CRUD in Sinatra -- Check for Understanding

cfu_crud_in_sinatra.markdown

1. Define CRUD. CRUD stands for Create, Read, Update, and Delete. These are the main functions that we can do to data.
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. get + /tasks: Read all tasks get + /tasks/:id: Read specific task get + /tasks/new: get form to fill out new task post + /tasks: Create a new task get + /tasks/:id/edit: See form to edit task info put + /tasks/:id: change task delete + /tasks/:id: delete a task
3. Why do we use set method_override: true? Because we need to overwrite post with put and delete
4. Explain the difference between value and name in this line: <input type='text' name='task[title]' value="<%= @task.title %>"/>. the name field denotes the name of the variable stored in the database, the value is the value stored in the particular name field.
5. What are params? Where do they come from? That is what is sent by the forms

Looks good. Just a note - the name field in the input of the form is what will defined the name of the key in the params hash, we write it so it represents something in a database, but it doesn't 'have to be' something in the database
