kandi X-RAY | gabs Summary
Gabs is a small utility for dealing with dynamic or unknown JSON structures in Go. It's pretty much just a helpful wrapper for navigating hierarchies of map[string]interface{} objects provided by the encoding/json package. It does nothing spectacular apart from being fabulous. If you're migrating from version 1 check out migration.md for guidance.

QUESTION
I am struggling to use Live data on an MVVM pattern. The app is supposed to:
- Fetch data from an API (which it does correctly)
- Store that data in the Live data object from the ViewModel
- Then the fragment calls the Observer method to fill the recyclerView.
The problem comes in point 3, it does nothing, and I cannot find the solution.
Here is the relevant code. (If I'm missing something, I will try to answer as quickly as possible)

Answered 2022-Jan-11 at 14:06I think you don't need to switch Coroutine contexts. A few changes I'd expect if I were reviewing this code:
This should all be in the same IO
context. You then postValue
to your liveData.
QUESTION
Suppose we want to unmarshal the JSON string {"e": "foo", "E": 1}
.
Unmarshalling using the type messageUppercaseE
works like expected. When using the type message
though, the error json: cannot unmarshal number into Go struct field message.e of type string
is returned.
- Why are we not able to unmarshal the JSON, if only the
"e"
struct tag is present? - How would I be able to unmarshal the JSON? (I know that I am able to do this via Jeffail/gabs, but would like to stick to the type based approach.)
ANSWER
Answered 2021-Sep-10 at 16:05Quoting the docs for unmarshal:
To unmarshal JSON into a struct, Unmarshal matches incoming object keys to the keys used by Marshal (either the struct field name or its tag), preferring an exact match but also accepting a case-insensitive match.
In this case, it is the case-insensitive match that causes the trouble.

ANSWER
Answered 2020-Oct-22 at 06:24As @AkhileshMishra mentioned, the single "
is causing the problem, replacing it with '
will solve your problem.
Regarding the "moving to next command line", psql keeps on adding on a SQL query before execution, until it finds a logical endpoint. In your case, you used single "
for which it kept on trying to find a closing "
. That's why you are not able to run clear command or any other command for that matter.
You can try putting a "
and ;
to show that you are done writing your query, then psql will identify the syntax error in your query and simply shows that. After which you will be able to run a new command.
Hope it make sense for you, let me know if you still have any doubt.
