12.1 Controllers/Views

Let’s make a controller named article:

art draw controller article show edit

show and edit are the name of methods for the controller named article.

This will generate both a controller and a view for article:

drawing    controller article
working    Controllers `article.scm'
create     app/controllers/article.scm
working    Views `article'
create     app/views/article/show.html.tpl
create     app/views/article/edit.html.tpl

These three files are generated:


Based on this, the controller article will have two methods mapped to the URL rule, show and edit. As part of the view component. An HTML template is generated for each method. For the show method for example, the view file show.html.tpl is created. For the controller component, you get a show method handler, as:

(article-define show
                (lambda (rc)
                  "<h1>This is article#show</h1><p>Find me in app/views/article/show.html.tpl</p>"
                  ;; TODO: add controller method `show'
                  ;; uncomment this line if you want to render view from template
                  ;; (view-render "show")

Of course, you’re free to use or not use these templates. If you want to use the view template, just uncomment the last line (view-render "show").

NOTE: The views template generated by MVC will defaultly announce FreeJS. The reason was well explained in [BROKEN LINK:]. It’s optional, you may remove it with your free will, but I put it there in the hope that you can support free software with us.
