How do I change my profile image in django?
I'm Trying to develop a social website, and in my user profile page I want to display the user's selected image from the registration page. I provided a default.jpg in my media folder in case the user dosen't want to upload an image. But everytime I'm trying to register a new user, even if I'm selecting a different image, the default image is being displayed. Can anyone please help me out? my models.py from django.db import models from django.contrib.auth.models import User from PIL import Image class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) image = models.ImageField(default='default.jpg', upload_to='profile_pics') CHOICES = ( ('AB+', 'AB+'), ('AB-', 'AB-'), ('A+', 'A+'), ('A-', 'A-'), ('B+', 'B+'), ('B-', 'B-'), ('O+', 'O+'), ('O-', 'O-'), ) bloodgroup = models.CharField(max_length=100, choices= CHOICES) bio = models.TextField(max_length=300) def __str__(self): return f'{self.user.username} Profile' def save(self): super().save() img = Image.open(self.image.path) if img.height > 300 or img.width > 300: output_size = (300, 300) img.thumbnail(output_size) img.save(self.image.path) my forms.py from django import forms from django.contrib.auth.models import User from django.contrib.auth.forms import UserCreationForm from .models import Profile class UserRegisterForm(UserCreationForm): email = forms.EmailField() class Meta: model = User fields = ['username', 'email', 'password1', 'password2'] class ProfileForm(forms.ModelForm): class Meta: model = Profile fields = ('image', 'bloodgroup', 'bio') class UserUpdateForm(forms.ModelForm): email = forms.EmailField() class … -
Django: can't get the url for update action to work with ModelViewSet
I am using ModelViewSet and Modelserializer for a blog like project. It could be my difficulty in understanding the implementation; I can't get the update action to work via calling it through router, only the list action is working with the route I have defined. When I put the url : 127.0.0.1:8000/api/blogs/1, to return the blog with ID 1 to edit, it returns {"Detail": "Not Found."}. This is my view: class ArticleViewSet(viewsets.ModelViewSet): queryset = Article.objects.all() serializer_class = ArticleSerializer I have also overridden the save and update methods in the serializer class, don't know whether it was needed for ModelViewSet in ModelSerializer. class ArticleSerializer(serializers.ModelSerializer): def create(self, validated_data): article = Article.objects.create( article_title = self.validated_data['article_title'], article_content = self.validated_data['article_content'], ... ) return article def update(self, instance, validated_data): instance.article_title = validated_data.get('article_title', instance.article_title) instance.article_content = validated_data.get('article_content', instance.article_content) ... instance.save() return instance class Meta: model = Article fields = ... And the urls.py file: router = DefaultRouter() router.register(r'blogs', ArticleViewSet, basename='articles-list') urlpatterns = router.urls My question is: 1. How do I specify urls for the ModelViewSet actions (in my case the update action)? 2. Will defining only one url suffice all my needs with every ModelViewSet actions? if so how? What am I doing wrong? I'm new to … -

Redis Flushall command in Heroku Scheduler (Python/Django Project)
For a Django application, I want Heroku Scheduler to perform the following commands: heroku redis:cli flushall exit (ctrl-c) I do this myself once a day now in terminal, but it would be a lot easier if I can schedule these commands.

How to open an uploaded saved file in another template?

How to make a web app using both django and express? How would you interchange data between the two platforms?
I was trying to make a web app with a complicated idea and at some point realised that I couldn't do it alone. When, I started to look around for friends with a skill set with node in their bag, I found out that everyone had experience with pure php or django. I was thinking if I could make the web app by combining different backend technologies. But I can't really understand where and how to start. What would I need to learn? How would I exchange values or data between the two frameworks or programming languages? What things would I have to learn? Where would I start? -

Django compare Datefield in template
I am trying to make a Django template page that uses Chart.js. The idea is that it would have fields for the user to add 'From' and 'To' date range to pass to Django template data to fill the Chart.js. In order for me to figure out how to do that I need to know how to compare dates in Django templates but I can't seem to figure it out, again the below is just a test to figure out how you would compare dates in a template, simplified so I can try the harder parts. entriesFuel.0.day is equal to March 5, 2020 and is a Django form DateField. I have tried the below {% if entriesFuel.0.day == "5 March 2020" %} <h1>{{entriesFuel.0.day}}</h1> {% else %} <h1>{{entriesFuel.1.day}}</h1> {% endif %} {% if entriesFuel.0.day == "March 5, 2020" %} <h1>{{entriesFuel.0.day}}</h1> {% else %} <h1>{{entriesFuel.1.day}}</h1> {% endif %} {% if entriesFuel.0.day == "2020-03-05" %} <h1>{{entriesFuel.0.day}}</h1> {% else %} <h1>{{entriesFuel.1.day}}</h1> {% endif %} Is it possible to compare the data this way or am I barking up the wrong tree by doing it this way?

In my Django template, I am retrieving the data from DB and displaying it in table format. Now, when I click on "Name" field, I want to show some data of that person. Initially, while displaying, only the table should be visible, which means the data of the particular person should remain hide and when I click on that person's name, the information about that person should be shown. Now, I have 2 problems. 1st is, when I click on any name, the information about all the persons gets displayed. For example, if there are 3 entries in my DB and if I click on the name of any person than the information about all the 3 people will get displayed. I just want to display the information of the person on which I clicked on. And the second problem is that after clicking on the name, the data is displayed on the top of the table. I want that suppose I am clicking on the second row, then the information should be displayed below the 2nd row and above the 3rd row. <table> <tr> <th>id</th> <th>Name</th> <th>Status</th> </tr> {% for records in obj %} <tr> <td>{{records.id}}</td> <td id="pop">{{records.name}}</td> <div …
