PasswordChangeForm is never valid, error messages always present in template
I'm trying to implement password changing functionality in my Django 2.1.7 webapp. Even when I use a GET request for the change password page, these two errors are present in the template: The two password fields didn't match. Your old password was entered incorrectly. Please enter it again. Additionally, when I POST data with the form, form.is_valid() always returns false, even though I can confirm that the error messages (the same ones listed above) are false. The form page gives no error messages unless I manually put them in. I've tried the solution here and many similar ones. As far as I can tell, my logic is the same. View def change_password(request): args = {} if request.method == "POST": form = PasswordChangeForm(data=request.POST, user=request.user) if form.is_valid(): form.save() # Keep the user logged in after they change their password. update_session_auth_hash(request, form.user) return redirect("manager:profile") else: print("INVALID PASSWORD") print(form.error_messages) else: form = PasswordChangeForm(request.user) args["form"] = form return render(request, "manager/change_password.html", args) Template <head> {% extends 'manager/base.html' %} {% block title %} Change Password: {{ user.username }} {% endblock %} </head> {% block body %} {% if form.error_messages %} {% for error, error_message in form.error_messages.items %} <b>{{ error_message }}</b><br> {% endfor %} {% endif %} <form … -
How to add unique=true in model without overriding parent model's field? Django
I have a User model: class ExtraUser(AbstractUser): is_activated = models.BooleanField(default=True, db_index=True, verbose_name="Is user activated?", help_text="Specifies whether user has been activated or not") email = models.EmailField(unique=True, blank=False, verbose_name="user's email", help_text='please type in your email address') # new class Meta(AbstractUser.Meta): # 103 unique_together = ("first_name", "last_name", ) Is it any way to add “unique=True” attribute to the “username” field in AbstractUser model without overriding it the same way like I did with “email” field??? It will screw autotranslation then… Somewhere in init perhaps? Thank you! -
How can i add a field to my Django model to dynamically filter a dropdown on another field?
I have a created Django-CMS Plugin with a ManytoManyField to another model. When creating the Plugin on the Front-End, i want the user to be able to filter the ManytoManyField list (which might be too long). By the way this future is already on Django admin: class ModelAdmin(admin.ModelAdmin): list_filter = ('field_name', ) form = PartnerLogoTableForm Is it possible to have something similar like that on my cms_plugins.py: class PartnerLogoTablePlugin(CMSPluginBase): model = LogoTablePlugin form = LogoTablePluginForm name = _('LogoTable Plugin') render_template = False search_fields = ('description',) def render(self, context, instance, placeholder): self.render_template = 'aldryn_logo_tables/plugins/%s/logotable.html' % instance.style context.update({ 'object': instance, 'placeholder': placeholder, }) return context plugin_pool.register_plugin(PartnerLogoTablePlugin) models.py: class PartnerLogoTable(models.Model): name = models.CharField(_('Partner name'), max_length=255) image = FilerImageField(verbose_name=_('Image'), null=True, blank=True, on_delete=models.SET_NULL) partner_url = models.TextField(_('Partner url'), null=True, blank=True, validators=[URLValidator()]) is_active = models.BooleanField(_('Is active'), blank=True, default=True) created_at = models.DateTimeField(_('Created at'), auto_now_add=True) updated_at = models.DateTimeField(_('Updated at'), auto_now=True) order = models.IntegerField(_('Order'), null=True, blank=True) class Meta: verbose_name = _('Partner Logo') verbose_name_plural = _('Partner Logos') ordering = ['order'] def __str__(self): return self.name class LogoTablePlugin(CMSPlugin): DEFAULT = 'default' LOGOTABLE_CHOICES = [ (DEFAULT, _('Default')), ] description = models.CharField(_('Description'), max_length=255, null=True, blank=True) partner = models.ManyToManyField(PartnerLogoTable, verbose_name=_('Partner')) logo_per_row = models.IntegerField(_('Logo per line'), default=1, null=True, blank=True, validators=[MaxValueValidator(4), MinValueValidator(1)], help_text=_('Number of logos to be displayed … -
How to download zip file from server side to client side (django to react)
On my django server side, I have a file that downloads some files from s3 and then zips them together. I then want to send that zip file to the client side and download it on client side. However, when ever I try to open the zip file on the client side I get a An error occurred while loading the archive I am running on Ubuntu 14.04 with a django backend and a react frontend. I tried passing the file as a tar file, but that didn't work either. I have also tried many different ways of passing the zip file to the HTMLResponse, but I always get the same error. Right now to try to make it work, I am just trying to download a zip file I have downloaded on my local computer.

