Python Django How to Create Hash Fields inside django models.py
I'm working on a Python(3.6) & Django(1.10) project in which I need to save some user credentials of the third party services like username, password, and email, I'm implementing only rest API, so there's no form.py at all. So, How can I make hash fields inside models.py file? Here's my current models.py: class DeploymentOnUserModel(models.Model): deployment_name = models.CharField(max_length=256, ) credentials = models.TextField(blank=False) project_name = models.CharField(max_length=150, blank=False) project_id = models.CharField(max_length=150, blank=True) cluster_name = models.CharField(max_length=256, blank=False) zone_region = models.CharField(max_length=150, blank=False) services = models.CharField(max_length=150, choices=services) configuration = models.TextField(blank=False) routing = models.TextField(blank=True) def save(self, **kwargs): if not self.id and self.services == 'Multiple' and not self.routing: raise ValidationError("You must have to provide routing for multiple services deployment.") super().save(**kwargs) I want to add three new hash fields like username, password & email.

Can I use custom django tags to pass a value to another view?
I am currently using modelformset_factory to display several forms in an update class-based view.

Is there a way to restrict apps based on IP?
I'd like to be able to only allow certain apps to be used from the corporate office which has a static IP. Is there a django package that I can use to do this? If so do you know if it can be used as an additional security measure? Certain apps and the data in those apps I wouldnt want to be accessible by anyone outside the office. I already have pretty good app security but as an additional security measure is this a good option? Thanks -

Why do I have to state 'atomic=False' when I change model name in Django?
Okay so I was following Django 2.0 tutorial on the official documentation when I realized I named a model 'Questions' instead of 'Question'.

CSRF Token Name on Django Documentation is not Matching the Actual Name of the Variable in AJAX Header
I was struggling to send and recieve CSRF token, and I found, in the end, that Django was not able to get the token value because its name was different from the recommended one in its documentation. Why? (I am doing AJAX on a HTTPS address and requests are cross-site.) function csrfSafeMethod(method) { // these HTTP methods do not require CSRF protection return (/^(GET|HEAD|OPTIONS|TRACE)$/.test(method)); } $.ajaxSetup({ beforeSend: function(xhr, settings) { if (!csrfSafeMethod(settings.type) && !this.crossDomain) { xhr.setRequestHeader("X-CSRFToken", csrftoken); } } }); Here, the name is X-CSRFToken, which somehow becomes HTTP_X_CSRFTOKEN. On the other hand, Django is looking up the cookie under CSRF_COOKIE. Line 278 in csrf.py of CsrfViewMiddleware: csrf_token = request.META.get('CSRF_COOKIE') if csrf_token is None: # No CSRF cookie. For POST requests, we insist on a CSRF cookie, # and in this way we can avoid all CSRF attacks, including login # CSRF. return self._reject(request, REASON_NO_CSRF_COOKIE) I cannot change the variable name because I get this error: Request header field CSRF_COOKIE is not allowed by Access-Control-Allow-Headers in preflight response. So, I ended up changing the variable name in the source code from CSRF_COOKIE to HTTP_X_CSRFTOKEN. Are there any way to make this work? (I do not do @csrf_exempt, so please do … -

Can I Destructively Alter My Database in a Django View?
So I'm loading up my queryset to send to my template. One of the objects is incident. Now, each incident has a bunch of attributes like "status" and "employee", so in my template I can just do // incident.html // {% for incident in incidents %} <h1> {{ incident.employee }} - {{ incident.status }} </h1> {% endfor %} Now, for convenience I want to add new properties that didn't exist before to incident, like "mood" or whatever, I can add // views.py // def get_context_data(self, **kwargs): ... for incident in incidents: incident.mood = "scary" And then in my template I can just access incident.mood along with incident.status and incident.employee. // incident.html // {% for incident in incidents %} <h1> {{ incident.employee }} - {{ incident.status }} </h1> <h3> It was very {{ incident.mood }} </h3> {% endfor %} So, what I want to know is, is it possible to mess up and destructively alter the database if I'm not careful here?

display rawqueryset value in a model using django @property field
I am trying to insert a @property field into a django model. However this field gets its value from a RawQuerySet like so; class Medication_List(models.Model): id = models.AutoField(primary_key=True) medication_name = models.CharField(max_length=250, blank=True, editable=True) ... def stock_level(self): # "Returns the totalstock remaining" current_stock = Medications_Bridge.objects.raw("SELECT T3.total_quantity_sold AS total_quantity_sold FROM (SELECT * FROM ... return({'current_stock' : current_stock}) stock = property(stock_level) def __str__(self): return "%s %s %s" % (self.medication_name, self.supplier,self.stock) This works fine with no errors, but django is not showing value for the queryset in the str function, rather it just shows the whole query just as it was written above. i.e. "SELECT T3.total_quantity....." I want to know if it is even possible to use @property field to show a value from another unrelated database table. I have seen some examples on StackOverflow where calculated values are shown using values from the same model with help of self.field_name but i cant find any example where the values for the calculations are derived from another model or from a raw SQL query. Kindly help. Any hint will be very much appreciated. Thanks -
Django/Python/xhtml2pdf - Help getting xhtml2pdf to render a DetailView
I'm trying to get xhtml2pdf to render a DetailView to pdf, but I'm running into some issues. To be more specific, I have an app that's similar to a blog. User logs in, creates a new "post", and then can view it. I want to be able to allow the user to save that post to pdf. I've gone to my extent of knowledge (admittedly limited still) with Django and cannot figure it out. I've followed multiple tutorials and have xhtml2pdf working for static pages, but not for ones that require a pk or pulling data from the database. The view I'm trying to save looks like this: class SingleCharacter(LoginRequiredMixin,generic.DetailView): model = models.Character def get_context_data(self, **kwargs): context = super(SingleCharacter, self).get_context_data(**kwargs) return context Alternatively, if anyone knows of another way to save html to pdf that works with django, I'd take advice on that, as well! Any help would be greatly appreciated! Thank you! -

Django redirect cannot resolve URL
I have a pretty simple Django app with a form. After the form has been validated, it's supposed to redirect to the start page of the app. I get the following error: django.urls.exceptions.NoReverseMatch: Reverse for 'overview' not found. 'overview' is not a valid view function or pattern name. The relevant path in urls.py is: urlpatterns = [ path('overview', views.overview, name='overview'), ...] The view is in the same views.py as the redirecting view: def overview(request): ... return render(request, 'feedback/overview.html', context) The view with the redirect call looks like this: def make_submission(request): if request.method == 'POST': form = FeedbackForm(request.POST) if form.is_valid(): post = form.save(commit=False) post.approved = False post.save() return redirect('overview') else: form = FeedbackForm() return render(request, 'feedback/make_submission.html', {'form': form}) The form data are saved in the db, but the redirect fails.

Django getting the incorrect form name, value, or ID from an unchecked form (that was previously checked)
I have a view which displays many forms (which are individual checkboxes per form). I would like to get the value of the checkbox that was previously checked, but then unchecked. I have tried a number of things, including getting the form id/label name, but for some reason when I uncheck 1 box (1 form), it is returning the wrong box/form as the one that was unchecked. In fact, it is simply just returning the first form in my list of forms, and not the one that was unchecked.
