How do I solve a None error in a translation website
I am currently coding my first website, which is a translator in an invented language. You input a random phrase and it should get translated in the invented language. Here's the code for the translation: class TranslatorView(View): template_name= 'main/translated.html' def get (self, request, phrase, *args, **kwargs): translation = "" for letter in phrase: if letter.lower() in "a": if letter.isupper(): translation = translation + "U" else: translation = translation + "u" elif letter.lower() in "t": if letter.isupper(): translation = translation + "A" else: translation = translation + "a" elif letter.lower() in "c": if letter.isupper(): translation = translation + "G" else: translation = translation + "g" elif letter.lower() in "g": if letter.isupper(): translation = translation + "C" else: translation = translation + "c" return render(request, 'main/translator.html', {'translation': translation}) def post (self, request, *args, **kwargs): self.phrase = request.POST.get('letter') translation = self.phrase context = { 'translation': translation } return render(request,self.template_name, context ) Template where you input the phrase: {% extends "base.html"%} {% block content%} <form action="{% url 'translated' %}" method="post">{% csrf_token %} <div class="form-group"> <center><h2 class = "display-3">TRANSLATE YOUR DNA CHAIN</h2></center> <br> <br> <textarea class="form-control" name='text' id="exampleFormControlTextarea1" rows="6"></textarea> <br> <button type='Submit' class= "btn btn-primary btn-lg btn-block">Translate</button> </div> </form> {% endblock content %} Template where … -

User filtering in Django, how to return specific user's data?
Been trying to figure this out for a long time(as in days), but can't understand what to use to return one users "events". A bit new and unfamiliar so would love any help I could get.

Django Translation (Translate Database Values)
I'm working on a project and they asked me to make the project multilingual. but they don't have specific languages, and I want to handle this in the simplest and smarter way so I thought if I use django-modeltranslation package it will be good for me. things to know: 1- there are a lot of fields that need to translate into a lot of models and columns. 2- I Im working on drf, the front end in another language. things to do : 1- I want to make dynamic serializers to handle the columns that contain translation. ex(name_en, name_fr, name_ar ...etc.) so the serializer should return the "name" key always, not "name_en" or "name_fr". I made some code and worked fine with me but it will be a headache for me and hard to cover all cases and fields that I need to translate. example code : models.py name = models.CharField(max_length=250, blank=True, null=True) translation.py from modeltranslation.translator import translator, TranslationOptions from .models import Category class CategoryTranslationOptions(TranslationOptions): fields = ('name', 'description') translator.register(Category, CategoryTranslationOptions) request_helper.py def check_language(language): if language: return language else: return "en" def check_accept_language_header(headers): is_lang = False if "Accept-Language" in headers.keys(): is_lang = True if is_lang: return check_language(headers["Accept_Language"]) else: return "en" … -
unique=True always raises exception when used with save(commit=False)
I have a model with two fields f1 and f2. f1 has a unique constraint. I have 2 ModelForms, MF1 and MF2, one for each field. In my view, I render & process the two ModelForms. is_valid() calls on both my_MF1 and my_MF2 are fine. When I save my_MF1.save(commit=False) my_MF2.save() I get a "UNIQUE constraint failed" exception on the second save call. The second call considers that the first one has already created a record with some f1 value. When I save my_MF2.save(commit=False) my_MF1.save() everything works fine. Is this the expected behavior or is this a bug? If it is not a bug, it would be impossible to have both f1 and f2 unique. I am using SQLite. -

How to Django reverse to pages created in Wagtail?
I have a Wagtail model for an object. class ObjectPage(Page): # fields, not really important I want to make the object editable by front-end users, so I have also created a generic update view to accomplish this. My question is how I can use Django's reverse() function to point to the edited object in my get_success_url() method: class EditObjectPage(LoginRequiredMixin, UpdateView): # model, template_name, and fields defined; not really important def get_success_url(self): return("ObjectPage", kwargs={"slug" : self.object.slug}) # doesn't work return("object_page_slug", kwargs={"slug" : self.object.slug}) # also doesn't work I know how to do this when I'm explicitly defining the URL name in my urls.py file, but in this case, the URL is created as a Wagtail page and is handled by this line of my urls.py: url(r"", include(wagtail_urls)), I've been searching the documentation for whether Wagtail pages are assigned names that can be reversed to, but I'm finding nothing in the official documentation or here on StackOverflow. -

