  • Saving an ActiveRecord non-transactionally.

    - by theFunkyEngineer
    My application accepts file uploads, with some metadata being stored in the DB, and the file itself on the file system. I am trying to make the metadata visible in the application before the file upload and post-processing are finished, but because saves are transactional, I have had no success. I have tried the callbacks and calling create_or_update() instead of save(), all to no avail. Is there a way to do this without re-writing the guts of ActiveRecord::Base? I've even attempted naming the method make() instead of save(), but perplexingly that had no effect. The code below "works" fine, but the database is not modified until everything else is finished. def save(upload) uploadFile = upload['datafile'] originalName = uploadFile.original_filename self.fileType = File.extname(originalName) create_or_update() # write the file File.open(self.filePath, "wb") { |f| f.write(uploadFile.read) } begin musicFile = TagLib::File.new(self.filePath()) self.id3Title = musicFile.title self.id3Artist = musicFile.artist self.id3Length = musicFile.length rescue TagLib::BadFile => exc logger.error("Failed to id track: \n #{exc}") end if(self.fileType == '.mp3') convertToOGG(); end create_or_update() end Any ideas would be quite welcome, thanks.

  • Rails - Create if record doesn't exist or else update.....Whats Best way to do this?

    - by ChrisWesAllen
    Hi, I have a create statement for some models but its creating a record within a join table regardless if the record exist. Here is what my code looks like. @user = User.find(current_user) @event = Event.find(params[:id]) for interest in @event.interests @user.choices.create(:interest => interest, :score => 4) end The problem is it creates records no matter what. I would like it to create a record if it doesnt exist, if a record does exist I would just to it to take the attribute of the found record and add or subtract 1. So, I've been looking around and I see something called find_or_create_by. My question is what happens if it finds? Preferably if it finds,I would like to take the current :score attribute and +1. SO is it possible to find or create by id? I'm not sure what attribute I would find by since the model I'm looking at is a join model which only had id foreign keys and the score attribute. I tried @user.choices.find_or_create_by_user(:user => @user.id, :interest => interest, :score => 4) but got "undefined method `find_by_user'".....ANy ideas or help?

  • Missing Required Gems - javan-whenever and cron job in rails

    - by Matenia Rossides
    Hi, I have finally managed to get javan-whenever gem working on my site5 server, and updating the crontab is quite easy, however whenever a cron job is run with the code that is generated, i get a "missing required gems" error where it lists about 8/10 of my gems. Has anyone else had this problem? If so, what would the solution be. The funny thing is that when it outputs where my gems are, this is all correct, and the gems are loading fine from within my application. Cheers, Matenia

  • show array size with will_paginate

    - by chief
    @users = User.paginate( :page => params[:page], :per_page => 2, I would like to return the total number of results. @users.size simply gives me the number of results on a page. If page 1 has 2 users @users.size = 2, going to page 2 with say 1 user @users.size = 1. How can I show the size of all the users?

  • How to update attributes without validation

    - by Brian Roisentul
    I've got a model with its validations, and I found out that I can't update an attribute without validating the object before. I already tried to add on => :create syntax at the end of each validation line, but I got the same results. My announcement model have the following validations: validates_presence_of :title validates_presence_of :description validates_presence_of :announcement_type_id validate :validates_publication_date validate :validates_start_date validate :validates_start_end_dates validate :validates_category validate :validates_province validates_length_of :title, :in => 6..255, :on => :save validates_length_of :subtitle, :in => 0..255, :on => :save validates_length_of :subtitle, :in => 0..255, :on => :save validates_length_of :place, :in => 0..50, :on => :save validates_numericality_of :vacants, :greater_than_or_equal_to => 0, :only_integer => true validates_numericality_of :price, :greater_than_or_equal_to => 0, :only_integer => true My rake task does the following: task :announcements_expiration => :environment do announcements = Announcement.expired announcements.each do |a| #Gets the user that owns the announcement user = User.find(a.user_id) puts a.title + '...' a.state = 'deactivated' if a.update_attributes(:state => a.state) puts 'state changed to deactivated' else a.errors.each do |e| puts e end end end This throws all the validation exceptions for that model, in the output. Does anybody how to update an attribute without validating the model?

  • how to save related models with non-null foreign key

    - by Fortress
    I have a model called user which has_one email. I put the foreign key (NOT NULL) inside users table. Now I'm trying to save it in the following way: @email = Email.new(params[:email]) @email.user = User.new(params[:user]) @email.save This raises a db exception, because the foreign key constraint is not met (NULL is inserted into email_id). How can I elegantly solve this or is my data modeling wrong?

  • Rails: Problem with routes and special Action.

