Ruby & Forms

Hi folks.

I’m trying to get my head around the implementation of Ruby forms. This is not Rails. I’m messing around in Sinatra and wanted to know how to receive submitted forms. I’ve looked at CGI and the params tag, but I’m unclear as to which one should be used.

Any urls and insight appreciated as I can’t find much out there. I’m confused between the two applications and I can’t seem to get params to work properly.

I’m building a small app using Sinatra. Here you can see the routes[1] and the views[2].

The “routes" are composed of two ‘paths’ the ‘get’ and the ‘post’ which ‘redirects’ depending on the situation.

The “views” are made using HAML which is a syntax-sugar for HTML like ERB, LESS, etc. I’m using CSS but you could use SASS instead if you like it...

NOTE: I’m using an MVC architecture (also called modular) Sinatra which you can see here: <a href="" title=""></a> based on riblits[3] skeleton.

If you need more details feel free to ask.

Hi there. Thanks for the reply.

Yeah the whole Sinatra thing I have working. It’s the submission of forms which got me. I’m reading about ARGV and params, and I was having trouble getting around the latter. I will be taking a look at your Ruby though. It seems you’re just searching through params, so that’s essentially what I was looking for. I need more testing.

Does Ruby qua Ruby even have a concept of HTML forms? It seems like
that'd be something that would exist only in the context of
Ruby+RailsOrSinatra. I think that for someone to answer your question,
they'd have to understand Sinatra's form handling, rather than Ruby's.

I do not understanding so much your question (my english is not good)
but, here I come:

For write form, I suggest you to use a template engine

slim is a good one ;)

for get forms values in sinatra, do a post methods and use the params

post '/' do

puts params['fieldname']


The params hash value always contain the request info...

For work with sinatra, ALL you need is in the README
