# Django Search Input Field

The Django Search Input Field package simplifies the process of integrating Ajax searchable input fields into Django forms. This package provides flexibility for searching model fields or any custom data, enhancing the user experience and improving search functionality within your Django applications.

## Installation

You can install the package via pip:

```shell
pip install django-search-input-field
```

Once installed, add the app to your `INSTALLED_APPS` in your Django settings:

```python
INSTALLED_APPS = [
    ...
    "django_search_input_field"
]
```

Finally, include the package's URLs in your project's URL configuration:

```python
urlpatterns = [
    path('django_search_input_field/', include('django_search_input_field.urls')),
]
```

## Usage

### Field Types

#### SelectSearchCharField

The `SelectSearchCharField` is used to perform a search on a specified field and return the field value.

Example Usage:

```python
from django import forms
from django_search_input_field.field import SelectSearchCharField
from Main.models import Customers

class CustomerSearchFieldForm(forms.Form):
    name = SelectSearchCharField(field="name", model=Customers)
```
#### 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:
```python 
from django import forms
from django_search_input_field.field import SearchModelField
from Main.models import Customers

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

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

Example Usage:
```python
from django import forms
from django_search_input_field.field import CharRelatedField, SearchModelField
from Main.models import Customers

class CustomerSearchFieldWithRelatedForm(forms.Form):
    name = SearchModelField(model=Customers, search_field="name")
    email = CharRelatedField(related_field="name", related_search_input="email")
```

### 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:


```python
from django_search_input_field.providers import SearchModelProvider

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

    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:

```python
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=[YourCustomPermission],
        query_function_name=CustomModelProvider.query_function_name,
        min_search_length=1,
    )
```
