kandi X-RAY | gorp Summary

gorp is a Go library typically used in Database applications. gorp has no bugs, it has no vulnerabilities, it has a Permissive License and it has medium support. You can download it from GitHub.

I hesitate to call gorp an ORM. Go doesn't really have objects, at least not in the classic Smalltalk/Java sense. There goes the "O". gorp doesn't know anything about the relationships between your structs (at least not yet). So the "R" is questionable too (but I use it in the name because, well, it seemed more clever). The "M" is alive and well. Given some Go structs and a database, gorp should remove a fair amount of boilerplate busy-work from your code. I hope that gorp saves you time, minimizes the drudgery of getting data in and out of your database, and helps your code focus on algorithms, not infrastructure.

Build dynamic (conditional) WHERE SQL query in Golang

Asked 2020-Apr-08 at 19:35

I'm using golang, go_reform, PostgreSQL. What i want to do is a REST search utility, and all went fine until I faced with conditional search query. "Conditional" here means I have 10 columns in a table to search in, and there may be ton of combinations so I can't handle them all separately. What i need is a query builder, but I have no understanding how can I implement this in Go. For now I have an idea like this, but it seems not really efficient

From the docs for that second parameter:

The fully qualified name of the preferred type.

(emphasis mine).

You need to pass the fully-qualified name of the type, including the namespace. So "foopy.Gorp".

How to serve static files for all pages, not just a few

Asked 2019-May-11 at 13:47

I'm having a problem with my Go project where one route handles CSS fine and another route's CSS is broken. The CSS used to work on both pages, but now it isn't loading for /login.html.

I know that I'm properly stripping the prefix for the /static/ folder because it's working in once place and not another. I also directly copied and pasted the header code from the working page to the not-working page (being careful to use the correct css file).

Negroni is showing that the application is making the call to the correct location:

How can I call dbmap.Insert(interface{}) from another function?

Asked 2019-Apr-04 at 12:30

I have a bunch of very similar structs (A and B in the example) whose instances I want to handle in some function ( f() in the example) and then insert them into my database. I figured I could handle that with the empty interface somehow, but it seems this is not the solution as I get the error:

If you are calling you func like f(&a). You should call inside func f just dbmap.Insert(i), because your value is already a pointer. So your func will look like

ANSWER

Answered 2018-Apr-13 at 23:53

The answer came down to case sensitivity interaction between Go and postgres. Peter's comment essentially answers the question, but anyone reading this might want more explanation. Go only exports objects that are capitalized, while postgres defaults to interpreting column names as lower case. So I needed structs that were uppercase mapped to lowercase columns (unless I wanted to go through quoting every single uppercase column name). To do this, use tags in your struct, essentially telling Go to call it one thing, while postgres calls it another. Your new structs should looks like this:

ANSWER

Answered 2018-Feb-19 at 21:04

you want to end transaction, not close a declared cursor. commit does it. you can run multiple queries in one transaction - this is why you see the result without committing.

the pg_stat_activity.state values are: active when you run the statement (eg, begin transaction; or fetch cursos), idle in transaction when you don't currently run statements, but the transaction remains begun and lastly idle, after you run end or commit, so the transaction is over. After you disconnect the session ends and there's no row in pg_stat_activity at all...
