IntegrityError: duplicate key value violates unique constraint in Model.objects.create(...)
I'm not sure what is happening but create method started raising IntegrityError: duplicate key value violates unique constraint "clients_client_pkey" When trying to create a Client. I'm not putting id nor pk attribute to the create method. I've recently loaded some fixtures from CSV, there were clients with their id values so maybe it has some causality. Client.name was unique but I made it not unique and migrated the DB. snippet IntegrityError: duplicate key value violates unique constraint "clients_client_pkey" DETAIL: Key (id)=(25) already exists. The above exception was the direct cause of the following exception: IntegrityError Traceback (most recent call last) ~/PycharmProjects/project2/project2/apps/internals/stats/fixtures/stats.py in <module> ----> 1 load_realestates(delete_old=True) ~/PycharmProjects/project2/project2/fixtures/alex1_csv_loader.py in load_realestates(delete_old) 43 c = Client.objects.get(name=line['majitel_meno'],broker_id=line['makler']) 44 except: ---> 45 c = Client.objects.create(name=line['majitel_meno'],broker_id=line['makler']) Where can be the thing? -
Django - Unique upload filenames regardless of file extension
I want to create unique filenames for each uploaded file (Similar to this), but regardless of the extension (ie, name.txt and name.dxf is a clash) I'm converting files on my server (ie, ogg, wav, etc) to a particular filetype extension, ie. mp3, and then removing the original file. This issue is if someone uploads a file with different extension but the same base name, then the conversion will override the original file. I can obviously do a check if the target file already exists. I know Django will also generate some sort of unique identifier (appended to the uploaded filename) such as "_HVk3AIt" if there is a conflict with an exact filename match. Is this a UUID? I originally though adding a randomly generated UUID would be a bad solution because even though 2^128 is like 4*10^38 (little chance of clash) you could technically override something eventually, but I guess you just keep checking the new proposed filename, and add secondary UUID if you've got a second collision etc. Is this a good solution, or what is standard practise for such a problem? -

django filter not working with date range

Here's my Code: class CustomQuerySetManager(models.Manager): """A re-usable Manager to access a custom QuerySet""" def __getattr__(self, attr, *args): print(attr) try: return getattr(self.__class__, attr, *args) except AttributeError: # don't delegate internal methods to the queryset if attr.startswith('__') and attr.endswith('__'): raise return getattr(self.get_query_set(), attr, *args) def get_query_set(self): return self.model.QuerySet(self.model, using=self._db) class SampleModel(models.Model): objects = CustomQuerySetManager() class QuerySet(models.QuerySet): def test(self): print("test function was callsed") With this these happens: SampleModel.objects.test() # This works SampleModel.objects.all().test() # This doesnt works... Why does this happen? -
Whats the right way to get the current user logging in using angular and django-rest-framework?
Im using Angular as frontend and Django as backend. When fetching the logged in user, there is a small lag or "flickering" in the username displayed in the top menu due to the Angular having to ask the backend for the user data, after receiving the token and wait for the promise to return the user data. To authenticate and log in i use django rest framework: url(r'^token-auth/', obtain_auth_token) This returns a Token - all works well and Im logged in. But this call doesnt return any user data, so to solve this I created a separate api view that returns the user. A service in Angular is triggered to fetch the user data directly after receiving the token. But to do that Angular has to call the user view separately and that in turn can lead to "lag" in the way that the users data wont load instantly in the menu upon login (because Angular has to fetch the users data again, after receiving the users token on the first call). This got me thinking, what is the best way to get the logged in user data after receiving the Token and "beeing logged in"? Is there a better … -
On click (image/button) store data in ... to render another html template live
I would like to retrieve the img.id or img.alt data when an image is clicked in my (x.html) template. The retrieved data will then be used to fill another template (dashboard.html). My only question is how to retrieve the data on an 'onclick' event. Once i have the data stored somewhere, I will be able to figure out how to fill another template based on that information. And does your answer change if i would add that the 'dashboard.html' should be a live stat dashboard. I already have my js.js active, but i cannot find the correct function for it and the appropriate reference in the html. I tried several javascript/ajax solutions, but since i am not that skilled in js I was unable to get the function/javascript working on my page.

