agrochain's Issues

How to run that dapp?

Thanks for your kind sharing of this repo, I am just fresh to dapps development. I have configurated Truffle and Ethereum on my PC, now I want to learn how to develop a dapp, could you please tell me how to run your AgroChain dapp on my local computer?
and I have a environment like this:
OS: Ubuntu 16.04
node --version: v8.9.3
npm --version: 5.6.0
truffle version: Truffle v4.0.4 (core: 4.0.4)
Solidity v0.4.18 (solc-js)

truffle test Using network 'development'. 0 passing (0ms)

jscript get() call does not retrieve data

Team,
I am new to the blockchain world, so this could well be a newbie issue, with that said, I really would like to see this work. I am using the Ganache/Truffle framework. The default for Ganache is port 7545 rather than 8545. I've changed the port value in all of the other *.js objects to reference port #7545. I also followed the "Important_Instructions" text file, thus changing the connection address to the default one published after the migrations. I do see the Network ID appear when the localhost:3000 web page appears. Please advise on what else I should be looking for.

I cannot seem to find Line Number 43820 from 'Important Instructions.txt' file

I am reading the 'Important Instructions.txt' file and it states:

In src directory --> app.js

Line number 43820 --->

change the variable conaddress = "0x733fa0cfc10adee89e2e426b133f7b40706d5ea3";

I can find app.js, however, I cannot seem to find line number 43820 and conaddress. I think there might be a mistype.

Transaction status shows success when it is revoked by chain reorganization

Bug Report

Description

When submitting farmer details, the scenario that the transaction is revoked due to chain reorganization is not considered.
When the transaction is executed but then revoked, status of the transaction still shows success while the transaction is still is transaction pool.

Reproduce Steps

1. send transaction to submit farmer details
2. When the transaction is executed, UI shows transaction succeeds
3. Let blockchain reorganize by importing a side chain
4. The transaction is revoked and returns to transaction pool.
5. The transaction still shows success in UI.

Expected Behaviour

If the transactions revoked by chain reorganization, it should reveal on UI.
