How do i change the default primary key in django?
I'm new to learning django. I'm using PostgreSQL as my database. I created an app called gplus and a model I created looks something like this class Account(AbstractBaseUser): email = models.EmailField(max_length=50, unique=True) username = models.CharField(max_length=50, unique=True) first_name = models.CharField(max_length=30) last_name = models.CharField(max_length=30) date_of_birth = models.DateTimeField() I applied the migrations and then wanted to change the primary key field from default 'id' to 'username'. So, in the psql command line I ran the following commands ALTER TABLE gplus_account DROP CONSTRAINT gplus_account_pkey; ALTER TABLE gplus_account ADD PRIMARY KEY (username); ALTER TABLE gplus_account DROP COLUMN id; Then in the models.py, I edited the username field as username = models.CharField(max_length=50, primary_key=true) Now, when I try to apply the migrations, I get the error django.db.utils.ProgrammingError: column "id" of relation "gplus_account" does not exist It seems Django needs to know there is no 'id' field in the table anymore. How can I do that? Thanks -
Connecting to AWS Postgres Instance For Django Backend
I've created a PostgreSQL database on AWS, which I want to use for a Django project. I've modified settings.py so that it has DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql', 'NAME': <db name>, 'USER': <user>, 'PASSWORD': <password>, 'HOST': 'projectdevelopment.foobar.us-east-1.rds.amazonaws.com', 'PORT': '5432', } } Which I would have thought seemed pretty straightforward. Except that when I try to make a migration I get this error: django.db.utils.OperationalError: could not translate host name "projectdevelopment.foobar.us-east-1.rds.amazonaws.com" to address: nodename nor servname provided, or not known The value projectdevelopment.foobar.us-east-1.rds.amazonaws.com has been copied directly from the value under endpoint in the RDS console. Am I missing a setting, or misconfigured? Or both? -
How can I save a UserProfile image (avatar)'s path in the database?
I am having trouble figuring out how I can store a user's uploaded image (their avatar) when they update their profile. The default image I have in the model works, but the update does not give a validationerror, but essentially nothing happens when i submit - the default image remains the same. Here is my code, any understanding of what I'm doing wrong is greatly appreciated. user_profile/views.py def update_user_profile(request, username): args = {} if request.method == 'POST': form = UpdateUserProfile(request.POST, request.FILES, instance=request.user) if request.user.username == username: if form.is_valid(): form.save() return HttpResponseRedirect(reverse('user-profile', kwargs={'username': form.instance.username})) else: raise Http404() elif request.method == 'GET': if not request.user.username == username: raise Http404() else: form = UpdateUserProfile(instance=request.user) else: form = UpdateUserProfile(instance=request.user) args['form'] = form return render(request, 'storytime/update_user_profile.html', args) user_profile/forms.py class UpdateUserProfile(forms.ModelForm): class Meta: model = UserProfile fields = ('first_name', 'last_name', 'email', 'avatar') def clean_avatar(self): avatar = self.cleaned_data['avatar'] try: width, height = get_image_dimensions(avatar) # validate dimensions max_width = max_height = 100 if width > max_width or height > max_height: raise forms.ValidationError( u'Please use an image that is ' '%s x %s pixels or smaller.' % (max_width, max_height)) # validate content type main, sub = avatar.content_type.split('/') if not (main == 'image' and sub in ['jpeg', 'pjpeg', 'gif', 'png']): … -

Edit view on Django not displaying object into page
I got a form page to edit my objects from database, but when I access them with the edit button it goes to the url http://localhost:8000/acoes/edit/1, but I cannot see the object details in the form field. It is just empty as if I was going to create a new object (and it creates if I try) Any suggestion?

