How do i access the context data in the template?
context_object_name = 'item_list' template_name = 'krop_view.html' model = Item def get_queryset(self): user = self.request.user #gets current user object krop = get_object_or_404(Krop, owner=user) return Item.objects.filter(krop=krop) def get_context_data(self, **kwargs): context = super(KropListView, self).get_context_data(**kwargs) user = self.request.user context['krop'] = Krop.objects.filter(owner=user) return context A "Krop" is technically a shop with items, i can get all items for the shop owned by the current user. I want to also access data from the Krop model so I passed in the krop context data related to current user. How do I access this context data in the template? I've tried and looked up ways to get the specific variables like: {{ krop.owner }} {{ item_list.krop.owner }} ultimetley I want to access data from two different tables, but for one page. Please and thank you!!! -

Self-referencing foreign keys are listing everything if the value is null in Django-admin Page
I have a django model as below: class Words(models.Model): bare = models.CharField(max_length=100) accented = models.CharField(max_length=100) derived_from_word = models.ForeignKey('self', models.DO_NOTHING, blank=True, null=True, related_name='derived_words', related_query_name='derived_word') There is a field derived_from_word which shows that some of the words are derived from some other word. If it is not derived from any word so the field value is NULL. What issue i am having that when i register this model in the django-admin and when i opened any of the word for editing, the derived_from_word field is listing all the words and i can not find a way for it to list only the derived word or the NULL value. Due to high load of the words the drop down list is making the page unresponsive. -

Django 'extends' in html file from another app cover 'original' html file
I'm using base.html from another app, and in another app, it works perfectly. But in new app, I extends it, and I could load base.html with stylesheet, but the problem is they only load base.html file. I have no idea why it happens, and just guess maybe it's because of TemplateView and ListView, cuz I haven't used it before, so I can just guess that's the only reason. But I want to use it as well.

Django Rest Framework, overwrite _declared_fields attribute of serializer meta class
I am trying to decorate a serializer in order to add help text, like so: def help_decorator(*args, **kwargs): def inner(cls, sources=kwargs["sources"]): for k,v in sources.items(): cls._declared_fields[k].help_text = v return cls return inner help_text_source = {"foo": "help_foo", "bar": "help_bar"} @help_decorator(sources=help_text_source) class FoobarSerializer(serializers.Serializer): foo = serializers.CharField(max_length=10) bar = serializers.IntegerField() I've put a debugger into the function, and cls._declared_fields has been modified as expected. Then, the Serializer Meta class is instantiated to return a Serializer class: serializer = FoobarSerializer() Inspecting serializer.fields["name_of_fields"], shows that none of the fields have retained the help text. -
HTML Video tag not finding file
Using Django, trying to pull a video from a model. I appear to be pulling the correct file path but the video isn't being located. Have tried adding the full system directory from hard drive rather than just the context folder, hasn't worked out for me either. Have confirmed that video is in that location.

How to save custom fields with user data on Django?
I've created a "Account" class so i can get more columns on user information: class Account(AbstractUser): company_name = models.CharField(max_length=50) company_department = models.CharField(max_length=50) company_employees_quantity = models.IntegerField(default=1) def __str__(self): return self.username I've also created a form with this data so i can receive the information on my view. class AccountCreationForm(UserCreationForm): company_name = forms.CharField(max_length=50) company_department = forms.CharField(max_length=50) company_employees_quantity = forms.IntegerField() class Meta: model = Account fields = ('username', 'email') The problem is when the client send the data though the form, i receive all the fields but only the "core" user information is inserted on the database. class SignUpView(CreateView): form_class = AccountCreationForm success_url = reverse_lazy('login') template_name = 'signup.html' If o add a method form_valid on on view o can save the data field by field like this: class SignUpView(CreateView): form_class = AccountCreationForm success_url = reverse_lazy('login') template_name = 'signup.html' def form_valid(self, form): if form.is_valid(): account = form.save() account.company_name = form.cleaned_data["company_name"] account.company_department = form.cleaned_data["company_department"] account.company_employees_quantity = form.cleaned_data["company_employees_quantity"] account.save() return redirect(self.success_url) return super().form_invalid(form) But this look weird to me? the view/form/model shouldn't save my "custom" fields automatically along with the "core" user info? How do i do that? -

So what I'm trying to do is a dropdown list in a template, this list consists of the attribute of another object in another app, however, I don't seem to know what's going on in the HTML side, since it doesn't show any attributes, it shows nothing. I'm using class based templates and views Here's what I've done so far: project/models.py class Project(models.Model): projectID = models.AutoField(primary_key=True, db_column="Id", db_index=True, verbose_name='Project ID') description = models.CharField(max_length=900) def __str__(self): return str(self.projectID) def get_description(self): return str(self.description) this is the object that should show the dropdown list model pm/models.py: class Pm(models.Model): pmid = models.AutoField(primary_key=True, db_column="Id", db_index=True) pmnumber = models.CharField(max_length=50, unique=True, db_column="pmnumber") description = models.CharField(max_length=600) projectId = models.ForeignKey(Project, on_delete=models.CASCADE, db_column="ProjectID", related_name='+') def __str__(self): return str(f'{self.PMid}, {self.PMNumber}, {self.description}') this is the form pm/forms.py: class PMForm(forms.ModelForm): class Meta: model = Pm fields = ('pmnumber', 'description', 'projectId') and this is the views archive for that model: class CreatePMView(LoginRequiredMixin, CreateView): template_name = 'pm/new.html' form_class = PMForm success_url = reverse_lazy('project:feed') def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['user'] = self.request.user return context def get_description(self): return self.request.project.description And this is the part of the template where I want to render the description from the project and shows nothing: <select class="form-control"> {% for project in … -
Google Storage + JQuery-File-Upload + Django + Signed URL, how should I change submit() and relevant options?
I have the following js code and it uses the signed-url api to get signed urls for uploading content to google storage via Django api. When I use it with the following code : xhr.open("PUT", data.signed_url); xhr.setRequestHeader('Content-Type', file.type); xhr.send(file); It works fine and I am able to upload to Google Storage very large files. But obviously, when I do that, I cannot use any progress-bar features of jquery-file-upload. Can you please suggest on how I should alter the data.submit(), where shall I put it, and how should I change the options or settings prior to submitting. Should I be overriding add or submit callback ? I feel that there is a missing support for Google Storage with Jquery-file-upload as the only example covers only obsolute Google Blobstore in the following link : https://github.com/blueimp/jQuery-File-Upload/wiki/Google-App-Engine $("#fileupload").fileupload({ dataType: 'json', type: 'PUT', sequentialUploads: true, submit: function(e, data) { var $this = $(this); $.each(data.files, function(index, file) { // pack our data to get signature url var formData = new FormData(); formData.append('filename', file.name); formData.append('type', file.type); formData.append('size', file.size); // Step 3: get our signature URL $.ajax({ url: '/api/getsignedurl/', type: 'POST', processData: false, contentType: false, dataType: 'json', headers: { 'X-CSRFToken': Cookies.get('csrftoken'), }, primary_data: data, data: formData }).done(function (data) … -

