Temporarily saving file objects and cleaning up once done (Django)
I'm creating a Django website where users post details of used items they want to sell/barter. When posting an item, the second-last step is to upload (upto 3) photos of the item on sale. The last step is to provide personal details (name, address, mobile). After this, the ad is finalized and goes into a "pending approval" queue. I don't want to save photos to the DB until an advert is finalized. Hence I'm thinking I'll return an InMemoryUploadedFile object and do: request.session["photo"] = InMemoryUploadedFile(thumbnail_string, None, 'temp.jpg', 'image/jpeg', thumbnail_string.len, None) Would this work? I've seen various criticisms that file objects aren't serializable, meaning I could be mistaken here. Next, once ad is final, I'll save the images in my backend and pop photo from the request.session dictionary. Even if saving in request.session works, how would I handle cases where a request.session["photo"] entry was created, but the user never finished the ad? I don't want to have such 'orphan' images lying in my server memory. -
Is it ok to change request.POST._mutable
Django 1.11.2 Do you think this is a good style or not: In CBV: request.POST._mutable = True request.POST['{}_date_day'.format(prefix)] = ceil_day(day=day, month=month, year=year) request.POST._mutable = False The program works well. I'm satisfied. What troubles me is whether this is ok or not. Maybe it is really a bad practice. I mean, is it acceptable that we should change the private property _mutable? -
How can I control Django-admin panel permissions across two apps?
I have two apps "App1" & "App2". Using "App2" views.py I want to display the information about models of "App1" but with only read-only permissions. like just display the info in the same manner Django-admin does. -
how can I securely perform Rest requests without authentication?
This is more a process logic question than a specific language-framework one. I am developing a mobile app and want the user to be able to use it without having to login (i.e. try it and offer a plus to the logged users), but I don´t want other persons to make post requests from let´s say Postman or any other platform than the app without having some sort of key, so what would be the approach here? I am thinking on basic auth with some secret username:password for guests, or some kind of token, but as I am totally new on this I am not sure if it´s the correct approach, I´ve read the authentication and permissions Django Rest Framework tutorial but haven´t found a solution -
Getting 415 code with django.test.Client's patch method
When I send a PATCH request to my Django app running on localhost via the command line like so: http -a <username>:<password> PATCH http://127.0.0.1:8000/post/1/ text="new text" It works as expected and I get a 200 OK code back. When I try to do the same thing in my unit test using the django.test.Client.patch method like this: In [1]: from django.test import Client In [2]: client = Client() In [3]: client.login(username='<username>', password='<password>') Out[3]: True In [4]: client.patch('/post/1/', {'text': 'new text'}) Out[4]: <Response status_code=415, "application/json"> I get a 415 (Unsupported Media) response code. If I try adding the parameter content-type='application/json' to the patch method (I shouldn't have to do this because I'm able to send GET, POST, and DELETE requests using the Client class without providing that parameter) I get a 400 error code. As I said, when I use the class's get, delete, and post methods, the behavior is as expected. Am I using the method properly? Is this a bug? -

get tuple list element by string name in python
I have the following tuple list: It is for choice fields in a django model. ENTITY_TYPE_CHOICES = ( (0,'choice1'), (1,'choice2'), ) I want to get the choices by their string name like: entity_type_index = ENTITY_TYPE_CHOICES['choice1'] I get the error: tuple indices must be integers, not str -
Changing field type in a Django view
I have a project, where people will be able to create variables for a form, and then other users will fill that form. When they create the said form, they can chose the answer to be of 3 different types : From a list of value, an integer, or a string. Basically, I create a formset of all the variables the user created for this form, but if it is a list, I want to change the type of the input from a CharField to a ChoiceField. So this is my view : def insererDonnee(request, modele, contexte=-1): variables = Variable.objects.filter(modele=modele) varIter = variables.iterator() DonneeFormSet = formset_factory(InsertDonneeForm, extra=variables.count()) submitAdress = "insererDonnee" if request.POST: formset = DonneeFormSet(request.POST) else: formset = DonneeFormSet() for formx in formset: formx.variable = varIter.next() formx.nomVar = formx.variable.nom formx.fields['valeur'].label = formx.nomVar # Here I call setList to change the type if formx.variable.type_variable in ["SOLIST", "LIST"]: formx.setList(formx.variable) And my form: class InsertDonneeForm(forms.Form): variable = Variable() nomVar = 'Variable' valeur = forms.CharField(label=nomVar, max_length=100) def setList(self, variable): choices = ListItem.objects.filter(variable=variable, modele=variable.modele) valeur = forms.ModelChoiceField(queryset=choices)# or None) print valeur The last print was just to see if the field was indeed changed, which it is, but if I do the same print in … -
Getting related_descriptors.RelatedManager instead of getting unique model object by id

Docker: How to rely on a local db rather than a db docker container?
Overall: I don't want my django app to rely on a docker container as my db. In other words, when I run an image docker run -p 8000:8000 -d imagename I want this to know to connect to my local db. I have my settings.py configured to connect to a pg db, so everything is fine when I do something like python manage.py runserver Feel free to call out any incorrect use of certain terms or just my overall understanding of docker. So from all the tutorials I've seen they usually make a docker compose file that is reliant on a db-image that will be spun up in a container separate from the web app. Examples of things I've gone through: https://docs.docker.com/compose/django/#connect-the-database, http://ruddra.com/2016/08/14/docker-django-nginx-postgres/, etc. At this point I'm extremely lost, since I don't know if I do this in my Dockerfile, settings.py in my project, or docker-compose.yml (I'm guessing I shouldn't even have this since this is for a multi-container app which I'm trying to avoid). [Aside: Lastly, can one run a django app reliant on celery & rabbitmq in just one container? Like my pg example I only see instances of having them all in separate containers.] As for … -

