Django/React App: How to have both Django URLS (for the api to send data) and React URLS (to render my components) in my web app, compatibly
I just added this to the urls.py in my react folder: re_path(r'^(?:.*)/?$', views.index), after following this stackoverflow post: react routing and django url conflict. My error in the dev tools is: Unknown_URL_Scheme However, in my situation, this creates problems. My method of sending JSONs to my react is through the url: "api/leads," which is now inaccessible. How do I produce a way for my react urls to exist in harmony with my django urls? Attached are my django urls.py, react--> App.js, urls.py, views.py, index.html, and DataFetching.py (where you will be able to see how I send the data from my api). Django: urls.py from django.urls import path from . import views urlpatterns = [ path('api/lead/', views.LeadListCreate.as_view()), ] Django Project: urls.py from django.contrib import admin from django.urls import path, include, re_path urlpatterns = [ path('admin/', admin.site.urls), path('', include('leads.urls')), path('', include('frontend.urls')), ] React--> urls.py from django.urls import path, re_path from . import views urlpatterns = [ #path('', views.index), re_path(r'^(?:.*)/?$', views.index), ] By the way, I tried to look at the documentation for urls(r^...) and it wouldn't tell me how to import it, but instead basically said that urls is basically the same as re_path; this may be the problem, nonetheless, I would … -
Return updated HTML table values into Views.Py
Hi I have an html table that has values that is originally pulled from a database. They are editable and if the user updates the value, I want to be able return the updated values to Views.py and then from there save the updated value back into the database. For example, I have the table below: <table> <tr> <th>A</th> <th>B</th> <th>C</th> <th>D</th> <th>E</th> <th>F</th> </tr> {% for x in VAR %} <tr> <td>Yes</td> <td>{{ x }}</td> <td><div contenteditable>{{ x.a }}</div></td> <td><div contenteditable>{{ x.b}}</div></td> <td><div contenteditable>{{ x.c}}</div></td> </tr> {% endfor %} </table> If they update x.a for example, I want to return the new value to Views. When I try a POST request, I return a blank value / empty list. How do I return the updated values into my Views.py? -
How do I check if user exists or not and add or update the database in DRF according to that?
I am writing an app in which the user inputs either their email or number to continue. If the user only writes one of those, I need to check if either the email or number belong to an existing user so I can use that user. If the user writes both things, I need to check if the user exists (if it does, I use it, if not I create it). If the user exists with only email or number, I need to update the other field that does not match. I wrote something but I'm not sure how to go on, I'm pretty new at this. This is what I have so far in my serializer: class OrderSerializer(serializers.ModelSerializer): class Meta: model = Order fields = '__all__' def checkuser(self, email, number): if order['email'] or order['number'] in User: return User elif order['email'] or order['number'] not in User: pass elif order['email'] and order['number']: if not in User: UserSerializer() elif order['email'] or order['number']: if User.objects.filter(**validated_data).exists(): return User.objects.create(**validated_data) -
Multiple autocomplete-light dropdowns in django template
I am building a web application that requires searching for a specific user record by entering one of two attributes: first name OR last name. Eventually there will be two more search attributes, but currently having problems with having two autocomplete-light drop-downs in the same template. The problem is that only the second input is working as expected. Below are the relevant code sections (with irrelevant code removed). This approach is not "DRY" but my priority is to have a working implementation before optimization/refactoring. forms.py class StudentChoiceFieldLN(forms.Form): students = forms.ModelChoiceField( queryset=Student.objects.all().order_by("last_name"), widget=autocomplete.ModelSelect2(url='student-ln-autocomplete'), ) def __init__(self, *args, **kwargs): super(StudentChoiceField, self).__init__(*args, **kwargs) # without the next line label_from_instance does NOT work self.fields['students'].queryset = Student.objects.all().order_by("last_name") self.fields['students'].label_from_instance = lambda obj: "%s %s" % (obj.last_name, obj.first_name) class StudentChoiceFieldFN(forms.Form): students = forms.ModelChoiceField( queryset=Student.objects.all().order_by("first_name"), widget=autocomplete.ModelSelect2(url='student-fn-autocomplete'), ) def __init__(self, *args, **kwargs): super(StudentChoiceFieldFN, self).