Overriden templates aren't rendered in production
I've overriden Django-allauth templates in my Django project just creating a new folder "account" in templates folder. This works during deployment on Windows but when I moved the project to DigitalOcean VPS, it is looking for old templates (in allauth app) so I see old styled allauth pages. This is the structure: firstapp\ authapp\ templates\ account\ email.html login.html anotherapp\ I tried to switch allauth apps and my authapp in INSTALLED_APPS but it doesn't seem to work. And this is my settings.py INSTALLED_APPS. INSTALLED_APPS = ( 'django.contrib.auth', 'mainapp', 'django.contrib.admin', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.sites', 'django.contrib.staticfiles', 'crispy_forms', 'super_inlines', 'django_tables2', 'quizzesapp', 'ordersapp', 'django_extensions', 'authapp', 'allauth', 'allauth.account', 'allauth.socialaccount', 'allauth.socialaccount.providers.google', 'allauth.socialaccount.providers.facebook', 'languagesapp', 'widget_tweaks', 'localflavor', 'paypal', 'paypal.standard.ipn', 'nested_inline', 'django_forms_bootstrap' ) What do you thing I should do?

How to insert multi data form to database
I'm trying to insert some multi data to database with django. (I'm totally new to Django, thus, please have mercy :) ) My model is as follows : class Files(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) file_type = models.ForeignKey(to=FileType) file = models.FileField(upload_to='media/%Y/%m/%d/', blank=True) def __str__(self): return self.file_type.name The view where I fetch the data is as follows : def save_user(request): user = json.loads(request.POST.get("user")) for file_key in request.FILES.keys(): file = Files() file.file_type = FileType.get_by_key(file_key.split('/')[1]) file.file = request.FILES[file_key] file.save() return HttpResponse("User saving...") And the data that I get in request is as follows : request.FILES <MultiValueDict: {'file/ID_CARD': [<InMemoryUploadedFile: check.png (image/png)>], 'file/STATUTES': [<InMemoryUploadedFile: pictures.xlsx (application/vnd.openxmlformats-officedocument.spreadsheetml.sheet)>]}> and user {'companyName': 'Autralis', 'btwNumber': '84515', 'address': 'Hundelgemsesteenweg 575', 'country': 'Belgium', 'zipcode': '9820', 'place': 'Merelbeke', 'phone': '+32 486386069', 'mobilePhone': '+32 486386069', 'firstName': 'Maida', 'lastName': 'Mesanovic', 'email': 'maida@autralis.com', 'userName': 'Maida', 'password': '123', 'confirmPassword': '123', 'files': [{'file_type': 'LETTER_HEAD', 'values': {'active': False, 'fileName': 'Blank letterhead', 'file': None}}, {'file_type': 'COMPANY_PICTURE', 'values': {'active': False, 'fileName': 'Company photo', 'file': None}}, {'file_type': 'ID_CARD', 'values': {'active': True, 'fileName': 'check', 'file': {}}}, {'file_type': 'STATUTES', 'values': {'active': True, 'fileName': 'pictures', 'file': {}}}], 'terms': True, 'emailNotifications': True, 'smsNotifications': True} How can I add it to the database? -
Is it possible for DRF ValidationError to skip force_text?
it is possible to return json directly in error message through ValidationError? Example: { "uncompleted_tasks_error": [ { "This operation cannot be completed because there are uncompleted tasks.": [ { "id": 1, "description": "Fill in info", "completed_at": null }] } ] } Currently, ValidationError returns "None" instead of null, as it uses force_text to convert serializer.data to JSON. -

'Manage.py behave' not recognised as command in Django project
I've had to clone a repository involving a django project. This is my first time using django and the project is configured a bit differently than what a normal django project would be. For instance it has a settings folder with a local.py file that contains a Local(Dev) class. I have installed behave_django, however when I run the command 'manage.py behave' it says that the command is not recognised. Therefore I believe that whilst I have added INSTALLED_APPS = ('behave_django',) to the local.py file it is not getting recognised. I have tried adding it outside the class and within. Is there a way I can run a script to check my list of installed_apps, etc. Also I am new to python and the configuration side has gotten me a bit confused. -

