Question

我尝试对graphql进行更改以更新现有数据库中的项目。当我尝试执行此突变时，仍然出现错误。

我在项目中添加了“接受”：

我尝试部署架构，但没有任何效果。

% Little function to edit multiple XML files
% New files are copied into the Modified_XML_Files folder
% and original files are not overwritten

% Creation of a new folder
Modified_XML_Files = fullfile(pwd, 'Modified_XML_Files')
if exist([pwd '\Modified_XML_Files'])~=7
    mkdir(Modified_XML_Files);
end

% Copy XML files and move to new folder
copyfile('*.xml', 'Modified_XML_Files')
cd Modified_XML_Files

% List of XML files to modify
XML_Files = dir(fullfile('*.xml'));
XML_Files_Names = {XML_Files.name};

% Loop and delete text between xmlns= and the next space inclusively
for k = 1 : length(XML_Files)
    Old_File = XML_Files_Names{k};
    file_text = textread(Old_File, '%s', 'delimiter', '\n', 'whitespace', '');
    file_text = eraseBetween(file_text, "xmlns=", " ", 'Boundaries', 'inclusive');
    New_File = fopen(Old_File, 'w');

    for i=1:length(file_text)
        fprintf(New_File, '%s\n', file_text{i});
    end

    New_File = fclose(New_File);
end

此后，我进行了突变：

type Item {
  id: ID! @id
  title: String!
  image: String
  largeImage: String
  price: Int!
  user: User!
  accepted: String!
}

然后我写了解析器：

type Mutation {
  updateAccepted(id: ID!): Item!
}

当我在操场上执行此功能时，出现此错误

async updateAccepted(parent, args, ctx, info) {
    // 1. Check if the person is logged in
    const { userId } = ctx.request;
    if (!userId) {
      throw new Error('You must be signed in');
    }
    // 2. find the item
    const item = await ctx.db.mutation.updateAccepted(
      {
        where: { id: args.id },
        data: {
          accepted: 1
        }
      },
      info
    );

    // 3. Return the item
    return item;
  },

Kinda无能的atm，请帮助有需要的开发人员：）

问题解决了。问题是我不得不打电话给updateItem而不是updateAccepted。突变类型为Item ...而不是accepted ..

async updateAccepted(parent, args, ctx, info) {
    const { id, accepted } = args;
    // 1. Check if the person is logged in
    const { userId } = ctx.request;
    if (!userId) {
      throw new Error('You must be signed in');
    }
    // 2. find the item
    return ctx.db.mutation.updateItem(
      {
        data: { accepted },
        where: { id: args.id }
      },
      info
    );
  },

快乐的日子

Ctx.db.mutation。“ updateAccepted”不是一个函数。Prisma不会生成突变