Django: Change formset error message(s)
Hello fellow programmers, I would like to change the min_num error message of a formset. My code creates a formset using an inlineformset_factory: formset_clazz = inlineformset_factory(MyParentModel, MyModel, MyModelForm, can_delete=True, min_num=1, validate_min=True) formset = formset_clazz(data=request.POST) print(formset._non_form_errors) if formset.is_valid(): print("yay!") else: print("nay!") return render(request, "mytemplate.html", {'formset':formset}) In the template I render the non_form_errors: {% if formset.non_form_errors %} <ul> {% for error in form.non_form_errors %} <li> {{ error }} </li> {% endfor %} </ul> {% endif %} The min_num validation works as intended and shows the error message Please submit 1 or more forms., when a user removes all forms and submits the formset. My question is: How do I change the error message? From [0] I learned, that it is stored in formset._non_form_errors, but without a way to override the too_few_forms [1] (ctrl-F validate_min) code's message. The BaseFormSet class itself uses ngettext to translate the message, but I do not really want to setup internationalization just for this (or is that easy and straight-forward?). Is there a more convenient way to achieve my goal? [0] Django: Displaying formset errors correctly [1] https://docs.djangoproject.com/en/2.0/_modules/django/forms/formsets/#BaseFormSet -
Creating Calendar table entries, but process currently is very limiting
I'm trying to take info from a few models and generate table entries in the model Calendar. I'd like to perfect this method so that It can be done on any day and will just extend from an entry in the Calendar object that has the future most date. Currently in the view as you can see, it just projects the current objects in the Calendar table, and projects it forward a certain number of days. Which limits me to doing this only on mondays, otherwise it falls out of sync with the TimeSlots table. Also depending on the max_jobs the TimeSlot table entry has I need to create multiple calendar entries... currently it only works with two but I guess I can increase it but the code is very repetative Template: <form action="{% url 'portal:custom_admin' %}" method="post"> {% csrf_token %} <div style="background-color:red; width:15%;"> <button name="submit">Project</button> DANGER!

django duplicates in pagination with order_by() on manytomany field
I am sorting a query on a timefield from a manytomany object but have trouble during pagination. models.py: class Validated(models.Model): job_id_list = models.ManyToManyField(JobId , related_name='JobId', blank=True) class JobId(models.Model): user = models.ForeignKey(User, blank=True, null=True, default=None) job_time = models.DateTimeField(auto_now_add=True) views.py: results_list = Validated.objects.filter(job_id_list__user=request.user).\ distinct().order_by('-job_id_list__job_time') My problem is that pagination is messed up and I get duplicates in my pagination output, even when the query output is ok. (other have this problem too) I tried several solutions but my issue does not get solved as sorting is bases on a field from a many-to-many object order_by('job_id_list__job_time') I was thinking of a work-around through creating an annotation to my model by the use of a Model.Manager. Inside this annotation, i try to add the job_time which is a result of a function inside the model. In that way, the job_time would be easily accessible: for i in result_list: job_time_from_model = result_list[i].job_time I would do this as followed but I don't know how to incorporate the %%function logic%% inside the annotation. Is this even possible in this way or is another approach required? models.py: class ValidatedManager(models.Manager): **%%function-logic%%** def date(self, user, id): xlinkdatabase_validated_object = self.get(id=id) job_id_list = xlinkdatabase_validated_object.\ job_id_list.all().order_by('-job_time') date_added = None for item in job_id_list: … -
How to handle for/if loops from Jinja2 in Django Tempates

Why django ugettext_lazy inside a set doesn't always work?
TL;DR I'm having a hard time to dynamically remove the whole Important dates section from django.contrib.auth.admin.UserAdmin when I take translation into account =( security/admin.py ... from django.utils.translation import ugettext_lazy as _ ... class CustomUserAdmin(UserAdmin): exclude_section_set = {_('Important dates')} ... def _filter_sections(self): result = deepcopy(fieldsets) return tuple( section for section in result if section[title_index] not in self.exclude_section_set ) return result django.po ... #: security/admin.py:17 msgid "Important dates" msgstr "Datas importantes" ... Translation is working as far as I can tell. This piece of code removes correctly the section when my browser uses the en language, but it doesn't when my browser is using the pt_BR language. I have (hopefully) isolated the problem. It seems to be the in operation of the set type using ugettext_lazy instances, but I don't understand the behavior. Results of my python console using pt_BR language: >>> _('Important dates') in {_('Important dates')} True >>> print({_('Important dates')}) {'Datas importantes'} >>> _('Important dates') in self.exclude_section_set False >>> print(self.exclude_section_set) {'Datas importantes'} Results of my python console using en language: >>> _('Important dates') in {_('Important dates')} True >>> print({_('Important dates')}) {'Important dates'} >>> _('Important dates') in self.exclude_section_set True >>> print(self.exclude_section_set) {'Important dates'} What am I missing here?

Google API Discovery Build
I'm having some trouble with the google api discovery build. If I put the credentials from the flow.credentials into the discovery.build I can get the response from drive.files().list().execute(). However, if I put them into a dictionary like so: data = { "token": credentials.token, ...etc... } And then create the credential with: credentials = google.oauth2.credentials.Credentials(data) Then call the: drive = googleapiclient.discovery.build('drive', 'v1', credentials=credentials) list = drive.files().list().execute() I get an error like below: {'client_secret': 'example', 'token': 'example'...} could not be converted to unicode. Any Ideas? Im guessing one of the values is not a unicode? This is the basic example, I'm actually getting the results from the database but the error happens even if I dont save them to the db and just put them into the {}. Thank you, -

I suspect maybe because I'm doing a GET the CLEAN doesn't get recognized? I've spent most of the afternoon playing with variations but no matter what I do CLEAN is just ignored.

