Update multiple columns at the same time

Hello,

Thanks for this very useful tool. I wanted to dynamically update multiple columns at the same time through a loop but I didn’t figure how to do it. Here is an simple example that I tried

columns = {"key1" : "value1", "key2 : "value2"}
update_query = Query.update(table_to_update).where(table_to_update.id == 1)
for key in columns:
    update_query.set(key, columns[key])

A str(update_query) returns an empty string when I was expecting an UPDATE query with key1 and key2 and I saw that the __updates has been reinitialized to []

Is there a solution for this issue?

Thanks

Is this the best way to create an update statement with multiple sets?

@alamart you are missing the extra assignment @inkmix suggested.

The code you pasted above needs test_update_query = test_update_query.set(key, columns_test[key]) instead of test_update_query.set(key, columns_test[key])
