using widgets to change the CSS of label in Django forms
I am trying to apply CSS styling to the admin login form in Django (version 3.1.3). I am able to customise the inputs easily enough using Widgets via the 'forms.TextInput(attrs={'class':'textinputclass'}) method however there seems to be no way to add CSS class to the labels? I can set the label to "false" so that it doesnt show up at all, but ideally I would like to be able to associate a CSS class to it. My code below shows the widgets being used for the text input for username and password. How do I do something similar for the label? ''' class MyAuthForm(AuthenticationForm): class Meta: model = Lesson fields = ['username', 'password'] def __init__(self, *args, **kwargs): super(MyAuthForm, self).__init__(*args, **kwargs) self.fields['username'].widget = forms.TextInput(attrs={'class': 'input', 'placeholder': 'Username'}) self.fields['username'].label = False self.fields['password'].widget = forms.PasswordInput(attrs={'class': 'input', 'placeholder': 'Password'}) self.fields['password'].label = False ''' -
How to populate model's new fields from OneToOneField in Django?

Django - StringRelatedField() not applied to query results when .values() provided
In my Django app, I'm finding that a StringRelatedField() on a serializer class isn't being applied when that serializer is used on a filter query where a set of field values have been specified - though it does work if the query returns all fields. Whew, that's a mouthful, let me break it down - I have two models, Report and User; each Report is associated with a User. Ideally, I want to query reports via get_queryset and in each report record, the value of the associated user should be the result of StringRelatedField(), the return value of the __str__ method on the User model (which is the user's first and last names). If my query returns all fields, this works perfectly... so the query Report.objects.filter(location__within=some_other_model.region) does the trick. However, I've found that querying only for the values that I actually need vastly improves performance, so my preference is to query like so: Report.objects.filter(location__within=some_other_model.region).values('id', 'location', 'user',) but the results of that query have the UUID foreign key of the record from the User table, they do not seem to have been replaced with the StringRelatedField(). Below, I have the view and serializer for Report, as well as the User model. … -

How can I speed up batch creating of multiple related objects?
I use this for simplicity. Let say I have 2 models here A and B. I want to use A.objects.bulk_create(a_list) and B.objects.bulk_create(b_list) to batch create both A and B objects. But, B reply on A. So, I have to batch creating those objects in a for loop like this: for _ in some_list: a = A.objects.create(**kwargs) B.objects.create(a=a, **kwargs) The problem is that the speed is too slow and I wannt speed up. So, is there a workaround to speed up this? -

Trying to create my first Django webpage but nothing loads when I run manage.py

Django: Adding multiple inline instances to a form

Django - How to automatically create a .docx file and save it to a model's FileField?
Here's my use case. I have a rental contract template (.docx file). I want to populate the fields of this contract by pulling data from my models and injecting them into the template (using Jinja tags), then save the output file directly to the database. So far so good. My problem is that I currently do this as a two step process; 1) open template, populate and save as new file; 2) upload the file as a FileField to my Model, thereby creating a duplicate... Is there a way for me to create and store the formatted file without first having to save it? (thus avoiding duplicates) According to this thread, the suggested approach is to use django.core.files.base.ContentFile and pass the content of the file as a string, like so. self.lease_draft.save("Name of the file", ContentFile("A string with the file content")) My problem is that ContentFile() only accepts strings or bytes as parameters. My input is a populated .docx file (DocxTemplate object), not a string. Any suggestions on how to approach this? Models.py class Booking(models.Model): lease_draft = models.FileField(upload_to='lease_drafts/', null=True) Views.py from django.core.files import File def populate_docx(self, template_path, context): draft_lease = DocxTemplate(template_path) /// Gets the template draft_lease.render(context) /// Populates the template self.lease_draft.save('Lease … -
Can you add a Browsable API into an ASP.NET application?
The Django web framework has a Browsable API and I would like to implement something similar in my ASP.NET (with ReactJS) application. Essentially, suppose that there's an API endpoint called api/test; I would like to be able to navigate to https://.../api/test in a web browser and be presented with a web page (React component) that contains what api/test normally returns but in a better, human-readable format like Django does. But when accessed as an API, it returns the content without the surrounding HTML page. The simple controller would look like: [ApiController] [Route("api/[controller]")] public class TestController : ControllerBase { [HttpGet] [Produces("text/json")] public IList<string> Get() { return new string[] { "hello", "world" }; } } It seems that something similar to Content Negotiation would work. So, I would either have to implement a custom formatter (which I'm not sure is the right approach) or make a middleware of my own. Does this sort of thing already exist somehow? Any suggestions on how to implement it if it doesn't already exist? Thanks in advance! -
