How to Create and Use New Database for Neo4j Unit Test?
For my Django REST project, I need to perform unit test on my neo4j database to ensure the data outputted is in the correct format. However, I must perform these unit test on a testing database that is different than the actual database. Currently the settings.py is arranged in such a way that the views.py will access the default database. How can I have the Unit test access the test database instead without changing the settings.py? -
What the heck is this programming? [closed]
Firstly I started with java and learnt a bit code and after sometime I say programming career guide videos on Youtube. Someone said C++ is nice or someone said Java and Javascript. Some days later I selected Python for my programming language as it is easy for beginners and can be used in many fields e.g., Machine learning, Web-development, Android or Desktop development and even in hacking (I love Hacking @_@). I started with web-development. I didn't learnt completely and someone other developer said if you want to develop a webapp you'll also have to learn HTML, CSS, Javacript (The language, I hate the most) and also framework like Django. I thought Ohhh..! Ok, What the hell is this. I left taking all tutorials, I was following because of all of that worries, How I'll do this and who'll teach me and stuff like that. After some days I realize its ok man you can do it. I started again and after facing many problems as learnt all from Youtube because I don't have enough money to buy courses. Now with the thank of GOD, I created a web app using Django, HTML, CSS and a little bit of JS … -
How can I pass a string into a the .close() method of the FileResponse object?
I am altering the behavior of the .close() method of the FileResponse object. FileResponse is a subclass of StreamingHttpResponse which is very similar to the HttpResponse object. What I am trying to do is take a string of text, save it into a .docx, send that docx to the browser, then delete that docx. Everything is working great until I try to delete the .docx. It doesn't look like I can delete the file before the response is sent because the response needs the file, but I can't do anything at all after the response has been sent because the view has completed its task and sent a response. A potential solution I have found is to modify the .close() method of the FileResponse object (similar to the HttpResponse object) to delete the file. Great. However, I do not know how to pass the path to the file to the .close() method. This might be an elementary question, but I generally avoid editing built in class methods. Code below. import logging from django.http import FileResponse import os logger = logging.getLogger("django") #editing the default closing behavior of the file response object to delete the file that it just sent. class SendAndDeleteExport(FileResponse): … -
Django Python Makemigrations and Runserver do Nothing
I downloaded a .zip template from github of a blog web app built in django and am trying to deploy it to my local server... I have tried running the following lines in my command line, but am not getting any response back... nothing happens except that it just moves to the next line. Any idea why this is occurring? I am able to create a new project using django, I am able to install requirements via command line, and I can run other python scripts fine.

Creating User using Djoser is not storing data for all fields (
I am using DRF to create a ReST API. I am using Djoser for user management. I am using the default django user model as it serves my purpose.

I need to separate my main App from celery, in different servers. How could i achieve this goal?
Today i have a AWS EC2 instance where i run my main App (Django). I'm using docker to containerize my services, which are: Django, Nginx, Mysql, Redis, Celery.

Why the content of my object disappeares when I submit the form instead of being saved in the database?
I'm trying to create a tweeter app using Django3.2 and Python3.9 and I stumble upon a difficult problem to solve. When I try to save a tweet, it's content disappear. If I manually save the content of a tweet using the Python shell directly, the content is saved properly. However, if I submit the tweet from the /home page or from the /create-tweet/, the id is created but with an empty content. It is not saved in the db.sqlite3 database neither. So it seems that the form is not being submitted properly but I can't figure out why exactly? my file structure is the following: tweeterapp ┣ db.sqlite3 ┣ manage.py ┣ templates ┣ components ┃ ┣ footer.html ┃ ┣ form.html ┃ ┗ navbar.html ┣ pages ┃ ┗ home.html ┣ tweets ┗ base.html ┣ tweeterapp ┣ settings.py ┣ urls.py ┣ wsgi.py ┗ __init__.py ┣ tweets ┣ migrations ┣ admin.py ┣ apps.py ┣ form.py ┣ models.py ┣ tests.py ┣ views.py ┗ __init__.py form.hmtl: <form method='POST'>{% csrf_token %} {{ form.as_p }} <button type='submit' class='btn btn-secondary'>Save</button> </form> home.html: {% extends 'base.html' %} {% block head_title %} Test {% endblock head_title %} {% block content %} <div class='row text-center'> <div class='col'> <h1> Welcome to the … -
How to alter Django widget validation behavior for conditionally required fields?
I have a mixed set of formsets. Let's say that I have formsets A and B, and that there are 3 full forms of type A and 2 full forms of type B all in the same html form. All formsets are submitted (because I want to save all entries), but only one set of formsets is ever validated. I have it all worked out, except for the display of {{ forms.A.errors.val }}. The val field is a TextInput field that is required based on a javascript-created select list at the top where they choose to search using formsets A or B. If they choose A, the forms of formset A are shown and B are hidden. Both are submitted because I want them to be able to switch to their previous entries in formset B when the results are presented. The problem is that when they switch to formset B after seeing the results of the search using A, the "This field is required." error is shown next to any empty val fields. I thought that I'd successfully avoided that field validation... I have tried multiple means of preventing that error from displaying. I tried overriding clean to only … -

