Error ! The following packages have unmet dependencies: mysql-server
I tried to install mysql on my ubuntu16.04 for a django project. The installation has some problem with some existing files, getting the error: mysql-server is already the newest version (5.7.19-0ubuntu0.16.04.1). You might want to run 'apt-get -f install' to correct these: The following packages have unmet dependencies: mysql-server : Depends: mysql-server-5.7 but it is not going to be installed E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution) I tried, sudo apt-get -f install which gives error: Preparing to unpack .../mysql-server-5.7_5.7.19-0ubuntu0.16.04.1_amd64.deb ... grep: /etc/mysql/: No such file or directory Aborting downgrade from (at least) 10.2 to 5.7.

Django crispy forms - creating a form in home.html and getting an error
I have built a crispy form from a tutorial (https://godjango.com/29-crispy-forms/) and am getting an error that I believe means I need to define a URL in the urls.py. I also get the sense that there may be more than one issue going on - I am still trying to make this work and will continue to research it but I am quite new to Django and Python so struggling on this. Any guidance gratefully received. Here's the error: Failed lookup for key [form] in "[{'True': True, 'False': False, 'None': None}, {}, {}, {'view': <django.views.generic.base.TemplateView object at 0x10faa03c8>, 'home_url': '/'}]" For reference here are the files: forms.py from django import forms from crispy_forms.helper import FormHelper from crispy_forms.layout import Submit, Layout, Field from crispy_forms.bootstrap import ( PrependedText, PrependedAppendedText, FormActions) class SimpleForm(forms.Form): username = forms.CharField(label="Username", required=True) password = forms.CharField( label="Password", required=True, widget=forms.PasswordInput) remember = forms.BooleanField(label="Remember Me?") helper = FormHelper() helper.form_method = 'POST' helper.add_input(Submit('login', 'login', css_class='btn-primary')) class CartForm(forms.Form): item = forms.CharField() quantity = forms.IntegerField(label="Qty") price = forms.DecimalField() helper = FormHelper() helper.form_method = 'POST' helper.layout = Layout( 'item', PrependedText('quantity', '#'), PrependedAppendedText('price', '$', '.00'), FormActions(Submit('login', 'login', css_class='btn-primary')) ) class CreditCardForm(forms.Form): fullname = forms.CharField(label="Full Name", required=True) card_number = forms.CharField(label="Card", required=True, max_length=16) expire = forms.DateField(label="Expire Date", input_formats=['%m/%y']) ccv … -
Error when running a Django server
I am using Django 1.8 and I get the following error: WARNINGS: ?: (1_7.W001) MIDDLEWARE_CLASSES is not set.

django domain setup and routing schema
Can anyone give me a short walkthrough (yes, I know that's asking a lot... I'm completely lost) of how to properly setup different domains using a single django project? Or... point me in the right direction / some insight to my questions below... I've searched around and looked at various app solutions, apache stuff, etc but still don't have a clear understanding. Specifically, each (main) app in my project is on a different domain. I have an app for news, job posts, etc and these would be on (name)news.io, (name)jobs.io, etc. In my settings.py file currently I'm using django-multiple-domains and have the MULTIURL_CONF set to point to each app based upon the domain name. As I understand it.... i can just set up the project on my domains using the same settings file since it will use this routing schema rather than the suggested route of multiple different settings file for each domain based upon the middleware that django-multiple-domains uses. Now, here's where I get confused on the URL routing.... In an app we typically include the urls inside the main urls.py file in the root app folder for our project to creating a routing schema for the entire site … -

django - making .create() support writable nested fields?
So in Django, .create() does not support writable nested fields. However, I have a nested field in my project. I looked at this question, which was helpful, but I'm now getting a ValueError at /transactions/ invalid literal for int() with base 10: 'Product001'. As far as I can tell, this is caused by the line in serializer.py that reads product = Product.objects.get(pk=validated_data.pop('sku')) specifically, the 'sku' value I have in there. My question is, what value should I put in there to replace 'sku'? The answer to the question I based my code on used 'event', but that's not part of my models in my project. I've also tried using 'product', and got a TypeError that sadi "int() argument must be a string, a bytes-like object or a number, not 'collections.OrderedDict'". serializers.py from .models import Product, Family, Location, Transaction from rest_framework import serializers class LocationSerializer(serializers.ModelSerializer): class Meta: model = Location fields = ('reference', 'title', 'description') class FamilySerializer(serializers.ModelSerializer): class Meta: model = Family fields = ('reference', 'title', 'description', 'unit', 'minQuantity') class ProductSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = Product fields = ('sku', 'barcode', 'title', 'description', 'location', 'family') depth = 1 class TransactionSerializer(serializers.ModelSerializer): product = ProductSerializer() class Meta: model = Transaction fields = ('sku', 'barcode', … -