DRF DataTables GET Request Is Too Long
I am using DRF to serialize a model, and serve the model to an endpoint. I am using django-rest-framework-datatables to format that endpoint into the JSON DataTables requires with ?format=datatables. I have a large DataTable that I am trying to render, and once I get to a certain number of columns, a nondescript 404 error occurs. The request URL for the ajax data is 2k+ characters long, and I think this is the issue since it's a GET request. How do I get around this limitation without using POST since it's a REST API? -
Parallel Execution of Queries in Python

How do I render a model with a different template based on a model attribute
this seems like a really basic thing, so I'm expecting this to be a straight forward answer... sorry if this is dumb. I have a model called Item. It has a headline, body text, links, etc. However, it also has an attribute 'type' which is either 'video' 'podcast' or 'article'. At the moment, I use a generic class 'DetailView' to render a detail page for Item. The template is called item_detail.html and is passed to the request from DetailView. All I want to do is have the view send a different template based on the 'type' attribute. So if item.type = 'article' render an article template, if item.type = 'video' render a video template. Is this possible whilst still using DetailView? This is what I tried in the view: class ItemDetailView(generic.DetailView): model = Item if Item.type == 'video': template_name = 'curate/item_video.html' This didn't do what I wanted - in fact the template just rendered as normal. Am I missing something? I also considered creating an entirely new model for 'videos' 'podcasts' and 'articles' but I'd rather avoid this and have an 'Item' as a powerful content type on the website. views.py class ItemDetailView(generic.DetailView): model = Item if Item.type == 'video': … -
How should I handle Django Rest Framework Unique Field Hyperlinked relationships?
I'm trying to write a custom update for DRF HyperlinkRelatedModel Serializer. But really I'm just banging my head against a wall. It throws up unique constraint errors.

Querying Querysets in Django? Attempting to return a step and then the sub-steps underneath it
I'm thinking this is actually really intuitive, but I cannot figure it out. So I have a model called SWS_Document. Then I have SWS_Document_Step that has a foreign key to SWS_Document. Following that I have a 3rd model SWES_Step which has a foreign key to SWS_Document_Step. Essentially SWES_Document_Step is a sub-step to SWS_Document_Step. Example. It would be "Mix the butter into the recipe" would be SWS_Document_Step. While SWES_Document_Step__id=1 would be "Place the butter into a microwave safe bowl." SWES_Document_Step__id=2 would be "Microwave the butter for 30 seconds." Those are sub-steps to "mix the butter into the recipe." class SWS_Document(models.Model): machines = models.ManyToManyField(Machine, related_name='SWS_documents') document_description = models.CharField(max_length=150, default="") pub_date = models.DateTimeField(auto_now=True) class SWS_Document_Step(models.Model): STEP_TYPE_CHOICES = ( ('People', 'People'), ('Quality', 'Quality'), ('Velocity', 'Velocity'), ('Cost', 'Cost'), ) document_number = models.ForeignKey(SWS_Document, on_delete=models.CASCADE) sws_sequence_number = models.PositiveIntegerField(editable=True, null=True) class SWES_Step(models.Model): STEP_TYPE_CHOICES = ( ('People', 'People'), ('Quality', 'Quality'), ('Velocity', 'Velocity'), ('Cost', 'Cost'), ) sws_document_id = models.ForeignKey(SWS_Document_Step, on_delete=models.CASCADE, null=True) swes_description = models.CharField(max_length=500) swes_step_type = models.CharField(max_length=8, choices=STEP_TYPE_CHOICES, blank=True) pub_date = models.DateTimeField(auto_now=True) So in my view.py I have taken swsallsteps. def DocumentView(request, document_id): # final goal should be to pass a list full of lists... # e.g. [ #[name1, [hazard1, hazard2], [assessment1, assessment2]], #[name2, [hazard3, hazard4], [assessment3, assessment4]], #] steps … -

