Dated queries in Badgeyay admin

Badgeyay is not just an anonymous badge generator that creates badges according to your needs, but it now has an admin section that allows the admin of the website to control and look over the statistics of the website.

Why do we need such an API?

For an admin, one of the most common functionality is to gather the details of the users or the files being served onto or over the server. Not just that, but the admin must also be aware about the traffic or files on the server in a particular duration of time. So we need an API that can coordinate all the stuff that requires dated queries from the backend database.

Adding the functionality to backend

Let us see how we implemented this functionality into the backend of the project.

Step 1 : Adding a route

This step involves adding a separate route that provides us with the output of the dated badges queries from backend.

@router.route(‘/get_badges_dated’, methods=[‘POST’])
def get_badges_dated():
schema = DatedBadgeSchema()
input_data = request.get_json()
data, err = schema.load(input_data)
if err:
return jsonify(err)
dated_badges = Badges.query.filter(Badges.created_at <= data.get(
‘end_date’)).filter(Badges.created_at >= data.get(‘start_date’))
return jsonify(AllBadges(many=True).dump(dated_badges).data)

This route allows us to get badges produced by any user during a certain duration as a JSON API data object. This object is fed to the frontend to render the badges as cards.

Step 2 : Adding a relevant Schema

After creating a route we need to add a relevant schema that will help us to deliver the badges generated by the user to the Ember JS frontend so that it can be consumed as JSON API objects and shown to the user.

class DatedBadgeSchema(Schema):
class Meta:
type_ =
‘dated-badges’
kwargs = {
‘id’: ‘<id>’}

id = fields.Str(required=True, dump_only=True)
start_date = fields.Date(required=
True)
end_date = fields.Date(required=
True)

class AllBadges(Schema):
class Meta:
type_ =
‘all-badges’
self_view =
‘admin.get_all_badges’
kwargs = {
‘id’: ‘<id>’}

id = fields.Str(required=True, dump_only=True)
image = fields.Str(required=
True)
csv = fields.Str(required=
True)
badge_id = fields.Str(required=
True)
text_color = fields.Str(required=
True)
badge_size = fields.Str(required=
True)
created_at = fields.Date(required=
True)
user_id = fields.Relationship(
self_url=
‘/api/upload/get_file’,
self_url_kwargs={
‘file_id’: ‘<id>’},
related_url=
‘/user/register’,
related_url_kwargs={
‘id’: ‘<id>’},
include_resource_linkage=
True,
type_=
‘User’
)

This is the DatedBadge schema that produces the output results of the POST request on the route. And there is the AllBadges schema that produces the output results of the POST request on the route.

Further Improvements

We are working on adding multiple routes and adding modifications to database models and schemas so that the functionality of Badgeyay can be extended to a large extent. This will help us in making this badge generator even better.

Get My Badges from Badgeyay API

Badgeyay is no longer a simple badge generator. It has more cool features than before.

Badgeyay now supports a feature that shows your badges. It is called ‘my-badges’ component. To get this component work, we need to design a backend API to deliver the badges produced by a particular user.

Why do we need such an API?

The main aim of Badgeyay has changed from being a standard and simple badge generator to a complete suite that solves your badge generation and management problem. So to tackle the problem of managing the produced badges per user, we need to define a separate route and schema that delivers the generated badges.

Adding the functionality to backend

Let us see how we implemented this functionality into the backend of the project.

Step 1 : Adding a route

This step involves adding a separate route that provides with the generated output of the badges linked with the user account.

@router.route(‘/get_badges’, methods=[‘GET’])
def get_badges():
input_data = request.args
user = User.getUser(user_id=input_data.get(
‘uid’))
badges = Badges().query.filter_by(creator=user)
return jsonify(UserBadges(many=True).dump(badges).data)

This route allows us to get badges produced by the user as a JSON API data object. This object is fed to the frontend to render the badges as cards.

Step 2 : Adding a relevant Schema

After creating a route we need to add a relevant schema that will help us to deliver the badges generated by the user to the Ember JS frontend so that it can be consumed as JSON API objects and shown to the user.

class UserBadges(Schema):
class Meta:
type_ =
‘user-badges’
self_view =
‘generateBadges.get_badges’
kwargs = {
‘id’: ‘<id>’}

id = fields.Str(required=True, dump_only=True)
image = fields.Str(required=
True)
csv = fields.Str(required=
True)
badge_id = fields.Str(required=
True)
text_color = fields.Str(required=
True)
badge_size = fields.Str(required=
True)
user_id = fields.Relationship(
self_url=
‘/api/upload/get_file’,
self_url_kwargs={
‘file_id’: ‘<id>’},
related_url=
‘/user/register’,
related_url_kwargs={
‘id’: ‘<id>’},
include_resource_linkage=
True,
type_=
‘User’
)

This is the ‘UserBadge’ schema that produces the output results of the GET request on the route.

Finally, once this is done we can fire up a GET request on our deployment to receive results. The command that you need to run is given below.

$ ~ curl -X GET http://localhost:5000/api/get_badges?uid={user_id}
