How can I mark button as active based on the page I am at?
when a user clicks a tab I want that tab to show as active in blue. I can do it using if statements like the one I show on the code, but I would be repeating the code a LOT, so there has to be another way, could someone let me a hand please? The current if statement shows the profile page which is active <!-- This is saying: inherit everything from __base.html --> {% extends "storePage/partials/__base.html" %} <!-- Main base template which contains header and footer too --> {% load crispy_forms_tags %} <!-- To beautify the form at signup --> {% block body %} <div class="container bootstrap snippet"> <div class="row"> <div class="col-md-3"> <div class="list-group "> <label class="card-header">Personal Settings</label> {% if request.get_full_path == "/settings/profile/" %} <a href="{% url 'profile-settings' %}" class="list-group-item list-group-item-action active"><span class="fa fa-user"></span> Profile</a> {% endif %} <a href="{% url 'account-settings' %}" class="list-group-item list-group-item-action"><span class="fa fa-cog"></span> Account</a> <a href="{% url 'emails-settings' %}" class="list-group-item list-group-item-action"><i class="fas fa-envelope"></i> Emails</a> <a href="{% url 'billing-settings' %}" class="list-group-item list-group-item-action"><span class="fa fa-credit-card"></span> Billing</a> </div> </div> <!-- Center-right navBar--> <div class="col-md-9"> {% block settingsPageInfo %} {% endblock %} <!-- Here goes the user information on the profile page --> </div> </div> </div> {% endblock %} … -
Django refresh template with new values
I am trying to save checkbox inputs on a form, and when the user goes back to that page, they only view what checkboxes they viewed.

How to get the image id via a button to use it in views.py?
I'm pretty new to django and coding in generall, I'm trying to build an Instagram clone.. so my question is.. how can I comment on a post that is on the newsfeed(list of all uploaded images by every user), without leaving the newsfeed?

Bad gateway error when loading large sklearn model. Django/Ubuntu/Gunicorn/Nginx
I just developed a machine learning driven python 2.7 application which essentially loads a sklearn model with joblib and predicts a given dataset. On local host the application works perfectly, but when I deploy the django application on digital ocean (Ubuntu 18., gunicorn, nginx) I get a bad gateway error. I found out that the error is being raised when the model is being loaded with joblib. What I noticed as well is that the application works perfectly when a model that has the size of 8000 bites is being loaded but that but that the bad gateway error is being raised when I try to load a model of 60000 bites. What I have tried is to resize the droplet in order to avoid that the error is being caused by a lack of computing resources, but I still get the error! Unfortunately, I have no clue how to tackle the problem. So I hope that you guys can help me to find a way to resolve this issue. I appreciate any help. Thanks in advance. Kind regards Marcel -

How to embed images in blog post with React and Django
i'm developing a blog for a friend using React and Django, Now I have to develop the text editor that he's going to use to write the articles but I don't know what to do in case of he wanting to embed images(not uploading them to the backend but using a external source like imgur,etc) on the text field between paragraphs, I suppose that django is not going to accept an <img/> being posted to the database on a text field, so my question is: do i need to handle this on the frontend or in the backend? sorry if it is a dumb question but i've been thinking how to approach this and i can't find a way. models.py class Article(models.Model): title = models.CharField(max_length=150) text = models.TextField() created = models.DateTimeField(auto_now_add=True) -

Django Form submission leads to 404 Error
When an user submits a form, I am receiving the following error: Page not found (404) Request Method: csrfmiddlewaretoken=uaL0Ogej2bd0oSaNLXYwu1CxSPWz6mcs0PuXiwM2mpe01VecK5IVBK40xvqcFCJF&views=0&likes=0&slug=&name=do+do+ahadalfjkdas%3Bldfjksal%3B12321&submit=Create+CategoryPOST Request URL: http://127.0.0.1:8000/rango/add_category/rango/add_category/ Using the URLconf defined in tango_with_django_project.urls, Django tried these URL patterns, in this order: ^$ [name='index'] ^admin/ ^rango/ ^$ [name='index'] ^rango/ ^about/ [name='about'] ^rango/ ^category/(?P<category_name_slug>[\w\-]+)/$ [name='show_category'] ^rango/ ^page/(?P<page_name_slug>[\w\-]+)/$ [name='show_page'] ^rango/ ^add_category/$ [name='add_category'] The current path, rango/add_category/rango/add_category/, didn't match any of these.

how to get value of download button into my django view?
I have a download button in my HTML that has a href to a path on my system for the corresponding file. How can I load that path into my view when at user clicks download? Also this value is unique for each download button. Right now I have some HTML that looks like this. How do I grab the info from item.OutputPath into my view when clicked? <div class="dashboard-2"> <div class="tasks-finished"> <h1>Finished tasks</h1> </div> <div class="tasks-list"> <table> <tr> <th>Name</th> <th>Task ID</th> <th>Status</th> </tr> {% for item in query_finished %} <tr> <td>{{ item.TaskNavn }}</td> <td>{{ item.TaskID }}</td> <td><a href="{{ item.OutputPath }}">Download</a> </tr> {% endfor %} </table> </div> </div> If there's any other way that I can do this without exposing my system path in the href I would much prefer to know that. Thanks in advance. Additonal info: I need this value because i'm trying to save it as a variable to serve protected files using Nginx. -

