User Input from Ruby on Rails form -

im trying grab users input value (:url) in rails app. believe its

params[:user_input] 

but dont know how implement controller. place anywhere or in specific method?

method

 def index  @posts = post.all   embedly_api = embedly::api.new :key => '', :user_agent => 'mozilla/5.0 (compatible; mytestapp/1.0; my@email.com)'  url = params[:user_input]  @obj = embedly_api.extract :url => :user_input end 

how can user_input url can pass hash???

the params hash contains mapping of names of html form controls values provided user. access each 1 params[key_name].

in case, think want create local variable out of params[:url]. that's fine. use this.

def index   @posts = post.all   embedly_api = embedly::api.new :key => '', :user_agent => 'mozilla/5.0 (compatible; mytestapp/1.0; my@email.com)'   url = params[:url]   @obj = embedly_api.extract :url => url end 

however, local variable isn't necessary, make code more succinct removing local variable , doing instead:

@obj = embedly_api.extract :url => params[:url]
