Passing static path to included template
Is it possible to pass a static path as a variable to an included template? I need to repeatedly include a template on my page but its always with different logos. For example: {% with img={% static 'img/dashboards/belgium_flag.svg' %} %} {% include 'dashboards/charts/country_block.html' %} {% endwith %} {% with img={% static 'img/dashboards/netherlands_flag.svg' %} %} {% include 'dashboards/charts/country_block.html' %} {% endwith %} This doesn't work.. Is there any workaround to this besides creating a model to support an image attribute to each Country instance? -

Django GraphQL Test: How to test addition of new model fields?
I have a simple model as, class Person(models.Model): first_name = models.CharField(max_length=20) and I have setup the GraphQL to query the data, import graphene import graphene_django from .models import Person class PersonType(graphene_django.DjangoObjectType): class Meta: model = Person fields = '__all__' class PersonQuery(graphene.ObjectType): persons = graphene.List(PersonType) def resolve_persons(*args, **kwargs): return Person.objects.all() So far so good. Later I decided to write unittests for querying the persons data from django.test import TestCase from .models import Person from .schema import schema class TestGraphQLQuery(TestCase): @classmethod def setUpTestData(cls): cls.person = Person.objects.create(first_name="Jack") def test_person_query(self): query = """ query{ persons { id firstName } } """ result = schema.execute(query).data expected = {'persons': [{'id': f'{self.person.pk}', 'firstName': self.person.first_name}]} self.assertEqual(result, expected) and this too working. Later, my model got updated with one additional field, age and hence the model updated to class Person(models.Model): first_name = models.CharField(max_length=20) age = models.IntegerField(default=0) After the changes, I ran the unittests. As expected, it passes. Question How can I create the test case so that, the test should fail upon addition or removal of any fields? -

django - How can I prefill formset forms data using database query result?
I am creating a student attendance form where need to get details of student name, student class and Id from student model based on teacher selecting student class in one form. I have tried using initial by using for loop on query data to prefill the form in formset, however it populates data for one record only. Below is the code for forms.py, models and views.py.

Django still refreshing the page after integrating AJAX
In index.js: $("#weather_form").on("submit", function(event){ event.preventDefault(); $.ajax({ url: "/weather/", type: "POST", data: {...:..., ...:..., ...}, success: function (data){ alert("success") }, error: function(xhr,errmsg,err) { alert("error") } }); }); In views.py: class weather(base.TemplateView): ... @staticmethod def post(request, *args, **kwargs): ... if request.is_ajax and request.method == "POST": ... if form.is_valid(): ... return http.JsonResponse({"results_matrix": results_matrix.tolist()}, status=200) else: return http.JsonResponse({"error": form.errors}, status=400) What's happening now is when I click submit, Django clears the entire page and then print the correct results_matrix on a blank page in string format. alert("success") does not appear or alert("error"). I don't know why the post function is doing this since I'm not returning a render of anything. -

PyQt based desktop application which has a subscription based model
I have developed a desktop application in python using PyQt5 which acts as a UI for the hardware I am trying to sell. I want to convert this desktop application into a SaaS(software as a service) where people will buy the hardware and then subscribe to the software to be able to use the hardware. My question is how do I add this functionality. I don't have much of an experience with web servers. Although I do understand that I will have have a server which will handle the requests from the PyQt app and also a database to store the information about the subscription. I am ready to learn Django or flask. How will I make the software secure, in the sense people won't be able to bypass the subscription and use the app indefinitely. I also do understand that there will be some piece of code written in python (probably using Django) running in the backend of the web server. How will the Django backend interact with a database. I also don't understand how will the PyQt app connect to the server. How will the PyQt app check for the subscription? Obviously there will be a login page. … -
How to follow a link without creating templates in Django

Django: Performing a raw sql query with count()
I want to make a query to get the number of rows in the model MyTable that have the field expire (datetime) be a date in the current week. In MySQL I execute the following query: select count(expire) from MyTable where yearweek(expire) = yearweek(now()); So I can get the rows that belongs to the current week starting from Sunday. I tried replicate that using queryset in my view like this: now = datetime.now() myquery = MyTable.objects.filter(expire__year=now.year).filter(expire__week=now.isocalendar()[1]) But the thing is, Django method of querying starts from Monday, I want it for Sunday. So I though in doing a raw sql query Like this: myquery = MyTabel.objects.raw('select count(expire) from MyTable where yearweek(expire) = yearweek(now());') But it doesnt work, it doesnt output a value. How can I make this query? I'm using mysql 5.7, python 3.7 and django 2.1.11 I know these are all old versions but I can't update. -

How to use Relay's pagination feature with filterset_class from django-filter when using graphene-django
I've a Django project where I'm using django-graphene to create a GraphQL API. There's an issue when trying to use DjangoFilterConnectionField together with the relay.Connection (which is the core of pagination's feature) My model is too large and has many relationships, but let's keep things simple... class Pattern(models.Model): code = models.CharField( max_length=15 ) name = models.CharField( max_length=50 ) slug = AutoSlugField( populate_from='name', max_length=150 ) ...

