Django. What is wrong ith this regex
I have a form for which the relevant model is keyed on a UUID models.py class FoodDiaryItem(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) ... urls.py urlpatterns = [ url(r'food-diary-entry/', views.food_diary_entry, name='food-diary-entry'), url(r'food-diary-entry/(?P<id>[0-9A-Fa-f-]+)', views.food_diary_entry, name='food-diary-entry'), ... views.py def food_diary_entry(request, id=None): print('food_diary_entry') if id: food_diary_item, created = FoodDiaryItem.objects.get_or_create(id=id) else: food_diary_item = FoodDiaryItem() ... As it stands, this code runs and the calls the function food_diary_entry in views.py However, if I comment out the first line of the urlpatterns list, it will not enter "views.py* suggesting it does not match the UUID portion of the regex. What is wrong here? -

Adding an item to many to many after creation in django
Recently I've been trying to do something with this. Think of the family as a facebook group. class Family(models.Model): name = models.CharField(max_length=50) owner = models.ForeignKey(User, on_delete=models.CASCADE, related_name='owned_families') users = models.ManyToManyField(User, related_name='families', blank=True) let's assume we have this a family object called fm, for illustration purpose. My problem is, The owner is one of the users right? I mean, When someone creates a family, He's now the owner right? he owns it but he's still a user listed in it's users list. Now, when I create a new family fm , I want to add the fm.owner to fm.users. Let's talk about what I've tried. post_save signal doesn't work with m2m. X m2m_changed happens when the field is changed, not created. X Overriding save method, lemme illustrate what I tried to acheive. ? def save(self, *args, **kwargs): old = self.pk super(Family, self).save(*args, **kwargs) if old is None: print('This actually shows up') self.users.add(self.owner) Basically, this saves the pk each time, First time a family is created, Before calling super..... it has no .pk so I'm counting on this to check if it had no pk (On creation). The problem is self.users.add(self.owner) doesn't work. I've tried to clone the object as whole and … -

How to change default admin search from Pages - Wagtail
By default wagtail admin searches Pages. I would like to change the default search. I believe I need to use the 'current' param in wagtailadmin_tags, but I am unsure how to do this. The wagtail docs state on https://docs.wagtail.io/en/v2.8/reference/hooks.html#construct-main-menu: A template tag, search_other is provided by the wagtailadmin_tags template module. This tag takes a single, optional parameter, current, which allows you to specify the name of the search option currently active. If the parameter is not given, the hook defaults to a reverse lookup of the page’s URL for comparison against the url parameter. However I am stuck with how to get started on this. -

Is this a correct class-based-django-view?
In my project i have a page that displays a form where the User inputs some irrelevant(for the moment project name) and a host/ip-address. When he hits the scan button he makes a post request. In the current moment i get that ip address and im trying to 'banner-grab' the running services on that ip/host and render the results to the page. In the code below i got that working but as im litteraly using django for the first time i think that my aproach is really bad cause all of my code( for grabbing the banner etc ) is in the POST function in my class-based-view.So question is can i do this in a better way? Maybe write that bannerGrab() function somewere else and, if form is valid just call the function in the POST method... class NewProject(View): # Reusable across functions form_class = ProjectData template_name = 'projectRelated/create_project.html' ports = [20, 21, 22, 23, 80, 3306] def get(self, request): # redundant to use it like this # form = ProjectData() form = self.form_class context = { 'form': form # this is a context variable that i can use in my html page. like this <h3> {{ context.var }} </h3> … -

Django User profile model form edit for current user
I have searched a lot on this and all the questions and answers provided are never clear and fit for purpose, maybe I'm going at it the wrong way. I have just recently started Python and Django, so know very little about it. I am creating a website and have done the basic authentication using Django and even added the facebook authentication using social-django. That part all works fine. Now I am moving to profile information and how to update it after you sign up to website. I have the below UserProfile in models.py: class UserProfile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) first_name = models.TextField() last_name = models.TextField() email_address = models.EmailField() phone_number = models.TextField() In forms.py a testing form: class UserProfileForm(forms.ModelForm): class Meta: model = UserProfile fields = ['first_name','last_name','email_address'] Then in views.py I have a function: def myprofile(request): if request.method == 'POST': form = UserProfileForm(request.POST, instance=request.user) if form.is_valid(): form.save() user_profile = UserProfile.objects.get(user=request.user) if request.method == 'GET': user_profile = UserProfile.objects.get(user=request.user) form = UserProfileForm(instance=user_profile) return render(request, 'pandp/myprofile.html', {'user_profile' : user_profile, 'form' : form}) And finally myprofile.html: <div class="profile-details"> <form method="post">{% csrf_token %} {{ form.as_p }} <input type="submit" value="Update"> </form> </div> I was struggling from the start to actually only load UserProfile of the logged … -
