Setting up a Postgres DB for Django with Fly.io
I'm a novice trying to spin up my first webapp with a combination of Fly.io, Django, and a postgres DB but I'm having some trouble and can't find an answer in walkthroughs or Q&A. I've set up a simple "Hello world" Django app (models.py is empty so far) and I'm trying to get all the components up and running before I build it out any further. I've successfully deployed my app on Fly.io with no errors I've created a postgres cluster on Fly.io using the instructions here: https://fly.io/docs/postgres/ I've attached the cluster to my app, which generates a DB and sets an environment variable with the appropriate details (username, password, port, host, dbname) I've updated my settings.py file: DATABASES = {} DATABASES["default"] = dj_database_url.config(conn_max_age=600, ssl_require=True) I've added to my fly.toml: [[services]] internal_port = 5432 # Postgres instance protocol = "tcp" # Open port 10000 for plaintext connections. [[services.ports]] handlers = [] port = 10000 I've confirmed I can get into the psql shell with flyctl postgres connect -a MYAPP-pg But unfortunately when I run python manage.py migrate to check that everything is working, I get the following error: File "<my_path>\venv\lib\site-packages\django\db\backends\base\base.py", line 282, in ensure_connection self.connect() File "<my_path>\venv\lib\site-packages\django\utils\asyncio.py", line 26, in … -
How to make case insensetive searcn in Django with Postgres
I have a project with Django, Django REST Framework and PostgreSQL. And my goal to make a search with certain conditions: logical operators (AND, OR, NOT) case insensitive operator like * To search by prefixes. som* -> search for some, somali and so on My first attempt was to use Postgres full search with this type search_type='websearch' It's all good but don't have operator * So I switched to raw type search and my class for search looks like it now class DataSearch(generics.ListAPIView): serializer_class = DataSerializer def get_queryset(self): q = self.request.query_params.get('query') if q: vector = SearchVector('research', 'data', 'research__name') query = SearchQuery(q, search_type='raw') queryset = Data.objects.annotate(search=vector).filter(search=query) else: queryset = Data.objects.none() return queryset Logical operator works, search by prefixes works with :* but I don't know how to make it case insensitive. Is it possible to make this type of search case insensitive? Or maybe there are another option for it? -
comprehension list returns empty list with extracted text
I am using a Django application. And I have a function that returns some extracted text. So this is the method: def total_fruit_cost(self, file_name): self.extract_text_from_image(file_name) fruit_cost_found = [] single_fruit = [fruit for fruit in self.fruit_word] for fruit in single_fruit: if len(re.findall(self.regex_fruit_cost(fruit), file_name)) > 0: fruit_cost_found.append(re.findall( self.regex_fruit_cost(fruit), file_name)) return [item for sublist in fruit_cost_found for item in sublist] and the methhod self.extract_text_from_image(file_name) looks like this: def extract_text_from_image(self, filename): self.text_factuur_verdi = [] pdf_file = wi(filename=filename, resolution=300) all_images = pdf_file.convert('jpeg') for image in all_images.sequence: image = wi(image=image) image = image.make_blob('jpeg') image = Image.open(io.BytesIO(image)) text = pytesseract.image_to_string(image, lang='eng') self.text_factuur_verdi.append(text) return self.text_factuur_verdi the fruit_words: self.fruit_word = ['Appels', 'Ananas', 'Peen Waspeen', 'Tomaten Cherry', 'Sinaasappels', 'Watermeloenen', 'Rettich', 'Peren', 'Peen', 'Mandarijnen', 'Meloenen', 'Grapefruit', 'Rettich'] and the regex: regex_fruit_cost: def regex_fruit_cost(self, substr): return r"(?<=" + substr + r").*?(?P<number>[0-9,.]*)\n" and then I use it in the view like this: if uploadfile.image.path.endswith('.pdf'): content = extract_instance.total_fruit_cost( uploadfile.image.path) print(content) But the result is an empty list:[]. the result has to be: 3.488,16 137,50 500,00 1.000,00 2.000,00 1.000,00 381,25 123,20 2.772,00 46,20 577,50 69,30 I also calling three times: file_name in the method: total_fruit_cost That could be improved.

How to get required response from DRF
I have database which consists of configuration of application.

Chart.js display no data message using django
I have a pie chart that I want to display no data message when there is no data to be shown I have tried the methods here but it seems to stop displaying the chart all together even when there is data. currently if there is no data it shows NAN% the data it based off the user data from a model.

A multipart/form-data with nested serializers and files, DRF raises "The submitted data was not a file. Check the encoding type on the form."

How to prevent djagno from updating certain fields?
I have a model that I use in django admin to keep track of action taken on a task. The model includes a user field to show which user added an action. The issue is when a new task update is added, django overwrite the previous user by the new user. As it can be seen bellow, I do not want to change the user (by field) whenever a new action is created. class Action(models.Model): action = models.ForeignKey(TaskAction, models.CASCADE) by = models.ForeignKey('auth.User', models.CASCADE) timestamp = models.DateTimeField(auto_now_add=True, editable=False) note = models.TextField(blank=True, null=True) def __str__(self): return str(self.action) class Meta: verbose_name = 'Task Action' verbose_name_plural = 'Task Actions' db_table = 'task_actions' -
How to more efficiently test if data anomalies occur in transaction (Django)
I want to test if data anomalies such as dirty read, non-repeatable read, phantom read, lost update and so on occur in transaction. Actually, I used person table which has id and name as shown below. person table: id name 1 John 2 David Then, I tested non-repeatable read with test view below and one command prompt. *During sleep(10), one command prompt updates "David" to "Tom" and commits: # "store/views.py" from .models import Person from django.http import HttpResponse from django.db import transaction from time import sleep @transaction.atomic def test(request): print(Person.objects.get(pk=2)) # "David" sleep(10) # Update "David" to "Tom" and commit by one command prompt. print(Person.objects.get(pk=2)) # "Tom" return HttpResponse("Test") But, every time I test data anomalies, I manually need to run test view and update and commit with one command prompt which takes much time. So, how can I more efficiently test if data anomalies occur in transaction? -
Unable to raise ValidationError in Django form

