Views

The Avo CRUD feature generates with four main views for each resource.

-> Index

The page where you see all your resources listed in a table or a grid.

-> Show

The page where you see one resource in more detail.

-> Edit

The page where you can edit one resource.

-> New

The page where you can create a new resource.

Preview

The fields marked with show_on :preview, will be show in the preview field popup. By default, all fields are hidden in :preview.

Checking the current view

The view object, available in the code, is an instance of the Avo::ViewInquirer class. This enables you to examine the existing view status through expressions such as view.show? and view.index?. Essentially, these are equivalent to asserting whether view equals show or index.

Multiple ways to check

view == "edit" # Check against a string
view == :edit # Check against a symbol
view.edit? # Ask if it's a view
view.form? # Ask if it's a collection of views
view.in? [:edit, :new] # Check against an array of symbols
view.in? ["edit", "new"] # Check against an array of strings

Ask

if view.show?
  # Code for the "show" view
elsif view.index?
  # Code for the "index" view
elsif view.edit?
  # Code for the "edit" view
elsif view.new?
  # Code for the "new" view
elsif view.form?
  # Code for the "new" or "edit" views
elsif view.display?
  # Code for the "index or "show" views
end

Symbol comparator

if view == :show
  # Code for the "show" view
elsif view == :index
  # Code for the "index" view
elsif view == :edit
  # Code for the "edit" view
elsif view == :new
  # Code for the "new" view
end

String comparator

if view == "show"
  # Code for the "show" view
elsif view == "index"
  # Code for the "index" view
elsif view == "edit"
  # Code for the "edit" view
elsif view == "new"
  # Code for the "new" view
end

It's also possible to check if the view is on a form (new, edit) or display (index, show).

Ask

if view.form?
  # Code for the "new" and "edit" views
elsif view.display?
  # Code for the "show" and "index" views
end

Symbol comparator

if view.in? [:new, :edit]
  # Code for the "new" and "edit" views
elsif view.in? [:show, :index]
  # Code for the "show" and "index" views
end

String comparator

if view.in? ["new", "edit"]
  # Code for the "new" and "edit" views
elsif view.in? ["show", "index"]
  # Code for the "show" and "index" views
end
