How to run project with Gitlab CI registry variables?
Can you explain. I have Gitlab runner and now I am configuring CI/CD using one guide. It says that runner requires the image names in docker-compose.yml to be named like this: $CI_REGISTRY/organisation/path-to-project/project_image:$CI_ENVIRONMENT_SLUG-$CI_COMMIT_SHA I put this value in a variable in the .env file. But now when I run docker compose up - error pops up - says $CI_REGISTRY, $CI_ENVIRONMENT_SLUG and $CI_COMMIT_SHA are not set. What should I do in this case? Everything was working fine before CI/CD was connected. level=warning msg="The \"CI_REGISTRY\" variable is not set. Defaulting to a blank string." level=warning msg="The \"CI_ENVIRONMENT_SLUG\" variable is not set. Defaulting to a blank string." level=warning msg="The \"CI_COMMIT_SHA\" variable is not set.

jQuery ajax file upload not picking up updated file
Trying to upload a CSV file using HTML form and jQuery. Below are the steps to illustrate the issue 1.) Upload file for the first time, everything goes fine. 2.) Make changes to file and save it (say using MS Excel in this case) 3.) Select the file again and upload 4.) The old file is uploaded, changes made at step2 are not reflecting. 5.)

Problem parsing Django radio button when trying to set checked attribute
I need to build a set of radio buttons using Django. I've taken the approach of doing this in a template rather than a Django Form class as I was hoping it would give me more flexibility. I'm running into a problem when trying to conditionally add a checked attribut to preselect which radio is selected when the form loads. The code below works. It renders the 4 radio buttons and selects the last one. This is just a test obviously as this would always leave the last button selected. But it proves my model, view and template all work. {% for choice in thisSQwithQ.qid.GetChoices %} <input type="radio" name="choice" id="choice{{ forloop.counter }}" value="{{ choice.choiceid }}" checked="checked" > <label for="choice{{ forloop.counter }}">{{ choice.choice_text }}</label><br> {% endfor %} But, when I add the Django code to conditionally set checked="checked" for each radio, I'm getting a really odd syntax error. The following code gives me an error "Could not parse the remainder: '==' from 'selected_value=='" {% for choice in thisSQwithQ.qid.GetChoices %} <input type="radio" name="choice" id="choice{{ forloop.counter }}" value="{{ choice.choiceid }}" {% if selected_value== choice.choiceid %} checked="checked" {% endif %} > <label for="choice{{ forloop.counter }}">{{ choice.choice_text }}</label><br> {% endfor %} I've had a good … -
Django ModelMultipleChoiceField produces duplicate keys in rls params
I have a form in django with a ModelMultipleChoiceField, but when I submit the data, I have the same parameter repeated in the url for every selected option (like localhost:8000/search/?category=1&category=2). Here's a toy example: #forms.py class SearchForm(forms.ModelForm): category = forms.ModelMultipleChoiceField(Category.objects.all(), required=False) class Meta: model = Document fields = ("start_date", "end_date", "category") #views.py class SearchResultsView(ListView, FormView): model = Document template_name = "archive/document_list.html" context_object_name = "documents" form_class = SearchForm def get_queryset(self): object_list = Document.objects.all() if start_date := self.request.GET.get("start_date"): object_list = object_list.filter(date__gte=start_date) if end_date := self.request.GET.get("end_date"): object_list = object_list.filter(date__lte=end_date) if category := self.request.GET.get("category"): object_list = object_list.filter( category__name=category, ) return object_list.distinct() In the template: <form action="{% url 'search_results' %}" method="get"> <div class="flexline flex-wrap justify-content"> {{ form|materializecss }} <div> <button class="btn" type="submit">Submit</button> </div> </form> The form is displayed correctly: But when I click submit I get the following url: http://localhost:8000/search/?start_date=&end_date=&category=1&category=2 -
How do I allow requests from a frontend server to a django backend to not be prevented by CORS

How to express a One-To-Many relationship in Django without using foreignkey in class on the side many-relation?
I have a project to manage Assets in company. Asset is the core of project. I need to express One-To-Many relationship and Many-To-Many with Assets and the only way I know that: class List(models.Model): name = models.CharField(max_length=128) class Asset(models.Model): list = models.ForeignKey(List) I don't think that a good way because I have more classs like List in the project and if I do that, Asset will be have too much attributes are not necessary, when I have a new Asset I need to declare the attribute "list" - that impossible if that list doesn't exist (new list in future). Is there any way? Thanks for your help! -

