I am using redux with my react application. I am trying to get the data from my reducer but when I am trying to do this. I am getting some error.
Uncaught Error: Given action "RECEIVE_CATEGORY_NAME", reducer
"categoriesReducer" returned undefined. To ignore an action, you must
explicitly return the previous state. If you want this reducer to hold
no value, you can return null instead of undefined.
the logic written is working fine in case of influencersNameReducer but is showing an error for categoriesReducer
home_reducer.js
import { RECEIVE_INFLUENCERS_NAME, RECEIVE_CATEGORY_NAME } from './home_actions';
export const influencersNameReducer = (state = [], { type, influencers }) => {
console.log(influencers)
return type === RECEIVE_INFLUENCERS_NAME ? influencers : state

export const categoriesReducer = (state = [], { type, category }) => {
console.log(type, category)
return type === RECEIVE_CATEGORY_NAME ? category : state

const mapStateToProps = ({ influencersNameReducer, categoriesReducer }) => ({
influencersNameReducer,
categoriesReducer
})
export default connect(mapStateToProps)(InfluencersForm)
You need to modify your reducer as:
export const influencersNameReducer = (state = [], { type, influencers }) => {
switch(type) {
case RECEIVE_INFLUENCERS_NAME:
return influencers;
default:
return state;
}
}
export const categoriesReducer = (state = [], { type, category }) => {
switch(type) {
case RECEIVE_CATEGORY_NAME:
return category;
default:
return state;
}
}
On every action the dispatcher goes to every reducer. Since in your code the influencersNameReducer reducer was not doing anything for type RECEIVE_CATEGORY_NAME thus returning undefined. So you were getting the error. Using switch case is the way to do this.