Django - calling custom update behaviour when overriding its behavour
What I am trying to do is best described by example. Consider the following: class MyModel(model.Models): # core fields objects = QuerySetManager() class Meta: managed = False db_table = 'my_model' class QuerySet(QuerySet): def update(self, *args, **kwargs): if something_special: # handle that special case else: # call custom update The entire question is how I can call the custom update method using *args and **kwargs. I tried super(self.Model, self).save(*args, **kwargs), but I end up with 'QuerySet' object has no attribute 'Model' error (which is not surprising). Any help on what the correct syntax is? -
Django : One model has two foreign keys is this the right approach in this case
I am currently learning about Django Models. Here is my current situation. I have three models 1-Patient_Names 2-Patient_Responses 3-Doctor_Questions Now here is the relationship there will be multiple patients which will be represented by the model Patient_Names. Now each patient will have specific responses to the questions asked by a doctor these responses are represented by the model Patient_Responses. Because of this the Patient_Responses model will have a field that is a foreignKey to the Patient_Names model.Also since the responses will be for the questions from the model Doctor_Questionsthe Patient_Response has another field that is foreignKey to the model Doctor_Questions. Is this the right approach ? Can a model have two foreign keys? Patient_Names Doctor_Questions | | |---------Patient_Responses -------| | pname = models.ForeignKey(Patient_Names) doctor_questions = models.ForeignKey(Doctor_Questions) -
Clustered foreign key Django
I'm currently working on an existing set of models, with an existing database that suffers from some inconsistencies of data. To visualize, we have tables: A B AtoB FlatTable FlatTable can contain links to A and B individually. As you might guess, this construction allows linkage between an A and a B in FlatTable that's not defined in AtoB. I do not want (or have the opportunity) to change the application completely, I just want to disable improper linkage. A solution would be to create a clustered foreign key which links FlatTable(A,B) to AtoB(A,B). AFAICS https://docs.djangoproject.com/en/1.10/ref/models/fields/#django.db.models.ForeignKey doesn't supply this functionality. I could do a lookup for each insert and such, but this creates all kinds of edge cases that should ideally be covered as well (e.g. updates on A, B, AtoB themselves). I'm still not a veteran in Python / Django and hope that someone who is might know the best way to go here. -
object of type 'NoneType' has no len() - Editing Form
I have a Profile model which has a Foreign key to the user model. I've created an 'edit profile' view which allows users to update profile information. One of those fields being an image field (Hosted with cloudinary). Since changing this field to a Cloudinary field i seem to be having issues with newly created profile objects when the profile doesn't have an image uploaded. However, if the user HAS a profile image i can load the 'edit_profile' view no problem. I've narrowed it down to be the image field as when i remove the field it works no problems. Despite the traceback not being very helpful. Here is my edit_profile view. @login_required def edit_profile(request): if request.method == 'POST': user_form = UserForm(request.POST, request.FILES, instance=request.user) profile_form = ProfileForm(request.POST,request.FILES, instance=request.user.profile) if user_form.is_valid() and profile_form.is_valid(): user_form.save() profile_form.save() messages.success(request, "Successfully Updated") return redirect('profile:edit_profile') else: messages.success(request, "Please correct the below info") else: user_form = UserForm(instance=request.user) profile_form = ProfileForm(instance=request.user.profile) return render(request, 'profile/edit.html', { 'user_form': user_form, 'profile_form': profile_form }) I have two forms, one for the user model which allows the user to update first name, last name and email. Then the profile form, which allows to update the additional fields. I think i need to add … -

Django- duplicate inserts into the choices list of MultipleSelect field in the form
class Form(django_forms.Form): fields_choices = [ ('ID'), ('Name'), ] required_fields = django_forms.MultipleChoiceField() def __init__(self, *args, **kwargs): self.fields_choices.insert(1, 'x') super(Form, self).__init__(*args, **kwargs) self.fields["required_fields"].choices\ = tuple(self.fields_choices) As you could see from the above, I insert one more field into the choices. But if I refresh the form view, there would be two 'x' in the choices. And refresh agagin, one more 'x'. I expect it should be always just one 'x' in the choices. -

How to extract Django Form errors message without the HTML tags
I need to extract the messages and field.
