Bypass the ordering inside the Meta class
I have two models: class Member(models.Model): course_member = models.ForeignKey(CourseMember, on_delete=models.CASCADE class Meta: db_table = 'member' ordering = ['-id'] class CourseMember(models.Model): name = models.CharField(max_length=30) When I try running. Member.objects.values('course_member').aggregate(Count('id')) I keep getting the wrong order_by. instead of grouping by course_member, it keeps grouping by member_id. The Django docs warn about this issue, see link. I'm trying to see if there is a solution to bypass this issue instead of just waiting for Django 3.1 -
How do I tell POpen to use/set certain environment variables?
I'm using Python 3.7 and Django. I use the below to run a command I would normally run in the shell ... out = Popen([settings.SELENIUM_RUNNER_CMD, file_path], stderr=STDOUT, stdout=PIPE) t = out.communicate()[0], out.returncode his dies with the error b'env: node: No such file or directory\n' What I'm trying to figure out is how to give my Python environment access to the normal environment variables I have access to, or figure out a way to set them before I run my Python command. Normally "node" is easily found when I check as myself davea$ which node /usr/local/bin/node But I don't know how to tell Python to use the same PATH that I have access to. -
Django model form field: use disabled but still pase (calculated) values to form.is_valid()
Assume I have a model class A with a mandatory text field b (and other fields). I want to create a model form where under certain circumstances (determined in the form's __init__) the value for b is calculated and not shown in the form. It seems that setting disabled is the way to go, which, according to this docs entry, will ignore any value passed but instead use "the form’s initial data". However, the following does not do what I hoped it would do: class A(models.Model): b = models.TextField() c = ... class MyForm(forms.ModelForm): class Meta: model = A fields = ('b', 'c', 'd') def __init__(self, *args, **kwargs): if complicated_test(*args, **kwargs): field = self.fields['b'] field.disabled = True field.initial = 'Bla' This does disable the field, but seems to ignore the manually given value Bla, which in my case will make form.is_valid() fail (as my model really expects Bla to be in there). Questions: Is field.initial = 'Bla' really supposed to fail in this situation, or it this a weird bug in my setup? If no bug: Can I set "the form’s initial data" in some other way? What alternatives are recommended? In my case, I do not see a natural … -
django-heroku installation giving an error
I'm trying to deploy my app to heroku but after executing pip install django-heroku it gives me an error. I'm running Python 3 with Django 2.2 on a mac.

Elasticsearch create index error on Heroku
I have a django application that uses elasticsearch with the django-elasticsearch-dsl package as an integration. Locally I'm using docker compose to host my django and elasticsearch services and after some setup everything is working fine. I'm hosting the app on heroku with the bonsai add-on and am getting the following error when running ./manage.py search_index --rebuild to create the index on the heroku bonsai elasticsearch instance. elasticsearch.exceptions.RequestError: RequestError(400, 'mapper_parsing_exception', 'Root mapping definition has unsupported parameters: [receiver : {type=text}] [sender : {type=text}] [created_at : {type=date}] [id : {type=integer}] [text : {type=text}] [source : {type=text}] [title : {type=text}]' ) I've played around with my local elasticsearch version and flavor to get it to be as similar as possible to the deployed instancem, but can't get the error to reproduce to debug it.

Custom ordering on a many to many relationship
I'm trying to implement a model that represents sorted lists of items, without having to specify the sort order every time I'm unable to find a way to customize the get_queryset() method of the forward many-to-many relationship manager from django.db import models class Item(models.Model): name = models.CharField(max_length=50) class Meta: ordering = ['name'] class List(models.Model): name = models.CharField(max_length=50) items = models.ManyToManyField(Item, through='Listing')) class Listing(models.Model): list = models.ForeignKey(List, on_delete=models.CASCADE) items = models.ForeignKey(Item, on_delete=models.CASCADE) index = models.SmallIntegerField() class Meta: ordering = ['index'] I would like Item.objects.all() to be sorted by name (working), and List.objects.get(pk=1).items to be sorted by listing.index (not working; also sorted by name) -
Django - How to retrieve columns in template automatically from a query in views.py?
