Django Status (Draft - Published) & Time (Published, Created, Updated) Issues
This is my model. Appears on admin side but not working. models.py class Post(models.Model): STATUS_CHOICES = ( ('draft', 'Draft'), ('published', 'Published'), ) published = models.DateTimeField(default=timezone.now) created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) status = models.CharField(max_length=9, choices=STATUS_CHOICES, default='draft') -
Set maximum value of integer field in template from context Django
I have a regular form with the basic template: <form method="post" action=""> {% csrf_token %} {{ form }} <input type="submit" value="submit"> </form> The form consists of three integer fields defined in forms.py class InitForm(forms.Form): row_1 = forms.IntegerField(initial=1, min_value=1) row_2 = forms.IntegerField(initial=1, min_value=1) row_3 = forms.IntegerField(initial=1, min_value=1) The maximum value is set at runtime using input from the user. I have added it to the context by using get_context_data()... in the form view class, but how do I set the maximum input value for the three integer fields in the template? I can already output the maximum value in the template by {{ maximum_value }} I am just having trouble adding it to the form fields. For reference I need the maximum value on all the fields -
Django Thinking User Is Logged In On One Page Only But on The Rest They Are Not
So I created a user profile by following this tutorial https://www.oodlestechnologies.com/blogs/How-to-Edit-User-Profile-Both-Django-User-and-Custom-User-Fields/ but every time I go the profile page when not logged in it shows that I am logged in I don't know if django thinks im the user that the profile im viewing. I tested it by adding this into the base.html <p>{% if user.is_authenticated %} You are logged in {% endif %}</p> It doesn't show it on any pages because im not logged in unless I go to view someones profile then it says im logged in which I am not models.py class UserProfileManager(models.Manager): pass class UserProfile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) avatar = models.ImageField(upload_to='avatars', blank=True) location = models.CharField(max_length=100, default='', blank=True) date_of_birth = models.DateField(default='00/00/0000', null=True, blank=True) website = models.URLField(default='', blank=True) bio = models.TextField(default='', blank=True) def __str__(self): return self.user.username def age(self): dob = self.date_of_birth tod = datetime.date.today() my_age = (tod.year - dob.year) - int((tod.month, tod.day) < (dob.month, dob.day)) return my_age def createProfile(sender, **kwargs): if kwargs['created']: user_profile = UserProfile.objects.created(user=kwargs['instance']) post_save.connect(createProfile, sender=User) views.py def public_profile_view(request, username): user = User.objects.get(username=username) userprofile = UserProfile.objects.all() # date_joined = request.user.date_joined # last_login = request.user.last_login context = { 'user': user, 'userprofile': userprofile, # 'date_joined': date_joined, # 'last_login': last_login, } return render(request, "/account/profile/public_profile.html", context) def profile_edit_view(request): userprofile = … -
How do I fetch all the items in a list from an external API in Django?
So this is my api - https://api.myjson.com/bins/vvjiu Here is a portion of my view.py def postsign(request): product_list = Product.objects.all() product_data = [] for product in product_list: r = requests.get('https://api.myjson.com/bins/vvjiu').json() products = { 'name': r['products'][0]['name'], 'image': r['products'][0]['image'], 'price': r['products'][0]['price'], 'description': r['products'][0]['description'] } product_data.append(products) print(product_data) context = {'products':products} return render(request,"Welcome.html",context) And here's my product view in Welcome.html div class="container carousel-inner no-padding"> <div class="col-xs-3 col-sm-3 col-md-3"> {% for products in product_data %} <div class="card" style="width: 18rem;"> <img class="card-img-top" src="{{ products.image }}" alt="Card image cap"> <div class="card-body"> <h5 class="card-title">{{ products.name }}</h5> <p class="price">{{ products.price }}</p> <p class="card-text">{{ products.description }}</p> <a href="#" class="btn btn-primary">Add to cart</a> </div> </div> {% endfor %} </div> </div> This returns just the first item from the API, that is, the Acoustic Guitar.

Django set user's language based on IP then remember it in session with custom middleware
I want to play a little bit with language settings and have some problems through [TODO] set users location based on theirs IP - DONE (code below) some customers may want to change language.

Querying datetime object in django doesn't work
I'm facing the issue of wrong query result due to timezone issue. I've read several answers, but most of suggest USE_TZ = False.

