当我运行heroku run rails db:migrate时，我遇到了这个错误

rails aborted!
StandardError: An error has occurred, this and all later migrations canceled:

PG::UndefinedTable: ERROR:  relation "matches" does not exist
: CREATE TABLE "picks" ("id" bigserial primary key, "week_score_id" bigint, "picked_team_id" bigint, "match_id" bigint, "created_at" timestamp NOT NULL, "updated_at" timestamp NOT NULL, CONSTRAINT "fk_rails_60b2712d81"

)

sqlite的开发和pg的生产

我猜我的表关系不正确

首先，我认为这个问题是因为我使用

match:references

生成模型，所以在我拥有的

属于：match

的模型和我拥有的

t.references:match

迁移文件中。我将所有所属对象切换为：match\u id，并更改了迁移文件

match\u id:integer

和

运行rails db:reset

但它仍然不起作用：（

在创建

匹配项之前，您尝试创建picks
表。lol起作用了。使用匹配：引用
安全吗？您的意思是t.references:match
语法吗？
