Redirecting public url fails on django - SignatureDoesNotMatch
Im trying to download a file from s3 to a client throught django. In order to do this Ive generate a public url from the s3 object required and the Im trying to redirect the user to that url, so the file is downloaded to his/her computer. The code is the following def generate_public_url(self, bucket, file) url = '' filename = file client = boto3.client( 's3', ) url = client.generate_presigned_url( ClientMethod ='get_object', ExpiresIn = 7200, Params = { 'Bucket': bucket, 'Key': file, } ) return url The code that redirects the url: from .django.http import HttpResponseRedirect . . . http_response_redirect = HttpResponseRedirect(url) return http_response_redirect And the response from aws is 403 with the following error: Code: SignatureDoesNotMatch Message: The request signature we calculated does not match the signature you provided. Check your key and signing method. After doing some research for a few days and trying a lot of things, Im sure this is a problem with django, and after reading some post in github people says that if the headers include something different compare to the ones used to generate the public url it can generate this error. So something in the django way of making the request must … -
Django - How to filter by annotated value
Consider the following model. I'd like to filter objects based on the latest timestamp, which might be either created_at or updated_at. For some reason, the filter function does not recognise the annotated field and I'm having hard time finding the appropriate code examples to do this simple thing. The error message is "Cannot resolve keyword 'timestamp' into field.". How would you retrieve the Example objects within 7 days, based on newer date. from datetime import timedelta from django.db import models from django.db.models.functions import Greatest from django.utils import timezone class Example(models.Model): created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(null=True) @property def recently_updated(self): return Event.objects .annotate(timestamp=Greatest('created_at', 'updated_at')) .filter(timestamp__gte=timezone.now() - timedelta(days=7)) .order_by('-timestamp') Django 1.11 -

I am a newbie to django. I have my django app running in docker, I need to create a superuser without using the createsuperuser command I tried using this code initadmin.py (shown below) but I am not able to run it in a bash file using "python manage.py initadmin".

Django filtering: from a list of IDs
I'm using Django Rest Framework. The model class is class MyModel(models.Model): id = models.CharField(max_length=200) name = models.CharField(max_length=200) genre = models.CharField(max_length=200) And what I have set up so far is that, when the user does a POST request, the backend will take the request data and run a python script (which takes some parameters from the request data) which will in turn return a list of IDs corresponding to the "id" in MyModel. But the problem is, let's say I want to return only the ids that point to the model instances with genre "forensic", how do I do that? I don't really have a clue how to do that, apart from doing a query on each id returned by the python script and filtering out the ones I want based on the genre returned from the query? -
How to enable HTTP access for Django APIs on HTTPS server

Use django multiple settings config, is that OK or fine? I mean recommended way
I want django settings like spring boot *.yml settings way to develop, default settings could set, and active settings could overwrite default settings. I trid many ways, finally find this way blow, I want get some recommendations or advices. refer to Django multiple settings I create project.settings module and add multiple settings file, and change the manage.py like: import os import sys from mysite.settings import settings if __name__ == '__main__': os.environ.setdefault('DJANGO_SETTINGS_MODULE', settings.ACTIVE_SETTINGS) In default settings.py file add ACTIVE_SETTINGS for manage.py to import. default setting file mysite/settings/settings.py like: import datetime import os ACTIVE_SETTINGS = 'mysite.settings.dev_settings' more default settings..... In develop dev_settings.py file set default settings refer to #custom-default-settings in mysite/settings/dev_settings.py like: from django.conf import settings from mysite.settings import settings as default # use this could set default settings to active setting settings.configure(default, DEBUG=True) more dev settings..... Setting django in this way could realize only change one setting ACTIVE_SETTINGS to develop and default settings could also set if ACTIVE_SETTINGS file not set, I've read many blogs, no other way could better than this. -
TextField onchange feature with Django CMS Wizard, Form and App Config
I am developing a website using django CMS. In their built-in app config for Pages (for example), they have a field wherein we can input a slug for the page we create. By default, while you type the page title, the slug textfield also types in a value automatically in a slug format, like below: I want to learn how to do this in my custom app configs as well as on my CMS wizards. Reason being, we will have non-technical staff who will later be given permission to add events and news. Adding events and news requires providing a slug which will be used later for URL routing. Since they are non-technical personnel, it is not ideal for them to provide the slug manually i.e. they might forget to add a hyphen or misspell some words. Thus, it would be safer to just automatically fill the slug field with default value as you type the page title. If anyone can share a piece of code or share the concept on how to do this as simple and straightforward as possible it would greatly help. Cheers! -
MySQL row-column-value format to python dictionary

