similar to: More elegant solution for "missing" has-many through ids?

I''d like to delete some records before saving them. I ran this experiment: before_save :prune_lab_datas def prune_lab_datas lab_datas.each do |lab_data| lab_data.destroy end raise lab_datas.to_yaml end But nothing seems to be deleted in the hash: --- - &id001 !ruby/object:LabData attributes: created_at: 2010-03-21 22:16:06 unit_id: "3"

Hi Gurus, I''m trying to tackle a drop down list. I have category and item dbs, and they''re wired up with category has_many :items and item belongs_to :category, and an item has a category_id. I have this code in my new/edit.html.erb for item: <%= f.collection_select :category_id, Category.find_main, :id, :header, {}, :multiple => false %> And a pretty drop down list

I''m a fairly visual person, and I have a piece of paper with many boxes and arrows with labels like "has many" and "belongs to" for my database models. It''s messy, but it works. What I keep looking for--weeks, actually, I''m certain it''s out there, but I haven''t hit on the right set of Google query terms :)--is something that will

I'm admin on a samba PDC with 150 users, and as normal users they are quit "stupid". This means that they ofte deletes something that shouldnt have been deleted. And I find it anoying to restore their files from tapebackup. So would it be possible to get samba to "move" files instead of deleting them? This way I could allocate a disk to store deleted files for a periode of

I''m doing a series of ruby on rails tutorials and it got to a part where i need to edit the following files that should be automatically inside the public folder: dispatch.cgi,dispatch.fcgi,dispatch.rb but I have none of these inside my public folder. Is there a reason for this? And how can i change it so they are back The only files in my public folder at present are 404.html 500.html

Version is cvs checkout today at approx 0900 CET. Running on a debian/unstable box with dist-upgrade as of 0830 CET today, and with no windows installed. Problem can easily be reproduced, and deadloc happens everytime I do this. Open database, everything is fine, open document.. wait a few seconds and wine hangs. output from wine: -- err:win32:_EnterSysLevel (0x4075062c, level 2): Holding

Hi. Im am considering porting an c++ application to Ruby, and me company would also like to have an web-version of this particular application. If say there is an XML validator in the app. Then can Ruby and RoR share this in an easy way, so i wouldnt have to maintain 2 branches of the same XML validator. Best Regards.

My system is a debian/unstable box. I'm running daily cvs snapshots of wine and Lotus Notes R5.07. The problem is that it seems like wine isn't getting the redraw messages from the application or wine isn't sending the redraw messages to the application. So I get large areas of the program blank/black/see through to old gfx. It especially occurs with frames/framsets in notes. For

hi, im using acts_as_tree and im not sure on how to group find-result. x = find.almost_all <p> <% for y in @x.ancestors.reverse %> <%= link_to h(y.title), page %> &gt; <% end %> </p> gives me a nice "breadcrum". but how is it possible to group the list lets say by the 1level or second level? thx -- You received this message because you are

Hello! I've tried to set up dovecot in conjuction with vpopmail, and running it under djb's tcpserver instead of (x)inetd. Btw - there was no reference to setting dovecot up using (x)inetd either in the manuals/faqs i read, though I didn't search all that hard. Anyway, back to my Q: vpopmail uses vchkpw as an authentication mechanism, and with tcpserver I can do relaycontrol (based

I wish to save a scatter plot comprising approx. 2 million points in order to include it in a LaTeX document. Using 'pdf(...)' produces a file of size about 20 MB, which is useless. Using 'cairo_pdf(...)' produces a smaller file, around 3 MB. This is still too large. Not only that the document will be too large, but also PDF viewers choke on this. Moreover, Cairo has problems

Hi, fp is a data frame like this ,----[ fp ] | Frequenz AmpNorm | 1 3322 0.0379490639 | 2 3061 0.0476033058 | 3 2833 0.0592954124 | 4 2242 0.1275510204 `---- i want to find the "Frequenz" where "AmpNorm" is max. I use this line as workaround: PeakFreqHz = subset(fp, AmpNorm == max(AmpNorm))$Frequenz[1] Is there something nicer? And is there an

Hi. Im quite new to this Rails thing, but it seems like a good product so why not try it out whit a little prototype i need to build. What i want is to load any given XML file, and display it with some formatting. I have some XSD shemes to validate the XML files against, but its not vital rigth now. But how should i approach this task? At first it would proberly be a good idea to load the

What is the rationale behind having both the delta and sd parameters for the power.t.test function? For the relevant noncentrality parameter, we only need the ratio delta/sd. If my effect size is given as Cohen's d, then I only got that ratio and not sd. As far as I see, in such a case, I can specify delta=d and leave sd at its default value 1. Is this correct or am I missing something?

Hi. I have for a while been trying to get my samba 2.2.1a PDC to be a NIS master and still maintain the password sync feature, without any luck. Now I made something that seems to work - but I would like to get your input to see if what I do is ok or it is something I should'nt do. 1: Samba uses passwd to sync the password (not yppasswd) 2: cron runs make in /var/yp every 15 minutes to
