# Views
|
|
|
|
You can use ERB-like built-in **ECR** views to render files.
|
|
|
|
```crystal
|
|
get '/:name' do
|
|
render "views/hello.ecr"
|
|
end
|
|
```
|
|
|
|
And you should have an `hello.ecr` view. It will have the same context as the method.
|
|
|
|
```erb
|
|
Hello <%= env.params["name"] %>
|
|
```
|
|
|
|
## Using Layouts
|
|
|
|
You can use **layouts** in Kemal. You should pass a second argument.
|
|
|
|
```crystal
|
|
get '/:name' do
|
|
render "views/subview.ecr", "views/layouts/layout.ecr"
|
|
end
|
|
```
|
|
|
|
And you should use `content` variable (like `yield` in Rails) in layout file.
|
|
|
|
```erb
|
|
<html>
|
|
<head>
|
|
<title><%= $title %></title>
|
|
</head>
|
|
<body>
|
|
<%= content %>
|
|
</body>
|
|
</html>
|
|
```
|
|
|
|
## Using Common Paths
|
|
|
|
Since Crystal does not allow using variables in macro literals, you need to generate
|
|
another *helper macro* to make the code easier to read and write.
|
|
|
|
```crystal
|
|
macro my_renderer(filename)
|
|
render "my/app/view/base/path/#{{{filename}}}.ecr", "my/app/view/base/path/layouts/layout.ecr"
|
|
end
|
|
```
|
|
|
|
And now you can use your new renderer.
|
|
|
|
```crystal
|
|
get '/:name' do
|
|
my_renderer "subview"
|
|
end
|
|
```
