Django - Managing page content in Django Admin
Honestly, the scope of what you're looking for is too huge to cover in this format. There's a number of ways this could be done, but they're all going to require some work and customization based on the client's needs.
Flatpages could work if you allow HTML content and make sure the content is rendered as "safe" in the template. This really only covers the "content" area of the site, though. It wouldn't be wise to use flatpages for an entire site template, including header, sidebar, footer, etc.
You could create editable areas. So, you actually create models for things like headers, sidebars, footers, and modules within those areas, and then just pull them into the template as needed. Then, the client is only editing pieces of the template instead of responsible for the whole HTML document.
Forms are going to be a challenge, because they require backend-processing that requires a connected view. The client won't be able to just arbitrarily drop in some form code and have a form. But, you could use a third-party service form forms and just embed them in the available content regions. Or, there's a couple of django apps that try to implement a type of "form builder" in the admin. That might somehow let the client add a form via something like the shortcodes used in Wordpress, but you'd likely have to lay down some infrastructure to make that work.
At a certain point, stuff like this reaches a point of diminishing returns, though. The only way to allow total customization of the template is to drop down into the actual physical file and make changes there. You can make certain things easier for the client, but ultimately, they either need to scale back their customization needs or deal with the fact that they'll have to work with the filesystem.
I'm new to working with Django and am developing for a client who wants to be able to change page content in the Django Admin. They need to be able to change the html of the index page without editing the files on the server.
I know about flatfiles but I'm not sure that's completely what I'm after as I can't display stuff such as Django forms for example.
EDIT: Kind of like how a CMS works but without the users/group stuff and be able to use Django View modules such as forms.
Any advice?
Thanks
