How to change the background color of an input field of a Django form if it contains errors
I'm trying to code a form with fields that, if a user inputs data that doesn't pass the validation of the form, change their background colors from the default white to lightcoral. Here is a fragment of the HTML file that contains the form itself: <div id="div_formbox"> <form method="post" id="form_appointments"> {% csrf_token %} {{ form.non_field_errors }} <div class="input_group"> <div class="input_field {% if form.name.errors %}error{% endif %}"> {{ form.name}} </div> <div class="input_field {% if form.last_name.errors %}error{% endif %}"> {{ form.last_name }} </div> <div class="input_field {% if form.email.errors %}error{% endif %}"> {{ form.email }} </div> </div> <button type="submit">Send</button> </form> </div> And here is the part of the CSS file where I try to apply the color change to the input fields with errors: .error { background-color: lightcoral; } As you can see, I'm using Django tags to change the class of the form fields with errors from "input_field" to "error". Next, in the CSS file, I reference the "error" class to apply the styling I want. But it doesn't work. I've tried a bunch of variations but none have worked. I'm out of ideas. -
Celery server not terminating immediately when using prefork and without pool line command
I'm working on a django project with celery and redis installed. When I run the Celery server as 'celery -A main_proj -l debug -P solo' or 'celery -A main_proj -l debug -P threads', I can terminate them just fine by just pressing CTRL-C once or twice for warm/cold shutdown. However, when I run Celery as 'celery -A main_proj -l debug' and 'celery -A main_proj -l debug -P prefork', whenever I try to terminate them, it just get stuck at Worker: Stopping Pool. No matter how long I wait, it stays like that until I decide to terminate it with taskkill. I'm fine with the first two alternatives but I want to know why the latter options don't finish quickly. This is the code I have for my celery app: from __future__ import absolute_import, unicode_literals import os from celery.schedules import crontab from celery import Celery os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'main_proj.settings') app = Celery('main_proj') app.config_from_object('django.conf:settings', namespace='CELERY') app.autodiscover_tasks() Additionally, withing the settings.py file I set the CELERY_BROKER_URL with a redis URL that I get from Railway and I have the following code within the init file for the main_proj folder: from .celery import app as celery_app __all__ = ('celery_app',) This is what always happens whenever I … -
subdomain routing in django application
I have a django project that's hosted on a custom domain (e.g. mydomain.com). I have "app" app. For example, in development, requests looked like mydomain.com/app/dashboard. However, I wanted to use a subdomain instead so that my entire app is hosted on the subdomain app.mydomain.com and requests to mydomain.com/app/dashboard would route to app.mydomain.com/dashboard. I am using Nginx to handle this but I'm running into a few problems.

Best method to model django database using through table to access associations by date
Looking for advice on a tidy solution for accessing The end result I am looking for is the following report: cast, start_date, wire, winch I currently run a script when a cast object is submitted via form to get the active wire associated with the cast, and save it in the 'wire' foreign key field. The active wire is accessed in the script through property tags. Technically this information is retained in the database through a series of models associating a cast with a wire (Cast-DrumLocation-WireDrum), and the date fields that store when the events occurred. These events update the association between cast and wire. Is the way I modelled this a proper solution?, or is there another solutions where the wire foreign key does not need to be stored as a field in the cast model. class Cast(models.Model): id = models.AutoField(db_column='Id', primary_key=True) startdate = models.DateTimeField(db_column='StartDate') enddate = models.DateTimeField(db_column='EndDate') wire = models.ForeignKey('Wire', models.DO_NOTHING, db_column='WireId') winch = models.ForeignKey('Winch', models.DO_NOTHING, db_column='WinchId') class Drum(models.Model): id = models.AutoField(db_column='Id', primary_key=True\) location = models.ManyToManyField(Location, through='DrumLocation', related_name='active_location') material = models.TextField(db_column='Material') wiretype = models.TextField(db_column='WireType') class Winch(models.Model): id = models.AutoField(db_column='Id', primary_key=True) name = models.TextField(db_column='Name') drums = models.ManyToManyField(Drum, through='Drumlocation', related_name='active_drum') class Wire(models.Model): id = models.AutoField(db_column='Id', primary_key=True) nsfid = models.TextField(db_column='NsfId') drums … -

Best way for grouping models by two week periods and tie them to a data entry?
I am working on a project that is based on a two week time period. I have a model with a start_date and end_date as seen below: class CreateNewTimesheet(models.Model): employee = models.ForeignKey(Employee, on_delete=models.CASCADE) start_date = models.DateField(_("Start Date")) end_date = models.DateField(_("End Date")) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) I want to be able to add another line or something that groups the start_date and end_date. Dates: 03/06/2024 - 03/16/2024 And group or tie that to "week 1". The purpose behind this is to create a timesheet based on a two week time period. I need to be able to group the timesheets by a two week period and tie them to that specific group. All of the Timesheets need to be stored. After start_date and end_date are entered I need them to be tied to week one. I was thinking about adding another line to the CreateNew model and then tie that to week one. And then each start_date and end_date are entered, a new "week" is entered for each new start_date and end_date is created. Should that be based off of created_at entry? Should each week be grouped by a new url? I am honestly stuck at this point about … -

I'm just starting with django, and when I put {% load static %} in the html it doesn't complete it, that is, it doesn't take it as code, I need helpenter image description here I tried importing it through a link, adding a general folder but I don't know what happens -
Could not deserialize class 'Functional'
I did transfer learning to VGG16 model in order to classify images to cat or dog and here is portion of the code snippet : prediction_layer = tf.keras.layers.Dense(1) prediction_batch = prediction_layer(feature_batch_average) def manual_preprocess_input(x, data_format=None): if data_format is None: data_format = tf.keras.backend.image_data_format() if data_format == 'channels_first': # If channels are first, move them to the last dimension x = tf.transpose(x, perm=[0, 2, 3, 1]) # Mean subtraction (ImageNet means in BGR order) mean = [103.939, 116.779, 123.68] x = x - tf.constant(mean, dtype=x.dtype) # Zero-centering by subtracting 127.5 x = x / 127.5 return x inputs = tf.keras.Input(shape=(224, 224, 3)) x = data_augmentation(inputs) x = manual_preprocess_input( x ) x = base_model(x, training=False) x = global_average_layer(x) x = tf.keras.layers.Dropout(0.2)(x) outputs = prediction_layer(x) model = tf.keras.Model(inputs, outputs) and here is the view code where I loaded my model : then I saved it using model.save('my_model.keras'), then I loaded in a django view but the problem is whenever I load it and make post request to the view, in the line where I load the model I encounter this error : def testSkinCancer(request): model = tf.keras.models.load_model( os.getcwd()+r'\media\my_model.keras', safe_mode=False) print(">>> model loaded") if not request.FILES: return HttpResponseBadRequest(json.dumps({'error': 'No image uploaded'})) # Access the uploaded image …
