Django REST framework ModelSetView POST not allowed
I am trying to learn how to use Django REST framework. I want to make a very simple API using ModelViewSet. I've followed the docs but it's not exactly clear to me if ModelViewSet provides an automatic mapping from its create to POST when doing router.register(r"polls", QuestionViewSet, basename="polls") I keep trying my endpoint: curl --location --request POST 'http://localhost:8005/polls/' \ --header 'Content-Type: application/json' \ --data-raw '{ "question_text": "how it do", "pub_date": "01-01-2021" }' But it returns: {"detail":"Method \"POST\" not allowed."} Models: class Question(models.Model): question_text = models.CharField(max_length=200) pub_date = models.DateTimeField('date published') class Choice(models.Model): question = models.ForeignKey(Question, on_delete=models.CASCADE) choice_text = models.CharField(max_length=200) votes = models.IntegerField(default=0) Serailizer and ModelViewSet: class QuestionSerializer(serializers.ModelSerializer): class Meta: model = Question fields = ["id", "question_text", "pub_date"] class QuestionViewSet(viewsets.ModelViewSet): queryset = Question.objects.all() serializer_class = QuestionSerializer() Routers: from django.conf.urls import re_path, url, include from django.urls import path from rest_framework import routers from .question import QuestionViewSet router = routers.DefaultRouter() router.register(r"polls", QuestionViewSet, basename="polls") urlpatterns = router.urls -
name 'InMemoryUploadedFile' is not defined in django model?
So basically I have a django model which has a filefield. I'd like to resize images that get submitted and I have this code here to do that def save(self, *args, **kwargs): img = Image.open(self.media) output = BytesIO() original_width, original_height = img.size aspect_ratio = round(original_width / original_height) desired_height = 100 desired_width = desired_height * aspect_ratio img = img.resize((desired_width, desired_height)) img.save(output, format='JPEG', quality=90) output.seek(0) self.image = InMemoryUploadedFile(output, 'ImageField', "%s.jpg" % self.image.name.split('.')[0], 'image/jpeg', sys.getsizeof(output), None) super(Post, self).save(*args, **kwargs) The error im getting is "name 'InMemoryUploadedFile' is not defined". How do I fix this? Also a side question. The model also takes in videos. How would I resize a video? This is just a side question the InMemoryUploaded is the main question. Thank you! -
How can I make my graphene-python API respond faster?
I've built a python/daphne/django/graphene server, and did everything I could to optimize my queries -- cached db queries in Redis so that they are basically free, and eventually came to find that even with a very small graph schema I still see a >200ms overhead inside of graphql-core, evidently parsing my query. I come from a REST-api-centric worldview, and in this case the stack decisions were out of my hands. I'm just trying to make it work. Queries that a normal django view should return in ~20ms still take ~250ms. Given that I'm consistently sending the same few queries, it would be fantastic to skip the repetitive parsing of the same query over and over again. So, I'm curious what the Python graphql people do, to make their service perform, and to begin with, I'd like to know: Should I just expect to live with that query overhead? Can I improve by doing something like switching from Daphne to Uvicorn, or even mod_wsgi (am not doing any async stuff) Is there any way to circumvent repeated parsing of the same query? thanks for your time and assistance. -
Cannot saving form in django
So i'm using the auth.models.user to create user model and by default it's passing ('first_name', 'last_name', 'username', 'email', 'password1', 'password2'). and the forms.py: class UserSignUpForm(UserCreationForm): class Meta: fields = ('first_name','last_name','username', 'email', 'password1', 'password2') model = user def __init__(self,*args,**kwargs): super().__init__(*args,**kwargs) self.fields['username'].label = 'Username' self.fields['email'].label = "Email Address" i try to allowing user to edit their personal information from all avaliable fields in UserSignUpForm, except the password fields. so i created this views.py (function based view): def edit_account(request): user = request.user form = UserSignUpForm(instance=user) if request.method == 'POST': form = UserSignUpForm(request.POST, instance=user,) if form.is_valid(): form = UserSignUpForm(instance=user) form.save() messages.success(request, 'Your account has been updated.') return redirect('/dashboard/profile/') context = {'editform':form} return render(request, 'accounts/updateaccounts.html', context) tried submit the specific field form like{{editform.first_name}} after passsing it in the html page (because i dont want to user be able edit their password) but it still not update/saving the new user data. is there any method so it can be save? thanks -
Pandas & Jango - How to create a DataFrame filter from multiple user inputs without using string executable
I am building a website where users can graph data in a dataframe and apply filters to this data to only plot information they are interested in, as shown below Right now I am having trouble figuring out a way to take the filters a user inputs in the fields above and using those inputs to filter the dataframe. Since the user can create an unbounded number of filters, I decided to use a for loop to build an executable string that contains all of the filters in one variable that is shown below column = (value selected in "Select Parameter", which corresponds to a column in the dataframe) boolean = (value selected in "Select Condition" e.g., >, <, >= ect.... user_input = (value user inputs into field e.g., 2019 and Diabetes) executable = 'df = df[df[' + column1 + '] ' + boolean1 + user_input1 + ' and ' + 'df[' + column2 + '] ' + boolean2 + user_input2 + ' and '..... exec(executable) While this method works, it leaves my code very vulnerable to injection. Is there a better way of doing this? -

In DjangoRestFramework, is it expected that a MultipleChoiceField default attribute is ignored? [duplicate]
I have the following request serializer using a MultipleChoiceField class CompletedOrderStatusDefault: requires_context = False def __call__(self, serializer_field): # -----> this code is never hit?! return [OrderStatus.COMPLETED] class OrderListRequestSerializer(serializers.Serializer): ... order_statuses = serializers.MultipleChoiceField( required=False, default=CompletedOrderStatusDefault, choices=AllowedOrderStatus.ALLOWED, ) the code in the call is never hit during a request and the value for the field is instead an empty set.

