custom size of field in crispy form django not working
i want to display a form to create posts. i use crispy-form and it currently displays: with html template: {% extends 'blog_app/base.html' %} {% load crispy_forms_tags %} {% block content %} <div class="content-section"> <form method="POST"> {% csrf_token %} <fieldset class="form-group"> <legend class="border-bottom mb-4">Create Post</legend> {{ form.media }} {{ form|crispy }} </fieldset> <div class="form-group"> <button class="btn btn-outline-info" type="submit">Post</button> </div> </form> </div> {% endblock %} i want to increase size of the title box and reduce size of the content box so that i fits the content section. what i tried: in template, display each field as crispy field with specified css class: {% block content %} <div class="content-section"> <form method="POST"> {% csrf_token %} <div class="form-group col-md-8"> {{ form.title|as_crispy_field }} </div> <div class="form-group col-md-8"> {{ form.content|as_crispy_field }} </div> <div class="form-group"> <button class="btn btn-outline-info" type="submit">Post</button> </div> </form> </div> {% endblock %} in form class, set helper and layout: class PostCreateForm(forms.ModelForm): class Meta: model = Post fields = ['title', 'content'] def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.helper = FormHelper() self.layout = Layout( Field('title', id="form-title", css_class="col-md-8", name="title"), Field('content', id="form-content", css_class="col-md-8", name="title")) in both ways, nothing changes. can someone give me a pointer? -
Calling FileField objects in template renders incorrect path
I've implemented a FileField model in my project. I can successfully upload svg files and they save to the desired location. Within my project, I make heavy use of user uploaded images (JPGs) and they save to the correct location and I can display them in my templates with no issue. However, when I upload an svg to the FileField and then attempt to display it within the template, the link is broken. The problem is that the correct file path isn't being set within the html Template <img src="{{ account.image }}" /> It should point to the following path: localhost:8000/media/Users/jimmy/file.svg But it resolves as the following, which is incorrrect: localhost:8000/profile/settingspage1/Users/jimmy/file.svg Essentially, I've I manually append '/media' to the filepath within the template, it works, but I shouldn't have to do this. The filepath should resolve correct. <img src="/media/{{ account.image }}" /> Any thoughts on what setting could be preventing only filefields from resolving to the correct path within my media folder? Thanks! -
django removes "is_staff" permission if I try to login
I have a pretty strange situation within my django project. I have a LoginForm where a user can log into the website. I am using django 3.2.12 with some other libraries like django-crispy-forms and so on. I implemented django-crowd-auth so that users can access the page with crowd. I made the neccessary configurations in settings.py and the app is running without any issues. Afterwards I gave my existing user is_staff and is_superuser permissions to access the django administration. I did it like this: python manage.py shell >>> from django.contrib.auth.models import User >>> user = User.objects.get(username="<myuser>") >>> user.is_staff = True >>> user.is_superuser = True >>> print(user.is_staff) True >>> print(user.is_superuser) True >>> save() After that I restart my django app the following way: sudo <path_to_conda_env_python>/python manage.py runsslserver --certificate <crt-file> --key <pem-file> 0.0.0.0:88 If I try to log into the django administration panel with the user which I just gave the permissions I get the error "Please enter the correct username and password for a staff account. Note that both fields may be case-senitive" Returning to the django shell gives me this output python manage.py shell >>> from django.contrib.auth.models import User >>> user = User.objects.get(username="<myuser>") >>> print(user.is_staff) False >>> print(user.is_superuser) False It seems … -
Getting Bad Gateway and Connection reset by peer using asyncio + aiohttp
Is there some async expert with sharp eyes around? I am using asyncio (Python 3.9) with aiohttp (v3.8.1) to fetch multiple urls asynchronously through a proxy, but this implementation seems to fail pretty often throwing reset by peer and Bad Gateway errors. The same proxy works well using Scrapy spiders so there must be something wrong with my async implementation. My code: from asgiref.sync import async_to_sync import asyncio import aiohttp async def async_fetch_url(session, url: str, method: str = "get"): async with getattr(session, method)(url, proxy="https://someproxy.com/") as response: return await response.json(content_type=None) async def my_async_fetch(urls: list, method: str = "get"): async with aiohttp.ClientSession(connector=aiohttp.TCPConnector(force_close=True)) as session: return await asyncio.gather(*[async_fetch_url(session, url, method=method) for url in urls]) def my_sync_func(): urls = [ 'https://somesite.com/1', 'https://somesite.com/2' ] result = async_to_sync(my_async_fetch)(urls) Error logs: [2022-04-28 21:47:28,576: ERROR/MainProcess] ???[???]: [Errno 104] Connection reset by peer [2022-04-28 21:47:28,576: ERROR/MainProcess] ???[???]: Traceback (most recent call last): File "/app/cubist_backend/helpers.py", line 176, in async_fetch_url async with getattr(session, method)(url, **kwargs) as response: File "/usr/local/lib/python3.9/site-packages/aiohttp/client.py", line 1138, in __aenter__ self._resp = await self._coro File "/usr/local/lib/python3.9/site-packages/aiohttp/client.py", line 535, in _request conn = await self._connector.connect( File "/usr/local/lib/python3.9/site-packages/aiohttp/connector.py", line 542, in connect proto = await self._create_connection(req, traces, timeout) File "/usr/local/lib/python3.9/site-packages/aiohttp/connector.py", line 905, in _create_connection _, proto = await self._create_proxy_connection(req, traces, … -

