How to enable frontend editing in Django CMS?

How to enable frontend editing in Django CMS? How exactly do I enable front end editing in Django CMS 3.5.2? I added this to the top of my template: {% load cms_tags menu_tags sekizai_tags static %} and I added {% placeholder "content" %} to the body. This works in the sense that I can use it in the structure toolbar but it doesn't show up as an editable field when I hover the mouse over it. I don't want to use {% render_model ... %} as I'm not creating a new model. I know how to use Django but its not helping me much here as DjangoCMS doesn't make it obvious what variables are passed into the template. Please, How do I go about this? Have you remembered to include {% cms_toolbar %} straight after the <body> tag? – markwalker_ Jul 1 at 10:57 {% cms_toolbar %} <body> ...

static files not loading only on django admin page

static files not loading only on django admin page This is on a production server with DEBUG = False. My static files will load on the home page but not the admin page. It gives me a error 404 in the browser console. This only happens on the admin page. I've checked to make sure that the .css files are in the specified directory's and they are along with the code inside them. NOTE: The same server and file structure was working earlier. I've tried almost everything I can think of any help would be greatly appreciated!

Django persist ModelMultipleChoiceField selections

Django persist ModelMultipleChoiceField selections I have a ModelMultipleChoiceField that allows a user to select one or more of a set of my "community" model (akin to a user joining a subreddit). When the user reopens the page to select communities, there are no checkboxes on the fields that the user has selected before. I would like to make it so that previously selected communities stay with check boxes, and therefore when the user hits submit their previous choices won't be forgotten if they don't reselect the previous choices. Here is my form: class CustomChoiceField(forms.ModelMultipleChoiceField): def label_from_instance(self, obj): return obj.name class CommunitySelectForm(forms.ModelForm): community_preferences = CustomChoiceField(queryset=Community.objects.all(), widget=forms.CheckboxSelectMultiple) class Meta: model= UserQAProfile fields = ['community_preferences'] And here is my template: <div class="col-...
