Django HTML for loop with filter
In my django project, I have an HTML that renders questions header, and inside the question headers I have question items. In my model, Question headers and items are two different entities. I need to show for every header, just the items related to that header. As it shows all items for all questions without any filters. Greatly appreciate any help! Model: class Question(models.Model): question = models.CharField(max_length=240) mission_section = models.ForeignKey('Mission_Section', on_delete=models.CASCADE) type_question = models.ForeignKey('Type_Question', on_delete=models.CASCADE) categories_question = models.ForeignKey('Categories_Question', on_delete=models.CASCADE, default=1) order = models.IntegerField(default=1) def __str__(self): return self.question class Question_Option(models.Model): question = models.ForeignKey('Question', on_delete=models.CASCADE,default=1) option = models.CharField(max_length=240) correct = models.BooleanField() order = models.IntegerField(default=1) View: class Questions(LoginRequiredMixin, FormView): template_name = "questions.tmpl" def get(self, request, pk): context = { 'pk': pk, 'section': Mission_Section.objects.get(pk = pk ), 'questions_items': Question_Option.objects.filter(question__mission_section__pk=pk).order_by('order','pk'), 'questions': Question.objects.filter(mission_section__pk = pk ), 'question_types' : Type_Question.objects.all(), 'questions_categories': Categories_Question.objects.all()} return render(self.request, self.template_name, context) HTML <input type="hidden" class="form-control" id="section" name="section" value="{{section.id}}" required> <h1>{{ section.name }}</h1> <div id="contentDiv"> <ol> {% for question in questions %} <div name="question" class="form-group" id="question-{{question.id}}" > <form class='my-ajax-form' id="form-question-{{question.id}}" method='GET' action='.' data-url='{{ request.build_absolute_uri|safe }}'> <li><div class="input-group"> {% csrf_token %} {{ form.as_p }} <input type="text" value= "{{question.id}}" id="question" name="question-hidden" class="form-control"> <input type="text" value= "{{question.question}}" id="question_name_{{question.id}}" class="form-control" aria-label="Amount" onchange="UpdateQuestion({{question.id}})"> </div> </form> <br> <!-- Options … -
JSON vs. Tables in PostgreSQL
I am trying to make a questionnaire and am considering 2 data structures: JSON: I could use JSON to store the different questions as follows: { "questions": [ { "question": "how old are you?", "type": "input_int", }, "question": "what is your name", "type": "input_string", }, { "question": "how are you today?", "type": "multiple_choice", "options": [ "good", "bad" ] }, ] } Or a table for each type of question: InputIntTable - Question - Order InputStringTable - Question - Order MultipleChoiceTable - Question - Options - Order I am using Django. Which way would be better both computationally, structurally, and cost wise to host. Which would take more storage? Thanks!! -
User model inherit AbstractBaseUser but still get AttributeError: 'User' object has no attribute 'check_passsword'?

Dynamically Switch Database In Django App running inside docker container using environment variable
Problem: I want to switch the Django database after changing environment variables during run time Django app settings.py file PG_DB_USER = os.environ.get('PG_DB_USER', '') PG_DB_NAME = os.environ.get('PG_DB_NAME', '') PG_DB_PASS = os.environ.get('PG_DB_PASS', '') PG_DB_HOST = os.environ.get('PG_DB_HOST', '') PG_DB_PORT = os.environ.get('PG_DB_PORT', '') DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql_psycopg2', 'NAME': PG_DB_NAME, 'USER': PG_DB_USER, 'PASSWORD': PG_DB_PASS, 'HOST': PG_DB_HOST, 'PORT': PG_DB_PORT, } } There is a docker-compose.yml file where different services are listed along with the respective environment variable.

How to implement something similar to list_display on generic list view?
I was trying to create a generic list template which would render all defined fields I wanted, just like the list_display from django admin.. I tried obj.values and obj.values_list, along with the specific fields, but these are not suitable when rendering choice fields since they bring a dict and a querysetdict and the get_foo_display is not available.. A managed=False also won't help since there is a filter of a field that can't be shown as well.. the .only() method also did not help because it does not 'cut' the fields from the obj.. I tried to copy the logic behind django admin list_display, but am I missing something in the generic list view? -

Password not set for new django users
When a new user signs up for an account, the admin panel shows that a password has not been set for the user (despite saving it via views.py).

Django admin - make image appear over the django admin list view
Following up on a question from Django Admin - display image on hover. I'm able to make the image appear on hover like I was hoping. However, if the django admin list view only has a few items in it, part of the image appears behind the bottom of the list Here's an example of what it looks like, with some column headers greyed out The image extends beneath the bottom of the list (as hinted at by the appearance of the scroll bar). We'd like it to pop over the top, so the full image is visible regardless of the length of the list Here's the code we have def image_column(self, object) return format_html(text+" "+\ '''<a href="{}"" target="_blank" style="font-size: 18pt; position: relative;" onmouseover="document.getElementById('{}').style.display='block'; position: relative;" onmouseout="document.getElementById('{}').style.display='none';"><div style="position:relative">📷</div> <img id="{}" style="display:none; position: absolute; top: 0px; left: 0px; width:550px; border:5px solid; z-index:1000;" src="{}" /> </a>'''.format( url, img_id, img_id, img_id, url)) I've tried setting the position:absolute in the image tag to position:relative. This makes sure the whole image is displayed when you mouse over (expanding the containing row). However, it affects the the layout of the rest of the document, which is disorienting the user Thank you!!! -

