File Upload Feature Documentation
Overview
The File Upload feature allows users to upload images or other files and associate them with specific entities in the application. This feature is implemented using Django's file handling capabilities.
Key Components:
Models:
Define models to represent entities that can have associated files. Models include fields for storing file uploads.
Code:
from django.db import models
class Document(models.Model):
description = models.CharField(max_length=255, blank=True)
document = models.FileField(upload_to='documents/')
uploaded_at = models.DateTimeField(auto_now_add=True)
def __str__(self):
return self.description if self.description else str(self.id)
Forms:
Create forms to handle file uploads associated with entities.
Code:
from django import forms
from .models import Document
class DocumentForm(forms.ModelForm):
class Meta:
model = Document
fields = ('description', 'document')
Views:
Implement views to handle file uploads and save files to the database.
from django.shortcuts import render, redirect
from .forms import DocumentForm
def upload_document(request):
if request.method == 'POST':
form = DocumentForm(request.POST, request.FILES)
if form.is_valid():
form.save() # This will save the uploaded document to the database
return redirect('upload_document') # Redirect to admin page or any other page as needed
else:
form = DocumentForm()
return render(request, 'upload_document.html', {'form': form})
def upload_success(request):
return render(request, 'upload_success.html')
Templates:
Develop HTML templates to render file upload forms.