__init__(*args, **kwargs) # without the next line label_from_instance does NOT work self.fields['students'].queryset = Student.objects.all().order_by("first_name") self.fields['students'].label_from_instance = lambda obj: "%s %s" % (obj.last_name, obj.first_name) views.py class StudentLNAutoComplete(autocomplete.Select2QuerySetView): def get_queryset(self): qs = Student.objects.all() if self.q: qs = qs.filter(last_name__istartswith=self.q) return qs class StudentFNAutoComplete(autocomplete.Select2QuerySetView): def get_queryset(self): qs = Student.objects.all() if self.q: qs = qs.filter(first_name__istartswith=self.q) return qs def index(request): students_choice_ln = StudentChoiceFieldLN() students_choice_fn = StudentChoiceFieldFN() context = { 'students_choice_ln': students_choice_ln, 'students_choice_fn': … -

Django Server Wont Relaunch after change
I've been experimenting with both the django and django rest framework. My projects all used to be working fine, but the other day I had to hard reset my macbook. Since then whenever I go open an old project, or even make a new one whenever I make changes in my vscode project folder, my server does not update and relaunch. Also when I run 'python manage.py migrate' it says there are no migrations to be made, even though I have created new models. The only time python manage.py migrate' had worked was straight after using the 'pip install django'. (Just an fyi, but I completely remade a project I had done previously (a follow through on youtube), when I had first made the project it worked perfectly, but when remaking it the server does not relaunch after changes nor do migrations work) -
PyMongo + Django: MongoClient constructed in settings returning no data
My Django app constructs a MongoClient in the settings file, and this works in local environments. mySettings.py: # mysettings.py MONGO_HOST = os.environ.get('MONGO_HOST') MONGO_PORT = int(os.environ.get('MONGO_PORT')) MONGO_DATABASE = os.environ.get('MONGO_DATABASE') MONGO_USERNAME=os.environ.get('MONGO_USERNAME') MONGO_PASSWORD=os.environ.get('MONGO_PASSWORD') MONGO_CLIENT = MongoClient( host=MONGO_HOST, port=MONGO_PORT, username=MONGO_USERNAME, authSource=MONGO_DATABASE, password=MONGO_PASSWORD, connect=True ) When I use this instance on a local workstation, it works as expected. However, when I use it in a Kubernetes pod, queries like the ones below return zero/empty instead of the proper count/data. #mybrokenscript.py client = settings.MONGO_CLIENT database = client["mydatabase"] collection = database.get_collection('myCollection') print("Count: ", collection.count()) # returns 0, though the collection contains data for doc in collection.find(): # we never get here When I construct a local MongoClient with the same values, it works as expected. #myworkingscript.py client = MongoClient( host=settings.MONGO_HOST, port=settings.MONGO_PORT, username=settings.MONGO_USERNAME, authSource=settings.MONGO_DATABASE, password=settings.MONGO_PASSWORD ) database = client["myDatabase"] collection = database.get_collection('myCollection') print("Count: ", collection.count()) # returns the right number for doc in collection.find(): # works as expected To be clear, the two scripts above generate different results. In the first, Count is 0. In the second, Count is the number of documents in the collection. Any idea what could be happening? Python 3.6.8 Mongo 4.4.4 pymongo 3.7.1 Django 3.1 -
Django Storing Images Locally And Remotely
I have built an image sharing website on django in which i'm storing my thumbnails images on server and original images on object storage. The problem i'm facing is that i'm able to upload the images onto the server and object storage but facing issues to download from object from object storage as my media_root is set at the location of the server. This is my settings.py code : # Base url to serve media files MEDIA_URL = '/media/' # Path where media is stored MEDIA_ROOT = os.path.join(BASE_DIR, 'media/') This is my download function code : def download(request,id): previous_url = request.META.get('HTTP_REFERER') if request.method == 'POST': recaptcha_response = request.POST.get('g-recaptcha-response') data = { 'secret': settings.GOOGLE_RECAPTCHA_SECRET_KEY, 'response': recaptcha_response } r = requests.post('https://www.google.com/recaptcha/api/siteverify', data=data) result = r.json() ''' End reCAPTCHA validation ''' if result['success']: image = Image.objects.get(id=id) file_name = os.path.basename(image.image.name) file_path = image.image.name fl = storage.open(file_path, "rb") content_type = mimetypes.guess_type(file_path)[0] response = HttpResponse(fl, content_type=content_type) response['Content-Disposition'] = 'attachment; filename=%s' % smart_str(file_name) response['X-Sendfile'] = smart_str(file_path) return response else: messages.error(request, 'Invalid reCAPTCHA.

