question mark breaks regex function in different ways
I have a function that finds substring which start with "@" (usernames), checks database for the username and transforms the substring to a html tag. But for some reason if there is a question mark in the string the first substring before questionmark doesn't get converted. Say the string is: the function above finds all the substrings which start with "@" sign and it works fine: user= re.findall(r"[@]([^¿#@$\\|]*)(?=[¿#@$\\|]|$)", string) user= list(set(user)) and the one above gets first 26 characters (max username len) of every substring and checks the database for usernames. for i in user: k = i[0:26] j = k.rstrip() while True: try: username= User.objects.get(username = j) rest = i.replace(j,"",1) url=url_text(j) string = re.sub(r"[@]({})(?=[¿#@$?\\|]|$)".format(i,),"¿<a class='user-link3' href='/user/{}--{}'>{}</a>{}".format(url,user.id,j,rest),string) break except: if " " not in j: break else: j = j.rsplit(" ",1)[0] j= j.rstrip() So far the function only breaks when there is a "?" in the string and I couldn't figure out why, as it behaves different depending on situation (also I'm not good in regex). Say the string is: string = "@mattarello xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx:https://m.youtube.com/watch?v=zIV4poUZAQo" the function returns: @mattarello xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx:https://m.youtube.com/watch?v=zIV4poUZAQo input 2: "@mattarello xxxxxxxxxxxx?" output 2 "?" gets doubled: "¿<a class='user-link3' href='/user/mattarello--2'>mattarello</a> xxxxxxxxxxxx??" input 3: "@mattarello ????" no output at all. -
How Can I Raise Validation Errors In The Same Way As 'Required' Errors?
I have three types of error messages being displayed. One is the Django error message when a user doesn't fill out a required field. Another is crispy error messages. The last is my own validation errors that are printed using Django messages. I know I can also loop through {% for error in field.errors %} and print them out. Having three different types of error messages doesn't offer a particularly pleasing user experience. I'd like to use just one, either the Django 'required' type errors or crispy errors are the nicest as they appear on the related field. Let's say I go with the Django 'required' type errors, how can I make my validation errors which are raised in my clean method be raised in the same way as required error messages? Thank you. -

I get error when I try to get the list of articles
I am currently working on making the blog site by myself using Python Django. However, I get an error when I run it locally. To write the detail, whenever I try to access (http://127.0.0.1:8000/blog/lp/), the computer says "maximum recursion depth exceeded while calling a Python object" .

get_context_data variable doesn't show up at HTML file
I have just started with using Django with a Django Crash Course book and got stuck on a part. Let me show you what I have done so far and where I got stuck. I opened a templates folder on the hellodjango project folder and wrote some basic HTML code like this. <h1>Greetings</h1> <p>Hello, world!</p> <p>{{my_statement}}</p> Here, the book says that it is okay to write my_statement like this because it will be later understood in python. Later on it tells you to change views.py file under the homepage folder like this. from django.views.generic import TemplateView class HomepageView(TemplateView): template_name = 'index.html' def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) context['my_statement'] = "Nice to see you:" return context However, when I refresh the page my_statement variable doesn't show up on the webpage at all. What could I possibly be doing wrong? I think if I didn't didn't have the packages, an error would pop up? But errors don't show up as well. I have also checked the django documentation on this topic but the code here has similarities to the one I am working with. Thanks for your help. -
How can I create a Django model for a form in which users can choose to add more fields?
I am new to Django and trying to build a resume site. I am using Django WizardForms for users to build out their resume in stages. In the education form, users can add up to 5 different schools they went to. (By using +Add Fields button I implemented with JavaScript) Is this the correct way to write out all the fields in models.py and forms.py? I am sure there must be a cleaner way to do this rather than individually listing out all fields and differentiating them with a number at the end. I have looked into Django FormSets but I am not sure how I would use that with Django WizardForms. Thank you models.py class Profile(models.Model): education_school = models.CharField(max_length=500, null=True, blank=True) education_degree = models.CharField(max_length=500, null=True, blank=True) education_field = models.CharField(max_length=100, null=True, blank=True) education_start = models.CharField(max_length=100, null=True, blank=True) education_end = models.CharField(max_length=100, null=True, blank=True) education_grade = models.TextField(null=True, blank=True) education_description = models.TextField(null=True, blank=True) education_school2 = models.CharField(max_length=500, null=True, blank=True) education_degree2 = models.CharField(max_length=500, null=True, blank=True) education_field2 = models.CharField(max_length=100, null=True, blank=True) education_start2 = models.CharField(max_length=100, null=True, blank=True) education_end2 = models.CharField(max_length=100, null=True, blank=True) education_grade2 = models.TextField(null=True, blank=True) education_description2 = models.TextField(null=True, blank=True) education_school3 = models.CharField(max_length=500, null=True, blank=True) education_degree3 = models.CharField(max_length=500, null=True, blank=True) education_field3 = models.CharField(max_length=100, null=True, blank=True) education_start3 = … -
Is there a way to find the width of the page using jinja2

