GeoDjango GDALException - OGR failure
After installing GeoDjango, I wanted to create a 'Location' object in the admin panel which uses an address and a point on a map. After submitting the form, I get an error like so...

Python Spyne XML GET (not POST)
I am creating a simple Web Service using Spyne, the client (which I don't control) send a GET to verify that SSL is up and working. The Spyne service I created responds with an error, saying only POSTS are supported. Any ideas on how I can make it respond to a simple get on the same path? Example of the code (using Django, but that shouldn't make a difference): views.py: class QWCService(ServiceBase): @rpc(Unicode, Unicode, _returns=Array(Unicode)) def authenticate(ctx, strUserName, strPassword): print "authenticate" return ["auth","success"] app = Application([QWCService], 'my.namespace.com', in_protocol=Soap11(validator='lxml'), out_protocol=Soap11(), ) app_service = csrf_exempt(DjangoApplication(app)) urls.py: urlpatterns = [ url(r'^admin/', admin.site.urls), url('^qwc', app.views.app_service, name="root"), ] The only way I can figure out how to get around this is to flip the URL to a blank page, then flip it back after the check for SSL is done. Error from Spyne: Soap11env:Client.RequestNotAllowed You must issue a POST request with the Content-Type header properly set. -

Django : Digital Ocean Spaces/AWS S3, how to create image using django_storages
I am trying to user django_storages package for storing images on AWS S3 or Digital Ocean spaces. When I use normal image upload using a form, the image is successfully getting uploaded to the server. But When I try to create an image manually and then write it to S3 or Digital Ocean Space buckets, the image is not getting created properly. Following is the code which I have run on Shell and tried alot: from PIL import Image, ImageDraw, ImageFont img = Image.new('RGB', (500,500), (255,255,255)) d = ImageDraw.Draw(img) d.text((10,10), "Hello", font=ImageFont.truetype("tahomabd"), fill='BLACK') d.text((10,60), "World", font=ImageFont.truetype("tahomabd"), fill='BLACK') from django.core.files.storage import default_storage as storage JPEG_PATH = "pathtofile.jpeg" storage.exists(JPEG_PATH) storage.delete(JPEG_PATH) JPEG_STORAGE = storage.open(JPEG_PATH, "w") JPEG_STORAGE.write(img) JPEG_STORAGE.close() The above code creates a .JPEG file on the storage location but it is some default file which does not make any sense. Please suggest what is issue with the code. -

using Django crispy forms, how do you shrink the text box for a TextField?
The text boxes that crispy forms lay out for TextField columns are too tall for my app, they are taking up too much screen space. The user can make them taller if desired by dragging the bottom frame line, but the minimum size is too tall. I would like the default height to be 4 rows or so. I tried some ideas I got off related posts, but nothing worked -- the text boxes were still the same height and too tall. Guidance would be appreciated. -

Django model.delete() method returning successful delete but not actually deleting
I am using Django 2.0. I make an AJAX call to a function in Django that should allow a user to vote on a post or remove their vote from a post. When I call the .delete() method on a model, the model returns a result as if it was being deleted, but the record is not removed from the database. Here is the Django function: if request.method != 'POST': raise Http404 post_id = request.POST.get('postId') vote_type = request.POST.get('voteType') # If vote_type isn't valid, 404 if (not any(vote_type in allowed_vote_type for allowed_vote_type in Vote.ALLOWED_VOTE_TYPES) or not 'null'): raise Http404 post_queryset = Post.objects.filter(pk=post_id) post = get_object_or_404(post_queryset) try: vote = Vote.objects.get( post=post, user=request.user ) print('Vote object found') # User has already voted on this post. # Update user's vote. if vote_type == 'upvote': print('vote_type is upvote') if vote.vote_type == 'upvote': print('Deleting vote.') # User just upvoted twice.

if I use ModelForms then dont know how to modify fields
The table has 2 fields. trackword and created_by If I include the field "created_by" in the forms.py yes, I get a select list, I can select the creator and it is saved alright, but, obviously it is superfluous that one has to manually make use of a select list to say who is adding the trackword because on the one side, it is the person logged in, and secondly, it creates me the problem that other users will see the other existing users in the select list, and that should not be viewable by others. So, if my Form code looks like this: @login_required def add_trackword(request): form = masterform(request.POST or None) if request.method == 'POST': if form.is_valid(): form.save() messages.add_message(request, messages.SUCCESS, "The post has been saved!") return HttpResponseRedirect("/trackwords/list/") return render(request, 'masterform.html', {'form': form}) FORM <div class="row" > <div class="panel panel-default col-md-4"> <div class="panel-body"> <form action="" method="post">{% csrf_token %} {{ form.as_p }} <input type="submit" class="btn btn-block btn-success" value="Submit"> </form> </div> </div> </div> as you see, the form is automatically created by the django model form engine and while I dont HAVE TO write any field, neither CAN I If I need to. or I dont know how how to.

Django, users in group sorted

Translating 'Django-Oscar'
I want to learn how to build an opensource e-commerce site. For this purpose I'm using 'Django' framework with 'Oscar' extension. I read the whole tutorial here: https://django-oscar.readthedocs.io/en/releases-1.5/index.html, where there is a Translation tutorial. I followed it (must say that it has missing steps). This part says that, in order to translate a page you must create two folders and a symbolic link: mkdir locale i18n ln -s $PATH_TO_OSCAR i18n/oscar Then, for each language you want to translate: ./manage.py makemessages --symlinks --locale=<language code> That's correct but, besides that, you must compile .po files in order to get the final traduction in locale folder (.mo files). After that you must include the traductions into settings.py of project (or app). This is done with the following code: In terminal (from root directory of project): $ django-admin.py compilemessages In settings.py add: LANGUAGES = [ ('de', _('German')), ('en', _('English')), ('es', _('Spanish')), ] (Note: This is my case, where I want to translate the store into German, Spanish and English) After doing that, I run my server and only these three languages appear in the select language box, but when I push the button in order to translate the page, It returns the default language … -

AJAX Post request not sending values to Django View