test django app with multiple domains locally
How would I go about testing a django app which uses multiple domains locally? Each app is on a different domain (i.e. - (somename)news.io, (somename)jobs.io, ...). I'm trying to test my url routing schema as well as session data being shared across the domains. I tried setting up apache, xampp, and using virtualhosts on windows but this didn't work for me - I couldn't figure out how to set up the virtualhosts (to fake the domains) and get my app served to them. So, looking for another route for testing. -
Sorting a table by clicking the table head column in Django Web
So I have a website in django. I have a table with a few colums like ServerName,IP etc.. I would like to have the header of the columns to sort the entire column. For example when I click the ServerName column it will order all the items by ABC order of the ServerName. I have heard of django-sorting-bootstrap but the guide seem complicated. Is there any easier or good guide to do that? the idea is to click with the arrow on the head and it will sort it out (It will be like a link). index.html table- <div class="container"> <br> <center><h1>DevOps Server List</h1></center> <br> <form method='GET' action=''> <input type='text' name='q' placeholder='Search Item'/> <input type='submit' value='Search' /> </form> <table class="table table-hover"> <thead> <tr> <th> Server Name </th> <th> Owner </th> <th> Project </th> <th> Description </th> <th> IP Address </th> <th> ILO </th> <th> Rack </th> <th> Status </th> <th> </th> </tr> </thead> <tbody> {% for server in posts %} <tr> <div class ="server"> <td>{{ server.ServerName }}</td> <td>{{ server.Owner }}</td> <td>{{ server.Project }}</td> <td>{{ server.Description }}</td> <td>{{ server.IP }}</td> <td>{{ server.ILO }}</td> <td>{{ server.Rack }}</td> <td>{{ server.Status }}</td> <td> <button type="button" class="btn btn-primary" data-toggle="modal" href="#delete-server-{{server.id}}" data-target="#Del{{server.id}}">Delete <span class="glyphicon glyphicon-trash" </span></button> … -
Why Django serialize returns string
I have problem with returning something browsable form serializers.serialize.

I tried few more things: >>> me = serializers.serialize('json', [game_frame, ], fields=('Frame', 'FrameRow')) AttributeError: 'QuerySet' object has no attribute '_meta' My question: is it normal to return string? How I can browse the object. In fact I'm using it with AJAX but its the same. json.game_frame[0] returns '['. I need to be able to get the elements separately as normal dict or list. What is going on? -

django admin edit model select/prefetch_related?
I have a Django website, with model Event, lets say: class Event(models.Model): home = models.ForeignKey('Team', related_name='%(class)s_home') away = models.ForeignKey('Team', related_name='%(class)s_away') ... class Team(models.Model): name = models.CharField("team's name", max_length=100) Using ForeignKeys for this was a bad idea, but anyway, how to make this usable in Django Admin page? In admin edit event page, a ton of foreign keys is fetched for this: http://127.0.0.1:8000/admin/event/event/116255/ It produces tons of selects like: SELECT "event_team"."id", "event_team"."name" FROM "event_team" WHERE "event_team"."id" = 346; and page dies. I was playing with these: class EventAdmin(admin.ModelAdmin): list_display = ('id', 'home', 'away', 'date_game', 'sport', 'result') search_fields = ['home__name', 'away__name'] list_select_related = ( 'home', 'away', 'league', 'sport', ... ) def get_queryset(self, request): return super(EventAdmin, self).get_queryset(request).select_related(*self.list_select_related) admin.site.register(Event, EventAdmin) But no luck. -

