【中文标题】阿波罗突变“在这种环境中，分配的来源必须是一个对象”

【英文标题】：Apollo mutation "In this environment the sources for assign MUST be an object"

【问题描述】：

有人知道在突变期间如何处理这种错误吗？

在这里发生：

const RepositoryItem = ( repository, selectedRepositoryIds : IProps) => 
    const isSelected = _.includes(selectedRepositoryIds, repository.id);
    return (
        <View style=Theme.para>
            <View style=Theme.horizontalTopLeft>
                <Mutation
                    // @ts-ignore - mappings incorrect for Mutations
                    mutation=SelectRepository
                    variables= id: repository.id, isSelected >
                    (toggleSelectRepository: ((id: string, isSelected: boolean) => void)) =>
                        (<Switch value=isSelected
                            onValueChange=(val) => 
                                const id = repository;
                                toggleSelectRepository(id, val);
                                 />)
                </Mutation>

            </View>
        </View >);
;

【问题讨论】：

你能分享你的问题吗？或者具体来说，toggleSelectRepository 是你的变异函数的名称吗？

谢谢@MohsenZareZardeyni - 然而问题是我的解析器参数。查看答案

【参考方案1】：

问题是使用参数调用解析器。这些已经作为variables 提供，所以（有点令人困惑）解析器toggleSelectRepository 应该在没有任何参数的情况下调用。

对此进行测试，我发现参数确实按照variables 中的规定提供。

        <Mutation
            // @ts-ignore - mappings incorrect for Mutations
            mutation=SelectRepository
            variables= id: repository.id, isSelected >
            (toggleSelectRepository,  loading, error : GenericResponse) => 
                if (error) 
                    return <FormValidationMessage>error.message</FormValidationMessage>;
                
                if (loading) 
                    return <BusyIndicator isBusy message='One sec..' />;
                

                return (<Switch
                    value=isSelected
                    onValueChange=() => toggleSelectRepository() />);
            
        </Mutation>
