crud.md

1. Define CRUD.

• 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.

• a. GET '/tasks' See all tasks
• b. GET '/tasks/:id' See a single task
• c. GET 'tasks/new' See form to enter a new task
• d. POST '/tasks' Submit data to create a new task
• e. GET '/tasks/:id/edit' Pull up a form (for specific id) in order to edit
• f. PUT '/tasks/:id' Submit data (for specified id) from edit
• g. DELETE '/tasks/:id' Delete a task

3. Why do we use set method_override: true?

• method_override allows us to use PUT and DELETE since GET and POST are the only default verbs.

4. Explain the difference between value and name in this line: <input type='text' name='task[title]' value="<%= @task.title %>"/>.

• The name is outside of the box and is a set value, the value is what appears in the box (our actual data).

5. What are params? Where do they come from?

• Params is a hash that represents our database. Each item inside params is a hash that contains our data.
