Add cropper js to django template
I am new to web development. I am trying to learn django. I have managed to come so far. I want my user to upload picture and also be able to crop the picture while uploading. I dont have any problem with img uploading but the results i found for croping is too advanced for me i dont know how to implement them. I have found below example made in django but still couldnt understand the way it works to be able to add to my own project. Any help is appreciated. Please explain to me like i am 5. I am very new to Jquery, css and everything except python. Thanks https://github.com/adriancarayol/django-cropperjs -
nginx serve both django static files and react static files
Im recently trying to impement nginx to link up my django based backend and react based frontend. Here is my nginx config file: upstream api { server backend:8000; } server { listen 8080; location /api/ { uwsgi_pass backend:8000; include /etc/nginx/uwsgi_params; } location /admin/ { uwsgi_pass backend:8000; include /etc/nginx/uwsgi_params; } # ignore cache frontend location ~* (service-worker\.js)$ { add_header 'Cache-Control' 'no-store, no-cache, must-revalidate, proxy-revalidate, max-age=0'; expires off; proxy_no_cache 1; } location / { root /var/www/frontend; try_files $uri /index.html; } location /static { alias /vol/static; } location /static/rest_framework/ { alias /vol/static; } } However, the issue is that my manage.py collect static will place the django static files into /vol/static however, my react build is in /var/www/frontend/ therefore when I try accessing the default / url, it returns a blank page. However, if i remove the location /static { alias /vol/static; } location /static/rest_framework/ { alias /vol/static; } It will serve my my django admin page without any css. How do i resolve this easily without putting both static files in the same directory? -
Heroku: R15 Error Memory quota vastly exceeded when loading large files
So I am new at deploying Heroku applications. I have built a django application that basically reads from a Machine Learning model (1.3GB). This model is stored as a variable via the pickle.load function: model = pickle.load(url_path) I need this model to be accessed frequently in the application. For example, each user has a the possibility to do a prediction over some stocks. When he uses the prediction functionality we will do basic operations on this ML model. After deploying the django application via Heroku, I receive the Heroku: R15 Error Memory quota vastly exceeded, that corresponds in time with the 'model=pickle.load(url_path)' operation. I believe it is expected since the model that will be stored as variable is 1.31GB and the dyno used has 512MB. I would need a way to use this variable frequently (maybe through a third party or anything else) without having to upgrade to Advanced/Enterprise dynos. This would be really appreciated. Kind regards, Marvin -
Struggling to get Django server to run in virtual environment
I'm new to using Django & Python and am having some difficulty trying to get my manage.py application to run in a virtual environment. I am receiving the following errors at the top of my models.py file: I initially thought that this was an issue with pylint not pointing at the right environment (when I switch my Python interpretter to the one outside of the virtual environment, the pylint errors disappear); however, whenever I try to run my server, I get the following error: (.venv) tjmcerlean@LAPTOP-RKLCBQLO:/mnt/c/Users/tjmce/Desktop/Git/CS50w/Project 2/commerce$ python manage.py runserverTraceback (most recent call last): File "manage.py", line 10, in main from django.core.management import execute_from_command_line File "/mnt/c/Users/tjmce/Desktop/Git/CS50w/Project 2/commerce/.venv/lib/python3.8/site-packages/django/__init__.py", line 1, in <module> from django.utils.version import get_version ModuleNotFoundError: No module named 'django.utils' The above exception was the direct cause of the following exception: Traceback (most recent call last): File "manage.py", line 21, in <module> main() File "manage.py", line 12, in main raise ImportError( ImportError: Couldn't import Django.

User filtering in Django, how to return specific user's data?
Been trying to figure this out for a long time(as in days), but can't understand what to use to return one users "events". A bit new and unfamiliar so would love any help I could get.

Django Translation (Translate Database Values)
I'm working on a project and they asked me to make the project multilingual. but they don't have specific languages, and I want to handle this in the simplest and smarter way so I thought if I use django-modeltranslation package it will be good for me. things to know: 1- there are a lot of fields that need to translate into a lot of models and columns. 2- I Im working on drf, the front end in another language. things to do : 1- I want to make dynamic serializers to handle the columns that contain translation. ex(name_en, name_fr, name_ar ...etc.) so the serializer should return the "name" key always, not "name_en" or "name_fr". I made some code and worked fine with me but it will be a headache for me and hard to cover all cases and fields that I need to translate. example code : models.py name = models.CharField(max_length=250, blank=True, null=True) translation.py from modeltranslation.translator import translator, TranslationOptions from .models import Category class CategoryTranslationOptions(TranslationOptions): fields = ('name', 'description') translator.register(Category, CategoryTranslationOptions) request_helper.py def check_language(language): if language: return language else: return "en" def check_accept_language_header(headers): is_lang = False if "Accept-Language" in headers.keys(): is_lang = True if is_lang: return check_language(headers["Accept_Language"]) else: return "en" … -
unique=True always raises exception when used with save(commit=False)
I have a model with two fields f1 and f2. f1 has a unique constraint. I have 2 ModelForms, MF1 and MF2, one for each field. In my view, I render & process the two ModelForms. is_valid() calls on both my_MF1 and my_MF2 are fine. When I save my_MF1.save(commit=False) my_MF2.save() I get a "UNIQUE constraint failed" exception on the second save call. The second call considers that the first one has already created a record with some f1 value. When I save my_MF2.save(commit=False) my_MF1.save() everything works fine. Is this the expected behavior or is this a bug? If it is not a bug, it would be impossible to have both f1 and f2 unique. I am using SQLite. -

