How to update multiple objects at once in Django?
As the image presents I have to update multiple objects at once, e.g. to update the status of each object. If the status is active, the object will display on another page and vice versa. The goal is to change the status of one object (or all) with one button. At the moment if I click on 'Update_all' I got only one value. Django's Admin Page to take action on multiple objects would be a nice solution, but I have no idea, how this template is constructed although I considered the html code of the template. Another try I attempted - similiar to the image above - was this one: My template <div class="container"> {% if forms.items %} {% for key,value in forms.items %} <form class="custom-form-manage-habis" method="post" action=""> {% csrf_token %} <div class="container custom-div-manage-habits"> {{key}} &emsp; {{value}} </div> <hr> {% endfor %} {% else %} <p>There are no habits to manage.</p> {% endif %} <input type="submit" value="Apply changes" {% if not forms.items %}style="display:none"{% endif %} ></input> </form> </div> ...and in my view: def post(self, request): print('postFuction') print(request.POST) form_collection = {} habit_update_list = request.POST.getlist('is_active') print(habit_update_list) habits = Habit.objects.filter(created_by=request.user.userprofile) i = 0 for habit in habits: print('I: ' + str(i)) form = … -
Regex validator does not work with Django admin forms
I try to use a RegexValidator with a CharField, but I can't make it work... class Configuration(models.Model): name = models.CharField(verbose_name=u'Name', validators = [RegexValidator(regex="[a-z]", message="Not cool", code="nomatch")]) I then just register it with admin.site.register(Configuration) But then in the admin forms, it accepts any possible name...

How to submit two ModelMultipleChoiceFields inputs as one ManyToMany field in Django Admin?
Here is my model: class Gym(TranslatableModel, BaseActive): ... tag_list = models.ManyToManyField(Tag) @property def services(self): return self.tag_list.filter(category=TagCategory.GYM_SERVICE) @property def activities(self): return self.tag_list.filter(category=TagCategory.GYM_ACTIVITY) And here is how the GymAdmin renders: First I needed to divide the "Tag List" multiple select input in the admin into two separate multiple select fields, namely "Services" and "Activities". So I did this: class GymForm(forms.ModelForm): class Meta: model = Gym fields = '__all__' exclude = ['tag_list',] services = forms.ModelMultipleChoiceField( widget=forms.CheckboxSelectMultiple, queryset=Tag.objects.filter(category=TagCategory.GYM_SERVICE), required=False ) activities = forms.ModelMultipleChoiceField( widget=forms.CheckboxSelectMultiple, queryset=Tag.objects.filter(category=TagCategory.GYM_ACTIVITY), required=False ) @admin.register(Gym) class GymAdmin(TranslatableAdmin): inlines = [...] form = GymForm Which gets rendered by the admin like this: Now I need to take all "Activities" and "Services" selected, clean their values by joining them together, and submit them as the single "tag_list" ManyToMany field in my model. How can I do this? Thank you for your time! -
Adding images created from Pillow to a single Django object
I have an wrote a small app that takes a single .gif as an upload and it splits the gif into frames using Pillow. I'm saving the .gif through a Document model and the frames through DocumentImage model. Currently, the app saves the .gif object and creates one object for each frame. What I want is all the frames be saved into a single object and that object be linked to the gif object. Here's what I have so far: views.py def create_gif(uploadedFile): # create a folder if it doesn't exist try: gif = Image.open('media/' + uploadedFile) print() except: print('Not OK') frames = [frame.copy() for frame in ImageSequence.Iterator(gif)] i = 0 while (i < len(frames)): buffer = BytesIO() frames[i].convert('RGB').save(fp=buffer, format='JPEG') finalImage = InMemoryUploadedFile(buffer, None, os.path.basename(uploadedFile)[:-4] + str(i) + '.png', 'image/jpeg', frames[i].tell, None) imageToSave = DocumentImage(imagefile=finalImage) imageToSave.save() i += 1 def list(request): # Handle file upload if request.method == 'POST': form = DocumentForm(request.POST, request.FILES) if form.is_valid(): newdoc = Document(docfile=request.FILES['docfile']) if os.path.splitext(newdoc.docfile.name)[1].lower() != '.gif': messages.add_message(request, messages.INFO, "Please select a gif") else: newdoc.save() uploadedFile = newdoc.docfile.name create_gif(uploadedFile) messages.add_message(request, messages.INFO, "Saved") return HttpResponseRedirect(reverse('list')) else: form = DocumentForm() # A empty, unbound form # Load documents for the list page documents = Document.objects.all() # Render … -
Connecting to a RADIUS Server using pyrad
In order to get my Django Backend Auth up and running, I've developed a small script that should connect to a radius SERVER: RADIUS_SERVER = 'abcs013p' RADIUS_SECRET = b'secret' RADIUS_DICTIONARY = "dictionary.txt" class RADIUS_Auth: def __init__(self, login, password): self.radius_authentication(login, password) def radius_authentication(self, login, password): client = Client(server=RADIUS_SERVER, secret=RADIUS_SECRET, dict=Dictionary(RADIUS_DICTIONARY)) # create request req = client.CreateAuthPacket(code=pyrad.packet.AccessRequest, User_Name=login) #NAS_Identifier="localhost"?? req["User-Password"] = req.PwCrypt(password) # send request reply = client.SendPacket(req) if reply.code == pyrad.packet.AccessAccept: print("access accepted") else: print("access denied") if __name__ == '__main__': RADIUS_Auth('PYMAT', 'London123') In my dictionary.txt I just have some simple text: letmein The first issue is, what details should I put for the NAS_Identifier, if any. Secondly, I receive a KeyError: 'User-Name' that gets thrown out when I try to create a request (the "req = " line). Can my script be improved somehow to at least get connectivity? -

OneToOneField to abstract model
I'm looking to create a database structure where each Group has a link to a single Policy. A Policy can be one of a variety of different types, each of which:- may have extra attributes will definitely have a method called do_this() and one called do_that() Over time, more Policys will be created, each with their own attributes etc. My initial instinct with this was to go with Policy being an abstract class with a link back to the Group and stubs for the methods:- class Policy(models.Model): group = models.OneToOneField(Group) class Meta: abstract = True def do_this(): raise NotImplementedError() def do_that(): raise NotImplementedError() Then different policy types can add their own attributes but they have to implement the interface. class PolicyA(Policy): new_attribute = models.IntegerField() def do_this(): # implementation A def do_that(): # implementation A But if I do that, then I have no way of asking a Group for it's Policy, as Policy is abstract. If I remove the abstract setting, then (using something like django model utils, I guess) I can get the "real" type of the Policy at runtime but that doesn't feel right to me. I've read up a bit on generic relations but is that the … -

connecteing android app to django web server's postgresql on heroku
I have deployed a web server on heroku based on django framework and connected to heroku's postgresql. Now I am building an android application that authenticates data from server for instance there is a login form. On searching I have found that making a HTTP request by android can work but it is a bit unclear to me still. I have following queries in mind. I am using auth users in my web app and built in login functionality so do I have to create a separate django view that accepts HTTP request and respond accordingly? If yes how do I authenticate? The android should make a post request? passing username and password? I am new in android so don't know much about it. Kindly guide me what should I do. -
