Upserting a Custom object with child object that has Master-Detail Relationship

I have a custom object called "Log_Entry__c" and a child object that has a Master-Detail Relationship called "Details__c". I've tried a handful of different ways, but I haven't been successfully create this child object on "Log_Entry__c". I've tried assigning the child object to the "Details", "DetailsId", "Details__r", and "Details__c" keys in the "Log_Entry__c" object. It has never worked, and the error I keep getting is this:

"No such column 'Details__c' on sobject of type Log_Entry__c"

Does anyone have any guidance for how to accomplish this? I'v also tried creating a "Details__c" object where the Master-Detail field on it (called "Log") is set to the "Log_Entry__c" id that I'm trying to link it with - but this was not successful either.

I'm writing this in Python using the simple-salesforce library (https://github.com/simple-salesforce/simple-salesforce) 

Thank you in advance, any advice will help! :)

Hi,

Usually when you refer child object from parent you have to call in this way 

Log_Entry__c.Details__r

Please refer below link.

If this helps you mark it as solved.

Thanks and Regards