Django Form with If function produce same result for every if combination
I'm still learning Django, and in this project of mine I try to create very simple quizz-like program that will recommend programming language based on user interest. So, There are 3 question, user only need to answer yes/no After the form is submitted, it'll be processed using if and recommendation will be produced according to user answer example: if user answer yes, yes, yes, my program will recommend "Javascript, HTML/CSS, React JS, Angular,Figma". if user answer yes, yes, no, my program will recommend "HTML/CSS, Javascript, Flutter" And the problem is, no matter what combination I use, my program will always return "Javascript, HTML/CSS, React JS, Angular, Figma"(first response in my if) Here is the detail of my code models.py from django.db import models # Create your models here. class User(models.Model): name = models.CharField(max_length=20) def __str__(self): return f"{self.name}" class Answer(models.Model): name = models.ForeignKey(User, on_delete=models.CASCADE) webdev = models.BooleanField(default=True) mobdev = models.BooleanField(default=True) uiux = models.BooleanField(default=True) def __str__(self): return f"{self.name.name}, {self.webdev}, {self.mobdev}, {self.uiux}" class Result(models.Model): name = models.ForeignKey(User, on_delete=models.CASCADE) response = models.CharField(max_length=50, default='Unidentified') def __str__(self): return f"{self.name.name} {self.response}" forms.py from django import forms class Quizzes(forms.Form): CHOICES = [ (True, 'Tertarik'), (False, 'Tidak Tertarik') ] name = forms.CharField(label='Siapakah nama anda?', max_length=20) wd = forms.ChoiceField( widget … -
Why is Google Chrome ignoring my cookie deletion request?
I am building a web application with Vue for the frontend running on localhost:5173 and using Django with DRF for the backend running on localhost:8000. I had no trouble writing the refresh token in the cookies for the login process. However, now I am trying to implement a logout feature which should delete the refresh token from the cookies, but for some reason it's not working - the cookie that was originally created during login doesn't get deleted and I'm not sure why. The cookie gets deleted just fine in Postman, but when I try to do it in a browser, it does not. Also, you can see in Chrome that the HTTP response header also is set to Set-Cookie: refresh_token=""; expires=Thu, 01 Jan 1970 00:00:00 GMT; Max-Age=0; Path=/ which I believe should signal to the browser to delete the cookie. It appears that the browser is ignoring that request. Any ideas why? In Django, during the login process, I am using the DRF function set_cookie to set the cookie using response.set_cookie(key='refresh_token', value=refresh_token, httponly=True) This works as expected. During the logout process, I am using the DRF function delete_cookie to delete the cookie, which isn't working. My Django views looks … -
Django-eventstream and Channels causes too slow page load
I have django project that users send notifications to my custom admin dashboard, i am using django-channels 3.0.5 and django-eventstream for it. Everything is okay, users can send notifications to my admin dashboard but sometimes when i want to change page, for example i am in contacts page and i want to any other page, page stucks at loading about one minute. Then loads all content with no error. everything is okay again. I think it's because django-channels, when i disable channels in asgi.py all pages loading fast. Here is my code: contact form views.py (it sends notification to me). everything is okay here def contact(request): if request.method == "POST": form = ContactForm(request.POST) if form.is_valid(): user_profile = UserProfile.objects.get(user=request.user) contact_message = form.save(commit=False) contact_message.user_profile = user_profile contact_message.save() messages.success(request, "Mesajınız göndərildi") send_event('contact', 'message', {'text': 'hello world'}) else: form = ContactForm() context = { 'form': form, } return render(request, 'site/contact/contact.html', context) asgi.py os.environ.setdefault("DJANGO_SETTINGS_MODULE", "project.settings") application = ProtocolTypeRouter({ 'http': URLRouter([ path('contact-events/', AuthMiddlewareStack( URLRouter(django_eventstream.routing.urlpatterns) ), { 'channels': ['contact'] }), path('security-events/', AuthMiddlewareStack( URLRouter(django_eventstream.routing.urlpatterns) ), { 'channels': ['securitycalls'] }), re_path(r'', get_asgi_application()), ]), }) -
Replace data from server with data from local storage if it exists - Django
I know this might seem like a very basic question but I am still a beginner and trying to figure this out. I have created a webpage containing a form in Django. Right now the form comes prefilled with a few values and the user has to fill in the rest. It has different sections like education, work experience, basic info, etc and the user can add or delete multiple sections in education. The form data is ultimately stored in a JSON. Right now every time a user clicks on add or delete the data manipulation happens in the frontend but just so that the changes reflect in the page I have to send it to the backend and reload the page. FRONT END DISPLAY FORM CODE: <h2>Technical Skills</h2> {% for item in resume.techskill %} <fieldset> <div class="tech"></div> <legend>Technical Skill {{ forloop.counter }}</legend> <label for="skillName{{ forloop.counter }}">Skill Name:</label> <input type="text" id="skillName{{ forloop.counter }}" name="skillName{{ forloop.counter }}" value="{{ item.skill_name }}"><br><br> <label for="expertise{{ forloop.counter }}">Expertise:</label> <input type="text" id="expertise{{ forloop.counter }}" name="expertise{{ forloop.counter }}" value="{{ item.expertise }}"><br><br> <label for="yearOfExp{{ forloop.counter }}">Year of Experience:</label> <input type="text" id="yearOfExp{{ forloop.counter }}" name="yearOfExp{{ forloop.counter }}" value="{{ item.year_of_exp }}"><br><br> <button type="button" onclick="deleteTechSkill('{{forloop.counter}}')">Delete Technical Skill</button><br><br> </fieldset> {% endfor %} … -
In Django Rest Framework (DRF) how to do pagination when we are getting page number from request body?

Clean method and validation of individual fields
I have a model with some fields with blank=False. I have a form: class FipiForm(ModelForm): def _validate_ready_for_whole_exam(self, cleaned_data): ... def _validate_modify_spoilt_task(self, cleaned_data): ... def _validate_correspondene_of_modification_to_task(self, cleaned_data): ... def clean(self): cleaned_data = super().clean() # Breakpoint self._validate_ready_for_whole_exam(cleaned_data) self._validate_modify_spoilt_task(cleaned_data) self._validate_and_modify_spoilt_task(cleaned_data) self._validate_and_modify_spoilt_task(cleaned_data) self._validate_correspondene_of_modification_to_task(cleaned_data) return cleaned_data class Meta: model = FipiTask exclude = [] I intentionally left some fields empty. Well, form is not valid. What I'd like to have is delegate validation of fields to Django. And in clean method I would like to validate interdependence between fields. In other words I thought that if method super().clean() has been called, blank=False has already been validated. But I was wrong. Could you tell me what to do: either validate individual fields here, in "clean" method? But that looks contrary to the idea of the framework. -
