Nginx 403 Forbidden on serving large images
I have setup a django application, in which user can upload his image and it is served by nginx and gunicorn. I have a problem with uploading large image files which does not get appropriate permissions to be served by nginx location /medias/images/ { root /var/www/html; } However the smaller images get their permissions fine and are served properly The point is that both uploading small and semi-large (3mb) image files are done by a same process. any ideas? Thanks -
Deploying a Django Cookiecutter project with Docker to Digital Ocean
My problem is that I'm not properly deploying my project, and I'm not exactly sure where I'm going wrong. In following Cookiecutter documentation to deploy my project with docker, I am getting the project to launch in my terminal. Here are the commands I'm running - docker-machine create -d digitalocean --digitalocean-access-token=..... prod eval $(docker-machine env prod) docker-compose -f production.yml build docker-compose -f production.yml up At this point, the project is running, I can hit it from the URL - everything is great. The problem is that if I CTRL+C out of the terminal, it kills the services. This makes me think I'm not deploying the image to my Digital Ocean droplet, and that I'm running the image locally. Is that correct? Happen to have any advice on how to fix this? -
Check on integration test if user has log in
I am trying to create a test for checking in the user has successfully log in or not. But I am having troubles to check once the user fulfills the log in form if it appears as authenticated or not.

Django Restframework _ custom authentication
I wrote some code for custom authentication with this structure: serializers.py class LoginSerializer(serializers.Serializer): first_token = serializers.CharField() phonenumber = serializers.CharField() token = serializers.CharField(max_length=255, read_only=True) views .py class LoginView(APIView): serializer_class = LoginSerializer permission_classes = (AllowAny,) def post(self, request, format=None): phonenumber = request.data.get('phonenumber', None) first_token = request.data.get('first_token', None) try: x = User.objects.get(phonenumber=phonenumber) except x.DoesNotExist: return Response('user does not exists') if first_token == x.first_token.token: user = authenticate(phonenumber=phonenumber) login_user = login(request, user) user_info = { 'phonenumber': user.phonenumber, 'username': user.username, 'token': user.token, 'is_admin':user.is_admin, } return Response(user_info, status=status.HTTP_200_OK) urls.py urlpatterns = [ re_path(r'^login/$', views.LoginView.as_view(), name='login'), ] so, authentication and login is successful and user logs in. but when i try to go another page testframework doesnt store the authentication. I made a custom authentication already . auth.py class PhoneAuthentication(authentication.BaseAuthentication): authentication_header_prefix = 'Token' def authenticate(self, request): request.user = None auth_header = authentication.get_authorization_header(request).split() auth_header_prefix = self.authentication_header_prefix.lower() if not auth_header: return None if len(auth_header) == 1: return None elif len(auth_header) > 2: return None prefix = auth_header[0].decode('utf-8') token = auth_header[1].decode('utf-8') if prefix.lower() != auth_header_prefix: return None return self._authenticate_credentials(request, token) def _authenticate_credentials(self, request, token): try: payload = jwt.decode(token, settings.SECRET_KEY) except: raise exceptions.AuthenticationFailed("invalid authentication . could not decode token") try: user = User.objects.get(pk=payload['id']) except User.DoesNotExist: raise exceptions.AuthenticationFailed('No such user') return(user, token) -
Using loaddata to add a ManyToOneRel into a django models class
I have an .xml file with country and continent data, which looks like this <object model="countrydata.continent" pk="7"> <field name="name" type="CharField">South America</field> <field name="code" type="CharField">sa</field> </object> <object model="countrydata.country" pk="1"> <field name="name" type="CharField">Andorra</field> <field name="capital" type="CharField">Andorra la Vella</field> <field name="code" type="CharField">ad</field> <field name="population" type="PositiveIntegerField">84000</field> <field name="area" type="PositiveIntegerField">468</field> <field name="continent" rel="ManyToOneRel" to="countrydata.continent">6</field> </object> The first object is to a continent, the second one is to a country. I'm trying to build models for them so that I can use manage.py loaddata command to parse through the .xml, but I'm having trouble with the ManyToOneRel -part. My models.py is from django.db import models class Continent(models.Model): name = models.CharField(max_length=60, default='') code = models.CharField(max_length=3, default='') class Country(models.Model): name = models.CharField(max_length=60, default='') code = models.CharField(max_length=3, default='') capital = models.CharField(max_length=60, default='') population = models.PositiveIntegerField(default=0) area = models.PositiveIntegerField(default=0) , but I'm not sure what I need to add to Country in order to be able to read the <field name="continent" rel="ManyToOneRel" to="countrydata.continent">6</field> line. I tried fiddling around with foreignkey and manytoonerel, but got neither of them working. Latest attempt example: continent = models.ForeignKey(Continent) and I get the error "Country has no field named 'continent'", so it leads me to believe that I'm establishing the model field in a wrong … -
Django: Superuser cannot login to admin and user page after making an email login field instead of username
I was looking for the the answer and I still can't find the solution, which works for me. I am new to Django. I write a web app, which will be basically a blog in which authors are going to have their sites and under each article there will be a comment section. I want that after creation a superuser will be automatically one of them. The username field is not necessary, because the authors will be recognized by their first and last names. That is why I need them to log in using just an email. The Django version that I use is 2.0 and I try to use CBV (Class-Based Views) as much as possible. After making the username irrelevant and using just email and password in the login page, I am unable to lo login in both cases: - as the user registered on the website in the website login page - as the admin registered through the console command createsuperuser on an admin login page Here is the practical example. After deleting the whole database and registering a regular user on the webpage and a superuser in the terminal, they are saved correctly in the database. … -