How do I keep a list of 100 secret keys safe on heroku (django), to be given out only to people with a secret link/password?
I have 100 signed messages that I want to give out to people on twitter randomly. So I want to be able to give them a password or a link on twitter, and then when they enter that password or click that link they get one specific secret key from my website. Obviously if that link leaks then it's fair game for anyone, but each link would only give them access to one secret signed message. Where can I store this? I wanted to store it in a static file and then serve it to complex urls. Like if they go to mywebsite/123SatoshiGoodPassword or whatever, it gives them the 4th secret signed message, and if they go to mywebsite/928VitalikGoodPassword it gives them the 12th secret signed message. (I'm doing this so they can submit an ethereum transaction for a free mint of a token or whatever by the way. They can copy the signed message to send with their transaction or I can use the link to prompt them to submit it on their own. I already have that part worked out.) I don't really want to mess with database stuff as I'm new at all of this. I was … -
How to best submit multiple Django formset_factory forms at once?
This is probably too broad/complex of a question for stack, but I had to go through the process of asking this to clarify my thoughts. I'm very open to suggestions on how to break it up or narrow it down. ATM, I'm not sure how to do that without all this context... I'm fairly new to Django, and I just finished a proof of concept advanced search page that took 2 weeks for me to get working how I want - and it works (pretty well, in fact), but it's really kludgey, and now that I have the proof of concept working, I'm interested in learning how to do it properly, and am looking for suggestions on how to refactor this to make it more straightforward. To summarize the functionality, the interface allows the creation of a complex search query using a dynamic hierarchical form. It does this (currently) for 1 of 2 output formats (which is effectively results in the rendering of a join of 5 or 6 tables in the model, depending on the selected output format), but it submits all the hierarchies and performs the search on the selected one. Here's a gif demo of the interface, … -
media file not found in a simple django-admin application
I have seen many questions here regarding media files in Django, but honestly I can't find a valid solution for my problem. So I have decided to streamline the environment to a very simple application. You can find it here: github project I have created a project with django-admin and I called 'documents' and then I have created an app called 'docs'. Then I defined a simple class: def get_path(instance, filename): fn, ext = os.path.splitext(filename) ts = str(int(time.time())) return os.path.join('{}_{}{}'.format(fn, ts, ext)) class doc(models.Model): doc_name = models.CharField(max_length=30, verbose_name=u"doc name", help_text=u"name of the doc") doc_document = models.FileField(upload_to=get_path, verbose_name=u"document", help_text=u"document") class Meta: unique_together = ("doc_name", ) def __str__(self): return f"{self.doc_name}" This changes the filename and it adds a timestamp. I also changed the urls.py file adding the following: path(r'', admin.site.urls), Now the question is: without using MEDIA_URL and MEDIA_ROOT is it possible to make this working? I have tried to add a files and it works: and it properly save the file in the root of the project. But when I go to the link and click I am getting the following: Now is it possible to know where is it looking for the file? Do you think that adding MEDIA_URL and … -

I tried logging error it was - 2021-07-09T15:43:59.937940+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/admin" host=examtaker-001.herokuapp.com request_id=b3758753-7826-49b6-b22d- c5b1aba1b903 fwd="223.233.68.190" dyno= connect= service= status=503 bytes= protocol=https 2021-07-09T15:44:00.824183+00:00 heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/favicon.ico" host=examtaker-001.herokuapp.com request_id=8085f766-548e-4dde- 852f-8ae40db54afa fwd="223.233.68.190" dyno= connect= service= status=503 bytes= protocol=https I dont really know where the problem is, Exam- Exam- settings.py urls.py wsgi.py main- migrations static- js css admin.py urls.py views.py apps.py templates- index.html manage.py Procfile requirements.txt This is my directory. Inside my Procfile - web: gunicorn Exam.wsgi --log-file- In settings.py - import django_heroku BASE_DIR = Path(__file__).resolve().parent.parent ALLOWED_HOSTS = ['examtaker-001.herokuapp.com', '127.0.0.1'] MIDDLEWARE = [ #other defaults 'whitenoise.middleware.WhiteNoiseMiddleware', ] STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles') STATIC_URL = '/static/' django_heroku.settings(locals()) Rest most of the things remain default. Not sure but I think problem is with BASE_DIR. Any help would be appreciated.
