Minimal max_length of a Django CharField to store the output of the sign method of a Signer object (django.core.signing)
I have to sign a value, in my case emails, and I have to store the signed value in a Django CharField. I am using the Signer.sign method of the django.core.signing module. Since I would like to insert also the max_length parameter for the db field, my question is, what would be the minimal value I can put in the max_length in order to always successfully store it in the db. -
Update view not working? Django
The users are able to create an aircraft post at this url: url(r'^upload/aircraft/$', aircraft_create, name="aircraft_create"), I've created a summary page where all of the users posts are displayed. They're able to edit and delete their posts here. The url: url(r'^account/uploads/$', upload_overview, name="account_uploads"), However, I want the user to be able to edit their posts on their summary page. The way I got it set it now, is that they can edit at upload/aircraft/edit, but I want to to be account/uploads/edit. I've set it up like that but it's not doing anything? Any clues as to what it might be? Aircraft/views.py def aircraft_create(request): form = aircraft_form(request.POST or None) if form.is_valid(): instance = form.save(commit=False) instance.user = request.user instance.save() messages.success(request, "Your upload has been successfully added!") return HttpResponseRedirect(instance.get_absolute_url()) else: messages.error(request, "There seems to be something wrong.

Modifying django form field choices with few hundred items causes freeze / not responsive
I want to dynamically modify a field choices in django form. Because item's list is pretty long (more then 650 items), I store them in django cache. However, when I want to inject them as field choices, application become unresponsive (sometime returns ERR_EMPTYRESPONSE). My view: class HomeView(TemplateView): template_name = 'web/pages/homepage.html' def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs) categories = cache.get_or_set('categories_list', Category.objects.values('uuid', 'code', 'name'), 3600) categories_choices = [(o['uuid'], '{} ({})'.format(o['name'], o['code'])) for o in categories] print(categories_choices) #its printing proper choices here context['form'] = SearchForm() context['form'].fields['category'].choices = categories_choices #this line causes freeze/timeout return context Any idea what is happening there? Maybe 600+ items as dropdown choices is too many? -
Django check if authenticated user is same as the author of the post?
I want to display edit button only if the user is authenticated as the author of the post. example: 1.example.com/username1 2.example.com/username2 i want to take to user to the edit profile page, i got all the permission working correctly and set the views accordingly. My Problem: i loggedin as username1 so i should not be able to access example.com/username2/edit/. i got this to work in the views by adding some permissions, but i dont want to display the edit button when the loggedin username1 views the page of username2. Now i use {% if user.is_authenticated %} and this results in display the edit button on page of username2 even though the loggedin user is username1. Any simple solutions that can be used in the templates directly? -

Django pagination with bootstrap

Reload the table without refreshing the page in Django
Have small table that needs to be updated every 10 seconds with new data. Entire website is working in Django. JSON is parsing data into 1 table and rewriting the data every 10 seconds in database. The website is showing the data from the database. The procedure I need is to refresh the front-end table with new data every 10 seconds - it would be the AJAX I assume, can you help me write the code for it? It would not append data to the table, just keep refreshing it. Example - The table in the database has fixed 10 rows of data and it is being refreshed by JSON. The front-end would always show 10 rows, so every 10 seconds, the table (front-end) would always show 10 rows with the new data. Here are the python files views.py def prices(request): prices = Price.objects.all().order_by('id') return render(request, 'prices.html', {'prices':prices}) prices.html <div class="col-md-8"> <table class="table table-striped"> <thead> <tr> <th>TYPE</th> <th>NAME</th> <th>PRODUCT</th> <th>VALUE</th> </tr> </thead> <tbody> {% for price in prices %} <tr> <td>{{ price.type }}</td> <td>{{ price.name }}</td> <td>{{ price.product }}</td> <td>{{ price.value }}</td> </tr> {% endfor %} </tbody> </table> </div> urls.py urlpatterns = [ url(r'^prices/', product_views.prices, name='prices'), url(r'^admin/', admin.site.urls), ] -

Django - Authentication credentials were not provided
I'm working with an endpoint that seems to be built on Django. Attempting to setup basic aJax communication to it via POST I wrote: jQuery.ajax({ type: "POST", url: "http://API-ENDPOINT-URL", data: "", dataType: "json", crossDomain: false, beforeSend: function(xhr){ xhr.setRequestHeader('Authorization', 'Token <TOKEN THAT I WAS PROVIDED>' ) }, success: function(results) { reqListener(results) } }); With those code a few things happened: I first got a CORS error since I'm trying to build on my local server. I installed this chrome extension to bypass it. (I have no access to the server to enable CORS) 2.I get this error in the console: XMLHttpRequest cannot load http://API-ENDPOINT-URL. Response for preflight has invalid HTTP status code 401 looking at the Chrome console for the network request I see this comes back: {"detail":"Authentication credentials were not provided."} What am I missing? Am I incorrectly sending the authentication token? -
