But I want to use HTTPS.. any idea how to use it in EC2 Instance? -
Docker volume does not consistently update code
I am running a web server in docker container with the code mounted as a volume. I start the development server using docker-compose. In one of the server's Python files, I've put the following line that is executed on every refresh: print('1') After building it, it works fine. If, however, I change it to: print('2') without rebuilding, I expect to get '2' printed consistently but I get 1 and 2 printed randomly every refresh until I restart. Is this expected behavior? I don't want to restart the container each time I make a change. What would be the best solution for development? I am using IntelliJ PyCharm Professional Edition. version: '3' volumes: app: static: services: python_web_server: &python_web_server build: context: . dockerfile: python/Dockerfile volumes: - ../app:/app - ../app/static:/static command: bash -c "cd /app && gunicorn -w 4 webapp.wsgi -b 0.0.0.0:8000" depends_on: - rabbitmq - celery_worker -

Wrapping a BlockFeature in Draftail (Wagtail Rich Text Editor)
I am stuck at a problem. Maybe someone of you does have an Idea. The Problem looks like following: We have in Wagtail for the Draftail Editor 2 possible Features. Which are BlockFeature and InlineStyleFeature. But what, if you want to add a Feature in the Rich Text Editor, which should wrap an BlockFeature? As example: H1,H2,H3 etc. are BlockFeatures. I have done an custom Feature which will highlight stuff with an border, i did that with the InlineStyleFeature. So, this works properly on normal plaintext. But when you are adding some BlockFeatures like a H1 or a H2 the InputStyleFeature will automatically wrap inside the other Block Features. Example: Without Border: Some Plain Text <h1> Test </h1> With Border: <border> Some Plain Text <h1><border> Test </border> </h1> </border> The thing i want to accomplish is a simple : <border> Some Plain Text <h1> Test </h1> </border> When i am using a Border as a BlockFeature, the Headline Tags and all other BlockFeatures will be gone logically. So.. my question is : Is there any way to accomplish something like that ? Does anyone has experience with that kind of stuff? I would be happy if someone could help me. … -
Django models, dealing with multiple foreign keys
I'm busy dealing with datasets based on Freshwater Lakes in the USA. So my models are basically State and Lake. State being a foreign key in Lake. As I started loading data, I quickly realised that it appears that some Lakes are bordering multiple states. Example Lake Erie goes into 4 states + an international border. I then had to rethink my models a bit and came up with the following, class State(models.Model): name = models.CharField(max_length=200, null=True) def __str__(self): return str(self.name) class Lake(models.Model): state = models.ForeignKey(State, on_delete=models.CASCADE, verbose_name="primary state", related_name="related_primary_state", help_text="Primary State") state_secondary = models.ForeignKey(State, on_delete=models.CASCADE, null=True, blank=True, related_name="related_secondary_state", verbose_name="secondary state", help_text="Secondary State") state_three = models.ForeignKey(State, on_delete=models.CASCADE, null=True, blank=True, related_name="related_three_state", verbose_name="three state", help_text="three State") state_four = models.ForeignKey(State, on_delete=models.CASCADE, null=True, blank=True, related_name="related_four_state", verbose_name="four state", help_text="four State") state_five = models.ForeignKey(State, on_delete=models.CASCADE, null=True, blank=True, related_name="related_five_state", verbose_name="five state", help_text="five State") name = models.CharField(max_length=200, null=True) def __str__(self): return str(self.name) Would this be okay to do, or are there better ways to approach this? Thanks! -