Apply DRY to a dict where data is coming from different vars
I have two functions where I pass the dict event_data = {[...]} to the Google API. The only difference is that for update_calendar_event the data is coming from a dict. For create_calendar_event it is an obj. Do you have any idea how to apply DRY here while considering that it's these two different types? class GoogleCalendarAPI: def __init__(self) -> None: # cache_discovery=False to avoid ImportError self.service = build( "calendar", "v3", credentials=credentials, cache_discovery=False ) def _event_link(self, event_slug: str) -> str: return "https://example.com/events/" + event_slug def update_calendar_event( self, calendar_event_id: str, validated_data: Dict[str, Any], event_slug: str ) -> None: event_data = { "summary": validated_data.get("name"), "description": validated_data.get("description") + "\n\nEvent link: " + self._event_link(event_slug), "start": { "dateTime": validated_data.get("start_date").isoformat(), "timeZone": validated_data.get("timezone"), }, "end": { "dateTime": validated_data.get("end_date").isoformat(), "timeZone": validated_data.get("timezone"), }, } self.service.events().patch( calendarId=CALENDAR_ID, eventId=calendar_event_id, body=event_data ).execute() def create_calendar_event(self, event_instance) -> str: event_data = { "summary": event_instance.name, "description": event_instance.description + "\n\nEvent link: " + self._event_link(event_instance.slug), "start": { "dateTime": event_instance.start_date.isoformat(), "timeZone": event_instance.timezone, }, "end": { "dateTime": event_instance.end_date.isoformat(), "timeZone": event_instance.timezone, }, } event = ( self.service.events() .insert(calendarId=CALENDAR_ID, body=event_data) .execute() ) return event.get("id") -
Override label offset in Fieldset for Crispy Forms
I have a Fieldset in my layout, which contains a checkbox on the first line. For the main form I've set: self.helper.layout_class = "create-label col-md-2" which aligns my labels and fields and creates an "even" form. The problem is, this gets applied within a fieldset and a checkbox gets shuffled to the right, description on the right, and it looks like it's just hanging in the middle of the screen: This is because the generated html is applying the offset generated for labels, and ends up looking like this: <div class="form-group row"> <div class="offset-md-2 col-md-10"> <div id="div_id_allow_invitees_to_add_others" class="custom-control custom-checkbox"> <input type="checkbox" name="allow_invitees_to_add_others" class="checkboxinput custom-control-input" id="id_allow_invitees_to_add_others"> <label for="id_allow_invitees_to_add_others" class="custom-control-label"> Allow invitees to add others </label> If I manually remove the offset-md-2 in the browser inspector, it displays exactly as I want - over on the left ... I just moved the Fieldset to it's own Div in the hope I could override this, but no joy. That bit of the layout is fairly simple: Div( Fieldset( _("Invitees"), Field("allow_invitees_to_add_others"), Formset("invitees"), ), css_class="", ), Can anybody advise me on how to get this checkbox over on the left! -

How do I implement five star rating in Django DetailView?
I'm currently working on a restaurant review site and I'm struggling with displaying a five star rating comment form in a class based DetailView page. How do I implement a five star rating system for my class based RestarurantDetail page? I would like to change the appearence on my Integerfield "rate" to a five star rating field. I would still like to display all other fields in the comment form as normal, perhaps with crispy forms (but it's perhaps not possible if I want to customize the rate field?) If you need aditional information, just let me know! Code Restaurant Model (parts of it) in Models.py class Restaurant(models.Model): name = models.CharField(max_length = 100) country = models.CharField(max_length = 75) city = models.CharField(max_length = 75) address = models.CharField(max_length = 100) categori = models.ManyToManyField(Kategori) description = models.CharField(max_length = 300, blank=True) approved = models.BooleanField(default=False) geom = PointField(null=True) owner = models.ForeignKey(User, on_delete=models.CASCADE) def __str__(self): return self.name class Meta: unique_together = ('country', 'city', 'adress') Comment Model in Models.py class Comment(models.Model): ALTERNATIVES_1 = ( ('Alt 1', 'Alt 1'), ('Alt 2', 'Alt 2'), ('Alt 3', 'Alt 3'), ) restaurant = models.ForeignKey(Restaurant, on_delete = models.CASCADE, related_name='comments') user = models.ForeignKey(User, on_delete = models.CASCADE) title = models.CharField(max_length = 50, blank = … -
Django static folder with css and javascript wont load
Hey I have a problem with the static files directory in Django, Inside the html template I already used the {% load static %} above the link tag and in the link tag I used href="{% static 'style.css' %}" (keep in mind the style.css is in the static folder which is located in the projects root folder (after several times "still not working" I even created the same static folder with the same css file in the respective app folder... and still not working). In the settings.py I used all of the following lines one at a time and even all together STATIC_URL = '/static/' STATIC_ROOT = os.path.join(BASE_DIR, "/static") STATIC_DIRS = ( '/static', ) the html renders perfectly fine and is showing in the browser without any errors but for whatever reason the styling just wont apply (internal and inline sytling works, but I want to use external css). There seems to be a problem in the settings.py file but since I gave the path to the static folder in any way possible, I really don't know what to do. I didnt try with .js files yet but it'll be the same problem I guess. I'm thankfull for any answer.
