How to run a Django project without a manage.py file?
I'm not experienced with Django. I just want to get this project running on a localhost (on Mac). Normally I run python manage.py runserver inside a virtualenv but I can't do that without a manage.py file! I must be doing something obviously wrong if this project has 264 GitHub stars. https://github.com/shacker/django-todo How can I make this work? -

django-tables2 exclude & field not working
I'm new to django and stumbling through creating my first site. I'm using django-tables2 to display a table and it appears to be working (the table shows up, it's sortable). Except I can't seem to customize anything. Exclude, field and sequence don't work. Can't change column verbose names. TABLE: import django_tables2 as tables from sl_overview.models import DailyslSumm class slsummTable(tables.Table): class Meta: model = DailyslSumm exclude = ('index') VIEW: class sl_summ(SingleTableView): model = DailyslSumm context_object_name = 'slsummdb' table_class = slsummTable TEMPLATE: {% load render_table from django_tables2 %} {% render_table slsummdb %} The exclude in the code above doesn't work. The column is still there. Using field doesn't adjust columns either. I'm sure I'm missing something simple, thanks for any help. -

Django custom model class functions- .save()
Can you define a function in a Django model that will use the .save() function. Class Restaurant(models.Model) name = models.CharField(max_length=25) rating = models.PositiveIntegerField(validators=[MaxValueValidator(100), MinValueValidator(0)], default=50) def change_rating(self, value) self.rating += value self.rating.save() Will this work? Is this best practices? Is it better to accomplish this in views like so: *views.py def change_rating(name, amount): res = Restaurant.objects.get(name=name) res.rating += amount res.save() Thanks for the help! -

django.db.utils.IntegrityError: update or delete on table when deleting a record
I use django and postgress and have a very odd exception. I have a model object called ProductModel (with upc as a unique_id).

Can't get my django program to increment values that are on the server
I am very new to Django and I found a lot on other sites but nothing that really could help me.

Django, Create-react-app, Heroku
I have 3 folders in a Django web application. The folders are as follows: the folder that contains settings.py(project), the folder that contains models.py(application), and a folder that contains a front end react application created by create-react-app. I would like to build the react front end, copy the build artifacts into a static folder and then run the django application on heroku, but they have made this process practically impossible with my current folder structure. The alternative is to flatten the react application out and have build, src, node_modules, packagejson etc etc etc all at the root of the project, but this seems really bad. some config in settings.py: STATICFILES_DIRS = ( os.path.join(PROJECT_ROOT, 'static'), os.path.join(BASE_DIR, 'front-end/build/static') ) what i run locally inside front-end: npm run build what i'm returning from views: def index(request): return HttpResponse(loader.get_template('build/index.html').render()) #above line returns index.html that is generated by npm run build How do I deploy the project described above to Heroku so it can find all static resources? -

Issue connecting ESP8266 to Raspberry Pi Django Webserver
I'm having an issue getting my ESP8266 returning the correct information from a Django view on a local webserver (running off of a Raspberry Pi). I'm a fairly new developer - so any help would be appreciated! Here's the situation, my code, and my thought process so far: I can GET data from my app on any computer in my network using CURL and it returns the correct information. But if I try to GET data from my app through the ESP8266 it does not work. The ESP8266 DOES let me GET data from an outside website, though. So I know the ESP8266 is 1) working, 2) connected to my wifi, 3) capable of GET requests to outside websites. But for some reason it's not getting the data back from an app hosted on my local server. Here's what I have so far: views.py: @csrf_exempt def test_light(request): if request.method == "GET": print("Get Request Incoming") response_string = "Responding from the Django View" return HttpResponse(response_string) if request.method == "POST": request_dict = json.loads(request.body) print(request_dict) return HttpResponse(status=204) return HttpResponse(status=400)``` Now when I run the following CURL command from any computer on my local network: Terminal: curl “http://pi.local:8000/planner/test-light/" I get the following response on my … -

How to upload images to a public website and have it processed by a remote computer?
I have a computer that can be accessed remotely, and I would like a public user to be able to upload an image to a website and have it processed by a specific python code on the remote computer (which requires the computer's GPU resources). This is the desired flow of events: 1- User accesses the website; 2- User uploads an image to the website; 3- The website sends the image to the remote computer; 4- The remote computer runs a python code on the image and creates a new image; 5- The remote computer sends the new image to the website where it is displayed to the user. Is there an easy way to achieve this ? Thanks! -

MySQL encoding from Latin-1 to UTF-8
For a very long time i was suffering form the Latin-1 encoding in My Django web application DB causing this error when trying to select a matching string using LIKE : -- UnicodeEncodeError:'latin-1' codec can't encode character-- i've tried every solution from setting (charset='utf8') in the connection to applying cursor.execute("set names 'utf8'") before my actual query but nothing seams to work.

Store boolean variable in url dispatching
The following url definition should pass whether results/ is present in the url: url(r'^(?P<question_id>[0-9]+)/(?P<results>(results/)?)shorten/$', views.shorten, name='shorten') Currently it passes results/ or None which is sufficient for a simple: if results: pass But it would be more elegant to have True and False. How could this be done?