I need to render plenty of inputs for every name of the array, but the problem is creating dynamically useState const and onChange handler for every rendered input.
I try to create handleChange key for every item in an array and pass it to input onChange but got the "String Instead Fuction" error. How to resolve the problem in another way and also avoid code duplication?
export const myArr = [
{ name: "Crist", data: "crist", color: "lightblue", handleChange: "cristHandleChange"},
{ name: "Ruby", data: "ruby", color: "lightpink", handleChange: "rubyHandleChange"},
{ name: "Diamond", data: "diamond", color: "white", handleChange: "diamondHandleChange"},
];
export const myComponent = () => {
const [cristQuantity, setCristQuantity] = useState(0);
const [rubyQuantity, setRubyQuantity] = useState(0);
const [diamondQuantity, setDiamondQuantity] = useState(0);
function cristHandleChange(event) {
setCristQuantity(event.target.value);
}
function rubyHandleChange(event) {
setRubyQuantity(event.target.value);
}
function diamondHandleChange(event) {
setDiamondQuantity(event.target.value);
}
return (
<>
{myArr
? myArr.map((item, index) => (
<div className="main-inputs__wrapper" key={`item${index}`}>
<label htmlFor={item.data}>{item.name}</label>
<input
type="number"
name={item.data}
style={{ background: item.color }}
onChange={item.handleChange} //???
/>
</div>
))
: null}
</>
);
};
You should create one handler for all inputs, and save values in a object with a key as item.data. Such way: {crist: 1, ruby: 3, diamond: 5}
export const myArr = [
{
name: "Crist",
data: "crist",
color: "lightblue"
},
{
name: "Ruby",
data: "ruby",
color: "lightpink"
},
{
name: "Diamond",
data: "diamond",
color: "white"
}
];
export function MyComponent() {
// Lazy initial state
// https://reactjs.org/docs/hooks-reference.html#lazy-initial-state
const [quantities, setQuantities] = useState(() =>
myArr.reduce((initialQuantities, item) => {
initialQuantities[item.data] = 0;
return initialQuantities;
}, {})
);
// common handler for every onChange with computed property name
// https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Object_initializer#computed_property_names
const handleChange = (event) => {
setQuantities((prevQuantities) => ({
...prevQuantities,
[event.target.name]: event.target.value
}));
};
return (
<>
{Array.isArray(myArr)
? myArr.map((item, index) => (
<div className="main-inputs__wrapper" key={`item${index}`}>
<label htmlFor={item.data}>{item.name}</label>
<input
type="number"
name={item.data}
style={{ background: item.color }}
onChange={handleChange}
value={quantities[item.data] || ""}
/>
</div>
))
: null}
</>
);
}
I haven't actually tested this but this is something I would do which will get you on the way.
export const myArr = [
{
name: `Crist`,
data: `crist`,
color: `lightblue`,
handleChange: `cristHandleChange`,
},
{
name: `Ruby`,
data: `ruby`,
color: `lightpink`,
handleChange: `rubyHandleChange`,
},
{
name: `Diamond`,
data: `diamond`,
color: `white`,
handleChange: `diamondHandleChange`,
},
]
export const myComponent = () => {
const [quantities, setQuantities] = useState({
crist: 0,
ruby: 0,
diamond: 0,
})
const onChangeHandler = ({ name, value }) => {
setQuantities((prevState) => ({ ...prevState, [name]: value }))
}
return (
<>
{myArr.length > 0
? myArr.map(({ data, name, color }, index) => {
// if you need to do an update to push more items to the object for any dynamic reason
if (!quantities.name)
setQuantities((prevState) => ({ ...prevState, [name]: 0 }))
return (
<div className="main-inputs__wrapper" key={`item${index}`}>
<label htmlFor={data}>{name}</label>
<input
type="number"
name={name}
value={quantities.name}
style={{ background: color }}
onChange={(e) =>
onChangeHandler({ name, value: e.currentTarget.value })
}
/>
</div>
)
})
: null}
</>
)
}
You're passing a string (not a function) to onChange which is causing that problem.
To fix it, you can wrap all functions into another object
const onChangeFunctions = {
cristHandleChange: (event) => {
setCristQuantity(event.target.value);
},
rubyHandleChange: (event) => {
setRubyQuantity(event.target.value);
},
diamondHandleChange: (event) => {
setDiamondQuantity(event.target.value);
},
};
and call onChangeFunctions[item.handleChange] like below
export const myArr = [
{
name: "Crist",
data: "crist",
color: "lightblue",
handleChange: "cristHandleChange",
},
{
name: "Ruby",
data: "ruby",
color: "lightpink",
handleChange: "rubyHandleChange",
},
{
name: "Diamond",
data: "diamond",
color: "white",
handleChange: "diamondHandleChange",
},
];
export const myComponent = () => {
const [cristQuantity, setCristQuantity] = useState(0);
const [rubyQuantity, setRubyQuantity] = useState(0);
const [diamondQuantity, setDiamondQuantity] = useState(0);
const onChangeFunctions = {
cristHandleChange: (event) => {
setCristQuantity(event.target.value);
},
rubyHandleChange: (event) => {
setRubyQuantity(event.target.value);
},
diamondHandleChange: (event) => {
setDiamondQuantity(event.target.value);
},
};
return (
<>
{myArr
? myArr.map((item, index) => (
<div className="main-inputs__wrapper" key={`item${index}`}>
<label htmlFor={item.data}>{item.name}</label>
<input
type="number"
name={item.data}
style={{ background: item.color }}
onChange={onChangeFunctions[item.handleChange]}
/>
</div>
))
: null}
</>
);
};
Let me start by saying that you might want to use a library like React Hook Form for this, although, if this is the only form and you don't need all the fancy features (or additional bundle size), you can do it like this as well.
The first step is to store your form data in an Object. After this change, you can use a single useState({}) to store and read your form data and drastically simplifies your handlers.
For example:
export const myArr = [
{ name: "Crist", data: "crist", color: "lightblue"},
{ name: "Ruby", data: "ruby", color: "lightpink"},
{ name: "Diamond", data: "diamond", color: "white"},
];
// generate Object with data and initialValue or empty string
// e.g. `{ 'crist': '', 'ruby': '', 'diamond': '' }`
const getInitialFormValues = (arr) => Object.fromEntries(
arr.map(({ data, initialValue }) => [data, initialValue || ''])
);
export const MyComponent = () => {
const [formValues, setFormValues] = useState(getInitialFormValues(myArr));
function handleChange(event) {
// update the changed form value
setFormValues(current => ({
...current, // other form values
[event.target.name]: event.target.value // updated value
}));
}
return (
<>
{myArr
? myArr.map((item, index) => (
<div className="main-inputs__wrapper" key={`item${index}`}>
<label htmlFor={item.data}>{item.name}</label>
<input
type="number"
name={item.data}
style={{ background: item.color }}
onChange={handleChange}
value={formValues[item.data]}
/>
</div>
))
: null}
</>
);
};

