Django Multiple Forms from differents models
i m quite new with Django but i m stuck since a day on a problem that i can t solve. I have to create forms with a lot of fields. The fields comes from different models and i want to save them all at once. I want to display it with a slick so the user experience will be better and not overwhelmed by the amout of fields to fill. The slick part is not a problem. My problem is to render multiple form separated in different div on the same page. In this i want to display the candidateDetails form not only the candidate one. here my actual code for only one form that is working.

ProgrammingError: 1064 while executing inspectdb with django and mysql database
I have two databases configured in settings.py: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql', 'NAME': 'postgres', 'USER': 'postgres', 'PASSWORD': 'password', 'HOST': '127.0.0.1', 'PORT': '5432', }, 'db2': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'database', 'USER': 'user', 'PASSWORD': 'password', 'HOST': 'ip address', 'PORT': 'port', } } The server which hosts db2 uses mysql 4.1.2.

Heroku aggregate metrics from JSON logs
I have a Django application running on Heroku with json logs outputted to papertrail in the following format (examples): {"message_type":"profile", "method":"a", "runtime":1000, "timestamp: 1570524933} {"message_type":"profile", "method":"b", "runtime":1020, "timestamp: 1570524934} {"message_type":"profile", "method":"a", "runtime":2020, "timestamp: 1570524934} For instance, I want to construct a chart on Grafana that can show the mean runtime of methods a and b across the day but am unsure as to how I can run select or run aggregation functions such as (mean, max, min, etc.) using data from papertrail. So far I have looked at setting up an alert on papertrail for certain log criteria that will then ping Graphite Grafana, however this only gives the summed number of events. Does anyone have any input on this can be achieved? -

How To Provide A Class To Fields In A Django Template?
I was working a project on mine, in which I needed to provide a class to a field in form which is a input box, but don't know how to do so.

Django Storages: use 2 media sources
In my Django APP I use Dropbox API for media files. This are the settings. MEDIA_URL = '/media/' MEDIA_ROOT = os.path.join(BASE_DIR, "media") DEFAULT_FILE_STORAGE = 'storages.backends.dropbox.DropBoxStorage' DROPBOX_OAUTH2_TOKEN = 'my_token' DROPBOX_ROOT_PATH = '/my_app/' I want to ADD another storage in Google CDN, keeping Dropbox.

Setting header name in list_filter when referencing foreign key in Django
I have a ProductType and Transaction model. The Transaction model references ProductType using a foreign key. I use list_filter to filter on ProductType in the admin environment for the Transaction model. However, the header name in the list filter is correct, since it calls the filter option "By name" instead of "By product type". How can I update this header name to "By product type"? models.py class ProductType(models.Model): name = models.CharField(max_length=20) class Transaction(models.Model): product_type = models.ForeignKey(ProductType, on_delete=models.CASCADE) admin.py @admin.register(Transaction) class TransactionAdmin(admin.ModelAdmin): list_filter = ['product_type__name'] -

So as there are currently 3 months (08, 09, 10), the graph should only show 3 data points. Sorry if this doesn't make sense, I am not sure what the best way to explain it is. -
