Collection, storage, and visualization of third party data using Django?
This question is based on a previous one I recently asked. I have tried to make this question as detailed as possible. My goal: I am creating a web app that allows for exploratory analysis of ocean buoys. User selects a buoy and some graphing options (e.g., monthly averages, filters to swell size, etc.) and a graph is made showing the resulting data for that buoy. Approach: User identifies a buoy through a web form or some type of selector and chooses options for the plot (e.g., monthly averages across all time). Data is queried for the selected buoy. Data is converted into a pandas dataframe of buoy time series data. Pandas processes the data based on the option selected by the user (e.g., calculates monthly averages). Plotly creates a chart The chart is sent to the templates.py in the views.py file, and the chart is rendered on the webpage. My problem: Collecting the data is difficult. The archived data for all buoys exists on NOAA's NDBC webpage and there is no simple API for accessing this archived data. Rather, it is stored on multiple pages in multiple CSVs. Thankfully, some open source code already exists for accessing this data. … -
Django templates: using include to pass a form template; how to write the form?
I simply would like to create a form, throw it in a template, and use the include keyword to include it in my home.html file. What am I doing wrong ? # forms.py class OrderForm(forms.Form): from_email = forms.EmailField(required=True) subject = forms.CharField(required=True) message = forms.CharField(widget=forms.Textarea, required=True) # views.py def orderView(request): template = 'orders.html' if request.method == 'GET': form = OrderForm() else: form = OrderForm(request.POST) if form.is_valid(): subject = form.cleaned_data['subject'] from_email = form.cleaned_data['from_email'] message = form.cleaned_data['message'] try: send_mail(subject, message, from_email, ['admin@example.com'] except BadHeaderError: return HttpResponse('Invalid header found.') return redirect('success') return render(request, 'orders.html', {'form': form}) <!-- templates/orders.html --> <form method="post"> {% csrf_token %} {% form.as_p %} <button type="submit" class="btn btn-primary">Send</button> </form> <!-- templates/home.html --> ... <div class="orders"> {% include 'orders.html' %} </div> ... -

Importing excel data to django database in parent child format
My requirement is to save the excel data in the django DB using import which I could do using below code. But next I want to save the data in a one to many relationship. ie. I want a unique key to be generated and saved in Main_page model and corresponding to that my uploaded excel file data should share the same primary key in the Upload model. For eg. If the main_page has id 1, so for my complete excel data uploaded i want the data to share the same key. What changes or any link should i learn or go through. I am stuck since last few days but no luck. Thanks in advance models.py class Upload(models.Model): sheet_key = models.ForeignKey(Main_page) Student_Name = models.CharField(max_length=100) Total_Marks = models.IntegerField() Marks_Scored = models.IntegerField() class Main_page(models.Model): sheet_key = models.AutoField(primary_key=True) date = models.DateField() views.py class UploadFileForm(forms.Form): file = forms.FileField() def import_data(request): if request.method == "POST": form = UploadFileForm(request.POST, request.FILES) # Check if the form is valid if form.is_valid(): request.FILES['file'].save_to_database( # Save the file data to the database name_columns_by_row=1, model=Upload, mapdict=['Student_Name', 'Total_Marks', 'Marks_Scored', 'Status', 'Date', 'College_Name', 'Phone Number']) # Columns to be mapped return HttpResponse("OK") else: # If the form has errors show the error. … -

Tags containing spaces surrounded by quotes
I'm writing a simple notetaking app, and I have implemented tags on my notes. I'm using django-taggit for server-side implementation and bootstrap4 tag input plugin for front-end. I'm having an issue with something adding quotes around my tags that contain spaces and I cannot determine what, whether it is django-taggit or the bootstrap plugin. This is a pic of how my UpdateView looks like: so when I'm adding tags that contain spaces, they're added as they should (no quotes), however when I come back later to them (say, in UpdateView), the quotes are displayed. I have tried to print the tag in Django shell but I can't see the quotes that are being added: >>> Note.objects.get(pk=1).tags.all()[2].__str__() 'hello world' So I'm thinking the issue must be in the bootstrap plugin. How can I overcome the issue? There's quite a bit of code to this so I wasn't sure what pieces to include, if you need something, just let me know. Thanks. -

