Having trouble with the Parsing the Request - Ingredients challenge
The API needs to be able to validate input from users. Use reqparse and add arguments for each field in the Ingredient model to the IngredientList resource. Remember to add the RequestParser instance to the resource instance as self.reqparse.
name, description, and measurement_type should all be strings (the default) quantity should be a normal Python float recipe should be positive, which you'll get from inputs They should all be required and have their location set to ["form", "json"].
I believe my code is right, but for some reason im getting an error
from flask import Blueprint from flask.ext.restful import Resource, Api, reqparse, inputs import models class IngredientList(Resource): def __init__(self): self.reqparse = reqparse.RequestParser() self.reqparse.add_argument( 'name', required=True, help = 'no data provided', location = ['form', 'json'] ) self.reqparse.add_argument( 'description', required=True, help = 'no data provided', location = ['form', 'json'] ) self.reqparse.add_argument( 'quantity', required=True, help = 'no data provided', type = float, location = ['form', 'json'] ) self.reqparse.add_argument( 'measurement_type', required=True, help = 'no data provided', location = ['form', 'json'] ) self.reqparse.add_argument( 'recipe', required=True, help = 'no data provided', type = inputs.positive, location = ['form', 'json'] ) def get(self): return 'IngredientList' class Ingredient(Resource): def get(self, id): return 'Ingredient' ingredients_api = Blueprint('resources.ingredients', __name__) api = Api(ingredients_api) api.add_resource(IngredientList, '/api/v1/ingredients') api.add_resource(Ingredient, '/api/v1/ingredients/<int:id>')
