eduSteem developement update (Week 3b)

Repository

New Feature: User Profile

With many of the core features working I've turned my attention to the "Steem" part of eduSteem. Currently the Steem integration is limited to the setup and retrieving relevant information about the account. The implementation also gives the users a place to update their eduSteem profile which will be needed for planned features listed below.

The planed feature set includes:

Educators

• Sharing lesson plans and activities to the Steem network.
• Searching and "Downloading" lesson plans and activities from Steem
• Being able to vote, comment, reply on the lesson plans and activities.

Students

• Upload finished projects to the Steem network
• Share parent or guardian account for any rewards given
• Weekly semi-automated "report" for those that are investing in the child's future through liking their submissions.

Implementation

Pull requests: 7,8

Using the Steemit API found here I was able to build a simple function set and retrieve data from the Steem block chain. Using XMLHttpRequest() to create a connection to the server I simply reformatted the returned data into various variables for the interface to access and display. For full code reference of my Steemit functions check out steemit.js

The interface is built in the same fashion as all QML based interfaces and can be found in the Profile.qml file.

The Steem information is stored locally in the program's private data store, and written to the database using the saveSteem function found in general.js the function in its entirety is pasted below.

function saveSteem(userid, type, steemAccount, steemKey) {

    var pull = ""

    var data = [userid,type,steemAccount,steemKey,""]
    var dtable = "INSERT INTO Steem VALUES(?,?,?,?,?)"

    db.transaction(function (tx) {
        tx.executeSql(
                    'CREATE TABLE IF NOT EXISTS Steem (id TEXT, type INT,data1 TEXT,data2 TEXT,data3 TEXT)')

        pull = tx.executeSql("SELECT * FROM Steem WHERE id='" + userid + "'")

        if (pull.rows.length !== 1) {

            tx.executeSql(dtable, data)
        } else {
            tx.executeSql("UPDATE Steem SET data1='"+steemAccount+"', data2='"+steemKey+"' WHERE id='"+userid+"'")
        }
    })
}

eduSteem is going through a development sprint. These weekly updates, help keep me on track as well as giving those that are interested detailed reporting of my progress. The goal is to have it ready for use in a small school setting by the end of July. For further reading check out these other posts here on Steemit.
