Hello!, I'm a RoR begginer, i need it to make a web interface for a bigger project that i'm developing in Ruby, but i don't know how to do the next:
I want to read a config file of my main program (a normal conf file), and be able to change some values. I take all the names and values pf my config file correctly via a ruby function, to change the values i think in a form which has a lot of inputs named like the vars i want to change, and send the new value. My post command it's correct for me, it contains the data i want (something like [name]value[name]value....) , but i don't know how i can access to the post variable to work with this data in Ruby ( i need to write a file [name] \n value .....) The code for my form its:
<% form_for :variable , :legend => "Personal info", :url => {:action => :save_post} do |$dataform| %> ....#Read my file ..... .... Name: <%=text_field_tag("#{var_name}", "#{value}", :size => 20)%> </p> <%= submit_tag "Change Config File", :class => "submit" %>
so, how can i access to the post variable?
Thanks!
