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.

• GET /all - shows everything created
• GET /all/specific - shows a specific thing created
• GET /all/new - gives form to create something new
• POST /all - creates something new
• GET /all/specific/edit - shows something that has already been created but needs to be changed
• PUT /all/sepcific - makes changes
• DELETE /all/specific - deletes

3. Why do we use set method_override: true? -This allows us to override the standard post method when we need to make a PUT or DELETE request using _method
4. Explain the difference between value and name in this line: <input type='text' name='task[title]' value="<%= @task.title %>"/>.

• name is assigning the param and value is filling in the form

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

• params are key value pairs that come in from a post request or from the end of a url path

5. Mostly correct 😄 The params can come from the middle of the path if the dynamic parameter is there. For example: /tasks/:id/edit -- :id is the dynamic parameter.
