</p>

Streamlit-pydantic makes it easy to auto-generate UI elements from [Pydantic](https://github.com/samuelcolvin/pydantic/) models or [dataclasses](https://docs.python.org/3/library/dataclasses.html). Just define your data model and turn it into a full-fledged UI form. It supports data validation, nested models, and field limitations. Streamlit-pydantic can be easily integrated into any Streamlit app.

## Highlights

- 🪄&nbsp; Auto-generated UI elements from Pydantic models & Dataclasses.
- 📇&nbsp; Out-of-the-box data validation.
- 📑&nbsp; Supports nested Pydantic models.
- 📏&nbsp; Supports field limits and customizations.
- 🎈&nbsp; Easy to integrate into any Streamlit app.

## Getting Started

### Installation

```bash
pip install streamlit-pydantic
```

### Usage

1. Create a script (`my_script.py`) with a Pydantic model and render it via `pydantic_form`:

    ```python
    import streamlit as st
    import streamlit_pydantic as sp
    from pydantic import BaseModel


    class ExampleModel(BaseModel):
        some_text: str
        some_number: int
        some_boolean: bool

    data = sp.pydantic_form(key="my_sample_form", model=ExampleModel)
    if data:
        st.json(data.model_dump())
    ```

2. Run the Streamlit server on the Python script: `streamlit run my_script.py`

3. You can find additional examples in the [examples](#examples) section below.

## Examples

     👉&nbsp; Try out and explore these examples in our playground <a href="https://st-pydantic.streamlit.app/">here</a>
</p>

The following collection of examples demonstrates how Streamlit Pydantic can be applied in more advanced scenarios. You can find additional - even more advanced - examples in the [examples folder](./examples) or on the [playground](https://st-pydantic.streamlit.app/).

### Simple Form

```python
import streamlit as st
import streamlit_pydantic as sp
from pydantic import BaseModel


class ExampleModel(BaseModel):
    some_text: str
    some_number: int
    some_boolean: bool

data = sp.pydantic_form(key="my_sample_form", model=ExampleModel)
if data:
    st.json(data.model_dump())
```

### Date Validation

```python
import streamlit as st
import streamlit_pydantic as sp
from pydantic import BaseModel, Field, HttpUrl
from pydantic_extra_types.color import Color

class ExampleModel(BaseModel):
    url: HttpUrl
    color: Color = Field("blue", format="text")
    email: str = Field(..., max_length=100, regex=r"^\S+@\S+$")

data = sp.pydantic_form(key="my_form", model=ExampleModel)
if data:
    st.json(data.model_dump_json())
```

### Dataclasses Support

```python
import dataclasses
import json

import streamlit as st
from pydantic.json import pydantic_encoder

import streamlit_pydantic as sp


@dataclasses.dataclass
class ExampleModel:
    some_number: int
    some_boolean: bool
    some_text: str = "default input"


data = sp.pydantic_form(key="my_dataclass_form", model=ExampleModel)
if data:
    st.json(dataclasses.asdict(data))
```

### Complex Nested Model

```python
from enum import Enum
from typing import Set

import streamlit as st
from pydantic import BaseModel, Field

import streamlit_pydantic as sp


class OtherData(BaseModel):
    text: str
    integer: int


class SelectionValue(str, Enum):
    FOO = "foo"
    BAR = "bar"


class ExampleModel(BaseModel):
    long_text: str = Field(
        ..., format="multi-line", description="Unlimited text property"
    )
    integer_in_range: int = Field(
        20,
        ge=10,
        le=30,
        multiple_of=2,
        description="Number property with a limited range.",
    )
    single_selection: SelectionValue = Field(
        ..., description="Only select a single item from a set."
    )
    multi_selection: Set[SelectionValue] = Field(
        ..., description="Allows multiple items from a set."
    )
    read_only_text: str = Field(
        "Lorem ipsum dolor sit amet",
        description="This is a ready only text.",
        readOnly=True,
    )
    single_object: OtherData = Field(
        ...,
        description="Another object embedded into this model.",
    )


data = sp.pydantic_form(key="my_form", model=ExampleModel)
if data:
    st.json(data.model_dump_json())
```

### Render Input

```python
from pydantic import BaseModel

import streamlit_pydantic as sp


class ExampleModel(BaseModel):
    some_text: str
    some_number: int = 10  # Optional
    some_boolean: bool = True  # Option


input_data = sp.pydantic_input(
    "model_input", model=ExampleModel, group_optional_fields="sidebar"
)
```

### Render Output

```python
import datetime

from pydantic import BaseModel, Field

import streamlit_pydantic as sp


class ExampleModel(BaseModel):
    text: str = Field(..., description="A text property")
    integer: int = Field(..., description="An integer property.")
    date: datetime.date = Field(..., description="A date.")


instance = ExampleModel(text="Some text", integer=40, date=datetime.date.today())
sp.pydantic_output(instance)
```

### Custom Form

```python
import streamlit as st
from pydantic import BaseModel

import streamlit_pydantic as sp


class ExampleModel(BaseModel):
    some_text: str
    some_number: int = 10
    some_boolean: bool = True


with st.form(key="pydantic_form"):
    data = sp.pydantic_input(key="my_custom_form_model", model=ExampleModel)
    submit_button = st.form_submit_button(label="Submit")
    obj = ExampleModel(data)

if data:
    st.json(obj.model_dump())
```

## Documentation

The API documentation can be found [here](./docs). To generate UI elements, you can use the high-level [`pydantic_form`](./docs/streamlit_pydantic.ui_renderer.md#function-pydantic_form) method. Or the more flexible lower-level [`pydantic_input`](./docs/streamlit_pydantic.ui_renderer.md#function-pydantic_input) and [`pydantic_output`](./docs/streamlit_pydantic.ui_renderer.md#function-pydantic_output) methods. See the [examples](#examples) section on how to use those methods.

This repo uses [Rye](https://rye.astral.sh/) for development. To get started, [install Rye](https://rye.astral.sh/) and sync the project:

```bash
rye sync
```

Run the playground app:

```bash
rye run playground
```

Run linting and type checks:

```bash
rye run checks
```

> [!TIP]
> The linting and formatting is using [ruff](https://github.com/astral-sh/ruff) and
> type-checking is done with [mypy](https://github.com/python/mypy). You can use
> the ruff and mypy extensions of your IDE to automatically run these checks
> during development.

Format the code:

```bash
rye run format
```

Run tests:

```bash
rye test
```
