Bug: Database is locked on article create

Steps to reproduce:

1. create article (POST /article) with title = "string"
2. try the same request . You will get an error

   {
       "errors": {
           "body": "UNIQUE constraint failed: articles.slug"
       }
   }

3. As transaction has started and not rollback or commit, when you run the same request, you will get

   {
       "errors": {
           "body": "database is locked"
       }
   }

Solution is to add tx.Rollback() before returning error in create

Access to store from middleware

Thank you very much for your example, I am following the design pattern, but I am facing a problem, I implemented a function to check data in the db in a middleware, but I do not know how to access the store from the router / middleware route, could you give me an example of how to do this?

Here is my example code:

public, err := publicKey(c)
			if err != nil {
				return c.JSON(http.StatusUnauthorized, utils.NewError(err))
			}
			secret, err := secretKey(c)
			if err != nil {
				return c.JSON(http.StatusUnauthorized, utils.NewError(err))
			}
			company := model.Company{
				Keys: model.Keys{
					Public: public,
					Secret: secret,
				},
			}
			resp, err := store.CompanyStore{}.GetByKeys(&company)
			if err != nil {
				return c.JSON(http.StatusForbidden, utils.NewError(ErrKeysInvalid))
			}
			c.Set("company", resp)
			return next(c)

add tests

the testing part is really important I think. You should add it.

fatal error: unexpected signal during runtime execution

Hi,

Thank you for your work on this repo. Currently I'm running into the following problem when installing and running this project. Is there a missing package in this go.mod?

I'm using golang 1.17. and I'm getting the following error when running go run main.go

fatal error: unexpected signal during runtime execution

Access to store from middleware

Thank you very much for your example, I am following the design pattern, but I am facing a problem, I implemented a function to check data in the db in a middleware, but I do not know how to access the store from the router / middleware route, could you give me an example of how to do this?

Here is my example code:

public, err := publicKey(c)
			if err != nil {
				return c.JSON(http.StatusUnauthorized, utils.NewError(err))
			}
			secret, err := secretKey(c)
			if err != nil {
				return c.JSON(http.StatusUnauthorized, utils.NewError(err))
			}
			company := model.Company{
				Keys: model.Keys{
					Public: public,
					Secret: secret,
				},
			}
			resp, err := store.CompanyStore{}.GetByKeys(&company)
			if err != nil {
				return c.JSON(http.StatusForbidden, utils.NewError(ErrKeysInvalid))
			}
			c.Set("company", resp)
			return next(c)
