GET http://localhost:8000/add/ Page not found
I've been working on this application using my localhost:8000 for a while now and everything had been working smoothly. However now that I have tried to add a new url: /add/. For some reason it doesn't recognise the URL. I believe maybe there's something wrong with how I've wrote my code but I haven't quite found it. Any help would be great! To provide context I started of in my urls.py file where I created a new path: path('add', views.ProjectCreateView.as_view(), name='add'), I then moved over to my views.py file and imported the CreateView as so: from django.views.generic import CreateView. From there I then created a class for the view: class ProjectCreateView(CreateView): model = Project template_name = 'budget/add-project.html' fields = ('name', 'budget') Following this I then created another file within my budget folder nested in my templates folder. The file name add-project.html. I don't think there's anything wrong with this file but just to guarantee this is how I linked my html file: {% extends 'budget/base.html' %} {% load static %} {% block content %} This is the exact message I get when I run http://localhost:8000/add/ "No Project matches the given query." -
Running celeryd-worker on elastic-beanstalk
I am trying to get celery set up on elastic-beanstalk to run periodic-tasks. I have gotten everything running except for the celeryd-worker on elastic-beanstalk.

How to load master data (stored in DB) in client pages effectively?
I have a web application (built in Angular1.X and Django) that displays 6 product information (master data) stored in database. This information does not change by any transaction or action in my application, but will be referred in processing user actions. In order to increase the speed of my application page load, I’m trying to find an effective method to quickly access these information in different pages. I know the following are a few of the options to access this information every time. 1) Store the product details in local or session storage at client side for every page load and refer those values from that storage memory 2) Make a call to server to get these information as and when required at client side Is there any other option to store these master data at client side file or other means once at the time of production server start up and use that information for every time page loading? -
Django View: Return Queryset in JSON Format
i am trying to make the following view with return JsonResponse() at the end work correctly: def get_data(request): full_data = Fund.objects.all() data = { "test2": full_data.values('investment_strategy').annotate(sum=Sum('commitment')), } return JsonResponse(data) However, I get an error message saying "Object of type QuerySet is not JSON serializable". When I put the above Queryset in a view with return render() at the end: def get_more_data(request): full_data = Fund.objects.all() data = {"test2": full_data.values('investment_strategy').annotate(sum=Sum('commitment'))} return render (request, 'test.html', data) I get the the following result: <QuerySet [{'investment_strategy': 'Buyout', 'sum': 29}, {'investment_strategy': 'Growth', 'sum': 13}, {'investment_strategy': 'Miscellaneous', 'sum': 14}, {'investment_strategy': 'Venture Capital', 'sum': 23}, {'investment_strategy': 'n/a', 'sum': 36}]> So the queryset works fine, I just have no clue how to return the data in proper Json format (which I would need to use the data charts.js) I looked through answers for similar questions such as: TypeError: object is not JSON serializable in DJango 1.8 Python 3.4 Output Django queryset as JSON etc. but could not find a meaningful solution for my problem. Any help would be much appreciated! -
How to fix 'min() arg is an empty sequence' python+couchdb error
I have to do mosaic application in Python using Django and Couchdb, which are kind of new to me, for my studies. In part where I'm trying to do the mosaic, I got ValueError at 'min' function. However I run out of ideas why it is not working. I read the couchdb docs, reach some friends who already know a little python. rgb_of_tile = list(tile.getdata()) rgb_of_tile_list = utils.get_average_rgb_as_list(rgb_of_tile) returned_tiles = get_tiles(rgb_of_tile_list) closest = min(returned_tiles, key=lambda c: ( (rgb_of_tile_list[0] - c['key'][0]) ** 2 +(rgb_of_tile_list[1] - c['key'][1]) ** 2 + ( rgb_of_tile_list[2] - c['key'][2]) ** 2)) Error occurs on variable 'closest', but when I looked at the error I saw that 'returned_tiles'=[ ]. Below is code for that variable. I don't really know why it is not working, as the CouchDB reference-'tiles_url' should work properly def get_tiles(rgb_of_tile_list): rgb_of_tile_start = [x.__sub__(10) for x in rgb_of_tile_list] rgb_of_tile_finish = [x.__add__(10) for x in rgb_of_tile_list] tiles_url = "http://images_db_user:pass@localhost:5984/images/_design/view/_view/new-view?start_key=" + str( rgb_of_tile_start) + "&end_key=" + str(rgb_of_tile_finish) + "&include_docs=true" response = requests.get(tiles_url).json() returned_tiles = response['rows'] return returned_tiles -
Django/DRF - REST API endpoint with query parameter that goes queries multiple endpoints
Hey guys I'm having some trouble trying to architect how this endpoint would work. Currently I would like this endpoint "/nba/players?date=01012016" to work by going two different endpoints for results. Currently my GameDates endpoint returns something similar to {id: 1, home_team_id: 1, away_team_id: 2, date: "1/1/2016"}, {id: 4, home_team_id: 2, away_team_id: 3, date: "1/2/2016"} I want to grab that GameDate_id or it's primary key (in this case id:1) which then gets passed on to a another PlayerStatistic endpoint which will return something like this - {id: 1, game_id: 1, player_id: 1, team_id: 1, points: 20, assists: 10, rebounds: 2}, {id: 2, game_id: 1, player_id: 2, team_id: 1, points: 15, assists: 2, rebounds: 2}, {id: 3, game_id: 1, player_id: 3, team_id: 2, points: 10, assists: 2, rebounds: 20}, {id: 4, game_id: 1, player_id: 4, team_id: 2, points: 5, assists: 1, rebounds: 2} My initial endpoint with the date query would return these four JSON since a player had a game on that date (game_id = 1) from the GameDate endpoint, then that game_id gets used to query the PlayerStatistic endpoint and returns. I know the right method of say overriding the get_queryset function something like - def get_queryset(self): date = self.request.query_params.get('date') … -

