Why do static files won't load in the web app?
So I've seen a lot of tutorials here explaining what to do, but no matter what I change the static files won't seem to load. This is what my files are looking like atm settings.py STATIC_URL = '/static/' STATIC_ROOT = os.path.join(BASE_DIR, 'static') STATICFILES_DIRS = [os.path.join(PROJECT_ROOT, "static"),''] job_app/urls.py urlpatterns = [ path('', main, name='index'), ] + static(settings.STATIC_URL, document_root=settings.STATIC_ROOT) index.html <!DOCTYPE html> <html lang="en"> <head> <title>JobPortal - Free Bootstrap 4 Template by Colorlib</title> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no"> {% load static %} <link href="https://fonts.googleapis.com/css?family=Nunito+Sans:200,300,400,600,700,800,900" rel="stylesheet"> <link rel="stylesheet" href="{% static 'css/open-iconic-bootstrap.min.css' %}"> <link rel="stylesheet" href="{% static 'css/animate.css' %}"> <link rel="stylesheet" href="{% static 'css/owl.carousel.min.css' %}"> <link rel="stylesheet" href="{% static 'css/owl.theme.default.min.css' %}"> <link rel="stylesheet" href="{% static 'css/magnific-popup.css' %}"> <link rel="stylesheet" href="{% static 'css/aos.css' %}"> <link rel="stylesheet" href="{% static 'css/ionicons.min.css' %}"> <link rel="stylesheet" href="{% static 'css/bootstrap-datepicker.css' %}"> <link rel="stylesheet" href="{% static 'css/jquery.timepicker.css' %}"> <link rel="stylesheet" href="{% static 'css/flaticon.css' %}"> <link rel="stylesheet" href="{% static 'css/icomoon.css' %}"> <link rel="stylesheet" href="{% static 'css/style.css' %}"> </head> <body> jobber/urls.py urlpatterns = [ path('admin/', admin.site.urls), path('', include('job_app.urls')) ] + static(settings.STATIC_URL, document_root=settings.STATIC_ROOT) -

UNIQUE constraint failed on adding a new model field in django
When i want to add a new field called slug to my Post model in Djnago, the migrate command will raise UNIQUE constraint failed: new__chat_post.slug After that i remove that field from my model but the problem still exists. why?? and how to resolve this problem without deleting my whole table data?? The database is sqlite3 and the Django version is 2.2 . thanks.

How to properly use FieldKeys to verify data in separate models?
I'm making a form that has a few fields in my model. The first field of this model, called EmployeeWorkAreaLog is Employee#/adp number. I have another model, called Salesman that is used as the main database with all the employees, and has each person's info, along with their employee #. What I was trying to achieve is that the form doesn't submit if the employee # is not valid, meaning is not currently in Salesman model. Below is what I tried to do, but I noticed that this is tying the Employee # to the auto-generated ID in the database, not the adp_number. I tried to make some changes with how the relation is but every time I ended up having to modify the Salesman model, which I cannot do, because it said something about the field being unique. Note that, in my EmployeeWorkAreaLog, the same employee can have multiple entries, so I don't know if that's what might be causing this. How could I approach this without changing Salesman? And, secondary question, not as crucial, is there any way that, upon submission, I can copy the slsmn_name from Salesman into the corresponding employee_name? I had created the get_employee_name() function, … -
upgrading Django and Python versions, problem with default value for FloatField set to string
In a model using Django 1.8 and Python 2.7 we had a migration that accidentally set the default value for a FloatField to an empty string (default=''), which Django appears to have interpreted as a bytes-string: class Migration(migrations.Migration): dependencies = [ ('reo', '0030_merge'), ] operations = [ migrations.CreateModel( name='ProfileModel', fields=[ ('id', models.AutoField(verbose_name='ID', serialize=False, auto_created=True, primary_key=True)), ('pre_setup_scenario_seconds', models.FloatField(default=b'', null=True)), ], ), ] After upgading to Django 2.2 and Python 3.6, Django gives the warning with manage.py migrate that there are un-migrated changes. After changing the default value from '' to None and running manage.py makemigrations we get: operations = [ migrations.AlterField( model_name='profilemodel', name='pre_setup_scenario_seconds', field=models.FloatField(default=None, null=True), ), ] Then running manage.py migrate yields: nlaws-> python manage.py migrate Operations to perform: Apply all migrations: auth, contenttypes, django_celery_results, proforma, reo, resilience_stats, sessions, summary, tastypie Running migrations: Applying reo.0050_auto_20191030_1738...Traceback (most recent call last): File "manage.py", line 10, in <module> execute_from_command_line(sys.argv) File "/Users/nlaws/.virtualenv/api/lib/python3.6/site-packages/django/core/management/__init__.py", line 381, in execute_from_command_line utility.execute() File "/Users/nlaws/.virtualenv/api/lib/python3.6/site-packages/django/core/management/__init__.py", line 375, in execute self.fetch_command(subcommand).run_from_argv(self.argv) File "/Users/nlaws/.virtualenv/api/lib/python3.6/site-packages/django/core/management/base.py", line 323, in run_from_argv self.execute(*args, **cmd_options) File "/Users/nlaws/.virtualenv/api/lib/python3.6/site-packages/django/core/management/base.py", line 364, in execute output = self.handle(*args, **options) File "/Users/nlaws/.virtualenv/api/lib/python3.6/site-packages/django/core/management/base.py", line 83, in wrapped res = handle_func(*args, **kwargs) File "/Users/nlaws/.virtualenv/api/lib/python3.6/site-packages/django/core/management/commands/migrate.py", line 234, in handle fake_initial=fake_initial, File "/Users/nlaws/.virtualenv/api/lib/python3.6/site-packages/django/db/migrations/executor.py", line 117, in migrate … -