    - by Newbie
    Hello! Sorry for this question but I can't find my error! In my Project I have my model called "team". A User can create a "team" or a "contest". The difference between this both is, that contest requires more data than a normal team. So I created the columns in my team table. Well... I also created a new view called create_contest.html.erb : <h1>New team content</h1> <% form_for @team, :url => { :action => 'create_content' } do |f| %> <%= f.error_messages %> <p> <%= f.label :name %><br /> <%= f.text_field :name %> </p> <p> <%= f.label :description %><br /> <%= f.text_area :description %> </p> <p> <%= f.label :url %><br /> <%= f.text_fiels :url %> </p> <p> <%= f.label :contact_name %><br /> <%= f.text_fiels :contact_name %> </p> <p> <%= f.submit 'Create' %> </p> <% end %> In my teams_controller, I created following functions: def new_contest end def create_contest if @can_create @team = Team.new(params[:team]) @team.user_id = current_user.id respond_to do |format| if @team.save format.html { redirect_to(@team, :notice => 'Contest was successfully created.') } format.xml { render :xml => @team, :status => :created, :location => @team } else format.html { render :action => "new" } format.xml { render :xml => @team.errors, :status => :unprocessable_entity } end end else redirect_back_or_default('/') end end Now, I want on my teams/new.html.erb a link to "new_contest.html.erb". So I did: <%= link_to 'click here for new contest!', new_contest_team_path %> When I go to the /teams/new.html.erb page, I get following error: undefined local variable or method `new_contest_team_path' for #<ActionView::Base:0x16fc4f7> So I changed in my routes.rb, map.resources :teams to map.resources :teams, :member=>{:new_contest => :get} Now I get following error: new_contest_team_url failed to generate from {:controller=>"teams", :action=>"new_contest"} - you may have ambiguous routes, or you may need to supply additional parameters for this route. content_url has the following required parameters: ["teams", :id, "new_contest"] - are they all satisfied? I don't think adding :member => {...} is the right way doing this. So, can you tell me what to do? I want to have an URL like /teams/new-contest or something. My next question: what to do (after fixing the first problem), to validate presentence of all fields for new_contest.html.erb? In my normal new.html.erb, a user does not need all the data. But in new_contest.html.erb he does. Is there a way to make a validates_presence_of only for one action (in this case new_contest)? UPDATE: Now, I removed my :member part from my routes.rb and wrote: map.new_contest '/teams/contest/new', :controller => 'teams', :action => 'new_contest' Now, clicking on my link, it redirects me to /teams/contest/new - like I wanted - but I get another error called: Called id for nil, which would mistakenly be 4 -- if you really wanted the id of nil, use object_id I think this error is cause of @team at <% form_for @team, :url => { :action => 'create_content_team' } do |f| %> What to do for solving this error?

  • DB fields not showing up in association custom queries?

    - by Kevin
    I have a notification list that the user can select different show options for different kinds of notifications along with how many results are returned. I'm keeping them in the user model because I want the custom sort to stay with the user between sessions. Here is the association in my user model: has_many :notifications, :class_name => "Notification", :foreign_key => "user_id", :conditions => ["won = ? and lost = ? and paid = ?", self.prefs_won, self.prefs_lost, self.prefs_paid], :limit => self.prefs_results.to_s But when I use the above code, Rails throws me an "unknown method" error for self.prefs_won. It is definitely a field in my database and set as a boolean value, but Rails can't find it... what's the problem?

  • STI and accepts_nested_attributes_for in rails

    - by ryanshackintosh
    I have models as follows: class Entity < ActiveRecord::Base has_many :addresses accepts_nested_attributes_for :addresses, :reject_if => lambda { |a| a[:label].blank?} , :allow_destroy => true end class Client < Entity before_save :set_type private def set_type self.type = "Client" end end class Address < ActiveRecord::Base belongs_to :entity end I have recently implemented accepts_nested_attributes_for on the /clients/new form, as follows: <% form_for(@client, :html => {:class => 'form'}) do |f| -%> <%= f.label :name %> <%= f.text_field :name -%> <%= f.label :phone %> <%= f.text_field :phone %> <% f.fields_for :addresses do |a| %> <%= a.label :street %> <%= a.text_field :street%> <%= a.label :city %> <%= a.text_field :city %> <% end %> <% end %> And my controller as follows: class ClientsController < ApplicationController before_filter :load_client , :except => [:index, :new, :create, :render_clients] def new @client = Client.new @client.addresses.build end def create @client = Client.new(params[:client]) if @client.save flash[:notice] = 'Client has been successfully added' redirect_to @client else render :action => 'new' end end The issue is that when the record is saved it gives an error stating: "Entity can't be blank" I assume it is something to do with the fact that a 'Client' and not an 'Entity' is being added. Can anyone point me in the right direction?

  • Syntax errors on Heroku, but not on local server (postgresql related?)

    - by Phil_Ken_Sebben
    I'm trying to deploy my first app on Heroku (rails 3). It works fine on my local server, but when I pushed it to Heroku and ran it, it crashes, giving a number of syntax errors. These are related to a collection of scopes I use like the one below: scope :scored, lambda { |score = nil| score.nil? ? {} : where('products.votes_count >= ?', score) } it produces errors of this form: "syntax error, unexpected '=', expecting '|' " "syntax error, unexpected '}', expecting kEND" Why is this syntax making Heroku choke and how can I correct it? Thanks! EDIT: I was using sqlite on my local machine and Heroku does not support that. Trying to make sure the db is properly configured for PG. I believe I have done that by specifying in the gemfile that sqlite only be used in development. Yet I still get these syntax errors, that interrupt even the db:migrate. EDIT: So now it seems more likely that my scope syntax doesn't work in postgreSQL. Does anyone know how to convert this properly?

  • How to test that invalid arguments raise an ArgumentError exception using RSpec?

    - by John Topley
    I'm writing a RubyGem that can raise an ArgumentError if the arguments supplied to its single method are invalid. How can I write a test for this using RSpec? The example below shows the sort of implementation I have in mind. The bar method expects a single boolean argument (:baz), the type of which is checked to make sure that it actually is a boolean: module Foo def self.bar(options = {}) baz = options.fetch(:baz, true) validate_arguments(baz) end def self.validate_arguments(baz) raise(ArgumentError, ":baz must be a boolean") unless valid_baz?(baz) end def self.valid_baz?(baz) baz.is_a?(TrueClass) || baz.is_a?(FalseClass) end end
