Within a view, how do I return the MEDIA_URL for Imagefield queryset?
Assume I have the following model: class ProductImage(models.Model): image = models.ImageField('Product image', null=True,blank=True) view = models.CharField(max_length=2, choices=VIEW_TYPES, default='FR', null=True,blank=True) description = models.CharField(max_length=125, blank=True, null=True) def __str__(self): return self.view + "-" + self.image.url I have the following queryset: allProductImages = ProductImage.objects.all() How do I extract the MEDIA_URL + path + filename for all objects (e.g. /media/image.jpg) here's what I have already tried (follows on from previous queryset statement): urlValues = allImages.values('image') <QuerySet [{'image': 'greenSwatch.jpg'}, {'image': 'blueSwatch.jpg'}, {'image': '3037-outer-black.jpg'}, {'image': '3037-outer-black.png'}] I'm trying to get the following: <QuerySet [{'image': '/media/path/greenSwatch.jpg'}, {'image': '/media/path/blueSwatch.jpg'}, {'image': '/media/path/3037-outer-black.jpg'}, {'image': '/media/path/3037-outer-black.png'}, {'image': '/media/path/3037-inner-blue.png'}, {'image': '/media/path/3037-outer-green.png'}, {'image': '/media/path/3037-outer-blue.png'}]> Also, I know there's no upload_to parameter specified, but this is optional according to the docs for Django 1.10 I'm running Django 1.10 + Python 3.5 -

Register admin models using django-polymorphic
I am converting existing models/admin over to django-polymorphic. I think I have the models and migrations done successfully (at least, it's working in the shell) but I can't get the admin to work.

Django Rest Framework invalid username/password
Trying to do a simple 'GET' wih admin credentials returns "detail": "Invalid username/password." I have a custom user model where I deleted the username, instead I use facebook_id : USERNAME_FIELD = 'facebook_id' I tried changing the DEFAULT_PERMISSION_CLASSES: ('rest_framework.permissions.IsAuthenticated',), -- doesn't work! ('rest_framework.permissions.IsAdminUser',), -- doesn't work! The only one that works is: ('rest_framework.permissions.AllowAny',), But I do not want that, since I'm building an API for a Mobile App I also declared a CustomUserAdmin model and CustomUserCreationForm , apparently this was not the problem Help me understand what needs to be done to fix this annoying problem, I'm guessing it might have something to do with Permissions/Authentication or the fact that I CustomUserModel.. Also, let me know if there is a better way for a mobile app client to authenticate to the api -
django - validate model with ForeignKey
I have two models class MainThing(models.Model): ... total_amount = models.IntegerField() class SubThing(models.Model): main_thing = models.ForeignKey(MainThing, related_name='subthings') sub_amount = models.IntegerField() For various reasons, I need the total_amount equal to the sum of sub_amount for all SubThings linked to the same MainThing (yes, I need the redundancy). I am trying to write a validator for this, and as I am using django-rest-framework and the admin site and possibly standard views/forms, I would like to write the validator once only, which I understand means ModelForm.clean() doesn't do the trick. I tried putting this in MainThing.clean() but then I don't have access to the SubThings (self.subthings.count() gives me 0 when creating new objects) so I don't know how to calculate the sum. My best option at this point seems to be SubThing.clean() but then I need to test if we are adding or changing an object, which becomes ugly, and error messages are not produced at the right level (they should come at main level, not sub). What is the proper way to ensure consistency of my data in this scenario? I want to throw a ValidationError if my tests fails, and ideally not leave the database in a half saved state. I will … -

