How do I make Heroku run yarn install or npm installl in a subdirectory
Let's say I have a project with the following directory structure project/ ... subdir/ node_modules package.json yarn.lock As you can see my yarn.lock, package.json, and node_modules are a subdirectory.

request parameter cannot be gotten
Request parameter cannot be obtained. I want to search whether "file" is in request parameter or not. I written the following code: def common_logic(request): data = request.POST.get('data', None) if 'file' in request.POST: file = request.FILES['file'].temporary_file_path() else: file = None return file However, when I set file parameter, always else statement is read. When I print out print(request.POST), <QueryDict: {'data': ['100']}> is shown so file parameter cannot be obtained. I want to get file parameter and search whether request.POST has file or not. Why can't I get file parameter? How can I get this? -

Django - cannot assign - must be an instance
I tried phrasing this question recently and got totally confused. I've extended the default user model with this in my models.py: class Biography(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) biography = models.TextField(max_length=500, blank=True,default='Details') I've included this in the forms.py: class EditProfileForm(forms.Form): first_name = forms.CharField(label='First Name') last_name = forms.CharField(label='Last Name') biography = forms.CharField(label='Biography', widget=Textarea(attrs={'rows': 5})) I have a view to edit the profile and want to add "biography" to it, but have absolutely no clue where to start. Here's the view: def edit_profile(request): user = request.user products = Product.objects.filter(user=user) form = EditProfileForm(request.POST or None, initial={'first_name':user.first_name, 'last_name':user.last_name}) if request.method == 'POST': if form.is_valid(): user.first_name = request.POST['first_name'] user.last_name = request.POST['last_name'] user.save() return render(request, 'profile.html', {'user':user, 'products':products}) context = {"form": form} return render(request, "edit_profile.html", context) I tried to replicate what is already there with this: def edit_profile(request): user = request.user products = Product.objects.filter(user=user) biography = Biography(user=user) form = EditProfileForm(request.POST or None, initial={'first_name':user.first_name, 'last_name':user.last_name, 'biography':user.biography}) if request.method == 'POST': if form.is_valid(): user.first_name = request.POST['first_name'] user.last_name = request.POST['last_name'] user.biography = request.POST['biography'] user.save() return render(request, 'profile.html', {'user':user, 'products':products}) context = {"form": form} return render(request, "edit_profile.html", context) I definitely missed the point somehow.

Django Social Auth not adding new user with saved Google credentials to the database
Scenario: Whenever a user tries to login via Google, if they're not already in the database, they're redirected back to an anon user state when they shouldn't be. If the user tries to login via Google with an existing email address (they're already in db), then they're authenticated just fine. In the request, even if the user authenticates via Google and is successful (gets an access token and everything), the request still believes it's an anonymous user. Working with Django Social Auth, and before this used to work but it doesn't any more. Code: views.py def index(request): try: # print(request.user) returns AnonymousUser even after authenticating profile = Profile.objects.get(email=request.user.email) return render(request, 'tablefor2/index-logged-in.html') except: return render(request, 'tablefor2/index-logged-out.html') HTML <a href="{% url "social:begin" "google-oauth2" %}"><button class="save btn btn-default">GET STARTED</button></a> settings.py MIDDLEWARE_CLASSES = [ 'django.middleware.security.SecurityMiddleware', 'whitenoise.middleware.WhiteNoiseMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.auth.middleware.SessionAuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', ] ROOT_URLCONF = 'tablefor2.urls' SOCIAL_AUTH_PIPELINE = ( 'social_core.pipeline.social_auth.social_details', 'social_core.pipeline.social_auth.social_uid', 'social_core.pipeline.social_auth.auth_allowed', 'social_core.pipeline.social_auth.social_user', 'social_core.pipeline.user.get_username', 'social_core.pipeline.social_auth.associate_by_email', 'social_core.pipeline.user.create_user', 'social_core.pipeline.social_auth.associate_user', 'social_core.pipeline.social_auth.load_extra_data', 'social_core.pipeline.user.user_details', ) TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [], 'APP_DIRS': True, 'OPTIONS': { 'context_processors': [ 'django.template.context_processors.debug', 'django.template.context_processors.request', 'django.contrib.auth.context_processors.auth', 'django.contrib.messages.context_processors.messages', 'social_django.context_processors.backends', 'social_django.context_processors.login_redirect', ], 'debug': DEBUG, }, }, ] LOGIN_URL = '/' LOGIN_REDIRECT_URL = '/' WSGI_APPLICATION = 'tablefor2.wsgi.application' SOCIAL_AUTH_ADMIN_USER_SEARCH_FIELDS = ['username', 'first_name', 'email'] SOCIAL_AUTH_USER_MODEL = 'tablefor2.Profile' … -