How can I make a field case insensitive and unique only?
I'm trying to add object to my models that are unique and case insensitive so if I add 'car' first and then I try to add 'cAr' it should return an error. I don't know how to that, though. How can I make this happen? This is the model: class Food(models.Model): name = models.CharField(max_length=100, unique=True) def __str__(self): return self.name This is the serializer: class FoodSerializer(serializers.ModelSerializer): class Meta: model = Food fields = '__all__' -
Django rest-framework ListCreateAPIView doesn't return the full path for the file
I just started using Django rest-framework, and I wanted the JSON response to return the URL for the file stored in the server, I used generics.ListCreateAPIView class class PeopleList(generics.ListCreateAPIView): queryset = People.objects.all().order_by('registration_time') serializer_class = PeopleSerializer and it worked actually! it returned a full path clickable URL: { "id": 1, ... "profile": "http://127.0.0.1:8000/media/profile_image/IMG_20190826_105834_vwKLf10.jpg", ... }, But then I had to use the list function because I needed the request object, now the response only contains the path without the domain: { "id": 1, ... "profile": "/media/profile_image/IMG_20190826_105834_vwKLf10.jpg", ... }, so the question is, How can I return the whole URL? -
How to tell serializer field is in nested dict?
I have the following models: class Holding(models.Model): ticker = models.CharField(max_length=32) class Fund(models.Model): name = models.CharField(max_length=32) holdings = models.ManyToManyField(Holding) JSON looks like this: { "name": "iShares Index Fund" "holdings":[ { "holding": { "ticker": "AAPL" }, { "holding": { "ticker": "AMZN" } ] } My serializers looks like this: class HoldingSerializer(serializers.ModelSerializer): class Meta: model = Holding fields = '__all__' class FundSerializer(serializers.ModelSerializer): holdings = HoldingSerializer(many=True) class Meta: model = Fund fields = '__all__' however it doesn't work because holding is nested How do I tell the HoldingSerializer that the ticker is inside a nested object? I've tried class HoldingSerializer(serializers.ModelSerializer): ticker = serializers.CharField(source='holding.ticker') class Meta: model = Holding fields = '__all__' but I dont think source is used to specify the source in the json; it is used to specify the source from the django models, is that correct? however I still get the error {'holdings': [ { 'ticker': [ErrorDetail(string='This field is required.', code='required')], }, { 'ticker': [ErrorDetail(string='This field is required.', code='required')] }] } -
Adding array into excel using openpyxl (formatting issue)
I am using "openpyxl" to put an array into an excel file for users to download on a django site. The data goes into the excel fine using the following loop: for row_num, row in enumerate(matrix, 3): for col_num, item in enumerate(row, col_start - 12): ws.cell(column=col_num, row=row_num, value=item) wb.save(excel_file_path_from_db) My problem is that when the data enters the excel is is not in number format. I think it could be because i am getting my atix values from a user input via: matrix = ast.literal_eval(list(request.GET)[0]) print(matrix) Any ideas how I can make my matrix come into the excel file in number format? -

Django | Adding/changing code in 3rd party packages with monkey patching
(+/- 3 months experience with Django) I'm using the django-newsletter package to create and send newsletters to subscribers on my website. It uses a message.html template for which the context is added in the Submission model: class Submission(models.Model): # Some irrelevant code, only showing the send_message method below: def send_message(self, subscription): variable_dict = { 'subscription': subscription, 'site': Site.objects.get_current(), 'submission': self, 'message': self.message, 'newsletter': self.newsletter, 'date': self.publish_date, 'STATIC_URL': settings.STATIC_URL, 'MEDIA_URL': settings.MEDIA_URL } unescaped_context = get_context(variable_dict, autoescape=False) subject = self.message.subject_template.render( unescaped_context).strip() text = self.message.text_template.render(unescaped_context) message = EmailMultiAlternatives( subject, text, from_email=self.newsletter.get_sender(), to=[subscription.get_recipient()], headers=self.extra_headers, ) if self.message.html_template: escaped_context = get_context(variable_dict) message.attach_alternative( self.message.html_template.render(escaped_context), "text/html" ) # some more code irrelevant to the question message.send() Essentially upon Submitting the newsletter, the context is added in variable_dict in the Submission.send_message method. In order to add more Personalization possibilities I would like to add my own context variables to this. From what I understand is that it's best to use monkey patching to achieve this, but I am not able to access the variable_dict from outside the method itself. Below is my monkey patch code: ## Monkey Patching ## # monkey_patches.py DJANGO_NEWSLETTER_CONTEXT_PATCH = True # adds context to Submission def monkey_patch(): if DJANGO_NEWSLETTER_CONTEXT_PATCH: from newsletter.models import Submission old_send_message … -

Add forms to a Django formset dynamically using htmx?
There are several writeups on how to use javascript to add forms dynamically to a Django formset. For example this or this. I just learned about htmx. How can I add forms dynamically to a Django formset using htmx instead of hand-coded javascript? I thought maybe I could use click-to-load, but it seems odd to call back to the server to get an empty row. Maybe this just isn't an htmx thing. -

Django app accessing WooCommerce database - how to follow coupon to order relationship in the template
I am developing a Django application which provides read-only access to a WordPress WooCommerce database. I have created a view where I would like to show a list of WooCommerce coupons and any related order data where the coupon was used. The relation between a coupon and the order it was used in is in the table WpWcOrderCouponLookup, and I am passing the contents of this table by adding it as an additional parameter in get_context_data. What I can't figure out is how to access a specific record in the WpWcOrderCouponLookup structure from inside the template. I'll include my code below. Since I am using an existing Wordpress database, my models came from an inspectdb command, and I modified the output to include what I hope are the correct foreign key relations. This is the relevant model code: class WpPosts(models.Model): id = models.BigAutoField(db_column='ID', primary_key=True) # Field name made lowercase. post_author = models.PositiveBigIntegerField() post_date = models.DateTimeField() post_date_gmt = models.DateTimeField() post_content = models.TextField() post_title = models.TextField() post_excerpt = models.TextField() post_status = models.CharField(max_length=20) comment_status = models.CharField(max_length=20) ping_status = models.CharField(max_length=20) post_password = models.CharField(max_length=255) post_name = models.CharField(max_length=200) to_ping = models.TextField() pinged = models.TextField() post_modified = models.DateTimeField() post_modified_gmt = models.DateTimeField() post_content_filtered = models.TextField() post_parent = models.PositiveBigIntegerField() … -
Cannot run django migrations
I have a mysql database. On this database, I have tried to create an account and then grant that account permissions to create a test database and standard database. To look at permissions, I use the following: SHOW GRANTS FOR 'broker_admin'@'localhost'; This then produces an output similar to: 'GRANT USAGE ON *.* TO 'broker_admin'@'localhost' 'GRANT ALL PRIVILEGES ON `dbbrokerdata`.`dbbrokerdata` TO 'broker_admin'@'localhost' 'GRANT ALL PRIVILEGES ON `test_dbbrokerdata`.`test_dbbrokerdata` TO 'broker_admin'@'localhost' When I try to run the django app that uses this database, I get the following errors: django.db.utils.OperationalError: (1142, "CREATE command denied to user 'broker_admin'@'localhost' for table 'django_migrations'") django.db.migrations.exceptions.MigrationSchemaMissing: Unable to create the django_migrations table ((1142, "CREATE command denied to user 'broker_admin'@'localhost' for table 'django_migrations'")) Watching for file changes with StatReloader Performing system checks...

