Django DATE_FORMAT weekday name
I want to format date object in Django. Specifically, I want to use DATE_FORMAT in settings.py. Using Django Documentation, I set it as: DATE_FORMAT = 'l, m F Y'. Lowercase l means weekday name. In the template I use {{ value|date:"DATE_FORMAT" }}, but it never renders the weekday name. If I do the: {{ value|date:"l, m F Y" }}, I get the results expected. Are there any limitations which built-in date filters are allowed in settings.py? Thank you! -

Django server and android not communicating correctly
Django Server and Android are not communicating correctly. In the test code, the onMassage method executes correctly when the websocket.send () method is executed. But if you change the url, after onOpen () is executed, it goes directly to onClose () without going through onMassage (). import android.os.Bundle; import android.util.Log; import android.view.View; import android.widget.Button; import android.widget.TextView; import androidx.appcompat.app.AppCompatActivity; import okhttp3.OkHttpClient; import okhttp3.Request; import okhttp3.Response; import okhttp3.WebSocket; import okhttp3.WebSocketListener; import okhttp3.logging.HttpLoggingInterceptor; import okio.ByteString; public class MainActivity extends AppCompatActivity { private Button start; private TextView output; private OkHttpClient client; private final class EchoWebSocketListener extends WebSocketListener { private static final int NORMAL_CLOSURE_STATUS = 1000; @Override public void onOpen(WebSocket webSocket, Response response) { webSocket.send("Hello, it's SSaurel !"); webSocket.send("What's up ?"); webSocket.send(ByteString.decodeHex("deadbeef")); webSocket.close(NORMAL_CLOSURE_STATUS, "Goodbye !"); } @Override public void onMessage(WebSocket webSocket, String text) { Log.e("asd", "on message"); output("Receiving : " + text); } @Override public void onMessage(WebSocket webSocket, ByteString bytes) { Log.e("asd", "on message"); output("Receiving bytes : " + bytes.hex()); } @Override public void onClosing(WebSocket webSocket, int code, String reason) { Log.e("asd", "on closing"); webSocket.close(NORMAL_CLOSURE_STATUS, null); output("Closing : " + code + " / " + reason); } @Override public void onFailure(WebSocket webSocket, Throwable t, Response response) { Log.e("asd", "on fail"); output("Error : " + … -
Django: presave signal to get file extension in Model
In Django, for file field, its possible to use callable for example user_directory_path in the code below. def user_directory_path(instance, filename): # file will be uploaded to MEDIA_ROOT/user_<id>/<filename> return 'user_{0}/{1}'.format(instance.user.id, filename) class MyModel(models.Model): upload = models.FileField(upload_to=user_directory_path) extension = models.CharField(max_length=100, null=False, blank=False, default=get_filename_ext) However, for the extension field I want to use the get_filename_ext function so that extension of the file gets saved. def get_filename_ext(filepath): base_name = os.path.basename(filepath) name, ext = os.path.splitext(base_name) return name, ext Is there something similar in Django model? Or do I have to do this in Django view? -

I have two forms named GoodAtForm and PaidForForm. What these do is as follows... GoodAtForm Takes an input from a list in request.session['love'] and presents it to the user. Then user is presented with a CheckboXSelectMultiple fields so that users can select. After The form is submitted in the view, the user choices are then stored inside another list request.session['good']. 4.Another Form named PaidForForm uses that list for further asking of questions from users using CheckBocSelectMultiple and the selections are from the list ```request.session['good']. My problem is that I am unable to access output data inside the Forms to provide it to view. Input is working fine when initialised. My forms renders from the given list but the problem is that Form is not providing output. It says 'QueryDict' object has no attribute 'session' This is my GoodAtForm class GoodAtForm(forms.Form): def __init__(self, request, *args, **kwargs): super(GoodAtForm, self).__init__(*args, **kwargs) input_list = request.session['love'] self.fields['good'] = forms.MultipleChoiceField( label="Select Things You are Good At", choices=[(c, c) for c in input_list], widget=forms.CheckboxSelectMultiple ) View For the GoodAtForm def show_good_at(request): if request.method == 'POST': form = GoodAtForm(request.POST) #it is showing problem here. Throws an exception here if form.is_valid(): if not request.session.get('good'): request.session['good'] = [] request.session['good'] = …
