Sinatra Assessment Prep 👨🏻‍💻 👩🏻‍💻

By ChiEn Leow, Alicia Reeves

Possible Assessment Questions:

• Write a migration to modify an existing table (creating migration, creating new model, adding to schema, understanding the convention, relationships)

• Tux

• How to authenticate users, bycrpt, has_secure_password

• How objects are created, sending request (form), http verbs (post, patch)

• Routes are protected (users cannot edit/delete others)

• Difference between authentication (email, password) and authorization (what a user can do)

• What is ActiveRecord:Base? It builds all your macro methods for you.

• Write a helper method

My Review (ChiEn):

1. Sign up a user, show in browser then explain in code

2. Try signing in as user, first try without entering a password, show error message, explain in code, can we use @user.password to check instead of @user.authenticate? Why or why not?

3. Successfully signed in, show CRUD in browser, then explain in code

4. Instructor helped refactor code to use method .build

5. Try editing and deleting other users' projects

6. Create a new model, add table, make sure to include "foreign id" in another table that relates to this table.

My Review (Alicia):

1. Request/response flow

   • What does that mean to you?

   • How does a get request work, how does a post request work? What are the differences?

2. Rendering vs Redirecting

   • What does this mean to you?

3. When logging in, I saw that you set a session[user_id] = @user.id

   • What does this mean to you? What is the session in a Sintra app?

4. has_secure_password

   • What is it really? Read up on the lessons about bcrypt. (or, google bcyrpt and see if an article elsewhere explains it better than flatiron does)

5. And of course, ActiveRecord

   • What is it? What does it afford you? (its a little more than just writing SQL for you). See if you can watch some videos on the topic.

6. Had me create a new object in Tux and associate it with a user. Then walked me through the .build method(as stated above)
