ModuleNotFound error when trying to do a RequestFactory()
I'm trying to create a python script that runs in the background and periodically runs a view (Celery can't be installed on Azure, django-cron doesn't work). I found that you can use RequestFactory() to generate a request, but I get the following error: ModuleNotFoundError: No module named 'pcbuilder' Here is my external script: from django.contrib.auth.models import AnonymousUser, User from django.test import RequestFactory, TestCase from .views import update factory = RequestFactory() factory = RequestFactory() user = User.objects.get(username='user') request = factory.get('/update') request.user = user response = update(request) As a side question: I had to set my DJANGO_SETTINGS_MODULE environment variable in CMD, is there a way to do it from the .py file itself? -

How to solve Django 'ModuleNotFoundError' ___main___.models

problem installing django-heroku on macos
While installing django-heroku on macOS catalina 10.15.1, I get the following error: ld: library not found for -lssl clang: error: linker command failed with exit code 1 (use -v to see invocation) error: command 'xcrun' failed with exit status 1 At first, it was giving the following error: The error is pg_config is required to build psycopg2 from source. So I searched on StackOverflow and I installed PostgreSQL with homebrew: brew install postgresql as they described and linked it with brew link postgresql and this seemed to installed fine. But now clang cannot link the lssl. I don't understand if this is a problem related to path or permissions. Any help will be really appreciated! -
How to save the user input in the django-filter form field to database (equivalent of form.save())?
I am using django-filter to filter my results according to the user input of a few fields. It works great.I have a "Search" button which filters the result according to the user input and now I want to add another button which should save the user input in some fields to a particular database (I have 2 databases). How would I achieve this? If it was a normal form I usually to form.save() to save the data. But here it is a form generated by django-filter <form method="post" id="info-form"> {% csrf_token %} <div class="well"> <h4 style="margin-top: 0">Filter</h4> <div class="row"> <div class="form-group col-sm-4 col-md-3"> {{ filter.form.title.label }} {% render_field filter.form.title class="form-control" %} </div> <div class="form-group col-sm-4 col-md-3"> {{ filter.form.id.label }} {% render_field filter.form.id class="form-control" %} </div> <button type="submit" class="btn btn-primary" name="display" value="Display"> <span class="glyphicon glyphicon-search"></span> Search </button> All of this works great. Now I'm adding a new button like so: <button type="submit" action="update" class="btn btn-primary" form="info-form" name="save" value="Save">Add</button> This is the views.py: def a_view(request) a_list = ARecords.objects.select_related(‘bid’).filter(…) filter = ItemFilter(request.POST, queryset=a_list) return render(..)

Django On-Click Event Not Triggering
I have this web application that I'm creating that tracks the projects that a user is working on or has completed in the past. I'm trying to use the tags in the template in order to ask for a confirmation before they create a new project only when they have inputted a name that already exists in another category.

Django "NoReverseMatch" error when trying to call a function in views from html
I am trying to display a User's name on top of a box where they enter their Employee # in a form, without having to refresh the page. For example, they enter their # and then after they click/tab onto the next field, it renders their name on top, which comes from the database, so the user knows they've entered the correct info. This name is stored in a separate model, so I try to retrieve it using the "id/number". I am not too familiar with AJAX but after reading a few similar questions it seems like an AJAX request would be the most appropriate way to achieve this. I tried to make a function get_employee_name that returns the name of the person based on the way I saw another ajax request worked, but I'm not sure how to implement this so it displays after the # is entered. I get this error when trying to see the page now, I'm not sure where I'm passing the "id/employee_number" incorrectly which is causing this to show: django.urls.exceptions.NoReverseMatch: Reverse for 'ajax_get_employee_name' with no arguments not found. 1 pattern(s) tried: ['operations/ajax\\/get\\-employee\\-name\\/(?P<id>[0-9]+)\\/$'] models.py class EmployeeWorkAreaLog(TimeStampedModel, SoftDeleteModel, models.Model): employee_number = models.ForeignKey(Salesman, on_delete=models.SET_NULL, help_text="Employee #", null=True, … -

