Apply django authentication for all views
I am trying to implement Django basic authentication for all of the views in my views.py file. Although I can add the authentication code snippet in every view, but it will not be easy to apply this to upcoming views. Is there any way that every view in my views.py will automatically check for the authentication? views.py def mgmt_home(request): ############################################################## # This code is repetitive ############################################################## if request.user.is_anonymous: return redirect("/login") ############################################################## test_name = Test.objects.all()[0].test_name metadata = { "test_name": test_name, } return render(request, "mgmt_home.html", metadata) Is there any way where I can avoid this repetitive code in all of my views? -
I need a text when your login "Your password incorrect"
Can you help me to understand logic : I need when I enter have a message near login form "Your password incorrect" "Your login incorrect. I have a base registration form with this messages: class RegistrationForm(auth_forms.UserCreationForm): """ A form that creates a user """ error_messages = { 'password_mismatch': 'Password mismatch.', } password1 = forms.CharField( label='Password', strip=False, widget=forms.PasswordInput(attrs={'autocomplete': 'new-password'}) ) password2 = forms.CharField( label='Access password', widget=forms.PasswordInput(attrs={'autocomplete': 'new-password'}), strip=False ) I think to write the same for login : Class AuthForm(AuthenticationForm): error_messages = { 'password_mismatch': ("Password mismatch" ), 'invalid_login': ("Invalid login"), } But I think it is not correct. my views.py this: class BaseRegistrationView(ActivationEmailMixin, generic.FormView): form_class = RegistrationForm @transaction.atomic def form_valid(self, form): self.new_user = form.save(commit=True) self.new_user = authenticate( username=form.cleaned_data['email'], password=form.cleaned_data['password1'], ) login(self.request, self.new_user) self.send_activation_email() return super().form_valid(form) # new class BaseLoginView(LoginView): authentication_form = AuthForm And html in templates: {% if field.is_hidden %} {% render_field field %} {% else %} <div class="form-group"> <label class="form-group__label"> {{ field.label }} {% if field.field.required %}* {% endif %} </label> {% if field.field.widget.input_type == 'checkbox' %} {% render_field field class="form-group__control" %} {% else %} {% render_field field class="input form-group__control" %} {% endif %} {% if field.errors %} {% for error in field.errors %} <div class="form-group__error"> {{ error }} </div> … -
Show error for django unique_together in CreateView form
I'm using Django CBV CreateView and have a unique_together setting on the model class Meta: unique_together = ('field1', 'field2',) When the user adds a non-unique new record, it triggers an error at the database level, which is a 500 error. I'd like to instead just explain to the user that their entry was a duplicate and to add something else. Any idea for an easy way to do this with CBV and the unique_together setting (or a validator)? I'd like to keep this at the model level so the unique check happens regardless if the user creates, edits, or if an admin does it in the Django admin. Thank you! -
Django client.cookies is empty, but when visiting the url there is clearly a CSRF token assigned as a cookie
Django 3.2, python 3.8 I have a function that forces a login so I can grab data from a protected API. Here is the code: def force_client_login(client, base_url): url = urljoin(base_url, '/login/') client.get(url, allow_redirects=False) print(client.cookies) csrftoken = client.cookies['csrftoken'] login_data = { 'username': 'HIDDEN', 'password': 'HIDDEN', 'csrfmiddlewaretoken': csrftoken, } response = client.post(url, data=login_data) For some reason, the client.cookies is printing [] / an empty array. When I visit the URL (which I printed out and verified it is correct), I can clearly see there is a cookie and that it is the CSRF token, I can see this by looking in the browser dev console under networking and looking at the get request. This function worked on a python 3.6 version of the same project I had running on multiple separate machines. Any thoughts? -
Django kills older requests
I am running a Django website over IIS. When a user saves an object it can take some time, so rather than have them wait for it to finish an AJAX request is sent to the server with the submission information and the page is immediately redirected. However, if the server gets many more requests that old saving request is killed rather inelegantly. The log files show that it ends mid execution with no error messages or other indication that it failed. How do I keep older requests alive in Django? P.S. I have already investigated starting a new multithreading Process but encountered issues around Django models, and I am looking for something more simple than Celery. -
Field 'id' expected a number but got <customerlogin: customerlogin object (4)>
I am trying to add customer and salon to their respective tables according to what option is selected by the user.I gave "Customer" and 'Salon owner" in dropdown menu.The name given in dropdown menu is "category". If a user select "Customer" from dropdown menu, registration form details should be added to customerlogin and customerreg tables.Similarly, in the case of "Salon owner".But unfortunately when any of these two option is selected,details were added to both customerlogin table and salonlogin table but not to other two tables.

