Searching for JSON in Django
I was able to import my data.json into Django after some time. Right now when a request is sent, the view.py function spits out the whole data.json file. I want to create a view.py function that only returns the results of a search request that was submitted and not the whole data.json. If I search for apple, I want the definition for apple to be returned from within data.json. I don't even know what I need to do. Do I convert the data.json file into SQL or python dictionary? Do I convert data.json into a model? The data.json files doesn't specify keys or values. views.py def searchbar(request): if request.method == 'GET': file_path = os.path.join(os.environ.get('HOME'), 'data.json') with open(file_path, 'r') as f: context = {"file_path": f} return render(request, 'movies/searchbar.html', context) searchbar.html {%block content%} {% for i in file_path %} {{i}} {%empty%} There is nothing here {%endfor%} {%endblock content%} home.html <form action ="{% url 'searchbar' %}"method="get"> <input type="text" name="search"/> <button type="submit"> Search</button> </form> data.json contents in searchbar.html when search is pressed: -

Django forms not returning result or errors
I am trying to use a Django form for a login page, but the form is returning False whenever I call form.is_valid(). I tried to print the errors in the console and in the HTML file but there's nothing displaying. I tried to get data from the form with form["email"].value() and it's returning None, even when I input data into the email field. Here's views.py: def postlogin(request): form = BootstrapAuthenticationForm(request.POST) # This prints out None into the console print(form["email"].value()) if form.is_valid(): # This code never runs! Even when there are no errors in the form fields! return render(request, "app/home.html") # If form is invalid, return to login page # This always runs, meaning form.is_valid() keeps being false! return render(request,"app/login.html", {"form":form}) Here's my forms.py: from django import forms from django.contrib.auth.forms import AuthenticationForm from django.utils.translation import ugettext_lazy as _ class BootstrapAuthenticationForm(AuthenticationForm): """Authentication form which uses boostrap CSS.""" email = forms.CharField(max_length=254,label=('Email'), widget=forms.TextInput({ 'class': 'form-control', 'placeholder': 'Email'})) password = forms.CharField(label=("Password"), widget=forms.PasswordInput({ 'class': 'form-control', 'placeholder':'Password'})) Here's my login.html: {% extends "app/layout.html" %} {% block content %} <h2>{{ title }}</h2> <div class="row"> <div class="col-md-8"> <section id="loginForm"> <form action="/postlogin/" method="post" class="form-horizontal"> {% csrf_token %} <h4>Use a local account to log in.</h4> <hr /> <div class="form-group"> <label for="id_username" … -
Why Django Messages Won't Work for logout but it work for my sing up?
I wrote this code: my view: from django.contrib.auth.views import LoginView, LogoutView class CustomLogout(LogoutView): def post(self, request, *args, **kwargs): messages.success(request, 'Logout was successfully') return super(CustomLogout, self).get(request, *args, **kwargs) This is my url: urlpatterns = [ ... path('logout/', CustomLogout.as_view(template_name='core/index.html'), name='logout'), ] and I have this in my template: {% if messages %} <div class="alert alert-dismissible" role="alert"> {% for message in messages %} <div class="alert alert-{{ message.tags }}">{{ message }} </div> {% endfor %} </div> {% endif %} I write something like this for SignUp and it works well and show the messages but in this case for logout it won't show any message in template... -

Suitescript that attempts to set an amount for sales order items causes "unexpected error"
I have this code that, in theory, changes the amount on the sublist of a sales order in Netsuite, but for one reason or another it tells me that an unexpected error happened.

