Description

Just trying to fork this repository to report a bug related to many2many.

[brett--anderson]

I'm also having this problem, and I'm also trying to report a bug related to many2many.

[vivere-dally]

Any update on how to deal with the examples/dal issue?

[YidiDev]

I also have this issue

[henryjcee]

So the issue here as I understand it is that /gen/examples was made a submodule in this commit and as a result the current import strategy doesn't work. I don't know the go mod system well enough to recommend a fix but I've worked around this by cloning gen and using a replace directive to import the examples submodule from my local copy.

Could you please share what is the replace directive? I want to report an issue too.

[henryjcee]

Am just writing up a PR now but I've checked out the gen repo and am using:

replace gorm.io/gen/examples => ../gen/examples

which resolves the /examples submodule correctly. For some reason I can't get this to work by requiring gorm.io/gen/examples v0.3.26 without replacing it with a local version, but I am pretty new to Go and perhaps I'm missing the special sauce for requiring a submod?

[henryjcee]

Have raised an issue to fix what I think is the root cause

[maxant]

I commented out the following in gorm-playground/gen.go:

package main

import (
    "gorm.io/gen"
//  "./gen/examples/dal" <<<<<<<<<<<<<<<<<<<<<<<<<<
)

func generate() {
    g := gen.NewGenerator(gen.Config{
        OutPath: "./dal/query",
        Mode:    gen.WithDefaultQuery, /*WithQueryInterface, WithoutContext*/

        WithUnitTest: true,
    })
//  g.UseDB(dal.DB)  <<<<<<<<<<<<<<<<<<<<<<<<<<

    g.ApplyBasic(Company{}, Language{}) // Associations
    g.ApplyBasic(g.GenerateModel("user"), g.GenerateModelAs("account", "AccountInfo"))

    g.Execute()
}

then run ./test.sh

it fails much later:

2024/10/22 23:31:23 /tmp/gorm-playground/db.go:69

i've solved this problem with these steps:

1. clone github.com/go-gorm/gen

   git clone git@github.com:go-gorm/gen.git

2. find all the "gorm.io/gen/examples" in "import", and replace them with "examples"

before:

import (
    "xxxxxx"
    "gorm.io/gen/examples"
    "gorm.io/gen/examples/xxxx"
)

after:

import (
    "xxxxxx"
    "examples"
    "examples/xxxx"
)

3. run go mod download in github.com/go-gorm/gen/examples

   cd PATH/TO/YOUR/{github.com/go-gorm/gen/examples}
   go mod download

4. update the go.mod in playground

   
   # add this line
   require gorm.io/gen/examples v0.3.25

add this line

replace gorm.io/gen/examples v0.3.25 => PATH/TO/YOUR/{github.com/go-gorm/gen/examples}

5. run test.sh in playgound