How to see the query (NOT SQL) in a variable with all the parameters without evaluating it in Django?
Suppose I have a form and from it returns data. After processing and several if-else statements with respect to the data( for example, the initial query might be x = User.objects.filter(active=True) and after that, suppose a value from the form say created_before is present then the query is further changed to x.filter(created_at__lte=created_before) and so on.), the variable x will have a query. I want to be able to see that final query without evaluating it. If I use the .query it only returns the RAW SQL query. If I print the variable the query gets executed. Is there a way to do this? -
Django dynamic forms - problem creating a select widget (dropdown)
I am using Django 2.2. I am creating a dynamic form (unbound to a model). I have managed to create several form inputs dynamically (including inputs accepting more than one choice), but I am having problems creating a select (i.e. dropdown) form input element. When I render my form using {{ form.as_p }} in my template, the select form field is being rendered as checkbox instead. I have tried ALL of the statements below, and the result is the same: the form input field is still rendered as a checkbox. form_field = CharField(label=the_label, widget=forms.Select(choices=CHOICES, required=is_required)) form_field = ChoiceField(label=the_label, choices=CHOICES, widget=Select, required=is_required) form_field = ChoiceField(label=the_label, widget=Select(choices=CHOICES), required=is_required) How do I force django to render this field as a select (drop down) field? -

Override the django translation method
I wish to find a simple way to override the gettext method use by Django. I wish to create my own method and tell Django to use it everywhere (.py, Template …). In my .py it's simple, I can use my new method directly but in the Django engine I do not know how to do it ? My aim is to use a database of translations + Google Cloud Translation. I do not find a way to do it … but Django si perfect, so I suppose there is a way ? :) -

How to fetch image from django FileResponse using javascript
I would like to render an image in html using javascript, and the image is being retrieved from a django view using the fetch api. I think I am close but can't figure out how to display image in browser using javascript. view #1: (url: builds/imgretrieve/int:device/) class imgRetrieve(generics.GenericAPIView): permission_classes = (permissions.IsAuthenticated,) def get(self, request, *args, **kwargs): device = self.kwargs['device'] deviceVals = CustomUser.objects.get(id=device) buildImg = ImageRequest.objects.filter(author = deviceVals).latest("dateAdded") return FileResponse(buildImg.image) When I access this view directly using a browser, it displays an image as expected. However when I want the javascript to display it in a different view, it just displays [object Response] instead of the image. Here is how I am attempting to do this: view #2 (url: builds/chamberCam/int:device/) class chamberCamView(LoginRequiredMixin,TemplateView): template_name = 'chamberCam.html' login_url = 'login' def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) device = self.kwargs['device'] deviceVals = CustomUser.objects.get(id=device) CustomUser.objects.filter(id = device).update(imgRequested = True, imgReceived = False,) context['deviceName'] = deviceVals.UserDefinedEquipName context['deviceID'] = deviceVals.id return context html {% block body %} <p hidden id = "id">{{ deviceID }}</p> <div class="">Chamber cam for {{deviceName}}</div> <div class="imageDiv" id = "image"> </div> {% load static %} <script src="{% static 'camera/chamberCam.js' %}"></script> {% endblock %} chamberCam.js let deviceID = document.getElementById("id").innerHTML; getImg(deviceID) function getImg(deviceID){ fetch('http://127.0.0.1:8000/builds/imgretrieve/' + … -
Deplying Django to Heroku - DisallowedHost Error despite Heroku URL in DJANGO_ALLOWED_HOSTS
I've been at this for hours and need help. Initially I thought it was because I had mistakenly done something small that caused it, so I deleted the app, and created everything - virtual env, heroku app, django projects/apps - fresh. I get the same error. I made a cookiecutter django app and deployed it to heroku. Everything goes smoothly until it's time to actually use the site. When I run heroku open, I get the DisallowedHosts error: DisallowedHost at / Invalid HTTP_HOST header: 'MY-NEW-APP.herokuapp.com'. You may need to add 'MY-NEW-APP.herokuapp.com' to ALLOWED_HOSTS. heroku config shows that DJANGO_ALLOWED_HOSTS=MY-NEW-APP.herokuapp.com. I don't overwrite it in my settings file. I have import django_heroku and django_heroku.settings(locals()) in my settings file. DJANGO_SETTINGS_MODULE is correctly set to that file. What's more, I get a warning about DEBUG=True, when DEBUG=False in my settings file and in the heroku environment. What am I missing? Are hyphens a bad thing? Should I be using herokuapp.com instead of the full URL? -