How to send back the tokens to android using Firebase Auth
I am developing an Android app which uses Firebase and my own server running Django. What I intend to do is, I want to first authenticate the user using android app to the django server which then generates the custom tokens as specified in firebase docs. Then I want to send the generated custom token back to the android. My question is how to send that custom token back to android? I tried to send as JSON object. But it says JWT are not JSON serializable. I passed the username and password from android app as json object and authenticated with my django server. Here is my minimal Django code: import firebase_admin from firebase_admin import credentials from firebase_admin import auth cred = credentials.Certificate("firebase-admin.json") default_app = firebase_admin.initialize_app(cred) def validateuser(request): json_data=json.loads(request.body.decode('utf-8')) try: // I verify the username and password and extract the uid uid = 'some-uid' custom_token = auth.create_custom_token(uid) result={'TAG_SUCCESS': 1, 'CUSTOM_TOKEN': custom_token } except: result={'TAG_SUCCESS': 0, 'CUSTOM_TOKEN': '0'} return HttpResponse(json.dumps(result), content_type='application/json') But it says the custom token is not JSON serializable. Is it not the way to do like this? How do I send the custom token back to the android app?

django - TemplateDoesNotExist error
I am working through this Getting started with Django Rest Framework by Building a Simple Product Inventory Manager tutorial. At the end the tutorial, it says that I "should now be able to run your server and start playing with diffrent API endpoints". However, when I run the server, all I'm getting is a TemplateDoesNotExist error. At no point in the tutorial does it mention creating templates (and this is eventually going to connect to an Angular 2 frontend, as shown in this tutorial), so I'm confused at to whether this is an error in my code, or if the tutorial left a step out.

Django importing app models in non-app package
I have a django project with two apps, and I also want to have a scheduled job via Heroku's job scheduling tools which handles some regular database operations. In order to handle the tasks of the scheduled job, I have a separate package in my top-level django project folder. This package requires access to the models as defined in my apps. However, I cannot find out how to import the models from my apps. The structure is as follows: myproject | | myproject | | __init__.py | | ... | myapp1 | | __init__.py | | models.py | | ... | myapp2 | | __init__.py | | models.py | | ... | customjobmodule | | __init__.py | | ... | ... I have tried several ways of importing using sys.path.append() but none of them seem to work. They all say there is no module named myapp1.models import os import sys cwd = os.getcwd() sys.path.append(cwd + '/../myapp1/') from myapp1.models import Model1 ImportError: No module named myapp1.models Is there a way to do this? When searching around I have found plenty of information about using models between django apps, but not using them outside of the django framework altogether. -
Why Django Rest Framework SessionAuthentication doesn't require csrf for unauthenticated users?
I've found this in Django Rest Framework docs: CSRF validation in REST framework works slightly differently to standard Django due to the need to support both session and non-session based authentication to the same views. This means that only authenticated requests require CSRF tokens, and anonymous requests may be sent without CSRF tokens By default DRF uses those authentication classes: 'DEFAULT_AUTHENTICATION_CLASSES'= ( 'rest_framework.authentication.SessionAuthentication', 'rest_framework.authentication.BasicAuthentication' ), What would be the problem in supporting both session and non-session based authentication while checking csrf token for unauthenticated users (using SessionAuthentication class)? -

