- Understand how to communicate between client and server using fetch, and how the server will process the request based on the URL, HTTP verb, and request body
- Debug common problems that occur as part of the request-response cycle
Just like the last lesson, we've got code for a React frontend and Rails API backend set up. This time though, it's up to you to use your debugging skills to find and fix the errors!
To get the backend set up, run:
$ bundle install
$ rails db:migrate db:seed
$ rails s
Then, in a new terminal, run the frontend:
$ npm install --prefix client
$ npm start --prefix client
Confirm both applications are up and running by visiting
localhost:4000
and viewing the list of toys in your
React application.
In this application, we have the following features:
- Display a list of all the toys
- Add a new toy when the toy form is submitted
- Update the number of likes for a toy
- Donate a toy to Goodwill (and delete it from our database)
The code is in place for all these features on our frontend, but there are some problems with our API! We're able to display all the toys, but the other three features are broken.
Use your debugging tools to find and fix these issues.
There are no tests for this lesson, so you'll need to do your debugging in the
browser and using the Rails server logs and byebug
.
Note: You shouldn't need to modify any of the React code to get the application working. You should only need to change the code for the Rails API.
As you work on debugging these issues, use the space in this README file to take notes about your debugging process. Being a strong debugger is all about developing a process, and it's helpful to document your steps as part of developing your own process.
-
Add a new toy when the toy form is submitted
- How I debugged: seeing what happened when i clicked the add toy button on the frontend and looking in the network area for any logs of what was happening noticing there was an error originating from the server checking the server side for the error and correcting it from Toys.create to Toy.create
-
Update the number of likes for a toy
- How I debugged: clicking the like button then checking the network area to see what is going on in the backend seeing the likes were not properly updating the database then correcting it
-
Donate a toy to Goodwill (and delete it from our database)
- How I debugged: clicking the donate button then checking the network area seeing that the route was not defined in the backend adding the route then testing the donate button
