is there a way using the file_column plugin to enforce a certain content type based on regex (i.ie, /^image/) and/or filesize (150k) ? thanks adam

how do i find the available methods available to my objects in file_column ? I noticed that i can do @post.image_relative_path for my @post object to retreive the relative path. What are all the other options available to my objects thru file_column ? thanks adam

in a multi-stage form, what is the proper way for handling the passing of the object thru each step ? If i have a database called events, and my controller looks like step = @params[:step] || 1 if step == 1 @event = Event.new @event = @session[:event] if @session[:event] elsif step == 2 @event = Event.new @event = @params[:event] elsif step == 3 @event = Event.new @event =

is it possible to store a field of type file_column in the session? Rails crashes on me every time i try to do something like the following: @session[:newpost] = @params[:post] however if i assign each field of @params[:post[ except for @params[:post]["image"] i have no problems.

Each of the data sets contains monthly observations on price indices for 7 countries. I use the fitted values from reg1 in the reg2 model. The interior loop executes without error as long as I explicitly specify the data set, i.e. data=dat70. However the code fails to execute if I specify the model in the form of the commented line, i. e reg1 <-dynlm(form1,data=Dnames[j]) I get the following

Dear List Members,I am trying to set up a large system of equations and I am trying to find a simple way to set up the list command under the package system fit. Here is the example from system fit and what I am trying to do: EQ1 <- Y1 ~ X1 + X2 + X4EQ2 <- Y2 ~ X2 + X3EQ3 <- Y3 ~ X2 + X3 + X4EQ4 <- Y4 ~ X1 + X3 + X4eqSystem <-list(form1 = EQ1, form2 = EQ2, form3 = EQ3, form4 = EQ4)

Hello, I've written a small function that's supposed to save me some time, and it's ending up killing it- the intention is to iteratively subset a dataset fram on framevec, fit a model (either lm or nls depending on type) and return the r2 or AIC from the model, respectively. Although as far as I can tell in my code the plots are dependent on the fit of the model to the data and the

What does everyone on this list think about enhancing scaffolding somehow so that a "has_many" relationship will automatically drop the <select> box into the view to reference the "belongs_to" part of the view? I think scaffolding is great but I am always adding the <select> boxes to reference the parent association. Do you think this would be useful? just a

I''m trying to use the file_column plug-in to attach a file to a newsletter posting. It works fine if I get the form right the first time, but if I get an error, such as not typing in a required field, and the form re-displays, my file selection box reverts to "no file selected." Here''s my relevant controller code: def new @newsletterpost = Newsletterpost.new

Hello, I'm testing a simple delphi application that have 3 forms. >From FORM1 (the main form) I press a button to show FORM2, then from FORM2 I press a button to show FORM3, when I close FORM3, FORM1 becomes focused instead of FORM2.

Does anybody have any issues with the AJAX code inside rails? Whenever i use any sites i have built, or even external sites (such as basecamphq) my internal security device blocks access to the Ajax piece with a 400 Bad Request ( i scoured the net for other ajax examples and no isses anywhere else). I think there is something in the AJAX code of rails that is not implemented correctly. Has

Hey, I have been progressively learning more and more rails each day (from both a current project, reading the agile book, and this list). Does anybody think it would be beneficial to have kind of like a rails "Best Practices" page that lists some of the better ways of handling certain functions of rails (that are common in most apps) that are both more elegant, and efficient. For

when retreiving a date from a DATETIME field in a database, is there a way to set the date to the value of the DB in the view? It seems to always default to the current date... if I have a field called birthdate in the users table and i do @user = User.find(@params[:id]) in my view i have a <%= date_select ''birthdate'',''user'' %> but dont know how to

Im using the file_column plugin to upload files from my application. The problem I am encountering is that I have a form with 2 file upload fields and when I submnit that form with files selected, I would get a message from the browser(Firefox) saying that a script on the page is taking a long time to execute and whether I want to cancel it or continue. Whichever option I choose, only 1 file(PDF)

Here is a function I wrote. It runs no problem, but generate empty pdf files. I can't find what is the problem. create.pdf<- function(x, dir) { dir.create(dir, showWarnings = FALSE) plist<- c("a", "b" , "c", "d") for(j in plist) { filedir<- paste(dir, "/", j, ".pdf",

I built out a simple CMS for websites that rely heavily on portfolios. This covers graphic and web designers in particular, but also other people with stuff to show off. It''s really easy to customize progressively, so that some people will only modify CSS, but others will dig deeper into Javascript behaviors and the Rails view code.

For those who cant access IRC, or just looking for a quick browser based alternative, i started an open jabber powered webchat for rails. Hopefully this will be a nice alternative for people to go to ask questions, get some help, offer some help, etc. I hope the community enjoys it, just trying to give a little back for all the hard work. It can be accessed here http://jabber.dufftech.com

I''m writing a ''Mailman'' model that catches emails sent to my application (kind of like backpack, I think). The trouble is that I''d like to save image attachments in the same was that file_column saves them--in fact, I''d really like to use a simple assignment like photo.image = attachment to save the image in its proper place. However,
