问题 I want to be able to update my user information without having to have the user set a password each time they edit any other attribute. My current validations are: validates :password, presence: true, length: { minimum: 8 } validates :password_confirm, presence: true how can I make this conditional? It would be clever to only require these validations if the password and password_confirm attribues were in the params. I could use some idea about how to achieve this. Thanks. 回答1: I think this

问题 I have used radio buttons in my app countless times, and never have experienced this issue, so I am assuming I am oblivious to a very dumb mistake. The form submits all the other model's attributes just fine, but for some reason, :referral_type just does not show up in params in the server output, and it of course is not saving to the db. = form_for(@writer, :html => { :class => "user_new", :id => "user_new" }) do |f| - unless @writer.approved? .field.divider %label How did you hear about us?

问题 I'm trying to store an array (:vehicles) in my database. This array consists of 3 possible vehicles that the user selects with checkboxes. <% @vehicles.each_with_index do |vehicle,index| %> <label> <div > <%= check_box_tag "vehicles[]", index ,class: "available" ,style: "display:none" %> <%= vehicle %> </div> </label> <%end %> The ':vehicles' attribute type is 'text' and I used this code to make it an array: serialize :vehicles, Array If I send the params it gets these values in an array.

问题 In my last Rails project I had to overwrite default_url_options in application_controller.rb to always pass a param through every request, like this: def default_url_options { :my_default_param => my_param_value } end Now every url helper attaches a my_default_param at the end of every generated url. For instance user_url(@current_user) generates a url like: http://www.example.com/users/1?&my_default_param=my_param_value But sometimes I need to generate the url without my_default_param . Is

问题 In a specific controller I have the below list of params: Parameters: {"user"=>"{\"id\":32,\"email\":\"test@test.com\",\"created_at\":\"2014-04-10T13:13:40.000Z\",\"updated_at\":\"2014-04-11T18:10:15.000Z\"}"} How I can get the value of email for example? 回答1: You value looks like json. So try this user_params = ActiveSupport::JSON.decode(params[:user]) user_params[:email] or require 'json' user_params = JSON.parse(params[:user]) user_params[:email] 回答2: You can do params[:user][:email] #=>

问题 If I have a method that has a params parameter, can it be passed by reference and updated every time a yield is called.
