How can I fill up a form field from views.py in Django?
I am using a function to record the time between which the page is loaded and the user submits the data. In that form, I have created a hidden field so that the admin can see it. However, I am unable to implement my idea since I don't understand how I can submit the time to the form from views.py. If someone can suggest an easier and simpler alternative methods to achieve what I am trying to do, that would be very helpful to me as well. My code is as follows. models.py class Responses(models.Model): question1 = models.TextField() question2 = models.TextField() question3 = models.TextField() timespent1 = models.TextField() forms.py class Question1Form(forms.ModelForm): question1 = forms.CharField() timespent1 = forms.TimeField(widget=forms.HiddenInput()) class Meta: model = Responses fields = ('question1','timespent1') views.py def qone(request): if request.method =="GET": starttime = my_timer() elif request.method == "POST": form = Question1Form(request.POST) if form.is_valid(): endtime = my_timer() timespentstr = '{0} seconds'.format(endtime-starttime) #Do something to set timespent1 field = timespentstr here form = form.save() else: form = Question1Form return render(request,'question1.html',{'form':form}) -

replacing django_background_task with APScheduler in Django?
Now I made code that removes temp folder after 5 seconds when users download the file with django_background_task library. I have to replace it with APScheduler library because heroku only supports APScheduler. But I have no idea how to schedule jobs that runs after 5 seconds when I call it. Here is the code. @background(schedule=5) def task_delete_zipfile(filePath): if os.path.exists(filePath): shutil.rmtree(filePath) logging.info("successfully deleted") else: logging.info("unable to delete") zipdir = condown(idx)#returns directory after creating the temp directory if os.path.exists(zipdir): with open(zipdir, 'rb') as fh: response = HttpResponse(fh.read(), content_type="multipart/form-data") response['Content-Disposition'] = 'inline; filename*=UTF-8\'\'%s' % urllib.parse.quote(os.path.basename(zipdir).encode('utf-8')) task_delete_zipfile(os.path.dirname(zipdir)) return response raise Http404 Thanks in advance! -

How to write correct test with pytest-django?
I am getting started with pytest. I try test my ListView with predefined data, but response.context_data['object_list'] is empty. What wrong?

Django - Adding a part of a string onto a new line not working correctly
In my Django project, If the user makes a mistake when signing up, then an error is sent to my template and then displayed. Some of my error messages I send to the user are a bit lengthy, and therefore I want to start a new line within the text. I attempt to add \n within my text, however a new line isn't started. Here's my code: views.py: return render(request, 'users/signup.html', {'error': 'Username field must be \n a minimum of 5 characters'}) signup.html: {% if error %} <span class="errorspansignup"> {{ error }} </span> {% endif %} The text I pass as error stays all on one line. Does anybody know what the issue is? Thank you. -
Error occured in django when i run a command `python manage.py runserver`.after i changed python version
everyone here in stackoverflow. I had successfully completed few django projects few month ago. Now, due to some reason i changed the python version. And when i try to run old django projects it throws the error like following (myDjangoEnv) E:\django_project\thirdpolehandicraft\myDjangoEnv\thirdpolehandicraft>python manage.py runserver Traceback (most recent call last): File "manage.py", line 8, in <module> from django.core.management import execute_from_command_line File "E:\django_project\thirdpolehandicraft\myDjangoEnv\lib\site-packages\django\__init__.py", line 1, in <module> from django.utils.version import get_version File "E:\django_project\thirdpolehandicraft\myDjangoEnv\lib\site-packages\django\utils\version.py", line 1, in <module> import datetime ModuleNotFoundError: No module named 'datetime' The above exception was the direct cause of the following exception: Traceback (most recent call last): File "manage.py", line 14, in <module> ) from exc ImportError: Couldn't import Django. Are you sure it's installed and available on your PYTHONPATH environment variable? Did you forget to activate a virtual environment? Actually when i create new project and run it works fine. But when i activate old virtualenv and try to run the server then above error occurs. Even I did python uninstall completely and installed fresh python again but did'nt work for me. Any body know how to solve this? Thanks in advance! -

Password Reset issue with Django 2.2.5
I am trying to figure out an issue I'm having with what happens after submitting the password reset form supplied by django.contrib.auth.urls. When hitting the button to request the submit button an email is sent properly to the email associated with the user account, but a 505 error page is displayed. In looking at the error log the error given is: Reverse for 'password_reset_done' not found. 'password_reset_done' is not a valid view function or pattern name. In myproject/urls.py I have the following line as part of the urlspattern: path('accounts/', include('accounts.urls', namespace = 'accounts')) In accounts/urls.py I have the following lines as part of the urlspattern: path('', include('django.contrib.auth.urls')) I think the issue is with django attempting to use the equivalent of url 'password_reset_done' instead of url 'accounts:password_reset_done'. Any help in tracking this down would be appreciated. -

