Differences between using Resource Model (Tastypie) and single Rest-Framework function
First of all, I am new to Python and Django, I am trying to understand the pros/cons of apis by single function and apis by resources (Tastypie's ModelResources). I had been working on a Django project and been using rest-framework along all the way. However, I created each function for each api from the server. For example, this is a simple register function I wrote using rest-framework: @api_view(['POST']) @permission_classes((AllowAny,)) @parser_classes((JSONParser,)) def register(request): if request.data is not None: try: username = request.data['username'] password = request.data['password'] user = User.objects.create_user (username=utils.encrypt(username), password=utils.encrypt(password)) ...... This is another register example using Tastypie's ModelResource: class RegisterUserResource(ModelResource): class Meta: allowed_methods = ['post'] always_return_data = True authentication = Authentication() authorization = Authorization() queryset = User.objects.all() resource_name = 'register' ....... def obj_create(self, bundle, **kwargs): try: username = bundle.data["username"] password = bundle.data["password"] if User.objects.filter(username=username): raise CustomBadRequest( code=status.HTTP_201_CREATED, message="This username is taken" ) # Create object bundle.obj = User.objects.create_user(username=username, password=password) bundle.obj.save() # Create user profile object UserInfo.objects.create(user=bundle.obj) except KeyError: raise CustomBadRequest( code="missing_key", message="Must provide {missing_key} when creating a user." ) except User.DoesNotExist: pass return bundle Please help me to understand what are the differences between those two ways and which way is better. I personally think using Tastypie's ModelResource is pretty … -
Django REST framework serializer without a model
I'm working on a couple endpoints which aggregate data. One of the endpoints will for example return an array of objects, each object corresponding with a day, and it'll have the number of comments, likes and photos that specific user posted. This object has a predefined/set schema, but we do not store it in the database, so it doesn't have a model. Is there a way I can still use Django serializers for these objects without having a model? -
Why does there not exist a i18n_patterns variation for countries for Django?
We use i18n_patterns to add language codes to urls and to help us serve different content based on the language required by the client. But we can also wish to have country specific content. For example: 127.0.0.1:8000/en --> should serve content specific to the United States 127.0.0.1:8000/ca/fr --> should serve content specific to canada and french Is there another way that Django wants us to handle delivering country specific content, and if there isn't, why doesnt there exist libraries and more demand for the type of library I am asking about. PS: I found a github library that does this, but it seems to be outdated with the newer versions of Django Github Link -
AWS lambda could not connect to EC2 Mysql Server
I have been trying to connect EC2 mysql server from AWS Lambda which is not happening. I find Lambda function is perfectly working when I just comment database fetching code. I am using Django framework and using zappa to deploy code to Lambda and add setting in AWS API GateWay. Things I did: Created a user in Mysql with the aws Lambda host address While deploying with zappa Added Subnet Id and Security Group Id in settings file. Did not create new VPC as the EC2 instance has default VPC created. So I just used it. I see it Lambda function is working really fine when I just comment Database code(EC2 Mysql database, trying to fetch results from aws lambda). Code: class GetData(APIView): def post(self, request, format=None): if request.method == "POST": item_id = request.data.get('item_id') if item_id not in [None, '', ' ']: item = Item.objects.get(item_id=item_id) # Comment 1 item_name = item.item_name # Comment 2 return Response({"return": "OK OK OK OK"}) else: return Response({"return": "ITEM NOT OK "}) else: return Response({"return": "NOT OK "}) In the above code If I just comment out comment 1 and comment 2 lines I am receiving status code 200 and returning below response {"return": "OK … -

Getting KeyError when attempting to get a value for field <field> on serializer <serializer> in Django Rest Faramework
I'm getting an error when trying to access serializer.data before returning it in the Response(serializer.data, status=something): Getting KeyError when attempting to get a value for field <field> on serializer <serializer> Because of the OrderedDict, I can change the order in which the fields are declared and I'll get a different <field> in the KeyError.

