API Muncher

Congratulations! You're submitting your assignment!

Comprehension Questions

Question	Answer
How did you go about exploring the Edamam API, how did you try querying the API?	I used Edamam docs to figure out the structure of the API call and then Postman to parse the JSON
Describe your API Wrapper. How did you decide on the methods you created?	The wrapper has methods list the recipes and then find a recipe. These allow for one location that parses the JSON in case data structure changes in the future we can just change it in one place. How I decided, I looked at the Edamam docs and saw there were two applicable queries (q= and r=) and build the methods based on that. In addition I used slack-api as an example.
Describe an edge case or failure case test you wrote for your API Wrapper.	I gave the url a bogus API token and raised an ApiError when the request failed.
Explain how VCR aids in testing an API.	It records the JSON data in a yml file. By recording it we can use it instead of making costly API calls for each test run.
What is the Heroku URL of your deployed application?	https://fathomless-hollows-55266.herokuapp.com/

What We're Looking For

Feature	Feedback
Core Requirements
Git hygiene	yes
Comprehension questions	yes
General
Rails fundamentals (RESTful routing, use of named paths)	yes
Semantic HTML	yes
Errors are reported to the user	some - You've got the `flash` reporting section in `application.html.erb` set up nicely, but I was not able to get it to actually display a message for me. Make sure you're detecting error cases accurately, and actually reporting problems to the user.
API Wrapper to handle the API requests	yes
Controller testing	Good start, especially around show, but there's still some pieces missing here. See inline.
Lib testing	yes
Search Functionality	yes
List Functionality	yes
Show individual item functionality (link to original recipe opens in new tab)	yes
Styling
Foundation Styling for responsive layout	yes
List View shows 10 items at a time/pagination	yes
The app is styled to create an attractive user interface	yes
API Features
The App attributes Edaman	yes
The VCR casettes do not contain the API key	yes
External Resources
Link to Trello Board	yes
Link to deployed app on Heroku	yes
Overall	Good job overall! It seems like you've got a solid grasp on the core learning goals for this assignment. One area worth focusing on going forward is error handling, and making sure that errors are plumbed all the way from the source (in this case an API call) to being displayed to a user. There were a few cases where there was a disconnect, and valuable information ended up being lost. Fixing this means knowing whether a method throws an exception, returns a sentinel value like `nil`, or returns something like an empty array, and being able to handle it appropriately wherever the method is called. This sort of information also manifests when coming up with test cases, which is a big portion of why we study testing in this course. Other than that I'm pretty happy with this submission. Keep up the hard work!

app/controllers/recipes_controller.rb

+  def index
+    @query = params[:search]
+
+    if params[:search]


Because the empty string is truthy in Ruby, even if you search for nothing you won't end up in the error handling here. Instead, you might have something like if params[:search] && params[:search] != "".

app/controllers/recipes_controller.rb

+
+  def new
+
+  end


I don't think the new action is used in your app.

droberts-sea · 2017-11-08T21:15:21Z

app/controllers/recipes_controller.rb

+
+    unless @recipe
+      head :not_found
+    end


I like this idea, but I do not believe the code will ever get here. Your API wrapper throws an error if the recipe is not found, but here you check for a nil response. You have two options to make the connection:

Use a begin/rescue block here to catch the exception

Instead of throwing an error, return nil from ApiWrapper.find_recipe if the recipe can't be found.

droberts-sea · 2017-11-08T21:18:48Z

lib/api_wrapper.rb

+
+
+    # parse the JSON data in order to get recipe details for the show page
+    if data.empty?


It looks like you're missing a call to check_status here. If the API returns an error like not_authed (as opposed to no results), as is this method won't be able to detect it.

droberts-sea · 2017-11-08T21:27:21Z

test/controllers/recipes_controller_test.rb

+      #    #
+       #
+      #    get recipe_path params: { search: "chicken", url: "http://www.edamam.com/ontologies/edamam.owl%23recipe_637913ec61d9da69eb451818c3293df2" + "fake-url"}
+      #    must_respond_with :not_found


I think this test is failing because the controller action is handling the error incorrectly. See comments above.

test/lib/api_wrapper_test.rb

+      begin # something which might raise an exception
+        origin_token = ApiWrapper::TOKEN
+        ApiWrapper::TOKEN = "bogus_token"
+        VCR.use_cassette("recipes") do


I like this way of testing an invalid token - much simpler than what we did in class.