Pulling several Django models together into a single list
I have a database with four related tables: project, unit, unit_equipment, and equipment. A project can have many units; a unit can have many related equipment entries. A single unit can only belong to one project, but there is a many-to-many between equipment and unit (hence the unit_equipment bridge table in the DB). I'm using Django and trying to create a view (or a list?) that shows all 3 models on the same page, together. So it would list all projects, all units, and all equipment. Ideally, the display would be like this: Project --------- Unit ------------- Equipment Project 1 first_unit some_equipment1, some_equipment2 Project 1 second_unit more_equipment1, more_equipment2 Project 2 another_unit some_equipment1, more_equipment1 Project 2 and_another_unit some_equipment2, more_equipment2 but at this point I'd also be happy with just having a separate line for each piece of equipment, if comma-separating them is a pain. I am very new to Django, and although it seems straightforward to create a form where I can add a new project, and add related unit and equipment data (using the TabularInline class), I cannot for the life of me figure out how to bring this data together and just display it. I just want a "master … -
Checking a value of single cell on uploaded excel file on Django via openpyxl
I am currently taking an excel file as an input from Django. From the uploaded excel, I would like to check a value in one cell and decide on what to do with the entire workbook. But my syntax for load_workbook must be wrong as I am getting 'stat: path should be string, bytes, os.PathLike or integer, not UploadFileForm' What would be the simplest way to interpret the uploaded file as an excel file and check a value of the single cell? From the upload function, if self.request.method == 'POST': form = UploadFileForm(self.request.POST, self.request.FILES) if form.is_valid(): # edit workbook = load_workbook(filename=form, read_only=True) uploadable(workbook) I cannot change the part above the edit tag as it is being used by many different working functions.

In models.py I have: from django.db import models from children.models import Child from django.contrib.auth.models import User class OrderLineItem(models.Model): order= models.ForeignKey("Order", null=False, on_delete=models.CASCADE, related_name="order") child = models.ForeignKey(Child, null=False, on_delete=models.CASCADE) donation = models.IntegerField(blank=False) def __str__(self): return "{0}-{1}".format( self.donation, self.child.name) class Order(models.Model): full_name = models.ForeignKey(User, blank=False, on_delete=models.CASCADE) phone_number = models.CharField(max_length=20, blank=False) country = models.CharField(max_length=40, blank=False) postcode = models.CharField(max_length=20, blank=True) town_or_city = models.CharField(max_length=40, blank=False) street_address1 = models.CharField(max_length=40, blank=False) street_address2 = models.CharField(max_length=40, blank=True) date = models.DateField() orderlineitem = models.ForeignKey(OrderLineItem, on_delete=models.CASCADE, related_name="orderlineitem") def __str__(self): return "{0}-{1}-{2}".format(self.id, self.date, self.full_name) In the html I have: {% if orders %} <h3>Your donations history: </h3> {% for order in orders %} <div class="history"> <h4>Order number: {{order.id}}</h4> <ul class="history-list"> <li scope="row">Date of your order: {{ order.date }}</li> <li scope="row">Child: {{ order.child }}</li> <li scope="row">Donation: {{ order.donation }} €</li> </ul> </div> {% endfor %} {% else %} <h3>You have not made any donations yet. </h3> {% endif %} And I get an error: Traceback: File "/usr/local/lib/python3.6/dist-packages/django/db/backends/utils.py" in execute 64. return self.cursor.execute(sql, params) File "/usr/local/lib/python3.6/dist-packages/django/db/backends/sqlite3/base.py" in execute 328. return Database.Cursor.execute(self, query, params) The above exception (NOT NULL constraint failed: checkout_order.orderlineitem_id) was the direct cause of the following exception: File "/usr/local/lib/python3.6/dist-packages/django/core/handlers/exception.py" in inner 41. … -
Nginx - how to serve protected video on a rendered page in Django, instead of a forced download?
I need a protected video file on a page rendered by Django. The file is protected, but it's not serving an html rendered page with the <video src="..."> as I'd expect, like netflix. Instead, all I get is a jumbled mess like this image. I know the internal redirect is serving the file, therefore it shows up like that, but I need it on a rendered page with the other html like netflix does.... What am I doing wrong?? Nginx conf file: location /secret_videos/ { internal; alias /home/username/path/to/secret/videos/; } Url: path('protected_video/', views.protected_video, name='protected_video'), View: def protected_video(request): .... if request.method =='POST': if some_var == 'the_correct_value': protected_uri = '/secret_videos/secret-vid-1.mp4' response = render(request, 'template.html', {'some_var ': True, 'protected_uri': protected_uri}) response['X-Accel-Redirect'] = protected_uri return response return render(request, 'template.html', {}) Template, but it's not rendering html, only the image above: <video width="75%" height="auto" controls> <source src="{{ protected_uri }}" type="video/mp4" /> Your browser doesn't support the mp4 video format. </video> -
Link To Config File And Use That Info To Link To Another Config File In Django View
I was wondering if it was possible to link to two config files at the same time in a django view (context)? So I have my main config.py file in my main app folder and another one is stored at themes/default/config.py to store info for that theme so I want to call that configs "THEME_PATH" and use that to link to the themes config.py file to use in the template. main config.py: SITE_NAME = 'Site Title' THEME_PATH = 'themes/' SITE_THEME = 'default' themes/default/config.py: # Homepage HOMEPAGE_TITLE = 'Home' HOMEPAGE_DESCRIPION = 'Welcome to our site!' HOMEPAGE_KEYWORDS = '' # Forums FORUM_TITLE = 'Forums' FORUM_HEADER_TITLE = 'Welcome To Our Site' FORUM_HEADER_TEXT = 'Welcome to the forums a place to talk about anything.' FORUM_DESCRIPION = 'This is our forum' FORUM_KEYWORDS = '' views: from django.shortcuts import render, import app.config def forums_home_view(request): # ... context = { 'site_name': app.config.SITE_NAME, 'forum_title': app.config.THEME_PATH.SITE_THEME.config.FORUM_TITLE, 'forum_description': app.config.THEME_PATH.SITE_THEME.FORUM_DESCRIPION, 'forum_header_text': app.config.THEME_PATH.SITE_THEME.FORUM_HEADER_TEXT, 'forum_keywords': app.config.THEME_PATH.SITE_THEME.FORUM_KEYWORDS, } return render(request, f"{app.config.SITE_THEME}/forum_home.html", context) I tried doing it like app.config.THEME_PATH.SITE_THEME but that didn't work also tried a few others way and also didn't work so any help will be great -
Django: No module named 'psycopg2' when launching migrations to heroku
I am new to django and I created a website and now I am in the deployment phase, all is well run until launching migrating from the database to the server.

