upgrade

I can't figure out how to upgrade this code from Rails 2 to Rails 3: <% remote_form_for(item, :update => 'div_id') do |f| %> ... I tried this: <%= form_for :item, :remote => true, :url => { :controller => "items", :action => "create" }, :update => 'div_id' do |f| %> ... It creates the new item but it fails in updating the content within <div id="div_id"></div> tags. It seems Rails 3 no longer supports the " :update " option for a remote form_for . Any suggestion? You could use RJS, but that's being deprecated too (and for good reason). The simplified, best-practices way to handle this in Rails

I have Eclipse 2018-09. My impressions was that Eclipse was moving to a rolling quarterly release, and by that I presumed I'd magically be offered updates every quarter to the newest. But now that 2018-12 is out, my instance does not detect any new updates. Looking at the update sites in Windows -> Preferences, Install/Update -> Available Software Sites (incompletely listed below), I notice they seemed to be pinned to specific versions: The Eclipse Project Updates : http://download.eclipse.org/eclipse/updates/4.9 The Eclipse Project Updates : http://download.eclipse.org/eclipse/updates/4.9

I'm upgrading a big web site project from Visual Studio 2010 to 2012. Throughout my project, I have table elements with the runat="server" attribute. Many of these have thead elements inside of them. When I open it in 2012 and and try to build, I get the following error: Value of type 'System.Web.UI.HtmlControls.HtmlGenericControl' cannot be converted to 'System.Web.UI.HtmlControls.HtmlTableRow' Removing the runat="server" attribute or commenting out thead fixes it. Commenting out only the tr element inside of thead does not fix it. Here is a simplified example that reproduces the problem: <%@

This question already has answers here : How to upgrade csproj files with VS2017 (3 answers) I have two projects in VS2015 One .NET Core (project.json, xproj) One regular .NET csproj When I open project 1 with VS2017, it nicely migrates to the new csproj format.

I have written a Windows service in C#. I have since installed it on my machine, and it runs just fine. When you install a service, does the exe get copied somewhere? Or does it point to my bin folder? This is for me to know that when I update my code from time to time, do I have to uninstall and re-install my service to update it? If the Windows service's location has not changed and the name of its executable has not changed, you should not have to uninstall and reinstall it. You can simply stop the service, update its executable with a new version, and start it again. This approach worked
