Making script content 'safe' for HTTPS display (Bokeh)
I was searching for a solution and came across a removed question from maria saz. Fortunately, I was able to see it cached by google. Since I have the exact same question, I borrowed the original text: """ I'm building a website with Bokeh plots, using inline embedding. However, using an https connection to the site blocks the plots from being rendered, as the source is deemed 'unauthenticated'. Is there a way to solve this? In the 'Security Overview', it says: Blocked mixed content Your page requested insecure resources that were blocked. Where the two blocked requests were: bokeh-0.12.1.min.css bokeh-0.12.1.min.js ... """ In my case, I can add a bit of further information. The site is being built using django and google app engine, and if I allow the unsafe content, the bokeh plots work as expected. How can I serve my content so the scripts will load without the warning? -
Django, eclipse, localhost: How to allow caching of static files
I am using Django's static_serve to serve static files in our development environment (localhost, Windows). How do I add a response header such that the files will be cached on my browser? I am using Eclipse debug mode. This is not an issue in production where I'm using a CDN to serve static files. The browser used to cache these files, but at some point stopped. I don't know if it's an Eclipse thing or...? urlpatterns = [ url(r'^static/(?P<path>.*)$', 'django.views.static.serve', {'document_root': settings.STATIC_ROOT}), ... From this post Turn off caching of static files in Django development server it seems that the default is to allow caching, but that's not what I'm seeing. -
Using save method to extend M2M relationship
I have a model like this class Authority(models.Model): name=models.CharField(max_length=100) country=models.ForeignKey(Country) category=models.ForeignKey(Category) competitors=models.ManyToManyField("self",related_name="competitors") I want authorities having the same country and category and itself to be automatically give an M2M relationship,so i did this def save(self,*args,**kwargs): z=Authority.objects.filter(country=self.country).filter(category=self.category) this_authority=Authority.objects.get(id=self.id) for a in z: this_authority.competitors.add(a) super(Authority,self).save(*args,**kwargs) It wasn't working and not bringing any error,I also tries this below def save(self,*args,**kwargs): z=Authority.objects.filter(country=self.country).filter(category=self.category) this_authority=Authority.objects.get(id=self.id) self.competitors=z super(Authority,self).save(*args,**kwargs) What might be wrong with my code?Thanks in advance. -

How to set equal fields in formset?
I have a formset with maximum number of forms 2. It's a reservation form. When user choose "round trip", the second form is shown and activated to choose date and time of the second ride. The problem is that both forms contain fields like first_name, last_name which is required. In fact, user have to fill first_name, last_name once - in the first form and after submit, two Reservation objects would be created - with the same first_name, last_name... . In the template, I render only date,time,last_name,first_name for first form and if round trip is checked, date and time for the second form. Problem is that when I click to submit, it returns error - is_valid() is False because first_name,last_name and telephone are required for second form too. My idea was simple: def view(request): if request.method == 'POST': if formset.is_valid(): first_name = formset[0].cleaned_data['first_name'] last_name = formset[0].cleaned_data['last_name'] telephone = formset[0].cleaned_data['telephone'] date_1 = formset[0].cleaned_data['date'] time_1 = formset[0].cleaned_data['time'] date_2 = formset[1].cleaned_data['date'] time_2 = formset[1].cleaned_data['time'] Reservation.objects.create(first_name=first_name, last_name=last_name, date=date_1, time=time_1...) Reservation.objects.create(first_name=first_name, last_name=last_name, date=date_2, time=time_2...) What would you do? -
Django - How to restrict foreign key choices in dropdown menu depending on datatime field
I have form for adding data in database and I want to restrict foreign key choices in my dropdown menu. It have to be restricted on my finishDate field. If finishDate is date before today (eg. today is 21-08-2016 and finishDate is 30-06-2013), then I don't want to show foreign key value of that finishDate. What is the easiest way to do this? I am relative new at this, so I need help. models.py class Account(models.Model): startDate = models.DateField(verbose_name="Start") finishDate = models.DateField(verbose_name="Finish") def __str__(self): return 'A{}'.format(self.id) class Net(models.Model): date = models.DateTimeField(default=datetime.now()) MB = models.IntegerField(validators=[MinValueValidator(1)],default=randint(100,2000)) idAccount = models.ForeignKey(Account, on_delete=models.CASCADE, verbose_name="Account") def __str__(self): return 'Record {}'.format(self.datum) forms.py class NetForm(ModelForm): class Meta: model = Net fields = ['idAccount'] views.py @login_required(login_url="/accounts/login/") def net(request): if request.method == 'POST': form = NetForm(request.POST) if form.is_valid(): internet = form.save() return HttpResponseRedirect('/') else: form = NetForm() return render(request, 'project/Net.html', {'form': form}) Thanks a lot! -
Saving django model with DateTime fields
Model: class Meal(models.Model): created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) collection_from = models.DateTimeField(blank=False, null=False) discount_price = models.DecimalField(blank=False, null=False, decimal_places=2, max_digits=4) normal_price = models.DecimalField(blank=True, null=True, decimal_places=2, max_digits=4) available_count = models.IntegerField(blank=False, null=False) name = models.CharField(blank=False, null=False, max_length=255) active = models.BooleanField(blank=False, null=False, default=True) Now, when I'm saving it's instances the created_at and updated_at values are set properly, eg: 2016-08-21 13:13:57.585472+02. collection_from value should be nearly the same as those two previous ones, but it's getting set to point to the next day, eg: 2016-08-22 01:00:00+02 which I don't get at all :). The collection_from value looks like that when sent by the browser: 2016-08-21 23:00. I believe I have proper settings set up int the settings.py file: TIME_ZONE = 'UTC' USE_TZ = True So what's the problem here? How do I make django save collection_from value the same way as created_at or updated_at? -