Downloaded compressed data (`gz`) from django server using ajax is inflated and broken
I'm trying to download a .gz file from a django server (Python 3.7) using Ajax request. This is the minimal django view function and Ajax function to request download on client, compress a folder and send it (server) and receive the data on the client: from pathlib import Path def downloadfile(request): folder = Path().home().joinpath('workspace') tar_path = Path().home().joinpath('workspace.gz") tar = tarfile.open(tar_path.as_posix(), "w:gz") tar.add(folder.as_posix(), arcname='workspace') tar.close() try: with open(tar_path.as_posix(), 'rb') as f: file_data = f.read() response = HttpResponse(file_data, content_type='application/gzip') response['Content-Disposition'] = 'attachment; filename="workspace.gz"' except IOError: response = HttpResponse('File not exist') return response This is the Ajax function on the client side: $(function () { $('#downloadfile').submit(function () { $.ajax({ type: 'POST', url: 'downloadfile', success: function(response){ download(response,'workspace.gz', 'application/gzip'); } }); return false; }); }); function download(content, filename, contentType) { var a = document.createElement('a'); var blob = new Blob([content], {'type':contentType}); a.href = window.URL.createObjectURL(blob); a.download = filename; a.click(); } A sample gzipped folder that is 36.5 KB will be inflated to 66.1 KB when downloaded and it clearly can't be extracted. What I know: The file is healthy and extractable on server side. The data is transferred and downloaded on the client but inflated and broken.

django-import-export - Importing ManyToMany from JSON file
I'm trying to import a JSON file that contains a many-to-many relationship but am hitting some problems. This is my code: book.json { "title": "The Lord of the Rings", "categories": [ "Fantasy", "Action", "Adventure" ] } models.py from django.db import models class Category(models.Model): guid = models.CharField(max_length=36) display_name = models.CharField(max_length=50) description = models.TextField() def __str__(self): return self.display_name class Book(models.Model): title = models.CharField(max_length=200) categories = models.ManyToManyField(Category) def __str__(self): return self.title resources.py from import_export import resources from import_export.fields import Field from import_export.widgets import ManyToManyWidget from .models import Book, Category class BookResource(resources.ModelResource): categories = Field(widget=ManyToManyWidget(Category)) class Meta: model = Book import_id_fields = ('title',) importer.py from resources import BookResource from models import Book with open("book.json", 'r') as f: book = '[' + f.read() + ']' result = BookResource().import_data(tablib.Dataset().load(book), raise_errors=True, dry_run=True) This seems to run through without errors, and adds the new book to the database. The problem is that it doesn't create a new entry in the book_categories table (PostgreSQL). I think I'm definitely missing a step somewhere because I haven't defined how to find the correct category database entries, given I the list of display_name strings. Am I on the right track here? -
How long did it take you to integrate Stripe (Django)?
This is a fairly general question. I'm integrating Stripe to my website to handle subscriptions / upgrades. I've never done it before, and it has taken me about 1.5 days to integrate it into my Django-based website, including all the templates, upgrade/downgrade pages and changing my User models in Django. My main bottlenecks have been JavaScript/jQuery as I have just no experience with it, and obviously figuring out the API, although I must say the documentation was excellent. How long should it have taken me? How long did it take you, for those who've done it before? Just asking out of interest/curiosity. Thanks! -
Custom Django Rest Framework authentication validating when 'None' is returned
I am working on implementing JWT for authentication. Of course, this means I have to do some custom authentication. According to the docs, "If authentication is not attempted, return None." So, I have code that checks for an authorization header (where the JWT resides) and returning "None" if an authorization header does not exist. This means that authorization was not attempted (and according to the docs) I should return None. However, Django is saying that the user is authorized: Root/authentication/TokenAuthentication/TokenAuthentication from rest_framework import status from django.http import HttpResponse from rest_framework.authentication import get_authorization_header, BaseAuthentication from django.contrib.auth.models import User import jwt, json class TokenAuthentication(BaseAuthentication): def authenticate(self, request): auth = get_authorization_header(request).split() if not auth: return None Login.py @api_view(['POST']) def login_view(request): if not request.data: return Response({'Error': "Please provide username/password"}, status="400") username = request.data['username'] password = request.data['password'] try: user = User.objects.get(username=username) if not user.check_password(password): raise User.DoesNotExist except User.DoesNotExist: # if user not found or password is wrong return Response({'Error': "Invalid username/password"}, status="400") if user.is_authenticated: print("user is authenticated") # THIS GETS PRINTED else: print("User is not authenticated") Settings.py REST_FRAMEWORK = { 'DEFAULT_AUTHENTICATION_CLASSES': [ #'rest_framework.authentication.BasicAuthentication', 'Root.authentication.TokenAuthentication.TokenAuthentication' ] } The line if user.is_authenticated: print("user is authenticated") Is running everytime when None is being returned.

