FileNotFoundError: [Errno 2] No such file or directory: 'corpus_or_AB_FMC.xlsx'
I have a directory which contains a lot of excel files. My aim is to read all those excel files and extract some information in them. I used the script below to read the directory but I am still getting an error.

All paths open a single page
I am new to Django and doing something wrong. I've tried many templates and examples and always run into the same problem. No matter what path I try to use, I get the same file. Settings.py INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', #my apps 'strategicplan.apps.StrategicplanConfig', 'house.apps.HouseConfig', ] Main site urls.py from strategicplan import views as sp_views from house import views as house_views urlpatterns = [ path('house/',house_views.index), path('strategicplan/',sp_views.index), ] house/urls.py from django.urls import path from house import views urlpatterns = [ path('', views.index, name='index'), ] house/templates/index.html <!DOCTYPE html> <html lang="en"> <head> {% block title %}<title>Houses</title>{% endblock %} </head> <body> house </body> </html> strategicplan/urls.py from django.urls import path from strategicplan import views urlpatterns = [ path('strategicplan/', views.index, name='index'), ] strategicplan/templates/index.html <!DOCTYPE html> <html lang="en"> <head> {% block title %}<title>strategic plan</title>{% endblock %} </head> <body> strategic plan </body> </html> No matter what I put in the url http://127.0.0.1 or http://127.0.0.1/house or http://127.0.0.1/stategicplan, I get the strategicplan/index.html page. Both http://127.0.0.1 and http://127.0.0.1/house end up with http://127.0.0.1 in the address bar, but still show the strategicplan page. The http://127.0.0.1/strategicplan page holds the correct address in the address bar, which is also the correct page. Thanks!! -

ImportError when trying to use Django
apologies if this question has been asked a ton, I'm sure it has, and I've been trying for days to figure this out, but I can't wrap my head around it. I've been developing in Python for over 1.5 years, so I'm not a complete beginner. I can't get Django to work in my command prompt. An example is, when I try to use py .\manage.py makemigrations this is what I get: Traceback (most recent call last): File ".\manage.py", line 11, in main from django.core.management import execute_from_command_line ModuleNotFoundError: No module named 'django' The above exception was the direct cause of the following exception: Traceback (most recent call last): File ".\manage.py", line 22, in <module> main() File ".\manage.py", line 13, in main raise ImportError( ImportError: Couldn't import Django.

How to filter the list of a foreign_key form and change the display name in Django admin?
I know I can get the list of values that is displayed in a ForeignKey form in my add/change form filtered based on a queryset if I override the get_form method. But how can I also change the display name of these fields? I know I can use formfield_for_foreignkey method but then I don't have the object to filter the queryset. I couldn't use both because one overrides the other. def get_form(self, request, obj=None, **kwargs): form = super().get_form(request, obj, **kwargs) value = ... #some value used for filtering form.base_fields['some_field'].queryset = ( MyModel.objects.filter(other_field=value) .order_by('name') ) return form Also, when I use the get_form with the queryset filtered, if I am accessing a change_form page, that field is blank even though the instance of the model that I am editing has a value for it. Any thoughts? Reference: formfield_for_foreignkey -

django verbose_name remove remove capitalization
How to remove the capitalization of verbose name? a field in models.py betondeckung= models.FloatField(null=True, blank=True, default=None, verbose_name='Betondeckung [cm]') is processed in a html-table with django template language (tempalate.html) using <th scope="col" style="text-align:left">{{ model|get_verbose_field_name:field}}</th> where the following filter is used from templatetag.py @register.filter def get_verbose_field_name(instance, field_name): """ Returns verbose_name for a field. """ return instance._meta.get_field(field_name).verbose_name.title() The problem is that django produces a html that is sent to the browser with: Betondeckung [Cm] Every single word is capitalized, which is not correct for german and here even "cm" becomes "Cm". I tried with css, but the capitalization is already in django. Setting all to lower case using css can also be wrong. Any idea how to switch off the capitalization of the verbose name (in django)? -

Boolean Filter on Django Admin
I'm trying to build a filter that corresponds to the has_images method on my Django admin, but I can't because it strictly says that has_images is not a field of the model.

I'm working on translation (French to German) of some messages my app send through Django Api. My problem was that translation worked only if i put LANGUAGE_CODE="de-de". So i thought was a problem with lazy translation. I found keep_lazy() decorator but, being really a baby web dev, i can't find the way to incorporate keep_lazy() on my existing decorator. Here is my py file sending message through api request (create document here) : @method_decorator( reponse_toast_decorator(Toast(message=gettext("Votre nouveau document a été créé.")), data_field_name="document"), name="create", ) Here is my function from utils : def reponse_toast_decorator(toast=None, data_field_name=""): def decorator(func): @wraps(func) def wrapper(*args, **kwargs): response = func(*args, **kwargs) if not isinstance(toast, Toast): raise ValueError("L'argument 'toast' doit être une instance de la classe Toast") if isinstance(response, Response): if response.status_code == status.HTTP_204_NO_CONTENT: response.status_code = status.HTTP_200_OK if response.data is None: response.data = {} if not data_field_name: response.data.update({"toast": toast.data}) return response response.data = {data_field_name: response.data, "toast": toast.data} return response return wrapper return decorator Being a baby web dev, i can't find the way to incorporate -
Do I have to use Django Models to use the API?
We are migrating our intranet application and have decided to choose the Django framework. We control all of our database via source control and managed scripts, so we do not use the migrate feature to create tables for us. Views and Tables can change, all business logic is held in the database. I want to make Django API endpoint which is basically select * from my_table_or_view; and Django can return a JSON response with the column names and values. Some database tables have close to 100 columns each so I don't want to write out each and every field name and type just to return a query. What happens if we add another column to the view - will I have to update it in Django as well? What if I change the column type - will my application fail as well? The frontend is written in VueJS - it makes a request to the API endpoint and should use the columns selected in the frontend, obviously if I remove a column it will break but I don't want to have to add the column in the django framework even if it is not used. I've read the raw SQL … -
How to prevent Apache web server accepting requests from unknown hosts
I have a Django app running on Elastic Beanstalk which keeps creating redundant sentry error logs when bots make requests with HOST headers not matching my ALLOWED_HOST Django setting. How do configure Elastic Beanstalk to stop Apache accepting any request without my host name (e.g www.example.com) ? There are similar questions on here however they do not explain exactly how to change the Apache configurations during deployment. -
how to deploy a mobile app built with React Native and backend REST Api like Django
I am familiar with ReactJS and recently decided to start building a mobile application with react native. When you are using a front end library like ReactJS + backend framework like Django(Django Rest Framework), assuming they are separated in the infrastructure, you can make them talk to each other reactjs on port 3000 and django on port 8000 using cors-headers then deploy it to a hosting provider like AWS on www.fullstackapp.com as a domain name example where React has a subdomain and django as well but both technology is displayed to the user under a single domain name. As I never deployed a mobile application before, I wonder, what is the way to achieve the same result for a mobile application talking to the backend in production (to be able to deploy that full stack mobile app on Apple Store or Google Play Studio)? Thank you in advance.
