I'm having trouble with my Jquery-Ajax upvoting code
In my project, it is possible to upvote posts. This works fine, when I'm not using Jquery-Ajax. It reloads the page, though, and I don't want that. I implemented some Jquery-Ajax to do a POST request, and update the button to say upvoted. Unfortunately, this causes all posts in the list to be upvoted, instead of just the one that I clicked. Let me show you the HTML (inside the post list for loop): {% with user=request.user %} <a class="upvote" href='#' > <span class="btn btn-primary" aria-hidden="true"> Upvote | {{ post.followers }} </span> </a> <span style="display: none; class="upvoted btn btn-primary" aria-hidden="true"> Upvoted | {{ post.followers }} </span> {% endwith %} That was the HTML for the upvote and upvoted buttons. Here is my Jquery script: <script src="{% static 'posts/jquery-3.1.1.js' %}"></script> <script type="text/javascript"> $(".upvote").click(function(event) { $.ajax({ url: "{% follow_url post %}?next={{ request.path }}", success: function(data) { event.preventDefault(); $(".upvoted", this.parentElement).fadeIn(); } }); }); </script> To sum it up, how do I cause this function to only vote on the post that I click, instead of upvoting every one in the list? Thanks! -
Django Heroku CreateView Post Bad Request 500 in Production only
I'm deploying a Django App live for the first time, and everything has gone relatively smoothly so far. My site works fine, except for one CreateView (EstRequestCreateView) that works locally, but when I try to create new Estimate Request in Production I receive a Bad Request (500) response. I've added some print statements to the code just to identify where it's failing, but it appears to be behind the scenes somewhere as it makes it all the way through both of my functions no problem. Here is my View: class EstRequestCreateView(CreateView): model = EstRequest # fields = ['market', 'builder', 'plan', 'due_date', 'notes'] form_class = EstRequestModelForm template_name = 'requests/request_form.html' success_url = '/requests/' def post(self, request, *args, **kwargs): if request.user.is_authenticated(): print(request.POST) form = self.get_form() print('form') if form.is_valid(): print('is_valid') return self.form_valid(form) else: print('not valid') return self.form_invalid(form) def form_valid(self, form): print('form_valid func') form.instance.added_by = self.request.user print('user') market = self.request.POST['market'] print('market') note = self.request.POST['notes'] print('notes') due_date = self.request.POST['due_date'] print('duedate') form.instance.trello_id = create_card(market, note, due_date) print('trello created') return super(EstRequestCreateView, self).form_valid(form) And here is my log in Heroku: Dec 21 15:40:51 ao-prime app/web.1: <QueryDict: {'csrfmiddlewaretoken': ['ympCUozBK7qYEoMHgAffBWCoQce7nrqC'], 'plan': [''], 'due_date': ['2016-12-26 18:40:39'], 'market': ['1'], 'builder': ['1'], 'notes': ['Test 1 with Logging']}> Dec 21 15:40:51 ao-prime app/web.1: form Dec … -

Django Create Multiple Objects (Same Model) From One Form
I have been researching this issue for a couple days now with no luck. Hoping someone out there can help. Let's say we have the following models: User model (django.contrib.auth.models) class Children(models.Model): name = models.CharField(max_length=200, blank=False) user = models.ForeignKey(User, on_delete=models.CASCADE) The goal: When a new user wants to create an account, they will fill out the User form and be able to add x amount of children to their account. Essentially, the template will have a user form, and x amount of children forms (depending on how many children the user has) all bundled under the same < form > tag. I used this reference when creating the view: https://collingrady.wordpress.com/2008/02/18/editing-multiple-objects-in-django-with-newforms/ The view looks like it should work. My problem is with the template. The trick is that I am not sure how many children each new user will have so I can't hardcode the children form. Does anyone know what a template would like look for this issue or how I can accomplish my goal? -
Django view not rendering after Ajax redirect
The main page of my website has multiple buttons at the top. Whenever one of these buttons is pushed, a get request is sent to a django view, which is redirected and a queryset of django models is filtered and eventually displayed on the web page. I know that my ajax works because the terminal says the request is redirected properly. The function it redirects to also seems to be working, as it is quite simple and has not thrown any errors. However, my view remains the same and I'm not sure why. urls.py url(r'ajax_filter/', views.ajax_filter, name='ajax_filter'), url(r'filter=(\w+)/$', views.filtered_index, name='filtered_index'), views.py def filtered_index(request, filter): clothes = Clothes_Item.objects.filter(gender=filter) if request.user.is_authenticated(): favorite_clothes_ids = get_favorite_clothes_ids(request) return render(request, 'test.html', {'clothes': clothes, 'favorite_clothes_ids': favorite_clothes_ids}) else: return render(request, 'test.html', {'clothes': clothes, }) def ajax_filter(request): if request.is_ajax(): gender_filter = request.GET.get('gender_filter') #filter type if gender_filter is not None: return HttpResponseRedirect(reverse('filtered_index', args=[gender_filter])) return HttpResponse('') -

