Multiple apps in git remote and how to specify to one app
I was working with another developer on my git repository and he pushed his work to me after forking. When I wanted to deploy the change of our work to Heroku, with git push Heroku master I get the following error. Previously it was always working when I deploy. I need to specify the app, but don't know how. I am using Django and VScode. This is the following error: Error: Multiple apps in git remotes › Usage: --remote heroku-staging › or: --app radiant-escarpment-03215 › Your local git repository has more than 1 app referenced in git remotes. › Because of this, we can't determine which app you want to run this command against. › Specify the app you want with --app or --remote. › Heroku remotes in repo: › beneluxbilal (heroku) › radiant-escarpment-03215 (heroku-staging) I already tried with --app but it seems not to work for me. -
Django set default empty url
I'm trying to learn Django and I'm following Corey Shafer's tutorials (https://www.youtube.com/watch?v=a48xeeo5Vnk), but when I try to make two different pages, I get automatically directed to the one with an "empty address": In his: /Blog /urls.py it looks like this: from django.conf.urls import path from . import views urlpatterns = [ path('', views.home, name='blog-home'), path('about/', views.about, name='blog-about'), ] and when he goes to localhost:8000/blog/about, the page displays correctly When I try to imitate his code for blog/urls.py: from django.conf.urls import url from . import views urlpatterns = [ url(r'', views.home, name='blog-home'), url(r'^about/', views.about, name='blog-about'), ] the result of the localhost:8000/blog/about is the content of views.home, and not views.about. The following works correctly, when I write a name instead of an empty string: urlpatterns = [ url(r'^home', views.home, name='blog-home'), url(r'^about/', views.about, name='blog-about'), ] But I don't understand why it worked in a previous version, why it won't work now, and what could fix it -
Can I register a setting with a default value then use that setting in a model's field?
Is there any way I can @register_setting a setting with a default value, then use that setting in the default value for a field? I'd like my users to be able to specify a global tax rate default, but change it per location as needed. I'm already using a setting in another function on the same model, but believe the issue might be that it's not within a function in this case. I tried specifying default=8.25 in the constructor for default_sales_tax_rate, but that doesn't seem to work. I am getting a NameError: name 'DefaultSalesTaxRate' is not defined error. @register_setting class DefaultSalesTaxRate(BaseSetting): default_sales_tax_rate = models.DecimalField( max_digits=4, decimal_places=2, help_text="Default Sales Tax Rate", default=8.25 ) locations.models.LocationPage(Page) location_sales_tax_rate = models.DecimalField(max_digits=4, decimal_places=2, default=DefaultSalesTaxRate.objects.first().default_sales_tax_rate) I've tried assigning a variable sales_default to 8.25 if DefaultSalesTaxRate.objects.all().count() == 0, but that didn't work either. I am thinking maybe a hook or a signal to instantiate the setting in the table if it's not present, but am not sure where to hook into or where to call the signal. -
Django Staticfiles Is Saved In An Unexpected Location

How to set a field equal to a related model's foreign key on save() Django
I have three models, LocationPage, Customer, and WorkOrder. LocationPage has a city_name CharField. Customer and WorkOrder both have a customer_city and service_city ForeignKey to LocationPage, respectively.

Cloning a Django project has now meant that my CSS file isn't being found
I have been writing a project for a course I am doing but unfortunately the IDE I was using ran out of space and I had to start afresh by cloning my project to a new environment. My old environment had a CSS file that was being picked up correctly. When I cloned the project an extra base directory was created and now I have noticed that my CSS file isn't being picked up. I don't get any errors, but nothing in my CSS is being used. I assume that since it used to work it should be fairly simple to sort out but I cannot see what the problem is. If anyone has any ideas it would be greatly appreciated.

Django: How to order a queryset and move some items to end of the queryset
I have a queryset in my Django application: databytes_all = DataByte.objects Each item in the databytes_all queryset has many attributes but one of them is publish_date. I'd like to order the queryset by publish_date, however if publish_date is None, I'd like the item to be at the end of the queryset. This is what I'm trying but it's not working: databytes_all = DataByte.objects Make a queryset: filter out all of the publish dates that are None no_date = databytes_all.filter(publish_date=None) Make anohther queryset: exclude all of the items where publish date is none, then order the remaining items by publish date databytes_with_date = databytes_all.order_by('-publish_date').exclude(publish_date=None) Now combine the two querysets (however this doesnt work- the items with no publish date are first in the list when I want them to be last) databytes = databytes_with_date | no_date -

Django: Form Won't Add to Database
I can add to the database from the admin page but the form in template won't save. When I try to submit the form it just refreshes the form. views: def newPost(request): if request.method == 'POST': form = NewPost(request.POST) if form.is_valid(): form.save() return redirect('myposts') else: form = NewPost() return render(request, 'create/new_post.html', {'title_page': 'New Post', 'form': form}) Template: <form method="POST" class="input_group" action="" enctype="multipart/form-data"> {% csrf_token %} {{ form }} <div class="submit_container"> <input class="submit_btn" type="submit" value="Submit"> </div> </form> Form: class NewPost(forms.ModelForm): title = forms.CharField(widget=forms.TextInput(attrs={'class': 'form_input_text'})) product = forms.ChoiceField(widget=forms.Select(attrs={'class': 'form_input_select'}), choices=PRODUCT_CHOICES) caption_description = forms.CharField(max_length=1000, widget=forms.Textarea(attrs={'class': 'form_input_text', 'style':'resize:none;', 'rows': '3'})) full_description = forms.CharField(max_length=2000, widget=forms.Textarea(attrs={'class': 'form_input_text', 'style':'resize:none;'}), required=False) links = forms.CharField(max_length=2000, widget=forms.Textarea(attrs={'class': 'form_input_text', 'style':'resize:none;'}), required=False) release_date = forms.DateField(widget=forms.SelectDateWidget(attrs={'class': 'form_input_select_date'}, years=YEARS, empty_label="---"), required=False) display_image = forms.ImageField(widget=forms.ClearableFileInput(attrs={'class': 'form_img_btn'})) -
Does Lambda API/Django API slows down if called from the same machine?
I have both Django API and Lambda API which just sleeps for 4 seconds. When I execute the API for multiple times, the response time is so slow even though the code only runs for 4 seconds. Is this happening because I'm calling it from the same website? If yes what's the technical reason for API slowness when it's called from the same machine? -
