Django filters startswith
filters by creating a very simple site. There is a view and the user searches an object that I added as an admin. Views.py from django.shortcuts import render from .filters import * def home(request): myqs = Kati.objects.all() myFilter = SearchForm(request.GET, queryset=myqs) return render(request, 'home.html', {'myFilter':myFilter}) Models.py class Kati(models.Model): name = models.CharField(max_length=200) product = models.CharField(max_length=200) timi = models.CharField(max_length=200) Filters.py import django_filters class SearchForm(django_filters.FilterSet): class Meta: model = Kati fields = ['name','product','timi'] Html <form action='' method='get'> {{myFilter.form}} <button>OK</button> </form> {%for i in myFilter.qs%} <p>{{i.name}}</p> <p>{{i.product}}</p> <p>{{i.timi}}</p> {%endfor%} It works but is there a way to show an object just by typing the first letter. For example if the name is abcd show the object if you write ab. Like __startswith__. -

Using signals in django while extending user model
Basically I have 2 models that are 1 to 1 related with User model, First model in Employee and second one is Customer. I am also using signals for updates #Signal functions inside each model @receiver(post_save, sender=User) def create_customer(sender, instance, created, **kwargs): if created: Customer.objects.create(user=instance) @receiver(post_save, sender=User) def update_customer(sender, instance, created, **kwargs): if created == False: instance.customer.save() When I register a user it gets duplicated both in customer and employee. Is there a way to prevent this? -
Customize group permissions in django?
I need to make role-based authentication. Firstly, I made group permissions for all my apps. I assigned some of them to role according to role's ability. from django.contrib.auth.models import AbstractUser from django.contrib.auth.models import Group class Role(models.Model): title = models.CharField(max_length=32) groups = models.ManyToManyField(Group) def __str__(self) -> str: return self.title Here you can a see driver role which has access on some group permissions (in fact they are just names of groups) Now I have a user model: class Users(AbstractUser): role = models.ForeignKey( Role, on_delete=models.CASCADE, related_name='roles', blank=True, null=True) def __str__(self): return (self.username) I don't want to pick group permissions every time when I created a new staff user. I just want to set a role to a user and it should automatically pick all permissions based on selected role's groups. How to customize groups in django models? -
Post a CharField to an ArrayField in from React to Django using Axios
I am trying to create a feature where if a user writes a post the ID of the post goes into an ArrayField in the User model so a list of their writing can be accessed. I introduced a new column in the User database, made the necessary migrations and trialed this feature just saving one post ID which worked fine. The issue arose when I made the model field an ArrayField. Now when I do the POST request I get an error response : "{\"posts_written\":{\"0\":[\"Expected a list of items but got type \\\"str\\\".\"]} Currently I am writing the REQUEST as let newPost = new FormData() newPost.append('title', title) newPost.append('content', content) updatePostList.append('posts_written', id + ',') await API.patch(`/profile/user/${loggedInProfile.id}/update/`, updateArticleList, { headers: { 'Authorization': `Token ${sessionToken}`, 'Content-Type': 'multipart/form-data', }, }) I am unsure of how to write the POST request to work with the ArrayField, I have looked online for answers but can't find anything. Here is the User model class User(AbstractUser): id = models.CharField(max_length=36, default=generate_unique_id, primary_key=True) username = models.CharField(max_length=250, unique=True) profile_image = models.ImageField(upload_to='profile_images', default='/profile_images/DefaultAvatar.png') bio = models.CharField(max_length=500, default='', blank=True, null=True) display_name = models.CharField(max_length=250, blank=True, null=True) articles_written = ArrayField( ArrayField(models.CharField(max_length=36, blank=True, null=True)), ) Thank you -

Django crispy forms prepend box set width
I am using crispy forms to make a django form which has several rows. The default behaviour is for the prepend box to be just the size of the text within it. However this looks messy when there are several fields and I would prefer the prepend box to be an equal width for all. An ugly hack is to just pad the prepend boxes that contain shorter strings with spaces but this is obviously not ideal. Any advoice on how to adjust the width of the prepend box to make them equal across fields? This if the form helper I have where I define the prepend text self.helper.layout = Layout( Row(Field(PrependedText('field1', 'Field1prependtext &nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp&nbsp', wrapper_class='col-md-4 pe-0'))), Row(Field(PrependedText('field1', 'Field1prependtextlonger ', wrapper_class='col-md-4 pe-0'))),) -

overredieg jinja2 for customized view on django templates
hi I wanna overriding html.py in venv/Lib/coreschema/encodings/html.py. this is a method to need overriding: def determine_html_template(schema): if isinstance(schema, Array): if schema.unique_items and isinstance(schema.items, Enum): # Actually only for *unordered* input return '/bootstrap3/inputs/select_multiple.html' # TODO: Comma seperated inputs return 'bootstrap3/inputs/textarea.html' elif isinstance(schema, Object): # TODO: Fieldsets return 'bootstrap3/inputs/textarea.html' elif isinstance(schema, Number): return 'bootstrap3/inputs/input.html' elif isinstance(schema, Boolean): # TODO: nullable boolean return 'bootstrap3/inputs/checkbox.html' elif isinstance(schema, Enum): # TODO: display values return 'bootstrap3/inputs/select.html' # String: if schema.format == 'textarea': return 'bootstrap3/inputs/textarea.html' return 'bootstrap3/inputs/input.html' and this lines : if isinstance(schema, Array): if schema.unique_items and isinstance(schema.items, Enum): # Actually only for *unordered* input return '/bootstrap3/inputs/select_multiple.html' I want to modify select_multiple.html to custom_select_multiple.html in templates folder in my project directory. also this solution need to overriding some files and I do that. now its cant understand my custom file because in this method: env = jinja2.Environment(loader=jinja2.PackageLoader('coreschema', 'templates')) def render_to_form(schema): template = env.get_template('form.html') return template.render({ 'parent': schema, 'determine_html_template': determine_html_template, 'get_textarea_value': get_textarea_value, 'get_attrs': get_attrs }) used PackageLoader and jinja2 cant understand where is my file. and now how can I resolve this problem. actually I trying to resolve this with set custom urls but this not working. actually I dont know what I do. -
