Django display remote api response (in json) without storing to backend database
How can I implement a super lightweight frontend data display on Django which: the frontend page just need to display json which is response from a remote http request I don't want to store the reponse on Django database , as the user is just checking remote data, the data changes frequently , it is meaningless for me to keep a local copy(my website just provide a frontend interface for the use to check data per their interest: input an ID , retrieve remote data) Is there a lightweight implementation in Django that can do a super lightweight json data display ? Here is what I am doing : I have parsed http response with jq, extract data fields website users are interested I want to find a way to display data in Django in a super lightweight tech implementation, as long as the data is display on Django webpage and show it to the users. We are good. -
Django AuthenticationForm not working, the form takes the data but nothing happens
So basically I'm trying to do a simple login system using Django AuthenticationForm and LoginView. The form takes the user input and when the login button is pressed, the page just reloads, instead of throwing validation errors or logging the user and redirecting him. I've tried to overwrite the clean method but the result is the same. I don't know what I'm doing wrong. Аny help will be appreciated, thanks in advance! This is the User model: class StoreUser(auth_models.AbstractBaseUser, auth_models.PermissionsMixin): email = models.EmailField( unique=True, ) date_joined = models.DateTimeField( auto_now_add=True, ) is_staff = models.BooleanField( default=False, ) USERNAME_FIELD = 'email' objects = StoreUserManager() Here is the Login view: class UserLoginView(auth_views.LoginView): form_class = UserLoginForm template_name = 'store_auth/user_login.html' success_url = reverse_lazy('homepage') And also the form: class UserLoginForm(auth_forms.AuthenticationForm): email = forms.EmailField(widget=forms.EmailInput(attrs={'class': 'form-control', 'id': "email-login", 'placeholder': "Enter your email",})) password = forms.CharField(widget=forms.PasswordInput(attrs={'class': 'form-control', 'id':"password-login", 'labels': "Password", 'placeholder': "Enter your password", })) And the HTML: <form method="post" action="{% url 'user login' %}"> {% csrf_token %} <div class="form-group"> <label for="email-login">E-Mail</label> {{ form.email }} </div> <div class="form-group"> <label for="password-login">Password</label> {{ form.password }} </div> <a href="javascript:;">Forgotten Password?</a> <div class="padding-top-20"> <button class="btn btn-primary" type="submit">Login</button> </div> -
Order queryset by field in intermediary table with recursive m2m relationship
I have followers/followees system in my django app and I want to order by user's followers and followees by action time when appropriate action is happend. My models: class UserFollow(models.Model): followee = models.ForeignKey('CustomUser', on_delete=models.CASCADE, related_name='follower_set') # The one who is followed follower = models.ForeignKey('CustomUser', on_delete=models.CASCADE, related_name='followee_set') # The one who followed timestamp = models.DateTimeField(auto_now_add=True) class CustomUser(AbstractBaseUser, PermissionsMixin): # Other fields which don't matter in this question followers = models.ManyToManyField('self', blank=True, related_name='followees', symmetrical=False, through='UserFollow') For example i have user and i can get all his followers in reverse order when they followed this user: followers = user.followers.all() # returns <QuerySet [<CustomUser: follower1>, <CustomUser: follower2>, ... , <CustomUser: follower{n}>] The following qs of course doesn't work: followers = user.followers.order_by('-userfollow__timestamp') I can get followers pk in right order and then get followers objects: followers_pk = user.follower_set.values_list('follower', flat=True).order_by('-timestamp') # returns <QuerySet [n, ... , 3, 2, 1]> followers = CustomUser.objects.filter(pk__in=followers_pk) # returns <QuerySet [<CustomUser: follower1>, <CustomUser: follower2>, ... , <CustomUser: follower{n}>]> (user objects in reverse order) Any suggestions or tips to achieve what i want? -

Django - after changing all reverse related objects the parent object still cannot be deleted
I have the following model for deomnstration purposes): class ProjectModule(models.Model): name = models.CharField(...) module = models.ForeignKey('ProjectModule', ....., on_delete=models.PROTECT) ... (many more fields and relations) ... I wrote a function to merge instances to get rid of duplicates and such. For this I need to change all related objects of the first object (succumber) and point them to their new parent (a submodule of the survivor). After changing all foreign keys I delete the succumber. new_parent = survivor.projectmodule_set.filter(name=entry.name).first() succumber.projectmodule_set.update(module=new_module) succumber.delete() But that's not working because Django throws the following error: "Cannot delete some instances of model 'ProjectModule' because they are referenced through a protected foreign key: 'ProjectModule.module'", <QuerySet [<ProjectModule: 1.1 : LCP : 5583>, <ProjectModule: 1.2 : JB1 : 5583>, <ProjectModule: 1.3 : JB2 : 5583>]> Now, I just changed these (reverse) related objects and gave them a new foreign key. Their name even reflects that (5583 is the id of the new parent). Reloading the succumber before deleting does not help either. It just can not "forget" these relation and therefore can not be deleted although the relations have already changed. I also tried the "long approach": for submodule in succumber.projectmodule_set.all(): submodule.module = new_parent submodule.save() But no luck. What am … -

Initializing a queryset for a dropdown field in a ModelForm
I have a problem with filtering a queryset through a list of object ID's. Upon form submission, the error [{'item': ['Select a valid choice. That choice is not one of the available choices.']}] shows up. When passing req (a list of integers) into a filtered queryset, Django does not accept req as a set of valid choices/objects and does not save the form. However, when passing a preset list that contains the same values as req, Django accepts and saves the form. I tried printing if req is equal to the same preset list and it returned True. views.py class TransferAddView(LoginRequiredMixin, generic.CreateView): ... def form_valid(self, form, **kwargs): ctx = self.get_context_data() inlines = ctx['inlines'] form.instance.requisition = ctx['req'] if inlines.is_valid() and form.is_valid(): tran = form.save() inlines.instance = tran inlines.save() return super(TransferAddView, self).form_valid(form) def get_context_data(self, **kwargs): ctx=super(TransferAddView,self).get_context_data(**kwargs) ctx['req'] = MaterialRequisition.objects.get(pk=self.kwargs['req']) req = list(MaterialRequisitionItems.objects.filter(requisition=ctx['req']).values_list('item', flat=True)) ctx['item'] = Item.objects.filter(item__in=req) if self.request.method == 'POST': ctx['form']=TransferModelForm(self.request.POST) ctx['inlines']=TransferInlineFormSet(self.request.POST) ctx['form'].fields['transferStatus'].initial = 0 else: ctx['form']=TransferModelForm() ctx['form'].fields['transferStatus'].initial = 0 ctx['inlines']=TransferInlineFormSet(form_kwargs={'req':ctx['req'].pk}) return ctx forms.py class TransferItemsModelForm(forms.ModelForm): ... def __init__(self, *args, **kwargs): req = kwargs.pop('req', None) super(TransferItemsModelForm, self).__init__(*args, **kwargs) ... req = list(MaterialRequisitionItems.objects.filter(requisition=req).values_list('item', flat=True)) self.fields['item'].queryset = Item.objects.filter(item__in=req) -
