问题 I am working on a project that needs to alter Refinery's WYMEditor behavior a bit. This is easily done by overriding jquery.refinery.wymeditor.js using rake refinery:override and editing it to my own needs, which works fine in development environment. However, when it comes to production, overrides are ignored. That is, the compiled asset just contains jquery.refinery.wymeditor.js from bundle, and editing that file directly there may give the desired effect, but that's just not the way it

问题 I'm trying to format my report and making sure the columns have a correct width and I can't seem to make it happen with auto_width. With this code, this is the kind of report I get . Notice the space that is way to long for an auto_width, since if I double click on each column border in Excel, it correctly resizes, see this picture . Maybe it's the order I'm doing things? This is the code I'm using: workbook = xlsx_package.workbook worksheet_name = 'My Worksheet' xlsx_package.use_autowidth =
