Using Nibabel in Django
I am making a web app that converts .nii files to png(zip). I have implemented the main logic in python but am facing problems porting it to the web app. So I want to create a form that accepts a .nii file and outputs a zip file containing all the .png slices. So far I've written a simple view: Views.py from django.shortcuts import render from .forms import SharingForms from django.http import HttpResponse import imageio,nibabel,numpy from zipfile import ZipFile from .models import NII def index(request, **kwargs): if request.method == 'POST': form = SharingForms(request.POST,request.FILES) if form.is_valid(): for field in request.FILES.keys(): for formfile in request.FILES.getlist(field): file = NII(file = formfile) file.save() response = HttpResponse(content_type='application/zip') zip_file = ZipFile(response, 'w') image_array = nibabel.load(file).get_fdata() if len(image_array.shape) == 4: # set 4d array dimension values nx, ny, nz, nw = image_array.shape total_volumes = image_array.shape[3] total_slices = image_array.shape[2] for current_volume in range(0, total_volumes): slice_counter = 0 # iterate through slices for current_slice in range(0, total_slices): if (slice_counter % 1) == 0: # rotate or no rotate data = image_array[:, :, current_slice, current_volume] #alternate slices and save as png print('Saving image...') image_name = file[:-4] + "_t" + "{:0>3}".format(str(current_volume+1)) + "_z" + "{:0>3}".format(str(current_slice+1))+ ".png" imageio.imwrite(image_name, data) print('Saved.') zip_file.write(image_name) zip_file.close() response['Content-Disposition'] … -
Django Multi Tenant Schemas Media Files Path
I am using Django with Multi Tenant Schemas. Everything is working well on production, but I am having an issue with image media Path. My web server is an Apache2 installed on Ubuntu 18.04, in the site configuration file I have: ''' ServerName qibot.com.br ServerAlias tenant1.qibot.com.br tenant2.qibot.com.br tenant3.qibot.com.br ServerAdmin webmaster@localhost DocumentRoot /var/www/html Alias /static /var/www/qibot_system/static <Directory /var/www/qibot_system/static> Require all granted </Directory> Alias /media /var/www/qibot_system/media/ <Directory /var/www/qibot_system/media/> Require all granted </Directory> ... </VirtualHost> ''' In this way, if the media (image or video) file is requested, django looks for /var/www/qibot_system/media/ instead of /var/www/qibot_system/media/tenant1 or /var/www/qibot_system/media/tenant2 or /var/www/qibot_system/media/tenant3 My question is, there is a way to set the variable on the end of /var/www/qibot_system/media/XXXXXXXXX to provide right path to django?

Dependent Dropdown form in Admin
I want to build a dependent dropdown form in Admin which has fileds Tag1, Tag2, Tag3, Title and Deadline. It should be such that the user selects some Tag1 and based on it he can select Tag 2. Also Tag3 depends on tag1 choice and the title choice depends on all the above tags in the form. The deadline value is based on the title selected. However if the selected title is "OTHER" he can add add a title manually and also the deadline manually. Here is an approach I tried: Created 4 different models, c1, c2, c3 and task(which saves title and deadline). Error 1: If i use c1's foreign key in c3, it does not run. Error 2: even if i set c3 dependent of C2 I dont get the list of objects in the dropdown for either of them. Error 3: Even after entering the values for new objects, I am unable to make it work. I am working on this since 4 days but I am unable to figure a way out. here's my Code models.py: class c1(models.Model): name = models.CharField(max_length=30, default="Other") def __str__(self): return self.name class c2(models.Model): '''c1_choice=(('Support Staff','Support Staff'), ('Consumables', 'Consumables'))''' c1 = models.ForeignKey(c1, … -

Save relation between anonymous user and a file with user login with foreign key - Django
I am a beginner with programming and trying to make a web app that creates a video programmatically on button click in browser and displays it in the same browser for the user once it's created. I want it to be something like this but the button runs a moviepy script to create the video and upload it to a django model and pass it through a view. Now I am trying to create the relationship between person who clicks the button and the video that is created with foreign key. I want to do this without a login and I see a lot of tutorials about associating a user that is logged in but not so much about anonymous users. Is my approach the right one?

Can we use multiple OneToOneFields in single User Model? Any performance issue happen?
I'm new to django, I'm working on a project. I have define User model with multiple parts. User --> default property like username, email, password, date_joined, is_staff, is_superadmin... UserProfile --> OneToOneField(User), first_name, last_name, gender, avatar, dob. UserPhoneAuth --> OneToOneField(User), otp_code, etc.. UserEmailAuth --> OneToOneField(User), secret_key, etc...