There is a module with 30 columns. I query this table in the views.py to get the last record (last row). To get the data in template (index.html), I have to write each column and in front of it, its value. I have to do it 30 times! is there anything like {{form}} to get all the columns and their value automatically or at least by using {% for ... %}? in views.py def articlesindex(request): data = Articles.objects.all().last() return render(request, 'Articles\index.html', {'articles':data}) in index.html {{ articles }} (does not work) {{ articles.a_table }} (does not work) {% for k,v in articles %} (does not work) <tr> <td>{{ k }}</td> <td>{{ v }}</td> </tr> {% endfor %} -
Can Email Validators overwrite clean() method?
Problem: I am attempting to write a clean() method on my Django forms class and for the most part, it is working (Password validation is working but not email?). My goal is to compare two email fields and two password fields to each other and raise a validation issue if they do not match. I have tried using the raise forms.ValidationError() as detailed in the Django docs here, however I would prefer to display the validation error on both fields so I am trying to use the self.add_error('field', msg) method instead as detailed on the same page. My attempt: forms.py class userRegistrationForm(forms.Form): # field definitions here def clean(self): cleaned_data = super(userRegistrationForm, self).clean() email1 = cleaned_data.get('email') email2 = cleaned_data.get('emailConfirm') password1 = cleaned_data.get("password1") password2 = cleaned_data.get("password2") if password1 != password2: msg = 'Your Passwords do not match...' self.add_error('password1', msg) self.add_error('password2', msg) elif email1 != email2: msg = 'Your emails do not match...' self.add_error('email', msg) self.add_error('emailConfirm', msg) Exact error: What ends up happening, is the first email field validates with no errors no matter what and if there is a mismatch, the error only shows up on the second field, unless I type out the full correct email address, then that field also … -
Django-allauth, how do I change the url in my email confirmation email?
friends. Used Django-allauth package for authorization in django project. The project is located in the Docker container (with parameter -p 8002:8001) on the server with the domain(testsite.com). When I run the container on the command line, I run the python command manage.py runserver 0.0.0.0:8001. In the admin panel specify the domain of the site. The problem is that django-allauth sends an email to confirm the email type - http://127.0.0.1:8002/accounts/confirm-email/MQ:1hjJgA:XFqIW130fMBQ5_blim_KVxYsVXg/. In the package code found that the url is used to build the site.domain - but when the variable is output to the console - get the correct domain of the form - testsite.com ahhh! I can not understand what variable to override or how to make to get the desired url of the form - http://testsite.com/accounts/confirm-email/MQ:1hjJgA:XFqIW130fMBQ5_blim_KVxYsVXg ahhh! Can who knows as solve this question? -
Django-Rest: Need to get all data in batch wise from oracle
I need to create Django rest API- fetching data from Oracle DB, apply pagination, send back to response. For that, I am taking no_of_rows_per_page and page_no, and fetching all data. I am using fetchall() method. By this method we are getting all data from DB first, then pagination apply and send back as response. By this process, we need to call next page data, we are getting the same process again(Loading all data again from DB). For that our application is taking too much time (Database connected through VPN and Table having millions of records) For this, I need to fetch data in batch, for that, I used fetchmany(no_of_rows_per_page) method and returning back as response. Since Oracle return each time random rows, getting duplicate/same rows in next page call. Help needed on this. Thank you. -

Replacing Basic Auth in Django Rest Framework
I currently have Django basic auth setup with Knox token authentication. Basic Auth doesn't seem sufficient for production work, so I want to replace that. Does Django have another password-based authentication_class that I can easily replace BasicAuthentication with, or is this a more involved process? If so, where do I start? my login api view: class UserLoginView(GenericAPIView): serializer_class = UserOrganizationSerializer authentication_classes = (BasicAuthentication,) permission_classes = (IsAuthenticated,) def post(self, request): """User login with username and password.""" token = AuthToken.objects.create(request.user) return Response({ 'user': self.get_serializer(request.user).data, 'token': token }) my default authentication classes: REST_FRAMEWORK = { 'DEFAULT_PERMISSION_CLASSES': [], 'DEFAULT_AUTHENTICATION_CLASSES': [ 'rest_framework.authentication.SessionAuthentication', 'rest_framework.authentication.BasicAuthentication', ], -
