【问题描述】:
我尝试学习 Django,我确信我的问题很愚蠢,但我认为每个初学者都必须通过这条成功之路,当然要在专业人士的帮助下。
另外,我有一个包含 2 个应用程序、配置文件和帖子的网站在这个项目中,我可以在模板 (posts/main.html) 的列表中看到我关注的人,问题是我也需要相同的列表另一个模板(profiles/main.html)。
我已经复制了一段代码,但它不起作用。我真的不知道如何更好地解释它,或者我不知道如何准确搜索它。 我试过这个: 1.) 如何在不同的应用模板中使用视图 2.) 如何从其他应用视图导入视图 3.) 还有更多,我阅读了所有的东西,但找不到我要找的东西
非常感谢您的帮助。
发帖应用
posts/models.py
class Post(models.Model):
...
author = models.ForeignKey(Profile, on_delete=models.CASCADE)
text = models.TextField(default='no text...')
...
def __str__(self):
return str(self.text)[:30]
posts/urls.py
from django.urls import path
from .views import posts_of_following_profiles, index, contact, about, category, PostListView, PostDetailView, post, detay
from profiles.views import ProfileListView
app_name="posts"
urlpatterns = [
...
path('following/', ProfileListView.as_view(), name='posts-follow-view'),
...
]
posts/views.py
def posts_of_following_profiles(request):
# get logged in user profile
profile = Profile.objects.get(user=request.user)
# check who we are following
users = [user for user in profile.following.all()]
# initial values for variables
posts = []
qs = None
# get the posts of people who we are following
for u in users:
p = Profile.objects.get(user=u)
p_posts = p.post_set.all()
posts.append(p_posts)
# our posts
my_posts = profile.profile_posts()
posts.append(my_posts)
# sort and chain qs and unpack the post list
if len(posts)>0:
qs = sorted(chain(*posts), reverse=True, key=lambda obj: obj.ilan_tarihi)
return render(request, 'posts/main.html', {'profile':profile, 'posts':qs})
posts/main.html
这部分运行良好
<h3>list of followings</h3>
{% for p in profiles.following.all %}
<br>{{p}} <br>
{% endfor %}
个人资料应用
profiles/models.py
class Profile(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
following = models.ManyToManyField(User, related_name='following', blank=True)
text = models.TextField(default='no text...')
def profile_posts(self):
return self.post_set.all()
def __str__(self):
return str(self.user.username)
profiles/urls.py
from django.urls import path
from .views import ProfileListView, ProfileDetailView, follow_unfollow_profile
from posts.views import posts_of_following_profiles
app_name = 'profiles'
urlpatterns = [
path('switch_follow/', follow_unfollow_profile, name='follow-unfollow-view'),
path('portfolio/', posts_of_following_profiles, name='profile-list-view'),
path('<pk>/', ProfileDetailView.as_view(), name='profile-detail-view'),
]
profiles/views.py
def follow_unfollow_profile(request):
if request.method=="POST":
my_profile = Profile.objects.get(user=request.user)
#profile_pk is the name of the input in detail.html
pk = request.POST.get('profile_pk')
obj = Profile.objects.get(pk=pk)
if obj.user in my_profile.following.all():
my_profile.following.remove(obj.user)
else:
my_profile.following.add(obj.user)
return redirect(request.META.get('HTTP_REFERER'))
return redirect('profiles:profile-list-view')
profiles/main.html
这就是我想要的,这个代码不起作用(它与 posts/main.html 中的代码相同)
<h3>list of followings</h3>
{% for p in profiles.following.all %}
<br>{{p}} <br>
{% endfor %}
