How to auto detect user in django
How To Detect User In Django! i see the most of people use foreign key but i don't want foreign key i want to detect user without foreign key i want to detect which user fill this form for example test or something Here is my views.py def buy_form(request): if request.method == 'POST': usr_buy = user_buy_form(request.POST) if usr_buy.is_valid(): usr_buys = usr_buy.save(commit=False) usr_buys.save() else: return print(usr_buy.errors) else: usr_buy = user_buy_form() context = {'usr_buy':usr_buy} return render(request,'user_buy.html',context) Here is my models.py class user_buy(models.Model): users = models.ForeignKey(user_register_model,on_delete=models.CASCADE) title = models.CharField(max_length=200) payment_method = models.CharField(max_length=500) price = models.IntegerField() Trade_limits = models.IntegerField() Location = models.CharField(max_length=1000) def __str__(self): return self.users.user.username Here is my urls.py urlpatterns = [ path('', views.Buy_List_View.as_view(),name='index'), path('accounts/signup/', views.user_reg,name='register'), path('profile/<username>', views.user_profile, name='user_profile'), path('sell_btc/',views.buy_form,name='buy_form') ] Here is my user_buy.html {% extends 'base.html' %} {% block body_block %} <form class="form-control" method="POST"> {{usr_buy.as_p}} </form> {% endblock %} Here is my forms.py class user_buy_form(forms.ModelForm): class Meta(): model = user_buy fields = '__all__' -
How do I see all sql commands to fully reproduce current state of Django app models (Django 2.2)?
I've read that command python manage.py sqlmigrate <app_name> did that for earlier version of Django (<2.0), but now it requires a migrations's name. Also, there was an option to run python manage.py sql <app_name> in previous versions of Django, but now it doesn't work as well. P.S. I need that list of sql statements to debug test db setup process. -
How do I customise the display text of a related object in a column in Django Tables2?
I'm using Django Tables 2 to display some information from a list of objects, including a column with a related object. I'm trying to change the text displayed in the column that shows the related object. My objects are: Job class Job(StatusModel): ''' Model for jobs ''' STATUS = statuses.JOB_STATUS start_time = models.DateTimeField(_('time'), default=timezone.now) pickup_address = models.TextField() ... destination_address = models.TextField() ... drivers = models.ManyToManyField( 'Drivers.Driver', blank=True, ) ... class Meta: verbose_name = _('job') verbose_name_plural = _('jobs') ordering = ('start_time',) def __str__(self): return self.start_time.strftime('%d/%m/%y %H:%M') + ' from ' + self.pickup_address def get_absolute_url(self): return reverse('job_view', args=[str(self.id)]) ... Driver class Driver(StatusModel): ... current_job = models.ForeignKey( Job, on_delete=models.CASCADE, blank=True, null=True, verbose_name=_('Current Job'), related_name='current_job' ) ... def __str__(self): return self.user.get_full_name() ... My table: class DriverStatusListTable(tables.Table): user = tables.Column(linkify=True, verbose_name=_('Driver')) ... current_job = tables.Column(linkify=True) class Meta: model = Driver ... I want the "current_job" column to show text different to the returned __str__ representation of the Job object - namely: Job.start_time.strftime('%H:%M') + ' to ' + Job.destination_address, but I can't work out how to do this, without changing the __str__ method on the Job object. Any ideas? -
How to get uploaded file location in Django
I define a custom upload_to path for a FileField entry. In models.py I have the following class: class MyModel(models.Model): def user_directory_path(self, filename): folder = 'user_{0}/{1}/{2}'.format(self.publisher.id, datetime.today().strftime("%Y/%m"), filename) return folder file = models.FileField(upload_to=user_directory_path, blank=True, null=True, default=False) in settings.py: MEDIA_ROOT = os.path.join(os.path.dirname(BASE_DIR), 'project/app/uploads/') MEDIA_URL = '/media/' FILE_UPLOAD_PERMISSIONS = 0o644 The upload works fine. What I want is the permalink to this file. When I use {{ mymodel.file.url }} I get just 127.0.0.1:8000/media/filename/ which rise a 404. I would like to have 127.0.0.1:8000/media/user_id/year/month/filename/ -

Recommendations for AWS CodeStar/Pipeline and Python (Django/Flask)
I am quite new to AWS. I did a course called 'AWS Cloud Practitioner Essentials' and then I have recently been doing a certified developer course which I got from Udemy. For a while, I have been interested in python, Django and Flask. It was a little bit interesting setting up an EC2 instance, but what really caught my attention was i) setting up autoscaling groups/load balancers. ii) Elastic Beanstalk iii) CodePipeline and iv) CodeStar. As part of the course, a CodePipeline was setup using Elastic Beanstalk with node.js which created a pre-production environment, manual sign-off and then production release. Within CodeStar it is pretty easy to setup a Django Project, however I am not very confident about a number of things and was looking for a bit of advice. In particular when a Django Project is setup in CodeStar, instead of creating an Elastic Beanstalk item directly in the CodePipeline, it creates two CloudFormation objects called GenerateChange... and ExecuteChangeSet. I must admit that I am not confident with CloudFormation. When I look at the Elastic Beanstalk that is generated by the Django Project, it creates a system with one EC2 instance. What I really wanted to try out was … -

