When I was working with Django the other day I had a model which contained 3 textareas. I only wanted 2 of the 3 to use TinyMCE for mark-up in the Admin. I worked out how to achieve this and here’s a quick guide.

1. Install TinyMCE as explained in an earlier post.
2. Make sure the tiny_mce folder (the one you download from tinymce.moxiecode.com/) is also in you site media js folder (/[sitemedia]/js/tiny_mce/) or change the TINYMCE_JS_URL to the correct folder in your settings.py.
3. In your settings.py define what you want the default tinymce to look like, for example:
   TINYMCE_DEFAULT_CONFIG = {
'plugins' : "safari,spellchecker,save,advlink,iespell,paste,xhtmlxtras,",
'theme': 'advanced',
'theme_advanced_buttons1': "bold, italic, underline, strikethrough,|,justifyleft,justifycenter,justifyright,justifyfull,|,bullist,numlist,|,outdent,indent,blockquote,",
'theme_advanced_buttons2':"undo,redo,|,link,unlink,anchor,cleanup,help,code,spellchecker",
'theme_advanced_buttons3':"",
'theme_advanced_buttons4':"",
'theme_advanced_toolbar_location' : "top",
'theme_advanced_toolbar_align' : "left",
'theme_advanced_statusbar_location' : "bottom",
'theme_advanced_resizing' : 'true',
}

4. In your model admin file add
   from tinymce.widgets import TinyMCE
5. And to the model’s admin class add:
   def formfield_for_dbfield(self, db_field, **kwargs):
if db_field.name == '[your_field_name]': # you can add more fields here by using 'or'
kwargs['widget'] = TinyMCE(attrs={'cols':80, 'rows': 30})
try:
del kwargs['request']
except KeyError:
pass
return db_field.formfield(**kwargs)
return super([model_admin_class_name],self).formfield_for_dbfield(db_field, **kwargs)
