    1. COStack Level too deep means that you have an infinite loop somewhere. You don't have a method that calls itself somewhere in the update action do you?

    2. COnope, that was the first thing i checked. the model/controller is pretty basic. i realised that the update action with an file upload does not work in the other models too. so i'm pretty sure it's a carrierwave "bug".

    3. COI'm guessing an ActiveRecord callback may be responsible. Can you post your Account model?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