The view is def news(request): """ Interface for newslist """ page = 1 if request.method == 'POST': content = request.body try: content = json.loads(content) except ValueError as error: return err_response("Value Error of post: {}".format(error)) if 'page' in content: page = content['page'] articlelist = Article.objects.all().order_by('-time') paginator = Paginator(articlelist, 10) try: current_list = paginator.page(page) except InvalidPage as error: return err_response(error) # coping with the paginator ... newsnum = len(Article.objects.all()) return JsonResponse({ 'newsnum': newsnum, 'pagelist': list(pagelist), 'data': [{ 'title': newsitem.title, 'source': newsitem.source, 'time': newsitem.time.strftime("%Y-%m-%d %H:%M:%S"), 'content': newsitem.content, 'href': newsitem.href, 'image': newsitem.image, } for newsitem in current_list] }, status=200) When I use pytest-django to test it @pytest.mark.django_db def test_view_news(client): """ Test view news """ url = reverse("news") data = { 'page': 1 } response = client.post(url, data=data) assert response.status_code == 200 It gives Bad Request and code 400. But when I use client.get(), the response is normal (code 200).In the settings, I already set DEBUG = True ALLOWED_HOSTS = ['*'] Can anyone tells me what happened? -
How to Django reverse to pages created in Wagtail?
I have a Wagtail model for an object. class ObjectPage(Page): # fields, not really important I want to make the object editable by front-end users, so I have also created a generic update view to accomplish this. My question is how I can use Django's reverse() function to point to the edited object in my get_success_url() method: class EditObjectPage(LoginRequiredMixin, UpdateView): # model, template_name, and fields defined; not really important def get_success_url(self): return("ObjectPage", kwargs={"slug" : self.object.slug}) # doesn't work return("object_page_slug", kwargs={"slug" : self.object.slug}) # also doesn't work I know how to do this when I'm explicitly defining the URL name in my urls.py file, but in this case, the URL is created as a Wagtail page and is handled by this line of my urls.py: url(r"", include(wagtail_urls)), I've been searching the documentation for whether Wagtail pages are assigned names that can be reversed to, but I'm finding nothing in the official documentation or here on StackOverflow. -
Django How to add data to database from javascript
I am have created a page in django, on this page I have create a button that calls a JavaScript function which in turn gets data from a API. This part of my code works as expected as it writes the response data to the console. However I cannot seem to get that data to be inserted into the model I have created in django. I am not sure how python/javascript/models are meant to all link together. models.py from django.db import models class Set(models.Model): scry_id = models.CharField(max_length=255) code = models.CharField(max_length=255) name = models.CharField(max_length=255) set_type = models.CharField(max_length=255) release_date = models.DateField() card_count = models.IntegerField() block_code = models.CharField(max_length=255, null=True) block_name = models.CharField(max_length=255, null=True) parent_set_code = models.CharField(max_length=255, null=True) digital_only = models.BooleanField(default=False) foil_only = models.BooleanField(default=False) nonfoil_only = models.BooleanField(default=False) icon = models.CharField(max_length=255) status = models.BooleanField(default=False) def __str__(self): return self.name sets.html {% extends "main/index.html "%} {% block content %} <div class="background card"> <div class="card-body"> <button class="btn" id="setRefresh" style="border: 1px solid" onclick="setRefresh()"><i class="fas fa-sync"></i></button> </div> </div> {% endblock%} custom.js function setRefresh() { const Url="https://api.scryfall.com/sets"; fetch(Url) .then(res => res.json()) .then(data => obj = data.data) .then(() => obj.sort(function(a,b){return a.released_at.localeCompare(b.released_at);})) .then(() => { for (var i = 0; i < obj.length; i++) { //console.log(obj[i].name); } }) } -

Apply DRY to a dict where data is coming from different vars
I have two functions where I pass the dict event_data = {[...]} to the Google API. The only difference is that for update_calendar_event the data is coming from a dict. For create_calendar_event it is an obj. Do you have any idea how to apply DRY here while considering that it's these two different types? class GoogleCalendarAPI: def __init__(self) -> None: # cache_discovery=False to avoid ImportError self.service = build( "calendar", "v3", credentials=credentials, cache_discovery=False ) def _event_link(self, event_slug: str) -> str: return "https://example.com/events/" + event_slug def update_calendar_event( self, calendar_event_id: str, validated_data: Dict[str, Any], event_slug: str ) -> None: event_data = { "summary": validated_data.get("name"), "description": validated_data.get("description") + "\n\nEvent link: " + self._event_link(event_slug), "start": { "dateTime": validated_data.get("start_date").isoformat(), "timeZone": validated_data.get("timezone"), }, "end": { "dateTime": validated_data.get("end_date").isoformat(), "timeZone": validated_data.get("timezone"), }, } self.service.events().patch( calendarId=CALENDAR_ID, eventId=calendar_event_id, body=event_data ).execute() def create_calendar_event(self, event_instance) -> str: event_data = { "summary": event_instance.name, "description": event_instance.description + "\n\nEvent link: " + self._event_link(event_instance.slug), "start": { "dateTime": event_instance.start_date.isoformat(), "timeZone": event_instance.timezone, }, "end": { "dateTime": event_instance.end_date.isoformat(), "timeZone": event_instance.timezone, }, } event = ( self.service.events() .insert(calendarId=CALENDAR_ID, body=event_data) .execute() ) return event.get("id")
