I've been using Wordpress for awhile, it's installed on my own server, and one of the features I most love about it is how every time there is a new version it alerts you within the app's web-based admin and with one click I can upgrade the app. I don't have to get anywhere near a console. Personally I wouldn't mind updating manually, b...
Had some old code that on some condition would modify params. I believe it was working before (not 100%). We are now getting params set to nil whether or not the condition is met. The culprit is within the condition, I perform a params = tmp.dup. Even when the condition is false, this is causing an error in the update action. I was abl...
Note: I'm using Rails 2.3.8, not 3. I have a Photo model with a default_scope: default_scope :conditions => ["published = ?", true], :order => :position Calling photo_album.photos returns all published photos ordered by position as it should. However, when looping through these photo albums in an admin panel to display the number of ...
This is a method that used to be in the controller and I think it makes more sense to make it a method to the Contact model: def colleagues company = Company.find(self.company_id) contacts = company.contacts.collect(&:full_name) contacts.each do |contact| colleagues = contacts.reject{ |c| c==contact } end ...

I recently migrated my application across servers and set up my directories a little. I ran into a problem where I had hard coded some paths, in particular, where I store all my attachments. I moved my attachment directory in app_path/../attachments/* Is there a variable that gets me my app_path, rails root directory, or whatever the...
I can't get send_file(Model.attachment.path) to work. It doesn't fail, instead, it sends a 0 byte size file to the client, the file names are correct though. This problem started happening after I did a big migration from Rails 2.3.8 to 3. There were a lot of other things that took place in this migration and I will try my best to deta...
I am trying to use link_to_remote with :with parameter so I can pass my parameters but I am using jrails and it seems it doesn't work. I use it another spot with jrails and prototype and it worked fine. Here is my code in jrails where I don't use prototype: <%= link_to_remote render(:partial => "back_button_text"), {:url => { :contro...
I use Authlogic to log the user in. Inside a Rails Metal I want to check if the user is logged in or not. Just that, I don't care who the user is. I want to avoid touching the database so I should not do UserSession.find. My main doubts: Will making use of env['rack.session'] solve that? Where is that stored? Is that secure? I'm current...
Is there a way to make this one liner better looking? @var = params[:key1][:key2] unless params.blank? || params[:key1].blank? ...
Hi, In rails 2.x I could pass on a --git option to ./script/generate to add files to git automatically after creation. However I have been unable to find such an option (or configuration) in Rails 3.0. Has this been removed or am I missing something? I tried researching this for a while but I am unable to find any reference. Thanks, P...
Hi, i need to insert nbsp symbol in some places of the HTML, that comes from DB and will be displayed on the page. I do following: doc = Nokogiri::HTML( self.content ) doc.css("p").each do |p| p.content.gsub! pattern, " " end This resulting text contains nbsp, displayed as a plain text, but not a special symbol.

Hi folks, I am trying to understand the Active Record Callbacks, but they do not work, like I want to. e.g. Model Checklist<ActiveRecord... attr_accessible :item1, :item2, :done # they are all boolean before_save :check_done private def check_done if item1 && item2 write_attribute :done, true else write_attribute :done, ...
Hi Everyone, I am working on a basic app that has a public facing form (for enquiries) that anyone can fill in and submit. The results are then stored for the company to do what they want with. I have made sure that if the user is not logged in they can only access the create page, but once they submit the form, as expected, they are t...
So, I have this block of code, and yes it looks ugly. Is there a better a data structure I can use to compare row.add,row.modify,row.delete and row.query with "Y" and call the get_role function? Note this block of code runs in a loop, hence the 'row'. if row.add == "y" role_ids << get_role("c") end if row.modify == ...
I starting to investigate whether Ruby-on-Rails will help solve my problem in some way? In short, I have a legacy Linux system and application which is reading and writing a collection of images. This application also uses a sqlite database to help refer to correct image files when required. What I'd like to do is have an iPhone and/or...
How do I come to know whether a create or any other action has been called from inside a model. Basically I am doing database logging and want to track whether a create or other actions are being performed. For doing the logging part I am using the concept of ActiveRecord::Observer. But there I am not able to find out whether the user i...
