Where in the world are you getting this id of 0 ? What database
are you using? Every DB I've worked with starts an auto-increment
sequence with a positive (e.g. 1 or higher) number...
Thanks, well spotted, that was my mistake / the bug in my program.
The id of the object was 1. But I was going to /bottles/0/edit Then in the edit action I was using that number (0), to identify the object, because I was using that number as an index to the array. Bottles.all[0] So the data from the first bottle was going into the form.
Then, when I click the button to submit the form, it posts to /bottles/1 because it was using the id of @bottle
So I need my edit action to treat the number in the url (the id), as an id and not as an index to an array.
So , in the edit action, I could use @bottle=Bottle.find(...), and then pass in the id to the find method.
So the id in the edit url will then match the id of the object, and then there's no change in id when the form is submitted.
Thanks
