similar to: migration with blobs

I have a mysql database that I am trying to use migrations on. The problem that I am having is that when I create a blob field in my migration file like so: t.column "data", :binary, :limit => 15.megabytes, :null => false rails changes it to this in the schema: t.column "data", :binary, :default => "", :null => false not only is this not what I wanted

Hi All, I am making a DAM (seems to be the hip thing to do these days). It is for the company that I work for. We have some really weird domain rules that have prevented me from just using a simple directory structure file permission system. I have come up with a solution but I wanted to run it by you gurus to ensure that I am not recompiling the wheel here. Basically the domain rule is: A user

Am i a total idiot to try and parse out a rails object for javascript in this way? <% for i in interface_items[0].attributes %> var <%= i[0] %> = "<%=h( i[1] )%>" <% end %> Am I missing something really obvious?

For a project that I am working on I need to have a family tree. This means that instead of having one parent each item has at most two. As far as I know acts_as_tree only allows one parent_id. Any suggestions on how to make a "acts_as_family_tree" ? Thanks, Mark -- -------------------------------------------------------------------- I am Mark Daggett and I approve this message.

i am making a category tree and i iterate over the category using my counter_cache however it would show a different number than what was actually being represetned in the tree. Here is an example cat.children = [cat2, cat3] puts cat.children.size 2 puts cat.children_count 2 cat4.parent_id = cat.id cat4.save puts cat.children.size

Is there such a thing that I could use to store sessions in the DB instead of in a cookie so that I can ensure users will be able to access their session data even across several load balancers? We use totally stateless machines here at work and I am worried about deploying a rails app in production that uses a volitile session stored on the machine. Any help is great! Happy Holidays, Mark --

Hello, I'm using an MGE Evolution 1500 with a Debian Sarge 2.4.27 smp server. NUT is using the mge-utalk driver. [ups1500] driver = mge-utalk port = /dev/ttyS0 Seens I did a test.battery.start, my UPS goes off (beep!) once per week (same day, same hour). I guess there should be a very easy explanation for this, unfortunatly, I haven't found it yet. I've tried to upgrade

Hi, I just upgraded to rails 1.1 this morning and i am getting a variety of errors from tests that were passing effortlessly on the previous edge release (i froze several weeks ago, so I not sure what version that was). Has anyone else experienced these types errors with the new rails: I have several errors that are grouped around create and destroy commands the errors are similar, first the

Hi I know there is no real requirements tag but I was unsure what to label this message, please don''t flame me :-). I am using the Javascript Integration Kit with Macromedia Flash to make a local connection to the rendered Rails view. I am then using Flash to render my page components (sort of like you do with Lazlo or Flex etc.) though Javascript acts as a proxy for me. Ideally I would

I am working on a very large Digital Asset Manager for a Los Angeles Based Fashion Company. The application is about 60% done. I need help finishing the project and advice on deployment scalability etc. I expect the project to need roughly a month''s help for an intermediate to expert Rails programmer. If you are a competent programmer and can work "ON-SITE" in the Southbay of

Ok, this statement may prove that i am designing my app incorrectly but I have several HABTM relationships in my application that I add to using the <<. However, this undermines my ability to validate uniqueness of my rows. As an example. a = Article.find(1) c = Comment.find(1) a.comments << c a.comments << c a.comments.size "2" Obviously, I''d like to

I am building a flash-based uploader for rails that allows multiple files to be selected from a user''s hard drive and then put into a queue for upload. This works great except that macromedia uploads everything as "application/octet-stream". This means that displaying the newly uploaded content inline is a pain because the browser asks to download it first. To get around this I

Hi converted two of my models to HABTM today but I am having a real hard time getting my unit tests to pass now. Specifically, when I destroy a record I get this error: ...many many lines of this above... (eval):4:in `destroy_without_habtm_shim_for_categories'' (eval):4:in `destroy_without_habtm_shim_for_categories'' (eval):4:in

I am trying to create a model that allows only unique assets to be added to a category. However, they could be added again to a different category. Finally, an asset can be shared across many categories. So my question is how do you check the uniqueness across a join table? This does not compile.... has_and_belongs_to_many :categories, :foreign_key => ''asset_id''

Hi I am trying to create a plug-in to fix the error in the rails core produced by the multiple delete on a HABTM relationship. I have confirmed that my plug-in is being included into the base during runtime however the code does not seem to be overridding the base class. module ActiveRecord module Associations module ClassMethods def has_and_belongs_to_many(association_id, options =

I''m struggling with activerecord and mysql blobs (uploading files)... blobs over 400K-ish cause the below exception... ActiveRecord::StatementInvalid in File#upload Mysql::Error: Lost connection to MySQL server during query: I''ve tried blob, mediumblob, and longblob... I''m using windows xp for development - and have not installed the mysql gem... simlar google

There is a problem with blobs in ActiveRecord when you''re using sqlite3: sql length limits. Sqlite3 limits the size of the sql queries to 1mb. Because AR puts everything into the sql text, you can''t insert a blob or a clob that is larger than about a meg. That sucks. So I''m trying to fix that, but there''s a problem (obviously, or I wouldn''t be