Django-filter package, filtering by date (using calendar)
I am learning Django and have difficulties with django-filter package. I am creating a NewsPortal as my homework. It shows news and i have to make a filter which could list the news by date. Plus i need to use a calendar to choose a proper date for filtering. Not just to write a date in a form but choose it by using the calendar. The problem is that i am using a django-filter package and it creates its own form. Like this: <form action="" method="get" class="filter_news"> {{ filterset.form.as_table }} <input type="submit" value="Search" /></form> I`ve created a FilterSet: class PostFilter(FilterSet): ... time_add = django_filters.DateTimeFilter(lookup_expr='gte', label='Date') class Meta: model = Post fields = ['title', 'post_author_id__author_id__username', 'time_add'] My model: class Post(models.Model): ... time_add = models.DateTimeField(auto_now_add=True) ... Right now filtering is not working at all and i don`t know how to make it by embedding calendar. Please help me if you can. I am completely stuck. -
Django filtering doesn't work with float field
I'm trying to get some records from the MySQL database but it seems that filtering by float field doesn't work. When I filter just by user_id I receive all records but when I add the value clause just got DoesNotExist exception. I have the following models and query: class Record(models.Model): user_id = models.IntegerField() value = models.FloatField() class User(models.Model): value = models.FloatField() Record.objects.get( user_id=user.id, value=user.value ) user.value variable in the python code is 0.4 (float). The value column in the database is type float unsigned and its value is 0.4. I guess it's something because of the nature of float type but what is the right way to filter by float value using Django models? -
textarea offset when two different textareas are possible at the same location using an EventListener

Enforce JOIN instead of Subquey when using "__in" filter in Django ORM
Task: I want to get all invoices where the project title matches a given string. The Invoice has a foreign key to Project. The problem: I want to use a function for doing the project search so I can recycle and encapsulate this use-caes. To make this happen I have to use the __in operator instead of project__title__icontains=my_str. This will lead to an inefficient subquery. The later will create an efficient JOIN. Code examples I have two custom queryset methods. One lives in Project: def search_title(self, title: str): """ Searches for projects having the given title or at least parts of it. """ return self.filter(title__icontains=title) The second one lives in Invoice: def search_project_title(self, project_title: str): return self.filter(project__in=Project.objects.search_title(project_title)) Any ideas how I can tell the Django ORM that I prefer JOINs over Subqueries? Thx! -
Django - paragraph <p> is not working with autoescape
It seems like <p> is somehow missinterpreted when using Django template with {% autoescape off %}. It doesn't matter, in which place I define <p> - before autoescape tag, after or even inside the content delivered to that section. All other tags (defined inside autoescaped content string) works perfectly, the problem is only with paragraph. But the result is that paragraph is empty: Of course I have tried also variant with defined after autoescape like this: but the result is always the same empty tag. I cannot see any reason why this is happening, I would appreciate any help. Thanks. -

Can we have one model serializer for multiple models having the same fields? Django Rest Framework
I have 5 models with same fields inheriting from a base model. Now for all the five models I am having 5 serializers serializing all the fields for their respective models. An example of the setup is as below base model class BaseModel(models.Model): field 1 field 2 ** model 1** class Model1(BaseModel): field 3 = models.Charfield(choices=CHOICES) model 2 class Model 2(BaseModel) field 3 = models.Charfield(choices=CHOICES) So field3 is common in both the models but have different choices in them hence are placed in different models and not in the base model. serializer class SerialModel1(serializers.ModelSerializer): class Meta: model = Model1 fields = "__all__" class SerialModel2(serializers.ModelSerializer): class Meta: model = Model2 fields = "__all__" So as shown even when the models have the same fields I need to use to different model serializers.

Displaying from models to a template page in django
I want to display the data of models to my template file but it just can't work it doesn't even show an error message, even when I pass a QuerySet of message objects as context to the render function. App Name is CD Here my code models.py from django.db import models # Create your models here. class Task(models.Model): text = models.CharField(max_length = 200) def __str__(self): return self.text views.py from django.shortcuts import render from .models import * # Create your views here. def index(requets): tasks = Task.objects.all() context = {'tasks': tasks} return render(requets, 'CD/home.html', context) my template home.html {% for task in tasks %} <h1>{{task.texts}}</h1> {% endfor %} -
Display bootstrap element in django-forms
I want to use an element of a bootstrap template in my django-form: It's html code looks like this: What approach should I take to load this element in my form using django? So far I have tried this: 1.- Define field: CHOICES = [('1', 'First'), ('2', 'Second')] selector = forms.ChoiceField( required=False, label= "Select software products", choices=CHOICES, widget = forms.TextInput( attrs= { 'class': 'choices', 'role': 'combobox', 'data-type': 'select-multiple' } ) ) 2.- Add to layout: self.helper.layout = Layout( Row(Div(Div('selector'), css_class='form-group')) ) The result is a regular input field: In other elements I just put the css class and it works perfectly but I can't figure out how to do it in more complex objects. Thank you in advance!!
