UNIQUE constraint failed in django test client
I have a code like this inside tests.py: thirduser = User( username = "thirduser", password = "12345678" ) thirduser.save() third_user = Profile( user = thirduser ) third_user.save() it returns the error of UNIQUE... If I remove third_user.save() it works. But when I want to assign it to my project as project01 = Project( user = third_user, title = "prg01", description = "dsc01", category = cleaning, deadline = deadline, date_posted = date_posted, status = OPEN ) project01.save() Then it returns another error of save() prohibited to prevent data loss due to unsaved related object 'user'. Note: The user for project should be from Profile model that I have in my code. and Profile model has a field named user which is from User (from django.contrib.auth.models import User) -
'Update' in model results in overwriting
I have a code here to update a field in database which is null initially. dumlist=['ss','bb'] for ntn in imggetvalues: for datas in dumlist: imgget.update(data=datas) where imgget gives objects of the Django ORM imgget=Model.objects.filter(page_num=3) imggetvalues=[smtng for smtng in imgget] But this code only overwrites the previous entry as the inner loop runs. How can I get 1st value from dumlist to update 1st field in model object and 2nd in 2nd field,considering there are 2 objects? -

How to add custom headers in django test cases?

Django: Cannot reference a fieldname in template which contains a dot
The object which I pass from view to template has a few fields which are dynamically incremented and allocated e.g the object looks like: row = { 'id':id, 'input.object1':obj1 'input.object2':obj2 } I am trying to access the value of "input.object1" as "{{ row.input.object1 }}" in template. but the page does not show anything for this field (same for "input.object2") {% for row in row_list %} <tr> <td>{{ row.id }}</td> <td>{{ row.input.object1 }}</td> <td>{{ row.input.object2 }}</td> </tr> {% endfor %} Is there anyway to access these values in html ? Thanks in advance :) -
Better way of sending bulk requests to a remote API with Django Celery?
I have users table with 24K users on my Django website and I need to retrieve information for each of my users by sending a request to a remote API endpoint. So my plan is to use the Celery periodic tasks with a new model called "Job". There are two ways in my perspective: 1. For each user I will create a new Job instance with the ForeignKey relation to this user. 2. There will be a single Job instance and this Job instance will have a "users" ManyToManyField field on it. Then I'll process the Job instance(s) with Celery, for example I can process one Job instance on each run of periodic task for the first way above. But..there will be a huge amount of db objects for each bulk request series... Both of them seem bad to me since they are operations with big loads. Am I wrong? I guess there should be more convenient way of doing so. Can you please suggest me a better way, or my ways are good enough to implement? -

Deploy elasticsearch + mongodb and django on different machines
I just used elasticsearch integrated with mongodb and django. I am using django-elasticsearch-dsl. I have run successfully on the same machine.

Need Help setting up Database Router for multiple mysql databases
I created a project that has two identical models for work from home(wfh) employees, and work from office (wfo) employees. I want wfh employee data to be stored in 'wfh' database and wfo data in 'wfo' database. Database used is mysql. However I am facing following troubles: 1) Migration fails with error: In allow_migrate() method in Router_name.py, model_name received multiple values. So I had to replace allow_migrate() method with allow_syncdb() which got rid of error and migrations were applied. 2)tables are not generated even though migrations are successful for all databases. Python shell is unable to add new employee entries to database (table does not exist error) 3)Creating superuser, after entering just the username, throws exception for improperly configured database 4)superuser created earlier (just after making project) on trying to login from admin panel gives incorrect credentials message Project Structure Project Folder | +--env | +--multi_db | +--basic_app | | | +--AuthRouter.py | +--DbRouter.py | +--models.py | +--multi_db | | | +--settings.py | +--manage.py settings.py DATABASES = { 'default': {}, 'auth_db': { 'NAME': 'auth_db', 'ENGINE': 'django.db.backends.mysql', 'HOST': '127.0.0.1', 'PORT': '3306', 'USER': '***', 'PASSWORD': '***', # connect options 'OPTIONS': {'init_command': "SET sql_mode='STRICT_TRANS_TABLES'", }, }, 'work_from_home':{ 'ENGINE': 'django.db.backends.mysql', 'HOST': '127.0.0.1', 'PORT': '3306', … -
Adding field to serializer with 2 foreign keys
I have 2 models that look like this: class Topic(models.Model): name = models.CharField(max_length=25, unique=True) def save(self, *args, **kwargs): topic = Topic.objects.filter(name=self.name) if topic: return topic[0].id super(Topic, self).save(*args, **kwargs) return self.id class PostTopic(models.Model): topic = models.ForeignKey(Topic, on_delete=models.CASCADE) post= models.ForeignKey(Post, on_delete=models.CASCADE) If the topic is already in the Topic table, then we return the id of that topic. We do not create another. When a user submits a Post with tagged topics (think of it as hashtags), then if those topics don't exist in the Topic table they will be created along with the relationship in PostTopic That being said, here's how my serializer looks: class PostSerializer(serializers.ModelSerializer): topics = serializers.ListField( child=serializers.CharField(max_length=256), max_length=3 ) class Meta: model = Post fields = ('user', 'status', 'topics') def create(self, validated_data): topics= validated_data.pop('topics') post = Post.objects.create(**validated_data) for topic in topics: topic_id = Topic(name=topic).save() PostTopic(post_id=post.id, topic_id=topic_id).save() return post Currently, my serializer gives me an AttributeError, because topics is not a field in Post. How can I fix this so that I can make it work? If I use PostTopic then how would I get the user to give the actual topics? -

