I'm having problems with image validation, documentation as always doesn't help, so there is my simple validation to check if image was uploaded
$validate = Validation::factory($_FILES)
->rule('file', array('Upload::not_empty'));
But this gives me error
ErrorException [ Warning ]: call_user_func_array() expects parameter 1 to be a valid callback, array must have exactly two members
What could be causing this error?
The 2nd argument for rule is a PHP callback. So this would suffice because the not_empty method in the upload class is static:
rule('file', 'Upload::not_empty');
You only really need to do the array syntax when the method is not static:
rule('file', array($class, 'method'));

I get many pop up errors like so :
Failed to upload action package to AOG (preview)
Request contains an invalid argument.
The query pattern '$SchemaOrg_Number:numberx $SchemaOrg_Number:number2x $SchemaOrg_Number:number3' contains an undefined parameter (name: 'number2x' type: 'SchemaOrg_Number')
when I try to save my intent.
However when I navigate to test my google action , it seems to be working fine (it recognises the parameters when I give my application the same expression structure that I define in my training phrases)
It shouldn't be a problem , but I would like to submit my app for alpha testing, and when I do so I get an error of a similar nature:
The query pattern '$SchemaOrg_Number:numberx $SchemaOrg_Number:number2x $SchemaOrg_Number:number3' contains an undefined parameter (name: 'number2x' type: 'SchemaOrg_Number')
What is causing this error and how can I try and fix it?
Cheers!
How can I check whether there is a specific parameter inside req.param() in sails.js?
For example, I want to check whether the parameter X_id exists in req.param(). If the parameter exists, then I want to use it. If it doesn't exist, then I want to use a default value instead. I've tried the following code:
X_owner: req.param('X_id') || -1,
But I receive an error when I run this code with out X_id parameter. How can I fix the code?
If you're aiming to use default values for your parameters, I'd suggest using actions2 if you haven't tried. It lets you define parameters (using the inputs' object) and use defaultsTo on inputs you want to have default values for, just like in your models attribute definitions. Using these should help resolve the issue.
As for how to check whether there is a specific parameter inside req.param(), you can use req.allParams() to reveal all current parameters from all sources. These include parameters parsed from the url path, the request body, and the query string in that order.
This is my client Side code:
model.remove('agent',{'text':'online'});
I cant able to remove collection from model,Its shows following error in console
Error: remove must be performed under a collection and document id. Invalid path: agent
From the documentation, it looks like 'path' should be the collectionname.id. In this case, maybe I suppose it should be 'agent.id'.
This blog refers that the path should be in the format collection.documentId.document.

I am getting below error when I run the Orchestration and try to assign value to a promoted property by reading the value of another promoted property.
Error in Suspended Orchestration:
Inner exception: There is no value associated with the property BankProcesses.Schemas.Internal_ID' in the message.
Detail:
I have 2 XSD schemas, 1 for calling a stored procedure and reading its response and another to write it into a flat file. The internal ID returned in the response from SP needs to be passed to a node in another XSD schema to write to a flat file format.
I have promoted an element from the response schema and also promoted an element from the schema to write to flat file. I am assigning the value to promoted propeties as below:
strInternalId = msgCallHeaderSP_Response(BankProcesses.Schemas.Internal_ID);
msgCallSP(BankProcesses.Schemas.Header_Internal_ID) = strInternalId;
But when I run the orchestration I get the error as mentioned above. I have checked the reponse from stored procedure and the reponse XML does contain some value but I am unable to assign that value to another schema. Please advice
Thanks,
Mayur
You can use exists to check the existence of property.
if(BankProcesses.Schemas.Internal_ID exists msgCallHeaderSP_Response)
{
strInternalId = msgCallHeaderSP_Response(BankProcesses.Schemas.Internal_ID);
msgCallSP(BankProcesses.Schemas.Header_Internal_ID) = strInternalId;
}
One scenario that might cause this error is that there is no Header_Internal_ID element in the message you are trying to modify. Can you inspect the message before modification to ensure that there is an element whose value should be changed - drop the message out to a file location, maybe.
If this is the case, then just ensure that you create this element when you instantiate you r message for the first time - even if you initially set it to an empty element.

To check if the property exists, you can use this syntax:
BMWFS.LS.BizTalk.CFS.BankProcesses.Schemas.Internal_ID exists msgCallHeaderSP_Response
However, if the case is that the source field would always be there, you have to work backwards to find out why the Property is not appearing on the Context.
If it's coming from a Port, is the message passign through an XmlDisassembler Component? If it's coming from another Orchestration, are you actually setting the Property?
The easiest way to look at the Context is to route the Message, msgCallHeaderSP_Response, to a Stopped Send Port. You can then view the Context in BizTalk Administrator.
Scenario:
Consider the following code:
var querystring = require('querystring');
var ParamsWithValue = querystring.parse(req._url.query);
Then I am able to read any query string's value.
E.g: If requested string is http://www.website.com/Service.aspx?UID=Trans001&FacebookID=ae67ea324
I can get the values of query string with codes ParamsWithValue.UID & ParamsWithValue.FacebookID respectively.
Issue: I am able to get the values of any number of parameters passed in the same way described above. But for second time onwards I am getting the following error in response on browser.
Error:
{"code":"InternalError","message":"Cannot read property 'query' of undefined"}
Question: What is wrong in the approach to read the query string from the URL.
Note: I don't want to use any frameworks to parse it. I am trying to depend on built-in modules only.
Update: It responds correctly when the value of any of the parameter is changed. But if the same values requested again from even different browser it throws same error.
I think you need req.url rather than req._url.
req.url is a string, if you want a URI instance use require('url').parse(req.url)
So, you should finally have:
var ParamsWithValue = querystring.parse(require('url').parse(req.url).query);
Edit: I corrected a typo in point 1, the last req.url -> req._url