Why is ORM filter acting different in shell and server (both in production and development)
Using Django 2.2 and Postgres database. I'm supposed to show a product page, where someone chooses product attributes and then the view fetches the product variant based on the attributes. When I run a double filter based on two ManytoMany attributes in shell it works fine and returns the single product variant, but when it is run by the view the second filter is ignored and it returns multiple. I've tried this on both my machine (manage.py runserver / shell) and in the production environment (gunicorn vs shell). I've tried to filter by multiple methods, and second filter is always ignored. models.py relevant data class VariantType(models.Model): name = models.CharField(max_length=200, db_index=True) class VariantValue(models.Model): name = models.CharField(max_length=200, db_index=True) var_type = models.ForeignKey(VariantType, related_name='value', on_delete=models.PROTECT) class Product(models.Model): (info fields for product) class VariantProduct(models.Model): master = models.ForeignKey(Product, related_name='variants', on_delete=models.PROTECT) variant = models.ManyToManyField(VariantValue, related_name='products') (info fields for VariantProduct) views.py @require_POST def var_manage(request, product_id): data = request.POST sizevar = VariantValue.objects.get(id=data.get('size')[0]) colorvar = VariantValue.objects.get(id=data.get('colour')[0]) product = get_object_or_404(Product, id=product_id) var_product = product.variants.filter(master=product, variant=sizevar).filter(variant=colorvar) (further action with var_product) manage.py shell #set POST data manuall data = {'csrfmiddlewaretoken': ['...'], 'size': ['18'], 'colour': ['13'], 'items': ['1']}; sizevar = VariantValue.objects.get(id=data.get('size')[0]); colorvar = VariantValue.objects.get(id=data.get('colour')[0]); product = get_object_or_404(Product, id=product_id); var_product = product.variants.filter(master=product, variant=sizevar).filter(variant=colorvar); if I … -

Django: how to over ride CheckboxSelectMultiple
I am using Materialize CSS and Django. However Django displays checkboxes in a way Materialize does not understand, so they do not render. How an I override CheckboxSelectMultiple to make it render correctly? I found a question similar to my one but using Bootstrap: Overriding django's CheckboxSelectMultiple widget for Awesome Bootstrap Checkboxes Perhaps something similar can be implemented for Django? Django displays like this: <label for="id_day_2"> <input type="checkbox" name="day" value="Tue" id="id_day_2">Tue</label> But Materialize CSS expects it like this: <input type="checkbox" id="id_day_2" name="day" value="Tue" /> <label for="id_day_2">Name</label> So how can I over ride the widget in order to get Django to display the code the way Materialize wants it? -

