Re: Need to Replace django default I'd with UUID field

[Jason Turner]

I would just add another column that holds the UUID value instead of
changing the default ID.

 Hi guys!

 I have something that appears to be a simple problem but I didn’t find
 anything useful anywhere. My problem is that my text in a template next to
 a Django tag keeps auto capitalizing but I don’t want this to happen.



 In the image above you can see that m³/ano and m² is not capitalized at
 all. But bellow my text keeps capitalizing.





 How can I prevent that to happen?

Re: EmptyDataError at /upload_reading while reading csv file using pandas

[Jason Turner]

Is the csv something you created? Or was it given to you?

I use pandas extensively & the times I've received that error, the issue
has been with the file itself.

Ard there blank line(s) at the top of the file?

Re: EmptyDataError at /upload_reading while reading csv file using pandas

Are you sure the file is coma delimited? This error is usually because the
file is not coma separated.
