Usage

Model

from django.db import models
from martor.models import MartorField

class Post(models.Model):
    description = MartorField()

Form

from django import forms
from martor.fields import MartorFormField

class PostForm(forms.Form):
    description = MartorFormField()

Admin

from django.db import models
from django.contrib import admin

from martor.widgets import AdminMartorWidget

from yourapp.models import YourModel

class YourModelAdmin(admin.ModelAdmin):
    formfield_overrides = {
        models.TextField: {'widget': AdminMartorWidget},
    }

admin.site.register(YourModel, YourModelAdmin)

Template Renderer

Simply safely parse markdown content as html output by loading templatetags from martor/templatetags/martortags.py.

{% load martortags %}
{{ field_name|safe_markdown }}

# example
{{ post.description|safe_markdown }}

Don't miss to include the required css & js files before use. You can take a look at this folder martor_demo/app/templates for more details. The below example is a one of the way to implement it when you choose the MARTOR_THEME = 'bootstrap':

{% extends "bootstrap/base.html" %}
{% load static %}
{% load martortags %}

{% block css %}
  <link href="{% static 'plugins/css/ace.min.css' %}" type="text/css" media="all" rel="stylesheet" />
  <link href="{% static 'martor/css/martor.bootstrap.min.css' %}" type="text/css" media="all" rel="stylesheet" />
{% endblock %}

{% block content %}
  <div class="martor-preview">
    <h1>Title: {{ post.title }}</h1>
    <p><b>Description:</b></p>
    <hr />
    {{ post.description|safe_markdown }}
  </div>
{% endblock %}

{% block js %}
  <script type="text/javascript" src="{% static 'plugins/js/highlight.min.js' %}"></script>
  <script>
    $('.martor-preview pre').each(function(i, block){
        hljs.highlightBlock(block);
    });
  </script>
{% endblock %}

Template Editor Form

Different with Template Renderer, the Template Editor Form have more css & javascript dependencies.

{% extends "bootstrap/base.html" %}
{% load static %}

{% block css %}
  <link href="{% static 'plugins/css/ace.min.css' %}" type="text/css" media="all" rel="stylesheet" />
  <link href="{% static 'plugins/css/resizable.min.css' %}" type="text/css" media="all" rel="stylesheet" />
  <link href="{% static 'martor/css/martor.bootstrap.min.css' %}" type="text/css" media="all" rel="stylesheet" />
{% endblock %}

{% block content %}
  <form class="form" method="post">{% csrf_token %}
    <div class="form-group">
      {{ form.title }}
    </div>
    <div class="form-group">
      {{ form.description }}
    </div>
    <div class="form-group">
      <button class="btn btn-success">
        <i class="save icon"></i> Save Post
      </button>
    </div>
  </form>
{% endblock %}

{% block js %}
  <script type="text/javascript" src="{% static 'plugins/js/ace.js' %}"></script>
  <script type="text/javascript" src="{% static 'plugins/js/mode-markdown.js' %}"></script>
  <script type="text/javascript" src="{% static 'plugins/js/ext-language_tools.js' %}"></script>
  <script type="text/javascript" src="{% static 'plugins/js/theme-github.js' %}"></script>
  <script type="text/javascript" src="{% static 'plugins/js/typo.js' %}"></script>
  <script type="text/javascript" src="{% static 'plugins/js/spellcheck.js' %}"></script>
  <script type="text/javascript" src="{% static 'plugins/js/highlight.min.js' %}"></script>
  <script type="text/javascript" src="{% static 'plugins/js/resizable.min.js' %}"></script>
  <script type="text/javascript" src="{% static 'plugins/js/emojis.min.js' %}"></script>
  <script type="text/javascript" src="{% static 'martor/js/martor.bootstrap.min.js' %}"></script>
{% endblock %}
