            How can I get the maximum value of a specific day in Gorm?
            Asked 2022-Apr-11 at 10:54

            I have written following code to get the daily maximum of a certain value with GORM.

            1. I pass the current time and get the day's start and end.
            2. I select all values between the day's start and end.
            3. I order the temperatures and get the first.

            You could use the max operation in SQL. Maybe not a more 'GORM' way to do this, but in my opinion a more semantically correct/appealing version:

            Here is list of available tags used in echo. If you want to parse from body, then use json

            • query - source is request query parameters.
            • param - source is route path parameter.
            • header - source is header parameter.
            • form - source is form. Values are taken from query and request body. Uses Go standard library form parsing.
            • json - source is request body. Uses Go json package for unmarshalling.
            • xml - source is request body. Uses Go xml package for unmarshalling.

            You need to wrap time.Time into custom struct and then implement json.Marshaler and json.Unmarshaler interfaces

            I am new to ORM (and GORM) so apologies if this is an obvious question, but it does not seem to be covered by the documentation.

            I will be using the examples from the documentation as a base to my questions

            Q1: Based on how you defined your structs, you don't need an explicit O2M relationship in the Company struct, but when loading Company details, if you want to load all users that are assigned to that specific company, you need to add that field as well. It will need an additional function call like Preload or Joins, but you shouldn't need an explicit definition of this relationship.

            How to handle error of singleton only once

            How to handle error of singleton only once?

            I have a singleton service which could generate error only at first call and then it returns already created instance.

            Service looks like below:



            Answered 2022-Mar-02 at 09:41

            If the error occurs (only once), your databaseSingleton will not be setup. You should return the error in all cases.

            Although this isn't something you can do anything about (since the attempt to initialize databaseSingleton will not be repeated due to the use of sync.Once), you could as well halt the app.

            In fact, there is no point deferring this initialization, you could just do it during package init, and terminate if it fails. And if it succeeds, you could use databaseSingleton without having to check error of the initialization.

            So simply do it like this:

            How to solve /bin/sh: 1: source: not found during making docker image in MacOS(Golang)?
            Asked 2022-Mar-01 at 06:47

            I am just getting started learning docker a few hours ago and I trying to make my own docker image. When I tried to make a Dockerfile and a docker image, I got this error message "/bin/sh: 1: source: not found".

            First of all, I manage my environment variables in .env file. Whenever I change my env file, I run this command $source .env and go build . and then go run main.go. So, I tried to set up my Dockerfile, RUN source.env but I got the error that I mentioned above.

            I tried

            • RUN . setting.env & . setting but didn't work
            • change the file name into setting.env and then RUN . ./setting.env & . ./setting & ["/bin/bash", "-c", "source ~/.setting.env"] also didn't work...

            I really appreciate your help!

            It seems like .env file is not contained in your image.

            Try to execute source .env after copying .env file into the image.

            Does gorm interpret the content of a struct with a logical OR?
            Asked 2022-Feb-18 at 13:27

            New to SQL, I am writing as an exercise an API middleware that checks if the information contained in some headers match a database entry ("token-based authentication"). Database access is based on GORM.

            To this, I have defined my ORM as follows:



            Answered 2022-Feb-18 at 13:27

            The gorm.io documentation says the following on the use of structs in Where conditionals:

            When querying with struct, GORM will only query with non-zero fields, that means if your field’s value is 0, '', false or other zero values, it won’t be used to build query conditions ...

            The suggested solution to this is:

            To include zero values in the query conditions, you can use a map, which will include all key-values as query conditions ...

            So, when the token header or both headers are empty, but you still want to include them in the WHERE clause of the generated query, you need to use a map instead of the struct as the argument to the Where method.

            When connecting to the MySQL database, ensure you leverage the parseTime and loc parameters as per the docs:

            to scan MySQL DATE and DATETIME values into time.Time variables, which is the logical equivalent in Go to DATE and DATETIME in MySQL. You can do that by changing the internal output type from []byte to time.Time with the DSN parameter parseTime=true. You can set the default time.Time location with the loc DSN parameter.

            to generate a DSN connection strings to set parseTime & loc see i.e.