Django - modal form and resubmission on page reload
I have got a modal contact form. The form works fine, but the page reload resubmits previously entered values. view.py ... if request.POST: form = ContactForm(request.POST) if form.is_valid(): entry = form.save() form = ContactForm() c.update(locals()) return render(request, 'template.html', c ) ... template.html <form action="." method="post" id="contact-form"> ... </form> I tried to clear the form in the GET request. Form fields are cleared, but this does not prevent submission on the page reload. else: #request.GET form = ContactForm() c.update(locals()) return render(request, 'template.html', c ) I have seen many examples suggesting a redirect. I do understand this approach, but in case of a modal form I would like to avoid the redirect. How to prevent modal form re-submissions? Is the redirect really the only way? -

Applying highlighting effect to text through replace() (Django 2.1)
I am writing a custom template filter that highlights the keyword put into the search engine in the search results page, just like in Google search results. Code for custom filter: register = template.Library() @register.filter @stringfilter def highlight(value, search_term): return value.replace(search_term, "<span class='highlight'>%s</span>" % search_term) The filter doesn't change the targeted word's CSS class into <span class='highlight'>. Instead, the output displayed text in the browser is literally <span class='highlight'>word</span>. E.g. "The most desired car brand right now is <span class='highlight'>Tesla</span>." How can I make it so that the replace() method actually changes the CSS class of the targeted word? -

How can I delete or download the needed document from folder by a clicking on webpage button?
Let's say the user cannot find the folder in the computer so it is easier to manage the folder files on webpage. I manage to show the folder file documents on webpage/Here is that webpage/, then I try to download or delete the needed document, but I get some errors.

Problems referencing model in function based view

Django Rest Framework ViewSets is returning selected records rather than all records in list view
I have a django application. I have one part of my app that is not working as I was expecting. As of now I am using the django rest framework view sets. What I want is two basically have 2 different list views in the same viewset. 1 that returns all of the accounts in the accountviewset and another list view that returns all of the accounts associated with a user based on the user foreignkey in the account model. The code below returns all the acccounts associated with a specific person, but I am not able to have a list view that returns all of the accounts in the database. class AccountViewSet(viewsets.ModelViewSet): serializer_class = AccountSerializer queryset = Account.objects.all() lookup_field = 'user__username' def list(self, request): queryset = Account.objects.all() serializer_class = AccountSerializer def get_object(self): return self.queryset.get(user__username=self.kwargs.get('username')) -
Django: Get queryset of nested objects in Retrieve API View
I'm creating a Django application with django-rest-framework and using djongo to connect to MongoDB. I have a nested model as such: class Group(models.Model): group_code = models.CharField( max_length=15, blank=False, unique=True ) users = models.ArrayModelField( model_container=User ) class User(models.Model): name = models.CharField( max_length=100 ) user_code = models.CharField( max_length=32, default=hex_uuid, editable=False ) class Meta: abstract = True I'm attempting to set up a view to retrieve a User at the following URL: urlpatterns = { url(r'^user/(?P<group_code>[\w]+)/(?P<user_code>[\w]+)/$', UserDetail.as_view(), name='user-detail') } Essentially, I want the view to display just the User's information instead of the Group's information. This didn't work, but is what I attempted: class UserDetail(generics.RetrieveUpdateDestroyAPIView): serializer_class = UserFullSerializer def get_queryset(self, *args, **kwargs): return Group.objects.get(team_code=self.kwargs['group_code']).users lookup_field = 'user_code' lookup_url_kwarg = 'user_code' However, users in this case is a normal list instead of a QuerySet. Therefore, the lookup_field attribute is not working correctly. Any thoughts on how to access the nested list users of type User as a QuerySet so that this view can work properly? -

How do I select information in other table based on the ID provided using a loop
Super new to django, working on my 1st test project. I have an app that's called customers. Inside of that, I have a few models. The 2 main, once I am trying to get to work right now, are Customer_Info, and Company_Info. On the template side I want to pull information in the for loop from both templates. Companies could have multiple customers (contacts). So inside of the customer info table, I am storing the company uuid they might belong to. Some customers would not have that ID as they are individuals and do not have a company association. Here are the 2 models. class Customer_Info(models.Model): #Name of the table id = models.AutoField(primary_key=True) cust_uuid = models.UUIDField(default=uuid.uuid4, editable=False, unique=True) first_name = models.CharField(max_length=32, blank=False) middle_name = models.CharField(max_length=32, blank=True) last_name = models.CharField(max_length=32, blank=False) phone = models.CharField(max_length=10, blank=False) email = models.CharField(max_length=64, blank=False) address_1 = models.CharField(max_length=64, blank=True, null=True) address_2 = models.CharField(max_length=64, blank=True, null=True) city = models.CharField(max_length=16, blank=True, null=True) state = models.CharField(max_length=2, blank=True, null=True) zipcode = models.IntegerField(blank=True, null=True) country = models.CharField(max_length=16, blank=True, null=True) company_uuid = models.ForeignKey('company_info', to_field='company_uuid', db_column='company_uuid', on_delete=models.PROTECT, blank=True, null=True) # miht need a nullable defaul https://docs.djangoproject.com/en/2.1/ref/models/fields/#foreignkey user_id = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.PROTECT, blank=False) # miht need a something else https://docs.djangoproject.com/en/2.1/ref/models/fields/#foreignkey date_added = models.DateTimeField(auto_now=True) def __str__(self): return … -
replace() method not working in custom template filter (Django 2.1)
