Django REST Framework; Problems serializing User model with 'groups' field

Single model dynamic database settings in Django
For example assume that I have 100 clients who uses WordPress and I have to write a service in Django which should return list of posts from WordPress's MySQL DB. The problem is 100 clients are having different database connection settings. I know that I can use DatabaseRouter to switch databases which are already loaded in settings. But I don't know how to make a singe model class to use different database settings. I have tried mutating settings. I also tried mutating model's app_label. But I later understood that mutating anyting in Django is meaning less. My Requirements I want to create a model and dynamically change database connection. List of connection can be in a managed database table. But I don't want to unnecessarily load all the connection settings or create multiple models. -
UpdateView restrict to current user
Hello everyone I new to django and trying to make a page where a user can edit their profile. I've managed to make that happen, but the problem I have is that anyone can edit whatever profile they like. What is the way to check if the current request.user is the same that will edit the model user? This is my view: class UpdateProfile(UpdateView): model = User form_class = MemberProfileForm template_name = 'home/member_profile_update.html' slug_field = 'username' slug_url_kwarg = 'slug' Forms: class MemberProfileForm(ModelForm): class Meta: model = User fields = ('first_name', 'last_name', 'email', 'bio') def save(self, user=None): user_profile = super(MemberProfileForm, self).save(commit=False) if user: user_profile.user = user user_profile.save() return user_profile I am extending the User Model like this: class User(AbstractUser): bio = models.TextField(max_length=500, blank=True) phone = models.CharField(max_length=30, blank=True) location = models.CharField(max_length=30, blank=True) birth_date = models.DateField(null=True, blank=True) www = models.TextField(max_length=60, blank=True) twitter = models.TextField(max_length=30, blank=True) facebook = models.TextField(max_length=30, blank=True) google = models.TextField(max_length=30, blank=True) My URL looks like this: url(r'^members/update/(?P<slug>[\-\w]+)/$', views.UpdateProfile.as_view(), name='update_user'), If you can redirect me to some guides or documentation for my case it will be awesome. -
How to retain user input on a regular form in Django?
It was my intention to use a Django form as a data filter, at present there are 3 filters: Label, Platform, and Category. The problem I am running into is that I cannot for the life of me retain the data after submission. Meaning that if I filter on Platform 1 and Platform 2, after submission it will revert back to all platforms (the default setting). I have found some similar questions where a ModelForm is used, but considering my data, a ModelForm is not suitable. My (simplified) code: # forms class PlatformsFilter(forms.Form): Platforms = forms.ModelMultipleChoiceField(widget=forms.CheckboxSelectMultiple() Categories = forms.ModelMultipleChoiceField(widget=forms.CheckboxSelectMultiple() Labels = forms.ModelMultipleChoiceField(widget=forms.CheckboxSelectMultiple() # views def platforms(request) platformfilter = PlatformsFilter() if request.method == 'POST': Platforms = Platform.objects.filter(id__in=request.POST.getlist('Platforms')) platformfilter = PlatformsFilter(request.POST) ## Some minor computations based on data context = {'platformfilter': platformfilter} return render(request, 'analytics/platforms.html', context) # template <form action="" method="POST"> {% for field in platformfilter %} <div class="someattribtues"> {{field}} </div> {% endfor %} <input class="btn btn-block btn-primary" type="submit" name="apply_filters" value="Filter" /> </form> -
Comparing a database field with date

Count on multiple fields in Django querysets
I have a model representing a transaction between two users, like this: class Transaction(models.Model): buyer = models.ForeignKey(User) seller = models.ForeignKey(User) product = models.ForeignKey(Product) I would like to get the number of transactions for each user (either as a buyer or a seller). If a I want to count on only one field, I can just do : Transaction.objects.values('seller').annotate(Count('seller')) but I can't manage to do it on two fields at the same time in 1 query. Is there a way to do that ? Thanks -
Django models ForeignKey return IDs
I have been trying to search forums to get an answer for this, but it seems like its a bit tricky to search. I have the following model which is pulling users from django User table: class trendingidea(models.Model): iname = models.CharField(unique=True, max_length=15) idea = models.TextField(unique=True) submittedon = models.DateTimeField() support = models.PositiveSmallIntegerField() readbyadmin = models.BooleanField() feasibilitycheck = models.BooleanField() submittedby = models.ForeignKey(User,related_name="submitted_by") assignedto = models.ForeignKey(User, blank=True, null=True, related_name="assignedto") However when i query the database and pull the information: ti=list(trendingidea.objects.values()) print(ti) [{'readbyadmin': False, 'id': 1, 'idea': 'cisco', 'feasibilitycheck': True, 'submittedby_id': 1, 'support': 1, 'submittedon': datetime.datetime(2017, 11, 6, 11, 8, 10, tzinfo=<UTC>), 'iname': 'cisoc', 'assignedto_id': 1}] in place of submittedby and assignedto it gives me submittedby_id': 1 and assignedto_id': 1. I wanted the usernames and not their IDs. is there a way to achieve this? -

