similar to: file_field_tag : what was the original file name?

I am uploading a .csv file for importing into a database; however, this file does not need to be saved on the server. How do I get the file name of the original file? I know about the file_column plugin but I don''t need/want to save the uploaded file on the server, I just need to import it and delete it. Right now the file name get returned as some random temp file name... there has to be

Dear R helpers, I have a data.frame as given below - dat1 = data.frame(date = as.Date(c("3/30/12","3/29/12","3/28/12","3/27/12","3/26/12", "3/23/12","3/22/12","3/21/12","3/20/12", "3/30/12","3/29/12","3/28/12","3/27/12",

For some reason, I''ve posted this question to this forum 4 times now and it never appears in the daily consolidated email I get daily? I''ve written a routine allowing the client user to declare where their .csv import file resides and then send it to the server to import the many rows into an existing model table, and then throw it away. I''ve imported many graphic files

ROR newbie here... I''m trying to build a form to upload a CSV file, then parse and store the data. I have debugged this code up this point, but now when I browse to my csv file, and click Upload, I get this error: "Missing template uploads/process_file.html.erb in view path..." Here is my view (in /uploads/new.html.erb) <% form_tag ({:action =>

I''m using attachment_fu, and can make an attachment object (a Logo, which is basically an image file) fine using the tempfile that is returned from the file_field_tag on a form. However, i also need to make some from some files that are saved locally, in my public folder. I''m making a Tempfile object using the local file, but when i pass it to attachment_fu, it fails and

Hi, The documentation doesn''t make it clear why both file_field and file_field_tag are both useful. What is the reason for having two instead of just one of these? Thanks, Peter

Hi all, I''ve been using mechanize for a while and it rocks. Docs are pretty clear and so far I''ve been able to do it on my own. However, I''m stuck in a weird situation in a script to download my contact list from hotmail. I''ve used Firebug to check all urls, and tested it by hand while logged in via browser. Even in the script everything works well until the

It looks like an encoding problem. It works fine for me with R encoding set to UTF-8 Here is part of my sessionInfo() results [1] LC_CTYPE=en_CA.UTF-8 LC_NUMERIC=C [3] LC_TIME=en_CA.UTF-8 LC_COLLATE=en_CA.UTF-8 [5] LC_MONETARY=en_CA.UTF-8 LC_MESSAGES=en_CA.UTF-8 I would suggest issuing the command sessionInfo() and seeing what your encoding is.

I read in a CSV file with Data <- read.csv(file="FileName.csv",head=TRUE,sep=",") the file containts strings in the 2nd and 3rd columns and each has about 1000 rows. I need to either loop through the strings there looking for strings that would trigger other logic or remove those rows and put them in another array and loop through them in the new array. I can't seem

Hi, Your attempt didn't work because you didn't do what I suggested, which was make sure that your data frame matched the example given in the help for gantt.chart. Here's what you have: > str(cdfg) 'data.frame': 3 obs. of 3 variables: $ c1d1: Factor w/ 3 levels "task 1","task 3",..: 1 3 2 $ c2d1: POSIXct, format: "2018-04-01"

You don't say, but I'd guess you're using Windows. In your code page, the character ? is probably not representable. At some point in the sequence of operations involved in printing the dataframe R puts the string into the native encoding, and since that's impossible on your system, it substitutes the <c5> instead. The fact that you can sometimes display it is because
