_form': comment_form,
        'new_comment': new_comment,
        'categories': categories,
    }
    return render(request, 'blog/blog-details.html', context)

forms.py

class BlogPostForm(forms.ModelForm):
    image = forms.ImageField(widget=forms.ClearableFileInput(attrs={'multiple': True}), required=True)
    # content = forms.CharField(widget=forms.Textarea(attrs={'class': 'input is-medium'}), required=True)
    tags = forms.CharField(widget=forms.TextInput(attrs={'class': 'input is-medium'}), required=True)

    class Meta:
        model = Blog
        fields = ('title', 'content', 'image', 'category', 'tags')

addpost.html

<form action="" method="POST" enctype="multipart/form-data">
                            {% csrf_token %}
                            {{form|crispy}}
                        <div class="form-group">
                            <button class="btn theme-bg rounded" type="submit">Send Message</button>
                        </div>
                        </form>

urls.py

from django.urls import path
from . import views


app_name = 'blog'

urlpatterns = [
    path('', views.blog_list, name="home"),
    # path('post/<uuid:posts_id>', views.blog_detail, name="blog-details"),
    path('<uuid:post_id>', views.blog_detail, name='blog-details'),
    path('post/categories/<slug:category_slug>', views.category, name="category"),
    path('post/tags/<slug:tag_slug>', views.tag, name="tags"),
    path('post/create/', views.blogpost, name="add-post"),
]

任何帮助将不胜感激

Answer 1

将 urls.py 更改为 path('category/<int:int_name>/', views.CategoryView, name='category'), 这应该工作
