Is it possible to deploy django 2.2 on Google cloud engine?
I just began to learn Django recently. I am trying to deploy a django project on google cloud engine. But I stuck when following tutorial on google: https://cloud.google.com/python/django/appengine when I type: python manage.py makemigration I got: following error: mysqlclient 1.3.13 or newer is required; you have 0.9.3. After short research, aparently, I can't install mysqlclient 1.3.13 on Django 2.2 yet?? Is this a mistake? Am I missing something? Can I use mysqlclient 1.3.13 on django 2.2 ? Thank you for your time. -
assertEqual fails in Django test view
I'm testing whether the view returns in the context object all the database models that I've saved. The models actually render in the templates when the site is running but having had problems rendering them in the past, I need the view test to help with debugging. So the test collects then saves the site url to the variable resp using Client. I then assertTrue that the key value passed in the context exists. Then - and this is where the problem lies - i attempt to assetEqual that what's in the context object matches whats in my database and this is the resulting traceback: File "/Users/Sol/src/projects/portfolio/python_website/main/tests_models.py", line 24, in check_context_obj self.assertEqual(resp.context['projects'], Project.objects.all()) AssertionError: <Quer[20 chars] App>, <Project: Folium Web Map>, <Project: Personal Webiste>]> != <Quer[20 chars] App>, <Project: Folium Web Map>, <Project: Personal Webiste>]> You'll notice after the AssertionError the the values either side of the != operator are actually exactly the same (I actually checked that their types are the same). Here are my files: tests_views.py from django.test import TestCase from main.models import Project from django.urls import reverse def check_context_obj(self): url = reverse('site_index') resp = self.client.get(url) self.assertTrue(resp.context['projects']) self.assertEqual(resp.context['projects'], Project.objects.all()) views.py from django.shortcuts import get_object_or_404, render from main.models import … -
What is the difference between “return my_view” and “return redirect(my_view)” and how to get a mixed result?
I have a home in which I have a form that I get some info from students to suggest them some programs to apply to. The home view is as below: def home(request): template_name = 'home.html' home_context = {} if request.POST: my_form = MyModelForm(request.POST) if my_form.is_valid(): # do some stuff return programs(request) else: my_form = MyModelForm() home_context.update({'my_form': my_form, }) return render(request, template_name, home_context) In the second view, I have the same form and I want this form to be pre-occupied with the information I entered in the home page. That is why in the above, I passed my POST request to programs view that is as below: def programs(request): template_name = 'programs.html' programs_context = {} if request.POST: my_form = MyModelForm(request.POST) if my_form.is_valid(): # do some other stuff else: my_form = MyModelForm() programs_context.update({'my_form': my_form, }) return render(request, template_name, programs_context) The drawback of this strategy (passing the POST request in the home view to the programs_view) is that the url in url bar does not change to 'example.com/programs' and stays as 'example.com' . I will have some problems including problems in pagination of the programs. The alternative is that I do this: def home(request): template_name = 'home.html' home_context = {} if request.POST: … -

Django 2.2 static files not showing/processing
I'm trying to deploy my Django instructor's (Udemy) 'real estate' project. Here is Brad Traversy’s gist. I've followed Brad’s guide for deploying Django. I kinda got it to run but the static files (CSS, JS and images) are not being served. It's an issue with my configuration and it is not clear to me what I'm doing wrong here or what exactly I am missing. Here is what the end result it should look like: Here is what mine actually looks like: Exploring other questions and answers on SO, inside my settings.py, I've tried swapping in (and out) different paths into STATIC_ROOT, MEDIA_ROOT, STATICFILES_DIRS using the join method. I’ve also tried adding a number of different list items into the urlpatterns variable inside urls.py. After trying each new potential change, I enter python manage.py collectstatic and then I run the server. Sometimes there would be a trace back preventing the server from running. In these situations, I just rolled back the change to a setting which was known to work or alternatively, I just tried something else entirely which would enable the server to run without a trace back. Here are some of the other questions on SO which I … -

Modal form not submitting Django
I have a modal which does not submit. I'm using the Django base model. I think it could be a problem with the CSRF token since it's been throwing that error.