Django 2.0 Tutorial Pt 1 Error 404 - URL Conf Probelm?
I have been working through the Django 2.0 tutorial on their website. In part 1 it has me set up a separate polls app, and write some code into it. When I run the server after initially changing the code, I keep getting an error 404. I have followed the tutorial exactly and have even copy and pasted their code to no avail. I have a feeling that there is something they might have glossed over because they assume people might know it and I do not. I'm running Django 2.0 w/ Python 3.6 in an virtual environment.

Saving Instance with Foreign Key in Django
class B(models.model): # some fields class A(models.Model): b = models.ForeignKey(B) Now while in django serializer, I already have B created first. b = B.objects.get(id=1) Creating the instance for A like this: data['b'] = b But the serailizer.is_valid() gives error that it expected a dictionary but got that object.

Django Angular Folder structure to load angular templates
I've got the hang of constructing rest API's to pass all data, but I'm having trouble knowing how to set up the folder structure to be able to load an angular template by visiting an url. Lets say that in my settings.py I have a registered path api, that contains the JSON data i want to pass to the client, and have some angtemplate.html. I also have a Django app called apitest which gets data from the server and provides the data to the api that angular needs to get data from. How do I route the request so that when a user goes to a url on my server like 127.0.0.1:8000/apifetch, the user is presentet with angtemplate.html that has loaded the data from /apifetch? I realize this is a triple question involving first angular app-structure, second Django template syntax and folder structure, and thirdly url-patterns. I tried to follow the thinkster angular django tutorial, but was unable to connect the angular app to the website. My own theory is that inside the apitest Django application I create a few templates and in the static folder of that app I keep my angular apps, which I load as static into … -
Remove double quotes around string list
I have a list with dates in it. event_labels = [] for item in all_list: event_labels.append(str(item.event_created_at)) "['2018-05-18', '2018-05-17', '2018-05-16', '2018-05-15', '2018-05-14', '2018-05-13', '2018-05-12', '2018-05-11']" I am using this data to output for labels in chartjs. Problem is the sourrounding double quotes around the event_labels list. I have another list with just integers and it does not have the sourrounding quotes around the beginning and the end of the list. [26.0, 50.0, 27.0, 87.0, 46.0, 24.0, 18.0, 34.0] How do I output a string list without the double quotes at the beginning and end? -
how to change django default ForeignKey type from integer to string?
class NewStock(models.Model): stock_info = models.ForeignKey(Stock) stock_xcode = models.CharField(max_length=10, unique=True) class Stock(models.Model): stock_name = models.CharField(max_length=200) stock_id = models.CharField(max_length=10, unique=True, primary_key=True) In database,there will be a stock_info_id column and its type is integer. When stock_id starts with 0, such as 000001, It will be stock_info_id=1 and will fail to get stock_info because 1 is not found in column stock_id of Stock table. How can I specify an exact type for a ForeignKey. For this problem, things will be good if stock_info_id is CharField other than Integer. -
Angular app don't display on android browser

Recommended way to find the source of a query when using Django?
I'm having difficulties with locating the source of the queries which I see in my database logs. I'm using Django, so the actual queries are generated automatically which makes a simple "grep" ineffective. I'm thinking of patching the database cursors to append the current stacktrace to the query, something like: for conn in connections.all(): with conn.cursor() as c: ctype = type(c.cursor) orig_execute = ctype.execute def _patchedExecute(self, query, params=None): query = query + ' -- ' + traceback.format_stack() return orig_execute(self, query, params) ctype.execute = _patchedExecute orig_execute_many = ctype.executemany def _patchedExecuteMany(self, query, params=None): query = query + ' -- ' + traceback.format_stack() return orig_execute_many(self, query, params) ctype.executemany = _patchedExecuteMany What I'm wondering: is there a ready made solution for this? (seems like a somewhat common problem to have) if not, are there better solutions than the one presented above? (I'm not all that familiar with the Django internals) -
