How to order fields to create a table from BaseTable in models in django
I've a model that extends from a BaseTable, eg: class BaseTable(models.Model): created_at = models.DateTimeField(auto_now_add=True, editable=False) modified_at = models.DateTimeField(auto_now=True, editable=False) created_by = models.ForeignKey(User, on_delete=models.PROTECT, related_name='%(class)s_createdby', editable=False) modified_by = models.ForeignKey(User, on_delete=models.PROTECT ,related_name='%(class)s_modifiedby', editable=False) class Meta: abstract = True In my model call the BaseTable class Produtos(BaseTable): nome_produto = models.CharField(max_length=100, verbose_name='Nome do Produto') und_produto = models.IntegerField(choices=AUX_PRODUTOS_CHOICES, verbose_name='Und') ativo = models.BooleanField(default=True, verbose_name='Ativo') When I run migrate the table Produtos is created, but the order fields are: created_at, modified_at, nome_produto, und_produto ,ativo, created_by_id, modified_by_id my question: How I order or reorder fields to: nome_produto, und_produto ,ativo, created_by_id, modified_by_id, created_at, modified_at -
TypeError and AssertionError after upgrade to Django 2
I'm tasked with upgrading a Django REST framework project from Django 1.8 to Django 2.x. I already ported the whole code from python 2.7 to python 3.7 and from Django 1.8 to 2.0.13. I'm using virtual envs. I got it running on python 3.7 and Django 2.0.13, and RESTframework 3.11, although I ran into problems while trying to create new objects.

Django - ajax button not updating
I am working on a django project and I have implemented an ajax function that looks like this: $(document).ready(function(){ function updateBtnText(btn, newCount, verb){ btn.text(newCount + " " + verb) } $('#player_likebtn').click(function(e){ e.preventDefault(); var this_ = $(this); var post_like_url = this_.attr('data-url'); var post_likes_count = parseInt(this_.attr('data-likes')) | 0; var addlike = post_likes_count + 1 var remLike = post_likes_count - 1 $.ajax({ url: post_like_url, method: 'GET', post_like_data: {}, success: function(post_like_data){ if (post_like_data.liked){ updateBtnText(this_,addLike,"Unlike") } else { updateBtnText(this_,remLike,"Like") } }, error: function(error){ console.log(error); console.log("error"); } }) }); }); views.py class PostLikeApiToggle(RedirectView): authentication_classes = (authentication.SessionAuthentication,) permission_classes = (permissions.IsAuthenticated,) def get(self, request, slug=None, format=None): obj = get_object_or_404(Post, slug=slug) user = self.request.user updated = False liked = False if user in obj.post_likes.all(): liked = False obj.post_likes.remove(user) else: liked = True obj.post_likes.add(user) messages.add_message(self.request, messages.INFO, '1') updated = True post_like_data = { "updated":updated, "liked":liked } return Response(post_like_data) When I click the player_likebtn the button does not change. When I reload the page, the button changes and shows the correct value. Why is the updateBtnText function called only after I reload the page? Thank you -
Use latest version of python as default
On my Debian server if I run python -V it says it's using Python 2.7.13 even though I have python 3 installed. Why isn't it using python 3 as default by now? I'm trying to deploy a Django app and it's expecting python 3. -
Django 3 Protecting access to media files
I have a simple file upload system to upload and store multiple files model: from django.db import models class Localhost (models.Model): name = models.CharField(max_length=255) date = models.DateTimeField() def __str__(self): return self.name class LocalhostFile(models.Model): file = models.FileField(upload_to="files/%Y_%m_%d") localhost = models.ForeignKey(Localhost, on_delete=models.CASCADE) admin (that I am using to upload files) from django.contrib import admin from .models import Localhost, LocalhostFile class LocalhostFileInline(admin.TabularInline): model = LocalhostFile class LocalhostAdmin(admin.ModelAdmin): inlines = [ LocalhostFileInline, ] admin.site.register(Localhost, LocalhostAdmin) and the urls.py from django.urls import path from . import views from django.conf import settings from django.conf.urls.static import static urlpatterns = [ path('', views.home, name='home'), ]+ static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) all works as expected but what I would like to do is to restrict access to the MEDIA_URL (so all uploaded files) to logged in users with a staff role. I have found a lot of examples on how to do it for a traditional view (e.g. linked to a template) but nothing clear on how to do it for the MEDIA files in Django 3. I will certainly create a restricted view but this will not help if all files in the media folder can be accessed. Note: I don't want to have a complex setup to use Apache or … -
How to pass object assignment to a foreign key relationship in REST Framework?