Adding a button to export to a csv/xlsx file on Wagtail Dashboard
I am attempting the solution mentioned in this stack overflow post (Adding a button to Wagtail Dashboard) however the solution might be outdated, or at least it doesn't work for me and I'm unsure why. Goal: Be able to export a object's data to csv First, the button HTML code had to be slightly adjusted to be formatted correctly like so: {% extends "modeladmin/index.html" %} {% block header_extra %} <div class="right"> <div class="addbutton" style="margin-left: 2em;"> {% include "modeladmin/includes/button.html" with button=view.button_helper.export_button %} <a href="#" class="button bicolor icon icon-download">My button</a> </div> </div> {{ block.super }}{% comment %}Display the original buttons {% endcomment %} {% endblock %} and then I copied and pasted the views and helper functions: from django.contrib.auth.decorators import login_required from django.urls import reverse from django.utils.decorators import method_decorator from django.utils.functional import cached_property from django.utils.translation import ugettext as _ from wagtail.contrib.modeladmin.helpers import AdminURLHelper, ButtonHelper from wagtail.contrib.modeladmin.views import IndexView class ExportButtonHelper(ButtonHelper): """ This helper constructs all the necessary attributes to create a button.

Render html tags in Django send email
I found a tutorial on how to send email with Django. This works as intended. However, when I apply html tags, it is being read as a string. Probably because of render_to_string function, but any ideas how to proceed on this? This is my view to send email: current_site = get_current_site(request) mail_message = render_to_string('send/email_template.html', { 'name' : name, 'domain':current_site.domain, }) And this is my email template: {% autoescape off %} <html> Hi {{ name }}, <div class="form-control">......</div> </html> {% endautoescape %} As for the result, it is this: <html> Hi Name, <div class="form-control">......</div> </html> -

Foreign Key with db_constraint= False and postresql: foreign key appears to refer to wrong parent field
I am preparing tables for use in an analytics tool (Microsof Power BI). It would be helpful to show relationships between the tables to assist in report building. However, I don't want to use foreign keys with constraints because the method of data updating and integrity checking doesn't need constraints, and it will actually get in the way. Some of the alternate backends this code supports are for cloud databases that don't offer real foreign keys. I mention that because it means I am trying to define a foreignkey field like this: order_guid = models.ForeignKey("Dear_sales_header",to_field="order_guid",db_constraint=False,on_delete=models.DO_NOTHING) The migration file has this: operations = [ migrations.AlterField( model_name='sales_fact', name='order_guid', field=models.ForeignKey(db_constraint=False, on_delete=django.db.models.deletion.DO_NOTHING, to='dear_zoho_analytics.Dear_sales_header', to_field='order_guid'), ), ] This table is routed to a different database python manage.py migrate --database=dear_analytics does indicate that the migration file was applied (it is 0026) Applying dear_zoho_analytics.0026_auto_20210217_2245... OK But when I inspect the postgresql schema in my IDE, the column in sales_fact is renamed to order_guid_id so it looks like I have done something wrong because this seems to reference the id field of the "parent table" dear_sales_header yet I need it to refer to dear_sales_header.order_guid which is unique but not the primary key. -
Get Response Cookies from Django redirect to SAP application VueJS
I'm working with Django 3.1 backend and Vue js frontend frameworks. The authentication is done by JWT tokens, however, I'm implementing the SSO authentication with SAML. The problem arises when I have to pass the JWT Tokens to VueJs after the SAML authentication is done. Then, the flow is something like this: View in frontend has a button to authenticate with SAML. It is redirected to http://backend/idp?=myIdp Backend go to IDP and IDP prompts to the user the credentials box. IDP redirects the successful SAML response to the backend. Backend generates the JWT for the session, log out the user, and redirected with response cookies for JWT tokens. The frontend view is shown to the user but I cannot get the cookies In the following diagram, I surrounded the part where I'm stuck (credits: https://jcbaey.com/oauth2-oidc-best-practices-in-spa) My redirected code looks like this: class Saml2JwtView(LoginRequiredMixin, RedirectView): url = "http://proxy.localhost/candidates/myServices" def get(self, request, *args, **kwargs): # Obtain JWT tokens for logged in user refresh = RefreshToken.for_user(request.user) response = super().get(request, *args, **kwargs) # Set JWT cookies response.set_cookie("access", str(refresh.access_token)) response.set_cookie("refresh", str(refresh)) # Logout session created by SAML logout(request) return response My networks show me that I'm setting the set-cookie and the 302 redirected to my … -
How to test Django Custom Forms/Views with .save() and .is_valid() form methods
I'm developing a web application and beginning to write tests for an app within the project 'users'. I'm using Python Unit-Testing and TestCase with coverage. I have approximately 83% tested so far however I can't seem to figure out how I should be testing the form.save() method.
