Hi all,

sorry for my english, im italian.

Here is my question.

 

I have a dropdown with a simple relation. Everything works jus great.

I have this option:

 

select color:

 

                  - blue

                  - red

 

that are the right values in my db

 

i also can dont make a choice in my dropdown color ( its not a strict relation ).

 

 

 

Now i would like to have

 

select color:

                  - none ( that must be equivalent to select nothing in the case before )

                  - blue

                  - red

 

( none is NOT in my db, so it must have a null value when the form wil be submitted)

In this way user will be constricted to make a choice in the dropdown.

 

is that possible?

 

Thank a lor, GC is so beautifull!

Sorry I mean nothing not anything!

Hello and welcome to the forums [member=superdan].

What if you put a new record on this relation table with nothing (or none) on the description of the color?

hi davidoster,

thank you 4 your welcome, i read lot of your posts, you are really great!

What you say its certainly a solution, but a solution that i dont like very much cause i want to mantain tha value blank in my db instead the value null.

Really i cant override keys and values in a dropdown (or add a value in list)?
It should be very nice to do that.

Of course you can override! If the set_relation isn't doing the work you want use your own model!

P.S. Thank you for your kind words! I am just enhtusiastic about Grocery CRUD cause I really believe that it is brilliant!

[superdan]

so you think i can add a fake none value ( null ) creating a new model?
Thanks again