TemplateDoesNotExist on Django custom management command tests
I have the following custom management command: from django.template.loader import render_to_string from django.core.management.base import BaseCommand class Command(BaseCommand): args = "" help = """Validates models.""" def handle(self, *args, **options): ... message = render_to_string( "validation_email.html", context ) ...

However, when I try to test it with the following test case: from io import StringIO from django.core import mail from django.core.management import call_command from django.test import TestCase from my_app.management.commands import validate_models class TestValidateModels(TestCase): def test_successful_call(self): out = StringIO() cmd = validate_models.Command() call_command(cmd, stdout=out) self.assertEqual(len(mail.outbox), 1) It gives me the following error: django.template.exceptions.TemplateDoesNotExist: validation_email.html Am I missing something? Why the command works just fine from the command line, but generates template problems while running unit tests? Is there any tweak needed about the templates to be able to test Django custom management commands? -

Showing related instance on readonly popup in django admin
When you see the control (e.g. a dropdown) for a related field in a Django admin create/edit form for a Model, by default it comes with 2 icons, one for add a new instance and one for editing the selected instance. I know that the formfield's widget can be tweaked with the can_add_related and can_change_related flags to not show those icons, but I wonder: is there any out-of-the-box way to have a "view" icon that would display a pop-up just like the edit one but with all fields being displayed as readonly? (There's a can_view_related flag, but that's not what it's for) So far the "easiest" way I can think of is extending the admin/change_form.html template and seeing if I can somehow force all controls to be readonly when is_popup is set to true. -
AttributeError: 'NoneType' object has no attribute 'split' in Firefox only
I have recently started a project in Django and I don't have too much experience in this framework. However, everything is working fine so far, but I am getting these errors when I open the project's site in the browser. I am not sure what it is about, but I have noticed that this happens only in Firefox and only after opening any other site (particularly in my case Facebook or Gmail) in new tab, while navigating to any page on my project. Prior to the visit of these websites, everything is working fine without any error in the console. If I clear the cache of the browser after this happen and close the additional tabs, everything is back to normal until I reopen any of the websites again. Also, I have checked if this would be a case in Chrome and I have noticed that everything is working fine there, even when the mentioned websites are opened in new tab. Can anyone provide me more information on what would be the reason for these errors?

django: how to download a dataframe that is returned from a view
I have a form that takes an api key and an id and retrieves some data with a "load" button. That data is served as html in a template. Once the user sees the data that was retrieved, I would like them to be able to download the data as a CSV file by clicking a "download" button. What I've been trying to do is pass data as a context variable into a template, and then send that data on to another view that returns a download response from a view called "export". Perhaps there's a better way to do this? Sorry if this is a really dumb question. views.py def myview(request): if request.method == 'POST': # create a form instance and populate it with data from the request: form = WorkbenchForm(request.POST) # check whether it's valid: if form.is_valid(): context['form'] = form # Retrieve data from api [...] context['data'] = pandas_dataframe.to_html() context['file'] = pandas_dataframe.to_csv() return render(request, 'app/data.html', context) def export(request): response = HttpResponse(request, content_type='text/csv') response['Content-Disposition'] = 'attachment; filename=' + 'test.txt' return response data.html <body> <h1>Data</h1> <form action= "" method="post"> {% csrf_token %} {{ form.as_ul }} <input type="submit", value="Load"> </form> {% if data %} <h4>Data</h4> {{ data | safe }} <form … -

