How to use django on two databases
I have a legacy Django project with a legacy database. That project uses django.contrib.auth.User as the user model. Now I need to write a new Django project and that app has to get access to the legacy database. The problem is that my new Django project also needs a User object. So how do I route django.contrib.auth.user models into the correct database? Another possible way to do this: is it possible to "bootstrap" a Django app for use inside another project? So if I have a legacy Django app with legacy settings.py, and I want to use the Django model functionality inside a new Django project with new settings.py (and it has its own apps), is there a way to do this? -

How to create Prefetch queryset based on parent queryset in django
Here is the scenario, a project model which contains multiple bids. `Class Project(models.Model): user = models.ForeignKey() Class Bid(models.Model): project = models.ForeignKey(Project, related_name='bids')` When we are querying projects, we want to prefetch bids for projects. Project.objects.filter(whatever condition).prefetch_related( Prefetch('bids', queryset=Bid.objects.all()) ) Here we only want to fetch the bids that belongs to the filtered projects, but not all the bids, how can we specify that? I am expecting something like queryset=Bid.objects.filter(project=project?)... Thanks. -
Type Error in get_wsgi_application() in Django 2.x with python3
I am migrating a web application from Django 1.9 to 2.0.2. The code is import os import sys path = '/mypath' if path not in sys.path: sys.path.append(path) os.environ.setdefault("DJANGO_SETTINGS_MODULE", "Myapplication.settings") from django.core.wsgi import get_wsgi_application application = get_wsgi_application() However, if I try to execute this, I get an error: File "/home/.../wsgi.py", line 29, in <module> application = get_wsgi_application() File "/home/.../virtual/lagerthree/lib/python3.5/site-packages/django/core/wsgi.py", line 13, in get_wsgi_application return WSGIHandler() File "/home/.../lagerthree/lib/python3.5/site-packages/django/core/handlers/wsgi.py", line 140, in __init__ self.load_middleware() File "/home/.../virtual/lagerthree/lib/python3.5/site-packages/django/core/handlers/base.py", line 39, in load_middleware mw_instance = middleware(handler) TypeError: object() takes no parameters According to StackExchange and other sites, the cause of this error is the deprecation of certain things from 1.x to 2.x and the solution is the MiddlewareMixin which should be used like this: class FOOMiddleware(MiddlewareMixin): ...

( in which file ) I'm a beginner at this so if there are any mistakes please let me know. -
I need advice on how to implement a checkbox in Django
I am trying to create a way that a student can enroll to a teacher's course. I added a boolean field to my StudentData model and from there I added a many-to-many field to my Course model. Each of my course page is a generated slug page and there all students are listed. I want that near each student a checkbox will be shown. And if teacher selects more students and presses Enroll button, only those students can view the course. Now, the template conditionals I can do them myself, but I am stuck on updating data the right way using the checkbox. This is the boilerplate: <ul> {% for student in students %} <br> <br> {{ student.name }} {{ student.surname }}<input type='checkbox' {% ifequal value 0 %}checked{% endifequal %}> 0 <br> <br> {% endfor %} </ul> <div class="row"> <div class="col-md-4"> <div class="pagination"> <span class="step-links"> {% if students.has_previous %} <a href="?page=1">&laquo; first</a> <a href="?page={{ students.previous_page_number }}">previous</a> {% endif %} <span class="current"> {{ students.number }} </span> {% if students.has_next %} <a href="?page={{ students.next_page_number }}">next</a> <a href="?page={{ students.paginator.num_pages }}">last &raquo;</a> {% endif %} </span> </div> </div> <div class="col-md-4"> <button class="btn-success">Enroll</button> </div> </div> class StudentDataForm(forms.ModelForm): enrolled = forms.BooleanField() def __init__(self): if self.checked: self.fields['enrolled'].initial … -

Django: Querying M2M table after object creation returns empty array
I'm using a Django signal to run a block of code after a model saves using post_save. The signal receiver in post_save gets an instance of the object sends it to a method for some processing before the instance is sent to a third party via network. One of my models, foo, has a many-to-many relation with another model, bar, and I need to add an array named bar_id that contains ids of each bar before I send foo to the third party. This configuration works when updating a foo instance however when I create a new instance of foo and I query for its relations (see the troublesome query in the Add Bar's ID to Foo and send it to third party section, the query is returning an empty query set even though the relation exists in the database. This exact same query returns a query set if I update the same model moments later. Any ideas of why this may be happening? Here's the code: Register the signal from django.apps import AppConfig class FooConfig(AppConfig): name = 'foo' def ready(self): import foo.signals Signal Code from django.dispatch import receiver from django.db.models.signals import post_save from django.conf import settings from django.db.models import … -

context and dictionaries python Django
So I have the following code: views.py: def topics(request): """Show all topics""" topics = Topic.objects.order_by('date_added') context = {'topics': topics} return render(request, 'learning_logs/topics.html', context) return render(request, 'learning_logs/topic.html', context) I understand that I am querying the database and sorting the data by date then storing that data in the topics variable. My first question is, is the topics variable storing the data as a list? (assuming multiple entries). If so when I have the following code in my html file topics.html: <ul> {% for topic in topics %} <li>{{ topic }}</li> {% empty %} <li>No topics have been added yet.</li> {% endfor %} </ul> why do I need pass the data stored in topics into a context dictionary for topics.html to loop through and display the data? why not loop through the topics variable itself? I'm just confused on the use of "contexts" Thanks for the help in advance. -
Django Model.objects.all() returns unexpected empty QuerySet
I have some problem while trying to use a MySQL database with Django. The database contains a table named items. This database is imported from a development system to a production system. This database is the second database in addition to an existing SQLite databased used by other teams. There had been an error message about no such table, but I was able to solve it with this question. It assume that there are no migration errors. The MySQL database works fine in the development system (tested using python manage.py shell), but it doesn't work in the production system (tested the same way.) I tested the import with: $ python manage.py shell >> from project.models import Item >> Item.objects.all() <QuerySet []> I created the models.py file with: $ python manage.py inspectdb > models.py I verified that the database and the table items actually contains records. (Although some fields are stored as unicode text, if that makes any difference to the situation.) I am using Django 2.0.2 with Python 3.6.3. -

How to show a update form while keeping the original data in Django?
I'm using Django Forms to do some updating work.For example,I write a FilmForm to present a film information form: class FilmForm(forms.Form): name = forms.CharField() director = forms.CharField() release_year = forms.DateField() ......(many other infos) And I create and save a model instance using the form.Next time I want to modify only one info,like 'director',and update the model info using the FilmForm. def FilmUpdate(request,pk): if request.method == 'POST': ... else: form = FilmForm() return render(request,'film_update.html', {'form':form}) but when the form show up,the html inputs are all blank,and have to input all the original data again while the only item I want modify is just 'director'.So how to present the update form with the original data keeping? -

proper way to set up many to many relation where intermediary field has foreign keys django
I have a custom user field and a permissions field in a django app. The documentation says the following: https://docs.djangoproject.com/en/2.0/ref/models/fields/#django.db.models.ManyToManyField that we are to use the manytomany through method.

django sqlite3 URIs not supported
Odd situation. Django 2.x in its features for sqlite3 drive turns on uri support. It seems to only be a problem seen in python 3. On machines with older version of sqlite, in my case 3.6.20, the problem of URIs not supported does not arise with exactly the same virtualenv and codebase. On machine with sqtlite3 --version showing 3.7.17 it does arise. The funny thing is the feature is only supported in sqlite3 after 3.7.7 or so from what I read. So apparently django sees it is supported but it really isn't at the level of the internal sqlite3 drivers in python?
