Hi .. I am getting started with RoR and having fun :-) So, my problem is how to integrate the static and dynamic sides of the site I am making. I have a standard look-and-feel, the usual stuff, graphic header, left sidebar with menu, content in the centre. Some pages are static -- main page, contact, that kind of thing -- and some are dynamic, such as the admin pages. My problem is I

I''m trying to wrap my caffeine soaked brain around has_many :through following along at: http://rails.techno-weenie.net/tip/2005/12/23/teaching_your_blog_model_new_tricks_with_has_many_through I think my models are a little more complex than what fits this narrative. I have a directory of members, each member can belong to multiple categories. The category table references itself

Hi, We want to display on a small LCD screen next to our meeting rooms and optionally let people book the room from the panel. We looked at different providers and those solutions either works with Exchange or Lotus Notes... Since I already have code to fetch events from any CalDAV/WebDSV servers, I'm looking at building the system myself. So I'm wondering if any of you can recommend

Yesterday I got the beta version of ROR recipes book and the recipes are great. For those of you still thinking about it, I highly recommend the book. The only thing I wish is that if there were some more recipes (greedy me), especially AJAX related and installing an application within your current application. For instance, it will be great to see how one can implement the typo blog

Hello all, The itanium demangler in libcxxabi (and also, llvm/lib/Demangle) is really slow. This is largely because the textual representation of the symbol that is being demangled is held in a std::string, and manipulations done during parsing are done on that string. The demangler is always concatenating strings and inserting into the middle of strings, which is terrible. The fact that the

I created the well known group Domain Admins pointing to a local group, but I am not able to add users to the group -- it claims I can only add users to local or global groups... But I only see local, domain ,well-known, builtin. There are no global groups unless one would include all groups that are not local (i.e. domain, well-known, and builtin).... So why doesn't it want to let me add

I'm trying to fix a CentOS (5.5 x86_64) VM that we have where it become unstable due to swapping. But I did notice something: I have 10 httpd processes, and 5 of them are using 13 MB of resident memory, the other are using between 91 and 96 MB of RAM. I find it quite strange to see such differences in RAM usage. I ran a "lsof -P -p" on the processes, and I didn't see any major

Dear all, First of all, I thank you for the creation of the package. I write this message concerning the write.foreign() function from the foreign package and a bug that I discovered. When we want to save our dataset as a .sas file, the limit of variable names character is 8 by default. In SAS this limit is 32 character and an argument in the function, validvarname, can theorically switch the

Let''s say I have a class Job that has a series of possible locations that are stored as a sequence of foreign keys class Job acts_as_ferret { :locations => {} } def locations "1,25,23,15" # ?? end end Is that a good way to store the location ids? How would I search for Jobs in a certain location Job.find_by_contents(''locations(25)'') cheers

Hello, I currently have two tables. table_a ( id table_b_id other_attrs ) table b ( id name ) So table A holds an id from table B. During the listing of tuples in table A, it lists table A''s attributes. In place of the table B id, I check the id, and instead display the name corresponding to that id. Now I want to be able to sort the listing of tuples in table A by the

I have a one-to-many relation between my documents and statuses tables. I want to display only the documents whose states are not "Published". I haven''t figured out how to do this using the standard paginate method (maybe there''s a way using its :joins option). I''m also considering writing a custom paginator or using paginate_by_sql[1]. Does anyone have
