Hyperldeger Fabric Composer : Essential ACLs




hyperledger composer essential acls
hyperledger composer essential acls 


If you don't know how to setup hyperledger composer read this post.
I almost gave 5 days 😅  to add an asset via participants other than Admin. As I get an error about some permission for that kind of participant I was adding that resource permission to that participants ACL.

.. .. And I have almost given 8 system permissions including network and asset registry resources. Actually, I don't find a solution on any blog or documentation, but  (guess what? 😳) I found a solution on someone's GitHub sample project.

That I am sharing here.

Essentials ACL's that has to be applied

[ at least in case you are going to use composer-rest-server ]


// Give NetworkAdmin User Full Access To Every Resouces //

rule NetworkAdminUser {

    description: "network administrators full access to user resources"
    participant: "org.hyperledger.composer.system.NetworkAdmin"
    operation: ALL
    resource: "**"
    action: ALLOW
}

rule NetworkAdminSystem {

    description: "network admin full access to system resources"
    participant: "org.hyperledger.composer.system.NetworkAdmin"
    operation: ALL
    resource: "org.hyperledger.composer.system.**"
    action: ALLOW
}

// This is a critical ACL. It provides every participant access to // Just composer system. 

// on top of which your system & composer-rest-server going to work.

rule SystemACL {

    description:  "System ACL to permit all access"
    participant: "org.hyperledger.composer.system.Participant"
    operation: ALL
    resource: "org.hyperledger.composer.system.**"
    action: ALLOW
}

// After upper three rules, you can define your systems ACL's 
rule MyRules {
    description:  "System ACL to permit all access"
    participant: "com.mchampaneri.project.Garage"
    operation: ALL
    resource: "com.mchampaneri.project.Car"
    action: ALLOW
}


Hope You will find this useful.

Firebase - update a spacific fields of single element of object of array in firestore

Firebase - update a spacific fields of single element of object of array in firestore  Its actully advisable to use map instead of array when ever it is possible. But, there are cetain cases where you don't have option to do so.  For example, you are directly saving the response from some outer source without any modification and they send you an array. In this case you will have array to work with. Firestore does not support array here is why  "bad things can happen if you have multiple clients all trying to update or delete array elements at specific indexes. In the past, Cloud Firestore addressed these issues by limiting what you can do with arrays " For more details information you can refer to Kato Richardson post Best Practices: Arrays in Firebase .  Firestore document having array [ used from stackoverflow question ] Suppose you have array of object something like shown in array. Now you want to update endTime field of the object on the index [1]

Web designers and developers can reuse their experience and expertise in creating modern looking desktop applications. Various GUI frameworks offer different UI declaration and styling languages, such as QML and  XAML (Microsoft WPF) . On the contrary, Sciter allows using time proven, robust, and flexible HTML and CSS for GUI definition and GPU accelerated rendering.   Before using sciter I already tried other alternatives but none of them was satisfactory as an example first i tried andlabs / ui  library   i already have written a post on it. You can read it on post gui programming with golang .  But this library is still under construction and has no support for production apps. Secondly, I go for electron but the problem was my simple calc like the app was of size 150mb. Which is 15mb of go and other was the e
