search for: is_empty

So I''ve pretty much followed the steps in the video tutorial on RoR.com for creating a small app, to search for photos on flickr.com - all is good, and works as intended to.. How would I go about adding validation, so if no tags are specified it will fail. I know I have to use validates_presence_of :tags - but not in the controller.. so I tried to generate a model called

Hello, i have two models : class Container < ActiveRecord::Base has_many :bottles end class Bottle < ActiveRecord::Base belongs_to :container def self.find_all_from_container(container) container.bottles.find(:all) end end i was asking myself if there was a better way to write the function find_all_from_container : i can call it from an instance of Container but

Hi, I''ve just been having a look at the scriptaculous drag-n-drop library, which looks exceedingly good. I''m running across a show-stopper here, though - something that''s cropping up in both the online demos and my own test scripts. If I set up two lists so that I can drag items between them, then if either list becomes empty, I can''t drag elements back into

I ran into this issue too. My solution was to add an "onUpdate" function to the sortable that tests the container to see if it''s got any children or not: function is_empty(container) { if ($(container).hasChildNodes()) { Element.removeClassName($(container),''empty''); } else if (!$(container).hasChildNodes()) { Element.addClassName($(container),''empty''); } } I was using this for 2 sortable (UL) lists - my class for the &quot...

...benefit of range based for loops. It doesn't enable anything fundamentally new, but improving readability of C++ code is welcome. This is easy to punt (and I won't be especially bothered if that's what we do), but it also seems like it would be easy to implement our own version (llvm::is_empty?) and replace it when the committee decides on something, the same way we did with llvm::move? Is there any reason not to follow that approach? Cheers, Lang. On Thu, Mar 20, 2014 at 2:31 PM, Chandler Carruth <chandlerc at google.com>wrote: > Since Richard first poked me about this, I...

Hi all, As RFCs go this is short and sweet - I think it would be nice to add an empty method to iterator_range. Something like: bool empty() const { return begin() != end(); } My motivation is to make the 'if' test at the start of this common pattern tidier: if (!collection.empty()) // initialization... for (auto& c : collection) // do something for each c. which I think that

Hi, this series improves virt-dib, adding some upstream changes, and refactoring the handling of output formats. Thanks, Pino Toscano (6): dib: clear up "already provided" message dib: add --checksum dib: pass custom mkfs options after the filesystem type dib: refactor output formats handling dib: clarify "output:" lines in --machine-readable documentation dib:

Hi, this work makes supermin use the rpm library instead of invoking rpm directly. This, together with a needed refactoring of the dependency resolution, should help in make supermin faster on rpm-based systems. Surely the patches will still need polishing, especially for behaviours of newly added stuff, but at least it's a good starting point. Noting that you need rpm-devel on most of rpm

This patch series adds the needed support for this extension to the various parts of mesa to finally enable it for nvc0. Dave Airlie (1): glsl: lower cull_distance into cull_distance_mesa Tobias Klausmann (10): glapi: add GL_ARB_cull_distance mesa/main: add support for GL_ARB_cull_distance mesa/prog: Add varyings for arb_cull_distance mesa/st: add support for GL_ARB_cull_distance

Hello everyone, 9.0.0-rc2 was tagged yesterday from the release_90 branch at r368683. In the Git monorepo it's available as the llvmorg-9.0.0-rc2 tag. Source code and docs are available at https://prereleases.llvm.org/9.0.0/#rc2 Binaries will be added as they become available. The tag went in roughly one week behind schedule (see "Upcoming Releases" at https://llvm.org), but

We can use the setfiles(8) command to relabel the guest filesystem, even though we don't have a policy loaded nor SELinux enabled in the appliance kernel. This also deprecates or removes the old and broken SELinux support. This patch isn't quite complete - I would like to add some tests to the new API. I'm posting here to garner early feedback. Rich.