Django rest framework: Foreign key instance is not being passed to validated_data
I'm trying to save data to my database using ModelSerializer but when I pass a ForeignKey instance, it gets converted to the field value after calling is_valid(). I need to pass the instance instead of the value because my Model contains an attribute with a Foreign key and that same attribute is included in unique_together set in the model. My problem is basically the same as this question I checked with the Pycharm Debugger that the foreign key I pass into the serializer remains a Model instance only until the is_valid() is called. As soon as the is_valid() method is called, the foreign key converts to the PK or to the value of a field(if to_field is defined in the model) which ultimately results in the following kind of error: ValueError at /app/core/create-trip Cannot assign "'ChIJTWE_0BtawokRVJNGH5RS448'": "CityAttrRtTb.attr_nm" must be a "CityAttrn" instance. The error above shows that the CityAttrn instance was converted to its respective field value after calling is_valid(). The question I linked to above has an answer that I need to pass the foreign key as an argument to the save() method of the serializer. I can do that if I only have one data. However, I am … -
Aggregation for query items with the same field value
One of my querysets returns list of items with several fields: <QuerySet [{'name': 'John', 'products': 4}, {'name': 'John', 'products': 6}, {'name': 'Sam', 'products': 7}, ...]> How do I aggregate this data to get combined Sum() of products value for elements with the same name field to avoid duplicates in queryset, so as a result I'll have something like this: <QuerySet [{'name': 'John', 'products': 10}, {'name': 'Sam', 'products': 7}, ...]> I understand this should be done using .annotate() or .aggregate() queries but I can't figure out how. -
Django: Extracting the value from a Queryset and store in a variable for filtering later on
I would like to extract a value from a queryset and then store it in a variable so that I can use it as a filter criterion later on. How may I do this? This userprofile model is linked to the User model hence the User.id would be the same as the user_id in userprofile model: class userprofile(models.Model): user=models.OneToOneField(User, ...) age=.... user_race=models.Charfield(.....) I want to get the race of this user and store it as a variable "x", so when I query the following way: x = userprofile.objects.filter(user_id=request.user.id).user_race #doesn't seem to get the race of this user...how to get it? Question: is "x" now a string variable or still a queryset in the form of a list of dictionary? Then I want to use "x" as the criterion when filtering for another queryset using the following model: class cuisines(models.Model): portion=.... race=models.Charfield(.....) Query: y = cuisines.objects.filter(race='x') #This is to get all the results as long as the race of the user matches the race value in the cuisines model. Please help me in better understanding where I have gone wrong in this logic/process. thank you. -
How to run a function in views.py from another Python file

Next Page / Previous Page not working for Django pagination
I was hoping someone could help me with a pagination question. I am trying to use Django pagination following the information on this page (https://docs.djangoproject.com/en/2.2/topics/pagination/). Whilst I have successfully displayed the correct number of items on the first page and the last page works, the next and previous pages keep taking me to the first page. I think the issue may revolve around the ‘request’ element and I’m not sure if I am picking up an incorrect version. The example states:- def listing(request): contact_list = Contacts.objects.all() paginator = Paginator(contact_list, 25) # Show 25 contacts per page page = request.GET.get('page') contacts = paginator.get_page(page) return render(request, 'list.html', {'contacts': contacts}) The command: page = request.GET.get(‘page’) returns “AttributeError: 'Request' object has no attribute 'GET'” By replacing this code with: page = request.args.get('page', type=int) the code successfully renders the first (and last) page but next and previous do not work. As background I built my system on the Flask megatutorial but I have been unable to use that pagination, I understand because I haven’t used the Flask SQL Alchemy for creating and updating databases. My routes file has from flask import request Should I replace this with another utility's “request” and if so, which? -

Django include URLconf module multiple times under different root urls
I want to be able to add optional url parts before all urls (e.g. a version). I could use re_path to do this, but I wonder if it is possible using path as well, since that would offer some other advantages. My current approach looks like this: urls = path("", include('test.urls'), namespace='test') urlpatters = [ path('<version:version>/', include(urls)) path('', include(urls)) ] Implementing it like this, calling the urls works but reversing does not work anymore. Django tells me that the namespaces are not unique: ?: (urls.W005) URL namespace 'test' isn't unique. You may not be able to reverse all URLs in this namespace Why is that? Using re_path with optional url parameters, reverse works as intended and selects the url depending on which parameters are given: reverse('test') # '/' reverse('test', version=1.0) # '/1.0/' -