django custom property to return filtered field
In a django app, with an existing databse, I've used inspectdb to build a model: class Sensorparser(models.Model): """ a read-only implemenation to access the MeshliumDB """ id_wasp = models.TextField(blank=True, null=True) id_secret = models.TextField(blank=True, null=True) frame_type = models.IntegerField(blank=True, null=True) frame_number = models.IntegerField(blank=True, null=True) sensor = models.TextField(blank=True, null=True) value = models.TextField(blank=True, null=True) timestamp = models.DateTimeField() raw = models.TextField(blank=True, null=True) parser_type = models.IntegerField() def save(self, *args, **kwargs): return def delete(self, *args, **kwargs): return class Meta: managed = False db_table = 'sensorParser' I added the save and delete methods, because this should be a read-only model. One of the fields is sensor, which defines strings for different, well, "sensors" (e.g. BAT, ANE, etc.). I would like to have a property: @property def battery() return self.sensor.objects.filter(sensor='BAT') How should I accomplish this? -
Filtering Paginated Results Django
I extended ListView in Django to paginatedListView as following class paginatedListView(ListView): per_page = 20 def get_queryset(self): qs = super(paginatedListView,self).get_queryset().order_by('-creation_datetime') paginator = Paginator(qs,self.per_page) try: page_num = int(self.request.GET.get('p', '0')) except ValueError: page_num = 0 try: page = paginator.page(page_num + 1) except (EmptyPage, InvalidPage): page = paginator.page(paginator.num_pages) self.cl = InlineChangeList(self.request, page_num, paginator) self.paginator = paginator if self.cl.show_all: return qs else: return page.object_list def get_context_data(self,**kwargs): context = super(paginatedListView,self).get_context_data(**kwargs) context['cl'] = self.cl return context Now I have another view which extends paginatedListView, the queryset of this view should contain Order instances that follow a condition so i try to apply filter in its get_queryset() class orderList(paginatedListView): template_name = "dashboard/reports.html" model = Order def get_queryset(self): qs = super(orderList,self).get_queryset().filter(Order_status=Order.ORDER_PLACED) return qs But this returns a error which says Cannot filter a query once a slice has been taken. I know why Django is throwing this error, one way I know how to make this work is just rewrite the whole code of paginatedListView in orderList and apply filter before pagination. But is there any other elegant way of doing it? -
How to filter model_set in django
Here is my part of template: {% for sitting in c.sittings %} {% if sittings.sit_date == sittings.shiftdate_set.all %} <p>Firstly it was scheduled on {{sitting.sit_date}}</p> {% endif %} {% endfor %} But this code return all the sitting dates not particularly equal to sit_date of Shiftdate model. I can't filter sit_date from shiftdate_set. I also tried to using following method in Sitting model: def get_shiftdate(self): return self.shiftdate_set.filter(shift_date=self.sit_date) and Using it in the above template as: {% for sitting in c.sittings %} {% if sittings.sit_date == sittings.get_shiftdate %} <p>Firstly it was scheduled on {{sitting.sit_date}}</p> {% endif %} {% endfor %} But still I am getting all the sitting dates not only related sitting dates. Could anybody help to figure out what I am doing wrong. -
How to copy queryset Django
I am trying to access queryset of ManyToManyField before and after saving in def save_related(self, request, form, *args, **kwargs) method. I want to compare them and get new objects, that were added to ManyToManyField. So, I am getting old queryset with: def save_related(self, request, form, * args, * * kwargs): obj = form.instance queryset_before = obj.translations.all() print(queryset_before) super(WordAdmin, self).save_related(request, form, * args, * * kwargs) print(queryset_before) But print(translations_before) outputs the new, updated queryset after calling super().save_related. So: How to copy queryset, so that saving will not affect it? Or is there a way to compare old and new values of ManyToManyField more properly? -
django: return Fields as different types than defined in database
In a django app, with an existing databse, I've used inspectdb to build a model: class Sensorparser(models.Model): """ a read-only implemenation to access the MeshliumDB """ id_wasp = models.TextField(blank=True, null=True) id_secret = models.TextField(blank=True, null=True) frame_type = models.IntegerField(blank=True, null=True) frame_number = models.IntegerField(blank=True, null=True) sensor = models.TextField(blank=True, null=True) value = models.TextField(blank=True, null=True) timestamp = models.DateTimeField() raw = models.TextField(blank=True, null=True) parser_type = models.IntegerField() def save(self, *args, **kwargs): return def delete(self, *args, **kwargs): return class Meta: managed = False db_table = 'sensorParser' I added the save and delete methods, because this should be a read-only model. This works great, but the thing is the database has defined (or at least inspectdb suggested) that id_wasp and id_secret and value are type TextField. This is correct, as they are in the database, but in my app I would like to treat them as type IntegerField. Is it okay to simply use those types of fields instead? E.G.: class Sensorparser(models.Model): ... id_wasp = models.IntegerField(blank=True, null=True) id_secret = models.InteferField(blank=True, null=True) ... id_value = models.FloatField(blank=True, null=True) I'm asking because I've done this, and it works, but I want to know if it is valid, or may cause me problems down the road. Thanks! -
django - update details using forms
For my django application, I have created signup and login pages. signup handles the signing up of a user with: full_name,user_email and password fields. Similarly, login logs the user in after authentication and the login.html has a logout button and associated view that handles logout with session variables. Now, after signing in I want to have another form that asks for more details like: postal_address, date_of_birth etc. (say 5 more fields) with a CREATE button that adds all these details to a separate table. When the user next logs in, he should see all his details printed out with an UPDATE button that will take him/her to the same form where he can change his details if he needs to. This means the previously created details should still appear in the textboxes and the user must be able to modify them. How would I go about achieving the above? I'm assuming the UPDATE button only shows up once the user's session starts? Any guidance, ideas or references to go about this would be much appreciated. -

