Encoding error when trying to open json file from django app
I have a json file in the same directory with my app where i have saved some names and passwords. When a user clicks a button, i m trying to retrieve these data and compare it with the input he gave. However, i get an encoding error JSONDecodeError: Expecting value: line 1 column 1 (char 0) The thing is i can normally run the code and read from the json without problems when i dont use Django, so it has to do with it probably. I tried adding errors='ignore' and change encoding withotu succcess My login function which opens the json file: def login(name,password): with open('data.json', 'r', encoding='utf-8', errors='ignore') as f: try: data = json.loads(f.read()) print(data) except ValueError: # includes simplejson.decoder.JSONDecodeError print('Decoding JSON has failed') return False f.close() -
Do checkboxes have to be under one div to work properly?
I have some checkboxes which are generated dynamically with django template. Some of them are under one div and some under another. When making the first or last one required and clicking submit on my form it says that at lease one of the checkboxes from the second div has to be checked and vice versa. The name of the checkboxes are the same. Here's the code <div class="row"> <div class="col"> {% for value in key.categories %} #code.. if first half of items <input type="checkbox" name="{{ key.id }}[]" value="{{ value.id }}" id="{{ value.id }}"> <label for="{{ value.id }}">{{ value.value }}</label><br> #code.. if middle item <input type="checkbox" name="{{ key.id }}[]" value="{{ value.id }}" id="{{ value.id }}" required> <label for="{{ value.id }}">{{ value.value }}</label><br> </div> <div class="row"> #code.. if second half of items <input type="checkbox" name="{{ key.id }}[]" value="{{ value.id }}" id="{{ value.id }}"> <label for="{{ value.id }}">{{ value.value }}</label><br> {% endfor %} </div> </div> As stated on the question, my question is whether the checkboxes have to be under one div. If so, how can I print the items in two columns of the same length? -

Django rest serializer JSON field sets field to None on valid data
I have a model named project that contains a JSON field named pilot_circles, I am trying to patch that field using a detail_route view, and a model serializer that only contains that field.

DRF POST Request return 201 but nothing get's created
I'm trying to create a new Attendance object using the POST method through the python requests library.

Django Djoser: Email address reset
I am using username for primary identification. However, users also have email addresses. I would like to know how can I set up "email address reset" so that users can change their email addresses. This functionality seems obvious to me but I did not find anything - am I missing something or maybe my approach is not correct? Oh, and I would like to keep the username as is, I just want to make it possible to change the email with confirmations etc. I think it is important to have an email sent to the new address first and only then change it. Any help will be much appreciated. Thank you in advance. -

Problems with Django Url Patterns
I am having some difficulty with Django url patterns. I am relatively new to Django. So, I am trying to get used to best practices when it comes to building apps using Django. Now, here is my problem. Often time I did notice when two of my urls have kind of similarity, Django often confuses them and I have to make one of the url extremely distinct so that it can work. Why is that ? Even though I have explicitly mentioned as to which url a specific form should be posted. Here is a bug that I am facing url(r'book/collection/read/$', ReadBookList.as_view(), name='read_book_list'), url(r'book/(?P<pk>\w+)/$', BookDetail.as_view(), name='book_detail'), <li class="nav-item active"> <a class="nav-link" href="{% url 'library:read_book_list' %}"> <i class="fa fa-check-circle"></i> <span>Books You Read</span></a> </li> Now, when I navigate to that link, it keeps going to detailview instead of the other url. What could I be doing wrong ? And what is a better way to work with url patterns so that Django doesn't confuse mapping to a wrong url. E.g list of urls in my library app # Book urlpatterns url(r'book/$', BookList.as_view(), name='book_list'), url(r'book/add/$', BookCreate.as_view(), name='book_create'), url(r'book/(?P<pk>\w+)/$', BookDetail.as_view(), name='book_detail'), url(r'book/(?P<pk>\w+)/edit/$', BookUpdate.as_view(), name='book_update'), url(r'book/(?P<pk>\w+)/delete/$',BookDelete.as_view(), name='book_delete'), url(r'book/collection/read/$', ReadBookList.as_view(), name='read_book_list'), url(r'book/mark/read/$', book_mark_read, name='mark_read'), url(r'book/search/results/$',BookSearch.as_view(), name='book_search'), … -
How to use PUT to update something in Vue using Django REST framework
I am new to Vue but have experience with Django. I am using this boilerplate from Github: https://github.com/gtalarico/django-vue-template I really like the structure of that boilerplate because it is not overwelming at all and not a lot of code is written to succesfully interact with the back-end API of Django. It has GET, POST & DELETE already pre-installed and connected to Django REST. So far so good. However I try to add a PUT method to it so I can update models. I try to follow the same structure but I can't get it to work. My productService.js: import api from '@/services/api' export default { fetchProducts() { return api.get(`products/`) .then(response => response.data) }, postProduct(payload) { return api.post(`products/`, payload) .then(response => response.data) }, deleteProduct(proId) { return api.delete(`products/${proId}`) .then(response => response.data) }, updateProduct(proId) { return api.put(`products/${proId}`) .then(response => response.data) } } The updateProduct is the new code I added. Then in store --> products.js: const actions = { getProducts ({ commit }) { productService.fetchProducts() .then(products => { commit('setProducts', products) }) }, addProduct({ commit }, product) { productService.postProduct(product) .then(() => { commit('addProduct', product) }) }, deleteProduct( { commit }, proId) { productService.deleteProduct(proId) commit('deleteProduct', proId) }, updateProduct( { commit }, proId) { productService.updateProduct(proId) commit('updateProduct', … -

