Is there a way to get query params from page?

[zw963]

What i want to is, get query params, e.g. params["q"], like "/universities?q=foo",and fill the foo into the search box when refresh the code.

Thanks

You can use expose for this case. https://luckyframework.org/guides/frontend/rendering-html#example-using-needs-and-expose

class FooAction < BrowserAction
  param q : String
  expose query_param

  get "/universities" do
    html FooPage
  end

  private def query_param
    q
  end
end

class FooPage < MainLayout
  needs query_param : String

  def content
    h1 query_param
  end
end

Hi, i found i can get query_params use context.request.query_params["q"] in page directly, this way is a little simple then pass from action, furthermore, latter have to create a method.
