The solution works great except the part that the webpage contains images which do not show up in the pdf and i get an error Warning: Failed to load file:///media/images/main/logo.jpg (ignore) I'm currently using from_string method as follows pdfkit.from_string(msg_html, 'testing123.pdf') #msg_html contains html string with images -
Django TestCase: GET request should return 404 but return 200 in my test...?
I have a pdf function that print a pdf resume for example, this function is called with url /randomization/pdf/?patient=CIV-TR-001&medicament=8&type=1 if GET parameters are missing or not valid, it return a 404 or 500 error and it is the correct behavior I want to make a test for that but even if I pass empty 'patient' in my test, it always return status_code=200 (/randomization/pdf/?patient=&medicament=8&type=1) wherease when I call this url in my app, I am correctly redirected to my 404 page...

How to Delete or Ignore serializer.data object in serializer.py?
I need to delete serializer.data object in serializer, because i'm having some record in my table. But the entire record details is present in other microservice, Once someone called my api i need to call that service to get the data. But if the record is empty, i need to ignore this object. I can do this view, but it's possible to do in Serializer.py. Check the reference code: class CourseSerializer(serializers.ModelSerializer): user = serializers.SerializerMethodField() def get_user(self, obj): token = self.context['request'].META['HTTP_TOKEN'] username = get_user_details_from_id(str(obj['user']), token, name=1) if username: return username else: obj = {} class Meta: model = Course fields = ('user', 'total_score') I want to ignore the record in SerializerMethodfield if the username is empty -
Is it possible to have default values of TextFields refer to txt files?
I am building a basic system that allows users to send templated emails in Django. I have a field in my email model that provides the content for the email: class Email(models.Model): message = models.TextField(_("Message"), blank=True) I want to specify default content, however the message itself could be quite long. Is there any way to have the default value refer to a text file (or any file) rather than have this in the model itself? E.g. class Email(models.Model): message = models.TextField(_("Message"), blank=True, default='mytextfile.txt') Is much better than class Email(models.Model): message = models.TextField(_("Message"), blank=True, default='"Sed ut perspiciatis unde omnis iste natus error sit voluptatem accusantium doloremque laudantium, totam rem aperiam, eaque ipsa ab illo inventore veritatis et quasi architecto beatae vitae dicta sunt explicabo.

Django nested objects, different serializers GET and POST
this is a follow-up to this question I had here. I can now POST a new AP object using user Primary Key and after commenting this line in the AP serializer user = UserIndexSerializer(): Postman request: { "user":1, "name":"Max AP 05" } However the problem that I now have is that the initial UserIdexSerializer is rendered useless. This serializer determines the fields to show in a GET request but in consequence imposes the fields required in a POST request. What I'm trying to do is: POST a new AP object only using the user ID Show the UserIndexSerializer fields during a GET request (first_name, last_name, but not the ID) How can I make this work? I have found and read this post. I tried using different views, one for listing my models and one for creating a new one: from rest_framework import serializers from ..models.model_art_piece import AP from .serializers_user import * class APIndexSerializer(serializers.ModelSerializer): user = UserIndexSerializer() class Meta: model = AP fields = [ 'id', 'user', 'name' ] class APCreateSerializer(serializers.ModelSerializer): user = UserIDSerializer() class Meta: model = AP fields = [ 'id', 'user', 'name' ] def create(self, validated_data): ap = AP.objects.create(**validated_data) return ap class APDetailsSerializer(serializers.ModelSerializer): class Meta: model = AP … -

