How to implement tooltip with django form
I have a model form based on this model: class MyModel(TimeStampedModel): MY_CHOICES = [tuple([x,x]) for x in range(1,8)] p1 = models.IntegerField("P1”, default='1', help_text=‘text1’) p2 = models.IntegerField(“P2”, default=‘1’, , help_text=‘text2’) Parent = models.ForeignKey(ParentModel, on_delete=models.CASCADE) The form itself looks like: class MyModelForm(ModelForm): def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.helper = FormHelper(self) self.helper.form_id = 'id-CaseForm' self.helper.form_class = 'blueForms' self.helper.form_method = 'post' self.helper.form_tag = False self.helper.help_text_inline = False self.helper.form_show_labels = False self.helper.layout = Layout( Row(Field(PrependedText('p1', ‘field_label1’, wrapper_class='col-12 col-lg-6 pe-0 stretchprepend'))), Row(Field(PrependedText('p2’, ‘field_label2’, wrapper_class='col-12 col-lg-6 pe-0 stretchprepend’)))) CHOICES = [tuple([x,x]) for x in range(1,8)] p1 = IntegerField( label='field_label1', widget=Select(choices=CHOICES)) p2 = IntegerField( label='field_label2’, widget=Select(choices=CHOICES)) class Meta: model = MyModel fields = ['p1', 'p2’,] And this is displayed as a crispy form in the template: {% crispy panss_form %} I want the user to see some help text when they hover over the fields. This help text could be the help_text from the model, or I am happy to put it somewhere else (although it should go in either the model or the form, not in the template). Any help appreciated. -

Django - Display the number of users currently watching a live stream
I'm developing a Django site for a sports streaming service. It is necessary to display the number of users who are currently watching the broadcast. You can watch the broadcast only after authorization. What is the best way to implement this? At the moment I think that the best solution would be to send a js request to the Django server, but I think there is a better way. -

Enviroment Variables are not loading into Pytest with ini file

You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

Django profiles for multiple user types
I am new to Django. My application has three user types who are mutually exclusive.They can be identified using a choice field. Want to understand how to create different user profiles for different user types as each profile will have different properties. Let's say the user types are customer, employee and partner.After googling so many days, Only way I found was to inherit User/Abstract User model and have three different apps for each user type. That's there are will be login page, register page like wise for each user type. I thought I could at least have one app to handle user login and based on the user type from the choice field, to attached the correct user profile. Is this something that can be done. Second I want to provide the correct profile to the user when registering. Is this possible. Thank you in advance. I stated before I tried to have three apps. -
Sending data from Python to HTML in Django
I have a Django project with a form in an HTML file, and I'd like to update the text on the submit button of that form WITHOUT a page reload. Essentially: I click submit on the form Python handles the submit with the form data The button text is updated to say "show result" If I understand correctly, I have to use AJAX for this. The problem is that the form submit relies on an API call in Python, so the HTML essentially has to always be "listening" for new data broadcasted by the views.py file. Here's the code I have (which doesn't work): views.py: def home(request): if request.method == "POST": print("Got form type", request.content_type) return JsonResponse({"text": "show result"}) return render(request, 'home.html') home.html: (form code) <button id="submit" type="submit">Submit</button> (end form) <script type="text/javascript"> function queryData() { $.ajax({ url: "/", type: "POST", data: { name: "text", 'csrfmiddlewaretoken': '{{ csrf_token }}', }, success: function(data) { var text = data['text']; var button = document.getElementById('submit'); button.innerHTML = text; setTimeout(function(){queryData();}, 1000); } }); } $document.ready(function() { queryData(); }); </script> I've imported jQuery with the script <script src="https://ajax.aspnetcdn.com/ajax/jquery/jquery-1.9.0.min.js"></script>. Any idea why this doesn't work in its current state? Thanks! -
Debug the React part of a hybrid React+Webpack+Django in VS Code
I have a hybrid Django + React application: the React frontend is built using Webpack, added to the static files and included in a Django template page (this is based on this tutorial Modern Javascript for Django Developers).

