Unique Class or extend Class in Python Django
In the following situation, I have a feeling I need to ?extend? the Migration class instead of re-stating it in the second module. migrations/0001_initial.py: class Migration(migrations.Migration): initial = True dependencies = [('auth', '0012_alter_user_first_name_max_length'),] operations = [ migrations.CreateModel( name='User', fields=[ ('id', models.AutoField(auto_created=True, primary_key=True, ...)), ('password', models.CharField(max_length=128, ...)), ... migrations/0002_venue.py: class Migration(migrations.Migration): dependencies = [('app', '0001_initial'),] operations = [ migrations.CreateModel( name='Venue', fields=[ ('id', models.AutoField(auto_created=True, primary_key=True,...)), ('name', models.CharField(blank=True, max_length=150, ...)), ('address', models.CharField(blank=True, null=True, ...)), ...

Can't get form to work for comment replies
I can't seem to get the post form to work for post replies (comments for a post). It works via the Django admin but I can't seem to display the form on the template which I think is due to my noobish backend. Layout of the "site": Front: Frontpage contains all posts which shows 3 latest comments for said posts (this part works). Posts: When you want to read a post it redirects you to another page which shows selected post (as normal) and here you can see all comments for the post (currently added directly via Django Admin). Here I want a form so the visitor can reply to the post. (This part does not work). Forms: from django import forms from django.forms import widgets, TextInput, ModelForm from .models import Comments, Post class PostForm(ModelForm): class Meta: model = Post fields = ['entry', 'post_image'] labels = { 'entry': "Post something spoopy:", } widgets = { 'entry': widgets.Textarea(attrs={'rows':10, 'cols':5}) } def __init__(self, *args, **kwargs): super(PostForm, self). __init__(*args, **kwargs) for name, field in self.fields.items(): field.widget.attrs.update({'class': 'input'}) class CommentForm(ModelForm): class Meta: model = Comments fields = ['comment_entry', 'comment_image'] labels = { 'comment_entry': "Answer!", } def __init__(self, *args, **kwargs): super(CommentForm, self).__init__(*args, **kwargs) for name, … -

Django TestCase with Postgresql brokes PrimaryKeys
I have setted up postgresql at my django application, and after that my TestCases had broken. It always throwed ObjectDoesNotExists at any test method after first one. I have narrowed down the issue, and each time test method is called, all objects created at setUp, get their primary keys + 1. Maybe you don't understand but see my code: class ProfileTestCase(TestCase): def setUp(self): user1 = User.objects.create(username="Unit1", email="testuser1@gmail.com", password="123456") user1_profile = Profile.objects.create(user=user1, first_name='User1', last_name='User1') def test_smth0(self): print(Profile.objects.all()) print(Profile.objects.filter(first_name='User1')[0].id) def test_smth1(self): print(Profile.objects.all()) print(Profile.objects.filter(first_name='User1')[0].id) def test_smth2(self): print(Profile.objects.all()) print(Profile.objects.filter(first_name='User1')[0].id) And here is console output for this tests Why this is happening and how to fix this. Here is my connections settings to postgresql database in settings.py: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql_psycopg2', 'NAME': 'myapp_db', 'USER': 'admin', 'PASSWORD': 'MYPASSWORD', 'HOST': '127.0.0.1', 'PORT': '' } -
What happens when an object is created in Django admin?
I am new to Django. When we learn Python it was taught that when an object is created, the init function is initialized and all the variables that are passed are saved using self keyword. For eg: class Movie: def __init__(self,name,caption,budget): self.name = name self.caption = caption self.budget = budget obj1 = Movie('Taken',"Fight movie",250) obj2 = Movie('Wanted','Comedy movie',300) print(obj1.name) print(obj2.name) Here, in the above example when I clicked the run, two objects are initialized and saved. Hence when I print both the movies names are printed. Now when I read the documentation in Django, it says that when we create an object of a model in Django admin, it calls the save function to save the instance. Until now I was in the assumption that, the dunder init will be called just like in plain Python. The Django model looks like this: class Employee(models.Model): name=models.Charfield() dept=models.Charfield() def__str__(self): return self.name Also, here I don't see any init function explicitly defined. But when I ctrl + click on the Model, I can see a number of functions defined and there is init as well as save function defined. Now I want to know which function is called when we save any object … -
Django - Searchbar in Listview | How to define and process it
i'm totally new to django and python. I would like to add a search bar working on my Listview page as I've seen on the Django admin-site. I've seen a lot of django docs, many explainations and plenty of tutorials on the web but i have to say that I'm confused and could not find a solution for my problem. What i want to do: I have a page with a (class-based)ListView that presents 5 fields from my table. I would like to add a search bar working on 2 of these 5 fields (object id and description) as i've seen on the Django admin-site. Looking at the Docs and web these are a lot of different propositions to do that(queryset, filter, context, Q...). Personally I would like to work with the context. I tried to recover info from my searchbar but what I have implemented and tried since now is not working. Could someone help me on this matter? What is the best practice and approach? Indications on how to manage this with some code exemple? Thanks in advance! #HTML <form method="GET"> <input type="text" name="q" value="" id="searchbar" autofocus> <input class="button" type="submit" value="Search"> </form> #View class AircraftListView(ListView): model = Aircraft … -

How to use clear checkbox for ajax fileupload with modelform django
i am quite a noob on django and ajax so please excuse me if there is some big mistake or ugly code in my work. So I am working on an app where the user must upload different documents in a modelForm (linked to another model in 1:1). The user will probably not upload all the documents at once. I am using ajax to have a progress bar for the user. So far, the upload works fine, replacing document with another works too, but i have a problem when it comes to using the clear checkbox that django provides when a document has already been uploaded. Using submit and standard Post, the clear checkbox works fine. Using ajax it doesnt work. models.py (not posting everything since there is over 25 FileFields) class MandatVenteUpload(models.Model): mandat= models.OneToOneField('mandat_vente.MandatVente', on_delete=models.CASCADE, primary_key=True) acte_propriete = models.FileField(upload_to=content_file_name, max_length=60 ,null=True, blank=True) carte_identite= models.FileField(upload_to=content_file_name, max_length=60 ,null=True, blank=True) diagnostic_amiante= models.FileField(upload_to=content_file_name, max_length=60 ,null=True, blank=True) diagnostic_assainissement= models.FileField(upload_to=content_file_name, max_length=60 ,null=True, blank=True) diagnostic_electricite= models.FileField(upload_to=content_file_name, max_length=60 ,null=True, blank=True) [...] views.py (using exception since if no document has been uploaded yet, the model does not exist) @login_required def mandat_vente_upload_view(request, num_mandat_upload): mandat_upload=get_object_or_404(MandatVente, id = num_mandat_upload) if mandat_upload.createur == request.user or request.user.is_staff: try: form_upload = MandatVenteUpload.objects.get(mandat=mandat_upload.id) form=MandatVenteUploadForm(mandat_upload, request.POST … -

Search list JSONField postgres Django
I have a JSONField which is an empty list ([]) by default. The data stored in the field is as follows: [{"operand":"key1","value":"value1"},{"operand":"key2","value":"value2"} and so on....] Now I want to search this JSONField and return the result if the search query is present in the values of either "operand" or "value". So for example is search query comes as "value", "value1", "key", "key2", the above mentioned record should be returned. So how to implement it in Django?
