[python][django]Uploading files in Django
I have a form.py including Floatfield and Charfield. Now I want to add a new Filefield to upload a text file. But I fail. The float var is submitted successfully and I could see they are changed with the change of the input, but I cannot find the file in located folders. And also, how could I check whether file extensions are correct? Shoudl I achieve it in view or model? Could someone help me? I truly struggled with it. model.py file = models.FileField(upload_to='/Folder', null = True) form.py file = forms.FileField(label='data', required=False) view.py is followed the structure in Django official document. def handle_uploaded_file(f): with open('./test_temp_file.txt', 'wb+') as destination: for chunk in f.chunks(): destination.write(chunk) def file_upload(request): if request.method=='POST': form = input_form(request.POST,request.FILES) if form.is_valid(): handle_uploaded_file(request.FILES['file']) name = request.FILES['filename'].name time = cleaned_data(timezone.now()) form = { 'name' : name, 'time' : time } return render(request, 'home/results.html',{'form':form}) else: form = input_form() return render(request, 'home/input.html', {'form': form}) Thanks. -
How to send value from HTML form into a general context of Django Project
I need to send a value from a html file into a Django View. I need to get user.id_aadgroup.idcustomer.uuid from permissions.html (which is linked to the view PermissionsListView) passed into the context of a brand new view, ApplicationListView() which has the url name applications when I click on the submit button. Here is the code: permissions.html in the django app permissions <form action="{% url 'applications' user.id_aadgroup.idcustomer.uuid %}" method="get"> <button type="submit" class="btn btn-outline-primary" value="go to manage permissions">Accéder au contrat</button> </form> view.html in the django app applications class ApplicationListView(ListView): model = ViewDevpermissionapplicationuser template_name = 'applications/applications.html' def get_context_data(self, **kwargs): kwargs.update( user= self.request.session.get('user', {'is_authenticated' : False}) ) context = super().get_context_data(**kwargs) return super().get_context_data(**kwargs) Think I can do it with a form but don't know how, any suggestions ? -

Django: combine ListView and DeleteView to use with HTMX?
I’m using Django with HTMX to manage a CRUD table in which I want to list and delete objects. For this, I have a ListView which displays a table (using django-tables) with pagination, sorting, and text search features. It works as expected with HTMX: for example, if you go to the next page, the whole page is not reloaded: HTMX gets the table and upload a specific part of the DOM. It looks like this: The code of the ListView looks like: class Proposals(SingleTableMixin, SearchableMixin, ListView): table_class = ProposalTable # for django-tables2 ordering = "id" model = Proposal paginate_by = 5 search_filters = ["title__icontains"] # custom text search def get_template_names(self): # Trick to chose between loading the whole page (first time user goes to the page) or just the table via HTMX (when user uses pagination or sorting, it reloads the table only in the DOM) if self.request.htmx: return "fragments/proposals_fragment.html" return "proposals.html" Now, I’m trying to add a delete feature, with the best UX. I have explored multiple ways until now: Just by removing the row from the DOM once the object is actually removed from the DB → bad: while it’s fast, it makes the pagination wrong/inconsistent, and with … -
Django - Easiest way to translate just 1 page
I want to translate only 1 page (1 Django template) to 2 different languages. After reading a bit about Django internationalization, seems quite complex and probably an overkill for my use case (it's just 1 page and not even a public website, just an internal report). It would be great if I could use the same view for different 2 templates (one template for each language), but I don't know how to do that. Currently, I'm using something like this to send the info to the template (the list is actually much longer): context = { 'campaigns' : campaigns, 'data_campaigns' : data_campaigns, 'manual_changes' : manual_changes, 'groups_bad' : groups_bad, } return render(request, 'english.html', context) It would be great if I could create a "spanish.html" template and just translate the text directly in that template. Is it possible? Are there better (and not very complex) solutions? Also, maybe using "context" like this is not a best practice. I'm learning Django, it was the easiest option I found and it works. I'm open to change it. Thanks! -

