newb question, apologies if this is covered elsewhere
my sql query returns a table with categories from 1 to 8 in the category field and a second corresponding row with expenses. (in the screenshot there is just one row but there could be up to 8)
I would like to (in another script) be able to utilize something like table_output[1]['expense'] and get 225. however I can only manage json format
things tried:
Suggestions?
Hey @lee_walter!
Maybe something like this could work as a transformer on that query?
const categorizedData = {};
data.forEach(row => {
categorizedData[row.category] = {expense: row.expense};
});
return categorizedData;Hi Kabirdas,
I like where you are going . And your answer connected some dots for me about the power of transformers.
However, I am getting an error
"Could not evaluate transformer in Error: data.forEach is not a function"
I tried as per javascript - TypeError: data.forEach is not a function - Stack Overflow to first do JSON.parse(data). This lead me to a new error "Unexpected token o in JSON at position 1
if it helps here is a screenshot of what the untransformed data looks like
Thanks for your help!
Ah! You'll want to first do formatDataAsArray then, try this?
const categorizedData = {};
formatDataAsArray(data).forEach(row => {
categorizedData[row.category] = {expense: row.expense};
});
return categorizedData;Thanks, that worked