Is this possible to restrict backward relationship lookup in the core model?
Is this possible to restrict (filter) objects on the level of the core model so that none of the related models is able to see the unfiltered results? Let the example be provided: class UserManager(models.Manager): def get_queryset(self): return super().get_queryset().exclude(deleted__isnull=False) def User(models.Model): objects = UserManager() ... def Report(models.Model): users = models.ForeignKey(User, ....) ... I expected this to be working the following way: Report.users will not show record where deleted is not null. But actually, they are shown. -
Django: How to check object category when using Model Inheritance?

Google App Engine Blobstore API on Django
I have an app built in Django and currently deployed on Google App Engine. Everything works fine except for when I want to upload files larger than 32MB. I get an error which says, 413. That’s an error. I have been doing some research and I've come to realize that I have to use Google App Engine's Blobstore API. I have no idea on how to implement that on my Django App. Currently my code looks something like this: Model: class FileUploads(models.Model): title = models.CharField(max_length=200) file_upload = models.FileField(upload_to="uploaded_files/", blank=True, null=True) Form: class UploadFileForm(forms.ModelForm): class Meta: model = FileUploads fields = ["title", "file_upload"] View: def upload_file(request): if request.method == "POST": form = UploadFileForm(request.POST, request.FILES) if form.is_valid(): form.save() form = UploadFileForm() return render(request, "my_app/templates/template.html", {"form": form}) Everything works fine. I would just like to know how to implement Google App Engine's Blobstore API on my current code structure to enable large file uploads. -

Django relation does not exist when running test
I'm using Django 2.2.3 and Postgres. I'm trying to add tests into the project and constantly running into an error django.db.utils.ProgrammingError: relation "auth_group" does not exist at test db creation step, when doing either python ./manage.py test or python ./manage.py test app_name. First of all, my suggestion is that I've messed my db schema a little - some time ago development team was asked to import several tables from another db and I've done it via direct importing using pgsql. Than I created models using python manage.py inspectdb and placed them into a separate app. That command created an initial migration, which looks like that: class Migration(migrations.Migration): initial = True dependencies = [] operations = [ migrations.CreateModel( name='SomeModelName', fields=[ ( 'id', models.AutoField(auto_created=True, primary_key=True, serialize=False, verbose_name='ID'), ), ('some_other_field)', models.CharField(max_length=254, unique=True)), ], options={'db_table': 'some_existing_table_name', 'managed': False,}, ), Everything works fine, since than I've created and applied several migrations without any issues. But now I've got stuck with that tests issue. After a brief investigation I found, that inspectdb also created models for some auth tables, and they are present in models.py of that apps with old tables. So, the following lines are present into initial migration of the discussed app: migrations.CreateModel( name='AuthGroup', … -

Authenticate using Google OAuth2 and Postman
Like a week or two ago I used to authenticate in Postman using Google OAuth2 with no problem. But I believe that Google has changed something, because right now it doesn't take me straight to the result of authentication (which is a redirection to my django backend) with access and refresh tokens in response. But right now it looks like some kind of DDoS prevention redirection and in Postman I got an HTML with the script below, that is not being run (most likely Postman is not running it - thus not forwarding). <script type="text/javascript" nonce="H3VTxxxx1x1Ixxxx/Dr/ng"> xsrfstatemanager.chooseKeyAndRedirect( 'https:\/\/accounts.google.com\/signin\/oauth?client_id\x3d2305xxxx9382-bs4v9fkxxxxnt53cf4skirxxxxkmkj4l.apps.googleusercontent.com\x26as\x3dF-fPfkixxxxyJIIdgxxxxw\x26destination\x3dhttp:\/\/127.0.0.1:8000\x26approval_state\x3d!ChQ4dExxxxUzbndIRxxxxkJZU2UzOBIfWXd1LxxxxDVmT3NkOERFdWhZOThQxxxxdWFSQTVoWQ%E2%88%99AJDr988AAAxxxx0ayvP61bbERtYdABfULE34-qRLGgUd\x26oauthgdpr\x3d1\x26xsrfsig\x3dChkAeAxxxxp2XLUCh0OhQv7fnFihxzJthXPzEg5hcHByb3xxxxzdGF0ZRILZGVzdGluYXRpb2xxxxNvYWN1Eg9vYXV0aHJpcxxxx2NvcGU', 'wHNxxxxQ2EVRv5apbGxxxxLjbgegn_BxxxxoHJxA-2g', 'OCAK',true,true, 'https:\/\/accounts.google.com\/o\/nocookie'); </script> It works fine in browser, as JS is being run and is actually forwarding it.
