update-attributes

问题 I am creating a recurring event app where certain users (streamers) can schedule recurring weekly events (streams) and other users (viewers) can follow them. The result is a personalized weekly calendar detailing when all followed streamers' events begin and end. However, because viewers can follow an infinite number of streamers and therefore the resulting calendar would look like a hot mess. So I added a boolean attribute to the relationships table that indicates whether the relationship

问题 I've been working through the Ruby on Rails Tutorial by Michael Hartl. Currently, in order to edit any of the User attributes, the user must confirm their password. Is there any way to update the user attributes without having to do this? My form looks like this: <%= form_for @user do |f| %> <div class="field"> <%= f.label :course1 %><br /> <%= f.text_field :course1 %> </div> <div class="actions"> <%= f.submit "Update" %> </div> <% end %>" and my update definition in users_controller.rb looks

问题 My problem is I've run into limitations of accepts_nested_attributes_for, so I need to figure out how to replicate that functionality on my own in order to have more flexibility. (See below for exactly what's hanging me up.) So my question is: What should my form, controller and models look like if I want to mimmic and augment accepts_nested_attributes_for? The real trick is I need to be able to update both existing AND new models with existing associations/attributes. I'm building an app

问题 I cant figure out how to update/rename a file uploaded/managed with Carrierwave-mongoid in rails 3.2.6. I want to rename the file in the db as well as on the filesystem. Something like this maybe... def rename( id , new_name ) f = UploadedFile.find(id) if f.update_attributes({ f.file.original_filename: new_name }) # this is WRONG, what is right??? new_path = File.join( File.dirname( f.file.current_path ) , new_name )) FileUtils.mv( f.file.current_path , new_path ) end return f end Let me add

问题 I'm having a problem getting update_attributes to update nested models in my form. I don't have any errors but the nested attributes aren't saving. Here's the relevant code: Users model: class User < ActiveRecord::Base has_many :orders has_many :achievements accepts_nested_attributes_for :achievements Achievements model: class Achievement < ActiveRecord::Base belongs_to :user Edit User form: <%= form_for @user, :html => { :multipart => true } do |f| %> ... <%= f.fields_for :achievements do |

问题 I have a status report a user can send by email and I want to update a column :sent_mail to true, after the deliver action is completed. def send_status date = Date.today reports = current_user.reports.for_date(date) ReportMailer.status_email(current_user, reports, date).deliver reports.update_all(sent_mail: true) end and the table class AddSentMailToReports < ActiveRecord::Migration def change add_column :reports, :sent_mail, :boolean, default: false end end However, in console, sent_mail is

问题 Object.update_attribute(:only_one_field, "Some Value") Object.update_attributes(:field1 => "value", :field2 => "value2", :field3 => "value3") Both of these will update an object without having to explicitly tell AR to update. Rails API says: for update_attribute Updates a single attribute and saves the record without going through the normal validation procedure. This is especially useful for boolean flags on existing records. The regular update_attribute method in Base is replaced with this

问题 The correct custom params are being displayed in my debug function after the form is submitted but the default params are displayed when I enter console. Controller def update current_user.update_attributes(params[:user]) flash[:success] = "Your settings have been saved!" render new_status_update_path end Model attr_accessible :deficit_pct, :target_bf_pct, :activity_factor Notes: The closest question I could find to this on SO is a question that changes the attributes of an object that exists

问题 So in my view I'm using a calendar to select a day and drop downs to select time. Therefore I'm using a before_validation method to put it together: proposed_time.rb before_validation :construct_starting_at def construct_starting_at d = Time.parse(date) puts "************** construct_starting_at BEGIN *****************" puts "DATE: #{d}" puts "Time: #{time}" puts "Timezone: #{timezone}" puts "construct_starting_at :: #{d.year}-#{d.month}-#{d.day} #{time.hour}:#{time.min}:00 #{timezone}" if
