Django: how to set value to not displayed form field? 'WSGIRequest' object has no attribute 'seller'
I can not solve my issue. I need help, it will be really kind :) channel and consumer are automatically set thanks to the view "form.instance". But I don't know how to do the same with seller. Important, the page is dedicated to two user: seller and consumer. Only consumer can give a review. The page is a channel. So what's the best way to set automatically seller value? class Channel(models.Model): consumer = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name="channel_consumer", blank=True, null=True) name = models.CharField(max_length=10) seller = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name="channel_seller") class Rating(models.Model): channel = models.OneToOneField(Channel,on_delete=models.CASCADE,related_name="rating_channel") consumer = models.ForeignKey(settings.AUTH_USER_MODEL, blank=True, null=True, on_delete=models.CASCADE,related_name='rating_consumer') seller = models.ForeignKey(settings.AUTH_USER_MODEL, blank=True, null=True, on_delete=models.CASCADE,related_name='rating_seller') is_rated = models.BooleanField('Already rated', default=True) comment = models.TextField(max_length=200) publishing_date = models.DateTimeField(auto_now_add=True) ratesugar = models.IntegerField(validators=[MinValueValidator(1), MaxValueValidator(5)]) def __str__(self): return self.channel.name views.py ... def form_valid(self, form): if form.is_valid(): form.instance.channel = self.object form.instance.seller = self.request.seller.userprofile.pk form.instance.consumer = self.request.user form.save() return super(ChannelReview, self).form_valid(form) else: return super(ChannelReview, self).form_invalid(form) forms.py class ChannelRatingForm(forms.ModelForm): def __init__(self,*args,**kwargs): super(ChannelRatingForm, self).__init__(*args,**kwargs) self.helper = FormHelper() self.helper.form_method="post" self.helper.layout = Layout( Field("comment",css_class="form-control",style="margin-bottom:10px",rows="1"), Field("ratesugar",css_class="single-input"), ) self.helper.add_input(Submit('submit','Review',css_class="btn btn-primary single-input textinput textInput form-control")) class Meta: model = Rating widgets = { 'comment':forms.TextInput(attrs={'class':'','style':'','placeholder':'What a cook!'}), } fields = [ 'comment', 'ratesugar', ] -
Python Script Nor Running In PythonAnywhere
I am working on a Django project. It includes a functionality in which when admin clicks on a certain button, it runs a Python script and redirect it to some other page after complete process. Before hosting, it was working fine. Now that I hosted it here, the script doesn't run at all. It just redirects to another page without providing any error. Why's that? Also, my script includes chromedriver, in case it has anything to do with it. Kindly help me. This might be the error. Why doesn't it recognize it? Code out = run([sys.executable, '//home//maisum279//traffic//traffic//trafficapp//traffic.py', "--domain", url, "--threads", '5', "--max-clicks", maximum, "--min-clicks", minimum, "--stay", stay, "--requests", requests]) Server Log 2020-09-21 11:05:02 /usr/local/bin/uwsgi: unrecognized option '--domain' 2020-09-21 11:05:02 getopt_long() error The script is in Python, but now it seems to be running with uswgi. What can I do make it work? Please help. -

Django upload image using page slud/id
I'm trying to add the ability to upload an image to a post but having issues. The image field is in its own model but uses a foreign key to show which post it relates to.

Returning optimised queryset based off of request.user for private comments
I currently have a comments model, whereby users can submit comments to our system "privately". This is set as a Boolean field on the model level, abridged version of the model as follows: class Comment(AbstractUUIDModel, AbstractTimestampedModel, VoteModel): class Meta: db_table = 'comments.Comment' indexes = [ models.Index(fields=['uuid', 'id']), ] verbose_name = 'Comment' verbose_name_plural = 'Comments' ordering = ['-created_datetime'] id = models.AutoField(_('ID'), primary_key=True) parent = models.ForeignKey('comments.Comment', null=True, blank=True, on_delete=models.CASCADE) owner = models.ForeignKey('authentication.User', null=True, on_delete=models.CASCADE) text = models.TextField(_('Description'), default='') private = models.BooleanField(_('Is Private?'), default=False) def __str__(self): return self.text def save(self, *args, **kwargs): super(Comment, self).save(*args, **kwargs) Essentially, the conceptual issue I am having is around my queryset filter logic. I want it such that if the request.user coming in to the system is the owner of the comment, then they can see their own "private" comments. Else, they can only see the comments where private is false. So, I need to somehow merge the following two querysets for serialization in DRF: queryset = obj.comment_set.filter(private=False) queryset = obj.comment_set.filter(owner=self.context.get('request').user) I believe I am overthinking this, and perhaps I can do something like: from django.db.models import Q queryset = obj.comment_set.filter( Q(owner=self.context.get('request').user) | Q(private=False) ) Using Q objects... -

How use Relative Url in html in Django?
Creating Django application , In Navbar there 3 anchor tags. When I write direct href="user/register" in Html file, it works for only first click. Getting url like http://127.0.0.1:8000/user/register/ from here if I click on any navbar link url is getting like http://127.0.0.1:8000/user/register/user/register or http://127.0.0.1:8000/user/register/login Have a look to code ProjectFolder/urls.py from django.contrib import admin from django.urls import path, include from . import views urlpatterns = [ path('admin/', admin.site.urls), path('', views.homePage, name = "homepage"), path('uploadFiles/', include("uploadFiles.urls")), path('user/', include("login.urls")), ] AppFolder.py/urls.py from django.urls import path from . import views urlpatterns = [ path("register/", views.register, name = "register") ] AppFolder/Views.py from django.http import HttpResponse from django.shortcuts import render # Create your views here. def register(request): if request.method == "POST": return HttpResponse("Working on database") else: return render(request, "login/Register.html") Navbar.html <div class="collapse navbar-collapse" id="navbarsExampleDefault"> <ul class="navbar-nav mr-auto"> <li class="nav-item active"> <a class="nav-link" href="/">Home <span class="sr-only">(current)</span></a> </li> <li class="nav-item active"> <a class="nav-link" href="user/register">Register</a> </li> <li class="nav-item active"> <a class="nav-link" href="login">Log In <span class="sr-only">(current)</span></a> </li> </ul> </div> -

Integrating AWS Lambda with Django Signals and Postgresql RDS
I am wondering if I could trigger an AWS Lambda function using Django's post_save signal, or trigger an AWS Lambda function when a model is saved (just as Django's post_save signal does). Additionally, I would like to know some conventional ways of accessing and making changes to postgresql RDS in AWS Lambda functions. Any tips or suggestions will be greatly appreciated. Thank you!
