Django migrations - default entries (inserting rows in tables as part of migration)
Background: I'm dealing with quite complex django application and I'm looking for a way to make my life a little bit easier. One of the models (tables) serves as source of "options" for most "select lists" in the system (simple field <-> dictionary construct). It should always be populated with the default values and/or extenden when the there are new entries provided with a new version of the system. I manage it all now manually so: I run migrations for the main app Unload the dictionary tables from the dev enviroment Insert them manually into the enviroment I'm currently upgrading I migrate the rest of the apps which may contain refferences to the dictionary tables All of this because of default values provided in ForeignKeys. Actual Question: Is it possible to add table entries (table content) to the makemigrations process for particular tables?? -
In django, values(*field) doesn't give all values of ForeignKey field with sliced queryset
self.model.objects.filter(pk=2)[:1].values(*fields) self.model.objects.filter(pk=2).values(*fields) Why can't the first one return all values of Foreign key field, but the second one works as expectation? -
how to access/modify django model fields before validating its form in Listview
I have a model Course that has the following attr: class Course(models.Model): user= models.ForeignKey( User, on_delete=models.CASCADE, ) # email= models.EmailField(default=user.email) courseName= models.CharField(max_length=20, blank=False) class Meta: unique_together= ('user','courseName',) def __str__(self): return self.courseName I have created a form where I want the user to enter just the courseName and after they POST it, I will add the requested user in the model as well. This is my form which is getting passed on to the template via my ListView forms.py class CourseForm(forms.ModelForm): class Meta: model= Course fields = ['courseName'] **Here is my views.py where I am struggling with ** class CoursesListView(ListView, FormMixin): model = Course form_class = CourseForm template_name = "userApp/courseList.html" def get_queryset(self): return Course.objects.filter(user__exact=self.request.user) def get_context_data(self,*args,**kwargs): context= super(CoursesListView,self).get_context_data(*args, **kwargs) context['courseForm'] = self.form_class return context def post(self,request, *args, **kwargs): form = self.form_class(request.POST) user = User.objects.get(username__exact=self.request.user) **I want to add the user to my model.user field here** return self.get(redirect, *args, **kwargs) def get(self,request, *args, **kwargs): self.object=None self.form = self.get_form(self.form_class) return ListView.get(self, request, *args, **kwargs) So basically my question is how can I add the user in my model before calling form.is_valid(). -
Forbidden access, CSRF token missing or incorrect
I'm trying to create an ajax function, however I have two issues. Which I think is odd since I'm following another application I have where it works just fine. This is my function. What I'd like use is {% url 'kar:shoppingCartAdd' %} instead of a hardcoded URL. But it'll give me a 404 not found. The hard coded URL will give this from the console. Forbidden (CSRF token missing or incorrect.): /Karklude/shoppingCartAdd/5 [27/Dec/2016 09:35:32] "POST /Karklude/shoppingCartAdd/5 HTTP/1.1" 403 2274 $(".addToCart").click(function() { $.ajax({ url : "shoppingCartAdd/", type : "POST", data : { csrfmiddlewaretoken : '{{ csrf_token }}', 'number' : 5, }, success : function(data) { console.log(data); }, error : function() { console.log('error'); } }); }); url and view function urlpatterns = [ url(r'^shoppingCartAdd/$', views.shoppingCartAdd, name='shoppingCartAdd') ] def shoppingCartAdd(request, number): print(number) //Do some magic return JsonResponse({}) -
Django: static image file should be stored in git repository when using AWS cloudfront and S3?
I developed my Django project with AWS cloudfront and S3. I wonder whether static image file(not media file) should be stored in git repository. I think that if I run collectstatic --settings="production.settings all static files seems to be uploaded on my S3. If so, I think that I don't need to store all static image files in git repository. Am I right? -
Dynamically import url in Django gives 'str' object is not callable
I'm trying to write some code to dynamically import "plugin-like" application in my django project. I'm using Django 1.10 I subclassed the django.apps.AppConfig class and used it to mark the plugins: from django.apps import AppConfig class AutomationAppConfig(AppConfig): def get_url(self): return self.name then, in my project main urls.py I added this code after the main "static" urlpatterns initializazion: ... from slae.util import AutomationAppConfig from django.apps import apps for module in iter(apps.get_app_configs()): if isinstance(module, AutomationAppConfig): url = module.get_url() urlpatterns.append(url(r'^%s/' % url, include('%s.urls' % module.name), name = module.name)) but it gives the following error when the server (re)loads ...

