#models.py
from markdownx.models import MarkdownxField
class MyModel(models.Model):
myfield = MarkdownxField()...and then, include a form's required media in the template using {{ form.media }}:
<form method="POST" action="">{% csrf_token %}
{{ form }}
</form>
{{ form.media }}#forms.py
from markdownx.fields import MarkdownxFormField
class MyForm(forms.Form):
myfield = MarkdownxFormField()...and then, include a form's required media in the template using {{ form.media }}:
<form method="POST" action="">{% csrf_token %}
{{ form }}
</form>
{{ form.media }}When using included MarkdowxModel class in your models, just use MarkdownxModelAdmin as follows:
#admin.py
from django.contrib import admin
from markdownx.admin import MarkdownxModelAdmin
from .models import MyModel
admin.site.register(MyModel, MarkdownxModelAdmin)However, when you want to use markdownx with other classes – lets say TextField – than override default widget as follows:
#admin.py
from django.db import models
from django.contrib import admin
from markdownx.widgets import AdminMarkdownxWidget
from .models import MyModel
class MyModelAdmin(admin.ModelAdmin):
formfield_overrides = {
models.TextField: {'widget': AdminMarkdownxWidget},
}
admin.site.register(MyModel, MyModelAdmin)Place settings in your settings.py to override default values:
#settings.py
# Markdownify
MARKDOWNX_MARKDOWNIFY_FUNCTION = 'markdownx.utils.markdownify' # Default function that compiles markdown using defined extensions. Using custom function can allow you to pre-process or post-process markdown text. See below for more info.
# Markdown extensions
MARKDOWNX_MARKDOWN_EXTENSIONS = [] # List of used markdown extensions. See below for more info.
MARKDOWNX_MARKDOWN_EXTENSION_CONFIGS = {} # Configuration object for used markdown extensions
# Markdown urls
MARKDOWNX_URLS_PATH = '/markdownx/markdownify/' # URL that returns compiled markdown text.
MARKDOWNX_UPLOAD_URLS_PATH = '/markdownx/upload/' # URL that accepts file uploads, returns markdown notation of the image.
# Media path
MARKDOWNX_MEDIA_PATH = 'markdownx/' # Path, where images will be stored in MEDIA_ROOT folder
# Image
MARKDOWNX_UPLOAD_MAX_SIZE = 52428800 # 50MB - maximum file size
MARKDOWNX_UPLOAD_CONTENT_TYPES = ['image/jpeg', 'image/png'] # Acceptable file content types
MARKDOWNX_IMAGE_MAX_SIZE = {'size': (500, 500), 'quality': 90,} # Different options describing final image processing: size, compression etc. See below for more info.
# Editor
MARKDOWNX_EDITOR_RESIZABLE = True # Update editor's height to inner content height while typingDefault function that compiles markdown looks like:
# utils.py
import markdown
from .settings import MARKDOWNX_MARKDOWN_EXTENSIONS, MARKDOWNX_MARKDOWN_EXTENSION_CONFIGS
def markdownify(content):
return markdown.markdown(content, extensions=MARKDOWNX_MARKDOWN_EXTENSIONS, extension_configs=MARKDOWNX_MARKDOWN_EXTENSION_CONFIGS)#settings.py
MARKDOWNX_MARKDOWN_EXTENSIONS = [
'markdown.extensions.extra',
'markdown.extensions.nl2br',
'markdown.extensions.smarty',
]Visit https://pythonhosted.org/Markdown/extensions/index.html to read more about markdown extensions.
Dict properties:
- size – (width, height). When
0used, i.e.: (500,0), property will figure out proper height by itself - quality – default:
90– image quality, from0(full compression) to100(no compression) - crop – default:
False– ifTrue, usesizeto crop final image - upscale – default:
False– if image dimensions are smaller than those insize, upscale image tosizedimensions
Default widget's template looks like:
<div class="markdownx">
{{ markdownx_editor }}
<div class="markdownx-preview"></div>
</div>When you want to use Bootstrap 3 and side-by-side panes (as in preview image above), just place markdownx/widget.html file in your project's 'TEMPLATE_DIRS' folder with:
<div class="markdownx row">
<div class="col-md-6">
{{ markdownx_editor }}
</div>
<div class="col-md-6">
<div class="markdownx-preview"></div>
</div>
</div>Markdown uses ![]() syntax to insert uploaded image file. This generates very simple html <image> tag. When you want to have more control and use your own html tags just create custom form_valid() function in ImageUploadView class.
Default ImageUploadView class looks like:
#views.py
from django.http import JsonResponse
from django.views.generic.edit import FormView
from .forms import ImageForm
class ImageUploadView(FormView):
template_name = "dummy.html"
form_class = ImageForm
success_url = '/'
def form_invalid(self, form):
response = super(ImageUploadView, self).form_invalid(form)
if self.request.is_ajax():
return JsonResponse(form.errors, status=400)
else:
return response
def form_valid(self, form):
image_path = form.save()
response = super(ImageUploadView, self).form_valid(form)
if self.request.is_ajax():
image_code = ''.format(image_path)
return JsonResponse({'image_code': image_code})
else:
return responseEach markdownx jQuery object triggers two basic events:
- 'markdownx.init'
- 'markdownx.update' – also returns 'response' variable containing markdownified text
$('.markdownx').on('markdownx.init', function() {
console.log("INIT");
});
$('.markdownx').on('markdownx.update', function(e, response) {
console.log("UPDATE" + response);
});- Markdown

It would be nice if anyone could support this project by adding missing functionality:
- tests
- JS intelligent auto-scrolling when side-by-side panes used
django-markdownx was inspired by great django-images and django-bootstrap-markdown packages.