Django 'holding page' and redirect for background processes
I have a form (IngestFormView), which on submission kicks off multiple background processes (dealing with files uploaded in the form). I also have an API view (IngestStatusView) which shows the status of the various background processes. Finally, I have a second form (IngestCompletionFormView) which is dynamic, based on the results from the various background processes I need users to be redirected to IngestCompletionFormView, but not until the aforementioned processes have concluded. I am really quite new to JavaScript, but I know I need to do something with AJAX/JQuery to show the user the, regularly updated, status from IngestStatusView, before redirecting the user to IngestCompletionFormView. Does anyone have any recommendations for how to achieve this? I don't think I can do anything on IngestFormView as I need that to deal with form errors, so adapting it could become complex. So I had wondered if I should created a separate view to sit between the two form views. This view will then use AJAX/JQuery to call IngestStatusView and update the user on progress. Then, based on a field in IngestStatusView, it would identify that all background tasks have concluded, and redirect to IngestCompletionFormView. Thank you for any thoughts. -

Does LiClipse admit Django Templates?
I am new to Django/Python and LiClipse (Django 3, Python 3.8, Liclipse 6.1.0), and when writing the html templates, I find that the Django blocks seem to interfere with the html correction. For instance, this code in base.html: <!DOCTYPE html> <html lang="en-US"> <head> <meta charset="UTF-8"> <meta http-equiv="X-UA-Compatible" content="IE=Edge"> <meta content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no" name="viewport"> <meta name="generator" content="Bootply" /> <title>Report</title> <title>Este es un título</title> </head> <body> <h4>Home page de prueba de cjg</h4> </body> </html> Everything is fine, but if I add {% load static %} <!-- CSS --> {% block css %} {% endblock %} <!-- JAVASCRIPT --> {% block js %} {% endblock %} right after the title I get errors like Stray end tag “head”. for /head and An “body” start tag seen but an element of the same type was already open. Seems that the editor won't recognize django blocks. Is there any configuration I should make or some plugin I should add?. Thanks in advance for your help. -

I then want to implement a "load more" button to display another 10 blogposts and so on and so forth until all 100 are displayed. So my basic idea is that I fetch all 100 in the view and then populate the DOM using jQuery on each "load more" click. How can I accomplish this? Do I need Ajax calls to trigger a view for each button click? And how to handle the DOM since it is populated with Django variables. I guess I somehow have to re-trigger the for-in / end-for Django loop to make the new posts append and not overwrite the existing DOM? From a tutorial I tried to approach a paginator solution but I don't know how to link this to jQuery/make the magic on the frontend. blog.views def render_blog(request, template="blog.html"): category_count = get_category_count() # Display last 10 blog posts on landing page, make pagination in 10x steps via button click most_recent = Post.objects.order_by('-timestamp')[:99] post_list = Post.objects.all() paginator = Paginator(post_list, 10) page_request_var = 'page' page = request.GET.get(page_request_var) try: paginated_queryset = paginator.page(page) except … -

How to update the django model after useing filter or order_by?
I wanna make a website that users can update the information. here is part of my website But I have a problem here, the update only works when it is in the normal order, it won't work when I order by price or order by rank or after I filter by some choice (e.g Dell, N2840). Here is my code view.py. if request.method == 'POST' and 'update_bt' in request.POST: i = 0 asin = [] alldata = Output.objects.all() for i in alldata: asin.append(i.asin) while i < len(request.POST.getlist('brand')): Output.objects.filter(asin = asin[i]).update(List = request.POST.getlist('list')[i]) Output.objects.filter(asin = asin[i]).update(brand = request.POST.getlist('brand')[i]) Output.objects.filter(asin = asin[i]).update(cpu = request.POST.getlist('cpu')[i]) Output.objects.filter(asin = asin[i]).update(screen = request.POST.getlist('screen')[i]) Output.objects.filter(asin = asin[i]).update(ram = request.POST.getlist('ram')[i]) Output.objects.filter(asin = asin[i]).update(Type = request.POST.getlist('type')[i]) Output.objects.filter(asin = asin[i]).update(model = request.POST.getlist('model')[i]) Output.objects.filter(asin = asin[i]).update(os = request.POST.getlist('os')[i]) Output.objects.filter(asin = asin[i]).update(DVD = request.POST.getlist('DVD')[i]) Output.objects.filter(asin = asin[i]).update(keyboard = request.POST.getlist('keyboard')[i]) Output.objects.filter(asin = asin[i]).update(security = request.POST.getlist('security')[i]) Output.objects.filter(asin = asin[i]).update(vc = request.POST.getlist('vc')[i]) i += 1 alldata = Output.objects.all() return render(request, 'polls/base.html', {'alldata': alldata}) I understand why it only works in this way, but I just don't know how to make it work in every possible situation. I am new to Django. Does anyone know how to make it work? Thank you.
