Render HEEX template with given (root) layout to string
Hello,
I would like to ask, if there is a better way to render .html.heex files to string WITH layouts?
My use case is that in controller I need raw HTML to later process into PDF.
Here, building on top of the starter project, I have a working solution (by rendering page and layout myself):
defmodule PhoenixTemplatesPocWeb.PageController do
use PhoenixTemplatesPocWeb, :controller
alias PhoenixTemplatesPocWeb.Layouts
alias PhoenixTemplatesPocWeb.PageHTML
def home(conn, _params) do
# The home page is often custom made,
# so skip the default app layout.
render(conn, :home, layout: false)
end
def home_pdf(conn, _params) do
rendered_content =
%{}
|> PageHTML.home_pdf()
|> Phoenix.HTML.Safe.to_iodata()
|> IO.iodata_to_binary()
rendered_pdf =
%{
inner_content: rendered_content
}
|> Layouts.root_pdf()
|> Phoenix.HTML.Safe.to_iodata()
|> IO.iodata_to_binary()
text(conn, rendered_pdf)
end
end
Thanks.