Using materialize how do i center a tabs in nav-content
https://i.imgur.com/JBI7id0.png So basically i am having an issue. I have no problem in moving any of the tabs to the right or left side. But when i try to center all the tabs i'm having no luck. So in the image above i am trying to get DROP ME!, TEST 2, DISABLED TAB AND TEST 4 to be centered on the page. I am using the Extended Navbar with Tabs example on their website. <div class="nav-wrapper"> <a href="/" class="brand-logo" >Skolplattform</a> <a href="#" data-target="mobile-demo" class="sidenav-trigger"><i class="material-icons">X</i></a> <ul id="nav-mobile" class="right hide-on-med-and-down"> {% if user.is_authenticated %} <li><a href="/logout">Logout</a></li> <li><a>{{user.username}}</a></li> {% else %} <li><a class="waves-effect waves-light btn" href="/register">Register</a></li> <li><a class="waves-effect waves-light btn" href="/login">Login</a></li> {% endif %} </ul> </div> <div class="nav-content"> <ul class="tabs tabs-transparent"> <li class="tab"><a class='dropdown-trigger' href='#' data-target='dropdown1'>Drop Me!</a></li> <li class="tab"><a href="#test2">Test 2</a></li> <li class="tab"><a href="#test3">Disabled Tab</a></li> <li class="tab"><a href="#test4">Test 4</a></li> </ul> </div> </nav>``` -
Should I go for AbstractBaseUser or AbstractUser? - Django
I am building a web app with Django where different users can create posts, etc. At the moment I am using the default User model along with a Profile model I created. The default User model is sufficient enough, however, I would like the users to be able to only register with a username made up of integers and I would also like to add my own authentication for when registering a new username. Do you suggest I use the AbstractBaseUser model or the AbstractUser? What is the core differences between these and what would be better in my case? -
How do I adjust my Django serializer to accept an array of a field?
I'm using Django 2.0 and Python 3.7. I have the following models (CoopType is a many-to-many field of Coop) ... class CoopTypeManager(models.Manager): def get_by_natural_key(self, name): return self.get_or_create(name=name)[0] class CoopType(models.Model): name = models.CharField(max_length=200, null=False) objects = CoopTypeManager() class Meta: unique_together = ("name",) class CoopManager(models.Manager): # Look up by coop type def get_by_type(self, type): qset = Coop.objects.filter(type__name=type, enabled=True) return qset # Look up coops by a partial name (case insensitive) def find_by_name(self, partial_name): queryset = Coop.objects.filter(name__icontains=partial_name, enabled=True) print(queryset.query) return queryset # Meant to look up coops case-insensitively by part of a type def contains_type(self, types_arr): filter = Q( *[('type__name__icontains', type) for type in types_arr], _connector=Q.OR ) queryset = Coop.objects.filter(filter, enabled=True) return queryset class Coop(models.Model): objects = CoopManager() name = models.CharField(max_length=250, null=False) types = models.ManyToManyField(CoopType) #type = models.ForeignKey(CoopType, on_delete=None) address = AddressField(on_delete=models.CASCADE) enabled = models.BooleanField(default=True, null=False) phone = PhoneNumberField(null=True) email = models.EmailField(null=True) web_site = models.TextField() I don't know how to properly create a serializer to accept the inputs.

Django hide slug field to users in custom template
I've built a form with auto-generating slug field with short js code. I'd want to hide the slug field to user to prevent them being edited. //slugify.js const titleInput = document.querySelector('input[name=title'); const slugInput = document.querySelector('input[name=slug]'); const slugify = (val) => { return val.toString().toLowerCase().trim() .replace(/&/g, '-and-') // replacing & with '-and-' .replace(/[\s\W-]+/g, '-') //replcaing spaces, non-word chars and dashes with a single '-' }; titleInput.addEventListener('keyup', (e) => { slugInput.setAttribute('value', slugify(titleInput.value)); }); //models.py slug = models.SlugField(max_length=100, unique = True) as I remove it from forms.py, slugfield becomes blank. I know what the problem is, but I don't know how should I fix it. I've tried removing the slugfield from forms.py, but it would just does not add the slug, because I targeted the slug with the input in slugify.js. I've tried editable = False on slugField, but it would give me an error django.core.exceptions.FieldError: 'slug' cannot be specified for VideoPost model form as it is a non-editable field Would there be any other way that I could hide slugfield from the form and properly save the slug as well?
