Django Framework Not Picking Up Custom CSS
I am using Django Framework for my blog, however when I am trying to style my webpage, the classes are not being picked up. These are the images of my div with latest-articles class: As you can see from the next image, the HTML recognises the class as display: block; However, my CSS clearly states that it is of display: block; This is my CSS code: .latest-articles { /* dont think this class is being picked up */ display: flex; flex-wrap: wrap; flex-direction: row; justify-content: center; align-items: center; padding-top: 0; text-align: center; position: relative; padding: 10px; } Other CSS changes I have made previously have worked so I am unsure as to why this does not work. Any additional information can be provided, and any help is greatly appreciated. -

Adding help text to a django from
I want to add help text/tool tip when a user hovers over a form field. I have a model form based on this model: class MyModel(TimeStampedModel): MY_CHOICES = [tuple([x,x]) for x in range(1,8)] p1 = models.IntegerField("P1”, default='1', help_text=‘text1’) p2 = models.IntegerField(“P2”, default=‘1’, , help_text=‘text2’) Parent = models.ForeignKey(ParentModel, on_delete=models.CASCADE) The form itself looks like: class MyModelForm(ModelForm): def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.helper = FormHelper(self) self.helper.form_id = 'id-CaseForm' self.helper.form_class = 'blueForms' self.helper.form_method = 'post' self.helper.form_tag = False self.helper.help_text_inline = False self.helper.form_show_labels = False self.helper.layout = Layout( Row(Field(PrependedText('p1', ‘field_label1’, wrapper_class='col-12 col-lg-6 pe-0 stretchprepend'))), Row(Field(PrependedText('p2’, ‘field_label2’, wrapper_class='col-12 col-lg-6 pe-0 stretchprepend’)))) CHOICES = [tuple([x,x]) for x in range(1,8)] p1 = IntegerField( label='field_label1', widget=Select(choices=CHOICES)) p2 = IntegerField( label='field_label2’, widget=Select(choices=CHOICES)) class Meta: model = MyModel fields = ['p1', 'p2’,] And this is displayed as a crispy form in the template: {% crispy MyModelForm %} I want the user to see some help text when they hover over the fields. This help text could be the help_text from the model, or I am happy to put it somewhere else (although it should go in either the model or the form, not in the template). Any help appreciated. -
How should queryset be set for related fields
I have two models named book and chapter. each book can have many chapters, so models are like: class Book(models.Model): title = models.CharField(max_length=100) class Chapter(models.Model): title = models.CharField(max_length=100) book = models.ForeignKey("books.Book", on_delete=models.CASCADE) and serializers are like: class BookSerializer(serializers.ModelSerializer): class Meta: model = Book fields = ["title"] class ChapterSerializer(serializers.ModelSerializer): book = serializers.PrimaryKeyRelatedField(queryset=Book.objects.all()) class Meta: model = Chapter fields = ["title", "chapter_number", "text", "book"] So my question is here: Is it OK to set queryset=Book.objects.all()) for related field? I mean, if the number of books gets bigger, wouldn't be any problem to query all the books to set the right book? -

Doing data validation after saving the object in a atomic transaction. Django and PostgreSQL
The current flow I use is this: # Here there is long and complicated verification to check that the submitted data is valid, # involving lots of calculations and queries. with transaction.atomic(): # save the submitted data But instead I could do def saved_data_is_valid(): # some short and simple calculations. ... # skip the validation before saving data. with transaction.atomic(): # save the submitted data in the database without commiting it. if not saved_data_is_valid(): raise Exception("Some exception so the transaction will roll back") I wonder what the performance hit for the database will be with all the dead rows this will create, considering that AUTOVACUUM is ON, and default_transaction_isolation is read committed. Also considering that the submitted data is in most cases valid. -

How to create django media sub path with filebrowser
When uploading a media file through filebrowser in django-tinymce, I want to create a new folder under the upload folder based on the uploaded date (like ckeditor). For example, if you upload the abc.png file on December 3, 2022, I want to keep the path of [/{django-project}/media/upload/2022/12/3/abc.png], not [/{django-project}/media/abc.png]. I know that the file name can be edited by using the signals of the filebrowser, but I don't know how to change the file path. For example, if you upload the abc.png file on December 3, 2022, I want to keep the path of [/{django-project}/media/upload/2022/12/3/abc.png], not [/{django-project}/media/abc.png].