Learning Django - models.py ForeignKey or ManyToManyField or else?
Trying to get some Django skills. I would like to have a class with one field being multiplied. So I can have more then one connected to my main class with an option of being active or not (for future needs). So my subclass would look something like this: class Subclass(models.Model) STATUS=( ('A', Active), ('U', Unactive) status = modelsCharField(max_lenght=1, choices=STATUS) name = models.CharField(some options) On main class I would like to call it as a reference but if I go for : field=models.ManyToManyField(Subclass) It is represented as a second table and for each entity I have to chose from all the entities of it. So if I have 2k entities in subclass I have to scroll true all of them to find my connection (in default admin page for instance) I do not want that. All I need is 2 out of 2k entities that are connected and displayed in admin. And later on anly those with status Active would be displayed on the page itself. So I figured I shall try a ForeinKey relation: field=models.ForeignKey(Subclass, on_deleate=models.CASCADE) This gives me errors about missing default values during migration though. Any help would be welcome, since I am a bit stuck right … -
Django - Retrieve Values of Checkboxes
How do I retrieve the values of multiple html checkboxes and send it back to my view? The checkboxes have the same name: <input type="checkbox" value="document_1" name="checkbox_1"> <input type="checkbox" value="document_2" name="checkbox_1"> <input type="checkbox" value="document_3" name="checkbox_1"> I'm trying to give the user the option the select multiple checkboxes and then send that data back to a Django view. My hope is to send the data back to a Django view as a list of all the selected values with Ajax, although I'm just working out a regular form right now. So If I selected the first and last checkbox, I would send this back to the view: data = ["document_1", "document_3] I have tried setting a variable like this: var data = $('.checkbox_1:checked').val() and I'm still working on the Ajax but haven't been able to make much progress. -
Django: Change url based on result of user authentication
I'm new to django and getting stuck on what I think is a simple issue. I've set up user authentication in my app which is working fine, the problem I'm having is with the url address that appears when my form is submitted. Here is the problem: The action on my form that takes in a user's login credentials is set to "{% url 'home' %}" which is a reference to /dashboard/home. This is exactly what I want the url to be in the event of a successful login. However, when the login is unsuccessful, I want to stay on the login url, which is /dashboard/login. As you can imagine, what's happening instead is that in the event of an unsuccessful login, the url is still changing to /dashboard/home. I think this is misleading for the user and generally just bad practice, but I don't know how to dynamically change the url depending on the result of the login attempt. How can I change the url to /dashboard/login when the attempt is unsuccessful but keep it as /dashboard/home when it is successful? -

Nginx 502 Bad Gateway - Django - Gunicorn - When running MySQL reports (Stored Procedures) that take longer than 30 seconds
I have a Django, Nginx, Gunicorn, and MySQL on AWS. Running a postback from django which calls a stored procedure that takes longer than 30 seconds to complete causes a return of "502 Bad Gateway" nginx/1.4.6 (Ubuntu).

Suggested architecture for rewrite a client desktop app written in python (pyqt) as a web app
I have a desktop client application written in python. I used pyqt to develop the gui. This application mainly works exploiting a bunch of very specific python libraries. In order to have data some services provided by a web server are used. Now I need to rewrite this client app as a web app, because my real need is to allow users to use this application without downloading any software on their laptops. My question is, in order not to waste all the work and all the code already written in python with pyqt and all this other libraries, in your opinion what's the best solution to adopt? Keep in mind also that I spendt few days tring to figure out if rewriting the application with javascript and angularjs could be possibile, but I realized that its a lot of work to do and a lot of already written code to waste. In addition could be django or flask a good idea also? thanks in advance -
Is there a converter between django.forms.Form and rest_framework.serializers?
I already have plenty of forms defined in my django 1.9 project. Now I need to export them as REST (DRF 3.5.3) as well. With just a bit of hacking, I was able to provide GET and PUT methods. But I also need to provide the OPTIONS method and I can't seem to find anything that would help me do that. So, is there something that would convert an instanced form to DRF Serializer / ViewSet? -

Django-debug-toolbar extremely slowing down loading page
I want to profile my project to figure out what indices to create in db. I've installed django-debug-toolbar. The problem is that it is extremely slowing down page loading.

Creating a 21 character unique field for a model in Django
I know the id is unique by itself, I want to create a unique field thats longer and less easy to guess. In short, this field will be a unique, 21 character alphanumeric string. I am doing this using this code below: class Organization(models.Model): name = models.CharField(max_length=255) key = models.CharField(max_length=21, unique=True, blank=True, null=True) def save(self, *args, **kwargs): if self.key == '' or self.key == None: key = '' for i in range(21): key += random.choice(string.lowercase + string.uppercase + string.digits) if Organization.objects.filter(key=key).exists(): self.save() # Try again else: self.key = key super(Organization, self).save(*args, **kwargs) In the save method, I do the following things: See if the object's key exists or not. If not, I generate a 21 character key. Then I check if an Organization with the key I generated exists or not. If not, then the object's key is set to the generated one and saved. Is this the right way to do this? Is there a better way with less code perhaps? Also, notice how my key field is unique, but also can be blank. Can that be an issue? So far, this has worked pretty well. Any help is appreciated.
