djangocms-spa-vue-js 0.1.29

This package prepares your django CMS and vue.js project to create a single-page application (SPA).

This package prepares your django CMS and vue.js project to create a single-page application (SPA). Use it together with the base package djangocms-spa.

A template tag renders a list of all available routes that are used by vue-router. Contents of other pages are requested asynchronously and delivered as JSON through a REST-API.

Make sure you read the docs of djangocms-spa.

Quickstart

Install djangocms-spa-vue-js:

pip install djangocms-spa-vue-js

Add it to your INSTALLED_APPS:

INSTALLED_APPS = (
    ...
    'djangocms_spa',
    'djangocms_spa_vue_js',
    ...
)

Add the URL pattern form the API:

urlpatterns = [
    ...
    url(r'^api/', include('djangocms_spa.urls', namespace='api')),
    ...
]

Render your vue.js router in your template:

{% load router_tags %}
{% vue_js_router %}

Apphooks

You need to consider a couple of things when using apphooks. Let’s assume you have an event model.

class Event(DjangocmsVueJsMixin):
    name = models.CharField(max_length=255, verbose_name=_('Name'))

    def get_frontend_list_data_dict(self, request, editable=False, placeholder_name=''):
        # Returns the data for your list view.
        data = super(Event, self).get_frontend_list_data_dict(request=request, editable=editable, placeholder_name=placeholder_name)
        data['content'].update({
            'name': self.name,
        })
        return data

    def get_frontend_detail_data_dict(self, request, editable=False):
        # Returns the data for your detail view.
        data = super(Event, self).get_frontend_detail_data_dict(request, editable)

        # Prepare the content of your model instance. We use the same structure like the placeholder data of a CMS page.
        content_container = {
            'type': 'generic',
            'content': {
                'name': self.name
            }
        }

        # Add support for the CMS frontend editing
        if editable:
            content_container.update(
                self.get_cms_placeholder_json(request=request, placeholder_name='cms-plugin-events-content')
            )

        # Put the data inside a container like any other CMS placeholder data.
        data['containers']['content'] = content_container

        return data

    def get_absolute_url(self):
        # Return the URL of your detail view.
        return reverse('event_detail', kwargs={'pk': self.pk})

    def get_api_detail_url(self):
        # Return the API URL of your detail view.
        return reverse('event_detail_api', kwargs={'pk': self.pk})

    def get_detail_view_component(self):
        # Return the name of your vue component.
        return 'cmp-event-detail'

    def get_detail_path_pattern(self):
        # Return the path pattern of your named vue route.
        return 'events/:pk'

    def get_url_params(self):
        # Return the params that are needed to access your named vue route.
        return {
            'pk': self.pk
        }

All of your views need to be attached to the menu, even if they are not actually rendered in your site navigation. If the CMS page holding your apphook uses a custom view, you need this configuration:

DJANGOCMS_SPA_VUE_JS_APPHOOKS_WITH_ROOT_URL = ['<my_apphook_name>']

Your cms_menus.py might looks like this:

class EventMenu(CMSAttachMenu):
    name = _('Events')

    def get_nodes(self, request):
        nodes = []
        counter = 1
        is_draft = self.instance.publisher_is_draft
        is_edit = hasattr(request, 'toolbar') and request.user.is_staff and request.toolbar.edit_mode

        # We don't want to parse the instance in live and draft mode. Depending on the request user we return the
        # corresponding version.
        if (not is_edit and not is_draft) or (is_edit and is_draft):
            # Let's add the list view
            nodes.append(
                NavigationNode(
                    title='Event List',
                    url=reverse('event_list'),
                    id=1,
                    attr={
                        'component': 'cmp-event-list',
                        'vue_js_router_name': 'event-list',
                        'fetch_url': reverse('event_list_api'),
                        'absolute_url': reverse('event_list'),
                        'named_route_path_pattern': ':pk',  # Used to group routes (dynamic route matching)
                        'login_required': True  # Hide a navigation node for unauthorized users
                    }
                )
            )
            counter += 1

            for event in Event.objects.all():
                nodes.append(
                    NavigationNode(
                        title=event.name,
                        url=event.get_absolute_url(),
                        id=counter,
                        attr=event.get_cms_menu_node_attributes(),
                        parent_id=1
                    )
                )
                counter += 1

        return nodes

menu_pool.register_menu(EventMenu)

This is an example of a simple template view. Each view that you have needs an API view that returns the JSON data only.

from djangocms_spa.views import SpaApiView
from djangocms_spa_vue_js.views import VueRouterView

class ContentMixin(object):
    template_name = 'index.html'

    def get_fetched_data(self):
        data = {
            'containers': {
                'content': {
                    'type': 'generic',
                    'content': {
                        'key': 'value'
                    }
                }
            }
        }
        return data


class MyTemplateView(ContentMixin, VueRouterView):
    fetch_url = reverse_lazy('content_api')  # URL of the API view.


class MyTemplateApiView(ContentMixin, SpaApiView):
    pass

Your list view looks like this:

from djangocms_spa.views import SpaListApiView
from djangocms_spa_vue_js.views import VueRouterListView

class EventListView(VueRouterListView):
    fetch_url = reverse_lazy('event_list_api')
    model = Event
    template_name = 'event_list.html'


class EventListAPIView(SpaListApiView):
    model = Event
    template_name = 'event_list.html'

Your detail view looks like this:

from djangocms_spa.views import SpaDetailApiView
from djangocms_spa_vue_js.views import VueRouterDetailView

class EventDetailView(VueRouterDetailView):
    model = Event
    template_name = 'event_detail.html'

    def get_fetch_url(self):
        return reverse('event_detail_api', kwargs={'pk': self.object.pk})


class EventDetailAPIView(SpaDetailApiView):
    model = Event
    template_name = 'event_detail.html'

The router object

The server needs to prepare the routes for the frontend. The easiest way to do this is by iterating over the CMS menu. In order to bring all available routes to the menu, you have to register all your custom URLs as a menu too. A template tag renders a JS object like this.

{
    "routes": [
        {
            "api": {
                "fetch": "/api/pages/",
                "query": {
                    "partials": ["menu", "footer"]
                }
            },
            "component": "index",
            "name": "cms-page-1",
            "path": "/"
        },
        {
            "api": {
                "fetched": {
                    "partials": {
                        "menu": {
                            "type": "generic",
                            "content": {
                                "menu": [
                                    {
                                        "path": "/",
                                        "label": "Home",
                                        "children": [
                                            {
                                                "path": "/about",
                                                "label": "About",
                                                "children": [
                                                    {
                                                        "path": "/contact",
                                                        "label": "Contact"
                                                    }
                                                ]
                                            }
                                        ]
                                    }
                                ]
                            }
                        },
                        "footer": {
                            "type": "cmp-footer",
                            "plugins": [

Debugging

If you need to debug the router object, this middleware is probably pretty helpful:

MIDDLEWARE += (
    'djangocms_spa_vue_js.middleware.RouterDebuggingMiddleware',
)