GIF Erroring on Network
I'm not quite sure if this is a Django issue, an HTML issue, or something else so apologies if this isn't properly tagged. I have an application where a user submits an Elasticsearch query and a report is then generated. Depending on the number of results the query returns, the report can take quite a while to generate. As a result, I'd like to put a gif of a spinner so the user understands that it's still processing (instead of me just explicitly saying it's still going). I have ajax-loader.gif in my project/static/ folder but it doesn't seem to recognize that it exists because it's giving me a 404 error. Additionally, it's classifying the type as "text/html" instead of "gif". How can I get the gif to load in? html <!-- templates/django_audit/check.html --> {% extends 'base_login.html' %} {% block title %}Please wait{% endblock %} {% load static %} {% block content %} <script type='text/javascript' src="{% static "bootstrap/js/jquery/1.7.1/jquery.min.js" %}"></script> <script type="text/javascript"> $(document).ready( function() { var fn = $('#fn').val() var checkInterval = setInterval(isFileComplete, 3000); //1000 is 1 second function isFileComplete() { $.ajax({ url: '/check_progress/', type: 'POST', data: { 'filename': fn, 'csrfmiddlewaretoken': '{{ csrf_token }}', }, dataType: 'json', success: function (data) { if … -
What's behind the mechanism of Django models and fields?
What is the Django/Python mechanism behind the Django model/field part of framework? To be exact, I am looking for a hint on how Django parses (?) class definition and then knows which fields are required? from django.db import models class Car(models.Model): name = models.CharField(max_length=255, null=True, blank=True) year_of_production = models.DateField(null=True) # the rest of fields... I think the same mechanism is behind Django Forms framework or DRF serializers. I checked repos of these projects but I still can't find any reasonable starting point. There's a architectural problem under my question. I think I need to implement something similar to this mechanism: class Field: def __init__(self, label: str, required: bool = True, **kwargs): self.label, self.required = label, required class CharField(Field): def __init__(self, max_length: int, **kwargs): self.max_length = max_length super().__init__(**kwargs) class DateField(Field): ... class BooleanField(Field): ... class Model: # the mechanisms I do not understand class MyModelInstance(Model): name = CharField(...) # etc. What I need is really simple solution that knows that field is required. But as I stated before I am not that advanced and I would really appreciate any hints. -
How can I know the space left in a pdf page?
I have a pdf with 3 sections and I had to add a page break for each section but now I have to know if the section 3 is smaller and can go into in the same page with section 2, but the tricky part is if section 3 is more than the space left in the page after section 2 I have to add the page-break. What I mean is if I can know where section 2 ends in a page and if I can know the space left in that page, and in the space left can section 3 be. The actual is that section 3 goes after section 2 and when section 3 is longer than the space left for section 2, it does in that way. I expected if section 3 is longer than the space left in the page after section 2 should be a page break, if not so section 3 should go after section 2 on the same page. -

Here is my code for the mode view set create method override: @permission_classes((IsAuthenticated)) def create(self, request, *args, **kwargs): print(request) namespace = self.kwargs.get('namespace', None) path = self.kwargs.get('path', None) if namespace is None and path is None: return super().create(request) if namespace and path is None: data = { "person":self.request.user, 'version':request.POST['version'], 'namespace':namespace, 'path':request.POST['path'], 'value':request.POST['value'], 'user_id':request.user['id'], } return super().create(data) if namespace and path: data = { "person":self.request.user, 'version':request.POST['version'], 'namespace':namespace, 'path':path, 'value':request.POST['value'], 'user_id':request.user['id'], } return super().create(data)
