Django adding colon to the path out of nowhere
I have a pretty simple Django project based on the one from the tutorial that I am slowly morphing into my own app. It was working fine locally. I tried to deploy it to Heroku, so I made a few changes, but it was still working fine locally (I am still working on getting it to work on Heroku). But then I ran it once more and out of nowhere I am getting this error: Invalid argument: 'C:\\Users\\cusack\\PycharmProjects\\pythonProject\\website\\:\\index.html' So it is adding :\\ or \\: to the path for some reason. I have looked at settings.py, views.py, urls.py, and I can't find anywhere where I have told it to do this. My urls.py file looks (partially) like this: urlpatterns = [ path('', views.index, name='index'), path('images/random.png',views.my_image,name='randomImage'), path('admin/', admin.site.urls) ] The main page and admin both give this error, but 'images/random.png' works just fine. For the admin page, it is adding the extra :\\ before admin\\index.html. My views.py for this index is trivial: def index(request): return render(request, 'index.html') It happened when I was playing around with DEBUG and ALLOWED_HISTS, although changing them back to True and [] didn't seem to help. Any idea where this could be coming from? -
Because a cookie’s SameSite attribute was not set or is invalid, it defaults to SameSite=Lax
I've been working on a Django project, I'm using Pycharm community edition 2021 and Django version as 4.0.3, the problem is that , whenever I reload my site there would be no pictures shown which I want to display from another website. Error would be like "Indicate whether to send a cookie in a cross-site request by specifying its Same Site attribute", I have tried much more method to resolve this adding removing cookies but unable to solve it, as I dnt know whether these same site cookies would be in IDE , Django or chrome? {% extends 'base.html'%} {% block body %} <div class="container my-4 mx-4 py-8 px-8" > <div id="carouselExampleControls" class="carousel slide" data-bs-ride="carousel"> <div class="carousel-inner"> <div class="carousel-item active"> <img src="https://api.unsplash.com/search/photos?&client_id=wIXk0jpTFTYBNuisfNDCRmfWDt- ZDTXZhBtviWWN7U8&query=office" class="d-block w-100 " alt="..."> </div> <div class="carousel-item"> <img src="https://api.unsplash.com/search/photos?client_id=wIXk0jpTFTYBNuisfNDCRmfWDt- ZDTXZhBtviWWN7U8&query=office" class="d-block w-100" alt="..."> </div> <div class="carousel-item"> <img src="https://api.unsplash.com/search/photos?client_id=wIXk0jpTFTYBNuisfNDCRmfWDt- ZDTXZhBtviWWN7U8&query=office" class="d-block w-100" alt="..."> </div> </div> <button class="carousel-control-prev" type="button" data-bs- target="#carouselExampleControls" data-bs-slide="prev"> <span class="carousel-control-prev-icon" aria-hidden="true"></span> <span class="visually-hidden">Previous</span> </button> <button class="carousel-control-next" type="button" data-bs- target="#carouselExampleControls" data-bs-slide="next"> <span class="carousel-control-next-icon" aria-hidden="true"></span> <span class="visually-hidden">Next</span> </button> </div> </div> {% endblock body %} -
how to place the images in the select of my template to make the language change?
it is very very basic but my inexperience does not make me see the error. Well, the flags don't appear, but it is the folder and also the path, because I have other images that have the same path, only instead of flags it says brands <select class="selectpicker" data-width="fit"> <option><img src="{%static 'assets/images/flags/spain.jpg' %}" alt="">English</option> <option><img src="{%static 'assets/images/flags/us.jpg' %}" alt="">Español</option> </select> -
Python Django "surrogates not allowed" error on model.save() call when text includes emoji character
We are currently in the process of building a system that stores text in a PostgreSQL DB via Django. The data gets then extracted via PGSync to ElasticSearch. At the moment we have encountered the following issue in a testcase Error Message: UnicodeEncodeError: 'utf-8' codec can't encode characters in position 159-160: surrogates not allowed We identified the character that causes that issue. It is an emoji. The text itself is a mixture of Greek Characters, "English Characters" and as it seems emojis. The greek is not shown as greek, but instead in the \u form. Relevant Text that causes the issue: \u03bc\u03b5 Some English Text \ud83d\ude9b\n#SomeHashTag \ud83d\ude9b\ translates to this emoji:🚛 As it says here: https://python-list.python.narkive.com/aKjK4Jje/encoding-of-surrogate-code-points-to-utf-8 The definition of UTF-8 prohibits encoding character numbers between U+D800 and U+DFFF, which are reserved for use with the UTF-16 encoding form (as surrogate pairs) and do not directly represent characters. PostgreSQL has the following encodings: Default:UTF8 Collate:en_US.utf8 Ctype:en_US.utf8 Is this an utf8 issue? or specific to emoji? Is this a django or postgresql issue? -
django ModuleNotFoundError: No module named 'debug-toolbar'
I just tried to install the django-debug-toolbar. I believe I followed all the steps as indicated in the docs. I am using docker, so I included the following in my settings: if os.environ.get('DEBUG'): import socket hostname, _, ips = socket.gethostbyname_ex(socket.gethostname()) INTERNAL_IPS = [ip[: ip.rfind(".")] + ".1" for ip in ips] + ["127.0.0.1", "10.0.2.2"] After installing, I ran docker-compose build then docker-compose up -d. docker-compose logs and docker-compose exec web python manage.py collectstatic show the error ModuleNotFoundError: No module named 'debug-toolbar' The only thing I think I did differently from the docs is that I use pipenv. I exited docker-compose and then installed via pipenv install django-debug-toolbar. Debug toolbar is in my pipfile. FWIW I'm never sure if I'm supposed to exit docker-compose before install a module via pipenv (or if it matters). -