Django-CSP - AJAX request with vanilla JS blocked by CSP
I have a Django-based D&D-wiki webpage that I'm working on in my free time which I'm using to learn more about web development. I recently implemented a Content-Security-Policy using django-csp. That went well and the switch was fairly painless, given that I only had 20 or so templates to deal with. Here my CSP settings: //Django settings.py CSP_DEFAULT_SRC = ("'none'",) CSP_STYLE_SRC = ("'self'", 'stackpath.bootstrapcdn.com', 'fonts.googleapis.com', "'unsafe-inline'", 'cdn.jsdelivr.net', 'cdnjs.cloudflare.com', 'rawcdn.githack.com', 'maxcdn.bootstrapcdn.com',) CSP_SCRIPT_SRC = ("'self'", 'localhost', "default-src", 'stackpath.bootstrapcdn.com', 'code.jquery.com', 'cdn.jsdelivr.net', 'cdnjs.cloudflare.com','maxcdn.bootstrapcdn.com',) CSP_IMG_SRC = ("'self'", 'ipw3.org', 'data:', 'cdn.jsdelivr.net', 'cdnjs.cloudflare.com', 'i.imgur.com',) CSP_FONT_SRC = ("'self'", 'fonts.gstatic.com', 'maxcdn.bootstrapcdn.com',) CSP_MEDIA_SRC = ("'self'",) CSP_INCLUDE_NONCE_IN = ('style-src',) Even more recently started learning about AJAX requests and wanted to implement a simple POST request. Sadly, my CSP blocks this request, which I believe should be allowed given that I allowed self and localhost in CSP_SCRIPT_SRC: //JS Event Listener that creates and sends the AJAX request document.getElementById('create-timstamp').addEventListener('click', function(event){ const isValid = validateForm(); if (isValid){ xhr = new XMLHttpRequest(); xhr.open('POST', getCreateTimestampURL(), true); xhr.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded; charset=UTF-8'); const csrf = document.querySelector('input[name="csrfmiddlewaretoken"]').value; xhr.setRequestHeader("X-CSRF-TOKEN", csrf); xhr.onload = function(){ document.querySelector('.timestamp-create-box').remove(); } const timestampForm = document.forms['timestamp-form']; const timestamp_seconds = toTimeInt(timestampForm['time'].value); const timestamp_name = timestampForm['name'].value; const data = `name=${timestamp_name}&time=${timestamp_seconds}`; xhr.send(data); return false; } //For completion's sake here also the … -

Djnago admin.StackedInline logic to automatic clone related models
I have a model A with oneToMany relationship with Model B. Django admin side, to manage this relationship, I'm using one admin.StackedInline Into this formset I added a custom Integer field 'MYFIELD' (not related to the model). My idea is this: when the user save the model, for each related model, I would like check this MYFIELD to clone this related model. This is a sort of multiplier: for each related model, if the value is N I will create N clones of it. Probably I have to implement this logic into the method save_related but it's not clear for me how can duplicate. -
Reset auto-increment index value on SQLite(Django)
I'm creating a Blog app using Django. So when I delete a post which is at the database index of 3 and adds another post to the blog, it adds the post on the database column of index 4, and there won't be any column of index 3. So How can I change that new post index to 3 itself? -
request.session.modified vs SESSION_SAVE_EVERY_REQUEST
I understand how these work differently in practice. For example, if I have: request.session.['cart'].remove('item') the session won't be saved without explicitly calling request.session.modified = True or having SESSION_SAVE_EVERY_REQUEST = True in settings.py. Or I could get around using either by using: cart = request.session['cart'] cart.remove('item') request.session['cart'] = cart My question is if there is any drawback to using SESSION_SAVE_EVERY_REQUEST whether in performance or unintended consequences. I don't see any reason why I wouldn't want to save the session if I modified a value in it. -
Procfile issue while deploying on Heroku
I am deploying y Django application on Heroku. At first I added the Profile this way: I could run 'heroku local', while in the folder where Procfile with no issue and the app was running fine locally. Then I realized while deploying on Heroku that Procfile had to be in the root directory for it to be recognized. So I changed it's directory: Running 'heroku local' I got an no module names'trusty_monkey.wsgi' error. So I change my Procfile from : web: gunicorn trusty_monkey.wsgi to: web: gunicorn trusty_monkey.trusty_monkey.wsgi But now I have this error: What I don't understand is why it doesn't get the 'trusty_monkey.settings' now when they were no issues before? -
Django / Apache / Ubuntu Static files not being served
Everything was working fine until I moved from my local PC to a web server (AWS Ubuntu). I am using Apache with WSGI adapter. I followed all the guides I could and have been at this for several days and still can't figure out why none of my images or styles are displaying. I am having trouble wrapping my head around how static files work and there may be a simple reason why this isn't working but I can't figure it out. I have followed so many guides and am at a loss. Yes I have run collectstatic, but all this seems to do is throw all my static files into the static folder. Not sure what the purpose of this is and I am having trouble understanding it on the django website.

EBS + Django - MEDIA doesn't work (permission denied)
I have a Django project on Elastic Beanstalk. Now I'm trying to make media work. Since media is a user-uploaded content I guess I can't just use myproject/media folder. When I try to upload/save a file it returns: PermissionError: [Errno 13] Permission denied: '/opt/python/bundle/7/app/media' Do you know what to do? Is there a place that I can use as a media folder that won't be deleted? In settings.py: MEDIA_ROOT = os.path.join(BASE_DIR, 'media') MEDIA_URL = '/media/' -

The page contains a form with label as 'name'. The user will look at the message displayed from rules.py and enter a name in the form and click on 'submit' On clicking submit, the page should POST the request, alongwith the 'name' entered and execute program validate.py, that returns a numeric code (0: success, 1: invalid), and a text (next instruction if success, error message is failure). This text should be displayed back to my page, in the same place where the output from rules.py was displayed earlier. Then based on the message displayed, user will enter another name, and same process will repeat. How to display a text in the form that is output from a python program? I am able to display the output in the label of the input name field, using code below. But I don't want to change the label, I want a paragraph / …
