(31 answers)
Closed 5 years ago.
I am storing some query in json file. the query is little bit lengthy. I want to store these query in multiple lines to show query clearly. In C# when we have like this query we put in the front of query # .. Is there any special key to put in the front of json string?
below is image what I mean by this.
No, there is no way to do this; newlines are not allowed in JSON strings [1].

How to "pretty" format JSON output in Ruby on Rails
(20 answers)
Closed 3 years ago.
I've run into a situation where I'm retrieving a json string in ruby, but I'm attempting to write it to a file structured like your usual json file (for example:
{
"top":{
"mid1":"bot1",
"mid2":"bot2"
}
}
However, the way the json string is structured is like so:
{"top":{"mid1":"bot1","mid2":"bot2"}}
I've seen other posts mention doing JSON.parse in order to get what I want, however that just causes it to look like this:
{"top"=>{"mid1"=>"bot1", "mid2"=>"bot2"}}
Is there a way that I can just convert the json string into what it looks like in the first code block above?
The first representation is JSON. The decoded version is Ruby's internal representation. If you want to go back to JSON, JSON.dump(...) will reconvert it.
Keep in mind this is just presentation. The data is the same.
You may be interested in the pp method as that produces nice, structured debugging output.

MongoDB: How to query over a json string?

In the context of metabase:
I am applying the following one-liner query to extract a particular field from a collection of mongodb documents:
[{"$project":{"myName":"$field1.field2" }},
{"$match":{"_id":{"$eq":"blah"}}} ]
myName is a string field that is in fact a serialized JSON object.
How can I adapt the pipeline above, perhaps using JSON.parse(), to pull out fields nested further down the JSON hierarchy?
Part II: How would I add a final step to extract some of those deeply nested fields? The situation is further complicated because the document structure is not consistent between documents...
Thanks!

How to document dynamic query parameter names in OpenAPI (Swagger)?
(2 answers)
Closed 3 years ago.
I have the scenario where an endpoint can accept 'N' number of query parameters with a non-predetermined name and value i.e. I have no idea what query parameters someone might pass in e.g.
?i=can&pass=anything&in=here
How would I describe the above using the Swagger specification?
Looks like it's not supported in the version 2.0 of the OpenAPI specification, but it may be addressed in future versions.
This issue and this pull request can give you more details.

I have the JSON like this:
{"message":"[{\"file_name\":\"1464312906_84174_upload.jpg\",\"file_url\":\"uploads\\/tmp\\/1464312906_84174_upload.jpg\"}]","code":200}
How to get the string "1464312906_84174_upload.jpg" by JSON Expression?
message appears to be a JSON-encoded array. So parse it and then access the property you want.
JSON.parse(data.message)[0].file_name
Replace data with the variable containing the object you showed in the question.

What's the difference between parse tree and AST?
I need to know what is the difference between abstract parse trees and parse trees.
From wikipedia:
Parse trees are distinct from abstract syntax trees (also known simply as syntax trees), in that their structure and elements more concretely reflect the syntax of the input language.
