What is the best way to create a 'list' associated with a model?
I want to be able to associate a company name in my models with a list of 'milestone' percentage points, in order to calculate how far each company is from the nearest milestone. For example: List_Of_Milestones = [5, 10, 15, 20, 25] Current_Progress = 9.5% Example Output = "Company A is 0.5% away from the 10% milestone, and 4.5% above the 5% milestone." The logic is simple from a Python standpoint, but I can't get my brain around how I would create this in a model setup and allow the user to set their own list of milestones. -

Myself Dhinesh. But I'm a beginner at Django Rest Framework. Here, I'm trying to change the lookup_field from pk to a custom field (IP_Address). But I'm getting this error again and again.

Using Jinga2 Loop Control extension
I would like to break out of a for loop in a template. I understand this is not possible in DTL, but according to the docs it is possible if using Jinja2 (with the Loop Control extension) as the template engine. So I have updated my settings.py to include { 'BACKEND': 'django.template.backends.jinja2.Jinja2', 'DIRS': [os.path.join(BASE_DIR, 'templates/jinja2')], 'APP_DIRS': True, 'OPTIONS': { 'environment': 'project4.jinja2.environment'}, }, I define the Jinja environment in jinja2.py: from jinja2 import Environment from django.contrib.staticfiles.storage import staticfiles_storage from django.urls import reverse def environment(**options): env = Environment(**options, extensions=['jinja2.ext.loopcontrols']) env.globals.update({ 'static': staticfiles_storage.url, 'url': reverse, }) return env In my views.py is point to the jinja template file: return render(request, "jinja2/index.html", { "pages": page_obj, "liked": liked_posts }) But when I try to use the break statement in my loop like so: {% for like in liked %} {% if like.liked_post == page %} <span><button class="btn btn-secondary" id="unlike">Unlike</button></span> {% break %} {% else %} <span><button class="btn btn-secondary" id="unlike">Like</button></span> {% endif %} {% endfor %} I receive the following error: Invalid block tag on line 30: 'break', expected 'elif', 'else' or 'endif'. Did you forget to register or load this tag? What am I missing? Should the Jinja2 environment be be created in my views.py? -

How do i build a web application with django? [closed]
Okay so i am meant to build an online consultation app for my project in school and ive done some small apps over time with Django but i dont know the first thing on how to create a full stack web application. I dont really have that much time to the deadline so i just want to ask. If i were to start learning now to start creating a full stack app, which way do you think i should go about learning it. option1 (learn how to combine javascript and bootstrap with django without the use of rest framework), option2(django and rest framework with javascript and bootstrap), option 3(learning django and React without the use of rest_ framework) and option 4(learning django, react and rest_framework). I really just want to know which way would be faster and easier to learn and create my app with. Keep in mind that django is the only constant option because that is the only language i am familiar with. if there are any other easier and better ways or languages to learn other than django then pls suggest. Thank you. -
Django admin site: Unable to lookup 'child model' on 'parent model or 'parent modelAdmin'
This one's really difficult to write as a question since I'm not exactly sure how to ask this in the first place. But I'll try. Basically, I'm experiencing an AttributeError when I'm visiting the parent model in my django admin site. My current django database has 2 tables (except the prebuilt tables): a parent table / model for activity, and a child table / model for instruction. This is the structure of my models: class activity(models.Model): title = models.CharField(max_length=30,default=None) date_created = models.DateTimeField(auto_now_add=True) date_updated = models.DateTimeField(auto_now=True) author = models.ForeignKey(User,on_delete=models.CASCADE,default=None) def __str__(self): return self.__class__.__name__ class instruction(models.Model): detail = models.CharField(max_length=50,default=None) date_created = models.DateTimeField(auto_now_add=True) date_updated = models.DateTimeField(auto_now=True) author = models.ForeignKey(User,on_delete=models.CASCADE,default=None) activity = models.ForeignKey(activity,on_delete=models.CASCADE,default=None) def __str__(self): return self.__class__.__name__ So, if I add a new activity in the django admin site, say: Push-ups, then, I should be able to select this newly added parent record in the instruction form. However, when I try to add a new instruction record and select a saved activity record, the activity dropdown shows the name of the model only(in this case, activity). It doesn't show Push-ups. What I did next was to add some modelAdmins for the activity and instruction. Here's the code: class activityAdmin(admin.ModelAdmin): list_display = [field.name for field … -

However, the move forward button on the page that supposed to move the tire doesn't work as it supposed to. the web interface and the post request sent from the forward button The project works fine before it arrive to me and move as it supposed to. Here some things I've discovered while troubleshooting: The project auto detect the changes of IP address which means connected to another different wifi would not be the problem. I believe there's also no problem with the connection of the page and the project since I already try edit something in the project file in the raspberry pi and it appears on the web page on my computer.

I got the following error message: Traceback (most recent call last): File "functional_tests.py", line 3, in <module> browser.get('http://localhost:8000') File "/Users/kiyeonj/opt/anaconda3/envs/tdd_practice/lib/python3.8/site-packages/selenium/webdriver/remote/webdriver.py", line 333, in get self.execute(Command.GET, {'url': url}) File "/Users/kiyeonj/opt/anaconda3/envs/tdd_practice/lib/python3.8/site-packages/selenium/webdriver/remote/webdriver.py", line 321, in execute self.error_handler.check_response(response) File "/Users/kiyeonj/opt/anaconda3/envs/tdd_practice/lib/python3.8/site-packages/selenium/webdriver/remote/errorhandler.py", line 242, in check_response raise exception_class(message, screen, stacktrace) selenium.common.exceptions.WebDriverException: Message: Reached error page: about:neterror?e=connectionFailure&u=http%3A//localhost%3A8000/&c=UTF-8&d=Firefox%20can%E2%80%99t%20establish%20a%20connection%20to%20the%20server%20at%20localhost%3A8000.

Django doesn't raise ValidationError on ModelChoiceField (widget RadioSelect) if user didn't select any choice
I have a form that contains a ModelChoiceField poller_category class PollersForm(forms.Form): # Poller Category poller_category = forms.ModelChoiceField(widget=forms.RadioSelect(attrs={ 'class': 'poller-category-radio', }), queryset=Categories.objects.all().order_by('poller_category'), label='Select a Category') which is rendered as follows: <!-- Poller Categories --> <div class="fieldWrapper"> <div class="label">{{ form.poller_category.label_tag }}</div> <div class="category-ctn"> {% for category in form.poller_category %} <div class="category-wrapper">{{ category }}</div> {% endfor %} </div> </div> Now if the user doesn't select any category and tries to submit the form, nothing just happens. That actually means that the form is valid, doesn't it? If so, why doesn't it trigger the redirect? Also If I select a choice and submit, redirect is called, but the category isn't populated in the DB. # create a form instance and populate it with data from the request: form = PollersForm(request.POST) # check whether it's valid: if form.is_valid(): # process the remaining data in form.cleaned_data as required poller_text = form.cleaned_data['poller_text'] poller_category = form.cleaned_data['poller_category'] poller_choice_one = form.cleaned_data['poller_choice_one'] poller_choice_two = form.cleaned_data['poller_choice_two'] # Get the user created_by = request.user # Save the poller to the database p = Pollers(poller_text=poller_text, poller_choice_one=poller_choice_one, poller_choice_two=poller_choice_two, poller_category=poller_category, created_by=created_by) p.save() # redirect to a new URL: return redirect(poller_success) # if a GET (or any other method) we'll create a blank form else: form = … -