How to use Django Subquery inside Annotate and Sum
I am trying to calculate total revenue for a day. Each DailyTotal contains a count of items sold (items_sold) and a Price those items were sold that day (items_price) (every items is sold for the same price all day). That part is working, but now I need to convert multiply that value by the exchange rate for that day/country. rate = ExchangeRate.objects.filter( date=OuterRef('date'), country=OuterRef('country'))) calc_with_rate = Sum(F('items_sold') * F('items_price') * Subquery(rate.values('rate')), output_field=FloatField(),) results = DailyTotal.objects.filter(**query_filters).annotate( revenue=calc_with_rate) but I get: unsupported operand type(s) for +=: 'int' and 'NoneType I assume it is because rate.values('rate') is not returning a an int.. but I can't do rate.values('rate')[0] or I get: This queryset contains a reference to an outer query and may only be used in a subquery. so I am not sure how to complete this query? -

django allauth bootstrap - TemplateDoesNotExist
I am trying to get the bootstrap forms working for Django-Allauth, but I cannot get it working, and I cannot find much documentation on it. It references these bootstrap forms in the example of the django-allauth repo located at https://github.com/pennersr/django-allauth/tree/master/example. In the directions, it states that all you have to do to get the bootstrap forms working is install django-bootstrap-form and include "bootstrapform" in your INSTALLED_APPS in your settings file. I have done this in my project, but it still appears to be pulling templates from the /account folder instead of the /bootstrap folder. While debugging, I tried just replacing the login.html form in the /account folder with the one from the /bootstrap folder. In this case, I get a TemplateDoesNotExist exception at /accounts/login/ bootstrapform/form.html I figure if I can at least get the bootstrapform stuff working I can just replace the templates inside the /account folder and be fine... Any idea what may be happening? -
Django/MySQL: Making non-unique field unique fails even if field values are unique
I currently have this: class Committee(models.Model): # ...some fields... committee_xml_id = models.IntegerField() I need to make the field committee_xml_id unique, i.e. make it so: class Committee(models.Model): # ...some fields... committee_xml_id = models.IntegerField(unique=True) I have also tried making it so: class Committee(models.Model): # ...some fields... committee_xml_id = models.IntegerField(unique=True, db_index=False) Alas, the result is the same. Having run ./manage.py makemigrations and subsequently, ./manage.py migrate, the problem is this: django.db.utils.OperationalError: (1061, "Duplicate key name 'appname_committee_committee_xml_id_d1210032_uniq'") At first glance, it seems like the problem is that there is already non-unique data in the table, but the problem is precisely that there isn't. There are only 45 rows in the table, and the field committee_xml_id contains only unique entries. The following query gives no results, as expected when there are no duplicates: SELECT com.committee_xml_id, COUNT(*) FROM appname_committee AS com GROUP BY com.committee_xml_id HAVING COUNT(*) != 1 For rigor, here is the same query without the HAVING-condition, showing clearly that there are indeed no duplicates: SELECT com.committee_xml_id, COUNT(*) FROM appname_committee AS com GROUP BY com.committee_xml_id Result is: # committee_xml_id, COUNT(*) 78, 1 79, 1 124, 1 125, 1 129, 1 130, 1 131, 1 132, 1 133, 1 134, 1 137, 1 139, 1 140, 1 … -

Django save related ManyToMany model