how to check and pass the instance of the user in my form in Django?
Hi I'm trying to create a form that accepts Log from the user however I don't know how to pass the instance of the user. I'm used to creating a CreateView for this, however since I'm planning to use customized widgets and settings, I'm using a modelform to create logs for the user. My question is is this the same way as create view to check the instance of the user? Is it still the same as what I did to my createview which is: def form_valid(self,form) : form.instance.testuser = self.request.user return super().form_valid(form) Or do I have to do something else entirely? Here is my Forms.py: from django import forms from profiles.models import User from .models import DPRLog class DateInput (forms.DateInput): input_type = 'date' class Datefield (forms.Form): date_field=forms.DateField(widget=DateInput) class dprform(forms.ModelForm): class Meta: model = DPRLog widgets = {'reportDate':DateInput()} fields = ['status','login','logout','reportDate','mainTasks','remarks'] Models.py: from django.db import models from profiles.models import User from django.urls import reverse # Create your models here. class Points(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) points = models.IntegerField(default=0, null=False) def __str__(self): return self.user.username class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) image = models.ImageField(default='default.png', upload_to='profile_pics') def __str__(self): return f'{self.user.username} Profile' class Manager(models.Model): manager = models.OneToOneField(User, on_delete=models.CASCADE) def __str__(self): return self.manager.full_name class Member(models.Model): … -

Django Rest FrameWork // Conditional Model of OneToOneField
I'm developing restful API with Django Rest Framework for a statistics homepage for Admin. The service is already in progress, and I attached Django to the database that has already been created. models.py was created through managy.py inspectdb. There are no foreign keys(or OneToOneField) in the existing tables. So I am trying to create a foreign key myself in the generated models.py. But I found a table that inserts PKs of multiple tables in one column. # models.py Amodel(models.Model): consult_id = models.IntegerField(primary_key=True) # number start from 100,000 .... Bmodel(models.Model): note_id = models.IntegerField(primary_key=True) # number start from 1 .... Cmodel(models.Model): consult_note_id = models.IntegerField(primary_key=True) # saved 'consult_id from Amodel' and 'note_id from Bmodel' with unique property. ... what_is = models.CharField(max_length=7, ...) # saved 'consult' for consult table's data and 'note' for note table's data I'm trying to replace that consult_note_id in the Cmodel with OneToOneField for a smoother ORM use. Expected code below. Cmodel(models.Model): consult_note_id = models.OneToOneField(Amodel or Bmodel, on_delete=models.SET_NULL, null=True, blank=True, db_column='consult_note_id') ... what_is = models.CharField(max_length=7, ...)

Django Rest Framework, is it possible to organize uploaded files by associated user?
I'm planning out a backend which takes in an email associated with a file upload. Would it be possible to make the backend create a new sub-folder (with the name being the uploaded email address) in my main media folder every time a file was uploaded with a new email, or put files into the corresponding sub-folder? I've tried to look up any examples of this, but haven't come across any. Thanks! -
