How to download a file from FileField django

(Django) How to send the same data to some clients instead of others?
I need your help! I have a server running into django with clients connecting to it. Once they are connected some objects "User" are added to the database with some property, such as user_id etc.. I'd like to write a function that send the same data (e.g. a color) back to only some of them to color the body of the html, and other data to others..how can I identify the clients to which the server should send the data? I was thinking to trigger the function with a button that make an ajax call to the server, but then I don't know how to take track of the "identification" of the client in the server. -
Django profile pic upload saves picture in two folders
I've made a group picture upload in Django, but it saves in /media folder and in /media/group_pics folder. Expected behaviour: It only saves to /media/group_pics folder models.py: class Group(models.Model): name = models.CharField(max_length=15, unique=True) date_created = models.DateField(default=timezone.now) image = models.ImageField(default='group_pics/default-group.jpg', upload_to='group_pics/') def __str__(self): return self.name def image_url(self): if self.image and hasattr(self.image, 'url'): return self.image.url def save(self, *args, **kwargs): try: group = Group.objects.get(id=self.id) if not ('default-group.jpg' in group.image.url) and group.image != self.image: group.image.delete() except: pass if not self.slug: self.slug = self._get_unique_slug() super().save(*args, **kwargs) forms.py class GroupUpdateForm(ModelForm): image = forms.ImageField(max_length=150, allow_empty_file=False) x = forms.FloatField(widget=forms.HiddenInput(), required=False) y = forms.FloatField(widget=forms.HiddenInput(), required=False) width = forms.FloatField(widget=forms.HiddenInput(), required=False) height = forms.FloatField(widget=forms.HiddenInput(), required=False) class Meta: model = Group fields = ['image'] def save(self): group = super(GroupUpdateForm, self).save(commit=False) if self.cleaned_data.get('x') != None: x = self.cleaned_data.get('x') y = self.cleaned_data.get('y') w = self.cleaned_data.get('width') h = self.cleaned_data.get('height') image = Image.open(group.image) cropped_image = image.crop((x, y, w+x, h+y)) resized_image = cropped_image.resize((350, 350), Image.ANTIALIAS) resized_image.save(group.image.path) group.save() return group and views.py if request.method == 'POST': update_form = GroupUpdateForm(request.POST, request.FILES, instance=group) if update_form.is_valid(): update_form.save() Where is my mistake that causes the double image save? -
Wagtail rendering if referenced pages in an inlineModel
In my Article pageModel I have an InlinePanel('technologies', label="Technologies"), which loads up an ArticlesPageTechnologies(Orderable) which is using PageChooserPanel('technologies', 'rb_tech_portfolio.TechnologiesPage'),. This is all working nicely. But what I want to do is to list links to these referenced pages, but I cannot seem to work out the best way to do this. The closest I have gotten is with {% for technology in page.technologies.all %} but this simply gives me the object which connects the 2 page models, whereas I want the referenced object. Is this all there ready to use, or do I need to do an extra query in def_context to do this? Thanks, Dan -
Where to build database objects in Django(without using shell)?
I have created my database models in my model.py file, but I want to be able to populate them with data. I have the code written that reads in the data from a text file I have and create the objects for my models. But I am not sure where to actually run this code, all the tutorials I can find they only create the objects through the shell, but since I am reading in from a text file and since the code is quite long I dont want to use the shell. My solution was to create a file called buildDB in my application folder, and run the code there, but this will not work: if I try to import my models at top of file using from .models import * I get ImportError: attempted relative import with no known parent package when I run it. If I try using from applicatonName.models import* I get django.core.exceptions.ImproperlyConfigured: Requested setting INSTALLED_APPS, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings. When I google the second error message, it would appear that this happens becasue I am not using manage.py shell, and … -

Django ArrayField on Frontend Form?
I'm currently in the process of rebuilding my WordPress website into a full Django web app. With WordPress, I had made great use of the awesome Advanced Custom Fields plugin, and I'm struggling to get the same functionality with Django. One field in particular with ACF is called a "Repeater Field" that lets me click a button to add another row to an array. I did manage to get something similar working with Django, but only in the Admin part. I've used this plugin "Django Better Admin ArrayField" - https://github.com/gradam/django-better-admin-arrayfield and it displays the arrayfield exactly as I want: Django Better Admin ArrayField How can I get this to work on the frontend of the site, like in a user-submitted form? -

Django and HTML : Too many values to unpack (expected 2)
I'm new to django and html and I have to do a project for school. I tried to learn how forms works with django and I think I got it django forms right. But I simply don't know how to make it work with my html. I got the too many values to unpack (expected 2). Here is the important part of my form: class ConfiguratorForm(forms.Form): queryOfProject = TypeOfProgram.objects.values('name') queryOfFramework = Framework.objects.values('name','version') listOfProject = [] listOfFramework = [] listOfFramework += queryOfFramework listOfProject += queryOfProject listFramework=[] listProject = [] for i in range(0,len(listOfFramework)): listFramework.append(listOfFramework[i]['name'] + " " +listOfFramework[i]['version']) for i in range(0,len(listOfProject)): listProject.append(listOfProject[i]['name']) typeOfTheproject = forms.ChoiceField(choices = listProject) wantedFramework = forms.MultipleChoiceField(choices = listFramework) Where listProject and listFramework are both list containing elements. And I know it is no good code but I'm learning how everything works and I haven't much time. For the html code. I absolutly don't know what exactly I wrote. I've search so lang and tried a lot of things I've seen. {% block content %} <form method="post"> {% csrf_token %} {{form}} <input type="submit" value="Submit"> </form> {% endblock %} If anyone could tell me how to correct the html file or if my form is wrong? -

How to get the child model object from the parent in Django?
I have the following models class Layer(models.Model): pass class Geometry(models.Model): layer = models.OneToOneField(Layer) class Circle(Geometry): radius = models.CharField(max_length=255) class Rectangle(Geometry): height = models.CharField(max_length=255) width = models.CharField(max_length=255) Layer has a one-to-one relationship with Geometry, that must either a Circle or a Rectangle, or one of the other 10 geometry children. I can easily get which geometry a layer currently has by doing layer.geometry, but I dont know an easy way of checking which of the geometry children it is. I can check if layer.geometry.circle exists and perform this check for all fields, but I am looking for an easier way to get child, since it is a one-to-one relationship I am guessing Django provides a better way of accessing that. Thanks in advance! -
Many to many relation entries not added by .add() method in Django

I use these to create a new Volunteer instance as volunteer = Volunteer(...) volunteer.save() volunteer.currentAddress.add(temporaryVolunteer.currentAddress.all()[0]) volunteer.permanentAddress.add(temporaryVolunteer.permanentAddress.all()[0]) volunteer.save() But when I do print(volunteer.currentAddress.all()) or print(volunteer.permanentAddress.all()), it returns an empty queryset. I also checked the admin site for confirmation and there are no entries of address on the volunteer instance. Is there any way the entries can be added with this approach? -
