express - Customize validation message in node.js -

-

I am new to node. Js and I had a problem in the required verification message in the node. I use a simplified CRUD operation with the compound JS app in my app "field id" field "id" field only accepts the integer value then I use the following code in model / user.js I agree. 

  module.exports = function (compound, user) {var num = / ^ \ s * \ d + \ s * $ /; User.validatesFormatOf ('id', {with: num, message: "no number is"}); };   
 This works fine using the code above. But I also want to see if the field is empty or not. Then I change the code a little bit. The modified code looks like this:  
  module.exports = function (compound, user) {var num = / ^ \ s * \ d + \ s * $ /; User.validatesFormatOf ('id', {with: num, message: {empty: "can not be empty", with: "no number is"}}); };   
 The verification message will appear when the field is empty, because "id can not be empty" but when I enter values ​​in the id field other than numbers, the verification error message "id [ Object object] "will be. I think the keyword is not supported with it. To use any other keyword here, "blank" or "m" like I can get the verification message "id number is not there".  
 I have found a solution for this so that the modified version of the user is .js like this:  
  module.exports = function (compound, user) {var num = / ^ \ S * \ d + \ s * $ /; User.validatesPresenceOf ('id', {message: "can not be empty"}); User.validatesFormatOf ('id', {with: num, message: "no number is"}); };   
 The problem with the above code is that it is displaying two validity messages at the same time i.e. The default and custom empty message is appearing at the same time. I need to show only one verification message for a field at a time, is it possible?   
 
 
 This juggling looks like a bug in DB (ORM used by CompoundJS).  
 Consider the following code:  
  var juggling = require ('jugglingdb'); Var Schema = Slippers Sama; Var schema = new schema ('memory'); Var user = schema.define ('user'); Var num = / ^ \ s * \ d + \ s * $ / / User.validatesPresenceOf ('id', {message: "can not be empty"}); User.validatesFormatOf ('id', {with: num, message: "no number is"}); User.validatesFormatOf ('id', {with: num, message: "no number is"}); Var user = new user ({id: ''}); User.isValid (function (valid) {if (valid!) {Console.log ('invalid', user.error);} and {console.log ('valid');}});   
 This will actually generate 3 errors:  
  invalid {id: ['' can not be empty '', 'is empty', ' empty ']}   
 If you add another  User.validatesFormat , it will generate 4 errors it looks like a scoping problem elsewhere In the verification code for jugglingDB, I will post a bug report.  
 For now, maybe you're just the first error ( user.errors [0] ).  Edit:  Seeing this, it is also what you also have to do, because JugglingDB will run all verification tests and will produce an error for all unsuccessful tests.

excel vba - How to delete Solver(SOLVER.XLAM) code -

-
After opening several examples of macro / code written, I suddenly get stuck with a code that seems safe. Solver (SOLVER.XLAM) is doing this notation and I would like to remove it from my system. I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'

I have a UITextView and I change a word like the code at the end of UITextView.text: - (void) Replace TexttechWitWord: (NSString *) word {NSString * currentTextViewText = self.textView.text; CurrentTextViewText = [currentTextViewText stringByReplacingCharactersInRange: NSMakeRange ([self.textView.text length] - [word length], [word length]) withString: word; Self.textView.text = currentTextViewText; } Replacement work is fine, but it runs very slowly and very slowly when the textView now lengthens Is there any better way? I try the replacement range: with text for a week but still stuck. Not to know how to use it to replace it in your case. Please guide! Thanks in advance! This is an important job. As you are using an irreversible string and you are creating a very long string and before Assigned to NSString created from.
