Django is running on private ip instead of the public one, is it problematic?
I just configured basically a server and before installing gunicorn + nginx I wanted to try my django runserver. So, I have a public IP and a private one. My front (Simple index.html + react) is correctly deserving the public IP, but my django only pass by the private one when I start ./manage.py runserver 0.0.0.0:8080 When I try: ./manage.py runserver public.I.P:8080 I have this error: Error: That IP address can't be assigned to. Is that normal? -

Django Update Profile View - Only allow logged in users to edit their own accounts
I have a Django model that is a AbstractBaseUser, I have made an update form where users can update their profile information, however, I am unable to find a way to let logged in users edit their own profile.

FreeBSD. Django-shell permission denied
I am trying to debug some application using Python 2.7.9 and Django 1.10 on FreeBSD.

The problems starts when I try to execute the same script from second user, I get: File "/usr/local/lib/python2.7/shelve.py", line 223, in __init__ Shelf.__init__(self, anydbm.open(filename, flag), protocol, writeback) File "/usr/local/lib/python2.7/anydbm.py", line 85, in open return mod.open(file, flag, mode) error: (13, 'Permission denied') I set all directories in usr/local to has - chmod 777. First and second users are in the same groups and from my point of view has the same permissions. I will be thankful for any hints or help, I am stuck with any ideas. Thank you in advance. -

How do I retrieve the values of selected checkboxes and show it in the template?
What am I doing ? I'm training on a simple application where one can order a pizza and select his toppings, once the form submitted it shows the submitted queries in the template file. What is the problem? I'm having a really hard time showing the checked checkboxes from the form on the template file. Here are my files : models.py class PickedDatas(models.Model): name = models.CharField(max_length=255, blank=True, null=True) class Picked(models.Model): name = models.CharField(max_length=255) picked = models.ManyToManyField(PickedDatas, blank=True) forms.py class CustomChoiceField(forms.ModelMultipleChoiceField): def label_from_instance(self, obj): return mark_safe('%s' % (obj.name)) class SomeForm(forms.ModelForm): class Meta: model = Picked fields = ['name', 'picked'] picked = CustomChoiceField(queryset=PickedDatas.objects.all(), widget=forms.CheckboxSelectMultiple()) views.py def some_view(request): if request.method == 'POST': form = SomeForm(request.POST) if form.is_valid(): ... else: form = SomeForm return render(request, 'features.html', {'form':form, 'picked':Picked.objects.all()}) As for the template file, I'm using the for loop to show Picked models datas. How can I achieve what I am trying to do ? -

Copy values from another field when create new field of the same model
I have django 1.10 project. There are I have a model Feedback: class Feedback(FirstMixin, SecondMixin, models.Model): company = models.OneToOneField( verbose_name='Company', to=Company, related_name='feedback' ) This model exists and DB table's column Company is filled by keys to Company's items.

Using a 'mapping dictionary' to save entries in model with django
i would like to pull info from different APIs that contains basically the same information and gather them in a generic model. How could I create a mapping to make the relations easier?

ranking a query based on string match
I'm trying to build a query which will rank the models based on a given string in Django. For example, if the given string is "adc", then number one rank would be any model that contains this exact string in their chosen field, second rank would be the one closest to the string "adc 1" etc.. Is there any available libraries/frameworks I can use to accomplish this task? If not, any direction as to how this could be accomplished would be helpful. -

I have problem with issue, with cache. I want to clear cache always when time is up. Below is part of my model in django 1.8 but app didn't used my method clear_cache_when_times_up. Is class model good place to clear cache when time is up? I want to clear cache on list and on detail page, because there I use time. class Article(BaseModel): title = models.CharField(max_length=255) short_text = models.TextField(max_length=10000, default='') livestream_url = models.URLField(default='', blank=True, null=True) livestream_from = models.DateTimeField('livestream from', blank=True, null=True) livestream_to = models.DateTimeField('livestream to', blank=True, null=True) def has_livestream(self): if self.livestream_from is None and self.livestream_to is None: return False return (self.livestream_from <= timezone.now()) and (self.livestream_to >= timezone.now()) def clear_cache_when_times_up(self): if self.has_livestream(): print('################## test #################') return cache.clear() -
Django query with ManyToMany relationship through
I am implementing the connect function like Linkedin. My models are class AFSUser(models.Model): connects = models.ManyToManyField("self", through='UserConnect', symmetrical=False) class UserConnect(models.Model): date_followed = models.DateTimeField(auto_now_add=True) date_approved = models.DateTimeField(null=True, blank=True) date_rejected = models.DateTimeField(null=True, blank=True) requester = models.ForeignKey(AFSUser, on_delete=models.CASCADE, related_name='request_user') acceptor = models.ForeignKey(AFSUser, on_delete=models.CASCADE, related_name='accept_user') I want to list connections of a user. I tried approved_connections = UserConnect.objects.filter(Q(requester=afsUser) | Q(acceptor=afsUser), date_aprroved__isnull=False, date_rejected__isnull=False) Then get the list from there. Any other way so i can do users = userA.connects.filter(...)
