The current path, product/, didn't match any of these
I am having trouble with connecting to url code. Everything is showing fine but after I tried to create, this error message pops up. Also, I would like to know if path function works on the django 1.x.

csrf and cors errors in localhost development of webpacked vuejs/reactjs/angularjs website with django backend
How can I run my vuejs application on localhost and have it send its API calls to my deployed django rest framework backend without getting cors and csrf issues? So far I have these issues: I can't read the cookie from browser because it's domain is not set to localhost. I need that to set the X-CSRFTOKEN header for django. I get CORS errors since localhost is not the same origin as my domain(example.com) I get error that referer does not match. -
How to crop images in django if I already have the cropping data (x,y,etc) coordinates?
I have an app where users would upload images and may crop a part of it so I added cropper.js to capture the coordinates and used a pillow code to crop it , I found it in this blogpost but nothing changes in the images I checked the data type of the coordinates and checked everything and nothing happened. from PIL import Image def crop(corrd, file ,path): image = Image.open(file) cropped_image = image.crop(corrd) resized_image = cropped_image.resize((384, 384), Image.ANTIALIAS) resized_image.save(path) return file if form.is_valid(): image = form.save(commit=False) x = float(request.POST.get('x')) y = float(request.POST.get('y')) w = float(request.POST.get('width')) h = float(request.POST.get('height')) print(x) print(y) print(w) print(h) crop((x,y,w+x,y+h),image.pre_analysed,image.pre_analysed.path) image.patient = patient messages.success(request,"Image added successfully!") image.save() class ImageForm(ModelForm): x = forms.FloatField(widget=forms.HiddenInput()) y = forms.FloatField(widget=forms.HiddenInput()) width = forms.FloatField(widget=forms.HiddenInput()) height = forms.FloatField(widget=forms.HiddenInput()) class Meta: model = UploadedImages fields = ('pre_analysed', 'x', 'y', 'width', 'height', ) so what I'm doing wrong here?

I'd like to know if the ManyToMany Field for each post contains a user ID in django

Django Rest Framework: URL for associated elements
I have the following API endpoints already created and working fine: urls.py: router = DefaultRouter() router.register(r'countries', views.CountriesViewSet, base_name='datapoints') router.register(r'languages', views.LanguageViewSet, base_name='records') Now, I need to create a new endpoint, where I can retrieve the countries associated with one language (let's suppose that one country has just one associated language). For that purpose, I would create a new endpoint with the following URL pattern: /myApp/languages/<language_id>/countries/ How could I express that pattern with the DefaultRouter that I'm already using? -
Implementing PostgreSQL HStore in Django
I found some couple of packages to implement PostgreSQL HStore in Django from djangopackages.org. The most stared and most forked package was last updated in March 2, 2017. I think it is not maintained regularly. But as it at the top of the list I am confused about that should I use it in my project or there is a better option for me. Which is the best and handy way to implement PostgreSQL HStore in Django? -

Using multiple models for django ecommerce cart

django default Authenticaiton form shows username rather than email
I implemented my own user login form with django like below from django.contrib.auth.forms import AuthenticationForm class CustomUserLoginForm(AuthenticationForm): class Meta: model = CustomUser fields = ('email', 'password') then as a view this is what I have: from rest_auth.views import LoginView from users.forms import CustomUserLoginForm class CustomLoginView(LoginView): def get(self, request): form = CustomUserLoginForm() return render(request, "api/test_template.html", context={"form": form}) in my template then, I am calling {{form.as_p}} in <form> tag to show the form input details. However, by default, this shows the username and password forms. How can I replace the username with the email? in the rest-auth, browserable api, both the username and the email are present so I know that I can do this since I am using the rest-auth LoginView as backend. Can I manually unpack {{form}} since later I would still like to style this form. How can I do this? -

Django how to use request data as form in an html template
I am using Django rest framework rest-auth for login and sign up. But I do not want to use the browseable API as my UI. I am building my own form. so I am using a custom login url like so: path('rest-auth/customlogin', CustomLoginView.as_view(), name='rest_login'), where CustomLoginView is defined as : class CustomLoginView(LoginView): def get(self, request): return render(request, "api/test_template.html") now in test_template.html, I would like to have 2 input fields: email and password. the same fields that are shown in the browserable API if I did not overwrite with the template. I am not sure how to get the request data into the template. (if email and password fields reside in the request data, is this correct?) test_template.html {% block content %} <div class="row"> <h3>Login</h3><hr/> {# I am not sure how to use input fields here where the data inputted goes in the email and password rest-auth fields#} </div> {% endblock %} -

How to use parse_qs in redirecting from view to another?
I have a home in which I have a form that I get some info from students to suggest them some programs to apply to. The home view is as below: def home(request): template_name = 'home.html' home_context = {} if request.POST: my_form = MyModelForm(request.POST) if my_form.is_valid(): # do some stuff return programs(request) else: my_form = MyModelForm() home_context.update({'my_form': my_form, }) return render(request, template_name, home_context) In the second view, I have the same form and I want this form to be pre-occupied with the information I entered in the home page. That is why in the above, I passed my POST request to programs view that is as below: def programs(request): template_name = 'programs.html' programs_context = {} if request.POST: my_form = MyModelForm(request.POST) if my_form.is_valid(): # do some other stuff else: my_form = MyModelForm() programs_context.update({'my_form': my_form, }) return render(request, template_name, programs_context) The drawback of this strategy (passing the POST request in the home view to the programs_view) is that the url in url bar does not change to 'example.com/programs' and stays as 'example.com' . I will have some problems including problems in pagination of the programs. You can check the actual project in applypro.co and applypro.co/programs . please see that how get and … -

DRF, consistent api for foreignkey relations
Suppose you want to show nested data when reading. Also suppose that you want to only allow changing the id of the foreign key. Hence the following definition arises, but the problem is they use the same variable order_case and I get when updating via {"order_case": 477}. ValueError: Cannot assign "477": "OrderCaseRevision.order_case" must be a "OrderCase" instance. class OrderCaseRevisionSerializer(serializers.ModelSerializer): order_case = OrderCaseSerializer(read_only=True) order_case = serializers.IntegerField(write_only=True) I could do the following to mitigate the problem, but I don't like the fact that you usually use foreign key name like order_case to update the foreign key field and here you are making an exception that you have to use order_case_id. class OrderCaseRevisionSerializer(serializers.ModelSerializer): order_case = OrderCaseSerializer(read_only=True) order_case_id = serializers.IntegerField(write_only=True) -
Axios send request twice, 301 and 401 results in Django Rest Framework

Any idea? -