How to resolve Key Error Exception when accessing dictionary key inside an if statement
I'm currently developing EV calculator using python and django. I get a key error exception when trying to access a dictionary key in an if statement inside a function. To break it down, my calculator function does the following, prompts the user for four input values, wager_amount, odd1, odd2 and odd_to_bet/back_odd, based on values user has entered, the function will output expected value or ev in jinja html. Something to note is, odd_to_bet/back_odd must either be equal to odd1 or odd2, if odd_to_bet/back_odd is either not equal to odd1 or odd2, the function has an else block with a message to tell the user to Please, check the odds again for any typo error!. An example: lets say the user inputs the following values from html form wager_amount = 10 odd1 = 1.54 odd2 = 2.47 odd_to_bet/back_odd = 1.54 This works fine, i'm able to display output without issues the key error exception arises when the user inputs and submits odd_to_bet/back_odd a value not either equal to odd1 or odd2. wager_amount = 10 odd1 = 1.54 odd2 = 2.47 odd_to_bet/back_odd = 1.52 My expected output should be "Please, check the odds again for any typo error!." displayed in the html. … -

Multiple Git push in one command
I've an application that requires to run git add/commit/push on each single file i'd like to push, in order to trigger a Gitlab Job on each. My problem is that git is actually taking many time to do the git push command. Here are the commands i'm using: git add myFile.json git commit myFile.json -m "commitMessage" variable1 = git rev-parse HEAD # Storing last commit hash into a variable # Pushing only one specific commit to (maybe) make it faster git push $variable1:master What i'd like to do is to make the whole process "faster". What i've thought about: Doing multiple pipeline triggers using only one git push (maybe by running the pipeline on each commit instead of each push), but it doesn't seem possible. Doing multiple pushes in one git push command, so it doesn't have to reload some of the git push init operations before each file pushed (i have no idea on what is happenning during the git push process, so that idea may be wrong) Does anyone has an idea on how to make this process faster, by using one of my ideas, or even a brand new one from you ! Thanks in advance ! -

Django serializer: class LocationList(generics.ListAPIView): model = Homes queryset = Homes.objects.all() serializer_class = LocationSerializer API url: HTTP 200 OK Allow: GET, HEAD, OPTIONS Content-Type: application/json Vary: Accept { "type": "FeatureCollection", "features": [ { "id": 7, "type": "Feature", "geometry": { "type": "Point", "coordinates": [ 19.2800748, 50.2004355 ] }, "properties": { "property_type": 1, "name": "Zagłoby", "surface": 140.0, "price": 5600000.0, "home_number": "11", "street": "Zagłoby", "post_code": "43-600", "city": "Jaworzno", "country": "Polska", "lat_maps": 50.2004355, "lng_maps": 19.2800748, "add_date": "2022-04-17T15:05:18.274352Z", "active": 2 } }, My JS code: var endpoint = 'api/location' async function getLocalization() { try { const response = await fetch(endpoint); return await response.json(); } catch (error) { console.log(error); } } async function renderLocalization() { let address = await getLocalization(); return address }; function initMap() { // The location of Uluru const uluru = { lat: -25.344, lng: 131.031 }; // The map, centered at Uluru const map = new google.maps.Map(document.getElementById("map"), … -
Getting a Bad Request when making a POST request in djangorestframework
I'm getting the following error when I try to make a POST request to the server; "detail": "JSON parse error - Expecting value: line 1 column 1 (char 0)" The request is successful when I POST null content or input in a dictionary, i.e {"content": "Hello world"}.
