does anyone know if there is a VALIDATE function for a form in cakePHP and view the errors array? i.ve checked the documentation but the only thing i found is the SAVE function, i just need to know if the data i send is valid and review the errors manually.

I have a series of ggplot objects that I'm trying to save to an .rdata file to load into a Markdown document later. The ggplot object itself is quite small (a few KB). But, when I try to save the object as an .rdata file for later retrieval, the resulting .rdata file is now over 8 gigabytes. I've tried saving the plot directly from the GUI, saving as an .rds... Saving as a .pdf or other image results in a normal image of a few KB. I'm stumped, has anyone else encountered this problem? Sample workflow below, I can't provide reproducible code for the problem since I can't upload the dataframe

https://cran.r-project.org/web/packages/formattable/formattable.pdf I've been using the Formattable package to make some nice looking tables in R. I'm trying to save the tables as images (or really any file format) but can't find a command that works. Using the jpeg/png function or dev.copy creates blank documents. Ideally I'd like to be able to save these tables in a loop. Does anyone know how this might be done? data: library(formattable) DF <- data.frame(Ticker=c("", "", "", "IBM", "AAPL", "MSFT"), Name=c("Dow Jones", "S&P 500", "Technology", "IBM", "Apple", "Microsoft"), Value=accounting(c

I am using $resource to retrieve data from the server using query. The server returns an array of objects, which I store in stuklijst . I can send the (updated) contents of stuklijst back to the server by looping through the array and using $save to send each item of the array back to the server. I now want to send all items (the entire stuklijst ) to the server in one go, without using the loop. When trying a $save on stuklijst , Angular throws a "destination.push is not a function" error. How can this be accomplished with $resource ? Here's the code: Service: var stukModule = angular.module(

I want to create a Google Closure Compiler plugin for Eclipse. I already have a popup menu entry to compile a JavaScript file to its minified version. But it would be more than helpful if every time you save a *.js that minified version would be generated automatically. I read/heard about natures and builders, extension points and IResourceChangeListener . But I did not manage to figure out what I should use and especially how to get it to work. Is there a working example of a plugin that does "the same kind of thing" so I can work from that or a tutorial to write such? With the answer below I

I am developing paint app and i save my drawing as png image. For drawing i used canvas that created with a bitmap. it works but image was corrupted. Can any one help me. I didn't check it with a real phone but on the emulator. Is that problem with emulator. I think it has very small processing ability. Am i right? Thank you. Phyrum Tea The emulator works fine. What piece of code did you use to store the bitmap as png? The following works fine in the emulator: Bitmap bitmap = createYourBitmap(); OutputStream stream = new FileOutputStream("/sdcard/test.png"); /* Write bitmap to file using JPEG

Over time I've rolled my own formats for saving and loading object properties but on having to revisit this I'm wondering about using Delphi's own text DFM format. I know tha this is really an 'internal' format, but the reader for it now seems pretty well defined and it copes with all types of property. Has anyone any comments about possible pitfalls? I wouldn't really say that DFM is an 'internal format'. Sure Delphi uses it internally for forms and datamodules, but TReader and TWriter classes that perform streaming are publicly accessible and even documented. So they are clearly intended for