Django_tables2 How to identify each table when using MultiTableMixin in Django Template
I am trying to render two seperate tables on a different location in a Django template. However, the official documentation only shows how to render the tables in a loop: {% for table in tables %} {% render_table table %} {% endfor %} This works, however, I want to render a table based on a identifier(such as name). The following code does this, but it doesn't make it clear what table is being rendered: {% render_table tables.0%} Something among the lines of: {% render_table tables.newstable %} would be ideal. I've had slight succes by removing the MultiTableMixin class, then rendering the tables using get_context_data(), however, this breaks pagination. def get_context_data(self, **kwargs): context = super(TeamHomeTest, self).get_context_data(**kwargs) team_id = self.kwargs['teamid'] team = Tmteams.objects.get(teamid=team_id) q1 = Tmteamsusers.objects.all().filter(teamid=team_id) category_ids = [] categories = nwscategory.objects.all().filter(teamId=team_id) for cat in categories: category_ids.append(cat.categoryid) q2 = nwseditor.objects.filter(categorie_id__in=category_ids) team_member_list_table = TeamMemberListTable(q1) team_news_list_table = TeamNewsTable(q2) context['table1'] = team_member_list_table context['table2'] = team_news_list_table context['team'] = team self.tables=[context['table1'], context['table2']] return context My current get_tables() method looks like this: def get_tables(self): team_id = self.kwargs['teamid'] q1 = Tmteamsusers.objects.all().filter(teamid=team_id) category_ids = [] categories = nwscategory.objects.all().filter(teamId=team_id) for cat in categories: category_ids.append(cat.categoryid) q2 = nwseditor.objects.filter(categorie_id__in=category_ids) table1 = TeamMemberListTable(q1) table1.name = "test" tables = [ table1, TeamNewsTable(q2) ] return tables -

Django sending context to multiple views
I'm trying to achieve following tasks in Django: First page: User fills a large Job application form and that data is sent to Second page Second page: User reviews his previously filled data and proceeds to third page Third page: User pays the amount(came from Second page) and once paid, then only all this data is saved to DB. I've done First page work of filling form and then sending that data to Second page. Here's my views.py def applyJob(request,id=None): job = get_object_or_404(AddJob, id=id) if request.method == 'POST': context = { 'jobName': job.jobName, 'jobID' : job.pk, 'cfName' : request.POST.get('candidateFirstName'), 'cmName' : request.POST.get('candidateMiddleName'), 'clName' : request.POST.get('candidateLastName'), ...... return render(request,'reviewAppliedJob.html',context) else: context ={ "jobName": job.jobName, "id": id, } return render(request,'applyJob.html',context) Since I'm sending the context data using return render(request,'reviewAppliedJob.html',context), URL is not changing and so it's not going to my reviewAppliedJob views and so I cannot write code to go to Third page. def reviewAppliedJob(request): return HttpResponse('done....') For that, I can use HttpResponseRedirect('/reviewAppliedJob') instead of render in applyJob() but it will not send my context data. Django allows sending context either using render(), messages framework, url params or session. But since I have large amount of data, I don't know which one … -

Django Channels: issue using sessionStorage to store username with JavaScript, better way to store variable?
I am using Django Channels to build a chat app. It is not backed by a database and I am trying to handle everything via JavaScript. The program works except for a problem with sessionStorage. The error I am getting is that the username always displays as the username in the active browser. For example, if there are two users in a room, User1 and User2, all messages on User1's screen will display as from User1, even those sent from User2. On User2's screen all message show as from User2. Here is the code handling the chat window: // Declare variables var userName; document.getElementById("chatname").innerHTML = roomName; // Set User window.onload = function(){ userName = sessionStorage.getItem("user"); if (userName==null || userName===false) { userName = prompt("Please enter a username:"); }; return userName; } // Create Websocket var chatSocket = new ReconnectingWebSocket( 'ws://' + window.location.host + '/ws/chat/' + roomName + '/'); // Send message chatSocket.onmessage = function(e) { var data = JSON.parse(e.data); var message = data['message']; var currentDate = new Date(); var currentTime = currentDate.toLocaleTimeString(); document.querySelector('#chat-log').value += (userName + " " + currentTime + ': ' + message + '\n'); document.getElementById("chat-log").scrollTop = document.getElementById("chat-log").scrollHeight; }; chatSocket.onclose = function(e) { console.error('Chat socket closed unexpectedly'); }; document.querySelector('#chat-message-input').focus(); … -

Can i use a picklist to display attending users and absent users in the admin environment of django?
Right now I have 2 lists displayed with the exact same content. One is used for selecting attending users and the other one is used for the users that are absent during the meeting. This doesn't look nice. I would like to have 2 list views next to each other. The first one is the attending list view which has all the users shown. The absent list is empty but i can drag or use a cursor button to swap users from the Attend list to the Absent list. To give you an example of what i mean: Heres an example component in angular primefaces. https://www.primefaces.org/primeng/#/picklist If you select a car brand in the left list and press the upper button then the car brand will be removed from the left list and displayed in the right list. Does django support such a display feature? Thank you -
Reason to use Postman for Django Rest Framework
I'm used to test Django Rest Framework apps with the test tools available directly in Django and DRF. It's possible to setup a dummy client and expose all the REST methods. At the same time, I see many posts talking about Postman for API testing. I fail to see where the advantage would be. Is there any reason for me, a single developer, to use Postman? Or perhaps there is only an advantage for shared projects? -

Even if this group has all the perms, I am getting You don't have permission to view or edit anything. message once on the admin screen. According to django: A user will get all permissions granted to each of their groups. Am I missing something crucial ? Do I need to write some code to get the groups perms in my user perms ? I am using the base: django admin django users django perms In a second time, I would like this group to have access to add, edit, delete my models but not be able to see users, groups and permissions