Django select_related join model attributes with a single query

Upload images in Django trough Ajax without submitting entire form
I have 4 ModelForms and 1 form in the same template, I'm using the same <form> tag to all of them, so they are all part of the same form and when I submit it all the data will be sent.

This is how my template looks: When I press the button, (is a button type, not a submit) the image will be uploaded to the server and it's route will be saved to the database and then it's primary key will be sent trough Ajax in a json array.

Function call on individual field save in django
Say I have a model: class Workplace(models.Model): name = models.CharField(max_length=255) ... office_mail_id = models.EmailField(null=True, blank=True) What I want is whenever the value of email is changed and the object is saved, a function should be run which would save the value of that field to other models (say Emails) Now, this can be done in many ways like creating a custom save function which would call the email saving function or otherwise making a custom function and save emails through it: def set_email(self, email): self.office_mail_id = email self.save() # do whatever i want return What i want to know is that is there a simpler way to do this so that whenever i run company.office_mail_id = request.POST.get('email') company.save() in a view, the function may be run saving it to other models as i want The problem here is that I am not saving all fields individually but making a dictionary and saving all fields based on key and values like this as there are so many fields: for key in dictionary: setattr(workplace, key, dictionary[key]) workplace.save() What can be the best way to do it? -

If I take a print of answer its coming as False. Also if I change form.cleaned_data.['answer'] to False, it is well accepted. Where am I making a mistake?
