CRUD in Sinatra -- Check for Understanding

cfu_crud_in_sinatra.markdown

1. Define CRUD. All the functionality expected from a database application: create, read, update, delete

2. There are seven verb + path combinations that are necessary in a basic Sinatra app in order to provide full CRUD functionality. List each of the seven combinations, and explain what each is for.

3. get /tasks shows all of the tasks

4. get /tasks/:id shows a single task

5. get /tasks/new show form to make a new task

6. post /tasks makes a new task

7. get /tasks/:id/edit shows form to update a task

8. put /tasks/:id updates a specific task

9. delete /tasks/:id deletes a task

10. Why do we use set method_override: true? It lets us use hidden methods to replace a post with put or delete

11. Explain the difference between value and name in this line: <input type='text' name='task[title]' value="<%= @task.title %>"/>. Name is what the input is called, while value is the content of the input box that the user sees

12. What are params? Where do they come from? Params are information from the request; they are in the url for a get and are in the body for a post.
