Extract Partial
This feature is supported only when the Ruby plugin is installed.
Basics
The Extract Partial refactoring enables you to break rendering of a certain view into smaller chunks, and applies to *.html.erb and *.html.haml files.
This way, you can extract blocks of code from a view into a partial view, and replace them with a call. So doing, IntelliJ IDEA generates the name for the resulting partial view on the base of the user input in accordance with the Rails naming conventions: if the suggested partial view name is bar, the generated name is _bar.html.erb or _bar.haml.
Example
| Before | After |
|---|---|
View foo.html.erb:  | View  Partial view  |
Extracting partial view
To extract partial
- Open a view in the editor.
- Select the desired fragment of valid code. For example, in case of HTML, your selection must contain matching opening and closing tags.
- On the main menu, or on the context menu of the selection, choose .
- In the Extract Partial dialog box, specify the desired partial view name without extension and the leading underscore, and click OK.
