CRUD in Sinatra -- Check for Understanding

cfu_crud_in_sinatra.markdown

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 - /folder) - get all items in folder b. (get - /folder/:id) - get single item in folder c. (get - /folder/new) - get view with form to create new view d. (post - /folder) - post new item e. (get - /folder/:id/edit) - get form to edit exisiting item f. (put - /folder/:id) - update existing item g. (delete - /folder/:id) - delete item based on id

3. Why do we use set method_override: true? - to allow us to give buttons another method instead of POST

4. Explain the difference between value and name in this line: <input type='text' name='task[title]' value="<%= @task.title %>"/>. - name is what is going to be sent when the form is submitted, value is what populates the text field.

5. What are params? Where do they come from? - params come from form submission? i think?

Params come from submitting a form, or they can also be sent through in the url. If you see a ? in a url - it signals the start of params. So - if we have a url like this: www.thingplace.com/places/5?name=ocean&description=wet then we will get params like: params = { "name" => "ocean", "description" => "wet"}
