2 questions: redirect and form fields

Rails
1

Just three quick questions:

  1. when a user logs in, how do you redirect her to the last page they
    were on?
  2. what do most use for a form field that lists all the states in a
    certain country?
  3. when you create a form, the default size for the form is “size” =>
  1. Now I know I can change that number but what if I wanted to leave
    it out and control the width of my fields in css? also, how do I add a
    class="" to the form field (for css styling)?

Thanks,
Elle

  1. you can store the last request they made in the session, then upon
    successful login, use redirect_to to redirect them there
  2. I don’t so I will defer to others
  3. <%= text_field :obj, :method, :class => ‘foo’, :style =>
    ‘font-weight: bold;’-%> #etc, etc

You should check out the full documentation at

Thanks Bill.

I’ve tried a plugin called state_select and it worked good as long as
I wanted states from one country only.
The plugin can’t display states from both US and Canada.
So, I’ve added the following method to the application.rb:

def state_dropdown
states = [“Alabama”, “Alaska”, “Alberta”, “Arizona”, “Arkansas”,
“British Columbia”, “California”, “Colorado”, “Connecticut”,
“Delaware”, “Florida”, “Georgia”, “Hawaii”, “Idaho”, “Illinois”,
“Indiana”, “Iowa”, “Kansas”, “Kentucky”, “Louisiana”, “Maine”,
“Manitoba”, “Maryland”, “Massachusetts”, “Michigan”, “Minnesota”,
“Mississippi”, “Missouri”, “Montana”, “Nebraska”, “Nevada”, “New
Brunswick”, “New Hampshire”, “New Jersey”, “New Mexico”, “New York”,
“Newfoundland”, “North Carolina”, “North Dakota”, “Northwest
Territories”, “Nova Scotia”, “Nunavut”, “Ohio”, “Oklahoma”, “Ontario”,
“Oregon”, “Pennsylvania”, “Prince Edward Island”, “Puerto Rico”,
“Quebec”, “Rhode Island”, “Saskatchewan”, “South Carolina”, “South
Dakota”, “Tennessee”, “Texas”, “Utah”, “Vermont”, “Virginia”,
“Washington”, “Washington D.C.”, “West Virginia”, “Wisconsin”,
“Wyoming”, “Yukon”]
states.each do | s |
s
end
end

And I wanted to ask:

  1. Is this the right place to add this method?
  2. Would the above work?

Thanks,

Actually meant application_helper.rb