Query to calculate user balances
In my project there are coins that users can buy, use to perform certain actions and convert to real money. A user can only convert coins earned (by receiving gifts for example) into real money, not those bought from the site directly. Therefore, two balances are calculated internally: coins bought and coins earned (the total balance is the sum of these two). The following model contains coin transactions (it's simplified): class CoinTransaction(models.Model): class TransactionTypes(Enum): purchase_of_coins = ('pu', 'Purchase of Coins') # Will have a positive amount conversion_into_money = ('co', 'Conversion Into Money') # Will have a negative amount earning = ('ea', 'Earning') # Will have a positive amount expense = ('ex', 'Expense') # Will have a negative amount @classmethod def get_value(cls, member): return cls[member].value[0] user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.PROTECT, related_name='coin_transactions') amount = models.IntegerField() transaction_type = models.CharField(max_length=2, choices=[x.value for x in TransactionTypes]) The earned coin balance is increased by all income except coin purchases, while the bought coin balance is increased only by coin purchases. Coins from conversion_into_money transactions are subtracted from the earned coin balance, while all other expenses are first subtracted from the bought coin balance if greater than 0. Note that the two balances cannot go below 0. To … -
Django filters just returns all objects
So I have model like this class Research(models.Model): CATEGORIES = (...) name = models.CharField(max_length=80) date = models.DateField() category = models.CharField(max_length=10, choices=CATEGORIES) public_use = models.CharField(max_length=17, choices=PUBLIC_USE_CHOICES) This filter: class ResarchFilter(filters.FilterSet): year = filters.DateFilter(field_name='date', lookup_expr='year') category = filters.CharFilter(field_name='category', lookup_expr='iexact') class Meta: model = Research fields = ['date', 'category'] And that view: class ResarchCategoryYear(generics.ListCreateAPIView): queryset = Research.objects.all() serializer_class = ResearchSerializer filter_backends = (filters.DjangoFilterBackend,) # filterset_fields = ['date', 'category'] filter_class = ResarchFilter So when I'm uncomment filterset_fields and comment filter_class it all works well but I can't filter by the year and not by the full date. So when I'm do it like in code above and goes to http://127.0.0.1:8000/...?year=2000 It literally do nothing, just gives me all of the Research objects. So what I'm doing wrong and how to enable this filtering? -

Performance: Best way to send large amounts of data
On my website, users can upload posts with or without files (images, audios, videos, etc.) to the database. I have two options now: Send a very large request containing the posts data as well as maybe multiple GB of data. Then create a post object and connect the files to it. Send one very small request with only the content of the post and creating one in the backend. Then sending back the UUID to the post. Then automatically sending a large request containing the files & the UUID to the backend and connecting post & files afterwards. The pro (at least IMO) to the second solution is that users could already see their posts while the files are still being processed by the backend celery worker. Would this be considered bad or good user experience? Not sure how well both solutions might scale in the future and if it'd be a difference in traffic load when there's two requests being sent. -
How to use JavaScript client-side encryption/decryption in django forms / crispy forms? Is there any python package available which can do this
Django Form fields needs to be encrypted at server side and needs to be decrypted in client browser while rendering and vice versa for form submission One approach is using JS cryptographic libraries or to use custom encryption code. But, Is there any python package available which implements this where we use this as django form widget along with js library at client side. An example will be a package like the django-autocomplete-light package which provides a widget for autocompletion for the particular field. How to implement this or Is there any package available which can be used. -
Django: in views how can a redirect if the paramater(linked to a url pattern) does not match a model result?
I apologize am still learning django and am just hitting my head on a wall with some of it. The current issue is that I have a view linked through a URL parameter the issue and it works for showing my model info but if you hard type the url to a different parameter it shows the page. I have tried to redirect it but that is not working I feel like it might because of how and where I return my render. Any advice on how to set up url's base off model and if that model info doesn't exist either through a 404 or redirect to a different page?

requests are working locally but not on Heroku. Getting internal server error 500 and JSON not valid
I built a web application with django and react. It is working perfectly fine locally and the heroku deployment worked fine without issues. When I am testing the heroku app some of my requests are working fine like login/register. However the request where information is being sent back from the server to be displayed or post requests sending information are giving me the following error GET [request name] 500 (Internal Server Error) and Uncaught (in promise) SyntaxError: Unexpected token '<', "<!DOCTYPE "... is not valid JSON Would this issue be related to my requirements.txt or Procfile? Since the issue is not happening when the project is run locally and only on heroku. Could anyone point me in the right direction? -
