To supply a parameter that far down the string of arguments, you have to also supply the expected variable it is to define. So this: .fontStyle(‘NimbusSansNovCon-Reg’, 12px, @letter-spacing: 0.1em); Produces this (note how color, font-weight, and font-style used the defaults): font-family: ‘NimbusSansNovCon-Reg’; font-size: 12px; color: #ffffff; font-weight: normal; font-style: normal; letter-spacing: 0.1em;
Try this: redirect_to(edit_multiple_items_path(:page =>2), :notice => ‘items updated’)
Java makes an assumption that you want to automatically convert the Array args to varargs, but this can be problematic with methods that accept varargs of type Object. Scala requires that you be explicit, by ascribing the argument with : _*. scala> def bar(args:String*) = println(“count=”+args.length) bar: (args: String*)Unit scala> def foo(args:String*) = bar(args: _*) … Read more
See Window / Preferences / Java / Compiler / ErrorsWarnings / Unnecessary Code / Value of parameter is not used In old versions (before Eclipse Juno?) the setting was called “Parameter is never read”. Note: If there is a valid reason for not using a parameter (e.g. it is used via reflection), you can suppress … Read more
The Framework Design Guidelines (a book by Krzysztof Cwalina and Brad Abrams) recommend to avoid both ref and out parameters. AVOID using out or ref parameters. Using out or ref parameters requires experience with pointers, understanding how value types and reference types differ, and handling methods with multiple return values. Also, the difference between out … Read more
Also you can use PostrgreSQL support for array storing. (If you’re using PG of course). Your migration will look like that: add_column :table_name, :column_name, :string, array: true, default: [] But don’t forget about validations.
You can use the parameter attribute to declare multiple parameter sets. You then simply assign parameters that are mutually exclusive to different parameter sets. EDIT: This is also documented in ‘about_Functions_Advanced_Parameters’, under the section “ParameterSetName Named Argument”. This is how different sets of parameters is handled with cmdlets like Get-Random (which has mutually exclusive parameters): … Read more
As others have noted, you cannot have a field of “ref to variable” type. However, just knowing that you cannot do it is probably unsatisfying; you probably also want to know first, why not, and second, how to get around this restriction. The reason why is because there are only three possibilities: 1) Disallow fields … Read more
To help guard against SQL injection, I normally try to use functions wherever possible. In this case, you could do: … SET @TableName=”<[db].><[schema].>tblEmployees” SET @TableID = OBJECT_ID(TableName) –won’t resolve if malformed/injected. … SET @SQLQuery = ‘SELECT * FROM ‘ + QUOTENAME(OBJECT_NAME(@TableID)) + ‘ WHERE EmployeeID = @EmpID’