Saving ManytoMany fields in Django with multiple forms
I am trying to do the following in 3 forms that are processed at once: 1. Save the subject line for an email (this works) 2. Save the email content. (this works) 3. Save the email title (works) and save the relationship to the subject line and to the email content (not working). I have read through every page I could which had to do with errors. I have tried it a variety of different ways, but they all haven't worked for me. View.py: def email_subject_create_view(request): if request.method == 'POST': email_subject_form = EmailSubjectForm(request.POST) email_content_form = EmailContentForm(request.POST) email_form = EmailForm(request.POST) if email_subject_form.is_valid() and email_content_form.is_valid() and email_form.is_valid() : subject = email_subject_form.save(commit=False) subject.time_created = datetime.datetime.now() contractor = Contractor.objects.get(user_id=request.user.id) subject.save() email_subject_form.save_m2m() content = email_content_form.save(commit=False) content.time_created = datetime.datetime.now() content.save() email_content_form.save_m2m() email = email_form.save(commit=False) email.time_created = datetime.datetime.now() correct_subject = EmailSubject.objects.get(pk=subject.id) # this is what I want to do. email.email_core_contents is a M2M field email.email_core_contents = subject.id email.save() context = { 'email_subject_form': EmailSubjectForm(), 'email_content_form': EmailContentForm(), 'email_form': EmailForm(), } return render(request, 'advertise/email_subject_create.html', context) I have tried: email.email_core_contents = EmailSubject.objects.get(pk=subject.id) email.email_core_contents.set(subject) email.email_core_contents.set(pk=subject.id) I have also tried it without the .save_m2m() portions of code. -
Visual Studio Code switching terminals when debugging. Code only runs successfully once with debugger
I am trying to debug Django code with Visual Studio Code on windows 10. When I run the debugger for the first time, my code compiles successfully and nothing goes wrong. If I change something in the code, and rerun the debugger I get a giant slew of commands on my Python Debug console run into the same error report I ran into before (from the first run even with new code without any user interaction on my webapp). Some notes: It seems very consistent. If I close visual studio code and rerun it-- my code runs fine... for one run. Closing the python debug console, it reruns fine on my default terminal--powershell.
