Virtual attributes in Rails 4 from Rails 3 -

-

I am making a Rail 4.10 app and I am using code from my Rail 3.2 app. In this app, I get a form where I add a virtual attribute which is called Group_ID and then use after_save to add a group for the user.

In my 3.2 code: 

  attr_accessor: group_ids after_save: add_groups def add_groups if group_ids.present? Self.assignments.user_groups.delete_all group_ids.reject! (And: empty?) Group_ids.each do | Group | Assignment = assignment.Nana Assignment.Signable_ID = Group Assignment.Signable_type = "User Group" assignment. Backend_user_id = self.id self.assignments & lt; & Lt; Assignment end and end   
  In my 4.10 code:   
  Controller: params.require (: backend_user) .permit (: First name, last name, group_ids)   
 How can I use the Add_groups method in 4.10?   
 
 
 It looks like the  group_ids  in the controller code is correctly whitelisted Not being added, which results in  group_ids  is not being set which will be in your  after_save  callback in  group_ids.present?  Returning status  false  Therefore, no statement in the callback is executed.  
 To minimize it,  after_save  callback  add_groups  is executing but it is not doing anything  
 it To resolve, you should whitelist  group_ids  in your code control code:  
  parameter is needed (backend_user). Paramet (: First Name, Last Name, Group_ID => [])

ios - Adding an SKSpriteNode to SKScene from a child SKSpriteNode -

-
I have a SKScene where I am adding an SKSpriteNode I have subclassed the SKSpriteNode class to create this node. In the subclass I am defining some SKActions on Sprite. What do I want to do when the end of this phantom ends the SKAction sequence, then I add a new Prayer node to this scene. How is this possible. The following code is mine: The code for the sequence is that I'm running on the Scansprinitode subclass (TEMissileNode): - SKAction * moveDown = [SKAction moveToY: Self.position.y - 20 Duration: 0.2]; SKAction * animation = [SKAction animateWithTextures: textures timePerFrame: time / 7]; SKAction * moveMissileProjectile = [SKAction Moving: Pointoffscreen Term: Time]; SKAction * group = [SKAction group: @ [animation, movement projectile]]; SKAction * Sequence = [SKAction Sequence: @ [Hilldown, Group, [SKAction removalFromParent]]]; [Self run action: sequence]; From the main scene, I call those actions that execute these tasks TEMissileNode * missile = [tmissil...

Matlab transpose a table vector -

-
An embarrassing simple question seems to be, but how can I move a Matlab table vector? aTableT = aTable '; I tried a standard syntax for the simple interaction of a line vector to a line vector aTable : ATableT = reshape (aTable, 1, Height (aTable)); and aTableT = rot90 (aTable); According to the head, the last time table should work for table, see. However, I get this error code: Error type in using table / permit (line 396) Undefined function 'permute' for the input arguments. Error in rot 90 (line 29) b = magnitude (b, [2 1 3: ndims (a)]); NB: fliplr is not useful either pretty sure I have covered clear angles - any ideas? Thanks! Try changing your table into an array, move it, then back to a table In other words, try doing this: aTableArray = table2array (aTable); ATableT = array 2table (aTableArray. '); I have also read the document for rot90 , and it says that rot90 is definitely working for tables Do, and I find you...

c# - Textbox not clickable but editable -

-
I have a small form with 10 text boxes, I have set them in the correct tab order. I want them on my tab service I was wondering if there is a way to set the text box so that they can be selected for editing until they are tabbed. That is ... I do not want the end user to edit the text box to click on them, I just want to make them editable through tabu. this should do the trick public partial category poor text box: Text Box {Safe Override Zero WndProc (Ref: Message Message) {if (m.msg == (Int) WM.LBUTTONDOWN) {Return; // mount down events} base.WndProc (ref m); }} Window message enum can be found. How to do this without anherizing: text box : class EatMouseDown: netwindows {safe override zero WndProc (ref message message) {if (m.msg == (int) WM.LBUTTONDOWN) {return; } Base.WandProc (Ref M); }} Safe Override Zero Onload (EventEurge E) {base.OnLoad (e); How to do this without any part: left a clean part, whatever is important, this can be a buggy but it works R...