Wagtail large list within stream field block
We use wagtail for our blogs that are part of an eCommerce site. When we want to add a product to the blog as it stands we have to put the exact product name in which then matches on save. As names can change this then breaks that blog which isnt ideal. What we would like to do is add a field to our streamfield block that lets you pick from our list of products, however as we have 200k+ products and there might be up to 20 products on each blog loading the list into a dropdown is no good. What we need is to replicate what we do in Django admin using django-autocomplete-light where you start typing and get results based on that rather than loading the list into the HTML. What we cant work out is how to do that within a streamfield block, I have seen libraries like "Wagtail Autocomplete" however it seems you can only use that as a panel rather than within a block. As far as we can see you can only use sub-classes of wagtail.core.blocks or they dont show up in the interface. Any ideas? Thanks in advance! -
Overriding Django RelatedManager and Queryset to filter on a field in the Through Model
I have two models that are linked via Many-To-Many field via third Through Model. The Through Model has some extra fields in it. I want to override the RelatedManager to produce some custom QuerySets that use the extra fields in the Through Model. The caveat is that my Through Model is created using a subclass/mixin that defines the extra fields. What I want to be able to do is get all the Gene objects related to the SampleBatch that have an active status of 1 in the SampleBatchGene instances linking the Many-to-Many fields: In [1]: SampleBatch.objects.get(sample__lab_number="18_11998").genes.active() Out[1]: <QuerySet [<Gene: BAP1>]> This is what I have so far: class SampleBatch(models.Model): sample = models.ForeignKey(Sample, on_delete=models.CASCADE) batch = models.ForeignKey(Batch, on_delete=models.CASCADE) genes = models.ManyToManyField( "Gene", through='SampleBatchGene', related_name='samplebatches', blank=True, through_fields=('samplebatch', 'gene') ) class Meta: managed = True db_table = 'sample_batch' unique_together = (('sample', 'batch'),) verbose_name_plural = "Sample batches" def __str__(self): return '{}-{}'.format(self.sample, self.batch) class Gene(models.Model): gene_id = models.BigAutoField(primary_key=True) gene_name = models.CharField(unique=True, max_length=255, db_index=True) hgnc_number = models.IntegerField(unique=True, db_index=True) class Meta: managed = True db_table = 'gene' def __str__(self): return self.gene_name class ActiveQuerySet(models.QuerySet): def active(self): return self.filter(active=1) def inactive(self): return self.filter(active=0) class LinkMixin(models.Model): ACTIVE_CHOICES = ( (0, 'Inactive'), (1, 'Active') ) activated = models.DateTimeField(default=timezone.now) active = models.IntegerField( … -
django unable to show search result
I'm trying to do a search function on my home page. What it should does is that when the user clicked the on the Search button, the url should change from http://127.0.0.1:8000/ to http://127.0.0.1:8000/search.html and return the search result.

Python Sending email
I have this code for sending emails. An email is supposed to be sent to an Admin when a staff applies for leave and another one back to the staff as soon as the leave application is processed. I have the first part working ok. An admin user is indeed receiving the leave application email but once they processes it, the staff isnt receiving the feedback email. I suspect am getting it wrong how am grabbing the user email from the leave_obj but can figure out any other way. To the best of my knowledge user.email should work since there's a foreign key relationship between the leave, employee and user models. What am I missing? Below is all my relevant code. send_email function: def send_email( name: str, email: str, subject: str, message: str, obj: object = None, cc_list: list = None, template: str = "generic", template_path: str = "C:/Projects/hr_app/humanresource/src/templates/email", ): context = { "name": name, "subject": subject, "message": message, "object": obj, "SITE": Site.objects.get_current(), } email_subject = render_to_string( f"{template_path}/{template}_email_subject.txt", context ).replace("\n", "") email_txt_body = render_to_string( f"{template_path}/{template}_email_body.txt", context ) email_html_body = render_to_string( f"{template_path}/{template}_email_body.html", context ).replace("\n", "") subject = email_subject from_email = settings.DEFAULT_FROM_EMAIL to_email = f"{name} <{email}>" text_content = email_txt_body html_content = email_html_body … -
Django flatpages The empty path didn't match any of these
On the administration page, I set the URL for the Django flat pages to "/", which is expected to be displayed as the home page at http://127.0.0.1:8000/. Doing so I encountered an error: Request Method: GET Request URL: http://127.0.0.1:8000/ Using the URLconf defined in core.urls, Django tried these URL patterns, in this order: admin/ <path:url> The empty path didn't match any of these.

Celery/Kombu SimpleQueue.get() never returns even when message appears in queue. Why?
This has taken some time to nail this far and gets more mysterious with every step. I'm using a Kombu SimpleQueue quite effectively to send messages to a Celery task. I though all my problems solved to be honest as that's what I need and SimpleQueue delivers it elegantly. Until ... To put it into context, I have a Django site, and a Celery task all working beautifully together. I can put a message on the queue and read it as follows: from time import sleep from celery import current_app from celery.utils.log import get_logger from kombu.simple import SimpleQueue logger = get_logger(__name__) def q_name(task_id): return f'MySimpleQueueFor_{task_id}' def send_to_task(task_id, message): with Connection(current_app.conf.broker_write_url) as conn: q = conn.SimpleQueue(q_name(task_id)) q.put(message) print(f'Sent: {message} to {q_name(task_id)}') q.close() def check_for_message(q, task_id): try: message = q.get_nowait() # Raises an Empty exception if the Queue is empty payload = message.payload message.ack() # remove message from queue q.close() return payload except q.Empty: return None @app.task(bind=True) def my_task(self, *args, **kwargs): with Connection(current_app.conf.broker_read_url) as conn: task_id = self.request.id q = conn.SimpleQueue(q_name(task_id)) while True: message = check_for_message(q, task_id) logger.info(f'Received: {message} from {q.name}') sleep(0.1) With a task_id in hand I can send any message to the task I and I can see the messages … -
