Please can someone show me the correct syntax for a hidden field in forms, this is my code <%= start_form_tag :action => ''create'' %> <div class="form1"> <table width="auto" boader="8" cellspacing="5" cellpadding="5"> <% hidden_field ''line_item'', ''client_id'', :value

I use recordPlot() to save plots to disk that I render later to a variety of formats. This works fine for base R plots and ggplot2 plots, and also used to work for lattice plots. However somewhere in version 2.14 things stopped working for lattice plots. Here is an example: library(lattice); histogram(rnorm(100)); x <- recordPlot(); saveRDS(x, "myplot.rds"); y <-

Hi, something wrong with ActiveRecord or YAML? They don''t put Strings into Quotes when it serializes. This gave me trouble when I serialized a String with a double colon (eg. ''key: value''). After AR unserialized the Value it became a Hash since a String ''key: value'' becomes attribute[:key] => value... :( Sincerely Florian

The Database object itself effectively does (it works in a snapshot of the state of the database when you open it, or last called reopen() which

I am suffering for slow searching performance on Xapian. I am using Xapian for indexing about 150,000,000 documents. It was implemented in C++; The performance of searching was not that fast. e.g. Searching a query, which includes about 20 terms, needs 2 secs avg. For searching, I followed such steps: 1. construct a QueryParser for certain string 2. parse the query to get a Xapian::Query

Hello, I came across the file *omega.cc* which is in directory* xapain-application/omega/* In this file , atoi is used in *Percentage Relevance cutoff *(293 line no) as Percentage lies between 0-100 their is no need to modify atoi . But do we need to check for error's ? Second Implementation is in *collapsing* (301) in which we collapse set of document under a key,range of this key has not

Hi, While debugging a network server I'm developing I noticed something unusual - call to unserialize() resulted in an error about loading a namespace. I was a bit taken back by this - why should unserializing an object cause a namespace lookup? Are there any other side-effects of unserialize() that I should be cautious about? I've been digging through the R_Unserialize() call, I

Hello, Are there any recipe to handle serialization / deserialization of external pointers. I'm thinking about something similar in spirit to the way we handle finalization of external pointers. Currently, if we create an external pointer, save the session, quit R, then load the session, we get a null pointer. One way I'm thinking of is to have an environment in the

Dear Members of Xapian Project, Sorry for troubling you this time. This is Miao LIU, a postgraduate student working on information retrieval system related areas. I have been using Xapian (https://xapian.org) for quite a few months as the database and the searching engine in my IR system. I am currently facing a tough problem that I'd like to put all my posting lists in memory of my

All, I have an attribute on one of my model objects that cannot be serialized because it contains a Proc. Is there a way for me to mark this attribute as "not to be serialized/unserialized" so that session marshaling/unmarshaling won''t fail? Thanks, Wes -- Posted via http://www.ruby-forum.com/.

Dear All, I've tried to build xapian-core 1.4.3 on MSYS2. It fails with attached error (undefined reference to `exp10'). I think it might be missing an explicit link to 'm'. I'm not able to fix this myself as I do not know autotools sufficiently well, but I hope you might be able to help. Cheers, Mario Emmenlauer -- BioDataAnalysis GmbH, Mario Emmenlauer Tel.

Hey guys ,Hi :) I am working on a hack which will allow the user to specify a weighing scheme (along with the parameters , if he does not not want to use the default values) to build the Eset (rather than using the hard coded TradWeight scheme with default k=1 ) as Olly had suggested that we can probably get better terms (a more relevant Eset) for query expansion if we use say something

I have undertaken a small project of writing a Vorbis decoder completely from the spec, with the goal of catching any errors, both typographically and algorithmically, in the spec. My "reference" decoder is also being written in an extremely methodical style, with practically no algorithmic optimization, such that it will be clear that every step has been copied exactly from the spec.

Hi all, I'm working with some huge array in R and I need to load several ones to apply some functions that requires to have all my arrays values for each cell... To make it possible, I would like to load only a part (for example 100 cells) of all my arrays, apply my function, delete all cells loaded, loaded following cells and so on. Is it possible to unserialize (or load) only a

For the last year we have been working hard in releasing an open source RESTful xapian server named Xapiand (https://github.com/Kronuz/Xapiand) that will offer clustering, replication and some other neat features (similar to what elasticsearch offers, but the final goals go beyond it); however, for our Xapiand server to work, we need to have a few changes in xapian-core that are **essential**.

I ran into an interesting error unserializing a file created with ascii=TRUE: R 3.5.1 (Windows or Linux): > unserialize(serialize(list(raw=as.raw(c(39,41))), NULL, version=2, ascii=TRUE)) Error in unserialize(serialize(list(raw = as.raw(c(39, 41))), NULL, version = 2, : ReadItem: unknown type 29, perhaps written by later version of R The same error happens when the

In other words, is it possible to avoid duplicates if new documents are inserted into the DB by another process in-between ->get_mset calls when reusing Xapian::Enquire objects? I do some expensive processing on each mset window, so I always limit the results to limit heap usage even if I'm planning on going through a big chunk of the DB: $mset = $enq->get_mset(0, 1000);

Hello, I've installed xapian-core 1.1.3 and xapian-bindings 1.1.4 from the tarballs announced by Olly the other day. With these versions, Enquire.get_mset() seems to consistently be raising xapian.DocNotFoundError. I've attached a small test case which reproduces this. The same test case works fine with 1.0.16 (not the latest 1.0.x, but it's what I had installed). Program output

Hello , I came across this function *HtmlParser::decode_entities(string &s)* in *xapian-application/omega/htmlparse.cc* which basically does is extract hex value if any or extract number.For extracting number atoi is used and value returned by it is stored in variable "val" , I think so replacing atoi with strtoul would be useful here as number can have larger value although the