django-rest-framework "This field is required" on POST
Whenever I POST to my django-rest-framework (DRF) endpoints, I keep receiving a "HTTP 400 Bad Request" {"offeror_organization":["This field is required."]} response. But, given the curl example below, I'm clearly specifying a value. This happens regardless of the Content-Type (application/json, application/x-www-form-urlencoded, multipart/form-data). The only time it works is when I submit using the "HTML form" (vs. the "Raw Data") tab on the DRF web interface. There's a few similar SO posts (like this and this), but none of the solutions seem to be working for me. Model: class OrganizationManager(models.Manager): def get_by_natural_key(self, offeror_organization): return self.get(offeror_organization=offeror_organization) class Organization(models.Model): idorganization = models.AutoField(primary_key=True) offeror_organization = models.CharField(max_length=250, null=False, blank=False, verbose_name='Offeror Organization') created_at = models.DateTimeField(auto_now_add=True, null=False) updated_at = models.DateTimeField(auto_now=True, null=False) objects = OrganizationManager() def natural_key(self): return "%s" % (self.offeror_organization) def __str__(self): return self.offeror_organization Serializer: class OrganizationSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = Organization fields = ['offeror_organization'] # I've tried both with and without a create function def create(self, validated_data): organization_data = validated_data.pop('offeror_organization', None) if organization_data: organization = Organization.objects.get_or_create(**organization_data)[0] validated_data['offeror_organization'] = organization Curl Command: curl -X POST -H 'Content-Type: application/json' -d '{"offeror_organization":"Test2"}' 10.101.10.228:29000/webapp/api/organization/ -
Problem while building path to page with detailed news view
I want it to output all the news when I click on one url, but I can also specify an optional parametric, which, if it exists, will only output the specific news. I can do it. But my navbar in header complains about it. my url: url(r'^news/(?P<year>)',FindNewsView.as_view(), name="news"), error: NoReverseMatch at /news/ Reverse for 'news' with no arguments not found. 1 pattern(s) tried: ['news/(?P<year>)'] <div class="dropdown-menu"> <a class="dropdown-item" href="{% url 'news' %}">Новости</a> </div> How do I correct this error? So if I comment out this line, everything will work. I will receive all news or specific news. -
Images and CSS are not being loaded, requires random amount of refresh to load
The problem My company's Django project, running with Nginx and gunicorn, started presenting this issue in the development server. Basically, if I access the app with empty cache, styling files and images are not being loaded at all. Chrome throws the error net::ERR_HTTP2_PROTOCOL_ERROR 200, Safari throws kCFErrorDomainCFNetwork error 303, and Firefox does not throw and error (in fact it gives a 200 for both images and css) but says Stylesheet could not be loaded. However, if I refresh many times the browsers (it could be two times as well as twenty, or more) the images and styles are loaded correctly (one at a time). There are times where some of the images load on first GET request, but it is not a guarantee that those images will be loaded again if I empty cache and refresh. Same setup, different result The funny thing is that on the production server we DO NOT have this problem while both Django settings are the same. The ONLY difference is which DB the apps are pointing to. Both environments have DEBUG set to True. I don't know why prod server has DEBUG set to True, but since it is an app to be used … -
