  • Different functionalities and modules used are listed below
  • Here are the API Docs they are being further updated
  • If you like the project please do ⭐ it πŸ˜‡

Repository Structure 🌳

Based on the directories present

  • Model directory contains all the database model class and methods associated

  • Resource directory contains api resource classes

  • Schemas is for the marshmallow schemas

  • Split contains sample code which can help you understand the code base

  • Static is the directory where user images are uploaded

  • Templates conatins html templates

DataBase Architecture πŸ–₯️

There are mainly four schemas 

* Users - which contains details about the users
* Store - which contains details about the store
* Items - which contains details about the items
* Order - which is for ordering stuff

### DataBase Architecture

- store and item : one to many 
- item and order: many to many 

Functionalities present

1) flask_jwt_extended

      access_token = create_access_token(identity=user.id,fresh=True)
      refresh_token = create_refresh_token(user.id)

      return {
          "access_token": access_token,
          "refresh_token": refresh_token
      },200
  • For all post and put methods jwt token is required

  • Deletion requires a fresh jwt token so might prompt you to sign in again

2) flask restful

  • Read about it here

  • Used for creating resource class

  • You can define the endpoints using flask restful

 class Item(Resource):
 
   def get(self):
       try:
           data = item_schema.load(request.get_json())
           print(data.name)
       except ValidationError as err:
           return err.messages,400
       print(data)
       name = data.name
       item = ItemModel.find_by_name(name)

       if item:
           return item_schema.dump(item)
       return {
           "msg": "Item not found"
       }

3) flask marshmallow

  • Read about it here

  • flask marshmallow allows us to easily seralize and desarlize data

  • Check marsh_app.py file under split directory which contains simple example of using flask marshmallow

     class RewardSchema(ma.SQLAlchemyAutoSchema):
         class Meta:
             model = Reward
             load_instance = True

     class MarshSchema(ma.SQLAlchemyAutoSchema):
         rewards = ma.Nested(RewardSchema,many=True)
         class Meta:
             model = Marsh
             load_instance = True
  • The example used above has been similarly implemented in the project

  • flask marshmallow latest version has syantax different from previous versions

  • marshamllow integrates well with SQLAlchemy

4) OAuth2

  • Read about it here

  • For OAuth we are now using GitHub

  • The relevant methods are in github_login file in resource directory

  • Go to Github -> Settings -> Developer settings -> OAuth Apps and get your own client id and secret

  • Populate those values in .env to use github oauth

5) flask migrate

  • Read about it here

  • flask migrate can be used to migrate the database easily

  • app.py under split folder contains sample code

 Command used for migration 

   flask db migrate 

   This does the initial migration and creates the relevant files 

   flask db upgrade 

   This finally upgrades your database

Command used for downgrade

   flask db downgrade
 

6) flask mail

  • Read about it here

  • flask mail allows us to integrate mailing service with flask easily

  • Check mail.py file under split directory which contains simple example to use flask mail

      link = url_for("token_verify",token=tok,_external=True)
      msg.body = "Verify email address by clicking here {}".format(link)
      mail.send(msg)
  • This is used for user confirmation during signup

7) Stripe

  • Read about it here

  • Payments using stripe is integrated within the app

  • Create an account in stripe and generate stripe api keys and add the secret key in .env

  • Test token to make payements is generated using the function

 token=stripe.Token.create(
     card={
         "number": "4242424242424242",
         "exp_month": 9,
         "exp_year": 2021,
         "cvc": "314",
         }, )
  The values given here are all sample values 
  • For performing Indian payments we have to provide the following parameters
 stripe.Charge.create(
           amount=self.amount,
           currency=CURRENCY,
           description=self.description,
           source=token["id"],
