Django 2.2. Instead of my template django uses the standard
I created an authapp application in django. And I registered it in settings and added to the main urls.py: from django.contrib import admin from django.urls import path, include urlpatterns = [ path('admin/', admin.site.urls), path('authapp/', include('authapp.urls', namespace='authapp')), ] In authapp/urls.py I added: from django.contrib.auth import views as auth_views from django.urls import path, reverse_lazy import authapp.views as authapp app_name = 'authapp' urlpatterns = [ path('password_change/', auth_views.PasswordChangeView.as_view(success_url=reverse_lazy('authapp:password_change_done')), name='password_change'), path('password_change/done/', auth_views.PasswordChangeDoneView.as_view(), name='password_change_done'), ] I added my templates to authapp/templates/registration: - password_change_form.html - password_change_done.html But when you click on the link http://127.0.0.1:8000/authapp/password_change/ I get to standart form in the django admin, not my form... What am I doing wrong? -

Use pandas in a django view function to load data from a csv
I want to display time series data in a django application. The data is currently available in a csv-format. The simplest solution that came to my mind was to load the data using pandas in the view function, then perform my desired processing with it and supply the processed data to the HTML template in the context dictionary: def view_function(request): df = pd.read_csv('data/test.csv') # Any further processing of the loaded Dataframe # that returns df_processed context = { 'data': df_processed} return render(request, 'template.html', context) However, since I am new to web development, I wondered if this would be the way how to do it or if there are actually severe problems attached to this solution? If yes, what would be a better way how to do it? -
Unable to generate id for dynamically added table rows - Django dynamic formset
I am trying to implement Django inline formset (with a parent and child scenario) with an option to add rows for the child fields housed in a table. For the purpose I am using Django dynamic formset which is working in so far as the default form layout is concerned as well as adding new rows at runtime. I am able to save and edit data as well, even with the new rows added. However I find, to my dismay, that the id's of the newly added row elements are not generated (when viewed in "view source") - actually there are no reference to the newly added elements at all. Am I missing something or is this the wrong way to go for what I am trying to do, considering that the plugin is pretty "old" and by the looks of it, there has not been much activity on the source page. (I found one user asking whether the plugin may be used with Django 2.0!) The reason I want the id's of individual field elements is, that I need to carry out calculations involving values contained, using jQuery before I submit the form. Without the id's I can not … -

how to pass a Page to a routablepageurl outside of Wagtail
I am new to Wagtail and I am trying to figure out how can I pass the page parameter the routablepageurl requires.

Connect to google sheets API using localhost
I'm using Django. I'm trying to use google sheets API. Well, I'm working on a local environment now and google acceptance OAuth needs to have a certain domain given and localhost doesn't work so I use ngrok. So I filled all those fields with domain and URL that ngrok gave me. I also used my ngrok URL to fill those credential fields. I've downloaded client_secret.json file and I set up all connection and stuff as google recommends on their sheets API docs. But still when I go to my ngrok URL and google connects I see such message that I cannot get rid of: https://accounts.google.com/o/oauth2/auth?response_type=code&client_id=...&redirect_uri=http%3A%2F%2Flocalhost%3A35701%2F&scope=https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fspreadsheets&state=...&access_type=offline The message under that link is: Error: redirect_uri_mismatch The redirect URI in the request, http://localhost:39515/, does not match the ones authorized for the OAuth client. To update the authorized redirect URIs, visit: link to my profile But in my client_secret the redirect_uris is set to: "redirect_uris":["http://something.ngrok.io/plan/create"] At this piot I have absolutely no idea what's going on. -
How can I take input from a text field in a Django page then update a SQL table with the response?
I am working on a site that will be used to clean up inactive Tableau workbooks. Logging into this site will allow my users to see their old workbooks and decide which ones to keep. This is going to be accomplished by taking some simple text input from an HTML page, K for keep | D for delete. The response from the user will then be stored as a Python variable that will go into an if then statement. The if then statement will basically update each row in SQL, adding either K or D to a column called "Marked_for_Deletion". From there, a stored procedure will run, check that column, and delete all things marked with a D. Is this feasible? If so, how would I go about pulling that input and making sure it gets added to the right column/row? If not, can you offer any suggestions on a substitute method I can use? Thanks! -

Executing JavaScript functions in Django Templates
I have a Django App that, from a template feed.html calls different templates for different elements in the data base. The idea is to use a JavaScript script to visualize each one of these elements, the problem is that it just show the last one of them (the last element in this page). The script is this one: function showPiece(targ, piece){ window.onload = function(){ Lily.ready({ target: targ, // target div id file: 'files', // file input id path: '../../static/js/src', // path to source directory from current html file }); }; window.onload = function(){ var madeleine = new Madeleine({ target: targ, // target div id data: piece, path: '../../static/js/src', // path to source directory from current html file }); }; }; I am calling the script from the feed.html file. <script type="text/javascript" charset="utf-8"> var url_objetivo = '{{ piece.file.url }}' var id_objetivo = "id-" + {{ piece.id}} showPiece(id_objetivo, url_objetivo) </script> How can I force it to display the information for every element? -
Database table for custom categories that extends basic categories
I want to make Django app that helps user track his income/expenses. I'd like to store categories in a database, and I'd like to have a table with some basic categories like 'shopping', 'eating out', 'sport' and so one, but I also want to give a user a change to add his own, custom categories. I am wondering what the best approach for this case would be. I was thinking of creating a 'BASIC CATEGORIES' table, and then 'USER CATEGORIES' with user_id, and a name of category. And then in for example 'EXPENSES' table I would have: user_id, amount, basic_category_id, user_category_id, where one of 'category_id' would have to be null. Is my approach correct? -

Django DateInput() widget not working in ModelForm
I'm making a user login form with a CustomUser model derived from AbstractUser, with one extra field: date_of_birth. I use CreateView to generate the form. All fields show up, the password field uses the password widget as expected (showing dots instead of characters), but the date field does not (plain character field with no formatting or calendar). What am I overlooking? models.py: from django.urls import reverse from django.contrib.auth.models import AbstractUser # Create your models here. class CustomUser(AbstractUser): date_of_birth = models.DateField(verbose_name="Date of Birth", blank=True, null=True) def get_absolute_url(self): return reverse('index') def __str__(self): return self.username forms.py: from .models import CustomUser class CustomUserForm(forms.ModelForm): class Meta: model = CustomUser fields = ["username", "password", "first_name", "last_name", "email", "date_of_birth"] widgets = { "password": forms.PasswordInput(), "date_of_birth": forms.DateInput() } views.py: from django.views.generic.edit import CreateView from .models import CustomUser from .forms import CustomUserForm # Create your views here. def index(request): return HttpResponse("Hello, world") class CustomUserCreate(CreateView): model = CustomUser form_class = CustomUserForm -

Linking to AWS S3 direct image uploads in Django templates
I'm using AWS S3 buckets for my images in my Django project through django-storages. It's pretty clear how to show an image in a template that has been uploaded through a model ImageField. Just do e.g. <img src="{{ model.image.url }}"> What if, however, I upload an image on S3 directly (e.g. for the website logo) and want to show it in a template? Any better way to just hardcoding the absolute Amazon S3 path: <img src="https://myapp.s3.amazonaws.com/home/logo.png"> ? Some way I can use just the relative "/home/logo.png" without hardcoding the amazonaws subdomain? -