Django Website Not Updating
I have created a new html file in the static/partials folder of my project and trying to see it on my Django website. I can edit older html files in that folder and see those changes, but can not see the new html file, which is pretty annoying. In the main urls.py, I redirect the links to pages in the static/partials folder to the base file, which is redirected to a js file to retrieve template information. This is what the js file looks like that redirects links to the partials html pages (the essential parts): x = angular.module('x', []); . . . x.config(['$routeProvider', '$locationProvider', function($routeProvider, $locationProvider) { $routeProvider. when( '/', {templateUrl: '/static/partials/index.html'}). when( '/newpage', { templateUrl: '/static/partials/newpage.html', controller: "ControllerName" }); $locationProvider.html5Mode(true); }]); -
Using Foreign Key on Django model to populate select input

PyCharm debugger disconnects from remote host after short idle time
I've been using the PyDev/PyCharm debugger's remote debugging feature for years, and it's worked just fine. I've been using it for a Django-based project which runs in a Docker container for the last year or so, and it worked just fine with that, too. But ever since a few months ago (possibly due to my code shop's switch to Python 3?), I've had no end of frustration with it because the debugger keeps disconnecting for no reason. I'll be in the middle of a debug session that's going just fine, but then if I let the system idle for about a minute, the debug session suddenly dies, and execution of the request goes on without me. When that happens, I'll see the console output change from: Connected to pydev debugger (build 173.3942.36) To: Connected to pydev debugger (build 173.3942.36) Waiting for process connection... And once this happens, the only solution to get the debugger to reconnect to the running Django server inside my container is to restart gunicorn, either through editing a file to make gunicorn reload itself, or through restarting the gunicorn application with kill -HUP. Further requests made against the server will not trigger any breakpoints unless I … -
Ajax client connecting to a Django (cross domain) works only with JSONP

Delete/Replace aditional items/images when an image is replaced, using an inlineformset
I have 2 models Product and Image: class Image(models.Model): product = models.ForeignKey(Product, related_name='images', on_delete=models.CASCADE) # we need this key to the original image because otherwise we can get/update individual cropped images parent = models.ForeignKey('self', blank=True, null=True, verbose_name='original image', on_delete=models.CASCADE) image = models.ImageField(upload_to=file_upload_to) image_type = models.CharField(max_length=50) The ImageForm is uploaded as Inlineformset in the Product ModelForm. Steps: I upload an image (original) - parent key in the model I crop starting from the original image, 2 other images(base on type) I replace the original Image with another Image (in form) In the database Django (inlineformset)deletes the old original Image record and a add a new record for the replaced Image crop and add in database: if crop_image(disk_path, new_disk_path, size): Image.objects.update_or_create(image_type=type_key, parent_id=parent_id, product_id=product_id, defaults={'image': new_db_path}) My problem is that, when Django change original image by deleting and adding (not updating) I remain in the database with two cropped imaged, linked to the original record that is not there anymore. If Django used an update, my function will work, but it is not. Also 'on_delete=models.CASCADE' doesn't work, because oterwise it should have deleted tem cropped image. So I need somehow do delete this images. -
Syntax for connecting models to admin, Django
I have been learning python for some months, and started tinkering with Django. Before posting this, I read up on the auto-generated 'admin.py'-code on github, as well as googled the matter. It appears my question is a little specific, and I was quite frankly very confused from that specific reading. Thus, I hope asking this adds value to this wonderful community. Question: When connecting a model to the admin page, in admin.py, you first import admin: from django.contrib import admin After this, you import your model. Then, you supposedly connect your model through: admin.site.register(MODEL) What I do not understand is what 'site.register' is. The fact that the line starts off with 'admin.' makes perfect sense, as you are specifying from where the following import (ex. 'admin.function' or 'admin.class') comes from. Had it only been 'admin.somefunctionfromadmin' I would have totally understood this. Now, instead, I am confused as to what 'sites.register' is. Is 'sites' a module, a file, and 'register' a function from within that module? If so, what does that make 'admin'? A package? I have seen lines similar to these throughout Django, and feel a bit confused. Thank you! -
How do I represent two models on the same webpage?
