cube.js 加入编译错误与任何允许的类型都不匹配

Question

I am new to cube.js and have been working through the documentation and can't seem to figure out why I get this error. Any ideas? I am joining two tables, one contains daily data and the other table contains attributes that I would like to use for segmenting data.

I was able to generate the schema nearly entirely from the postgres tables, the only changed I had to make were to tag the columns as primary key.

postgres ddl

drop table if exists daily_volumes;
drop table if exists wells;

create table if not exists wells (
    id integer not null,
    well_name varchar(255),
    api_10 varchar(13),
    area varchar(255),
    run varchar(255),
    engineering_id varchar(50),
    accounting_id varchar(50),
    active_flag int,
    primary key (id)
);

create table if not exists daily_volumes(   
    well_id integer not null,
    record_date timestamp not null, 
    oil_prod_bbl float not null,
    water_prod_bbl float not null,
    gas_prod_mcf float not null,
    primary key (well_id, record_date),
    constraint fk_well_id foreign key (well_id) references wells(id)
);

cube.js error

Error: Error: Compile errors:

Possible reasons (one of):

Answer 1

Setting primaryKey to true will change the default value of the shown parameter to false. If you still want shown to be true — set it manually.

Answer 2

I think the issue was that you used primary_key (snake case) instead of primaryKey (camel case), as described in docs: https://cube.dev/docs/schema/reference/dimensions#primary-key

I also have to admit that the error message is not very helpful now.