What is the django rest framework suggested way, to render a serializer html template using Response() with Class Based View?
I'm defining a Class based view CRUD using Response() method, where I need to return my serialized data to a html template, but I haven't found a functional example using CBV (class based view) instead of FBS (function based view). I have read the DRF documentation about viewsets, requests and Response, and I found some ways to do that, but I'm not sure what is best suggested way according to my context. My project structure is as below: api core fixtures logs static templates users web In api folder I have my serializer and my api class: serializers.py class CustomDictionarySerializer(serializers.ModelSerializer): class Meta: model = CustomDictionary fields = ('__all__') api.py class CustomDictionaryViewSet(viewsets.ModelViewSet): queryset = CustomDictionary.objects.all().filter( is_active=True, is_deleted=False ).order_by('id') permission_classes = [ permissions.AllowAny ] serializer_class = CustomDictionarySerializer pagination_class = StandardResultsSetPagination urls.py router.register('api/customdictionary', CustomDictionaryViewSet, 'customdictionary') Then, in my web folder, I needed to render my serialized data, so I tried as below: views.py class CustomDictionaryView(View): def get(self, request, *args, **kwargs): queryset = CustomDictionary.objects.all() serializer = CustomDictionarySerializer(self.get_queryset, many=True) return Response(serializer.data,status=status.HTTP_200_OK,template_name='web/dictionary_get.html') ...

How to get all related objects from a reverse foreign key Django serializer (one-to-many)?
I have been trying to create a Trello-like clone and storing my 'Lists' and 'Applications' as separate models with a foreign key on my 'Applications' model to create a One-To-Many between Lists and Applications. I usually use Node and Sequelize and have been unsuccessful in trying to query my Lists and also returning all the Applications with the List's ID as the Applications foreign key. I suspect I am just missing something silly on my Serializers. I've tried a few things that broke the code, but now I just have it returning the List's fields like this: [ { "title": "My First List" }, { "title": "My Second List" }, ] when in reality what I really want back is something like: [ { "id": 1, "title": "My First List", "applications": [ { "id": 1, "company_name": "Spotify", "position": "Web Engineer", "date_applied": "2019-09-09", "application_id": "xv112_cv", "priority_level": "High", "company_contact_email": "jg@spotify.com", "notes": "Seems promising", "location": "New York", "status_list": "1" }, { "id": "2", "company_name": "Foursquare", "position": "Client Solutions Engineer", "date_applied": "2019-10-09", "application_id": "fsq_app_1", "priority_level": "High", "company_contact_email": "jdwyer@foursquare.com", "notes": "Interview on 9/29/19", "location": "New York", "status_list": "1" }, ] }, { "id": "2" "title": "My Second List", "applications": "applications": [ { "id": "3", "company_name": … -
How do I automate this sendinblue api?
Trying to automate the adding of contacts to sendinblue's api. The example given on their site shows adding a email and then adding it to a list in your account. I have tried fstrings and .format(email, industry, role) but for some reason it keeps throwing back errors. Heres what their website shows which works. import requests url = "https://api.sendinblue.com/v3/contacts" payload = "{\"email\":\"someonesEmail97@gmail.com\",\"listIds\":[1,4],\"updateEnabled\":false}" headers = { 'accept': "application/json", 'content-type': "application/json" } response = requests.request("POST", url, data=payload, headers=headers Here's what I tried import requests url = "https://api.sendinblue.com/v3/contacts" payload = "{\"email\":\f"{email}"\",\"listIds\":[f"{industry}",f"{role}"],\"updateEnabled\":false}" headers = { 'accept': "application/json", 'content-type': "application/json" } response = requests.request("POST", url, data=payload, headers=headers) I want this in the signup part of my site so it will grab their email thats been authenticated and add it to the appropriate list that I have set up. But what I get back from using fstrings is invalid syntax in the terminal pointing to the email field. I then tried .format and that didn't show any errors on the terminal but on the webpage I got this error back payload = "{\"email\":\{}\",\"listIds\":[{},{}],\"updateEnabled\":false}".format(email, industry, role) KeyError at /accounts/signup/activate/ "'email'" points to line that the payload is on.
