rails blog to generate app
./script/server to run the server locally
./script/generate controller to run the blog (router and views)
create index action render "hello world" text
app/views/blog/index.rhtml template - automatically renders with no handler
create posts table with id and title
./script/generate model
./script/generate model Post
scaffold :post - putting model object online to edit -> CRUD views
add body text field -> added to all views automatically without restarting or compiling, all happens at runtime!
validation, ie "non null" in model and shown in the ui
./script/generate scaffold Post Blog
- a bunch of generated actions. this is compiling out what scaffold :post was doing at runtime to static code
- Edits the template to look how we want
- "People learn by changing a little thing. Reloading and seeing the change"
- link_to methods we can call in the view
- changed the index view to be pretty, the other create and view and edit routes look the same for now
- reverse the list in /
textile markup language for text
extract _post.rhtml template to render partials for collections in /
in the show page, render the partial
./script/generate model Comment
- Post has_many :comments
- in db UI, create comments table, post_id - rails figures out that's the foreign key
- manually creates a new commend in the db ui
in the show page
- loop over the @post.comments in the show.rhtml page
- create comment form
- comment action in the blog controller, find the one with id (specify in the form)
- flash "notice" at the top of the screen is funky
rake stats to see how much code we create - "58 lines of code"
look at the logs to see the sql being generated ("because we didn't write any sql")
run the tests, two tests passing for the 2 model objects - adds a comment and then checks if the post has a comment (after "reloading the object")
./script/console
