如何路由多个页面以“编辑”用户帐户信息（Rails）

Question

I currently have a Ruby on Rails application with a typical User model. I would like to allow users to edit their own account information, and change their email or password. However, I would like to have the corresponding forms for this on two different pages.

There is a users_controller.rb which already has a show , new , create , and edit path. The problem is that using the edit path to update the User database would require all forms to be on the same page, which is inconvenient for users who only wish to update their email or password, and not both. Essentially, I need that edit path to be available on multiple pages.

Any suggestions?

Answer 1

Split the form up into separate .html.erb files (like email.html.erb and password.html.erb ) and in your controller write something like:

def edit
  ...
  if params[:email]
    render 'email'
  end
  if params[:password]
    render 'password'
  end
end

Obviously the conditions can be whatever you want.

Answer 2

Not possible. Only one action per named route.

You could use one named route plus an extra parameter to tell the controller which form (or parts of a form) to render:

named route                                  path
edit_user_path(@user, :form => "info")       mysite.com/users/1/edit?form=info
edit_user_path(@user, :form => "acct")       mysite.com/users/1/edit?form=acct
edit_user_path(@user)                        mysite.com/users/1/edit

Then read this parameter and switch between templates depending on the value. No parameter will render the default view containing the full form:

def edit
  # ...
  case params[:form]
  when "info"
    render :template => "info_only"
  when "acct"
    render :template => "name_and_password"
  else
    render :action => :edit
  end
end

I assume this is just for UX and not for security. All of these separate forms will PUT to the same update action, meaning all attributes accessible in one form (eg. password) will be accessible in another form.
