Hey Ross, my guess is that either TinyMCE (or whatever richtext editor you are using) or Bleach is doing this.
Take a look at https://bitbucket.org/stephenmcd/mezzanine/src/85053c4590cd57c218718f9a99ee7f1ab2100319/mezzanine/core/defaults.py?at=default#cl-253 If Bleach is the culprit then adding canvas to that setting should fix it. Putting something like: register_setting( name="RICHTEXT_ALLOWED_TAGS", description=_("List of HTML tags that won't be stripped from " "``RichTextField`` instances."), editable=False, append=True, default=("canvas",), ) In your own default.py file will add canvas to the allowed list. If TinyMCE is the culprit I'm not sure how to fix it but you may be able to fix it by customizing the tinymce setup file, https://bitbucket.org/stephenmcd/mezzanine/src/85053c4590cd57c218718f9a99ee7f1ab2100319/mezzanine/core/static/mezzanine/js/tinymce_setup.js?at=default On Fri, Oct 31, 2014 at 12:00 PM, Ross Laird <[email protected]> wrote: > Turns out that the tag is not being stripped out but the display of the > tag inside the editor is being changed. > When I add <canvas> ... </canvas> within the editor, then save, then > re-open the HTML editing window, the canvas tag is changed to <p> ... </p>. > I see the p tag, and no canvas tag, in the editor. > But when I add the canvas tag inside the editor, save it, then look at the > source code of the resulting page (on the site), the canvas tag is indeed > there (and there is no p tag at that location). > So, the canvas tag is being accepted properly; but it is being shown as a > p tag inside the text editor. > > On Thursday, 30 October 2014 20:10:14 UTC-7, MattQ wrote: >> >> Add this line to your view: >> print( page.portfolioitem.content) >> And see the results in the console.