When I add the memcached_status to my installed apps in settings.py, I get this error when I try to open the Django admin page: Internal Server Error: /admin/ Traceback (most recent call last): File "/Users/comp/Desktop/Dev/educa/lib/python3.6/site- packages/django/core/handlers/exception.py", line 41, in inner response = get_response(request) File "/Users/comp/Desktop/Dev/educa/lib/python3.6/site- packages/django/core/handlers/base.py", line 217, in _get_response response = self.process_exception_by_middleware(e, request) File "/Users/comp/Desktop/Dev/educa/lib/python3.6/site- packages/django/core/handlers/base.py", line 215, in _get_response response = response.render() File "/Users/comp/Desktop/Dev/educa/lib/python3.6/site- packages/django/template/response.py", line 107, in render self.content = self.rendered_content File "/Users/comp/Desktop/Dev/educa/lib/python3.6/site- packages/django/template/response.py", line 84, in rendered_content content = template.render(context, self._request) File "/Users/comp/Desktop/Dev/educa/lib/python3.6/site- packages/django/template/backends/django.py", line 66, in render return self.template.render(context) File "/Users/comp/Desktop/Dev/educa/lib/python3.6/site- packages/django/template/base.py", line 207, in render return self._render(context) File "/Users/comp/Desktop/Dev/educa/lib/python3.6/site- packages/django/template/base.py", line 199, in _render return self.nodelist.render(context) File "/Users/comp/Desktop/Dev/educa/lib/python3.6/site- packages/django/template/base.py", line 990, in render bit = node.render_annotated(context) File "/Users/comp/Desktop/Dev/educa/lib/python3.6/site- packages/django/template/base.py", line 957, in render_annotated return self.render(context) File "/Users/comp/Desktop/Dev/educa/lib/python3.6/site- packages/django/template/loader_tags.py", line 177, in render return compiled_parent._render(context) File "/Users/comp/Desktop/Dev/educa/lib/python3.6/site- packages/django/template/base.py", line 199, in _render return self.nodelist.render(context) File "/Users/comp/Desktop/Dev/educa/lib/python3.6/site- packages/django/template/base.py", line 990, in render bit = node.render_annotated(context) File "/Users/comp/Desktop/Dev/educa/lib/python3.6/site- packages/django/template/base.py", line 957, in render_annotated return self.render(context) File "/Users/comp/Desktop/Dev/educa/lib/python3.6/site- packages/django/template/loader_tags.py", line 177, in render return compiled_parent._render(context) File "/Users/comp/Desktop/Dev/educa/lib/python3.6/site- packages/django/template/base.py", line 199, in _render return self.nodelist.render(context) File "/Users/comp/Desktop/Dev/educa/lib/python3.6/site- … -
Django: custom users
I have following users in my Django applications: 1. Normal user (UUID, email, name, address, password) 2. Remote application (UUID, name, generated random secret) 3. (other type of remote application) The authentication for the Normal user would be with webpage email + password The authentication for the Remote application would be with UUID + random secret with JSON to ask for the temporary token I do not know how to handle this in Django. I wanted to create AuthBaseUser from AbstractBaseUser like: class AuthBaseUser(AbstractBaseUser, PermissionsMixin): pk = models.UUIDField(primary_key=True, unique=True, default=uuid.uuid4, editable=False,) name = models.CharField(_('name'), max_length=128, blank=False) typ = models.CharField(max_length=16, choices=USER_TYPES, default='normaluser',) date_joined = models.DateTimeField(_('date joined'), auto_now_add=True, default=timezone.now) last_login = models.DateTimeField(_('last login'), auto_now_add=True) is_active = models.BooleanField(_('active'), default=True) Then I wanted to create a RemoteAppUser and NormalUser with 1:1 mapping like this: class NormalUser(AuthBaseUser): user = models.OneToOneField(AuthBaseUser, on_delete=models.CASCADE) email = models.EmailField(_('email address'), unique=True) is_superuser = models.BooleanField(_('superuser'), default=True) #password = #not decided yet what to add here; for remote app we will have 256b of SHA256's random generated value EMAIL_FIELD = 'email' REQUIRED_FIELDS = AuthBaseUser.REQUIRED_FIELDS.append(['email', 'password', ]) objects = NormalUserManager() def __init__(self, *args, **kwargs): super(AuthBaseUser, self).__init__(*args, **kwargs) def __str__(self): return self.get_username() def get_full_name(self): return self.get_username() def get_short_name(self): return self.get_username() Of course, I have … -
Django RedirectView to my another project's url as default
I started to build the django tutorial app on the MDN website yesterday. And used RedirectView.as_view() to redirect my base urls to the app url as the tutorial said and it worked fine. # MDN Project urls.py urlpatterns = [ url(r'^admin/', admin.site.urls), url(r'^catalog/', include('website.urls')), url(r'^$', RedirectView.as_view(url='/catalog/', permanent=True)), ] + static(settings.STATIC_URL, document_root=settings.STATIC_ROOT) In the catalog app: # Catalog app urls.py urlpatterns = [ url(r'^$', views.index, name='index'), url(r'^about/$', views.about, name='about'), url(r'^contact/$', views.contact, name='contact'), url(r'^products/$', views.products, name='products'), ] But today i started another project in django and tried to make my base url include directly my app and it still redirects to the MDN projects url ('/catalog/') even there is no code that says to do that. What is wrong with my code? # Projects urls.py urlpatterns = [ url(r'^admin/', admin.site.urls), url(r'^/', include('myapp.urls')), ] In my app: # My App's urls.py urlpatterns = [ url(r'^$', views.index, name='index'), ]