Django different timezones in same application
I am working on a Django application on Leave Management, in which there are employees from different countries. I am storing the data of the time, when the leave is created, into DB. Now, I want this datetime that is being inserted into DB, to be the current local time of the location where that particular employee is working at. For example, let us suppose Mr. X is working at India and Y is working at Newyork. If X applies for a leave, I want it to be created at local time (created_at= what-so-ever time it is in India) and when Y applies for a leave, I want it to be created_at=what-so-ever time it is in Newyork. As of now, whatever I am inserting into DB, it is getting inserted as UTC time only. How to resolve this issue? I am trying to achieve something like this.. But it is always UTC. userid = employees.objects.get(emp_id=request.user.username) if employees.objects.get(emp_id=request.user.username).emp_loc == 'IND': tzone=pytz.timezone('Asia/Calcutta') elif employees.objects.get(emp_id=request.user.username).emp_loc == 'MLA': tzone=pytz.timezone('Asia/Manila') elif employees.objects.get(emp_id=request.user.username).emp_loc == 'MPLS': tzone=pytz.timezone('CST6CDT') timezone.activate(pytz.timezone(tzone)) tnow=timezone.localtime(timezone.now()) if request.POST['action'] == 'Save changes': new_leave = leave.objects.create(employee=employees.objects.get(emp_id = userid.emp_id), start_date=sdt, end_date=edt, ltype=ltyp, message=des, date_created=tnow) new_leave.save() Badly in need of help..... :( Thanks in advance......... :) -

Why aren't the images of an inlineformset_factory being saved?
I have two models: Profile and CredentialImage. I am trying to allow each Profile to upload, optionally, up to 5 maximum images(CredentialImage).

Django query using datetime flter
In my (Post) model I have published = models.DateField(null=True) My urls include the year/month/day eg /post/category-1/2017/11/06/some-post/ which I am capturing through kwargs in my urls.py In my view my query is model = Post.objects.get(slug=kwargs['slug'],published__year=kwargs['year'], published__month=kwargs['month'],published__day=kwargs['day']) However, this is not working. The only date element which works is for year. I've read some posts here which talk about unsetting USE_TZ in settings.py which is obviously not a solution. I have tried using a DateTime field as well, but that makes no difference. Any help much appreciated. -

Hopefully a simple one, but I can't find what's wrong myself. I have a simple blog app, and I can display the posts titles, in a weird format, but can't pull through the posts body/text - all I get is a blank row. /models.py from django.db import models from django.utils import timezone class Post(models.Model): title = models.CharField(max_length=200) body = models.TextField() pub_date = models.DateTimeField(default=timezone.now) def __str__(self): return self.title /views.py from django.shortcuts import render from .models import Post def index(request): posting = Post.objects.filter() context = { 'posting':posting, } return render(request, 'posts/index.html', context) /templates/posts/index.html <li>{{posting}}</li> <li>{{posting.body}}</li> <li>test text</li> The output to the page is similar to (apologies not exact due to html formatting, but note blank middle line) : QuerySet [Post: First Post>, Post: Second Post>, Post: Third Post>]> test text Thank you. -
Testing django with jquery on the page for empty select fields?
I have been using the following test for the django admin and it has been working really well. Recently I added django-smart-selects to the project and the chained selects do not have options and are empty. def test_invalid_duration_entry(self): '''Ensure error if duration is greater than 24''' response = self.app.get( reverse('admin:entries_entry_add'), user=self.super_user ) form = response.form form['date'] = '2017-11-03' form['project'] = self.project.id form['user'] = self.user.id form['task'] = self.task.id form['duration'] = '24.25' response = form.submit() self.assertEqual( response.status_code, 200 ) self.assertFormError( response, 'adminform', 'duration', 'Ensure this value is less than or equal to 24.' ) When I inspect the value is empty: ipdb> form.get('user') <Select name="user" id="id_user"> ipdb> form.get('user').options [] ipdb> form['user'] = self.user.id *** ValueError: Option 14 not found (from ) jquery is adding the options when the project field is changed. How can I test this now. -
CORE issue for specific type of url .AJAX [duplicate]
This question already has an answer here: Why does my JavaScript get a “No 'Access-Control-Allow-Origin' header is present on the requested resource” error when Postman does not? 31 answers While making ajax call I am getting below error . Get request to "http://*****/api/profile/2" is not working , however a GET request to "http://*****/api/profile/" is working fine(The diff is adding 2 at last" . My web api server is configured to handle CORE . Failed to load http://*****/api/profile/2: Redirect from 'http://*****/api/profile/2' to 'http://*****/api/profile/2' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access. Code: $.ajax({ type: 'GET', url: 'http://*****/api/profile/2', success: function(profiles){ $.each(profiles,function(i,profile){ Alert("Success"); }); }, -
Django: DateTimeField taking UTC format only, not others
The time that is being inserted in database is default UTC, not the timezone based time..I do not understand why is this happening, even though I am particularly specifying, in the query, the time that I want to be inserted. In my Model I have class leave(models.Model): date_created = models.DateTimeField(auto_now_add=True) In my settings I have TIME_ZONE = 'UTC' USE_I18N = True USE_L10N = True USE_TZ = True In my views i am setting timezone based on employee country if employees.objects.get(emp_id=request.user.username).emp_loc == 'IND': tzone=pytz.timezone('Asia/Calcutta') elif employees.objects.get(emp_id=request.user.username).emp_loc == 'MLA': tzone=pytz.timezone('Asia/Manila') elif employees.objects.get(emp_id=request.user.username).emp_loc == 'MPLS': tzone=pytz.timezone('CST6CDT') And then I am creating leave and updating timezone based on country new_leave = leave.objects.create(employee=employees.objects.get(emp_id = userid.emp_id), start_date=sdt, end_date=edt, ltype=ltyp, message=des,date_created=datetime.now(tzone)) new_leave.save() Thanks in Advance.
