Step 7 : Generate a database model
Phoenix gives us a phoenix.gen.html task similar to Rails
rails generate scaffold
Now that the database has been created with
mix ecto.create, type this into the terminal:
mix phoenix.gen.html Drink drinks name:string temperature:string
You should see output similar to this:
* creating web/controllers/drink_controller.ex * creating web/templates/drink/edit.html.eex * creating web/templates/drink/form.html.eex * creating web/templates/drink/index.html.eex * creating web/templates/drink/new.html.eex * creating web/templates/drink/show.html.eex * creating web/views/drink_view.ex * creating test/controllers/drink_controller_test.exs * creating web/models/drink.ex * creating test/models/drink_test.exs * creating priv/repo/migrations/20160828191433_create_drink.exs Add the resource to your browser scope in web/router.ex: resources "/drinks", DrinkController Remember to update your repository by running migrations: mix ecto.migrate
Now let’s follow the instructions at the end of that output.
We’ll add routes. Open up a file named ‘web/router.ex’
Around line 19 (this will vary depending on your editor)
delete the section that looks like
scope "/", TestApp do pipe_through :browser # Use the default browser stack get "/", PageController, :index resources "/pages", PageController end
and paste in the following
scope "/", TestApp do pipe_through :browser # Use the default browser stack get "/", DrinkController, :index resources "/drinks", DrinkController end
so that section should now look like this
scope "/", ElixirBlog do pipe_through :browser # Use the default browser stack get "/", DrinkController, :index resources "/drinks", DrinkController end
now type this into the terminal
You will see something similar to the following on your screen
Now lets start our server up again
Type the following into the terminal
Then go to your browsers and type in localhost:4000
You should see a page that looks something like this
Wait till your server has loaded like before.
Then in the browser url bar type in:
1) Click on new drink
2) Enter Cappuccino for the name
3) Enter 135 for the temperature.
4) Click on “Create Drink”.
You should see the following text at the top of the page
Go on to Deploy a Phoenix App.
Go back to Create a Phoenix App.
