Some objects of django forms are not saved in database?
I created a custom register form and previously it only asked for username and password.Then I added some sections such as name , lastname and email to the user registration section. After adding these, it now doesn't happen when registering the username in the database during user registration. And also name and email information is not registered. models.py from django.db import models class Register(models.Model): first_name = models.CharField(max_length=50,verbose_name="First Name") last_name = models.CharField(max_length=50,verbose_name="Last Name") username = models.CharField(max_length=50,verbose_name="Username") email = models.EmailField(verbose_name="Email") password = models.CharField(max_length=50,verbose_name="Password") confirm = models.CharField(max_length=50,verbose_name="Confirm Password") def __str__(self): return self.title forms.py from django import forms from.models import Register class LoginForm(forms.Form): username = forms.CharField(label="Username") password = forms.CharField(label="Password",widget=forms.PasswordInput) class RegisterForm(forms.ModelForm): class Meta: model = Register widgets = { 'password': forms.PasswordInput(), 'confirm': forms.PasswordInput(), } fields = ["first_name","last_name","username","email","password","confirm"] views.py from django.contrib.auth.backends import UserModel from django.shortcuts import render,redirect from .forms import LoginForm, RegisterForm from django.contrib.auth.models import User from django.contrib.auth import login,authenticate,logout from django.contrib import messages from django.contrib.auth.decorators import login_required # Create your views here. def register(request): form = RegisterForm(request.POST or None) if form.is_valid(): password = form.cleaned_data.get('password') username = form.cleaned_data.get('username') last_name = form.cleaned_data.get('last_name') email = form.cleaned_data.get('email') first_name = form.cleaned_data.get('first_name') newUser = User(username = username) newUser = User(first_name = first_name) newUser = User(email = email) newUser = User(last_name … -
Change django language code from URL pattern
I have this languages code setup on my Django application. LANGUAGES = [ ('en', _('English (US)')), ('de', _('Deutsch')), ('fr',_('Français')), ('ja',_('日本語')),# -> JP ('ko',_('한국어')),# -> KR ] And on the url patterns i have the following setup: urlpatterns = i18n_patterns( path('', include('main.urls')), prefix_default_language=False ) So my application has the languages folder prefixed on the URLs. But i need the languages ja and ko to work from other prefixes, jp and kr, respectively. I tried using a middleware to override the request.path_info and the site responds on the required urls but it builds the internal links on the bad urls. -

Adding an Array to an a href link using Javascript/Jquery
I'm currently writing a functionality, whereby the users will click on a particular email and this will be added to a list in the local storage, thereafter, the user will click a button, essentially that button should popular a href tag, so that all the mail addresses are copied to user's default email settings (in my case outlook). My question is how do you convert this into an email format?, I have tried loading it into the tag and it works, but then Django interprets this as a URL, not a mailing list? So far I have the following: <td class="virtualTd" onclick="putThis(this)">{{ client.email }}</td> <script> const emails_list = [] function putThis(control) { var email = control.innerText; emails_list.push(email); } </script> This populates an array with all the addresses, Thereafter, the user can click this button to load the data in to local storage, with the ultimate intention to load the outlook email <a href="#" id="sendEmail" class="btn btn-primary" onclick="popEmail()"> Email Client </a> <script> function popEmail() { const jsonArr = JSON.stringify(emails_list); localStorage.setItem("array", jsonArr); const str = localStorage.getItem("array"); const parsedArr = JSON.parse(str); console.log(parsedArr); var a = document.getElementById('sendEmail'); a.href = parsedArr; } </script> -

Fetched objects from django are displayed as numbers/ids
I'm using React frontend and Django backend. I've managed to make it so users can add rats to their account, however when I wanna fetch details about the rats the details are displayed as numbers, I'm assuming the id of the detail? Here's an example. This is what you get if you view one of the rats, frontend-wise: User: 12, Rat Name: newrat Rat Body colour: 3, Eye colour: 3 So as you can see, you get the id (?) of each detail except the rat name. It belongs to the user with the id of 12, and the 3rd body colour created, etc. Here's my models: class EyeColour(models.Model): name = models.CharField(max_length=255) def __str__(self): return self.name class BodyColour(models.Model): name = models.CharField(max_length=255) def __str__(self): return self.name class rat(models.Model): name = models.CharField(max_length=132, null =True) body_colour = models.ManyToManyField(BodyColour, related_name='bodycolour') eye_colour = models.ManyToManyField(EyeColour, related_name='eyecolour') user = models.ForeignKey(User, on_delete=models.CASCADE, null = True) def __str__(self): return self.name Serializers: class EyeColourSerializer(FlexFieldsModelSerializer): class Meta: model = EyeColour fields = '__all__' class BodyColourSerializer(FlexFieldsModelSerializer): class Meta: model = BodyColour fields = '__all__' class RatSerializer(FlexFieldsModelSerializer): class Meta: model = rat # fields = '__all__' exclude = ['bio'] # read_only_fields = ['eye_colour', 'body_cdolour'] expandable_fields = { 'EyeColour': ('accounts.EyeColourSerializer', {'many': False}), 'Image': ('accounts.ImageSerializer', … -

How do I host a function in a web server, which returns a value back to the client?
I made an ML model that classifies images, and I want to implement it to my application. But the problem is that the file is too heavy and requires an unreasonable amount of disk space for an android application. So I was wondering if I could host the Model function in a server, which would return the prediction back to the client, when I can call from my python script. I couldn't find any specific tutorials on hosting functions, with would return output back the the client. So How do I go about doing this? Here is the function I wish to host- from keras.models import load_model from PIL import Image, ImageOps import numpy as np labels= ["Banana", "Fan", "Clock","Coin","Leaf","Paper_airplane","Pen","Phone","Spoon","Tomato"] model = load_model('keras_model.h5') data = np.ndarray(shape=(1, 224, 224, 3), dtype=np.float32) #Here I wish to pass the image, from my python program, and recieve the prediction def RunPrediction(img): image = img size = (224, 224) image = ImageOps.fit(image, size, Image.ANTIALIAS) image_array = np.asarray(image) normalized_image_array = (image_array.astype(np.float32) / 127.0) - 1 data[0] = normalized_image_array #And I want to recieve this output in my code prediction = model.predict(data) return prediction -
Parsing data from django backend into react component
Hi I am trying to parse JSON data from Django view into the frontend. Basically in my view, I defined the data which I want to parse and it looks like this : user_information = {'username':request.user.username, 'email':request.user.email, 'first_name':request.user.username} Then in the html, I can parse it into the javascript using json_script which looks like this: {{ user_information|json_script:'user_information' }} Then I want to call the user_information variable in React component using this script: class Form extends React.Component { constructor(props){ super(props); this.state = { user_information: null }; } componentDidMount() { this.setState({ user_information: JSON.parse(document.getElementById('user_information').textContent) }); console.log(this.state.user_information); } render () { return( <h1>{this.state.user_information}</h1> ); } } To test tis out I tried to print it in the console to see whether it is successfully parsed to the component state. But it turns out that in the console I got null. Can you guys help me what are my mistakes and how do I solve it ? -