I have two models: class Group(models.Model): name = models.CharField(max_length=50, null=False, blank=False) class User(models.Model): username = models.CharField(max_length=50, null=False, blank=False) password = models.CharField(max_length=50, null=False, blank=False) group = models.ForeignKey(Group, null=False, on_delete=models.CASCADE) And I have serializers for both of them: class GroupSerializer(serializers.Serializer): name = serializers.CharField() class UserSerializer(serializers.Serializer): username = serializers.CharField() password = serializers.CharField() group = serializers.PrimaryKeyRelatedField(queryset=Group.objects.all()) Then in the registration view, I'm trying to automatically create a group when user is registering their account: @api_view(['POST']) def registration(request): # Creates a new group g_serializer = GroupSerializer(data=request.data, partial=True) g_serializer.is_valid(raise_exception=True) group = g_serializer.save() # Creates a new user u_serializer = UserSerializer(data=request.data, partial=True) u_serializer.is_valid(raise_exception=True) user = u_serializer.save() As you can imagine the error I'm getting is that group field for User class violates not null restriction. I tried to fix it by doing u_serializer['group'] = group.id or u_serializer['group'] = group but it throws the following error: TypeError: 'UserSerializer' object does not support item assignment How can I handle this? The new Group object is being properly created and inserted into the db and I need to assign that object to user.group. -
Editing many-to-many field in related model on the admin site
Suppose I have a Person model and Interest model related to each other as Many-To-Many relation (each person can have multiple interest and vice versa), class Person(models.Model): name = models.CharField(max_length=50) class Interest(models.Model): pers_name = models.ManyToManyField(SciAdviser) interest = models.CharField(max_length=50) Further I want to be able to specify Person's Interests on the django admin site. This can be easily done by registering 2 new classes for admin page, class PersonInterestInline(admin.TabularInline): model = Interest.pers_name.through class PersonAdmin(admin.ModelAdmin): inlines = [PersonInterestInline] This allows one to choose Person's Interests from drop-down list on admin page. However, what if I would like to allow users to add new Interest there, the ones which do not exist in the database (yet)? Is there any way to implement this? In particular, django should add new record to the Interest table if and only if the interest entry specified by a user does not exist. Without this requirement I can use the ForeignKey instead of ManyToManyField. However, in this case there will be many duplicating interest fields in Interests. Ideally, I want to use the Interest field for tagging. Maybe I should use a different approach to the problem at all? However, the possibility to add new interests by users … -
Need to reset whole postgres database, want to backup a table in the database
I give up. Migrations are effed up. encountering error after error. I'm so sick and tired of this shit right now. I just want to move on. So I guess it better to wipe all data because of one table is messed up. Is it possible to backup ONE table, not a database, before wiping? And then after import this back to that table? I use postgres db. -
"except ImportError,e:" Syntax Error with Python 3.7
I am working on a Django web project, and after I updated Django to 1.4.22 it gave me this syntax error when trying to run my project: File "/Users/ethanjay/env/py37/lib/python3.7/site-packages/django/core/management/init.py", line 54 except ImportError,e: ^ SyntaxError: invalid syntax I went online to try and fix this, and it seemed that this was a Python Version error, and the solution would be to use Python 2.7 instead of 3.7, yet I've been successfully using a virtualenv with 3.7 up until I updated my Django version. Let me know if I need to be more specific or add any other pieces of information -

Overriding Django User model goes wrong on username field
I am making a personal project in order to learn more and more and even more about Django with some advanced code. In my project, I have substituted a custom User model by the following: (Take into account that I am using REST Framework) class Account(AbstractUser): """Account model. Extends from Django's AbstractUser.""" USERNAME_FIELD = 'email' REQUIRED_FIELDS = ['password'] palta = models.ForeignKey( Palta, null=False, db_column='palta', on_delete=models.CASCADE ) name = models.CharField( max_length=200, null=True ) email = models.EmailField( 'email address', unique=True, max_length=70, null=False, blank=False ) password = models.CharField( max_length=30, null=False, blank=False ) registration_date = models.DateField(null=False, auto_now_add=True) last_session = models.DateTimeField(null=True, auto_now=True) birthday = models.DateField(null=True) exists = models.BooleanField(null=False, default=True) class Meta: db_table = 'accounts' unique_together = ['id', 'palta'] I added the following line in settings.py: # Django's User model override AUTH_USER_MODEL = 'accounts.Account' And my serializer for this class looks like this: class CreateAccountSerializer(serializers.Serializer): """Creates a new Account.""" palta = serializers.PrimaryKeyRelatedField(queryset=Palta.objects.all()) email = serializers.EmailField() password = serializers.CharField() def create(self, data): """Account creation serializer.""" return Account.objects.create_user(**data) Note that I'm trying to use the method create_user(), which is expecting a username. The problem is that I have overridden the username field with just an email field, it means that the email in the registration request is the … -

My custom login form in Django attempts to create a new user rather than log a user in
I set up a custom user class and I'm using all custom user management templates, views, urls, etc... All of them work except my login view. I can get it to work by pulling taking the username and password straight from the request and skipping form cleaning. That however, sounds like a really bad idea. When I try to use forms.is_valid() The function gives me errors indicating it's trying to create a new user rather than log an existing one in. I've been looking around and doing trial and error for a few hours now and I still have no clue why its doing this and why no one seems to be concerned about cleaning their login forms. Here is my login view: def loginView(request): if not request.user.is_authenticated: if request.method == 'POST': form = forms.LoginForm(request.POST) authError = False if form.is_valid(): username = form.cleaned_data.get('username') password = form.cleaned_data.get('password') post = CustomUser.objects.filter(username=username) if post: username = form.cleaned_data.get('username') user = authenticate(username=username, password=password) login(request, user) return redirect('home') else: authError = True print("form failed") #print(form) #print(form.errors) return render(request, 'login.html', context={'form': form, 'form_errors': form.errors, "auth_error": authError}) else: print("get request") form = forms.LoginForm() print(form) return render(request, 'login.html', context={'form': form}) else: return redirect('home') and here is my form: class … -

Here is my settings.py code for gdal. import os if os.name == 'nt': import platform OSGEO4W = r"C:\OSGeo4W" if '64' in platform.architecture()[0]: OSGEO4W += "64" assert os.path.isdir(OSGEO4W), "Directory does not exist: " + OSGEO4W os.environ['OSGEO4W_ROOT'] = OSGEO4W os.environ['GDAL_DATA'] = OSGEO4W + r"\share\gdal" os.environ['PROJ_LIB'] = OSGEO4W + r"\share\proj" os.environ['PATH'] = OSGEO4W + r"\bin;" + os.environ['PATH'] I have a model that has a pointfield. model: class Event(models.Model): user = models.ForeignKey(User, on_delete=models.SET, blank=True) name = models.CharField(max_length=100) category = models.ForeignKey(Category, on_delete=models.CASCADE) location = models.PointField(srid=4326, blank=True) Whenever I try to create an event and set the pointfield value, I get this error: GDAL_ERROR 6: b'Unable to load PROJ.4 library (proj.dll), creation of\nOGRCoordin ateTransformation failed.' Error transforming geometry from srid '4326' to srid '3857' (OGR failure.) -
Django Form wizard - How to save selected items in many to many field
So I have a form divided in two steps using the Django formtools Form wizard. The form is working, the data is being saved, except for the manytomanyfield items. Users can create an Ad which can be filtered by tags. The Tag model is related to the Ad model through a manytomanyfield, however on saving the form, the selected tags are not saved within the Ad model. models.py class Ad(models.Model): title = models.CharField(max_length=200) description = RichTextField() tags = models.ManyToManyField('Tag') class Tag(models.Model): name = models.CharField(max_length=200) views.py FORMS = [ ('title', AdCreateFormStepOne), ('tags', AdCreateFormStepTwo), ] TEMPLATES = { 'title': 'grid/ad_form_title.html', 'tags': 'grid/ad_form_tags.html', } class AdWizardView(SessionWizardView): form_list = FORMS def get_template_names(self): return [TEMPLATES[self.steps.current]] def done(self, form_list, **kwargs): instance = Ad() for form in form_list: instance = construct_instance(form, instance, form._meta.fields, form._meta.exclude) instance.save() return redirect('index') So I guess I still have to handle the manytomany relation in the done method for the AdWizardView. I saw the following question answered but the solution throws an error... 'odict_values' object does not support indexing Does anyone know what I'm missing here? With best regards, -