Django, create form that has copy and paste ability from Excel
As the title states I want create a django from that allows a user to copy and paste data from excel to the form. Right now I just have a very basic form from django import forms from .models import CATEGORIES, Generator class GeneratorForm(forms.ModelForm): class Meta: model = Generator # fields exclude = {'save_id', 'user', 'create_date', 'data_table', 'save_name'} widgets = { 'category': forms.Select(attrs={'class': 'form-check-label', }, choices=CATEGORIES), } And also a very basic html page. <main role="main" class="container"> <div class="d-flex align-items-center p-3 my-3 text-white-50 bg-dark rounded box-shadow"> <div class="lh-100"> <h2 class="mb-0 text-white lh-100">Generator</h2> </div> </div> <div> <form action="" method="post"> <div class="form-check"> {{form.category|as_crispy_field}} </div> <br> <input type="submit" class="btn btn-success text-right" value="Submit"> </form> </div> </main> How would I go about adding another form item/items in my Generator form to be able to take in a 3 column excel table (via copy paste mechanic). Would I need to use js as well to get this done? Apologies in advanced for the minimal amount of code. Kinda new to this Django thing. -

Printing Output from an External Python Script on Django Webpage
I have incorporated an external python script into my Django webpage. I am currently able to display the output of my script in the terminal once a button is clicked, but I want my script to be displayed on my webpage once the button is clicked.

Adding Abstract Models support to django-rest-framework-mongoengine
In a Django project I am using mongoengine that provides Django style models to MongoDB collections. I am also using django-rest-framework-mongoengine witch extends DRF to support Documents, EmbeddedDocuments, DynamicDocuments and DynamicEmbeddedDocuments the MongoEngine model representation of MongoDB. While Django and DRF allow for using abstract classes in the Models. This is now supported by DRF-mongoengine. However i believe it is possible to add support for abstract Models by writing custom Serializers. So far I was unable to succeed and I would appreciate your help in getting this to work. class Entry(Document) meta = { 'abstract': True, 'allow_inheritance': True, } text = StringField() class Post(Entry) meta = { 'allow_inheritance': True, } class comment(Entry) meta = { 'allow_inheritance': True, } post = ReferenceField(Post) # No Problem serializing this # for the sake of Demonstration, related is a list of posts and comments related = ListField(ReferenceField(Entry)) # This is not supported by DRF-mongoengine class PostSerializer(DocumentSerializer) # Works class Meta: model = Post fields = '__all__' class PostsViewSet(ModelViewSet): serializer_class = PostSerializer queryset = Post.objects.all() class CommentSerializer(DocumentSerializer) # Fails class Meta: model = Comment fields = '__all__' class CommentsViewSet(ModelViewSet): serializer_class = CommentSerializer queryset = Comment.objects.all() What I am currently trying to do is to write … -