But I also want to show the list of deals for a specific tag. deal/serializers.py from rest_framework import serializers from . models import Deal from . . tag.serializers import TagSerializer class DealsSerializer(serializers.HyperlinkedModelSerializer): tags = TagSerializer(many=True, read_only=True, source='tag_set') class Meta: model = Deal fields = ('url', 'id', 'title', 'link', 'tags') tags/serializers.py from rest_framework import serializers from . models import Tag from . . . api.deal.serializers import DealsSerializer class TagSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = Tag fields = ('url', 'id', 'name') class TagAllSerializer(serializers.HyperlinkedModelSerializer): dea_tags = DealsSerializer(many=True, read_only=True) class Meta: model = Tag fields = ('url', 'id', 'name', 'dea_tags') deal/models.py tag_set = models.ManyToManyField(Tag, related_name='dea_tags') I missed a step because I have an error ImportError: can not import name 'DealsSerializer' -
Face Detection with Flask and Dlib
I want to create a UI for my face recognition code. I am using flask to connect HTML pages to python code. I have one simple machine learning model which will give output. I want to stream camera on the HTML page and display the output there. The following code streams a camera on html page, but after streaming I am not able to connect it to python face recognition code. My python code is in detector function. #Flask code @app.route('/detector1') def detector1(): return render_template('detect_face.html') @app.route('/video_viewer2') def video_viewer2(): return Response(detector(),mimetype='multipart/x-mixed-replace; boundary=frame') I want to show live web camera on HTML page and after clicking button it should give me value predicted by my machine learning model. -
How to change default behavior of serializers
I am doing some stuff with the django restframework. Very basic now, but I like to have my data coming back to me bit differently. This is how I get the response now: [ { "line": "line1", "user_text": "Some text", "topic": "value/xrp" }, { "line": "line2", "user_text": "Some text 2", "topic": "beer/heineken/sale" } ] This is what I like to get: { "line1": { "user_text": "Some text", "topic": "value/xrp" }, "line2": { "user_text": "Some text 2", "topic": "beer/heineken/sale" } } This is my serializer: class LineSerializer(serializers.Serializer): line = serializers.CharField(max_length=16) user_text = serializers.CharField(max_length=16) topic = serializers.CharField() And the model (as reference) class Line(models.Model): display = models.ForeignKey(Display, on_delete=models.CASCADE, related_name='lines') line = models.CharField(max_length=16) user_text = models.CharField(max_length=16, null=True, blank=True) topic = models.ForeignKey(Topic, on_delete=models.CASCADE, blank=True, null=True) def __str__(self): return self.line I looked in the rest framework documentation and a bit here on stackoverflow but I could not find an answer yet. If someone has hints for me that would be very much appreciated :) -
Django admin increases response times
I recently added an app to my Django web application. I am baffled at an issue that is occurring. When I add the below admin.py file to the app and deploy the code, response times increase in multiple areas of the site, with many areas unrelated. Is there something wrong about the way the ModelAdmin is written? Has anybody experienced this before? I am running Django 1.11. admin.py: class SubscriberAdmin(admin.ModelAdmin): list_display = ('email',) fields = ('email', 'verified') readonly_fields = ('email', 'verified') list_per_page = 50 admin.site.register(Subscriber, SubscriberAdmin) models.py: class Subscriber(models.Model): email = models.EmailField(null=False, unique=True) activation_key = models.CharField(max_length=64) key_expires = models.DateTimeField(default=get_key_expiration) verified = models.BooleanField(default=False) agency_class = {} agency_type = None @classmethod def send_notifications(cls, agency_type, slugs): """ Sends notification emails to all subscribers. :param agency_type: 'salary' or 'pension' :param slugs: [list of agency slugs] """ cls._set_agency_type(agency_type) subscribers = cls.objects.all() for subscriber in subscribers: subscriber._send_notification(slugs) def _send_notification(self, slugs): # code removed for brevity -
Django: get_context_date is not called in ListView
I have django 2.0 app using class based views. I have overrided the get_context_data to add custom contexts. but is does not work properly. class CollectorListView(LoginRequiredMixin, UserPassesTestMixin, ListView): login_url = '/account/login/' model = Collector template_name = "collectors_list.html" print('this_class_is_called') def test_func(self): try: return self.request.user.giver except Giver.DoesNotExist: return False def get_context_data(self, **kwargs): context = super(CollectorListView ,self).get_context_data(**kwargs) print('context_data_is_running') context['stars'] = 'STARS' return context However, the listview works, it does not call the overriden get_context_data method. in the console I get 'this_class_is_called' message printed, but I don't get the 'context_data_is_running'. -
Uploading multiple profile pictures saving only the last one Django
Initially, this worked fine only uploading one photo, but I have expanded it to three. Each of the 3 photos is clickable, triggering onclick="_upload()" and when the page is saved, the photos should display in their respective places (image, image_two and image_three). But when the page is saved, the last photo that was chosen displays in the image_three slot. Even if I choose a photo by clicking on image (the first image) it displays and saves to image_three, leaving the other two images as default photos. I can obviously go into the backend and manually add the photos, and then they display in their correct spaces client side, however that's not helpful. Am I missing something? Another question hinted at needing an Image class as ForeignKey to Profile but why is that necessary? update image form <form method="POST" enctype="multipart/form-data"> {% csrf_token %} <!-- clickeable first image to upload new photo --> <input type="file" name='image' accept="image/*" class="clearablefileinput" id="id_image" style="display:none"> <a href="#"> <img class="img-thumbnail account-img" src="{{ user.profile.image.url }}" width="240" class="img-fluid mx-auto d-block" onclick="_upload()"> </a> <!-- clickeable second image to upload new photo --> <input type="file" name='image_two' accept="image/*" class="clearablefileinput" id="id_image_two" style="display:none"> <a href="#"> <img class="img-thumbnail account-img" src="{{ user.profile.image_two.url }}" width="120" class="img-fluid mx-auto d-block" …
