如何使用 python-arango 在 arangodb 中插入带有变量的数据

Question

I try to insert data from a variable and can't find a way to do this, can someone help me? something like this:

name = "mark"
surname = "clark"

db.collection('user').insert([{'username': @name, 'usersurname': @surname}])

thanks!

The "db.collection.insert" function is intended to work with objects/arrays, and does not support "variables" as such. In this case, you would use some sort of loop:

list_of_persons = [ {name: 'mark', surname: 'clark'} ]
for p in list_of_persons:
    db.collection('user').insert({'username': p.name, 'usersurname': p.surname})

Since variables are an AQL construct, they only supported in the query / cursor interface. Here you can specify the variable in the AQL (like @myVar ) and specify a " bind variable " in the body of the call. You will have to read the docs for specific implementation, as they all differ slightly.
