How to implement multiple forms for one template
I'm new to Django. I have multiple forms for different calculations (etc Form1, Form2, Form3, ...) on my blog page. Each blog post (post/1) will have a button at the page with a link to open specific form template (post_form.html) for that post (e.g. post/1/form/) with a form in it. (Post1 - Form1, Post2 - Form 2, etc..) Could someone help with the logic of implementation of this? How to better set up urls, models and forms? models.py class Post(models.Model): title = models.CharField(max_length=100) content = models.TextField() date_posted = models.DateTimeField(default=timezone.now) category = models.ForeignKey(Category , on_delete=models.CASCADE, default='Concrete') author = models.ForeignKey(User , on_delete=models.CASCADE) image = models.ImageField(default='default.jpg', upload_to='calc_pics') formId = models.IntegerField() class L_section_prop_calc(models.Model): name = models.CharField(max_length=100, unique=True) tf = models.DecimalField(max_digits=5, decimal_places=3) tw = models.DecimalField(max_digits=5, decimal_places=3) height = models.DecimalField(max_digits=5, decimal_places=3) urls.py path('post/<int:pk>/', PostDetailView.as_view(), name='post-detail'), forms.py class Calc_L_Section_Prop_Form(forms.ModelForm): class Meta: model = L_section_prop_calc fields = ['tw','tf','height'] I'm do not know if I need to create a model for each form. Is there a better way? Thx -

Field error for invalid user and Value error for new user registration in DJANGO

Django import_export decode ascii code on submit?
Im trying to upload and import data into models from a csv file that contains special ASCII characters, for example "Big Fish Äö√Ñ√¥s", the django import_export would give me an error that reads: Imported file has a wrong encoding: 'utf-8' codec can't decode byte 0x80 in position 511: invalid start byte. This error would show when I select the file and click submit. The feature Im trying to implement would take a csv file that contains thousands of row of data, I was wondering if there is a way that I can go through each row level and clean the data line by line. I have tried implmenting the before_import_row method, but it doesn't seems to be called. my admin.py: '''ptyhon from django.contrib import admin from import_export.admin import ExportActionModelAdmin, enter code hereImportExportMixin, ImportMixin from import_export.resources import ModelResource from .forms import CustomConfirmImportForm, CustomImportForm from .models import Author, Book, Category, Child, EBook class ChildAdmin(ImportMixin, admin.ModelAdmin): pass class BookResource(ModelResource): class Meta: model = Book def for_delete(self, row, instance): return self.fields['name'].clean(row) == '' class BookAdmin(ImportExportMixin, admin.ModelAdmin): list_filter = ['categories', 'author'] resource_class = BookResource class CategoryAdmin(ExportActionModelAdmin): pass class AuthorAdmin(ImportMixin, admin.ModelAdmin): pass admin.site.register(Book, BookAdmin) admin.site.register(Category, CategoryAdmin) admin.site.register(Author, AuthorAdmin) ''' my models.py '''python [![import random import string … -
Python Dictionary should return a value rather than None
I have a csv file which consists a,b 2,3 4,5 4,7 4,7 (where a,b is a column values) Below i have two functions where the first function will read the csv and assign 'a' as key and 'b' as value in a dictionary Second function i will pass 'a' value as an argument and it returns b as a value when i use that function.If there is no value for 'a' i get None. def x (id): dict1= {} with open(file, 'r', encoding='utf') as f: for i in csv.DictReader(f, skipinitialspace= True) dict1[i['a']] = row['b'] print('im happy now' ) def getx (a): return dict1.get(a, None) It works perfectly. Now I have a csv file with four column values a,b,c,d 1,2,r,4 2,g,4,6 3,d,4,6 For this i have written a code like def x (): dict1= {} with open(file, 'r', encoding='utf') as f: for i in csv.DictReader(f, skipinitialspace= True) dict1[i['a']] = dict(dict1[i['b']] = dict(dict1[i['c']] = row['d'])) print('im happy now' ) def getx (a): return dict1.get(dict1['a']['b']['c'], None) My logic is to show dict1[i['a']] = dict(dict1[i['b']] = dict(dict1[i['c']] = row['d'])) as dict1 :{ 'a':{ 'b':{ 'c':2, 'c':4, 'c':4 } } } I'm not sure if what i have written above is right.

Looping through two arrays and adding the collection of each into new array without dups
I have two arrays that I want to loop through. Array A and Array B. I want to add the elements of both array into a new Array that contains the collection of all elements in that array without any duplication. This will be written in python. For Example A = [1,2,3,4] B = [1,5,6,7] Collection = [1,2,3,4,5,6,7] I was wondering if there's a faster and more efficient to do it without looping through each indexes and comparing it and then storing it. Because that's what I'm planning to do but I think it will take really long time given that I have about a couple thousand elements in each array. -

Python / Django / channels.exception.ChannelFull() error
We constantly get a channels.exception.ChannelFull() error when we run our setup. Traceback Our setup consists of: Server Computer Client Computer The Client connects via websocket to the Server. It sends and receives to the Server over this link. The Server runs Django with Redis (channels-redis) and Channels2 in ASGI mode. When a client connects, the specific.channel_id is stored in our database. When a client disconnects, it is removed from our database. We run a BackgroundScheduler Job at 5 second intervals. This Job gets the clients in the DB and sends each one (via specific.channel_id) a message. The Client receives this message over websocket, processes it, and sends the requested data back to the Server where it is processed through a WebsocketConsumer. When developing, we ran short tests (<2 min). It wasn't until later when we were running longer tests (2+ mins) that we started to encounter this error. What might we have missed? -

Django Student-Teacher ManyToMany relationship
