React/Redux Can't update initial state / undefined problem
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
I am trying to update my state and getting it to render.
Below I am calling my state from the reducer.js file and displaying the initial list fine.
<div className={classes.resultborder}>
{this.props.transInput.map(data => {
return (
<Inputs
key={data.id}
xParty={data.xParty}
zParty={data.zParty}
yAction={data.yAction}
amount={data.amount}
deleteItem={() => this.deleteItem(data.id)}/>
);
})}
</div>
At the bottom of my parent app, I have
const mapStateToProps = state => {
return {
transInput: state.transactionInputs
};
};
const mapDispatchToProps = dispatch => {
return {
submitResults: () => dispatch({type: 'SUBMIT', x: {
xParty: 'Henry',
yAction: 'Funds',
zParty: 'Elizbath'
}})
};
};
export default connect(mapStateToProps, mapDispatchToProps)(Transactions);
I have hard coded my submitResults because I have not yet been able to update my state and display, this is for simplicity.
I am calling submitResults in a button
submitResults={this.props.submitResults}
Now below is my whole reducer
const initialReducer = {
transactionInputs: [
{id: 1, xParty: "statePaul", yAction: "Funds", zParty: "stateSandra", amount: 100},
{id: 2, xParty: "stateEmily", yAction: "Loans", zParty: "stateJohn", amount: 200},
{id: 3, xParty: "stateMatt", yAction: "Repays", zParty: "stateMicheal", amount: 300},
],
emptyInputs: false,
toggle: false
};
const reducer = (state = initialReducer, action) => {
console.log(initialReducer.transactionInputs);
if(action.type === 'SUBMIT'){
return{
...state,
xParty: state.xParty.concat(action.x)
}
}
return state;
};
export default reducer;
When I press te button to run submitResults I get the following error message TypeError: Cannot read property 'concat' of undefined
I want to be able to update my initial state and have it displayed (currently I do believe if I can get the initial state to update then the display will re-render fine).
I am not completely sure why this is not working but I do believe it's in my reducer.js file has something to dow ith how I'm returning my state.
I apprentice any suggestions.

xPartyis not ininitialReducerbut rather it is a key inside of thetransactionInputsarray element(s). So this would make more sensestate.transactionInputs[0].xParty. The error is correct, there is noxPartykey in the objectinitialReducer.

Okay, is the error this line then ` xParty: state.xParty.concat(action.x)` ? How would I go about fixing it? I tried ` transactionInputs: state.transactionInputs.concat(action.x)` but it did not work.

Its hard to tell how to fix it without knowing much of your requirements. Based on what you postedaction.xdoesn't look like an array, it's an object, andtransactionInputsis an array of objects. Youconcattwo arrays, but concating an array to an object won't work. Changingaction.xto be an array may solve your problemx: [{ xParty: 'Henry', yAction: 'Funds', zParty: 'Elizbath' }]

action.x doesn't look like an array, it's an object, and transactionInputs is an array of objects. You concat two arrays, but concating an array to an object won't work. Changing action.x to be an array may solve your problem x: [{ xParty: 'Henry', yAction: 'Funds', zParty: 'Elizbath' }]– Annjawn

In the reducer.js file, under the action type of 'SUBMIT', I had the following code:
if(action.type === 'SUBMIT'){
return{
...state,
xParty: state.xParty.concat(action.x)
}
}
return state;
But I have that the bug was with the line ...state, and now I have ...state.transactionInputs,
if(action.type === 'SUBMIT'){
return{
...state.transactionInputs,
transactionInputs: state.transactionInputs.concat(action.x)
};
}
SIDE NOTE
When I was trying to figure out what was wrong, I used console.log(initialReducer.transactionInputs) to see if the state was updating but I reliased that was I getting thr initial state and not the current one which was state. So for the console.log I should of used console.log(state.transactionInputs);, I would have solved this much sooner.
Just a side note :)
