Hi - I have 3 fileds a user can fill out. They can fill out 2 of them or just one of them, for example. fill out these 2 fields: Field1 and Field2 Or fill out this field: Field3 In my model how do I use validates_presence_of for Field1 and Field2 or just Field3. I want to do something like this: validates_presence_of Field1, Field2 OR validates_presence_of Field3 So the user can fill out

Hi, How can I use a substring match as a condition in a subset command? Sth like this: subset(input, field1=="blah1" & field2=="blah2") # but now with substring match in field2 subset(input, field1=="blah1" & field3 *substringmatch* "blah3") I've tried with gsub, but it won't work: subset(input, field1=="blah1" &

I want to add virtual fields in a model. table: field1 field2 I want to add field3 which is field1*2 + field2 I know tihs can be achieved in View, but I want it in model. Then I will pass this model to PagerRenderer to paginate. How to achieve this? thanks -- Posted via http://www.ruby-forum.com/.

Say I have a csv file, each row contains several fields, one of them are whether the row is success. In history data, I have all the fields including the result of whether it is success. In future data, I only have fields without the result. For example: history data: Field1 Field2 Field3 Field4 ResultField 1231 CA TRUE 443 TRUE 23231 NC TRUE 123 FALSE

I''m trying to get a Rico LiveGrid working, and I am a bit stuck on how to accomplish this. I have a page that successfully queries a controller and updates a <div> containing a table. I have two versions of the action; one uses the render_partial to return a rendered version of that table, and the other returns an XML-RPC document, and this is where I hit a snag. The Rico LiveGrid

I''m new to rspec and looking for way to test a validation I added to a model. The test checks to see that if field1 has a value then field2 must be nil and vice versa. ------------------------------- When I did the rspec_scaffold it generated one test which worked before :each do @valid_attributes = { :field1 = "value for field1" :field2 = "value for

I believe that I may have found a bug in R. The top code sample gives an error as shown. However, by simply switching which field is initialized first as in the bottom code sample, it works as expected. This gives an error: a <- NULL a[["field1"]] <- 1 a[["field2"]] <- matrix(c(2,1), 1) Error in a[["field2"]] <- matrix(c(2, 1), 1) : more elements

Hi, The following [simplified] query works well, however a variation which includes parenthesis seems to fail, in that it returns hits which should be excluded by the NOT term. This is surprising because in this simple case, the parenthesis shouldn''t change the Boolean evaluation ... any pointers? Working Query: field1:value1 AND NOT field2:value2 Failing Query: field1:value1 AND

hello everyone, i'm new to R, so i hope you dont mind a fairly basic R question. we're using R to manipulate the results of SQL queries and create an HTML output. I'm starting with a table that looks essentially like this: Name Field1 Field2 John value1 value2 Jane value3 value4 My table is stored as a dataframe. I'd like to efficiently produce an

Hi all, My current project brought forth the snippet below, which modifies in each row of a data frame a certain field depending on another field in the same row. Dealing with data of some 30000 entries this works, but is horribly slow. Can anyone show this newbie how to do this properly (faster ;0)? for (i in 1:nrow(dataframe)){ if

Hello everyone, I've been advised to use merge to extract information from two data.frames with a number of common columns, but I cannot get a grasp on how it sorts the result. With sort=FALSE, I would expect it to give the result back sorted exactly as the input was but it seems it is not always the case, especially when there are repeats in the input. For example: > a =

Hi, I am investigating a poor code generation on x86-64 involving a 64-bits structure with two 32-bits fields (in the attached examples float, but similar behavior is exposed with i32, and we can probably generalize that to smaller types too). The root cause of the problem is in SROA, although I am not sure we should fix something there. That is why I need your advices. ** Problem ** 64-bits

everyone, Just out of curiosity, I did a dtrace -n ''syscall:::entry { @num[execname, probefunc] = count(); }'' and looked at the entries produced by ''rm''. I see everything that rm did, *except* the unlinkat - which is unfortunate because I want to trace which processes have deleted which files. So - does dtrace contain unlinkat as a probe for a system call?

Hello all, I have a syntax question. How does one refer to a field brought in via a has_one/belongs_to relationship in a form helper? Basically, I have two models: class Resource < ActiveRecord::Base has_one :other_thing end class OtherThing < ActiveRecord::Base belongs_to :resource end It has the normal id-resource_id foreign key relationship. OtherThing has two fields, plus the
