Create Article CRUD Routes

[Bryan Wong]

Is your feature request related to a problem? Please describe.
We need to implement CRUD routes for Articles to allow them to be created, updated, deleted, and searched.

Describe the solution you'd like
Routes need to be created:

• CreateArticle - /api/articles POST
• FetchArticles - /api/articles GET
• UpdateArticle - /api/articles/<int:article_id> PUT
• DeleteArticle - /api/articles/<int:article_id> DEL
• FetchArticle - /api/articles/<int:article_id> GET

Routes/functions to implement/change
Should create a ArticleCrud class to implement the CRUD routes with Flask-Restful
example:

class ModelCRUD(Resource):
    def get(self):
    def post(self):
    def put(self):
    def delete(self):

Additional context

• CreateArticle: When creating an Article, validate it with the ArticleFormSchema. Create a function called create_article in utils.py in the articles folder. The function should create the Article and return it. In the route call the create_article function, add it to the db session and commit it. If successful, return:

{
	"message": "Successfully created Article"
}, 201

• UpdateArticle: Update an Article by first validating the form data with the ArticleFormData schema. Query for the Article by the id given in the route. Create a function called update_article in utils.py in the articles folder it should take in the Article and form data as parameters. The function should update the Article's parameters. If successful, return:

{
	"message": "Article successfully updated"
}, 200

• DeleteArticle: Query for the Article by id. Use db.session.delete() to delete the object. If successful, return:

{
	"message": "Article successfully deleted"
}, 200

• FecthArticle: Query for the Article by id. Return the serialization with ArticleSchema.
• FetchArticles: Query for a maximum of 15 Articles and serialize and return it with ArticlesSchema
