# django-markdownfield [](https://pypi.org/project/django-markdownfield/)
A simple custom field for Django that can safely render Markdown and store it in the database.
Your text is stored in a `MarkdownField`. When the model is saved, django-markdownfield will
parse the Markdown, render it, sanitise it with [bleach](https://github.com/mozilla/bleach), and store
the result in a `RenderedMarkdownField` for display to end users.
django-markdownfield also implements the [EasyMDE](https://github.com/nodecraft/easy-markdown-editor)
editor in admin views to make working with Markdown easier.
## Implementation
Implementing django-markdownfield is simple. See the below example.
```python
from django.db import models
from markdownfield.models import MarkdownField, RenderedMarkdownField
from markdownfield.validators import VALIDATOR_STANDARD
class Page(models.Model):
text = MarkdownField(rendered_field='text_rendered', validator=VALIDATOR_STANDARD)
text_rendered = RenderedMarkdownField()
```
Please also set `SITE_URL` in your Django configuration - it will be needed for detecting
external links.
```python
SITE_URL = "https://example.com"
```
To disable the EasyMDE editor, see the amended line below.
```python
text = MarkdownField(rendered_field='text_rendered', use_editor=False, use_admin_editor=True)
```
### Use in templates
To use the rendered markdown in templates, just use the `RenderedMarkdownField()` you created on
your model, like below. This field should be marked as safe with the `safe` filter to ensure it
displays correctly.
```djangotemplate
{{ post.text_rendered | safe }}
```
## Validators
django-markdownfield comes with a number of validators, which are used to process and clean
the output of the markdown engine
### VALIDATOR_STANDARD
```python
from markdownfield.validators import VALIDATOR_STANDARD
```
This validator strips any tags that are not used by standard Markdown. It also automatically links
any URLs in the output, adding `class="external"`, `rel="nofollow noopener noreferrer"`, and
`target="_blank"` to any URLs which it determines to be external.
### VALIDATOR_CLASSY
```python
from markdownfield.validators import VALIDATOR_CLASSY
```
This validator does much the same as `VALIDATOR_STANDARD`, but it allows you to set the class on
links and images. This is useful to create buttons and other enhanced links.
### VALIDATOR_NULL
```python
from markdownfield.validators import VALIDATOR_NULL
```
This validator does not call [bleach](https://github.com/mozilla/bleach) to sanitize the output at all.
This is **not safe for user input**. It allows arbitrary (unsafe) HTML in your markdown input.
### Creating Custom Validators
To create a custom validator, just create an instance of the `markdownfield.validators.Validator`
dataclass. An example of this is shown below.
```python
from markdownfield.validators import Validator
# allows only bold and italic text
VALIDATOR_COMMENTS = Validator(
allowed_tags=["b", "i", "strong", "em"],
allowed_attrs={},
linkify=False
)
```
You can also find a standard set of markdown-safe tags and attrs in `markdownfield.validators`, and extend
that.
```python
from markdownfield.validators import Validator, MARKDOWN_TAGS, MARKDOWN_ATTRS
# allows all standard markdown features,
# but also allows the class to be set on images and links
VALIDATOR_CLASSY = Validator(
allowed_tags=MARKDOWN_TAGS,
allowed_attrs={
**MARKDOWN_ATTRS,
'img': ['src', 'alt', 'title', 'class'],
'a': ['href', 'alt', 'title', 'name', 'class']
}
)
```