Is it ok to have two or more Django forms in one HTML form?
I know it's possible to have more than one Django form in one HTML form, even formsets, and standard forms combined and it works perfectly fine. I want to know if it is a good practice and how this can impact security if it will at all? I couldn't find any information about those cases but in tutorials, I saw both (multiple Django forms in one HTML and every Django form in a separate HTML form) in some cases is necessary since the two forms can do different things like update and delete for example. In my case, all forms POST data to different models, and then all are combined in one model. Please take a look at the example (This is a simple example and not the actual code) below: <form action="" method="POST"> {% csrf_token %} {{ form.field1 }} {{ form.field2 }} {{ form.field3 }} {% for field in dates_form %} {{ field.Loading_date_from }}{{ field.Loading_time_from }}{{ field.Loading_date_to }}{{ field.Loading_time_to }} {% endfor %} {% for field in dates_form2 %} {{ field.Loading_date_from }}{{ field.Loading_time_from }}{{ field.Loading_date_to }}{{ field.Loading_time_to }} {% endfor %} {{ form.field4 }} {{ form.field5 }} <input type="submit"> </form> -
Why is it industry standard to run JS frameworks like Vue.js and React with conjuction of Node.js? [duplicate]
I have seen number of existing projects: where frontend is served from node.js server. backend server (non node.js) is providing some REST API. Clients communicate with this server the rest of the time. So nodejs is needed just for initial request. I see that frontend nodejs server does not much, but provides some static resources and js dependencies. Having frontend provided by django or even by nginx (if no server side rendering required) seems more simple. It feels like an overkill to have an extra nodejs server in your environment. We don't need to maintain extra node.js server. What am i missing here? What advantage gives this frontend node.js server? -
How do I override a template-tag for the "pinax" application in Django?
Unfortunately for me, the "pinax" application for Django does not seem to have stayed up with the times – in one specific way: the shorttimesince template-tag still refers to the tzinfo object which has been deprecated. The message is this: django.template.library.InvalidTemplateLibrary: Invalid template library specified. ImportError raised when trying to load 'pinax.templatetags.templatetags.shorttimesince_tag': No module named 'django.utils.tzinfo' In my project, I have a overrides/pinax/templatetags directory which contains both __init__.py and shorttimesince_tag.py which contains the updated code. But it does not seem to be referenced. Whereas, the same project contains an overrides/pinax/notifications/backends/email.py which, so far as I know now, is being correctly referenced and which still appears to work. The 'TEMPLATES:DIRS' settings do now contain: os.path.join(os.path.dirname(os.path.realpath(__file__)), 'templates', 'overrides/pinax'), ... which is what I assume causes the other override to be recognized. But apparently the "templatetag" override is not being seen. -

Dynamically using select2 in django formset
I am able to add multiple forms successfully with formset. I am using select2 in the product name part of the form. But as I mentioned below, I manually enter the form ids. $(document).ready(function() { $('#id_store_house_id').select2(); $('#id_product_id').select2(); etc.. }); But it doesn't work because the form id changes dynamically every time I add a new form. I am bad at javascript. I have tried similar threads and solutions on stackoverflow but without success. my form and java script like this : form : <div class="row"> <div class="col-md-6 offset-md-3"> <h3 align="center">Add New Task</h3> <hr> <form id="form-container" method="POST"> {% csrf_token %} {{user_task_form | crispy }} {{ formset.management_form }} {% for form in formset %} <div class="tasksources-form"> {{form | crispy}} </div> {% endfor %} <button id="add-form" class="btn btn-success">+Add More Product</button> <br> <br> <button type="submit" class="btn btn-outline-info">Add New Task</button> </form> </div> </div> my js : <script> let tasksourcesForm = document.querySelectorAll(".tasksources-form") let container = document.querySelector("#form-container") let addButton = document.querySelector("#add-form") let totalForms = document.querySelector("#id_form-TOTAL_FORMS") let formNum = tasksourcesForm.length-1 addButton.addEventListener('click', addForm) function addForm(e){ e.preventDefault() let newForm = tasksourcesForm[0].cloneNode(true) let formRegex = RegExp(`form-(\\d){1}-`,'g') formNum++ newForm.innerHTML = newForm.innerHTML.replace(formRegex, `form-${formNum}-`) container.insertBefore(newForm, addButton) totalForms.setAttribute('value', `${formNum+1}`) } </script> Thanks for your help.

Why when I try to search for a product, nothing comes up?
I've created an ecommerce website using Django, though the search results aren't coming up when I try to search for a product. For example, when I try to search for part of a product title, like throat spray, nothing comes up even though there is a throat spray in the database. I tried using the Post and Get methods though it didn't really make any difference between the two. I checked to make sure the url for the show_product page works and it does. I'm expecting search results for what I searched for. Though, the search page goes through, nothing comes up as the search results. Instead I get a /search/?searched=throat-spray My views.py: def search(request): if 'searched' in request.GET: searched = request.GET['searched'] products = Product.objects.filter(title__icontains=searched) return render(request, 'epharmacyweb/search.html', {'searched': searched, 'product': products}) My search.html: <center> {% if searched %} <h1>Search Results for {{ searched }}</h1> <br> {% for product in products %} <a href="{% url 'epharmacyweb/show-product' product.title %}">{{ product }}</a> {% endfor %} </br> {% else %} <h1>You haven't searched anything yet...</h1> {% endif %} </center> My urls.py: path('search/', views.search, name='search'), path('search-error/', views.search_error, name='search_error'), path('show-product/', views.show_product, name='show-product'), My show_product.html: <div class="col"> <div class="card shadow-sm"> <img class="img-fluid" alt="Responsive image" src="{{ product.image.url … -
Django prevent duplication of two foreign keys in one model
I have two foreign key fields that point to the same model. I would like to prevent them from having the same value. Here is my code that does not work class Match(models.Model): team_a = models.ForeignKey(Team, related_name='team_a', on_delete=models.CASCADE) team_b = models.ForeignKey(Team, related_name='team_b', on_delete=models.CASCADE) match_date_time = models.DateTimeField(validators=[validate_matchdate]) winner = models.CharField(choices=CHOICES, max_length=50, blank=True, null=True) def clean(self): direct = Match.objects.filter(team_a = self.team_a, team_b=self.team_b) reverse = Match.objects.filter(team_a = self.team_b, team_b=self.team_a) if direct.exists() & reverse.exists(): raise ValidationError('A team cannot be against itself')