Django: Allow data entry into only one of multiple fields of a model
I have a model that needs to be able to store some data. The trouble is, that data may be a number, string, choice or textfield. My models.py looks something like this: class Period(models.Model): """The quarter and the year. May be visualized as the X axis.""" pass class FSLI(models.Model): """Financial statement line items. May be visualized as the Y axis.""" data_type = models.CharField(max_length=20, choices=DATA_TYPE, default='number') class Company(models.Model): """The company to which the data relates. May be visualized as the Z axis.""" pass class FSType(models.Model): """Consolidated or standalone. May be visualized as the report filter.""" pass class Datapoint(models.Model): """A single cell in the above table that points to some data.""" period = models.ForeignKey("Period", on_delete=models.CASCADE, related_name="period_dps") fsli = models.ForeignKey("FSLI", on_delete=models.CASCADE, related_name="fsli_dps") company = models.ForeignKey("Company", on_delete=models.CASCADE, related_name="company_dps") fstype = models.ForeignKey("FSType", on_delete=models.CASCADE, related_name="fstype_dps") number = models.FloatField(null=True, blank=True) text = models.CharField(max_length=255, blank=True) choice = models.CharField(max_length=20, choices=DP_CHOICES, blank=True) # Another model will store choices bigtext = models.TextField(max_length=4000) Each Datapoint may contain value only for ONE of number, text, choice or bigtext. The type of data will be determined by the data_type field of the FSLI object. Is there some simple way to ENFORCE this? Maybe by splitting up the Datapoint model into multiple models? -
Django Template Syntax Error - Django Webpack

How to add bootstrap img-fluid class to images using django-quill-editor
I am working on a blog project with Django using the django-quill-editor. Like the documentation says, I have imported QuillField and added it to my model as shown below. I have also added it to my admin. Now the problem is that whenever i insert an image into the content field of the editor, The image is displayed fully on the details page of the blog. the image is not contained in any div, making it look out of proportion. I realize this is happening because the bootstrap class 'img-fluid' is not applied to the image. I want the image to fit into the text area. So I want know how to customize django quill editor to do this.

So for example. If I click on "XYZ sent you a message", I should be able to see what the message is in a pop-up modal. The HTML code I have written sho far: {%for elements in messages %} <ul class="list-group shadow p-3"> <li class="list-group-item"> <img src="{{elements.sender.userprofile.profile_pic.url}}" width="40px" height="40px"> {{elements.sender}} sent you a message </li> <button data-toggle="modal" data-id="{{ elements.pk }}" data-target="#myModal1" class="open-my-modal"> View </button> </ul> {%endfor%} The Modal that should show the message. <div class="modal" id="myModal1"> <div class="modal-dialog"> <div class="modal-content"> <!-- Modal Header --> <div class="modal-header"> <h4 class="modal-title">Ending Survey</h4> <button type="button" class="close" data-dismiss="modal">&times;</button> </div> <!-- Modal body --> <div class="modal-body"> {{elements.message1}} <h5>here mate</h5> </div> </div> </div> </div> I have tried countless ways.

partial sync of model in django-elasticsearch-dsl
I'd like to do a "partial sync" of model between django and elasticsearch using this library (or any other module for that matter - please suggest). What I mean by "partial sync" is: on the elasticsearch side I have an index with fields _id, FIELD0, field1, field2... on the django side I have a model with fields id(primary key), FIELD0, fieldA, fieldB... I would like to have field0 changes pushed to elasticsearch side whenever it changes on django side. With what I have currently: # in documents.py from django_elasticsearch_dsl import Document as elastic_Doc from django_elasticsearch_dsl import fields from django_elasticsearch_dsl.registries import registry @registry.register_document class elastic_Document(elastic_Doc): class Index: name = 'some_index' settings = {'number_of_shards': 1, 'number_of_replicas': 0} class Django: model = SomeModel # just one field to the elastic index # this unfortunately removes other fields... fields = ['FIELD0'] the fields that I don't specify to be synced get wiped out on the elasticsearch side. Any suggestion of how this could be achieved would be very appreciated. -
Django JsonField filter by two fields
class Blog: values = JSONField( blank=True, default=list) [ { "id": 1, "value": "31" }, { "id": 2, "value": "Hello" }, ... ] I need to get all objects where the id is 1 and value of that field is greater than 31. I have tried q = queryset.filter(values__0__id=1, values__0__value_gte=31) but it works only for objects if an object that I need located only in first element.