Looking for the right Tools for developing a website with SPA components in Django
i am a new Webdeveloper and im struggeling to find the right tools and frameworks to use for the specific site i am building. Its a site for managing all kind of information and documents about clients my firm cares for. It consists of general information (like statistics etc.) that should be served synchronously and a client specific part that should be a SPA (mainly because i want to have a list of all clients on the side, so that the main part of the page updates when you click one). My problem is , that there is so much information about that kind of stuff (but not specificly a project comparable to mine), so that i can't decide what the best approach would be. I found those options so far: Just serve everything with django and update reactive parts of the page with Ajax building a dedicated Frontend and with Frameworks like Svelte or React and using Django as API. Using these Frameworks just for the critical components that have to be reactive and serving everything with django If i understand correctly, the cleanest way would be Nr. 2, but i would lose access to djangos form rendering with … -

Django getting NoneType error when querying tags using TaggableManager
I am creating a blog with Django and using TaggableManager to fetch similar posts. I get int() argument must be a string, a bytes-like object or a number, not 'NoneType' when I request a post (PostDetail view) which has only one tag that has not been used in other posts. If the post has a tag which was used before or two tags, one new and one used before, all is fine. The issue might be because I'm querying a reverse foreign key, so 'None' appears for tags not having any post (source Django documentation on values_list) models.py class Post(models.Model): tags = TaggableManager( help_text="We suggest to use no more than 3 tags to improve search results") views.py class PostDetail(View): def get(self, request, slug, *args, **kwargs): # fetch post by similarity post_tags_ids = post.tags.values_list('id', flat=False) similar_posts = Post.objects.filter(tags__in=post_tags_ids)\ .exclude(id=post.id) similar_posts = similar_posts.annotate(same_tags=Count('tags'))\ .order_by('-same_tags') I'm following the example shown in the book Django by Example here's the repository. I'd like my detailed view of the post to be shown anyways, how can I avoid getting 'NoneType'? Thanks in advance for any help. -

Pass Django's "to_field" argumento in model, two fields that have a UniqueConstraint
What I'm trying to accomplish is to have the "dependencia" field on Puesto model as Charfield, in order to use the natural keys and pass for example this "[NTRA. SRA.

Because the "descripcion" and "departamento" fields in "Dependencia" can't have the argument unique= True, I can't use them to point to those fields and finally get "dependencia" on Puesto model converted from int (because is pointing to the id field in dependencia which is the PK), to Charfield.

Django - CreateView form_valid() how can I access foreign key objects
I think I complicate this more because what I am using for the Foreign Key has a Choice setting and I have the Foreign Key set to show the human readable choice.

I am using the following ModelForm: class ListingQuoteForm(forms.ModelForm): author_phone = forms.CharField(validators=[validate_phone_number]) content = forms.CharField( label='Your message', min_length=50, widget=forms.Textarea(attrs={'rows': 4}), help_text='Please provide a few details about your race and your requirements', ) def __init__(self, *args, **kwargs): user = kwargs.pop('user', None) super().__init__(*args, **kwargs) if user.is_authenticated: self.fields['author_name'].initial = user.full_name(strict=True) self.fields['author_email'].initial = user.email self.fields['author_email'].disabled = True class Meta: model = QuoteRequest fields = ('author_name', 'author_email', 'author_phone', 'content') labels = { 'author_name': 'Your name', 'author_email': 'Your email', 'author_phone': 'Your phone number', } and rendering it in the following template: {% load crispy_forms_tags %} <div class="listing-section" id="quote-form"> <div class="listing-section-header"> {% if primary_category.quote_request_type == 'quote' %} <h2>Request a quote</h2> {% elif primary_category.quote_request_type == 'info' %} <h2>Request more info</h2> {% endif %} </div> <div class="listing-section-body"> <form method="POST" enctype="multipart/form-data"> {% csrf_token %} {{ quote_form.author_name|as_crispy_field }} {{ quote_form.author_email|as_crispy_field }} {{ quote_form.author_phone|as_crispy_field }} {{ quote_form.content|as_crispy_field }} <div class="form-group"> <button class="standard-button standard-button--submit" type="submit">Send</button> </div> </form> </div> </div> When the content field min length validation fails, a message is displayed like so: But when my custom phone number validation fails, the error displays under the field like so: How can I get my phone number validation error to display the same way the in-built min length validation does for the CharField?
