Django can't map url to view using include method

What is the easiest way to require the user to fill in default fields of the User model like first name and last name in Django in UserCreationForm?
I am using Django built-in authentication views and form to create a registration/login system, and I'm using the UserCreationForm to register a user but only the username is required.

How to modify Page model view in wagtail admin?
Background: I would like to enhance a page instance during an admin page view with some admin request related information (some pre-population in general). Basically I would need some function like "get_queryset", but not for list view, just for edit view. In my older question related to a similar problem: Wagtail - how to preopulate fields in admin form? I was provided with instructions to use something called CreatePageView However, I cannot import it. Furthermore, I cannot even found any mention about that in google if I search: Wagtail +CreatePageView The closest thing I found is https://docs.wagtail.io/en/v2.1.1/reference/contrib/modeladmin/create_edit_delete_views.html but the page also states: NOTE: modeladmin only provides ‘create’, ‘edit’ and ‘delete’ functionality for non page type models (i.e. models that do not extend wagtailcore.models.Page). If your model is a ‘page type’ model, customising any of the following will not have any effect I am quite confused. What should I do if I need to customize the admin view for Page model extension? I studied the wagtail source codes for Model.admin and Page and I have not found any way. Any ideas? The related code simplified: wagtail hooks: class ItemAdmin(ModelAdmin): pass # some function override here maybe? models: class ItemPage(Page): pass # … -
Unable to connect to gmail smtp linode django apache2 setup
Hello im having difficulties connecting to google smtp server. The context is that whenever a user fills in a form , my program will automatically email me the feedback to my gmail account. Everything is working except for the fact that the program is stuck within the send_mail function. I have tried doing this : telnet smtp.gmail.com 25 Trying 2404:6800:4003:c03::6c... Which will eventually result in a time out. Here is some of my code: settings.py EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend' EMAIL_HOST = 'smtp.gmail.com' EMAIL_HOST_USER = 'xxxx@gmail.com' EMAIL_HOST_PASSWORD = 'xxxxxx' EMAIL_PORT = 465 EMAIL_USE_TLS = False EMAIL_USE_SSL = True DEFAULT_FROM_EMAIL = EMAIL_HOST_USER SERVER_EMAIL = DEFAULT_FROM_EMAIL As per out of the box from wagtail(django cms package) I thought it might have to do with my UFW blocking it , however i have tried disabling the UFW and restarting apache2 . This unfortunately does not help. ufw status Status: active To Action From -- ------ ---- 22/tcp ALLOW Anywhere 80/tcp ALLOW Anywhere 443/tcp ALLOW Anywhere 22/tcp (v6) ALLOW Anywhere (v6) 80/tcp (v6) ALLOW Anywhere (v6) 443/tcp (v6) ALLOW Anywhere (v6) I am really lost!

Vectorizing Function using Pandas Dataframe result in KeyError
I am still new to Pandas dataframe and I'm trying to vectorize the following loop functions because while it gets the job done, iterating a 30,000 rows dataframe using iterrows() is not viable at all header = data_reader.columns.values.tolist()[1:] series_list = [] # New row in Timeseries table for datetime_index, row in data_reader.iterrows(): for i in range(0, len(row)-1): metrics = Metrics.objects.get(name=header[i]) print(metrics) try: val = float(row[i]) series_list.append(Timeseries(timestamp=datetime_index, parameter=metrics, float_val=val, status=None, device_id=metadata)) except ValueError: series_list.append(Timeseries(timestamp=datetime_index, parameter=metrics, float_val=None, status=row[i], device_id=metadata)) Timeseries.objects.bulk_create(series_list) Thus I've looked up on Pandas/NumPy Array Vectorization and how it can shorten the time complexity of a function. I am trying to convert the above function into the vectorized version and this is what I've got so far header = data_reader.columns.values.tolist()[1:] series_list = [] data_reader = data_reader.reset_index() for i in range(1, len(header)): series_list.append(insertion(header, series_list, data_reader['datetime'].values, data_reader[i].values, metadata)) Timeseries.objects.bulk_create(series_list) def insertion(header, series_list, datetime, df_col, metadata): metrics = Metrics.objects.get(name=header[i]) print(metrics) try: val = df_col series_list.append(Timeseries(timestamp=datetime, Parameter=metrics, value=val, status=None, device_id=metadata)) except ValueError: series_list.append(Timeseries(timestamp=datetime_index, Parameter=metrics, value=None, status=val, device_id=metadata)) return series_list However when I try to run the code I always get KeyError: 1 error message. Any idea on how I can vectorize my function and the cause of the error message? -