Django request timeout for some static files when running manage.py test package.to.unit.test
Context: We run Cypress tests which use instances of our application started using manage.py test package.test.suite. The test fixtures and environment are all set up using a class extended from django.contrib.staticfiles.testing.StaticLiveServerTestCase. A unit test/method is added to the extended class which invokes Cypress as a subprocess to run the tests and asserts against the exit code of the subprocess. Versions: Python: 3.6.8 Django: 2.2.3 macOS: Mojave 10.14.6 The problem: This worked well until yesterday when I updated Cypress via npm. Now when I start a server using manage.py test some.test.suite the server will fail to serve all of the static resources requested by the browser. Specifically, it almost always fails to serve some .woff fonts and a random javascript file or two. The rest of the files are served but those 5 or 6 which the browser never receives a response for. Eventually I'll get a ConnectionResetError: [Errno 54] Connection reset by peer error (stack trace below) in the terminal. Additionally, if I enable the cache in my browser and attempt a few refreshes things will work fine, almost as if theres a limit to the number of files that can be served at once and once some files are … -
Django-Channels with 2 applications
I'm trying to make an example to test if it is possible to have 2 independent django apps connected to the same channel from django-channels. So far, I was able to make an example running on one machine and 2 other machines being able to access the first via a client. But the goal is to be able to connect separate applications in a single channel to communicate. Is that possible? If not, do you know an alternative? Note: I'm also using redis, if that helps. Thank you! -
Selenium keeps a cache?
I have a more complicate question but I'm trying to isolate the problem to avoid confusion. I'm testing a page using selenium. In this page there are two javascript external scripts. If you go there manually the page is working correctly but using selenium one of the javascript isn't loaded: The script from “http://localhost:55234/static/js/common.js” was loaded even though its MIME type (“text/html”) is not a valid JavaScript MIME type. 2 add-name Loading failed for the <script> with source “http://localhost:55234/static/js/common.js”. Checking the source (right click => view page source) gives me correctly the template with this two lines (and the others, off course): [...] <!-- load global javascript --> <script type='text/javascript' src="/static/js/common.js"></script> <!-- load app javascript --> <script type='text/javascript' src="/static/lists/js/lists.js"></script> [...] the src are clickable. Cliking the first one reload the source page without the line three and four, so without this lines: <!-- load app javascript --> <script type='text/javascript' src="/static/lists/js/lists.js"></script> Cliking the second one (lists.js) gives the javascript code. But! But this code looks an (very) old version of my code. Many days old (isn't too long to be cached?). At that time all the code was in one javascript file (lists.js) and the other one (common.js) didn't existed so … -

Using only gunicorn, django, and whitenoise how do I serve media?
I have my website finally working properly, but media files aren't served when debug = False what should I do? I've went through hell trying to make it work with nginx following this tutorial but it kept breaking and not serving static among other things, so I went with pure gunicorn and whitenoise. I really am not an expert at deploying, only development. Please help. Security isn't a problem with media files because only the admin can upload them, not end-users. Specifically I need to know if it's the end of the world leaving debug = True just for media files. Or if there's an easy way to serve them with debug = False. -

Django - How to make a ForeignKey dropdown into a textbox?
I have a form that has a field which is a ForeignKey since it makes sure that the ID # being entered is one that exists in the database. After making it be a ForeignKey, it changed my field to look like a dropdown in the form as shown below, that contains a bunch of options called "Salesman object ('a number')", instead of it being a text box like it was before. The user is supposed to be able to enter their "adp" number and it should only allow numbers in salesman. Before I had made this change, I just had the adp_number under fields in forms.py, and not as a ForeignKey, which made me not be able to cross check with the Salesman model which contains all the valid adp_number's. I tried following this Django: using ForeignKeyRawIdWidget outside of admin forms since I'm not using admin either, but once I made the field into a widget it just stopped showing on my page altogether and I'm not sure what needs to be changed. forms.py class WarehouseForm(AppsModelForm): class Meta: model = EmployeeWorkAreaLog widgets = { 'adp_number': ForeignKeyRawIdWidget(EmployeeWorkAreaLog._meta.get_field('adp_number').remote_field, site), } fields = ('work_area', 'station_number') models.py class EmployeeWorkAreaLog(models.Model): employee_name = models.CharField(max_length=25) adp_number … -

How should images used in jquery-ui be loaded in django admin?