Serializers vs views to retrieve object by foreign key field
I'd like to allow users to perform POST request to create a blog post, and to use the topic name instead of the topic id as a foreign key. A minimal model might look as follows. models.py class Topic(models.Model): name = models.CharField(max_length=30, unique=True) description = models.CharField(max_length=100) class Post(models.Model): name = models.CharField(max_length=30) topic = models.ForeignKey(Topic, on_delete=models.PROTECT) created_on = models.DateTimeField(blank=True, auto_now_add=True, editable=False) Now there are 2 possible approaches that I've considered: 1) Keep the views simple. views.py class PostList(ListCreateAPIView): queryset = Topic.objects.all() serializer_class = PostSerializer serializers.py class PostSerializer(serializers.ModelSerializer): topic_name = serializers.CharField() class Meta: model = Topic fields = ('name', 'topic_name', 'created_on') read_only_fields = ('created_on',) def validate_topic_name(self, value): """Verify that the topic exists.""" if not Topic.objects.filter(name=value).exists(): raise serializers.ValidationError("Specified Topic Name does not exist!") else: return value def create(self, validated_data): """Create a Post.""" topic_name = validated_data.pop('topic_name', None) topic = Topic.objects.get(name=topic_name) return Post.objects.create(topic=topic, **validated_data) 2) Keep the serializers simple. views.py class PostList(ListCreateAPIView): queryset = Post.objects.all() def create(self, request, *args, **kwargs): serializer = self.get_serializer(data=request.data) if not serializer.is_valid(): return Response( serializer.errors, status=status.HTTP_400_BAD_REQUEST) topic = get_object_or_404(Topic, name=serializer.data['topic_name']) post = Post.objects.create( name=serializer.data['name'], topic=topic) return Response({'name': serializer.data['name'], 'description': serializer.data['topic_name']}, status=status.HTTP_201_CREATED) serializers.py class PostSerializer(serializers.ModelSerializer): topic_name = serializers.CharField() class Meta: model = Topic fields = ('name', 'topic_name', 'created_on') read_only_fields = ('created_on',) My … -

But when I am accessing the attribute using the django shell I am getting an error from django.contrib.auth.models import User users = User.objects.all() users[6].email Output : masterhimanshupoddar@gmail.com # success users[6].status Error: AttributeError Traceback (most recent call last) <ipython-input-7-c9d2701fa919> in <module>() ----> 1 users[6].status AttributeError: 'User' object has no attribute 'status' Here is my forms.py from django.contrib.auth.forms import UserCreationForm from django import forms from django.contrib.auth.models import User class SignUpForm(UserCreationForm): STATUS_CHOICES = ( (1, ("CEO")), (2, ("Dev Manager")), (3, ("Testing Manager")), (4, ("Developer")), (5, ("Test Engineer")) ) email = forms.EmailField(required=True, label='Email', error_messages={'exists': 'Oops'}) status = forms.ChoiceField(choices = STATUS_CHOICES, label="Designation", initial='Developer', widget=forms.Select(), required=True) class Meta: model = User fields = ("username", "email", "password1", "password2", "status") def save(self, commit=True): user = super(UserCreateForm, self).save(commit=False) user = super(UserCreateForm, self).save(commit=False) user.email = self.cleaned_data["email"] user.status = self.cleaned_data["status"] if commit: user.save() return user Why … -
Django check username at sign-up against a regex of allowed usernames
i would like to check the username upon signup against a regex (which is currently not a regex, see code below). I don't want a new user to use usernames like "admin, supporter, staff" etc. I just try'd to write myself a validator for this but sadly i didn't work with regex or a validation like this before as i'm quite new to coding, maybe smb. can help me out on this: models.py class User(AbstractBaseUser): ... user = models.CharField(verbose_name='Username', max_length=20, unique=True, validators=username_filter) ... validators.py from django.core.exceptions import ValidationError from django.core.validators import RegexValidator def username_filter(value): invalid_username_regex = RegexValidator( regex=("admin", "staff", "supporter", "support") ), if value in invalid_username_regex: raise ValidationError(u'Its not possible to signup with a username like this, please try a different one') but currently i get the following error: user = models.CharField(verbose_name='Username', max_length=15, unique=True, validators=username_filter) File "/venv/lib/python3.7/site-packages/django/db/models/fields/init.py", line 1039, in init app | super().init(*args, **kwargs) File "/venv/lib/python3.7/site-packages/django/db/models/fields/init.py", line 171, in init app | self._validators = list(validators) # Store for deconstruction later TypeError: 'function' object is not iterable thanks in advance
