  • Multiple dynamic method calls or declaring a variable in Grails

    - by user303979
    In my view, if I have a situation where I need to use a dynamic method (such as Domain.findByName("name")) in multiple places, would it be better to define a variable with and refer to that, rather than have the dynamic method in multiple places? I know this seems like an obvious answer, but I just wanted to make sure Grails doesn't cache it or something, and indeed two DB calls are being made.

  • Pass a variable into a trigger

    - by Codesleuth
    I have a trigger which deals with some data for logging purposes like so: CREATE TRIGGER trgDataUpdated ON tblData FOR UPDATE AS BEGIN INSERT INTO tblLog ( ParentID, OldValue, NewValue, UserID ) SELECT deleted.ParentID, deleted.Value, inserted.Value, @intUserID -- how can I pass this in? FROM inserted INNER JOIN deleted ON inserted.ID = deleted.ID END How can I pass in the variable @intUserID into the above trigger, as in the following code: DECLARE @intUserID int SET @intUserID = 10 UPDATE tblData SET Value = @x PS: I know I can't literally pass in @intUserID to the trigger, it was just used for illustration purposes.

  • How Can I Reference Multiple Primary Keys For A Vector Type Primary Key

    - by AndreiC
    Hi, I have the following scenario: a table of projects and a table of persons, working on one or serveral projects. Also, I have a project id column (of type int), in the first table, which is a primary key there and I have a vector of project ids, as a column of type int, in my second table (persons), that references primary keys from the first table. What is the correct syntax for referencing multiple primary keys, from a vector foreign key. This is the way I am trying to create the table, but I am not sure what to place at the indicated line: CREATE TABLE Persons( Person_Id int, ..., ProjectsList int[], FOREIGN KEY (ProjectsList) REFERENCES Projects(Project_id) -- not sure what how to define the link here ); I hope my explanations are not over-complicated. Thank you in advance for helping!

  • changing src reference based upon https

    - by spody
    I'm adding a facebook comment widget to a website. I'm placing this widget in a file that is included on everypage. The navigation is relatively linked so it switches back and forth from http and https. But for some reason the comment widget only shows up if both the src linked file and webpage is secure or both the src linked file and webpage is NOT secure. The widget does not display of the src file is secure and the webpage is not secure. So... I've tried this but doesn't work. if (window.location.protocol == 'https:') script.setAttribute('src', 'https://ssl.connect.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php'); } else { script.setAttribute('src', 'http://static.ak.connect.facebook.com/connect.php/en_US') }

  • Setting windows powershell path variable

    - by Vasil
    So I've found out that setting the PATH environment variable affects only the old command prompt, powershell seems to have different environment settings. How do I change the environment variables for powershell (v1)? Note: I want to make my changes permanent, so I don't have to set it every time I run powershell. Does powershell have a profile file? Something like bash profile on unix?

  • Canonical pattern reference in Actors programming model.

    - by Bubba88
    Hello! Is there a source, which I could use to learn some of the most used and popular practices regarding Actor-/Agent-oriented programming. My primary concern is about parallelism and distribution limited to the mentioned scheme - Actors, message passing. Should I begin with Erlang documentation or maybe there is any kind of book that describes the most important building blocks when programming Actor-oriented? Thank you! (Most useful examples would be in Scala or F#)

  • How can I programmically construct the object reference?

    - by Bryan
    Lets just say that I have three textboxes: TextBox1, TextBox2, TextBox3. Normally if I wanted to change the text for example I would put TextBox1.Text = "Whatever" and so on. For what I'm doing right now I would like to something like (TextBox & "i").Text. That obviously isn't the syntax I need to use I'm just using it as an example for what I need to do. So how can I do something like this? The main reason I'm doing this is to reduce code with a loop. Please keep in mind that I'm not actually changing the text of the textboxes I'm simply using that as an example to get the point across.

  • Add $PATH variable via Cocoa App

    - by golfromeo
    I'm trying to write a Cocoa app that makes it easier for Android developers on Macs to create Android apps. When a user presses a button on the app, I want it to add a certain directory to the environmental $PATH variable on the Mac. Is there another way to do this via Cocoa instead of opening up the .bash_profile file and adding the path manually? Thanks for any help in advance.

  • ASP.NET SqlDataSource update and create FK reference

    - by William
    The short version: I have a grid view bound to a data source which has a SelectCommand with a left join in it because the FK can be null. On Update I want to create a record in the FK table if the FK is null and then update the parent table with the new records ID. Is this possible to do with just SqlDataSources? The detailed version: I have two tables: Company and Address. The column Company.AddressId can be null. On my ascx page I am using a SqlDataSource to select a left join of company and address and a GridView to display the results. By having my UpdateCommand and DeleteCommand of the SqlDataSource execute two statements separated by a semi-colon I am able to use the GridView's Edit and Delete functionality to update both table simultaneously. The problem I have is when the Company.AddressId is null. What I need to have happen is have the data source create a record in the Address table and then update the Company table with the new Address.ID then proceed with the update as usual. I would like to do this with just data sources if possible for consistency/simplicity sake. Is it possible to have my data source do this, or perhaps add a second data source to the page to handle some of this? Once I have that working I can probably figure out how to make it work with the InsertCommand as well but if you are on a roll and have an answer for how to make that fly as well feel free to provide it. Thanks.

  • How to reference an anonymous JavaScript function?

    - by ProfK
    I'm trying to call a Page Method using a jQuery 'attached' event function, in which I like to use the closure to keep the event target local, as below, but page method calls declare several 'error' functions, and I would like to use one function for all of them. If, in the below code, I was handling an error and not success, how could I use my single, anonymous handler for all 3 error functions? $(":button").click(function () { var button = this; PageMethods.DoIt( function (a, b, c) { alert(button); }); }); This example passes an anonymous function for the success callback. There is only one of these. If I was passing an error callback, how could I use 'function (e, c, t)' for all 3 error callbacks?

  • Fortran: output format dependent on a variable

    - by Flux Capacitor
    I would like to have a FORTRAN write statement formatted to depend on some variable. For example, I could write: write(*,'(3f15.3,3f9.2)') x,y,z,(var(i),i=1,nvari) where nvari = 3 But, what if, in some cases, I actually have 4 variables (i.e. nvari = 4) I would like to write something like this: write(*,'(3f15.3,nvari(f9.2))') x,y,z,(var(i),i=1,nvari) Now, nvari can be anything and the output will work as I like. How can I make something like this work?