Django check producing different results in different... Linux distros? (fields.E004)
Host Machine (Ubuntu 20.04, python 3.7.6, fresh virtualenv) I have a PostgreSQL database with a table having a column that has type character-varying. Then I run python manage.py inspectdb. It produces a model like this, which I save as a model file and use in the project: class TestModel(models.Model): message = models.CharField(max_length=-1, blank=True, null=True) (This is expected since Django does not support char fields with no max_length.) Then I run python manage.py check on the host machine, no errors. System check identified no issues (0 silenced). Finally, I run pip freeze > requirements.txt for later use. Docker Container (Base image: python 3.7.6:alpine) The docker image is created using the following Dockerfile: FROM python:3.7.6-alpine WORKDIR /usr/src/app RUN apk update \ && apk add postgresql-dev gcc python3-dev musl-dev RUN pip install --upgrade pip COPY /my_app/requirements.txt . RUN pip install -r requirements.txt COPY /my_app . Then run /bin/sh with the docker image and try: python manage.py check ...It produces an error: myapp.TestModel.message: (fields.E121) 'max_length' must be a positive integer.

DRF Update method for images
I have a Django Post model contains images, text, date of creation and owner who can add other users to view it. I want to add a feature which allows user who is in the shared_to Field to add an image only once. Therefore, I have created ManyToMany Field in order to check if user has already added his image or not. If not, allow him to add an image along with his id so that he won't be able to do that again. I've tried some things in order to add users to ManyToMany field automatically, and check if they are already in it but won't work. model.py class Post(models.Model): post_name = models.CharField(max_length=255) post_text = models.TextField(max_length=360, blank=True) owner = models.ForeignKey( settings.AUTH_USER_MODEL, related_name='owner_user', on_delete=models.SET(get_deleted_user), default=1) created_on = models.DateTimeField(default=timezone.now) date_to_open = models.DateTimeField(blank=False) shared_to = models.ManyToManyField(UserProfile, blank=True, related_name='shared_to_user', null=True,) image_editor = models.ManyToManyField(UserProfile, blank=True, related_name='image_editor_user', null=True) def __str__(self): return self.capsule_name def save(self, *args, **kwargs): super(Capsule, self).save(*args, **kwargs) class PostImage(models.Model): post_file = models.FileField(blank=True, null=True, upload_to='media/covers/%Y/%m/%D/') gallery_post = models.ForeignKey(Capsule, related_name='images', on_delete=models.CASCADE) -
How should I set up the Django model for a complex blog application?
I am attempting to use Django to create a blogging website where I intend to host custom data visualisations created using d3.js. The data which drives the visualisations will then be a mixture of either stored on the server or accessed via APIs from other websites. I am wondering how this would be best implemented in the Django framework? Specifically: Should I store the custom JS as a field within the model? (It feels fundamentally wrong to store code in a text type field in a databse but this seems to be what would follow the model-view-template paradigm) How do I deal with each blog post potentially requiring different backend implementations to access data? -