Connection between Angular and Django on POST
When I do a PUT or PATCH request from Angular to Django I receive a 200 code response. But really there are no changes in the database. The API is a Django REST API using DRF. When I do any request from Postman, all works fine. But when I try to do the request in Angular, the API response with 200 code but there are no change in the database. The same request with the same params on Angular let headers = new HttpHeaders( { 'Authorization': 'Token ' + this._userService.getToken(), 'Content-Type': 'application/x-www-form-urlencoded' } ); return this._http.patch( this.urlAPI, json , {headers: headers} ); //json is the object that I would to modify Then I tried to debug how is the object that Django receive when I send the data in Angular and in Postman and this is the difference. Probably it's the main fault but I don't know how send the data. If i try to change the Content-Type to JSON, I receive a '400 Bad Request' response. The postman output: <QueryDict: {'address': ['Some Address']} > And the Angular output: <QueryDict: {'{"address":"Some Address"}': ['']} > So I'm really lost. -
Manage.py is exiting without any output
I am attempting to upgrade a django 1.10 project to 2.2. My environment is Ubuntu 16.04 and Python 3.5.2 Django is now 2.2 and is running under gunicorn 1.19 with PostgreSQL and Redis. So far, I have removed all the versions flags from the requirements.txt, and re-installed everything using pip. I'm working in a vagrant environment, so I'm rebuilding the whole vm every time I make any changes to the config. When I try and start Gunicorn it seems to work, but looking at the logs I can see the workers are constantly starting and dying without logging anything either in log files or the console. I'm now trying to run manage.py directly and I see it just exit without any exceptions, crash logs or similar. I know it's at least parsing the settings.py - I can make it crash deliberately and I see the exception as expected. I've tried debugging with pdb - and it leads me to believe that it's crashing trying to import a module, but I'm not getting any information about which module. pdb also suggests that the manage.py is terminating with a sys.exit() - no error code, but I can't get any more information. I've … -

I am running a django graphene GraphQL API in a docker container exposed at port 8080. I have also setup the django-hosts package for subdomains. Now I want them to be accessible locally. It perfectly works when I add each subdomain to my hosts file on windows like this: 127.0.0.1 www.mysite.local 127.0.0.1 api.mysite.local And when I call e.g. api.mysite.local:8080. In that case I would need to add every subdomain to my hosts file, for which reason I was looking at nginx-proxy. So my hosts file now contains: 127.0.0.1 mysite.local For making sure it works I have tried it with a simple static web page like that: version: '3.7' services: nginx-proxy: image: jwilder/nginx-proxy ports: - "80:8080" volumes: - /var/run/docker.sock:/tmp/docker.sock:ro web: image: nginx volumes: - ./html:/usr/share/nginx/html ports: - "8080:80" environment: - VIRTUAL_HOST=mysite.local - NGINX_PORT=80 That perfectly works, but trying that for my django application does not: version: '3.7' services: django: build: context: . dockerfile: Dockerfile working_dir: /app environment: - PYTHONUNBUFFERED=1 - VIRTUAL_HOST=*.mysite.local - VIRTUAL_PROTO=uwsgi ports: - 8080:8080 ... So I have added a wildcard flag such that the nginx-proxy can handle the django subdomains. The domain http://api.mysite.local is not there. What am I missing? -
