我有一个反应原生组件。我得到了错误:
Cannot update during an existing state transition (such as within `render`). Render methods should be a pure function of props and state.
代码:
import....
class Register extends Component {
static navigationOptions = {
header: null,
};
async handleSubmit(values, customerCreate) {
const { email, password, firstName, lastName, phone } = values;
const input = { email, password, firstName, lastName, phone };
const customerCreateRes = await customerCreate({ variables: { input } });
const isCustomerCreated = !!customerCreateRes.data.customerCreate.customer.id;
if (isCustomerCreated) {
const isStoredCrediential = await storeCredential(email, password);
if (isStoredCrediential === true) {
// Store in redux
// Go to another screen
console.log('test');
}
}
}
render() {
return (
<Mutation mutation={CREATE_CUSTOMER_ACCOUNT}>
{
(customerCreate, { error, data }) => {
return (
<MainLayout
title="Create Account"
backButton
currentTab="profile"
navigation={this.props.navigation}
>
{ showError }
{ showSuccess }
<RegistrationForm
onSubmit={async (values) => this.handleSubmit(values, customerCreate)}
initialValues={this.props.initialValues}
/>
</MainLayout>
);
}
}
</Mutation>
);
}
}
const mapStateToProps = (state) => {
return {
....
};
};
export default connect(mapStateToProps)(Register);
CREATE_CUSTOMER_ACCOUNT 是 graphql:
import gql from 'graphql-tag';
export const CREATE_CUSTOMER_ACCOUNT = gql`
mutation customerCreate($input: CustomerCreateInput!) {
customerCreate(input: $input) {
userErrors {
field
message
}
customer {
id
}
}
}
`;
谁在使用handleSubmit?
当按下时,表单中有一个按钮调用handleSubmit。
这个语法正确 onPress={handleSubmit} 吗?
const PrimaryButton = ({ label, handleSubmit, disabled }) => {
let buttonStyle = styles.button;
if (!disabled) {
buttonStyle = { ...buttonStyle, ...styles.primaryButton };
}
return (
<Button block primary={!disabled} disabled={disabled} onPress={handleSubmit} style={buttonStyle}>
<Text style={styles.buttonText}>{label}</Text>
</Button>
);
};
导出默认 PrimaryButton;
更新 1:
如果我删除customerCreate
(来自 graphql),错误就会消失。这意味着异步等待实际上是正确的,但我需要 customerCreate