django 2.2.5 import url from one app to another app
I would like to use the url from products app (products/urls.py) inside of search app url (search/urls.py) to search for items/products using search bar.

Django-crispy-forms: set css for individual field and inputs

What is the command to search a content in all the model fields at once?
I am developing an app with Django. I have developed a search bar to filter the database contents. I want that, when the user clicks on the search button, the indicated content is searched in all the model fields. My model has 16 fields, so my filter command will be a very long line, like: selected_entries = glossary_entry.objects.filter(Q(field1__icontains=query) | Q(field2__icontains=query)) | ...ETC ETC... | Q(field16__icontains=query)) Here you can see this line in my view function, in views.py: def glossario(request): query = request.GET.get('q') template = "glossario.html" # query applied if query: query = request.GET.get('q') selected_entries = glossary_entry.objects.filter(Q(field1__icontains=query) | Q(field2__icontains=query)) | ...ETC ETC... | Q(field16__icontains=query)) return render(request, template, {'all_entries':selected_entries}) # no query else: all_entries = glossary_entry.objects.all return render(request, template, {'all_entries':all_entries}) Is there a shorter command to do the same? Like: selected_entries = glossary_entry.objects.filter(Q(ALL_MODEL_FIELDS_ICONTAINS(model=MyModel)=query)) Note: ALL_MODEL_FIELDS_ICONTAINS is my invention -
How to display and save mutiple instances of a django form based on variable amount?
I've been looking around the site and can't seem to find an answer. Same for the django docs. The issue is I can't seem to save multiple instances of the same form. I'm trying to have a user set up a weekly calendar for a sports club. They land on a page with check boxes of each day they have activities. So if they click monday, tuesday, wednesday. Three instances of the DAY model are created created. Which works fine. Then, on the next page. Based on the amount of Days they have chosen, I would like a PeriodsForm (for this example let's just say they have one period each day). Then they can set what time each day starts and finises. I just can't seem to save the data. I was hoping someone has come across this before. Many thanks. I've tried using the modelformset_factory() but it's far too rigid. I also tried prefixes but I can't seem to loop through the forms on the POST. ### views.py def create_timetable_days(request): club = request.user.club form = TimetableCreateForm(request.POST or None) if len(list(Day.objects.filter(club=club))) > 0: return redirect('/timetables/create_timetable_times') if form.is_valid(): for item in form['Days']: if item.data['selected']: day = Day(name=item.data['label'], club=club) day.save() return redirect('/timetables/create_timetable_times') … -

Django Rest Framework - Group data by dynamic Key

I don't understand how to create my arrays properly using those serializers. The category is a @Property field in my model who's a foreign key of job. How should I deal with serializers to format my data properly ? -

Filter/order django rest api on a property=value but property is a value instead of a field
Consider an object that has multiple properties. class Object(models.Model): name= Charfield(max_length=80) class Property(models.Model): object= ForeignKey(Object, related_name='properties') name= Charfield(max_length=80) value= Charfield(max_length=80) I would like to provide an api accessible listview for the Object model, but I'm failing at ordering the ObjectList by property value as well as at sorting the the ObjectList by property value. To make the example more tangible you can imagine that Object has as type book, and an object of book has, among other properties, a property with name title and a value such as 20,000 Leagues Under the Sea. I would like to be able to be able to specify ?order_by=title and to be able to filter ?title__contains=League (or at least ?title="20,000 Leagues Under the Sea". I already did try to annotate Object with title="20,000 Leagues Under the Sea" and I'm able to show the title in the ObjectSerializer as if it was a field, but then ordering by this field does not work.
