At the time of writing there are four extensions: ▸ Add more to your website ▸ Extending the base built (ﬁlters, delete) ▸ Secure your website ▸ Adding authorisation ▸ Create a comment model ▸ Adding a new model ▸ PostgresSQL installation
All perfectly acceptable ▸ The industry moves at a fast space ▸ If you aren’t evolving your skill set you will get left behind ▸ Two things stood out to me when reviewing the tutorials ▸ No testing ▸ No ‘services’ offered
can use any library you want ▸ Its very important to add tests. It is the one true metric that separates a ‘good’ developer from a ‘bad’ one. ▸ Its not up for debate. ▸ Learn how to test your app in django. There are hundreds of pages on this subject.
REST API using an API KEY. ▸ Tastypie has a builtin API Key gen. ▸ We use by adding a signal for the User object. ▸ When a user is created it will generate an API key. ▸ So create `services/apps.py` # services/apps.py from django.apps import AppConfig from django.contrib.auth.models import User from django.db.models import signals from tastypie.models import create_api_key class ServiceConfig(AppConfig): name = "services" def ready(self): signals.post_save.connect(create_api_key, sender=User)
in TastyPie ▸ Deﬁning a resource will convert the model into an API Stream ▸ Allows us to validate requested data ▸ Modifying a response before sending onto a client # services/api.py from tastypie.resources import ModelResource from .models import Post class PostResource(ModelResource): class Meta: queryset = Post.objects.all() resource_name = 'post' allowed_methods = ['get']
client consume our API # services/urls.py from django.conf.urls import url, include from tastypie.api import Api from services.api import PostResource v1_api = Api(api_name='v1') v1_api.register(PostResource()) urlpatterns = [url(r'^api/', include(v1_api.urls))] ▸ Include the URL in the project’s URL dispatcher. Note I took away the previous blog.url # mysite/urls.py from django.conf.urls import include, url from django.contrib import admin urlpatterns = [ url(r'^admin/', include(admin.site.urls)), url(r'', include(“services.urls")), ]
