Django two projects, same database
I try to set up two projects, The first is a management project - it involves auth_user, sessions, writing to db. The second project is a "serve content" project, it only read from the db, uses no sessions, users.. It rely on db data created in the first project, but does not change it. The second project urls will be accessed very frequently. That's why I want to seperate the projects, with different subdomaons, and two apache instances, giving the second one more "power" (processes in wsgi deamon conf). So what should I share between the projects? Same settings? SECRET_KEY? Models? I assume I should also remove session app. Can I set django db to be in read only mode? -
Django filters. is_safe doesn't work
In my app teams/templatetags/teams_extras.py I have this filter from django import template register = template.Library() @register.filter(is_safe=True) def quote(text): return "&laquo; {} &raquo;".format(text) So I use it into my view teams/templates/teams/show.html {% extends './base.html' %} {% load static %} {% load teams_extras %} ... <b>Bio :</b> {{ team.biography|quote }} ... But this is the result on my page: &laquo; <p>The Miami Heat are an American professional basketball team based in Miami. The Heat compete in the National Basketball Association as a member of the league's Eastern Conference Southeast Division</p> &raquo; Why ? Thank you -

Using dynamic variable in Django Model.objects.filter()
I am facing issues with using dynamic variable after submitting form the in Model.objects.filter(). Added my source code below- user_check = UserForm(request.POST) if user_check.is_valid(): user_id = user_check['user_id'] #Submitted '9a26b3e5-1892-439b-b392-1779a043ca1a' get_user = User.objects.filter(id=user_id) num_of_user = get_user.count() If I use direct assignment i.e. user_id = '9a26b3e5-1892-439b-b392-1779a043ca1a' get_user = User.objects.filter(id=user_id) num_of_user = get_user.count() then I get 1 for num_of_user but id submitted through form submission always result 0. Also, after submitting the form then I was able to view the submitted user id back to my frontend template. Thanks in advance! -

django-autocomplete-light, widget attributes, no placeholder visible
I've implemented autocomplete in my form: related_groups = forms.ModelChoiceField( queryset=UserGroup.objects.all(), widget=autocomplete.ModelSelect2Multiple( url='groups-autocomplete', attrs={ 'data-placeholder': 'Autocomplete ...', 'data-minimum-input-length': 2, }, ) ) Generally, autosuggesting works but the placeholder and minimum input lenght don't (groups-autocomplete is my alias to my view).

Django - Preselect options in MultipleChoiceField
I have a class form that has the forms.MultipleChoiceField in it. I am able to render it and show all the choices to select / highlight, but what I want is the choices that get displayed to be pre-highlighted. so it is up to the user to either deselect the options or leave them as they are when they submit the form. Is there a way to do this ? Thanks -

Producing a list by summing results of 'values_list' in Django queryset
Through a Django queryset call, I'm generating a list of integer tuples: [(0,1),(0,2),(0,4),(5,8),.......] I instead need to generate a list which sums the two elements inside the tuple together, i.e. [1,2,4,13,.....] How can I accomplish that within the Django queryset query?

Virtual environment python causing Django.core not found error
I am currently experiencing problem with the virtual environment. Using virtual environment wrapper, I used 'workon' to be in that environment. In this enviornment there is a Python 2.7 in Scripts folder and when I run python, it is indeed running this python. When I run django-admin.py it returns the following error: Traceback (most recent call last): File "C:\Users\JOHN\Envs\courseva\Scripts\django-admin.py", line 2, in <module> from django.core import management ImportError: No module named django.core FYI, I installed django and it is within this Envs/courseva folder (Lib/site-packages folder) now. I was curious so I ran python and in the command I tried 'from django.core import management' and it is not throwing an error and I am really confused now. I was concerned with the default Python 2.7 in C: so I even changed the environment path but no use. Please help. -
Taking value from Timefield in a model and Using datetime operations on it.
I am make an appointment booking functionality in an app. For that, I have start and end time of two work shifts. Using values from those two fields, I would like to find total minutes in each shift and then divide it into half hour slots. The problem that I have is this : datetime library expects datetime objects to evaluate a timedelta but all I have are the TimeField. How do I convert TimeField to datetime.time value Below is the model : class ClinicMembershipAttribute(models.Model): DAY_CHOICES = ( ('Monday', 'Monday'), ('Tuesday', 'Tuesday'), ('Wednesday', 'Wednesday'), ('Thursday', 'Thursday'), ('Friday', 'Friday'), ('Saturday', 'Saturday'), ('Sunday', 'Sunday') ) clinicmembership = models.ForeignKey(ClinicMembership, null=True, blank=True) day = models.CharField(choices=DAY_CHOICES, null=True, blank=True, max_length=12) shift_one_start = models.TimeField(null=True, blank=True) shift_one_end = models.TimeField(null=True, blank=True) shift_two_start = models.TimeField(null=True, blank=True) shift_two_end = models.TimeField(null=True, blank=True) def get_appointment_status_string(self): first_shift_delta = (datetime.datetime.combine(datetime.date(1,1,1),self.shift_one_start) - datetime.datetime.combine(datetime.date(1,1,1), self.shift_one_end)).time() second_shift_delta = (datetime.datetime.combine(datetime.date(1,1,1),self.shift_two_start) - datetime.datetime.combine(datetime.date(1,1,1), self.shift_two_end)).time() first_shift_seconds = first_shift_delta.seconds() second_shift_seconds = second_shift_delta.seconds() def __str__(self): return self.day + " - '"+str(self.shift_one_start) +" - " + str(self.shift_one_end) + "', '" + str(self.shift_two_start) +" - " + str(self.shift_two_end) + "'" Error is in first_shift_delta and second_shift_delta. -
Parameter order for unittest.TestCase.assertEqual
Is it assertEqual(actual, expected) or assertEqual(expected, actual)? On the one hand I'm seeing lots of code using assertEqual(actual, expected). This includes examples in the unittest docs and examples in the Django docs. However, this test assertEqual('foo', 'bar') is giving me the output - foo + bar Which happens to be the same as for a PHPUnit test with assertEquals( 'foo', 'bar' ); -'foo' +'bar' And PHPUnit has $expected as first parameter, followed by $actual. This diff is also what I'd expect for expected, actual. So is all this Python code I'm seeing doing it wrong? I checked the definition of the unittest method, though that has the extremely helpful first, second parameter names. -

Django Foreign Key duplicate column
I have a prexisting MySQL database that contains a table with a foreign key to another the table. I used inspectdb in Django 1.10 to form the following models from it : class Contested(models.Model): candidate = models.ForeignKey('Candidate',default=None) district = models.CharField(max_length=10) state = models.CharField(max_length=45) num_votes = models.IntegerField() per_votes = models.DecimalField(max_digits=3, decimal_places=2) incumbent = models.IntegerField() year = models.IntegerField() class Meta: managed = False db_table = 'contested' unique_together =(("district","state","year","candidate","num_votes"),) class Candidate(models.Model): first_name = models.CharField(max_length=45, blank=True, null=True) last_name = models.CharField(max_length=45) class Meta: managed = False db_table = 'candidate' However when I attempt to migrate I get django.db.utils.OperationalError: (1060, "Duplicate column name 'candidate_id'") I believe this is because I already have a foreign key relation in my db ( column candidate_id is already in the Contested table), yet Django is attempting to construct the relation itself by adding column candidate_id to the Contested table (although managed is False). Is there a way to for Django to recognize the Foreign key relation already exists? -