Django manage.py commands that require input get stuck
Since a while any python manage.py command that requires an input (removing null=True without providing default, recollecting static files...) does not accept said input. when I press enter it simply displays the carriage return char ^M in the console. I have no Idea how to debug this, as ctrl+ c simply gives tracebacks like these: ./manage.py makemigrations You are trying to change the nullable field 'package' on company to non-nullable without a default; we cannot do that (the database needs something to populate existing rows). Please select a fix: 1) Provide a one-off default now (will be set on all existing rows with a null value for this column) 2) Ignore for now, and let me handle existing rows with NULL myself (e.g. because you added a RunPython or RunSQL operation to handle NULL values in a previous data migration) 3) Quit, and let me add a default in models.py Select an option: 1^M^M^M^C^CKeyboardInterrupt The above exception was the direct cause of the following exception: Traceback (most recent call last): File "./manage.py", line 22, in <module> execute_from_command_line(sys.argv) File "/Users/mac/.virtualenvs/mindance/lib/python3.6/site-packages/django/core/management/__init__.py", line 363, in execute_from_command_line utility.execute() File "/Users/mac/.virtualenvs/mindance/lib/python3.6/site-packages/django/core/management/__init__.py", line 355, in execute self.fetch_command(subcommand).run_from_argv(self.argv) File "/Users/mac/.virtualenvs/mindance/lib/python3.6/site-packages/django/core/management/base.py", line 283, in run_from_argv self.execute(*args, **cmd_options) File … -

How do I get an Django ViewSet to return a 403 error on anonymous post
I'm trying to get my app to return a 403 error when an anonymous user attempts to POST to it. Right now it returns a 201 code, but doesn't save the post to the database.

Here is my model: class Association(models.Model): ''' For members declared as groups ''' member=models.ManyToManyField(User,related_name='association_user') name=models.CharField(max_length=50) def __str__(self): return self.name class Meta: ordering=('name',) The many-to-many relationship ended up creating, i think, a table under the hood with the following definitions: association_id user_id I don't know if it is refering to the that field association nor how to add values to that table from my views. my forms.py class NewAssocationForm(forms.ModelForm): ''' this is used to create a new form ''' class Meta: model=Association fields=['name',] labels=['Assocation Name'),] and my views.py: @login_required def make_new(request): ''' Register a new association or corporate ''' if request.method=='POST': form=NewAssocationForm(request.POST or None) if form.is_valid(): new_association=form.save(commit=False) new_association.member=request.user new_association.save() #add a message then redirect return HttpResponseRedirect('/corporates/done/) else: form=NewAssocationForm(request.POST or None) else: form=NewAssocationForm(request.POST or None) return render(request, "association_new.html", locals()) I don't have a field named association in my model at all. I doubt it is constraint erorr cos i can insert records to the table from the shell without any issues. Here is my traceback.

Setting up a Django development server that can be accessed by other devices on my network
I want to set up a Django development server that both my computers and smart phones can access whilst on my network via wifi. I've already set up a development server that my computer can access on http://127.0.0.1:8000/. However, my other devices can't. The Django documentation says: "Note that the default IP address, 127.0.0.1, is not accessible from other machines on your network. To make your development server viewable to other machines on the network, use its own IP address (e.g. 192.168.2.1) or 0.0.0.0 or :: (with IPv6 enabled)." I've found my "public IP address" and tried to use this by: python manage.py runserver xx.xx.xxx.x (where this is my public ip address) but i get a command error that this is not a valid port number or address:port pair. I then tried the same with :8000 after the IP address, but got an error "Error: That IP address can't be assigned to". Then python manage.py runserver 0.0.0.0:8000. The command line reports the development server has started, but when i try "http://0.0.0.0:8000/" on Chrome, i get a "This site can't be reached error". Is it something to do with my windows firewall settings? Please can you someone help me? Thanks! -
Dynamic checkbox checked
Currently, I'm using a simple form to display a list of games. This list is presented with checkboxes. The user just check a game to add it to his favorite games. So basically, when the user is back to the list, I just want to make the user able to check or uncheck a game from the list. But I don't know how to check a game if the user already selected it Any idea ? Thanks ! forms.py : class GamesRegisterForm(forms.Form): favorite_games_choices = [] for game in Games.objects.all().order_by('title'): favorite_games_choices.append((game.guid, game.title), ) favorite_games = forms.MultipleChoiceField( required=True, initial=True, widget=forms.CheckboxSelectMultiple(), choices=favorite_games_choices, ) class LogonForm(forms.Form): email = forms.EmailField( ) password = forms.CharField( widget=forms.PasswordInput, min_length=8, ) models.py class Games(models.Model): guid = models.CharField(max_length=100, unique=True, null=False, verbose_name="GUID") title = models.CharField(max_length=100, null=False, verbose_name="Titre") logo = models.CharField(max_length=100, null=True, blank=True, verbose_name="Logo") date = models.DateTimeField(auto_now_add=True, auto_now=False, verbose_name="Date de création") update = models.DateTimeField(auto_now=True, verbose_name="Dernière modification") def __str__(self): return self.title class FavoriteGames(models.Model): game = models.ForeignKey('Games') user = models.ForeignKey(settings.AUTH_USER_MODEL) -