What is the best practice of integrating Django with Vuejs?
There is not enough information about that topic. I want to make some part of UI using Vuejs, not 100% Vuejs+Django rest framework. The question is, how to integrate in the right and efficient way? What if I put the Vuejs scripts only to templates where I will use it. (Example: login.html, where it will validate my login form)? Using Webpack. If I gonna use the Webpack, npm packages, how to integrate it with Django, I guess if I create a folder with packages in my "static" folder it will be a disaster. Can anyone advise something, or maybe do you know a good tutorial? -
Unable to enforce authentication requirement in Django Rest Framework
I'm trying to enforce Authentication for access to my API, but the permission_classes = permissions.IsAuthenticated,) attribute of my ViewSet doesn't seem to be working. Because I try to access the User's profile later on when in get_queryset(), I'm getting errors like: TypeError: 'AnonymousUser' object is not iterable" I also have authentication set in my rest_framework settings: 'DEFAULT_PERMISSION_CLASSES': ('rest_framework.permissions.IsAuthenticated',), And I also added to my dispatch method before doing the other business logic checks on the User profile: def dispatch(self, request, *args, **kwargs): if not request.user.is_authenticated: return Response(status=status.HTTP_401_UNAUTHORIZED) That's not working either: File "/lib/python3.5/site-packages/rest_framework/response.py", line 57, in rendered_content assert renderer, ".accepted_renderer not set on Response" AssertionError: .accepted_renderer not set on Response Why do none of these authentication controls work? -
Django DateTimeField hide date
I have a model where an object is called time which is model.DateTimeField(default=datetime.now) I also have a form where the user can specify the time, but I wanted to only have the H: M in there, not the whole datetime. I tried using the TimeInput widget in my form, but that would give me an error upon submitting because I didn't have the 'date' portion of the DateTimeField. If I use models.TimeField for time, I lose the ability to keep track of the date in the admin page. How can I hide the date from showing in my form? -
invalid literal for int() with base 10: 'explore', but I'm not using numbers. Only returning a list of shows. Any Ideas?
I'm pretty new to Django, and I'm having a hard time figuring out this error code.

Best practices for products catalogue in Django
I'm working on a catalogue application for storing product information in Django. The challenge here is that there are a lot of products in the catalogue, each with their own attributes. Since this is a key part of the application, and a lot will be built around it, I want this to be designed as good as possible. I know there are several options of handling this in Django, but I would like to know what others have experienced with these several options. The first option: Single abstract class I could just create a single abstract class, which contains all the base attributes, and let other classes derive from that one class. class Product(models.Model): name = models.CharField(max_length=100) description = models.TextField(max_length=1000) price = models.DecimalField() class Meta: abstract = True class Phone(Product): series = models.CharField(max_length=100) This would be the most straightforward option, but this will include a lot of work in Django Forms and Views. This will also create a single table for each Product subclass, so when the Product class is changed, all other tables will have to changed as well. The second option: Product base class Here the Product class is not abstract, which implies this class can be used … -
How to render a form in Django in a template hierarchy
my base_page.html is this {% load static %} <!DOCTYPE html> <html lang="it"> <head> <meta charset="UTF-8"> <!-- Bootstrap and other things --> {% block head %}Additional head info{% endblock %} <title>Title</title> </head> <body> {% include "planner/navbar.html" %} {% block content %}Page content{% endblock %} <footer> <div class="navbar navbar-default navbar-fixed-bottom"> <span class="navbar-text pull-left">Credits</span> </div> </footer> </body> </html> which includes a navbar template {% load static %} <nav class="navbar navbar-default"> <!-- <div class="row"> --> <div class="col-lg-2 logo-container"> <img class="logo" src="{% static "planner/img/logo.svg" %}"/> </div> <div class="spacer col-lg-5 "></div> {% include 'planner/login_form.html' %} </nav> And then I have a homepage.html which extends base_page.html, of course. As you can see, the navbar is in turn including a login_form.html for a form I specified in forms.py, constisting of a CharField for email and a PasswordField. This is the form template: <form id="login_form" class="login-form col-lg-5 nav-links" action="{% url 'planner:login' %}" method="post"> <div class="col-lg-5 nav-links"> <div class="input-group"> {{ form.email }} <i class="glyphicon glyphicon-user form-control-feedback "></i> </div> </div> <div class="col-lg-5 nav-links"> <div class="input-group"> {{ form.password }} <i class="glyphicon glyphicon-lock form-control-feedback"></i> </div> <input type="submit" value="Login"> </div> </form> Now, how can I pass that form variable in the template hierarchy?

Here is my code. fake = Faker('uk_UA') class UserFactory(DjangoModelFactory): class Meta: model = User username = fake.user_name first_name = fake.first_name_male last_name = fake.last_name_male email = fake.safe_email But when I try to use it I got error: DataError Traceback (most recent call last) /Users/mero/.virtualenvs/fine-hut/lib/python3.6/site-packages/django/db/backends/utils.py in execute(self, sql, params) 63 else: ---> 64 return self.cursor.execute(sql, params) 65 DataError: value too long for type character varying(30) I assume that problem is in too long fields generated by Faker. But I didn't find any way to restrict it's length in python, though found few answers for Ruby Faker. Is there way to do this in python Faker? Or maybe there is some other way to use Faker for generate locale-specific fields? -
Django and Premade mysql databases
I have two database in mysql that have tables built from another program I have wrote to get data, etc. However I would like to use django and having trouble understanding the model/view after going through the tutorial and countless hours of googling. My problem is I just want to access the data and displaying the data. I tried to create routers and done inspectdb to create models. Only to get 1146 (table doesn't exist issues). I have a unique key.. Lets say (a, b) and have 6 other columns in the table. I just need to access those 6 columns row by row. I'm getting so many issues. If you need more details please let me know. Thank you.