Virtualenv and Pip hanging forever
I am running a django project with a virtualenv that was working completely fine up until this afternoon. I went to run source my-env/bin/activate and it seemed to activate (it gave me the usual command prompt), but when I tried python manage.py runserver it said it could not locate django. I ran a python script and tried to import django and sure enough it said there was no module named django. So I removed this virtualenv and created a new one and did a pip install -r requirements.txt. It was then I noticed that pip was hanging forever and upon type ^C it would give a long traceback which I will provide below. Once this happened I tried once again to delete the virtualenv and start over only now when I typed virtualenv new-env it would hang on "Installing setuptools, pip, wheel..." and also gave a long traceback upon entering ^C. I have looked all over the online forums and tried everything to fix this and nothing seems to be working. I am incredibly pissed because now I am unable to work on my app. If anyone has any ideas on how to fix this I would really appreciate it. … -
Can not write proper filtering queryset
There is such content type model: class CTModel(models.Model): content_type = models.ForeignKey(ContentType, on_delete=models.CASCADE) object_id = models.PositiveIntegerField() content_object = GenericForeignKey('content_type', 'object_id') sport = models.ForeignKey(SportTypes) QuerySets: user_type = ContentType.objects.get_for_model(UserProfile) current_sport = Sports.objects.get(name='Football') rest_sports = Sports.objects.exclude(name__in=RANDOM LIST OF GAMES) # Here I want to get all users who play 'Football' users_play_football = CTModel.objects.filter(content_type=user_type, sport=current_sport) # Here I want to get all users, who play Football, but does not play any other games from 'rest_sports' users = users_play_football.exclude(sport=rest_sports) As a result, if a user plays 'Football' and any other game from rest_sports, I expect to get users empty, but it is not! I mean I want to get users empty in case if my user plays just Football. Where is my mistake? -
How to access variable from html/python to JavaScript?
We have a project setup implemented in Django and we're trying to create a search function. Currently, we pass our database of users from view.py to our .html file (view.py code below) def search(request): template_name = "search/search_it.html" users = models.Profile.objects.all() context = {'users': users} return render(request, template_name, context) Inside of our html code is where we are having issues.

Our html file uses a onclick button into javascript. We have decided to try to tackle this various ways including: Use the javascript value outside of the - Did not work for obvious scope reasons Try to load the names into strings and then grab each name inside of the javascript - Messy and not proficient and (what we would like to do) Load each user into a javascript array that can be used … -
Django app and HTTPS
I am kinda new to this and I looked at other threads but sadly I found nothing similar. I am trying to access my Django app through https by using nginx+ uwsgi. The problem that I am having is that I cannot install uwsgi on my laptop as I am using windows. I am also planning on dockerizing the whole thing, so can you as well give me some tips for doing that. I have already got my SSL key + cert using OpenSSL. -
Cannot run Django development server
I'm new to Django and have gone through the recommended installation (set up for GeoDjango) and am now going through the general django tutorial to get an idea of how it works. IN the tutorial https://docs.djangoproject.com/en/1.10/intro/tutorial01/, it tells you to try and run the django development server with python manage.py runserver but when I do I get an error System check identified no issues (0 silenced).

Deploying Django With AWS
So I am trying to deploy my django app(which mostly has REST Apis) but when I use Amazon CLI, I end up having Fedora instance, while I want to use Ubuntu instance. So I tried to do this, I made an ubuntu instance, made a repository of my code, installed git on ubuntu and cloned the code from git to ubuntu. Next thing, I installed all the requirements.txt dependencies and everything is in virtualenv and working fine. But here's the catch, python manage.py runserver runs it on localhost(not really surprising). So the question is, how to serve those apis(not on localhost)? -

Gmail authentication error when sending email via django celery

How to filter objects in mongoengine using 'LIKE' statement?
I have following json structure in my mongodb. { "country": "spain", "language": "spanish", "words": [ { "word": "hello1", .... }, { "word": "hello2", .... }, { "word": "test", .... }, ] } I am trying to get all the dictionaries inside 'words' list which have particular substring matched. For example, If I have a substring 'hel', then how should I query my document using mongoengine that gives two dictionary with word : 'hello1' and 'hello2' The following query works only for matched word not with the substring. data = Data.objects.filter(words__match={"word":"hel"}) // data is empty in this case([]) -
django: how to know if a model is created with a m2m field not None
So basically I am trying to override the save method of a model to tell if a certain non-required field, which is a m2m field, is specified. If so, then update one of its own Boolean field to True. Currently I have something like this: def save(self, *args, **kwargs): super(Model, self).save(*args, **kwargs) if Model.objects.filter(id = self.id, m2mField = None).exists(): Model.objects.filter(id = self.id).update(BooleanField = True) And this is not working for me now. I don't really care what is in the m2m field, just trying to know if that field is specified by user when creating this instance. TIA -
django url parameters as form default value
I have a search form class PostSearchForm(forms.Form): keyword = forms.CharField(label=_('Search the Courses')) def __init__(self,*args,**kwargs): self.request = kwargs.pop('request', None) super(PostSearchForm,self).__init__(*args,**kwargs) raise Exception(self.request) # This returns none categories = Category.objects.filter(status=True) self.fields['categories'] = forms.ModelChoiceField(queryset=categories, widget=forms.SelectMultiple(attrs={'class': 'some-class'})) Whenever search is made I have a build a form with default value as what they have searched, so what I tried is get the url parameters in form init and set the value but it was returning None due to some mistake. Can any one tell me where I am wrong
