c# - What is the equivalent of static methods in ColdFusion? -

-

In C #, I have created steady ways to assist me in simple operation. For example: 

  Public Static Class StringHelper {public static string reverse (string input) {// reverse string returns reversed input; }}   
 Then in a controller, I will call it using just:  
  StringHelper.Reverse (input);   
 Now I am using Cold Fusion with model Gum, and I want to do the same thing. However, it seems that there is no concept of stable methods in coldfusion. If I make the CFC like this:  
  component stringheller {public string function reverse (string input) {// reverse string returns inverted input; }}   
 Can I call this method by creating an example of  StringHelper  in the controller, such as:  
  component Controller {Public reverse of zero function {var input = event.getValue ("input"); Var stringHelper = new string helper (); Var reversed string = string heller. Reverse; Event.setValue ("Reversed String", reversed); }}   
 Or there is a place where I can put 'static' CFCs that framework will make an example behind the scenes, so I can use it as if it is static, like How do the Helpers folder work?   
 
 
 No, you are right, there is no concept of stable methods of cold melting. I think most people will solve this problem within the scope of application through the use of a single utility, which starts when the application starts. Therefore, you can have in the CFCC on your app:  
  & lt; Cfset application.StringHelper = createObject ("component", "path.to.StringHelper") />   
 Then whenever you are required to call it from anywhere:  
  & lt; Cfset reversedString = application.StringHelper.reverse (string) />   
 Yes, it is not clear as a steady way, maybe some day we could have something like that. But right now I think that it is as close as you would get.

mysql - BLOB/TEXT column 'value' used in key specification without a key length -

-
I have developed an extension which works up to 1.6 on Magren (I'm trying Enterprise Edition, And I think the community is the same problem, because it is the same code). In my install script, I see the $ installer-> gt; CreateEntityTables ($ this- & gt; getTable ('alphanum / info')); The installation is done until it is not in the _text unit table. It crashed there! It turns out that when I log in to SQL and run it via PHPmyadmin, then this error is: Blob / Text column 'value' is used without the key 'key' . I saw the code there, and this is what is trying to create an index on the value column: -> addIndex ($ this- & gt; getIdxName ($ eavTableName, array ( 'attribute_id array (' attribute_id ',' value ')) - & gt; addIndex ($ this- & gt; getIdxName ($ eavTableName, array (' entity_type_id ' , 'Value')), array ('entity_type_id', 'value')) If there is no if statement is n...

ruby on rails - Convert a Activerecord result with has_one associations into a single hash per record -

-
If I have any results from the Active Records, then I have an array of hashes, if I have a reliable load, then every Each organization hash in record hash has a nested hash of its associated records My question is, is there a quick rail system that allows you to merge these nested hashes into a hash per record? An analogy will be changing the records table rows Another resemblance will be converted into a hash at one level of nested hashes. approach 1: select them in the section Include class user has_one: profile end is for square profile: user # street 1, street 2, city etc. end profile = profile.junks (user :). Selection ("User. *, Profile. *") All profiles. First.login Approach 2: Use delegation for class profiles : User # Street 1, Road 2, City etc. Representative: Name ,: name =,: email,: email = ,: from = to & gt; : End of user

javascript - Read complete data from stream from onMessage -

How to read event.data from a web site entirely using javascript ? On Message: Function (Event) {var msg = event.data; Warning (msg); } In the above code, variable msg shows only partial data How to obtain complete data from websicet server? event.data contains complete information; It depends only on your output how much you will see. A warning box only contains a special number of characters, because more characters do not fit in the warning box only. Warning ing is not a good practice to display large data. A more convenient way to save the length and to check that, for example: On Message: Function (Event) {var msg = event.data; Warning (msg.length); } The length should be just the right length, that is the length of the characters you sent.
