如何在 Django 中为页面添加书签? [英] How to bookmark a page in Django?

问题描述

我正在尝试编辑一个 html 页面，以便登录用户可以收藏/收藏 video.id

I am trying to edit an html page so a logged in user can favorite / bookmark a video.id

这是.html文件

<td>
    <form method='POST' action="{% url 'researcher_view_app:favourite_post' video.id %}">
        {% csrf_token %}
        <input type='hidden' name='video' value={{ video.id }}>
        <button type='submit'>Bookmark</button>
    </form>
</td>

这是urls.py文件

path('<int:fav_id>/favourite_post', views.favourite_post, name='favourite_post'),

这是view.py文件

def favourite_post(request, fav_id):
    video = get_object_or_404(Video, id=fav_id)
    if request.method == 'POST':
        video.

   return render(request, 'researcher_view_app/%s' % fav_id)

推荐答案

• 首先修改具有用户模型的 models.py

class ProjectUser(AbstractUser):
    images = models.ManyToManyField(Images)

    def __str__(self):
        return self.email

• 在 .html 文件中添加以下内容:
• In the .html file add the following:

{% for image in available_images %}
/* show image */
<form method='post' action="{% url 'user-image-add' %}">
 {% csrf_token %}
 <input type='hidden' name='image' value={{image.id}}>
 <button type='submit'>bookmark</button>
</form>
{% endfor %}

• 在您的 views.py 中添加以下方法
• In your views.py add the following method

def user_image_add(request):
    user_image_form = ImageForm(request.POST or None)
    if request.method == 'POST' and user_image_form.is_valid(): 
         request.user.images.add(user_image_form.cleaned_data['image'])
         return JsonResponse(status=200)
    raise Http404()

• 在您的添加中创建一个 forms.py 文件并添加以下内容:
• Create a forms.py file in your add and add the following:

class ImageForm(forms.Form):
    image = forms.ModelChoiceField(queryset=Images.objects.all())

要显示那些带有书签的图像，您可以像上面的代码一样遍历 request.user.images(它为您提供图像的 QS).

To show those bookmarked images you can just iterate over request.user.images (it gives you a QS of Images) similar to code above.

• 在 urls.py 中添加以下内容:
• In the urls.py add the following:

path('user-image-add/', views.user_image_add, 'user-image-add')

• 在models.py中，在用户模型中添加一个方法，用于在视频被添加书签时获取布尔值

def is_bookmarked(self, video_id): 
    return self.bookmarked_videos.filter(id=video_id).exists()

同样可以将 is_bookmarked 添加到接受 user_id 并检查 video.projectuser_set 的 Video 模型.

simirlarly is_bookmarked can be added to Video model accepting user_id and checking video.projectuser_set.

并将以下内容添加到用户为视频添加书签的 .html 文件中

And add the following to your .html file where users bookmarked a video

`{% if video.is_bookmarked %}`

• 删除不需要的 UserProfile.只需确保在视图上下文中具有所需的实例.

• Delete the UserProfile as you do not need it. Just make sure to have needed instance in context of view.
