如何使主题标签可点击并显示在Django的帖子中? [英] how can make hashtag clickable and show it in the post in Django?

问题描述

用户可以制作主题标签.现在，我想使主题标签可点击.贝娄是我的Hashtag的Models.py:

User can make hashtag. Now I want to make hashtag clickable. Bellow is my Models.py for Hashtag:

class Hashtag(models.Model):
    hashtagname     = models.CharField(max_length=3000, blank=True, null=True)
    hashtagcount    = models.IntegerField(null=True, blank=True)
    post_pk         = models.ManyToManyField(PostUser)
    atetime         = models.DateTimeField(auto_now_add=True)
    date            = models.DateField(auto_now_add=True)
    time            = models.TimeField(auto_now_add=True)
    user_pk         = models.IntegerField()

在我的views.py文件中，我获取了所有主题标签，并将其作为字典代码通过字典发送到html:

and in my views.py I get all the hashtags and send it by dictionary to html as bellow codes:

mosttrending     = Hashtag.objects.all().order_by('-hashtagcount')[:10]

并且我已经为所有帖子建立了模型

and already I have a model for all the Posts as bellow

class PostUser(models.Model):
    posttype        = models.CharField(max_length=3000, default='postuser')
    content         = models.TextField(null = True, blank= True)
    media_image     = models.FileField(null = True, blank= True)
    media_video     = models.FileField(null = True, blank= True)
    per_to          = models.CharField(max_length=300, null=True, blank=True, default='everyone')
    status          = models.CharField(max_length=3000, default='active')
    date            = models.DateField(auto_now_add=True)
    time            = models.TimeField(auto_now_add=True)
    datetime        = models.DateTimeField(auto_now_add=True)
    like            = models.IntegerField(null=True, blank=True)
    comment         = models.IntegerField(null=True, blank=True)
    share           = models.IntegerField(null=True, blank=True)
    user_pk         = models.IntegerField()

在带有for循环的html中，我得到了所有PostUser:

And in my html with a for loop I get all the PostUser:

{% for readposts in readposts %}
<p class="card-text">{{readposts.content|linebreaks}}</p>
{% endfor %}

如何为主题标签建立链接，当用户单击主题标签时，如何向用户显示所有帖子?

How Can I make the link for hashtag and when a user click on the hashtag show the user the all the post?

推荐答案

我在django应用中的文件夹名称templatetags中创建了app_extras.py和 init .py，然后在app_extras.py中编写了代码下面并且工作了

I made app_extras.py and init.py in a folder name templatetags in my django app then in the app_extras.py wrote the code bellow and worked

import re
from django import template
from django.utils.html import escape
from django.utils.safestring import mark_safe

register = template.Library()

def create_hashtag_link(tag):
    url = "/tags/{}/".format(tag)
    # or: url = reverse("hashtag", args=(tag,))
    return '<a href="{}">#{}</a>'.format(url, tag)


@register.filter(name='hashchange')
def hashtag_links(value):
    return mark_safe(
        re.sub(r"#(\w+)", lambda m: create_hashtag_link(m.group(1)),
               escape(value)))

然后在HTML中，我已经加载了app_extras.py

then in HTML I have loaded the app_extras.py

{% load app_extras %}

然后在我的循环html中，我调用了该函数

Then in my loop html I called the function

{% for readposts in readposts %}
<p class="card-text">{{readposts.content|hashchange|linebreaks}}</p>
{% endfor %}

还有我添加的urls.py

and also my urls.py I have added

url(r'^tags/(?P<tags>\w+)/$', views.tags, name='tags'),

然后当然是标签的视图，在这种情况下，我的视图是

then of course a view for tag which in this case my view is

def tags(request, tags):
      readpostsuser   = PostUser.objects.filter(content__icontains = tags).order_by('-pk')

return render(request, 'front/tags.html', {'readpostsuser':readpostsuser})