How to set default css classes for all built-in form widgets in Django
Short version: is it possible to define a set of default css classes that Django should use whenever rendering a form ? Long version: The context is as follows: I would like to use the css classes defined in the w3.css framework for all my forms (http://www.w3schools.com/w3css/default.asp). I have seen that it is possible to do that in Django at form class definition or at form rendering, but it requires in both cases an explicit declaration of all the form fields. That means that I loose all the benefit of automatic form generation for ModelForms. I would like something as follows instead: Define somewhere (e.g. in the settings file) a default mapping between form fields / widgets and css classes, e.g. 'textinput': 'my_default_css_class_for_text_inputs' By default, for all automatic generation and rendering of forms, the default css classes defined in (1) are used, with no or minimal modification of the existing form classes For specific forms, I can overload the defaults with other values As far as I've understood, such behaviour is not possible in django. The crispy-forms package seems to go in that direction, but it seems to do much more than just that, and I am not sure that … -

Pass GET parameters through django's render() shortcut
I have a date filter that I am passing through several django views: views.py def event_list(request): date_query = request.GET.get("date", str(default_event_date())) d = datetime.strptime(date_query, "%Y-%m-%d").date() # do stuff... return render(request, "events/event_list.html", context) But I would like to carry forward the GET parameters through the render(). I've found this answer for how to do this using reverse(), but render() doesn't take a url directly. I suspect I need to add it back in to the request that is passed, but I'm not sure how to do this. -
Django multi-table inheritance affects the 'pk' property of the child model
I discovered a possible issue with "multilayer" model inheritance in Django. I take advantage of multi-table inheritance by defining a base model class, subclassing it and sometimes further subclassing the resulting model. Example: settings.py (diff from Django 1.8 default): ROOT_URLCONF = 'my_app.urls' WSGI_APPLICATION = 'my_app.wsgi.application' DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'dj_db', 'USER': 'happy', 'PASSWORD': 'camper', 'HOST': '127.0.0.1', } } TIME_ZONE = 'Pacific/Auckland' INSTALLED_APPS += ( 'my_app', ) models.py: from django.db import models from django.contrib.auth.models import User from django.utils.translation import ugettext_lazy as _ import uuid class Base(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) date_changed = models.DateTimeField(_('added/modified'), auto_now=True, editable=False) enabled = models.BooleanField(_('enabled'), default=True) class MyMate(Base): user = models.ForeignKey(User, editable=False) # fields for first and last names, etc. nick = models.CharField(_("Nick"), max_length=75, editable=True, blank=False, unique=True, help_text=_("Mate's nickname")) def __unicode__(self): return unicode(self.nick).encode('utf-8') class Meta: verbose_name = _('Mate') verbose_name_plural = _('Mates') class ReBase(Base): place = models.CharField(max_length=260, editable=False) def __unicode__(self): return unicode(self.place).encode('utf-8') class MyWorkmate(ReBase): class Meta: verbose_name = _('Workmate') verbose_name_plural = _('Workmates') class MyClassmate(ReBase): class Meta: verbose_name = _('Classmate') verbose_name_plural = _('Classmates') Ignore the possible performance problems of such a solution (this is just an example). admin.py: from django.contrib import admin from django.utils.translation import ugettext_lazy as _ from my_app.models import MyMate, MyWorkmate @admin.register(MyMate) class … -

Django: how can I check whether any one of forms, stackedInlineforms has changed in admin?
admin.py class ItemInline(AdminImageMixin, admin.StackedInline): model = Item extra = 0 fields = ( 'variation', 'ordered_original_unit_price', 'width', 'height', 'quantity', 'ordered_sale_percent', 'total_price', 'image1', 'image2', ) form = ItemImageAdminForm class PaymentInline(admin.StackedInline): model = Payment extra = 0 fields = ( 'pay_method', 'bank', 'account_owner', 'due_date', 'cash_receipt', 'cash_receipt_for', 'cash_receipt_method', 'cash_receipt_of' ) form = PaymentAdminForm class WorkScheduleInline(admin.StackedInline): model = WorkSchedule extra = 0 min_num = 1 fields = ( 'work_date', 'work_time', ) form = WorkScheduleAdminForm class OrderAdmin(BaseAdmin): class Media: js = ( 'https://code.jquery.com/jquery-2.2.3.min.js', 'js/order_admin.js', ) inlines = [WorkScheduleInline, PaymentInline, ItemInline, ] form = OrderAdminForm As you can see above, OrderAdmin has three inlineAdmins which has its own custom form. What I want to do is : If any of field change detected among the forms, send message to client. What I've tried is to insert has_change() method inside of each form's is_valid() method and send message according to its result. It might seem look good, but problem is that if there were changes in field of each 4 forms, then it sends four messages instead of only one message. How can I deal with it so that I do only one task(send message) if changes detected? -