Query Django JSONFields that are a list of dictionaries
Given a Django JSONField that is structured as a list of dictionaries: # JSONField "materials" on MyModel: [ {"some_id": 123, "someprop": "foo"}, {"some_id": 456, "someprop": "bar"}, {"some_id": 789, "someprop": "baz"}, ] and given a list of values to look for: myids = [123, 789] I want to query for all MyModel instances that have a matching some_id anywhere in those lists of dictionaries. I can do this to search in dictionaries one at a time: # Search inside the third dictionary in each list: MyModel.objects.filter(materials__2__some_id__in=myids) But I can't seem to construct a query to search in all dictionaries at once. Is this possible? -
Programatically create nested plugins to display data on Django CMS
I have been trying to retrieve multiple arrays of data from firebase, turn the data into multiple plugins and then pass those into one of my templates. I have been trying to find information on the docs about it but all I can find is this.

Adding a separate field to a form in django template in view
So this is what I want to do: I have a model, that I created a form to fill using forms.Form.

Django - How to store and render a Pandas dataframe/CSV for each model entry?
I have a model that represents a single patient. It stores information such as the patient_name (CharField), weight (IntegerField), height (IntegerField) etc. I extended the save method save(self, *args, **kwargs) to perform a series of calculations/functions (e.g. calculate BMI) to save back to the model. For the extended save() method, it also runs a function that calculates weekly weight loss goals in pandas and saves to CSV (named by patient_name) in a media folder. I'm trying to figure out the best way to display that CSV data back for each patient. Currently, I'm using the DetailView CBV to serve up a detail page for each patient with their new computed model fields (e.g. <p>{{ object.patient_name }}'s calculated BMI is {{ object.bmi }}</p>) There are three ideas I have but I'm not sure if they will work or how to implement it. 1 - I could generate an HTML table instead of CSV, is there a way to render custom HTML snippets from a media folder based on a trait of the model or primarykey id {% media|object.patient_name %}? 2 - I could try to save the pd.DataFrame, CSV (or the string text representation of an HTML table) to a new … -

Django template iframe card information
I have a payment gateway that returns redirect url for getting card information when supplied with right authentication credentials. Now I am comparing two possibilities for displaying this url to users: Redirecting user to given url Loading content of redirect url in django template as iframe From design and end user's aspects, it is obviously better to include content as iframe. However, I suppose that there is security concerns in this option. Is it secure to load such content as iframe in django template? Which measures should be taken to avoid possible security problems? Note: Payment processor didn't provide any clause about iframe in its documentation. -
Display Django Field properties, such as min_value and max_value, in the Template
I have a Django Form with an IntegerField. I give the IntegerField a min_value and a max_value. I would like to DISPLAY that min_value and max_value for the user, so I'm trying to include it in the template next to the input field itself. Seems like this should not be so hard, but it isn't working. :-( Below, the "print" statement in views.py works just fine. So I know that one can access the min_value from the field with just ".min_value". But the min_value in the template does not show up in the browser. Thoughts anyone?? In forms.py class MyForm(forms.Form): somenumber = forms.IntegerField(min_value=0, max_value=12) In views.py: form = forms.MyForm() print(form.fields['somenumber'].min_value) ... context = {'form':form} ... In template: {{ form.somenumber.min_value }}
