Re: GSoC: Adding a web interface similar to the Hydra web interface

[Tatiana Sholokhova]

Hi Ricardo,

Thanks for the helpful answer. Now I almost figured out how to serve static files.

I have committed the first HTML template page (with table of specifications stored in the database) to web-interface branch. Can you please review it?

I am a bit confused about the database structure. As far as I understand, there are project_name (project) and branch_name (jobset) properties, but project_name is a primary key, so a project can't have several branches? 

I'm working on static file serving but I don't know how to set the path of the static file directory. Now I just wrote my absolute path to the style.css file. So, I have two questions. 1. Where should I place the static files? 2. How can I execute getcwd function (as you do it in rcas-web/rcas/config.scm.in)? I tried to add something like

(define-public %current-directory

`(,(getcwd))) 

to my config.scm.in but it does not work.

Best regards, 

Tatiana Sholokhova

Excellent.

The Cuirass repository is available at
http://git.savannah.gnu.org/cgit/guix/guix-cuirass.git

I have added your account to the group, so you should have write access
to the repository now.  Please push your commits to a new branch on that
repository.  Please also read the section “Coding Style” in the Guix
manual.

You are welcome to rewrite your own published commits in your own
branch, but not in other branches.  When you want us to comment on your
work, please let us know the range of commits that you would like us to
review.  Ideally, we would be able to merge your work into the “master”
branch regularly.

Yes, this sounds like a good idea.  It is not absolutely necessary, but
it would be nice if basic features of the interface would still be
usable even when _javascript_ is disabled.

It is fine to use Bootstrap.  Please include the unminified Bootstrap
CSS and JS files to the repository.  It is easy to minify them later,
but it is virtually impossible to turn minified code into something
readable.

Yes, this can be done by the Cuirass web server in Scheme.

In the web interface for RCAS I’m dispatching to “render-static-asset”
in the controller:

    https://github.com/BIMSBbioinfo/rcas-web/blob/master/rcas/web/controller.scm

“render-static-asset” is defined here:

    https://github.com/BIMSBbioinfo/rcas-web/blob/master/rcas/web/render.scm#L65

As you can see, this module defines a bunch of mime types and includes
the appropriate type in the headers along with the contents of the file
it serves.

Hope this helps!