This is the bug I'm having:
enter image description here
And i want to have this result like its shown in Antd docs:
enter image description here
Id really appreciate if you take a look and help me figure out where im wrong
Updated Solution:
I find the issue. In render where you map the columns, you just return the column if it's not an editable column. You can check the code below. I added a check if it's dataIndex === 'actions', then return the following code:
Please Follow the link:
https://react-ts-v3fbst.stackblitz.io
Changes:
1.In columns, i remove the render function from the action object:
{
title: 'Actions',
dataIndex: 'actions',
width: '10%',
},
2. In render function where you map the columns, add the following code before this condition if(!col.editable) {,:
if (col.dataIndex === 'actions') {
return {
...col,
render: (text, record) => {
const editable = this.isEditing(record);
return editable ? (
<span>
<EditableContext.Consumer>
{(form) => (
<a onClick={() => this.saveData(form, record.username)} style={{ marginRight: 8 }}>
Save
</a>
)}
</EditableContext.Consumer>
<a onClick={this.cancel}>Cancel</a>
</span>
) : (
<Space size='middle'>
<a onClick={() => this.edit(record.username)}>Edit</a>
<Popconfirm title='Are you sure you want to delete this product?' onConfirm={() => this.remove(record.username)}>
<a style={{ color: 'red' }}>Delete</a>
</Popconfirm>
</Space>
);
}
};
}
When you click on edit, you set the username as key for that particular row for editing, make sure you have username in each record. I tested this using the following data:
const data = [
{ id: 8, name: 'baun', model: '2022', color: 'black', price: 358, quantity: 3, username: 'brvim' },
{ id: 3, name: 'galileo', model: '20221', color: 'white', price: 427, quantity: 7, username: 'john' }
];
Most important, you should select that attribute as key that is unique in all records. As you are using username, i don't know what is your business logic or data looks like, but technically each record can have same username. So you must select something that would always be unique in your complete data.
I want the default value of my dropdown to be defaultValue={item.taste} (value from match.json) but it's not working... (go to /menu/Menu1 and Pea Soup)
import Select from "react-select";
export default function CustomDropdown({ style, options, defaultValue }) {
return (
<div style={style}>
<Select options={options} defaultValue={defaultValue} />
</div>
);
}
MenuItemDisplay:
export default function MenuItemDisplay() {
const { menuId, itemId } = useParams();
const { match } = JsonData;
const matchData = match.find((el) => el._id_menu === menuId)?._ids ?? [];
const item = matchData.find((el) => el._id === itemId);
const styles = {
select: {
width: "100%",
maxWidth: 150
}
};
const TASTE = [
{ label: "Good", value: "Good" },
{ label: "Medium", value: "Medium" },
{ label: "Bad", value: "Bad" }
];
...
return (
<>
<div className="TextStyle">
{"Taste "}
<CustomDropdown
style={styles.select}
options={TASTE}
defaultValue={item.taste}
//The default value is not working only if it's
//TASTE[0]
/>
</div>
...
</>
);
}
Here the link for the code
As defaultValue you need to pass one of the objects of the TASTE array. You can do this:
<CustomDropdown
style={styles.select}
options={TASTE}
defaultValue={TASTE.find(t => t.label === item.taste)}
/>
I used Ant table to show some information.
https://codesandbox.io/s/proud-architecture-lsb85?file=/src/index.js
I want to customize the position of the checkbox for row selection.
In this application, you can see the header in the following order of checkbox, Name, Age, Address but I want to swap checkbox and Name.
You can add checkbox columns and customize render and titleRender of it to checkbox and then handle the events. if you incounter performance issue you have to add some memoization on columns or evenet handlers.

I have a POST API that when executed needs to render the response result in a div
I am using React.js and Redux
This is the service where the api is stored
const addMP3Request = async (payload) => {
const formData = new FormData();
formData.append("titre",payload.payload.titre);
formData.append("description",payload.payload.description);
formData.append("type",payload.payload.type);
formData.append("file1",payload.payload.fichier1);
const wsResponse = await axios.request({
method: 'post',
url: `http://localhost:3000/api/watson_tones/analyzeMP3`,
data: formData,
config: {
headers: {
'Content-Type': `multipart/form-data`,
'Accept': 'application/json',
}
}
});
return wsResponse;
}
this is my reducer
const INIT_STATE = {
responseData: ''
};
export default (state = INIT_STATE, action) => {
switch (action.type) {
case ADD_MP3: {
return {
...state,
responseData: action.responseData
}
}
default:
return state;
}
}
this is the action :
export const addMP3Action = (titre,description,type,fichier1) => {
return {
type: ADD_MP3,
payload: {
titre: titre,
description: description,
type: type,
fichier1:fichier1
},
};
};

When i console.log(this.props.responseData) I get undefined Do you have any idea ?
I believe your issue is that in your reducer, action has no property responseData. Remember that your action returns an object with properties type and payload. When you pass it to your reducer to update the state, you need to look into action.payload to access the data that was sent in the action.
For example, you might want your reducer to look more like this:
const INIT_STATE = {
responseData: ''
};
export default (state = INIT_STATE, action) => {
switch (action.type) {
case ADD_MP3: {
return {
...state,
responseData: action.payload
}
}
default:
return state;
}
}
