from Main.models import Customers
from rest_framework.permissions import AllowAny

class CustomerSearchFieldForm(forms.Form):
    name = SelectSearchCharField(field="name", model=Customers, permissions=AllowAny)

SearchModelField

The SearchModelField is used to search based on a specified field but returns the entire model object, using the field for searching.

Example Usage:

from django import forms
from django_search_input_field.field import SearchModelField
from Main.models import Customers
from rest_framework.permissions import AllowAny

class CustomerSearchFieldForm(forms.Form):
    name = SearchModelField(model=Customers, search_field="name", permissions=AllowAny)

Related Form and CharRelatedField

The related form is used to fill related fields automatically when a SearchModelField is selected.

Example Usage:

from django_search_input_field.field import CharRelatedField, SearchModelField
from django_search_input_field.form import RelatedFillForm

from Main.models import Customers
from rest_framework.permissions import AllowAny

class CustomerSearchFieldWithRelatedForm(RelatedFillForm):
    name = SearchModelField(model=Customers, search_field="name", permissions=AllowAny)
    email = CharRelatedField(related_field="name", related_search_input="email")

Advanced Usage

The package provides the flexibility to customize the search behavior by creating custom providers. you can provide the provider name to the field using query_function_name parameter.

Custom Providers

You can create custom providers to tailor the search behavior according to your specific requirements.

Here's an example of creating a custom provider:

from django_search_input_field.providers import SearchModelProvider

class CustomModelProvider(SearchModelProvider):
    model = YourModel
    query_function_name = 'custom_search_function'
    auto_register = False

    def get_queryset(self):
        # Implement your custom queryset logic here
        return YourModel.objects.all()

    def get_filtered_queryset(self, function_filters, search_key):
        # Implement your custom filtered queryset logic here
        return YourModel.objects.filter(**function_filters)

    def get_filtered_options(self, function_filters, search_key):
        options = self.get_filtered_queryset(function_filters, search_key)
        return [ModelOption(option, serializer=None, object_str=lambda obj: str(obj)) for option in options]

Using Custom Providers

After creating a custom provider, you can use it in your form or field:

from django import forms
from django_search_input_field.field import SearchModelField
from .providers import CustomModelProvider

class YourForm(forms.Form):
    custom_field = SearchModelField(
        model=None,
        search_field="your_field",
        permissions=YourCustomPermissionsClass,
        query_function_name=CustomModelProvider.query_function_name,
        min_search_length=1,
    )