Formset with request.post not initializing correctly
I am having an issue using formsets and request.POST. Whenever I initialize the formset without request.POST it works as intended, but will not send the data through as the form is never valid. If I include request.POST (as I have done on all my other forms in the view) the formset doesn't seem to initialize correctly. No data gets through, I can't see any form fields, and I get a html warning saying: (Hidden field TOTAL_FORMS) This field is required. (Hidden field INITIAL_FORMS) This field is required. Here is a very simplified version of what I am doing in my project. This is bare minimum and the project itself is much more involved. But this should be the heart of the problem I am having. The intent of this very basic form is that my formset would have 3 forms, each one initialized with a letter, 'a', then 'b', then 'c'. views.py def MyView(request): my_formset = formset_factory(my_form) my_list = ['a', 'b', 'c'] if request.method == 'POST': my_formset = formset(request.POST, initial=[{'field1':x} for x in my_list]) #If I remove 'request.POST' then the form initializes correctly, but will never pass .is_valid() if my_formset.is_valid(): print('valid') else: print('invalid') else: my_formset = formset(initial=[{'field1':x} for x in … -

Does python web frameworks like Flask/Django have a build process?
I have recently started learning CI/CD concepts. In the tutorials, they used a react website to show the build stage. I was wondering do we have a build phase for applications developed using frameworks like Django/flask? For these applications, we generally run a single command to start the application directly from source code like: python manage.py runserver python app.py Also, in general, is to possible (and okay?) for a web application not to have a build phase? Any knowledge here would be helpful. Thanks in advance! -

In Django, how do I add a join table relation to an existing model?
I'm using Python 3.9 and Django 3.2. I have these models. The second is a join table for the first class Coop(models.Model): objects = CoopManager() name = models.CharField(max_length=250, null=False) types = models.ManyToManyField(CoopType, blank=False) addresses = models.ManyToManyField(Address, through='CoopAddressTags') class CoopAddressTags(models.Model): # Retain referencing coop & address, but set "is_public" relation to NULL coop = models.ForeignKey(Coop, on_delete=models.SET_NULL, null=True) address = models.ForeignKey(Address, on_delete=models.SET_NULL, null=True) is_public = models.BooleanField(default=True, null=False) I would like to actually reference the join table in my first model, so I added address_tags = models.ManyToManyField('CoopAddressTags') like so class Coop(models.Model): objects = CoopManager() name = models.CharField(max_length=250, null=False) types = models.ManyToManyField(CoopType, blank=False) address_tags = models.ManyToManyField('CoopAddressTags') addresses = models.ManyToManyField(Address, through='CoopAddressTags') but I'm getting this error when I run a script to generate migraitons $ python manage.py makemigrations directory SystemCheckError: System check identified some issues: ERRORS: directory.Coop.address_tags: (fields.E303) Reverse query name for 'directory.Coop.address_tags' clashes with field name 'directory.CoopAddressTags.coop'. HINT: Rename field 'directory.CoopAddressTags.coop', or add/change a related_name argument to the definition for field 'directory.Coop.address_tags'. I'm not clear what this means or how to resolve it. The goal is that when I have a "Coop" object, I can reference its addresses and whether or not those addresses are public. -

Cannot add extra styles to django-ckeditor
django-ekeditor packages comes with highlight.js library for code snippets and that library comes with some pre-installed styles. As I prefer seti-ui style, I download it from highlightjs.org. Inside the downloaded package is seti-ui.min.css file and I copy it to \venv\Lib\site-packages\ckeditor\static\ckeditor\ckeditor\plugins\codesnippet\lib\highlight\styles where all other styles are and then set this in my settings.py: 'codeSnippet_theme': 'seti-ui' # based on the name of css file And it doesn't work. The editor shows the code snippet but without any style. I've tried several other pre-installed themes like monokai and foundation and they work fine. Then I noticed that seti-ui.min.css is inside a subfolder base16 in the package I downloaded from highlightjs.org, so I tried \venv\Lib\site-packages\ckeditor\static\ckeditor\ckeditor\plugins\codesnippet\lib\highlight\styles\base16 too but didn't work either. So what is the correct method to add it? -