How to pass variable as ARG or KWARG in my get_success_url
I have been working all afternoon to try and pass a variable to a get_success_url to show the correct record after I process an UpdateView. I am using class based views, and I am trying to update a record and then show the corresponding update record in a different view. However, when I am passing the pk, it works but it's not the right one. Essentially, here is the code in question... def get_success_url(self): return reverse_lazy('Book:create_new_author_detail', kwargs={ 'pk' : self.object.pk }) The above would work fine and does in many scenarios. However, in this case, I am trying to pass a specific pk that does not align with this particular updateview. I have tried something like.... def get_success_url(self): return reverse_lazy('Book:create_new_author_detail', kwargs={ 'pk' : self.object.new_author.pk }) Perhaps something like.... def get_success_url(self): return reverse_lazy('Book:create_new_author_detail', kwargs={ 'pk' : self.object.pk, 'new_author' : self.new_author.id }) Would work? I can get the pk using this code, just not the right one. I want to reference new_author.id so that the reverse_lazy picks the right pk. Thanks in advance for any thoughts. -
How to fix 'NoReverseMatch at /' error on Django app?
I'm new to Django and I'm trying to just build a basic application to work off in the future. I keep getting an error saying "NoReverseMatch at/ Reverse for 'about' not found. 'about' is not a valid view function or pattern name." I've searched for other people with the same issue and it seems their issues used an older version of Django and they used different functions from what I'm using. I'm using a book called Hello Web App by Tracy Osborn, which simplifies everything, and all the code I've found dealing with a similar problem seems far more complicated than what I've done so far. I've tried changing my views.py file to request the base.html file instead of the index.html file which didn't work. I've double checked my syntax on all files, including the html file. And, I've made sure the urls.py file matched up exactly. I still keep getting the same error. here is my urls.py file from django.contrib import admin from django.urls import path from django.views.generic import TemplateView from condata import views urlpatterns = [ path('', views.index, name='home'), path('about/', TemplateView.as_view(template_name='about.html'), name='about'), path('contact/', TemplateView.as_view(template_name='contact.html'), name='contact'), path('admin/', admin.site.urls), ] views.py from django.shortcuts import render # Create your views here. … -

I fix it but when I run my apache server and tried to make a request in the logs I found this: [Mon Jun 17 17:31:02.934215 2019] [wsgi:error] [pid 29830] [remote 200.116.66.129:52114] from .migration import Migration, swappable_dependency # NOQA<br/> [Mon Jun 17 17:31:02.934240 2019] [wsgi:error] [pid 29830] [remote 200.116.66.129:52114] ModuleNotFoundError: No module named 'django.db.migrations.migration' I looked in this other question: Updating Django - error: 'No module named migration' and tried every posibility unsuccessfully. What else should I do to fix this? -
How to create checkboxes with the values of model instances created by users
I want to create forms with checkboxes in them which values of these checkboxes is a model instance created by users. Here is my SessionModel: class SessionModel(models.Model): starting_time = models.TimeField() . . Imagine that I have several instances of this model with various starting_times. and I have another model which is: class TimeModel(models.Model): time = models.TimeField() now i want to select the required instances of SessionModel and update them. But the problem is that I want to have a form with checkboxes with the values of TimeModel.time to grab the instances in SessionModel with the starting_time same as selected TimeModel.time but I don't know how to create these checkboxes should I use dynamic forms or is there any other way I can do this? -
How do I add information from javascript variables to Django ModelForm input?
I am building a web application using Django. The page shows a large leaflet map, in which users can select one out of several layers. I want users to be able to select a layer, click on the map and add a note to that location and that layer. I've created a model form, which holds the note itself. This works fine, and saves to my database. However, I need to also include the currently selected layer and mouse-click-location, which is readily available as a JS variable. How do I pass this on in Django? My views.py holds the following: if request.method == 'POST': form = MapNoteForm(request.POST) if form.is_valid(): form.save() else: form = MapNoteForm() And forms.py: class MapNoteForm(forms.ModelForm): note = forms.CharField() class Meta: model = MapNote fields = ('note',) Finally, the relevant section of the template: map.on('click', function (e) { var MapNote = L.popup(); var content = '<form method="post"> {% csrf_token %} {{form}} <br> <button type="submit"> Save</button>' MapNote.setContent(content); MapNote.setLatLng(e.latlng); //calculated based on the e.layertype MapNote.openOn(map); }) I'm kind of looking to reverse the workings of the Django-view, trying to pass something from the template to Django, instead of vice versa. What would be the best approach here?
